Presentation of Financial Information

As used in this Annual Report on Form 20-F, or “Annual Report,” unless the context otherwise requires, references to “we,” “us,” “our,” “Company,” “BVN” and “Buenaventura” mean Compañía de Minas Buenaventura S.A.A. and its consolidated subsidiaries. Unless otherwise specified or the context otherwise requires, references to “$,” “US$,” “Dollars” and “U.S. Dollars” are to United States Dollars, and references to “S/.,” “Sol” or “Soles” are to Peruvian Soles, the legal currency of the Republic of Peru, or “Peru.”

Unless otherwise specified, references to a value denominated in “t” or “tons” refers to tons; references to a value denominated “DST” refers to dry short tons; the terms “g” or “gr” refer to metric grams; the terms “oz.” or “ounces” refer to troy ounces of a fineness of 999.9 parts per 1,000, equal to 31.1035 grams.

Until December 31, 2010, we presented our consolidated financial statements, which we refer to as our Financial Statements, in conformity with accounting principles generally accepted in Peru, or “Peruvian GAAP.” Effective January 1, 2011, we began presenting our consolidated financial statements in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (the “IASB”).

Pursuant to the rules of the United States Securities and Exchange Commission, or the SEC, this Annual Report includes certain separate financial statements and other financial information of Minera Yanacocha S.R.L., or “Yanacocha,” and Sociedad Minera Cerro Verde S.A.A., or “Cerro Verde.” Yanacocha and Cerro Verde maintain their financial books and records in U.S. Dollars and present their financial statements in accordance with IFRS as issued by the IASB.

We record our investments in Yanacocha and Cerro Verde in accordance with the equity method as described in “Item 5. Operating and Financial Review and Prospects—Buenaventura—General” and Note 2.4(f) to the Financial Statements. Our partnership interest in Yanacocha was calculated at 43.65% for the years ended December 31, 2013, 2014 and 2015. As of December 31, 2013, 2014 and 2015, our equity interest in Cerro Verde was 19.58%.

Forward-Looking Statements

This Annual Report contains “forward-looking statements” as defined in the U.S. Private Securities Litigation Reform Act of 1995 and are intended to be covered by the safe harbor provided for under these sections. Our forward-looking statements are based on management’s assumptions and beliefs in light of the information currently available to it and may include, without limitation:

| · | our, Yanacocha’s and Cerro Verde’s costs and expenses;

| · | estimates of future costs applicable to sales;

| · | estimates of future exploration and production results;

| · | plans for capital expenditures;

| · | expected commencement dates of mining or metal production operations; and

| · | estimates regarding potential cost savings and operating performance.

The words “anticipate,” “may,” “can,” “plan,” “believe,” “estimate,” “expect,” “project,” “intend,” “likely,” “will,” “should,” “to be” and any similar expressions are intended to identify those assertions as forward-looking statements. In making any forward-looking statements, we believe that the expectations are based on reasonable assumptions. We caution readers that those statements are not guarantees of future performance and our actual results may differ materially from those anticipated, projected or assumed in the forward-looking statements. Important factors that can cause our actual results to differ materially from those anticipated in the forward-looking statements include:

| 1 |

| · | our, Yanacocha’s and Cerro Verde’s results of exploration;

| · | the results of our joint ventures and our share of the production of, and the income received from, such joint ventures;

| · | commodity prices;

| · | production rates;

| · | geological and metallurgical assumptions;

| · | industry risks;

| · | timing of receipt of necessary governmental permits or approvals;

| · | regulatory changes;

| · | political risks;

| · | inaccurate estimates of reserves or Mineralized Material Not in Reserve;

| · | anti-mining protests or other potential issues with local community relationships;

| · | labor relations;

| · | environmental risks; and

| · | other factors described in more detail under “Item 3. Key Information — D. Risk Factors.”

Many of the assumptions on which our forward-looking statements are based are likely to change after our forward-looking statements are made, including, for example, commodity prices, which we cannot control, and our, Yanacocha’s and Cerro Verde’s production volumes and costs, some aspects of which we may or may not be able to control. Further, we may make changes to our business plans that could or will affect our results. We do not intend to update our forward-looking statements, notwithstanding any changes in our assumptions, changes in our business plans, our actual experience or other changes, and we undertake no obligation to update any forward-looking statements more frequently than required by applicable securities laws.

Factors Relating to the Company

Our financial performance is highly dependent on the performance of our partners under our mining exploration and operating agreements.

Our participation in joint venture mining exploration projects and mining operations with other experienced mining companies is an integral part of our business strategy. Our partners, co-venturers and other shareholders in these projects generally contribute capital to cover the expenses of the joint venture or provide critical technological, management and organizational expertise. The results of these projects can be highly dependent upon the efforts of our joint venture partners and we rely on them to fulfill their obligations under our agreements. For example, our Yanacocha joint venture with Newmont Mining Corporation, a Delaware corporation, or Newmont Mining, depends on Newmont Peru Limited, Peruvian Branch, or “Newmont Peru,” to provide management and other expertise to the Yanacocha project. If our counterparts do not carry out their obligations to us or to third parties, or any disputes arise with respect to the parties’ respective rights and obligations, the value of our investment in the applicable project could be adversely affected and we could incur significant expense in enforcing our rights or pursuing remedies. We cannot assure you that our current or future partners will fulfill their obligations under our agreements. In addition, we may be unable to exert control over strategic decisions made in respect of such properties. For example, we currently depend on Newmont Peru to conduct operations at Yanacocha and the Conga project, and should Yanacocha be unable to continue with the current development plan at the Conga project, our mining partners in this project may reprioritize and reallocate capital to development alternatives. See “Item 4. Information on the Company – Yanacocha” and “Item 4. Information on the Company – Buenaventura – B. Business Overview – Exploration.”

Our financial performance is highly dependent on the prices of gold, silver, copper and other metals.

The results of our operations are significantly affected by the market price of specific metals, which are cyclical and subject to substantial price fluctuations. Our revenues and the revenues of Yanacocha, in which we have a material equity investment, are derived primarily from the sale of gold and silver, and the revenues of Cerro Verde, in which we have a material equity investment, are derived primarily from copper sales. The prices that we, Yanacocha and Cerro Verde obtain for gold, silver, copper and ore concentrates containing such metals, as applicable, are directly related to world market prices for such metals. Such prices have historically fluctuated widely and are affected by numerous factors beyond our control, including (i) the overall demand for and worldwide supply of gold, silver, copper and other metals; (ii) levels of supply and demand for a broad range of industrial products; (iii) the availability and price of competing commodities; (iv) international economic and political trends; (v) currency exchange fluctuations (specifically, the U.S. Dollar relative to other currencies); (vi) expectations with respect to the rate of inflation; (vii) interest rates; (viii) actions of commodity markets participants; and (ix) global or regional political or economic crises.

We have in the past engaged in hedging activities, such as forward sales and option contracts, to minimize our exposure to fluctuations in the prices of gold, silver and other metals; however, we and our wholly-owned subsidiaries no longer hedge the price at which our gold and silver will be sold. In addition, neither Yanacocha nor Cerro Verde engages in hedging activities. As a result, the prices at which we, Yanacocha and Cerro Verde sell gold, silver, copper and ore concentrates, as applicable, are fully exposed to the effects of changes in prevailing market prices. See “Item 11. Quantitative and Qualitative Disclosures About Market Risk” and Note 33 to the Financial Statements. For information on gold and silver prices for each of the years in the five-year period ended December 31, 2015, see “Item 4. Information on the Company – Buenaventura – B. Business Overview –Sales of Metal Concentrates.”

On December 31, 2015 and March 31, 2016, the morning fixing price for gold on the London Bullion Market was US$1,060.25 per ounce and US$1,233.6 per ounce, respectively. On December 31, 2015 and March 31, 2016, the afternoon fixing spot price of silver on the London market, or “London Spot,” was US$13.82 per ounce and US$15.38 per ounce, respectively. On December 31, 2015 and March 31, 2016, the London Metal Exchange Settlement price for copper was US$4,702 per ton and US$4,855.5, per ton, respectively.

The world market prices of gold, silver and copper have historically fluctuated widely. We cannot predict whether metal prices will rise or fall in the future. A continued decline in the market price of one or more of these metals could adversely impact our revenues, net income and cash flows and adversely affect our ability to meet our financial obligations. If prices of gold, silver and/or copper should decline below our cash costs of production and remain at such levels for any sustained period, we could determine that it is not economically feasible to continue production at any or all of our mines. We may also curtail or suspend some or all of our exploration activities, with the result that our depleted reserves are not replaced. This could further reduce revenues by reducing or eliminating the profit that we currently expect from reserves. Such declines in price and/or reductions in operations could cause significant volatility in our financial performance and adversely affect the trading prices of our Common Shares and ADSs.

Economic, mining and other regulatory policies of the Peruvian government, as well as political, regulatory and economic developments in Peru, may have an adverse impact on our, Yanacocha’s and Cerro Verde’s businesses.

Our, Yanacocha’s and Cerro Verde’s activities in Peru require us to obtain mining concessions or provisional permits for exploration and processing concessions for the treatment of mining ores from the Peruvian Ministry of Energy and Mines (the “MEM”). Under Peru’s current legal and regulatory regime, these mining and processing rights are maintained by meeting a minimum annual level of production or investment and by the annual payment of a concession fee. A fine is payable for the years in which minimum production or investment requirements are not met. Although we are, and Yanacocha and Cerro Verde have informed us that they are, current in the payment of all amounts due in respect of mining and processing concessions, failure to pay such concession fees, processing fees or related fines for two consecutive years could result in the loss of one or more mining rights and processing concessions, as the case may be.

Mining companies are also required to pay the Peruvian government mining royalties and/or mining taxes. See “Item 4. Information on the Company – Buenaventura – B. Business Overview – Regulatory Framework – Mining Royalties and Taxes.” We cannot assure you that the Peruvian government will not impose additional mining royalties or taxes in the future or that such mining royalties or taxes will not have an adverse effect on our, Yanacocha’s or Cerro Verde’s results of operations or financial condition. Future regulatory changes, changes in the interpretation of existing regulations or stricter enforcement of such regulations, including changes to our concession agreements, may increase our compliance costs and could potentially require us to alter our operations. We cannot assure you that future regulatory changes will not adversely affect our business, financial condition or results of operations.

Environmental and other laws and regulations may increase our costs of doing business, restrict our operations or result in operational delays.

Our, Yanacocha’s and Cerro Verde’s exploration, mining and milling activities, as well our and Yanacocha’s smelting and refining activities, are subject to a number of Peruvian laws and regulations, including environmental laws and regulations.

Additional matters subject to regulation include, but are not limited to, concession fees, transportation, production, water use and discharges, power use and generation, use and storage of explosives, surface rights, housing and other facilities for workers, reclamation, taxation, labor standards, mine safety and occupational health.

We anticipate additional laws and regulations will be enacted over time with respect to environmental matters. The development of more stringent environmental protection programs in Peru could impose constraints and additional costs on our, Yanacocha’s and Cerro Verde’s operations and require us, Yanacocha and Cerro Verde to make significant capital expenditures in the future. Although we believe that we are substantially in compliance, and Yanacocha and Cerro Verde have advised us that they are substantially in compliance, with all applicable environmental regulations, we cannot assure you that future legislative or regulatory developments will not have an adverse effect on our, Yanacocha’s or Cerro Verde’s business or results of operations. See “Item 4. Information on the Company – Buenaventura – B. Business Overview – Regulatory Framework – Environmental Matters” and “—Permits” and “Item 4. Information on the Company – Yanacocha – B. Business Overview – Regulation, Permit and Environmental Matters.”

Our and Yanacocha’s ability to successfully obtain key permits and approvals to explore for, develop and successfully operate mines will likely depend on our and Yanacocha’s ability to do so in a manner that is consistent with the creation of social and economic benefits in the surrounding communities. Our and Yanacocha’s ability to obtain permits and approvals and to successfully operate in particular communities or to obtain financing may be adversely impacted by real or perceived detrimental events associated with our and Yanacocha’s activities or those of other mining companies affecting the environment, human health and safety or the surrounding communities. Delays in obtaining or failure to obtain government permits and approvals may adversely affect our and Yanacocha’s operations, including our and Yanacocha’s ability to explore or develop properties, commence production or continue operations.

Our metals exploration efforts are highly speculative in nature and may not be successful.

Precious metals exploration, particularly gold exploration, is highly speculative in nature, involves many risks and frequently is unsuccessful. We cannot assure you that our, Yanacocha’s or Cerro Verde’s metals exploration efforts will be successful. Once mineralization is discovered, it may take a number of years from the initial phases of drilling before production is possible, during which time the economic feasibility of production may change. Substantial expenditures are required to establish proven and probable ore reserves through drilling, to determine metallurgical processes to extract the metals from the ore and, in the case of new properties, to construct mining and processing facilities. As a result of these uncertainties, we cannot assure you that our or Yanacocha’s exploration programs will result in the expansion or replacement of current production with new proven and probable ore reserves.

| 10 |

We base our estimates of proven and probable ore reserves and estimates of future cash operating costs largely on the interpretation of geologic data obtained from drill holes and other sampling techniques, and feasibility studies. Advanced exploration projects have no operating history upon which to base estimates of proven and probable ore reserves and estimates of future cash operating costs. Such estimates are, to a large extent, based upon the interpretation of geologic data obtained from drill holes and other sampling techniques, and feasibility studies which derive estimates of cash operating costs based upon anticipated tonnage and grades of ore to be mined and processed, the configuration of the ore body, expected recovery rates of the mineral from the ore, comparable facility and equipment operating costs, anticipated climatic conditions and other factors. As a result, it is possible that actual cash operating costs and economic returns based upon proven and probable ore reserves may differ significantly from those originally estimated. Moreover, significant decreases in actual over expected prices may mean reserves, once found, will be uneconomical to produce. It is not unusual in new mining operations to experience unexpected problems during the start-up phase. See “Item 4. Information on the Company – Buenaventura – D. Property, Plants and Equipment – Our Properties – Reserves,” “– Yanacocha – D. Property, Plants and Equipment – Yanacocha’s Properties – Reserves” and “Item 5. Operating and Financial Review and Prospects – Cerro Verde – A. Operating Results” for the price per ounce used by us, Yanacocha and Cerro Verde, respectively, to calculate our respective proven and probable reserves.

Increased operating costs could affect our profitability.

Costs at any particular mining location frequently are subject to variation due to a number of factors, such as changing ore grade, changing metallurgy and revisions to mine plans in response to the physical shape and location of the ore body. In addition, costs are affected by the price of commodities, such as fuel and electricity, as well as by the price of labor. Commodity costs are at times subject to volatile price movements, including increases that could make production at certain operations less profitable. Reported costs may be affected by changes in accounting standards. A material increase in costs at any significant location could have a significant effect on our profitability.

Our business is capital-intensive and we may not be able to finance necessary capital expenditures required to execute our business plans.

Precious metals exploration requires substantial capital expenditures for the exploration, extraction, production and processing stages and for machinery, equipment and experienced personnel. Our estimates of the capital required for our projects may be preliminary or based on assumptions we have made about the mineral deposits, equipment, labor, permits and other factors required to complete our projects. If any of these estimates or assumptions change, the actual timing and amount of capital required may vary significantly from our current anticipated costs. In addition, we may require additional funds in the event of unforeseen delays, cost overruns, design changes or other unanticipated expenses. We may also incur debt in future periods or reduce our holdings of cash and cash equivalents in connection with funding future acquisitions, existing operations, capital expenditures or in pursuing other business opportunities. Our ability to meet our payment obligations will depend on our future financial performance, which will be affected by financial, business, economic and other factors, many of which we are unable to control. There can be no assurance that we or Yanacocha will generate sufficient cash flow and/or that we will have access to sufficient external sources of funds in the form of outside investment or loans to continue exploration activities at the same or higher levels than in the past or that we will be able to obtain additional financing, if necessary, on a timely basis and on commercially acceptable terms.

Estimates of proven and probable reserves are subject to uncertainties and the volume and grade of ore actually recovered may vary from our estimates.

The proven and probable ore reserve figures presented in this Annual Report are our, Yanacocha’s and Cerro Verde’s estimates, and there can be no assurance that the estimated levels of recovery of gold, silver, copper and certain other metals will be realized. Such estimates depend on geological interpretation and statistical inferences or assumptions drawn from drilling and sampling analysis, which may prove to be materially inaccurate. Actual mineralization or formations may be different from those predicted. As a result, reserve estimates may require revision based on further exploration, development activity or actual production experience, which could materially and adversely affect such estimates. No assurance can be given that our, Yanacocha’s or Cerro Verde’s mineral resources constitute or will be converted into reserves. Market price fluctuations of gold, silver and other metals, as well as increased production costs or reduced recovery rates, may render proven and probable ore reserves containing relatively lower grades of mineralization uneconomic to exploit and may ultimately result in a restatement of proven and probable ore reserves. Moreover, short-term operating factors relating to the reserves, such as the processing of different types of ore or ore grades, could adversely affect our or Yanacocha’s profitability in any particular accounting period. See “Item 4. Information on the Company – Buenaventura – D. Property, Plants and Equipment – Our Properties—Reserves” and “Item 4. Information on the Company – D. Property, Plants and Equipment – Yanacocha – Yanacocha’s Properties – Reserves.”

| 11 |

We and Yanacocha may be unable to replace reserves as they become depleted by production.

As we and Yanacocha produce gold, silver, zinc and other metals, we and Yanacocha deplete our respective ore reserves for such metals. To maintain production levels, we and Yanacocha must replace depleted reserves by exploiting known ore bodies and locating new deposits. Exploration for gold, silver and the other metals produced is highly speculative in nature. Our and Yanacocha’s exploration projects involve significant risks and are often unsuccessful. Once a site is discovered with mineralization, we and Yanacocha may require several years between initial drilling and mineral production, and the economic feasibility of production may change during such period. Substantial expenditures are required to establish proven and probable reserves and to construct mining and processing facilities. There can be no assurance that current or future exploration projects will be successful and there is a risk that our depletion of reserves will not be offset by new discoveries. See “Item 4. Information on the Company – Buenaventura – B. Business Overview—Exploration,” “– Yanacocha – B. Business Overview – Exploration,” “– D. Property, Plants and Equipment – Reserves,” “– Yanacocha’s Properties – Reserves” and “Item 5. Operating and Financial Review and Prospects – Cerro Verde – A. Operating Results” for a summary of our, Yanacocha’s and Cerro Verde’s estimated proven and probable reserves as of December 31, 2015.

Our operations are subject to risks, many of which are not insurable.

The business of mining, smelting and refining gold, silver, copper and other metals is generally subject to a number of risks and hazards, including industrial accidents, labor disputes, unavailability of materials and equipment, unusual or unexpected geological conditions, changes in the regulatory environment, environmental hazards and weather and other natural phenomena such as earthquakes, most of which are beyond our control. Such occurrences could result in damage to, or destruction of, mining properties or production facilities, personal injury or death, environmental damage, delays in mining, monetary losses and possible legal liability. We, Yanacocha, and Cerro Verde each maintain insurance against risks that are typical in the mining industry in Peru and in amounts that we, Yanacocha and Cerro Verde believe to be adequate but which may not provide adequate coverage in certain circumstances. No assurance can be given that such insurance will continue to be available at economically feasible premiums or at all. Insurance against certain risks (including certain liabilities for environmental pollution or other hazards as a result of exploration and production) is not generally available to us or to other companies within the industry.

Increases in equipment costs, energy costs and other production costs, disruptions in energy supply and shortages in equipment and skilled labor may adversely affect our results of operations.

In recent years, there has been a significant increase in mining activity worldwide in response to increased demand and significant increases in the prices of natural resources. The opening of new mines and the expansion of existing ones has led to increased demand for, and increased costs and shortages of, equipment, supplies and experienced personnel. These cost increases have significantly increased overall operating and capital budgets of companies like ours, and continuing shortages could affect the timing and feasibility of expansion projects.

Energy represents a significant portion of our production costs. Our principal energy sources are electricity, purchased petroleum products, natural gas and coal. An inability to procure sufficient energy at reasonable prices or disruptions in energy supply could adversely affect our profits, cash flow and growth opportunities. Our production costs are also affected by the prices of commodities we consume or use in our operations, such as sulfuric acid, grinding media, steel, reagents, liners, explosives and diluents. The prices of such commodities are influenced by supply and demand trends affecting the mining industry in general and other factors outside our control and such prices are at times subject to volatile movements. Increases in the cost of these commodities or disruptions in energy supply could make our operations less profitable, even in an environment of relatively high copper, gold or silver prices. Increases in the costs of commodities that we consume or use may also significantly affect the capital costs of new projects.

| 12 |

We may be adversely affected by labor disputes.

Our ability to achieve our goals and objectives is dependent, in part, on maintaining good relations with our employees. A prolonged labor disruption at any of our material properties could have a material adverse impact on our results of operations. We, Compañía Minera Coimolache S.A., or “Coimolache,” Yanacocha and Cerro Verde have all experienced strikes or other labor-related work stoppages in the past. In June 2015, El Brocal experienced a two-day work stoppage at its concentrator plant in Huaraucaca in connection with the negotiation of salary and the collective bargaining agreement. Subsequently, in May and June 2015, we experienced a strike at the Uchucchacua mine that lasted for twenty-nine days and was staged by workers’ and contractors’ unions claiming unsuitable working conditions.

As of December 31, 2015, unions represented approximately 39% of the employees of our mining companies on a consolidated basis. Although we consider our relationship with our employees to be positive, there can be no assurance that we will not experience strikes or other labor-related work stoppages that could have a material adverse effect on our operations and/or operating results in the future.

Our, Yanacocha and Cerro Verde’s operations are subject to political and social risks.

Our, Yanacocha and Cerro Verde´s exploration and production activities are potentially subject to political and social risks. Over the past several years, we and Yanacocha have been the target of local political protests. In recent years, certain areas in the south and northern highlands of Peru with significant mining developments have experienced strikes and protests related to the environmental impact of mining activities. Such strikes and protests have resulted in commercial disruptions and a climate of uncertainty with respect to future mining projects. As a result of local political and community protests, construction and development activities at the Conga project were largely suspended in November 2011. The results of the Peruvian Central Government’s Environmental Impact Assessment (“EIA”) independent review were reported on April 20, 2012. The review indicated the project’s EIA met Peruvian and international standards. The review made recommendations to provide additional water capacity and social funds, which Yanacocha has largely accepted. Yanacocha announced the decision to advance the project on a “water-first” basis on June 22, 2012. In the first half of 2014, a Conga Restart Study was completed to identify and test alternatives to advancing development of the project. Following this assessment, a new plan was developed to reduce spending to focus only on the most critical work (protecting people and assets, engaging with communities, and maintaining existing project infrastructure), while maintaining optionality. Newmont will not proceed with the full development of the Conga project without social acceptance, solid project economics and, potentially, another partner to help defray costs and risk. It is difficult to predict when or whether such events may occur. Under the current social and political environment, we do not anticipate being able to develop the Conga project in the foreseeable future. The continued delay and evaluation of other alternatives may result in a potential accounting impairment or further reclassification of mineralized material.

There can be no assurance that these types incidents will not continue or that similar incidents will not occur in areas in which we and Yanacocha operate, or that the continuation or intensification of community protests will not adversely affect our or Yanacocha’s exploration and production activities or our or Yanacocha’s results of operations or financial condition.

In addition, during 2011, Peru enacted Law No. 29785, the Law of Prior Consultation for Indigenous and Native Communities (Ley del Derecho a la Consulta Previa a los Pueblos Indígenas y Originarios, Reconocido en el Convenio 169 de la Organización Internacional del Trabajo). Implementing regulations thereunder were approved by Supreme Decree No. 001-2012-MC, which became effective on April 2, 2012. This law establishes a prior consultation procedure that the Peruvian government must undertake in concert with any local indigenous communities whose collective rights may be directly affected by new legislative or administrative measures, including the granting of new mining concessions. The implementing regulations specify the form and circumstances of the required consultation and the manner in which agreements will be formalized, and cap the consultation process at 120 calendar days. Under the law, the Peruvian governmental body responsible for issuing or approving the administrative measure or decree in question, rather than the affected local indigenous community, retains the right to approve or reject the relevant legislative or administrative matter following such consultation. However, to the extent that any future projects operated by us, Yanacocha or Cerro Verde require legislative or administrative measures that impact local indigenous communities, the required prior consultation procedure may result in delays, additional expenses or failure to obtain approval for such new project.

We could face geotechnical challenges, which could adversely impact our production and profitability.

No assurances can be given that unanticipated adverse geotechnical and hydrological conditions, such as landslides and pit wall failures, will not occur in the future or that such events will be detected in advance. Geotechnical instabilities can be difficult to predict and are often affected by risks and hazards outside of our control, such as severe weather and considerable rainfall, which may lead to periodic floods, mudslides, wall instability and seismic activity, which may result in slippage of material.

Geotechnical failures could result in limited or restricted access to mine sites, suspension of operations, government investigations, increased monitoring costs, remediation costs, loss of ore and other impacts, which could cause one or more of our projects to be less profitable than currently anticipated and could result in a material adverse effect on our results of operations and financial position.

We rely on contractors to conduct a significant portion of our operations and mine development projects.

A significant portion of our operations and mine development projects are currently conducted by contractors. As a result, our operations are subject to a number of risks, some of which are outside our control, including:

| · | failure of a contractor to perform under its agreement;

| · | interruption of operations or increased costs if a contractor ceases its business due to insolvency or other unforeseen events;

| · | failure of a contractor to comply with applicable legal and regulatory requirements, to the extent it is responsible for such compliance; and

| · | problems of a contractor with managing its workforce, labor unrest or other employment issues.

In addition, we may incur liability to third parties as a result of the actions of our contractors. The occurrence of one or more of these risks could adversely affect our results of operations and financial position.

We are not, and do not intend to become, regulated as an investment company under the U.S. Investment Company Act of 1940, as amended (the “Investment Company Act”), and if we were deemed an “investment company” under the Investment Company Act, applicable restrictions could make it impractical for us to operate as contemplated.

As of December 31, 2015, we owned a 43.65% partnership interest in Yanacocha and a 19.584% equity interest in Cerro Verde. These interests may constitute “investment securities” for purposes of the Investment Company Act.

Under the Investment Company Act, an investment company is defined in relevant part to include (i) any company that is or holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities and (ii) any company that owns or proposes to acquire investment securities having a value exceeding 40% of such company’s total assets (exclusive of certain items) on an unconsolidated basis. Issuers that are investment companies within the meaning of the Investment Company Act, and which do not qualify for an exemption from the provisions of such act, are required to register with the Securities and Exchange Commission (the “SEC”) and are subject to substantial regulations with respect to capital structure, operations, transactions with affiliates and other matters. If we were deemed to be an investment company and did not qualify for an exemption from the provisions of the Investment Company Act, we would be required to register with the SEC and would be subject to such regulations, which would be unduly burdensome and costly for us and possibly adversely impact us.

We received an order from the SEC on April 19, 1996 declaring us to be primarily engaged in a business other than that of an investment company and, therefore, not an investment company within the meaning of the Investment Company Act. We intend to conduct our operations and maintain our investments in a manner, and will take appropriate actions as necessary, to ensure we will not be deemed to be an investment company in the future. The SEC, however, upon its motion or upon application, may find that the circumstances that gave rise to the issuance of the order no longer exist, and as a result may revoke such order. There can be no assurance that such order will not be revoked.

| 14 |

Our or Yanacocha’s inability to maintain positive relationships with the communities in which we operate may affect our or Yanacocha’s reputation and financial condition.

Our and Yanacocha’s relationships with the communities in which we operate are critical to ensuring the future success of our existing operations and the construction and development of our projects. Adverse publicity generated by non-governmental organizations or local communities related to extractive industries generally, or our or Yanacocha’s operations specifically, could have an adverse effect on our reputations or financial condition and may impact our relationships with the communities in which we operate. In addition, following the enactment of Law No. 29785, the Law of Prior Consultation for Indigenous and Native Communities in 2011, the Peruvian government must undertake a prior consultation procedure in concert with local indigenous communities whose collective rights may be directly affected by new legislative or administrative measures, including the granting of new mining concessions. Implementing regulations under Law No. 29785 were approved by Supreme Decree No. 001-2012-MC, which became effective on April 2, 2012. The implementing regulations specify the form and circumstances of the required consultation and the manner in which agreements will be formalized, and cap the consultation process at 120 calendar days. Our and Yanacocha’s national reputation for maintaining positive relationships with the communities in which we operate may affect the outcome of any such prior consultation process involving approvals that we or Yanacocha seek for new projects. While we and Yanacocha are committed to operating in a socially responsible manner, there is no guarantee that our efforts in this regard will mitigate this potential risk. We and Yanacocha have implemented extensive community relations and security and safety initiatives to anticipate and manage social issues that may arise at our operations. See “Item 4. Information on the Company – Yanacocha – B. Business Overview – Social Development.”

The Conga project is located within close proximity of existing operations at Yanacocha. Due to local political and community protests, construction and development activities at the Conga project were largely suspended in November 2011. The results of the Peruvian central government-initiated Environmental Impact Study (“EIS”), independent review, announced on April 20, 2012, confirmed that Yanacocha’s initial EIS met Peruvian and international standards. The review made recommendations to provide additional water capacity and social funds, which Yanacocha has largely accepted. Yanacocha announced its decision to move the project forward on a “water first” basis on June 22, 2012, which consists of building the originally planned community water reservoirs before resuming any mine development. As a result, during 2013 the project was focused on building water reservoirs, completing the remaining engineering activities, and accepting delivery of the main equipment purchases. In 2013, the Chailhuagon reservoir was completed. There were no major improvements carried out in 2014 or 2015. There can be no assurance that Yanacocha will be able to continue to develop the Conga project. Should Yanacocha be unable to continue with the current development plan at Conga, we or our mining partners in this project may reprioritize and reallocate capital to development alternatives, which may result in a potential accounting impairment. See “Item 4. Information on the Company – Yanacocha – B. Business Overview – Exploration.”

Deterioration in our financial position or a downgrade of our ratings by a credit rating agency could increase our borrowing costs and our business relationships could be adversely affected.

Credit rating agencies could downgrade our ratings either due to factors specific to Buenaventura, a prolonged cyclical downturn in the precious metals mining industries, macroeconomic trends (such as global or regional recessions) or trends in credit and capital markets more generally. For instance, on March 22, 2016, Moody’s downgraded our unsecured corporate rating from “Ba1” to “Ba2” due to the deterioration of the commodities markets and a downturn in the precious metals mining sector, as well as concerns about our liquidity. Our unsecured rating from Fitch remains a “BBB.”

A deterioration of our financial position or a further downgrade of any of our credit ratings for any reason could increase our borrowing costs and have an adverse effect on our business relationships with customers and suppliers. A subsequent downgrade could adversely affect our existing financings, limit access to the capital or credit markets, or otherwise adversely affect the availability of other new financing on favorable terms, if at all, result in more restrictive covenants in agreements governing the terms of any future indebtedness that we incur, increase our borrowing costs, or otherwise impair our business, financial condition and operating results.

Factors Relating to Peru

Peruvian political conditions may have an adverse impact on our, Yanacocha’s and Cerro Verde’s business.

All of our, Yanacocha’s and Cerro Verde’s operations are conducted in Peru. Accordingly, our, Yanacocha’s and Cerro Verde’s business, financial condition or results of operations could be affected by changes in economic or other policies of the Peruvian government or other political, regulatory or economic developments in Peru.

During the past several decades, Peru has had a history of political instability that has included military coups and a succession of regimes with differing policies and programs. Past governments have frequently played an interventionist role in the nation’s economy and social structure. Among other things, past governments have imposed controls on prices, exchange rates and local and foreign investment as well as limitations on imports, restricted the ability of companies to dismiss employees, expropriated private sector assets (including mining companies) and prohibited the remittance of profits to foreign investors.

In the second quarter of 2011, Presidential and Congressional elections resulted in a change in government in Peru. During the third quarter of 2011, the new government enacted four new tax laws. During 2012, the new administration, under President Ollanta Humala, largely supported mining as a driver for the continued growth and future development of Peru. However, Peru will be holding its elections for President during 2016 and we cannot predict future government positions on mining concessions, land tenure, environmental regulation or taxation or assure you that future governments will maintain a generally favorable business climate and economic policies. Furthermore, the regional governor in Cajamarca, who was re-elected in October 2014, actively opposed the Conga project in 2012 and continues to reject the viability of its development. We cannot predict the future positions of either the central government or regional governments on foreign investment, mining concessions, land tenure or other regulation. Any change in government positions or laws on these issues could adversely affect the assets and operations of us, Yanacocha or Conga, which could have a material adverse effect on our business, results of operations and financial position. Regulatory changes may include increased labor regulations, environmental and other regulatory requirements, and additional taxes and royalties, and we may experience future protests, community demands and road blockages. Additionally, any inability to continue to develop the Conga project or operate at Yanacocha could have a material adverse impact on our business, results of operations and financial position if Yanacocha is not able to replace its expected production.

Inflation, reduced economic growth and fluctuations in the Sol exchange rate may adversely affect our financial condition and results of operations.

Over the past several decades, Peru has experienced periods of high inflation, slow or negative economic growth and substantial currency devaluation. The inflation rate in Peru, as measured by the Indice de Precios al Consumidor and published by Instituto Nacional de Estadística e Informática has fallen from a high of 7,649.7% in 1990 to 4.40% in 2015. The Peruvian currency has been devalued numerous times during the last 20 years. Our revenues and operating expenses are primarily denominated in U.S. Dollars. If inflation in Peru were to increase without a corresponding devaluation of the Sol relative to the U.S. Dollar, our financial position and results of operations, and the market price of our Common Shares and ADSs, could be affected. Although the Peruvian government’s stabilization plan has significantly reduced inflation, and the Peruvian economy has experienced strong growth in recent years, there can be no assurance that inflation will not increase from its current level or that such growth will continue in the future at similar rates or at all.

Among the economic circumstances that could lead to a devaluation would be the decline of Peruvian foreign reserves to inadequate levels. Peru’s foreign reserves at December 31, 2015 were US$61.54 billion as compared to US$62.35 billion at December 31, 2014. Although actual foreign reserves must be maintained at levels that will allow the succeeding government the ability to manage the Peruvian economy and to assure monetary stability in the near future, there can be no assurance that Peru will be able to maintain adequate foreign reserves to meet its foreign currency denominated obligations, or that Peru will not devalue its currency should its foreign reserves decline. See “Item 3. Key Information – A. Selected Financial Data – Exchange Rates.”

Peru’s current account deficit is being funded partially by foreign direct investment. There can be no assurance that foreign direct investment will continue at current levels, particularly if adverse political or economic developments in Peru arise, a development that may also contribute to devaluation pressure.

Deterioration in economic and market conditions in Latin America, Peru and other emerging market countries could affect the prices of our Common Shares and American Depositary Receipts (“ADRs”).

Although economic conditions are different in each country, the reaction of investors to developments in one country is likely to cause the capital markets in other countries to fluctuate. For example, political and economic events, such as the crises in Venezuela, Ecuador, Bolivia, Brazil and Argentina, have influenced investors’ perceptions of risk with regard to Peru. The negative investor reaction to developments in Latin America, particularly in our neighboring countries, may adversely affect the market for securities issued by countries in the region, cause foreign investors to decrease the flow of capital into Latin America and introduce uncertainty about plans for further integration of regional economies.

Peruvian exchange and investment control policies could affect dividends paid to holders of Common Shares and ADRs.

Peruvian law currently imposes no restrictions on the ability of companies operating in Peru to transfer foreign currency from Peru to other countries, to convert Peruvian currency into foreign currency or foreign currency into Peruvian currency or to remit dividends abroad, or on the ability of foreign investors to liquidate their investment and repatriate their capital. Before 1991, Peru had restrictive exchange controls and exchange rates. During the latter part of the 1980s, exchange restrictions prevented payment of dividends to our shareholders in the United States in U.S. Dollars. Accordingly, should such or similar controls be instituted, dividends paid to holders of Common Shares and, consequently, holders of ADRs, could be affected. There can be no assurance that the Peruvian government will continue to permit such transfers, remittances or conversion without restriction. See “Item 10. Additional Information – D. Exchange Controls.”

U.S. securities laws do not require us to disclose as much information to investors as a U.S. issuer is required to disclose, and you may receive less information about us than you might otherwise receive from a comparable U.S. company.

The corporate disclosure requirements applicable to us may not be equivalent to the requirements applicable to a U.S. company and, as a result, you may receive less information about us than you might otherwise receive in connection with a comparable U.S. company. We are subject to the periodic reporting requirements of the United States Securities Exchange Act of 1934, as amended, or the Exchange Act, that apply to “foreign private issuers.” The periodic disclosure required of foreign private issuers under the Exchange Act is more limited than the periodic disclosure required of U.S. issuers.

Holders of our securities may find it difficult to enforce judgments against us outside of Peru.

We are organized under the laws of Peru. A significant majority of our directors and officers reside outside the United States (principally in Peru). All or a substantial portion of our assets or the assets of such persons are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon us or upon such persons or to enforce against them in federal or state courts in the United States judgments predicated upon the civil liability provisions of the federal securities laws of the United States. We have been advised by our Peruvian counsel that there is uncertainty as to the enforceability, in original actions in Peruvian courts, of liabilities predicated solely under the United States federal securities laws and as to the enforceability in Peruvian courts of judgments of United States courts obtained in actions predicated upon the civil liability provisions of the United States federal securities laws.

Factors Relating to the Common Shares and ADSs

The concentration of our capital stock ownership with the Benavides Family will limit our stockholders’ ability to influence corporate matters.

As of March 31, 2016, the Benavides family, referring to certain members, and their spouses, of the immediate and extended family of Elsa Ganoza Benavides, spouse of the late Alberto Benavides de la Quintana, our founder and former Chairman (collectively, the “Benavides Family”), held 27.22% (including outstanding Common Shares and Investment Shares) of Buenaventura’s outstanding share capital. Because of the significant ownership interest the Benavides Family holds in Common Shares, the Benavides Family has the power to elect a significant number of the outstanding directors and has significant influence over the outcome of substantially all matters to be decided by a vote of shareholders.

| 17 |

In addition, under the terms of the Amended and Restated Deposit Agreement dated May 3, 2002, as further amended and restated as of November 12, 2003, among us, The Bank of New York Mellon (formerly The Bank of New York), as depositary, or the “Depositary”, and the owners and beneficial owners of ADSs, or the Amended and Restated Deposit Agreement, relating to our ADSs, if holders of ADSs do not provide the Depositary with timely instructions for the voting of Common Shares represented by such ADRs, the Depositary will be deemed to be instructed to give a person designated by us, which will likely be a member of the Benavides Family, a discretionary proxy to vote such shares, unless we inform the Depositary that we do not wish such proxy to be given.

Shareholders’ rights under Peruvian law may be fewer and less well-defined than shareholders’ rights in other countries, including the United States.

Our shareholders have fewer and less well-defined rights under applicable Peruvian law than they might have as shareholders of a corporation incorporated in a jurisdiction of the United States or certain other countries. For example, Peruvian law does not provide for proceedings by which non-controlling shareholders may file class action lawsuits or shareholder derivative actions against controlling shareholders or officers and directors, and the procedural requirements to file shareholder actions in Peru differ from those of the United States. As a result, holders of our shares may face difficulty enforcing their rights.

A sale of a substantial number of shares by the Benavides Family could have an adverse impact on the price of our Common Shares and ADSs.

The sale of a substantial number of our shares by members of the Benavides Family, or a market perception of the intention of members of the Benavides Family to sell a substantial number of shares, could materially and adversely affect prevailing market prices for the Common Shares and ADSs. There is no contractual restriction on the disposition of shares of our share capital by our shareholders, including the Benavides Family. Furthermore, under the Ley General de Sociedades Peruanas, or “Peruvian Companies Law,” any restriction on the free sale of shares in a sociedad anónima abierta (open stock company) such as we are, is null and void.

Holders of ADSs may be unable to exercise preemptive rights and accretion rights available to the Common Shares underlying the ADSs.

Holders of the ADSs are, under Peruvian law, entitled to exercise preemptive rights and accretion rights on the Common Shares underlying the ADSs in the event of any future capital increase by us unless (x) the increase is approved, expressly stating that the shareholders have no preemptive rights to subscribe and pay for the Shares to be issued in such increase, by holders of Common Shares holding at least 40% of the Common Shares at a properly called meeting with a proper quorum and (y) the increase is not designed to improve directly or indirectly the shareholding of any shareholder. However, United States holders of ADSs may not be able to exercise through the Depositary for the ADSs the preemptive rights and accretion rights for Common Shares underlying their ADSs unless a registration statement under the Securities Act of 1933, as amended, or the “Securities Act,” is effective with respect to such rights or an exemption from the registration requirement thereunder is available. Any such rights offering would have a dilutive effect upon shareholders who are unable or unwilling to exercise their rights. We intend to evaluate, at the time of any rights offering, the costs and potential liabilities associated with any registration statement as well as the associated benefits of enabling the holders of ADSs to exercise such rights and will then make a decision as to whether to file such a registration statement. Therefore, no assurance can be given that we will file any such registration statement. To the extent that holders of ADSs are unable to exercise such rights because a registration statement has not been filed and no exemption from such registration statement under the Securities Act is available, the Depositary will, to the extent practicable, sell such holders’ preemptive rights or accretion rights and distribute the net proceeds thereof, if any, to the holders of ADSs, and such holders’ equity interest in us will be diluted proportionately. The Depositary has discretion to make rights available to holders of ADSs or to dispose of such rights and to make any net proceeds available to such holders. If, by the terms of any rights offering or for any other reason, the Depositary is not able to make such rights or such net proceeds available to any holder of ADSs, the Depositary may allow the rights to lapse.

BUENAVENTURA

| A. | History and Development

Overview

We are Peru’s largest publicly traded precious metals company and are engaged in the exploration, mining and processing of gold, silver and, to a lesser extent, other metals in Peru. We currently operate the Orcopampa, Uchucchacua, Julcani, Mallay and Breapampa mines and have controlling interests in three other mining companies which operate the Colquijirca-Marcapunta, Tantahuatay and La Zanja mines. We also own an electric power transmission company, a hydroelectric plant, a processing plant and an engineering services consulting company and non-controlling interests in several other mining companies, including a significant ownership interest in Yanacocha, a Peruvian partnership that operates the largest gold mine in South America, and Cerro Verde, a Peruvian company that operates a copper mine located in the south of Peru. For the year ended December 31, 2015, our consolidated net sales were US$919.4 million and our consolidated net loss was US$375.5 million.

Discontinued operations. In 2014, the Company publicly announced its decision to sell four of its mining units: Poracota, Recuperada, Antapite and Shila-Paula. As a consequence, these mining units are presented in the Financial Statements as mining units held for sale. According to IFRS 5 “Non-current Assets Held for Sale and Discontinued Operations,” the related assets and liabilities are presented in the consolidated statement of financial position at the lower of cost and fair value less cost to sale. The disposition of these discontinued mining units is expected to be completed by December 31, 2016 through sales to third parties. See Notes 1(e) and 2.4(x) to the Financial Statements.

The table below summarizes the total production and our equity share of production for the Julcani, Orcopampa, Uchucchacua, Mallay, Breapampa, Colquijirca, La Zanja, Tantahuatay, Yanacocha and Cerro Verde mines, as well as certain small assets for divestment, for the year ended December 31, 2015:

Compañía de Minas Buenaventura S.A.A., a sociedad anónima abierta (open stock company) under the laws of Peru, was originally established in 1953 as a sociedad anónima (stock company) under the laws of Peru, and currently operates under the laws of Peru. Our registered office is located at Las Begonias 415 – Floor 19, Lima 27, Peru, telephone no. 511-419-2500. Our website may be found at http://www.buenaventura.com. The information on our website is not a part of, and is not incorporated into, this document.

History

During the first several decades of our operations, we focused on the exploration and development of silver mines in Peru, including our Julcani, Orcopampa and Uchucchacua mines. Beginning in the early 1980s, we began to explore for gold and other metals in Peru to diversify our business and reduce our dependence on silver. We expanded our mineral reserves through property acquisition and intensive exploration programs designed to increase reserves and production of gold. We also conducted exploration leading to the discovery of gold mineralization and subsequent production of gold at our Orcopampa, La Zanja, and Breapampa mines. In addition, we made significant equity investments in Yanacocha, which operates South America’s largest gold mine, Cerro Verde, which operates an open-pit copper mine in Peru, and Coimolache, which owns the Tantahuatay gold mine that we operate. As a result of these initiatives, the majority of our revenues are now derived from the production of gold.

| 19 |

In 2014, we acquired 51% of Canteras del Hallazgo S.A.C. (“CDH”), owner of the Chucapaca Project, from Minera Gold Fields Perú S.A. (“MGFPSA”). The Chucapaca Project involved a group of mining rights originally owned by MGFPSA. In 2008, Compañía de Minas Buenaventura S.A.A. entered into a contract of Mineral lease, Option of Transfer, Option to Operate a Project and Option to Acquire a Stake, with MGFPSA regarding these mineral rights.

Pursuant to this contract, Buenaventura would be the project’s operator and would retain the option to acquire 100% of the mineral rights through a payment of US$2 million. Likewise, MGFPSA would also have the option to operate a project that, during explorations conducted by Buenaventura, is identified as a project whose main mineral content is gold (a “Gold Project”), in which case a new legal entity would be created to own the mineral rights to the project. Additionally, for this new legal entity, MGFPSA is awarded the right to purchase 51% of its shares as long as it fulfills its obligation to invest in explorations a sum equivalent to three times that which Buenaventura invested during the period it was the operator.

After Buenaventura discovered the ore deposit and it was identified as a gold project, CDH was created as owner to the project’s mineral rights; at which point MGFPSA, in charge of explorations in 2009, exercised its option to purchase 51% of CDH’s shares.

In August of 2014, Buenaventura purchased the totality of MGFPSA’s shares in CDH for a sale price of US$81 million and additional payments consisting of a Net Smelter Return Royalty of 1.5% in favor of MGFPSA for mining rights constituting the Chucapaca Project. Afterwards Buenaventura merged by absorption with CDH and registered the royalties in favor of MGFPSA in the title sheet of each one of the mining rights involved. Additionally, the Chucapaca Project has been renamed the San Gabriel Project. For more information about the San Gabriel Project, see “Item 4. B. Business Overview—Exploration Projects in Non-Operating Areas.”

Business Strategy

Our strategy is to sustain our position as Peru’s largest, publicly-traded gold and silver mining company by expanding our reserves and production. We are currently engaged in an active exploration and mine development program and participate in several mining exploration projects with Newmont Mining, Southern Copper Corporation, Corporación Aceros Arequipa S.A. and Compañia de Minas Caudalosa S.A.C. In addition, we seek to increase the efficiency and capacity of our mining operations. We are aware of our social and environmental responsibilities and aim to excel in the prevention, mitigation and rehabilitation of mining-related disturbances.

Maintaining an Active Exploration Program

During 2015, we spent US$30.6 million on “exploration in non-operating areas” and US$91.5 million on “exploration in units in operations.” Our “exploration in non-operating areas” investments mainly focused on the following exploration projects: Tambomayo, Alejandra, Marcapunta and Pisacalla projects. Our “exploration in units in operations” investments were mainly focused in the Orcopampa, Uchucchacua and Julcani mining units.

In 2016, we intend to invest approximately US$70 to US$80 million in exploration in units in operations and US$10 to US$20 million mainly in the following explorations in non-operating areas: Tambomayo, Yumpag, Palla Palla and Daniela, among others.

Participation in Mining Exploration Agreements

In addition to managing and operating precious metals mines, we participate in mining exploration agreements with mining partners to reduce risks, gain exposure to new technologies and diversify revenues to include other base metals, such as copper and zinc. See “B. Business Overview – Exploration.” We believe that maintaining our focus on mining operations complements our partnership strategy because the engineering and geological expertise gained from such operations enhances our ability to participate in and contribute to those projects.

Capital Expenditures

Our capital expenditures during the past three years have related principally to the acquisition of new mining properties, construction of new facilities and renewal of plant and equipment. Capital expenditures relating to exploration are not included in the table below and are discussed separately in “B. Business Overview – Exploration.” Set forth below is information concerning capital expenditures incurred by us in respect of each of our principal operating mines (not including capital expenditures for administrative purposes or other non-mining or non-energy subsidiaries) and by category of expenditure:

We mainly financed our capital expenditures in 2014 and 2015 with internally-generated funds. We partially funded the El Brocal Expansion and the construction of the Huanza hydroelectric power plant with leasing facilities, with aggregate amounts of US$344.4 million outstanding thereunder as of December 31, 2015 (including US$156.3 and US$188.1 million, respectively). See “Item 5. Operating and Financial Review and Prospects – Buenaventura – B. Liquidity and Capital Resources – Long-Term Debt.”

We have budgeted approximately US$250 to US$300 million for capital expenditures for 2016. We continuously evaluate opportunities to expand our business within Peru, as well as in other countries as opportunities arise, and expect to continue to do so in the future. We may in the future decide to acquire part or all of the equity of, or undertake other transactions with, other companies involved in the same business as us or in other related businesses. However, there can be no assurance that we will decide to pursue any such new activity or transaction.

Exploration

We view exploration as our primary means of generating value for our shareholders maintaining a portfolio of active exploration projects at various stages of exploration for mineral resources in Peru. During 2015, we spent US$30.6 million in “exploration in non-operating areas” mainly focused in the Tambomayo, Alejandra, Marcapunta and Pisacalla projects, and US$91.5 million on “exploration in units in operations” mainly focused in the Orcopampa, Uchucchacua and Julcani mining units. During 2016, we expect to invest approximately US$80 to US$100 million in these exploration activities.

Our exploration department develops programs and budgets for individual projects each year and we allocate, subject to board approval, the proper amount to fund each particular exploration program. Because of the nature of mining exploration and to maintain flexibility to take advantage of opportunities, we allocate budgeted amounts by property or project only in the case of high probability of success. We also allocate non-budgeted amounts over the course of the year to new projects that our technical team considers highly prospective.

We have active joint venture exploration agreements with other mining companies, including Newmont Peru S.R.L., Southern Copper Corporation, Corporación Aceros Arequipa S.A. and Compañia de Minas Caudalosa S.A.C. In this way we have access to financing for exploration of our own mining properties as well as third-party properties without the costs and risks of outright acquisition, increased exposure to new exploration technologies and expansion of knowledge and sharing of experiences of management, geologists and engineers. In these mining exploration agreements, we may be the operator, an equity participant, the manager or a combination of these and other functions.

The following table lists our principal exploration projects in non-operating areas, our effective participation in each project, our partners with respect to each project, the total number of hectares in each project, observed mineralization of each project and the exploration expenditures for each project during 2014 and 2015.

The following is a brief summary of current exploration activities conducted by Buenaventura directly and through joint exploration agreements, which we believe represent the best prospects for discovering new reserves. There can be no assurance, however, that any of our current exploration projects will result in viable mineral production or that any of the mineralization identified to date will ultimately result in an increase in our ore reserves. Set forth below is a map of our principal exploration projects in Peru as of December 31, 2015.

Exploration Projects in Non-Operating Areas

Tambomayo. The Tambomayo project is located 50 kilometers southeast of the Orcopampa mine and includes a total of 1,600 hectares of mining properties. This project is a low sulfidation epithermal deposit with significant gold and silver mineralization in veins. As of December 31, 2015, we had estimated resources of 1.08 million tons, with 9.4 grams per ton of gold, 9.3 ounces per ton of silver, 2.0% lead and 3.0% zinc. In addition, we had estimated a non-reserve mineralization (“NRM”) of 0.77 million tons, with 9.6 grams per ton of gold, 4.1 ounces per ton of silver, 1.8% lead and 3.3 percent zinc. The project is currently in its development phase, and the construction of the mine is well advanced with seven levels completed and with encouraging drill intercepts at lower levels. Construction permits were granted in June 2015 for a 1,500 tons-per-day plant. In 2016, we will focus our exploration efforts in the Mayra and Gaby prospects. We plan to invest US$1.39 million to conduct geological mapping and sampling. In addition, we expect to obtain environmental permits and surface rights for a drilling campaign at the Asuncion vein.

San Gabriel. San Gabriel is located in the region of Moquegua and is wholly-owned by Buenaventura. This deposit is an intermediate sulfidation deposit hosted by diatreme breccia body at the sediment-intrusive contact. As of December 31, 2015 we estimated a NRM of 12.25 million tons, with an average grade of 6.5 grams per ton of gold. We began using a mine ramp in June 2015 in order to explore opportunities for additional diamond drilling in the Canahuire ore body and to obtain bulk samples for metallurgical tests. In addition, we completed 3,418 meters of diamond drilling in the Pachacutec prospect without positive results. In 2016, we plan to invest US$2.69 million to conduct diamond drilling and to carry out geological mapping and sampling to define new exploration targets.

Trapiche. The Trapiche project consists of 30,591 hectares of mining concessions, with porphyry copper and skarn mineralization in the Apurimac region, Antabamba province and Juan Espinoza Medrano district. The Apurimac region is part of a mineralized belt known as the Abancay Batholith where several iron, copper and gold deposits have been identified. As of December 31, 2015, we estimated a NRM of 925 million tons for the Trapiche project, with an average grade of 0.39% of copper, 0.01% of molybdenum and 3.2 grams per ton of silver. During 2016 we expect to have a positive scoping study for a leach only alternative. We estimate there are 251 million tons of leachable material with an average grade of 0.54% copper in the project.

Pisaccalla. The Pisaccalla project consists of 11,331 hectares of mining concessions located in the Ayacucho region in southern Peru and is wholly-owned by Buenaventura. In 2015, we explored 822 meters of the Accocuruz project through diamond drilling without positive results. We do not plan to conduct any further work in this project and all exploratory surface work has been remediated. On the other hand, in the geological mapping and sampling for the Ccelloccasa project, we identified 5.33 kilometers of outcropping veins with encouraging results. During 2016, we plan to carry out a geophysical survey and obtain the necessary environmental and social permits in order to conduct a drilling campaign in 2017.

Livitaca. The Livitaca project is located in the Cusco region in southern Peru, 8 kilometers north of the Constancia copper project owned by Hudbay. The project consists of 9,095 hectares of mining concessions owned by Corporación Aceros Arequipa S.A., which has leased those hectares to Cía. de Minas Cerro Hablador S.A.C., our newly formed wholly-owned subsidiary. The project is an iron skarn with surrounding gold and copper mineralization. In 2015, we determined that the project does not have adequate potential. We do not plan to carry out any additional work at this project.

Palla Palla. Palla Palla is located in the Ayacucho region. The property consists in 6,894 hectares of mining concessions owned by Cia. de Minas Caudalosa S.A., which has leased those hectares to Minera Azola S.A.C., our wholly-owned subsidiary. We are working to obtain the environmental permit needed to execute a diamond drilling campaign of 4,000 meters at the Cerro Runtus project during the second half of 2016.

San Gregorio. The drilling program at this project continues to be suspended due to the opposition of the Vicco community. We have resumed discussions with the community and, due to the active participation of the Conflict Resolution Office, an entity operating under the auspices of the Presidencia del Consejo de Ministros (“PCM”), in such discussions, we expect to resume the drilling program at this project.

Exploration in Operating Areas

Uchucchacua. We are currently focusing our exploration efforts on the Yumpag project, which is located four kilometers northeast of the Uchucchacua mine. The project is an epithermal silver deposit, structurally influenced by the Cachipampa fault. This fault also influences significant areas of silver mineralization at the Uchucchacua mine. During 2015, we invested US$3.63 million and completed 8,398 meters of diamond drilling and conducted metallurgical tests with encouraging results. As of December 31, 2015 we estimated NRM of 0.63 million tons, with 26.3 ounces per ton of silver, 0.5% lead, 1.3% zinc and 19.3% manganese. In 2016, we expect to invest US$2.30 million in order to conduct 8,000 meters of diamond drilling at this project.

Orcopampa. During 2015, our main exploration focus was in the Pucay project, located 3.5 kilometers southwest of the Chipmo mine. This project consists of 2,400 hectares of mining concessions owned by SCCO, which leased those hectares to Apu Coropuna S.R.L., our newly formed wholly-owned subsidiary. In Pucay, we focused on the Anquicha project, which shows encouraging results of epithermal gold mineralization in sandstone-hosted oxidized fractures and breccias. Preliminary column leach tests show gold recoveries of around 89%. In 2016, we will continue geological mapping and sampling at the Anquicha and Huiscatori projects.

The Alejandra - La Zanja. In April 2015, we ceased underground explorations in the Alejandra vein. As of December 31, 2015, we estimated a NRM of 0.22 million tons, with 10.4 grams per ton of gold and 170 grams per ton of silver. Additionally, we invested US$6.6 million to conduct geological mapping, sampling and a geophysical survey in the northeast extension of the Alejandra trend, which allowed us to identify a series of echelon epithermal veins with encouraging values in gold and silver. We expect to invest US$1.5 million in order to conduct 5,000 meters of diamond drilling in the second quarter of 2016.

Competition

We believe that competition in the metals market is based primarily upon cost. We also compete with other mining companies and private individuals for the acquisition of mining concessions and leases in Peru and for the recruitment and retention of qualified employees.

Sales of Metal Concentrates

All of our metal production is sold to smelters, traders and banks, either in concentrate or metal form, such as gold-silver concentrate, silver-lead concentrate, zinc concentrate, lead-gold-copper concentrate and gold and silver bullion. Our concentrates sales are made under one- to three-year, U.S. Dollar-denominated contracts, pursuant to which the selling price is based on world metal prices as follows: generally, in the case of gold and silver-based concentrates, the London Spot settlement prices for gold, less certain allowances, and the London Spot or the United States Commodities Exchange settlement price for silver, less certain allowances; and, in the case of base-metal concentrates, such as zinc, lead and copper, the London Metals Exchange (“LME”) settlement prices for the specific metal, less certain allowances. Sales prices vary according to formulas that take into account agreed contractual average prices for a quotational period, generally being the month of, the month before, or the month following the scheduled month of shipment or delivery according to the terms of the contracts.

The historical average annual prices for gold and silver per ounce and our average annual gold and silver prices per ounce for each of the last five years are set forth below:

|  | Gold |  |  | Silver |
|  | Average Annual Market Price |  |  | Our Average Annual Price(1) |  |  | Average Annual Market Price |  |  | Our Average Annual Price(1) |
|  | US$/oz.(2) |  |  | US$/oz. |  |  | US$/oz.(3) |  |  | US$/oz. |

2015 |  |  | 1,218.45 |  |  |  | 1,151.44 |  |  |  | 16.71 |  |  |  | 15.06 |
2016 (through March 31, 2016) |  |  | 1,182.56 |  |  |  | 1,107.87 |  |  |  | 14.85 |  |  |  | 13.34 |

| (1) | Our average annual price includes only the consolidated average annual price from our mines.

| (2) | Average annual gold prices are based on the London PM fix as provided by Metals Week.

| (3) | Average annual silver prices are based on London Spot prices.

| 26 |

Most of the sales contracts we enter into with our customers state a specific amount of metal or concentrate the customer will purchase. We have sales commitments from various parties for nearly all of our estimated 2016 production; however, concentrates not sold under any of our contracts may be sold on a spot sale basis to merchants and consumers.

Note: The price of the concentrate supplied under the contract is based on specified market quotations minus deductions.

We also sell refined gold, which is derived from our operations at Orcopampa, Breapampa, Coimoloache and La Zanja and processed at a local smelter in Lima, to Johnson Matthey Public Limited Company, or Johnson Matthey, which further refines the gold. During 2015, the price of the gold supplied was determined based on, for the gold content, the quotation for gold at the London Gold Market PM fixing in U.S. Dollars, and for the silver content, the quotation for silver at the London Silver Market spot fixing in U.S. Dollars or at spot prices, minus, in each case, certain minimum charges, as well as charges for customs clearance and treatment of the gold (which varies depending on its gold and silver content). We may elect to have our material toll refined at Johnson Matthey’s Brampton, Canada works and returned to our account for sale to third parties. Pursuant to our agreement, we are responsible for delivering the gold to Johnson Matthey’s designated flight at the Lima airport.

Hedging/Normal Sales Contracts

We and our wholly-owned subsidiaries are completely unhedged as to the prices at which our gold and silver will be sold. See “Item 3. Key Information—D. Risk Factors—Factors Relating to the Company—Our financial performance is highly dependent on the prices of gold, silver, copper and other metals.”

El Brocal uses derivative instruments to manage its exposure to changes in the price of metals. Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

El Brocal’s hedge is classified as a cash flow hedge. The effective portion of gain or loss on the hedging instrument is initially recognized in the consolidated statements of changes in equity, under the caption other equity reserves, while the ineffective portion is recognized immediately in the consolidated statements of profit or loss in the interest expense caption. Yanacocha and Cerro Verde have not engaged in, and are currently not engaged in, gold or copper price hedging activities, such as forward sales or option contracts, to minimize their respective exposures to fluctuations in the price of gold and copper. El Brocal had no outstanding hedging commitments in 2015.

Regulatory Framework

Mining and Processing Concessions

In Peru, as in many other countries, while surface land is owned by private landowners, the government retains ownership of all subsurface land and mineral resources. Our right to explore, extract, process and/or produce silver, gold and other metals is granted by the Peruvian government in the form of mining and processing concessions. The rights and obligations of holders of mining concessions, provisional permits and processing concessions are currently set forth in the General Mining Law (Single Unified Text approved by Supreme Decree 014-92-EM), which is administered by the MEM.

Pursuant to the General Mining Law, filers of mining claims must obtain a mining concession before they may explore the areas claimed. Applications for mining concessions must be filed with the regional mining directors of each regional government and with Instituto Geológico Minero y Metalúrgico the Geological, Mining and Metallurgical Institute of Peru (“INGEMMET”).

Mining concessions are irrevocable, provided the holder of a mining concession complies with the obligations set forth in the General Mining Law. Such concessions have an indefinite term, subject to payment of an annual concession fee per hectare claimed and achievement of minimum annual production for each hectare. Failure to achieve annual production targets will result in a fine. Failure to pay concession fees or fines for two consecutive years could result in the loss of one or more of the mining rights. Failure to satisfy minimum annual production thresholds for a specified period of time could result in cancellation of the concessions.

| 28 |

Our and Yanacocha’s processing concessions enjoy the same duration and tenure as our mining rights, subject to payment of a fee based on nominal capacity for the applicable processing plant. Failure to pay processing fees or fines for two consecutive years could result in the loss of the processing concessions.

Our mining rights and processing concessions are in full force and effect under applicable Peruvian laws. We believe that we are in compliance with all material terms and requirements applicable to the mining rights and processing concessions and that we are not subject to any condition, occurrence or event that would cause the revocation, cancellation, lapse, expiration or termination thereof, except that we may, from time to time, allow to lapse, revoke, cancel or terminate mining rights and processing concessions that are not material to the conduct of our business.

In addition to obtaining mining rights from the Peruvian government, applicable Peruvian regulations require us to obtain easements or other rights from private landowners that own the surface land above the mineral resources that we intend to explore or mine. Supreme Decree 020-2008-EM requires us to obtain such easements or other rights before commencing exploration activities. We have been actively seeking to acquire land surface, easements to land containing prospective geological exploration target sites, deposits that can be exploited in the future and areas suitable as plant or facility sites. In the case of processing concessions, article 35 of Supreme Decree Nº 018-92-EM, as amended, requires holders of such concessions to own the land underlying the concession or to have the authorization of the owner of the land.

The Law Regulating Mining Concessions in Urban Areas and Urban Expansion Areas and related regulations set forth procedures for the granting of mining rights in urban and urban expansion areas. To grant a mining concession in an urban expansion area, the MEM is required to receive the approval of the council of the applicable provincial municipality. The council has sixty days to issue its decision. Mining concessions in urban expansion areas are granted for 10-year terms, which may be renewed by the MEM subject to the approval of municipal authorities, but cannot exceed 100 hectares.

Law No. 28964, which became effective on January 25, 2007, created the Organismo Supervisor de la Inversión en Energía y Minería (“OSINERGMIN”) as the government agency in charge of regulating and auditing the electricity, hydrocarbon and mining activities of companies. Law No. 28964 provides that the overview and audit of activities related to the environment, mining safety and health regulations may be performed by companies duly certified and approved by OSINERGMIN. However, pursuant to Supreme Decree 001-2010-MINAM, OSINERGMIN has transferred its environmental supervisory functions to the Environmental Evaluation and Oversight Agency, (“OEFA”). Beginning July 22, 2010, OEFA assumed the authority to carry out unexpected audits and levy fines on companies if they fail to comply with prescribed environmental standards. Contributions that mining companies are required to make to OSINERGMIN were approved by Supreme Decree No. 128-2013-PCM and contributions required to be made to OEFA by Supreme Decree No. 130-2013-PCM.

With respect to employee safety and employer liability, Law No. 28964 has been replaced by Law No. 29783. Such employee safety and employer liability and related matters are audited by the Ministerio de Trabajo y Promoción del Empleo. Law No. 29783, as amended by Law No. 30222, establishes the minimum rules designed to prevent employee safety risks and allocate liabilities in relation to such risks. The main principle of this law is that the employer assumes the economic, legal and any other type of liability arising from accidents or diseases suffered by the employee while working, and guarantees the employee’s health and safety in connection with the employee’s work. This legislation entitles labor inspectors to inspect commercial facilities and, under certain circumstances, suspend operations. Such law amended the relevant provision of the criminal code, which currently establishes that a person who intentionally breaches the safety and health provisions, and who after being required by the relevant authority, does not adopt the measures contemplated in such provisions, is deemed to jeopardize the life, health or physical integrity of such person’s employees and may be held criminally liable for such behavior.

Environmental Matters

In 2005, Peru enacted the General Environmental Law (Law No. 28611), which establishes the main environmental guidelines and principles applicable in Peru. Pursuant to the General Environmental Law, the Ministry of the Environment (“MINAM”) issued national environmental standards, which have gradually replaced prior guidelines governing governmental agencies environmental competencies. OEFA has the authority to inspect mining operations and fine companies that fail to comply with prescribed environmental standards.

Each mining company that began operations before May 1993 was required to file a Preliminary Environmental Evaluation, (“EVAP”), for each of its mining units to disclose any pollution problems in its operations and, thereafter, to submit a follow-up Programa de Adecuación y Manejo Ambiental (“PAMA”) aimed at implementing measures to solve problems identified in the EVAP. Companies must correct the pollution problems relating to their mining activities within five years, while smelters must take corrective measures within ten years. These companies must allocate funds in an amount corresponding to no less than 1% of their annual sales to redress the problems identified in their EVAPs and contemplated in their PAMAs.

In addition, the MEM has issued regulations that establish maximum permissible levels (“LMP”) of (i) emissions of liquid effluents and (ii) elements and compounds present in gaseous emissions resulting from the mining activities. Generally, mining rights holders and processing plants that were in operation before May 1993 were required to comply with LMP within 10 years. In the meantime, mining operators are required to prepare Environmental Adaptation and Management Programs, or PAMAs, that set forth plans to ensure compliance with more stringent LMP.

In May 2008, the Ministry of Environment was established by legislative decree. The principal functions of the Ministry of Environment include formulating and implementing policies and regulations relating to environmental matters and controlling pollution, including regulating air and water quality standards, through supervision and education.

In 2008 and 2010, the Ministry of Environment enacted new water quality standards and new LMP for liquid effluents. In 2009, all Peruvian mining companies were required to submit updated environmental management plans to the MEM that complied with water quality standards and new LMP for liquid effluents. At the end of 2015, Supreme Decree No. 015-2015 - MINAM (the “2015 Decree”) was published, which modified the water quality standards and established supplementary provisions related to compliance.

Under the 2015 Decree, mining companies must incorporate new water quality standards into affected environmental management plans by (1) where the MEM has already approved such plan, submitting an updated plan or (2) where the MEM is currently evaluating a plan, submitting a modified plan. The Company plans to submit updated and modified plans to the MEM as required by the 2015 Decree.

On March 26, 2013, Supreme Decree No. 002-2014-MINAM became effective. It approves the Environmental Quality Standards (Estándares de Calidad Ambiental) (“ECA”) for soils, or “Standards,” which are applicable to any project or activity that may generate an environmental risk. Subsequently, on March 25, 2014, supplementary provisions for the application of the Standards were approved through Supreme Decree No. 002-2014-MINAM. Operations of projects existing at that time were required to submit the first phase of soil characterization within twelve months of the passage of the decree. Buenaventura and its associated companies submitted this information within the required time.

Since May 1993, new mining and processing activities have been required to file and obtain approval for an EISd before being authorized to commence operations. New mining and plant processing activities are required to comply with the LMP from the initiation of their operations. In 2009, MINEM approved the EISd for the La Zanja, Mallay, Tantahuatay and Esperanza projects. In 2010, MINEM approved the EISd for the Angélica Rublo Chico project. In 2011, the MEM approved the EISd for our Orcopampa and Breampampa projects. MINEM approved the modified EISd for the Mallay mine and the second modified EISd for the Shila cyanidation circuit in 2012. In 2014, MINEM approved the modified EISsd of Uchucchacua. In 2015, the EISd of Tambomayo was approved.

We and our subsidiaries are subject to ongoing administrative and judicial proceedings relating to environmental matters for which we have reserved contingencies of up to US$1.2 million This amount does not include loss contingencies reserved for associates accounted for under the equity method (Yanacocha, Cerro Verde and Coimolache).

In 2012, Peru enacted Supreme Decree No. 020-2012-EM, which added Chapter XVII to the Mining Proceedings Regulations approved by Supreme Decree No. 018-92-EM. The new provisions require the approval of the General Mining Directorate of the MEM or of the relevant Regional Government before proceeding to start and re-start exploration, development, preparation and exploitation.

Regulations governing mining explorations. In May 2008, the Peruvian government enacted DS 020-2008-EM, which governs mining exploration activities and related matters. Under DS 020-2008-EM, exploration activities fall into 2 categories: Category I and Category II. Category I exploration activities are those involving no more than 20 drilling platforms or affecting a surrounding area that measures less than 10 hectares in size, while Category II exploration activities are those involving more than 20 drilling platforms and affecting an area larger than 10 hectares. For Category I exploration activities, an Environmental Impact Declaration (Declaración de Impacto Ambiental) (“EID”) is required. For Category II exploration activities, a Semi-detailed EIS (Estudio de Impacto Ambiental) (“EISsd”) which is required which incorporates technical, environmental and social matters. Exploration activities must start within twelve months following the date that an EID or EISsd is approved. Both the EID and the EISsd must be approved before exploration activities begin. Any commitments assumed by mining companies in an EID or EISsd are mandatory and, if they are not fulfilled, OEFA has the authority to fine non-compliant mining companies. The regulation also provides that during exploration programs the holder of mining concessions will perform specified closure and post closure activities. In addition, fines can be imposed if exploration programs begin before the EID and the EISsd are approved, and the approval of environmental studies for exploration activities performed within protected natural areas requires the approval of the applicable water authority. Exploration in Prehispanic Archeological Sites (referred to in DS N° 004-2000-ED) is forbidden, unless expressly authorized by the National Institute of Culture.

Also in May 2008, MINEM enacted DS 028-2008 which regulated the citizen participation process within the framework of environmental permit approval. The EID and EISsd provide local communities with an opportunity to actively engage in this process.

The following EIDs and EISsd were approved in 2015:

Buenaventura

La Zanja |  | 9na Modf. EIAsd |  | RD N° 483-2015-MEM-DGAAM |  | 16 – 12 - 2015

Investment Promotion Regulations. Supreme Decree 054-2013-PCM was passed to promote investment projects. It allows companies to submit a technical report to modify ancillary components, capacity expansions, or introduce technological improvements. MINEM will then issue a compliance waiver within no more than 15 working days from the date of submission.

Regulations governing mine closures. In 2003, Law No. 28090, Ley que Regula el Cierre de Minas (Law that Regulates the Closing of Mines), established the obligations and procedures that mining companies must follow to prepare, submit and execute plans for the closing of mines, or “Closure Plans,” and the granting of environmental guarantees to secure compliance with Closure Plans. We are required to submit a Closure Plan for new projects to MINEM within one year following approval of an EIS or PAMA; inform MINEM semi-annually of any progress on the conditions established in the Closure Plan; perform the Closure Plan consistent with the schedule approved by MINEM during the life of the project; and set up an environmental guarantee that covers the estimated amount of the Closure Plan.

| 31 |

In addition, Supreme Decree No. 020-2008-EM requires mining companies that perform exploration activities to conduct certain closing activities in accordance with the applicable environmental study approved by the relevant authority, subject to deferral under certain circumstances, and contemplates a Closure Plan to be submitted by the mining company following the terms and conditions of Supreme Decree Nº 033-2005-EM.

Our Closure Plans were approved by MINEM for all of our mines and advanced explorations. To date, MINEM has approved our Closure Plans for Julcani, Recuperada, Uchucchacua, Orcopampa, Poracota, Antapite, Caravelí, Shila, Paula, Esperanza, Pozo Rico, Mallay, Trapiche, Breapampa, Angélica Rublo Chico, Anamaray-Jancapata, La Zanja, Tantahuatay and Tambomayo.

The following mine closure plan modifications were approved in 2015:

On November 9, 2009 Supreme Decree No. 078-2009-EM became effective, creating additional environmental obligations for mining concessions holders. Under this provision, mining concessions holders that performed mining activities, including mining exploration, production and processing activities or related activities, without having an Environmental Certification will be required to prepare and perform an Environmental Remediation Plan to address the environmental impact in the areas in which such activities have been conducted. Environmental Remediation Plans could only be filed once mining activities have ceased. Environmental Remediation Plans would contain a detailed description of all the mining facilities and activities performed without the correspondent Environmental Certification, including maps and related information, a detailed description of the environmental impacts created by such activities, a detailed description of the remediation actions, a detailed description of the compensation that is proposed to be made, a budget and schedule of the remediation activities, including their costs, a bond in favor of MINEM for the cost of the execution of the measures contained in the Environmental Remediation Plan. Once the Environmental Remediation Plan is completed, mining concessions holders are required to inform the auditing entity so it can verify that the actions were carried out as approved. The auditing entity is required to send the respective report to the relevant authority so that the bond may be returned.

Law No. 28271, Law that Regulates the Environmental Liabilities of Mining Activities (Ley que Regula los Pasivos Ambientales de la Actividad Minera), came into force on July 7, 2004 and serves to regulate the identification of liabilities and financial responsibility for remediation in mining activities, in each case to mitigate any negative impact mining may have with respect to the health of the population, environment and property. Pursuant to Law No. 28271, as amended by Law No. 28526 and Legislative Decree No. 1042, the technical branch of MINEM will identify environmental liabilities, mining companies responsible for abandoned mining facilities, mining works and residue deposits that may be linked to such environmental liabilities and holders of inactive mining concessions with mining liabilities. Holders of inactive mining concessions with environmental mining liabilities will be required to submit a Closure Plan and enter into environmental remediation agreements with MINEM to perform any studies and work necessary to control and mitigate the risk and effects of any contamination. Regulations under Law No. 28271, Regulations of Environmental Liabilities of Mining Activities (Reglamento de Pasivos Ambientales de la Actividad Minera), were approved by Supreme Decree No. 059-2005-EM.

| 32 |

We have presented Closure Plans to the MINEM for all our mining concessions with environmental mining liabilities. To date, the Hualchocopa, Lircay, Bella Unión-Paucaray and Chaquelle mining units have all been closed and post-closure activities at each of these units are currently underway.

On November 12, 2014, a new Environmental Protection and Management by-law was enacted, which covers mining production, processing, common labor, transport, and storage, and sets forth a new set of requirements for these activities. Going forward, social and technical teams from MINEM will accompany the collection of baseline information. Early involvement of the statutory authority throughout the environmental studies process is expected to bring about shorter approval times.

On December 28, 2015, the Servicio Nacional de Certificación Ambiental, which operates under the auspices of MINAM took responsibility for the approval of detailed EIS, submitted by private, public, or mixed-capital organizations. This development is consistent with the expansion of MINAM’s technical and regulatory capacities.

We anticipate additional laws and regulations relating to environmental matters will be enacted over time. The development of more stringent environmental regulations in Peru could impose additional constraints and additional costs on our operations, and we would be required to make significant additional capital expenditures in the future. Although we believe that we are substantially in compliance with all applicable environmental regulations of which we are now aware, there is no assurance that future legislation or regulatory developments will not have an adverse effect on our business or results of operations.

In connection with the approval of environmental studies, the Peruvian government has issued several decrees intended to simplify the issuance of permits, including Supreme Decree No. 054-2013-PCM (effective since June 2, 2013), Supreme Decree No. 060-2013-PCM (effective since May 26, 2013) and Ministerial Resolution No. 092-2014-MEM/DM (effective since May 27, 2014). We believe these provisions should facilitate the approval of environmental studies for our new exploration projects and simplify the issuance of certificates of non-existence of archeological remains required for mining projects.

Prior Consultation with Local Indigenous Communities

In 2011, Peru enacted Law No. 29785, the Law of Prior Consultation for Indigenous and Native Communities (Ley del Derecho a la Consulta Previa a los Pueblos Indígenas y Originarios, Reconocido en el Convenio 169 de la Organización Internacional del Trabajo). This law establishes a prior consultation procedure that the Peruvian government must undertake in concert with local indigenous communities whose collective rights may be directly affected by new legislative or administrative measures, including the granting of new mining concessions. Under this law, the Peruvian governmental agency responsible for issuing or approving the administrative measure or decree in question, rather than the affected local indigenous community, retains the right to approve or reject the relevant legislative or administrative matter following such consultation. However, to the extent that any of our future projects require the promulgation of legislative or administrative measures that impact local indigenous communities, the required prior consultation procedure may result in delays, additional expenses or failure to obtain approval for such new project.

Regulations under Law No. 29785 were approved by Supreme Decree No. 001-2012-MC, which became effective on April 2, 2012. These regulations specify the form and circumstances of the required consultation and the manner in which agreements will be formalized, and provide for a consultation process that lasts no more than 120 calendar days.

Permits

We believe that our mines and facilities have all necessary material permits to operate. All future exploration projects will require a variety of permits. Although we believe the permits for these projects can be obtained in a timely fashion, permitting procedures are complex, time-consuming and subject to potential regulatory delay. We cannot predict whether we will be able to renew our existing permits or whether material changes in existing permitting conditions will be imposed. Non-renewal of existing permits or the imposition of additional permitting conditions could have a material adverse effect on our financial condition or results of operations.

| 33 |

Insurance

We maintain a comprehensive insurance program designed to address specific risks associated with our operations, in addition to covering the insured risks common to major mining companies. Our insurance program is provided through the local Peruvian insurance market and includes employers’ liability, comprehensive third party general liability and comprehensive automobile liability, all risk property on a replacement basis, including transit risks, as well as business interruption insurance and mining equipment insurance.

Mining Royalties and Taxes

Under Peruvian law, holders of mining concessions are required to pay the Peruvian government a mining royalty (regalia minera) for the exploitation of metallic and non-metallic resources. In accordance with Law No. 28258, as amended by Law No. 29788, mining royalties are payable either as a specified percentage of operating profit or 1% of revenues, whichever is higher. If the mining royalty is calculated as a percentage of operating profit, marginal rates ranging from 1% to 12%, increasing progressively for companies with higher operating margins, will apply.

Mining companies that are a party to mining stabilization agreements will not be required to pay a mining royalty during the tenure of their stabilization agreements. Although we are not party to any stabilization agreements, Yanacocha currently has effective stabilization agreements for the Yanacocha, La Quinua and Maqui mines.

In addition to mining royalties, pursuant to Law No. 29789, effective from October 1, 2011, mining operations in Peru are subject to a new extraordinary mining tax. Mining companies that do not have taxation stability agreements with the Peruvian government, such as Buenaventura, will pay the “Special Mining Tax” (Impuesto Especial a la Minería). The Special Mining Tax is calculated as a percentage of operating profit. Marginal rates range from 2% to 8.4%, increasing progressively for companies with higher operating margins. Mining companies that have stability agreements with the Peruvian government will pay the “Special Mining Duty” (Gravamen Especial a la Minería). The Special Mining Duty is calculated as a percentage of operating profit, with marginal rates ranging from 4% to 13.12%, increasing progressively for companies with higher operating margins.

Safety

During 2015, we experienced 70 reportable injuries, which were comprised of 67 lost-time injuries and 3 fatal injuries, as compared to 86 total reportable injuries during 2014, which were comprised of 81 lost-time injuries and 5 fatal injuries. Under Peruvian legislation, reportable injuries include: accidental injuries resulting in lost-time, fatal accidents, accidents that require medical treatment or result in a loss of consciousness, an inability to perform all job duties on any workday after the injury or the temporary assignment or transfer to another job. Injuries involving first-aid only are not reportable as they are considered minor accidents.

The following activities and programs were implemented during 2015 in order to improve safety management system:

| · | a defensive driving course was taught to hazardous materials truck drivers;

| · | a Corporate Crisis Committee Operating Plan was developed and distributed;

| · | a compliance program was developed to minimize accidents due to rock fall, ventilation and electric shocks;

| · | a meeting with the Operations Vice President, the Business Development Vice President, Regional Operations Managers, Site Managers, Site Safety Managers and Safety Directors was held in Lima in order to improve visible leadership and further our safety system;

| · | our Operations Vice President and his team toured all sites to reinforce our safety policy;

| · | a score of 63% was achieved in the Annual General Safety Audit;

| · | the Buenaventura Integrated System was re-certified by Bureau Veritas in ISO 9001, ISO 14001 and OSHAS 18001 standards;

| · | the program “one production day without a lost time accident” became “five production days without a lost time accident,” reaching 50% effectiveness as we achieved 8 out of 16 weeks without a lost time accident; and

| · | with respect to industrial hygiene, our positions were monitored to control physical, chemical, biological, ergonomic and psychosocial hazards.

YANACOCHA

A. History and Development of the Company

Founded in Peru in 1992, Yanacocha is one of the largest gold producers in South America, having produced 917,691 ounces of gold in 2015. Yanacocha’s operations are located in the Andes Mountains in Northern Peru in the region of Cajamarca, located approximately 600 kilometers north of Lima and north of the city of Cajamarca at an altitude of 4,000 meters above sea level. The Yanacocha property consists of the following open-pit mines: Chaquicocha, Maqui Maqui, Cerro Yanacocha, La Quinua Complex (La Quinua, El Tapado, El Tapado Oeste), Cerro Negro Este, Western Oxide pits (La Quinua Sur and Cerro Negro Oeste), Eastern Oxide pits (Quecher Norte and Marleny) and Carachugo Alto.

Yanacocha also owns the Conga project, which is located approximately 24 kilometers northeast of the Yanacocha operating mine in the provinces of Celendin, Cajamarca and Hualgayoc. There was no exploration or development of new reserves because the Conga project's development and reserve balances reported in 2014 were reclassified to mineralized material in 2015.

As of December 31, 2015, Yanacocha’s proven and probable reserves (excluding the Conga project, for which reserves were reclassified as resources or NRM as of December 31, 2015) were estimated to be 5.1 million ounces of gold, representing a 4% increase over Yanacocha’s proven and probable reserves as of December 31, 2014, which were estimated to be 4.9 million ounces of gold. The Conga project’s reserves are excluded because they were reclassified due to the expiration of the current permit.

Proven and probable reserves are based on extensive drilling, sampling, mine modeling and metallurgical testing from which economic feasibility is determined. Under the Management Contract (as defined below), Newmont Mining, in conjunction with Yanacocha, calculates Yanacocha’s reserves by methods generally applied within the mining industry and in accordance with SEC Industry Guide 7. Reserves represent estimated quantities of proven and probable ore that, under present and anticipated conditions, may be economically mined and processed.

In 2015, Yanacocha produced 917,691 ounces of gold, compared to 969,944 ounces of gold produced in 2014. This decrease in gold production in 2015 as compared to 2014 was mainly attributable to:

| · | lower gold mill production (0.51 million ounces of gold produced in 2015 as compared to 0.46 million ounces of gold produced in 2014) due to lower feed grade (3.265 grams per ton in 2015 as compared to 3.871 grams per ton in 2014), lower recovery (80.2% in 2014 as compared to 83.2% in 2014) and lower throughput (6.1 million tons in 2015 as compared to 6.3 million tons in 2014) by the deep transitional campaigns; and

| · | higher leach pad production (0.41 million ounces produced in 2015 as compared to 0.33 million ounces produced in 2014) resulting from the inventory reduction campaign and increased ounce placement during the first half of 2015 (301,631 ounces in 2015 as compared to 142,946 ounces in 2014) due to increased ore mining at Yanacocha, Cerro Negro, La Quinua Sur and Tapado Oeste.

Silver production was 574,110 ounces in 2014 and 447,376 ounces in 2015. This decrease in silver production in 2015 as compared to 2014 was mainly attributable to beginning the deep transitional process with lower recovery on silver in the gold mill.

Newmont Mining owns 51.35% of Yanacocha through its wholly-owned subsidiary Newmont Second. We own 43.65% of Yanacocha through our wholly-owned subsidiary Condesa and the remaining 5% is owned by IFC. Yanacocha is managed by Newmont Peru. See “ – Management of Yanacocha – General Manager/Management Agreement.” Although Yanacocha has no fixed dividend policy, there is an understanding among the partners that the net income not required for sustaining capital expenditures or future development projects should be distributed following approval by the two major shareholders of Yanacocha, Newmont Mining and us.

| 38 |

Capital Expenditures

Yanacocha’s capital expenditures from its formation in 1992 through 2015 have related principally to:

| · | the construction of the Carachugo, Chaquicocha, Maqui Maqui, San José, Cerro Yanacocha, La Quinua Complex (La Quinua, El Tapado and Tapado Oeste), Cerro Negro Este, Western Oxide pits (La Quinua Sur and Cerro Negro Oeste), Eastern Oxide pits (Quecher Norte and Marleny) and Carachugo Alto mining operations;

| · | the construction of two plants at Carachugo and Yanacocha, each of which includes a leach solution processing facility and a smelter;

| · | the construction of the Yanacocha Gold Mill;

| · | the construction of four carbon column plants at Cerro Yanacocha and La Quinua;

| · | the acquisition of both new and used mining equipment;

| · | the construction of two dams;

| · | the construction of one agglomeration plant at La Quinua;

| · | the expansion of storage at La Quinua Tailings;

| · | the initial construction of a water treatment plant at La Quinua Tailings;

| · | the construction of gold mill tailing pipeline and equipment components; and

| · | several expansions of the leach pads located at the Carachugo, Maqui Maqui, Cerro Yanacocha, and La Quinua mining operations.

Yanacocha’s capital expenditures from its formation through December 31, 2015 amounted to approximately US$527 million, including capital expenditures of US$311 million in 2013, US$117 million in 2014 and US$96 million in 2015.

In 2015, Yanacocha’s principal capital expenditures included:

| · | US$29 million associated with the initial construction of one water treatment plant at La Quinua;

| · | US$28 million for the expansion of storage at La Quinua Tailings and the construction of the North Tailings Dump;

| · | US$14 million for equipment components;

| · | US$5 million for equipment upgrades in the Verde Bioleach Pilot Plant;

| · | US$3 million for drilling activities in the Quecher project;

| · | US$3 million for hydrogeological activities in the Western Oxides; and

| · | US$17 million for other minor projects.

Yanacocha anticipates that its capital expenditures for 2016 will be approximately US$79 million, of which it plans to use approximately US$39 million for Yanacocha laybacks, US$24 million to continue with the construction of a water treatment plant at La Quinua, and US$4 million in connection with improvements in a residual water treatment plant. The remaining capital expenditure budget has been allocated for investment in current operations. No capital will be employed at the Conga Project in 2016.

| 39 |

Yanacocha expects that it will meet its working capital, capital expenditure and exploration requirements for the next several years from internally-generated funds, cash on hand and financing from banks and financial institutions, if required. There can be no assurance that sufficient funding will be available to Yanacocha from internal or external sources to finance future working capital, capital expenditures and exploration and construction requirements, or that external funding will be available for such purposes on terms or at prices favorable to Yanacocha. A further decline in the price of gold would be reasonably likely to affect the availability of such sources of liquidity. See “Item 5. Operating and Financial Review and Prospects—Yanacocha—B. Liquidity and Capital Resources—Exploration Costs; Capital Expenditures.”

| B. | Business Overview

Description of Yanacocha’s Operations

The Yanacocha property consists of the following open-pit mines: Chaquicocha, Maqui Maqui, Cerro Yanacocha, La Quinua Complex (La Quinua, El Tapado, Tapado Oeste), Cerro Negro Este, Western Oxide pits (La Quinua Sur and Cerro Negro Oeste), Eastern Oxide pits (Quecher Norte and Marleny) and Carachugo Alto.

Leach pads are located at Carachugo (410 million ton capacity), Maqui Maqui (70 million ton capacity), Cerro Yanacocha (470 million ton capacity) and La Quinua (640 million ton capacity, including the Western Oxides). Each of these leach pads includes at least two leach solution storage ponds and storm water ponds located down gradient from each leach pad. The Cerro Yanacocha site has two additional solution ponds for the segregation of solution generated from the treatment of transition ores. A raw water pond is used both for storm containment and to store excess solution during the wet season.

Yanacocha has four processing facilities: Pampa Larga, Yanacocha Norte, La Quinua and the Yanacocha Gold Mill. The processing facilities can be used to process gold-bearing solutions from any of the leach pads through a network of solution pumping facilities located adjacent to the solution storage ponds or, in the case of the Yanacocha Gold Mill, to process high-grade gold ore to produce a gold-bearing solution for treatment at the La Quinua processing plant. The Yanacocha Gold Mill commenced operations in March 2008, and its total annual production is between 5.5 and 6.0 million dry tons. Production at the Yanacocha Gold Mill is expected to significantly impact Yanacocha’s future production capabilities, with total production measured in life-of-mine ounces at the Yanacocha Gold Mill representing 38% of the total ounces produced by Yanacocha. To balance mining production and Yanacocha Gold Mill total production capacity, Yanacocha has established ore stockpiles in which it deposits most of the ore from the pits, and feeds a small portion directly to the plant. The Yanacocha Gold Mill sources mill ore from the Yanacocha, Chaquicocha, El Tapado and Tapado Oeste pits.

Mining consists of a sequence of drilling, blasting, loading and hauling. Ore containing gold is transported from each mine to the nearest active leach pad while waste is taken to specially designed storage facilities. Ore is then leached by introducing diluted solutions of cyanide through an irrigation system placed on top of the ore. This solution percolates through the ore, dissolving gold and silver as AuCN and AgCN complexes, and results in a “pregnant” solution which drains to solution storage ponds to be transferred to the nearest recovery facility. The end product is doré bars comprised of approximately 65-66% gold and approximately 29% silver. The doré bars are transported from the processing plant by an outside security firm to be refined outside of Peru. See “—Transportation and Refining.” The solution from which the gold is removed (barren solution) is recycled to the leach pads for further heap-leaching after having been reconstituted with cyanide. The leaching process is generally a closed system. However, during periods of high rainfall, excess water must be treated at the facilities located at Yanacocha Norte and Pampa Larga, which have been designed to meet or exceed standards for drinking water and for agriculture and livestock as set out by the Peruvian Ministry of Health, the U.S. Environmental Protection Agency, the State of Nevada Regulations and World Bank guidelines. See “Regulation, Permit and Environmental Matters.”

Since 1997, the energy and power supply for Yanacocha has been obtained from the Peruvian national electricity system through a 220 kilovolt (“kV”) transmission line from the Trujillo-Norte substation in Trujillo to the Cajamarca-Norte substation in Cajamarca. This transmission line is owned by Consorcio Energético Huancavelica–CONEHUA, and has a design capacity of approximately 150MW.

In August 2011, a new 220kV called Interandina line was brought online from Carhuamayo-Paracsha–Conococha-Kiman Ayllu (Huallanca) and connected to the Cajamarca-Norte substation. This line belongs to Abengoa and provides Yanacocha with energy and power, leaving the old transmission line with the energy flow to Trujillo.

Minera Yanacocha also has a 60kV double triad line and a 220kV simple triad line. Both are connected to Cajamarca-Norte Substation for the direct supply of its process plants.

Alternatively, in case of emergency, reduced supply or other event affecting the national electrical system, Yanacocha has its own power generators with a capacity of approximately 27MW. This system allows the Company to maintain the sustainability of its operation system and reduce its operational risks.

In connection with a bidding process carried out during 2014, the supply of energy and power for the period from 2015 to 2018 was awarded to Duke Energy (Egenor), which is expected to achieve reductions in energy prices and result in savings of over US$25 million during the four-year term of the contract.

In 2015, Yanacocha’s power consumption was approximately 469 Giga Watt Hours at a cost of US$28.46 million. The maximum demand was 63.3MW in July 2015. See “Item 5. Operating and Financial Review and Prospects.”

Water for Yanacocha’s operations is collected from rainfall and wells. All excess water used by Yanacocha undergoes treatment at the facilities described above.

Set forth below are certain unaudited operating data for the years shown for each of Yanacocha’s mining operations that were then in operation:

Exploration

Yanacocha’s mining activities encompass 219,533 hectares, which are covered by 328 mining concessions and applications. Of these 219,533 hectares, Chaupiloma holds the mining rights related to 102,803 hectares, which are covered by 138 mining concessions. Yanacocha holds the mining rights related to 116,730 hectares underlying 190 concessions.

| 41 |

Chaupiloma has assigned these mining concessions to Yanacocha pursuant to several assignments of mining rights, each with an initial term of 20 years and one agreement with an extension of 17 years, which are renewable at Yanacocha’s request for additional 17, 20 or 30-year terms, as the case may be.

Yanacocha has four processing concessions from the MEM for its processing plants: Cerro Yanacocha (Yanacocha Gold Mill, Cerro Negro, La Quinua and Yanacocha), Yanacocha (Carachugo and Pampa Larga) and China Linda (non-metallic). The processing concessions have indefinite terms, subject to the payment of an annual fee based on nominal capacity for the processing plant. These four processing concessions include the Conga project, which is in the process of being granted.

Advanced exploration and early-stage development expenditures for the Yanacocha District during 2015 totaled US$64.2 million as compared to US$8.9 million in 2014. Expenditures focused on oxide development and advanced exploration projects which included:

| · | reserve and resource infill drilling on the Quecher Main deposit;

| · | reserve conversion infill drilling on the Los Pinos layback at Yanacocha Sur;

| · | advanced exploration at the Marleny target;

| · | development support on the Verde Bioleach Demonstration Facility; and

| · | exploration drilling in the Antonio and Tapado deposits.

During 2016, Yanacocha expects focus on continuing exploration activities in the Yanacocha district and conducting an exploration program in the Yanacocha concession block outside of its area of operations.

Yanacocha’s exploration expenditures include all of the costs associated with exploration activities such as drilling and geological and metallurgical testing. In addition, exploration costs cover engineering and project development costs on advanced stage projects. Yanacocha prepares a budget annually and allocates an amount for exploration activities based on specific projects or regions.

Yanacocha intends to continue developing other oxide and sulfide projects over the next several years, while continuing to explore the remainder of the Yanacocha district along with the adjacent Solitario mineral holdings. The Conga project currently consists of two gold-copper porphyry deposits. The Conga project is located approximately 24 kilometers northeast of Yanacocha’s operating mine in the provinces of Celendin, Cajamarca and Hualgayoc. This project, incorporated into reserves beginning in 2004 and 2005, reported 12.6 million ounces of gold reserves and 3.3 billion pounds of copper reserves as of December 31, 2015.

For 2016, Yanacocha estimates expenditures of US$3.5 million for exploration, and an additional US$4.41 million related to reserve delineation, characterization and sterilization activities for ore bodies that are currently classified as reserves. Both expenditure estimates are exclusive of significant development engineering charges. This budgeted amount will be expended mainly on oxide reserve conversion, extension drilling of known near-surface oxide inventories, sulfide exploration and early stage development within the Yanacocha district.

As of December 31, 2015, the Yanacocha district’s proven and probable reserves (excluding the Conga project’s proven and probable reserves) were estimated to be 5.1 million ounces of gold, a 4 percent increase from the Yanacocha district’s proven and probable reserves as of December 31, 2014, which were estimated to be 4.9 million ounces of gold.

As of December 31, 2015, proven and probable gold reserves were calculated using a gold price assumption of US$1,200 per ounce.

Transportation and Refining

The doré bars produced by Yanacocha are transported to refineries outside of Peru and, as a result, Yanacocha has entered into pre-established transportation contracts. Yanacocha has engaged Hermes Transportes Blindados S.A., or “Hermes,” to service its local transportation requirements. Under the terms of Yanacocha’s agreement with Hermes, the risk of loss with respect to the doré bars is assumed in its entirety by Hermes during the transportation of the doré bars from the mines to Jorge Chávez Airport in Lima. Thereafter, the responsibility for the doré bars shifts to the refiner, which has entered into a contract with an outside security firm to provide offshore transportation. The doré bars are melted, weighed and sampled in refineries abroad, which store the doré bars in strong-room vaults and assume responsibility there for the doré bars. Yanacocha pays a predetermined fee for the refining service. The final output from refineries, known as London Good Delivery gold and silver, is credited to Yanacocha’s London bullion accounts until transferred to purchasers.

Sales of Gold

Yanacocha’s gold sales are made through a monthly open-bidding process in which Yanacocha auctions its production corresponding to the next four to five weeks. This bidding process is set up by Yanacocha with approximately 10 financial institutions and trading firms before each month. Yanacocha collects bids and confirms sales. The gold is typically sold on the date of departure from Jorge Chávez Airport in Lima. If a portion of gold remains unsold, it is sold on the spot market within a few days. Silver is sold on the spot market approximately once a month to financial institutions or trading firms. The cash from such sales is received into a collection account in London against orders to the London bullion bank for deliveries of the gold and silver to the purchasers.

Delivery is made once a week and payments are collected on the day of confirmation. The payment price for the gold consists of either (i) the market price at the confirmation of the sale, or (ii) the average London PM fixing price over the tendered period plus a small premium established pursuant to the bidding process. Since 1994, Yanacocha has consistently sold to five or six financial institutions and trading firms at each auction. Such buyers are market makers and active participants in precious metal markets.

Employees

As of December 31, 2015, Yanacocha had 1,745 employees. The compensation granted by Yanacocha to its employees includes a base salary and other non-cash benefits such as a health program and life insurance. Additionally, according to the profit sharing plan required by Peruvian labor laws, Yanacocha employees have the right to receive 8% of Yanacocha’s annual profits before taxes. Fifty percent of these profits must be distributed in proportion to the number of days each employee worked during the previous year, and the remaining 50% of such profits must be distributed according to each employee’s total annual salary.

Yanacocha has agreements with independent contractors that are responsible for the security services and staffing for the execution of the Company’s projects in compliance with applicable legal regulations. As of December 31, 2015, independent contractors had hired 4,239 persons who were working in the Company’s operations, including the Conga Project.

In 2004, Yanacocha signed its first collective bargaining agreement with a union representing certain of its employees, which was created on December 9, 2003. In 2012, a new union was established. During 2013, direct collective bargaining agreements were signed with both unions for a three-year period (2013-2016). The Labor Relations Department meets with union leaders on a monthly basis to address various subjects and concerns in order to promote the creation of a productive and harmonious work environment. The parties resolve their differences through open and transparent talks. In 2016, we expect to begin negotiating an extension of the collective bargaining agreement with the two existing unions for the following period.

In order to strengthen the relations and communication process with its employees, Yanacocha’s upper management held about four face-to-face meetings with important Yanacocha stake-holders, where they had the opportunity to listen to the business plans and operating results, as well as to raise their concerns and make suggestions.

During 2015, key development programs have been implemented in order to increase technical, leadership and management skills based on talent management analysis process at all levels in our employee population. The total number of training hours in 2015 was 161,458. One program was the First Line Supervisor Program held for 216 individual collaborators and supervisors with the support of Adolfo Ibanez University. Additionally 43 managers and superintendents attended the “Talent Management during Change Environment” run by CEB Valtera.

| 43 |

Yanacocha offers its employees opportunities to collaborate, innovate and succeed in their careers. Its employee performance assessment system is associated with Yanacocha’s core values and measures its employees’ performance from a social responsibility, relationship management and leadership point of view. The work culture encompasses diversity, interacts with employees, encourages environmental and social responsibility, rewards outstanding performance and tries to develop great leaders at all levels.

Social Development

Since its creation, Yanacocha has focused on its relationship with the community and actively participating in its development. Since 1993, Yanacocha has invested US$444 million in social development programs including education, health, social infrastructure (schools and medical posts), productive infrastructure projects, rural electrification, roads, business promotion programs, local tourism programs and agricultural assistance programs.

Despite significant social investment, in recent years Yanacocha has experienced several conflicts that in some cases have affected the normal course of its operations. As a result of these conflicts, Yanacocha has increased its efforts to listen to and address the concerns and expectations of the local population.

To this end, in 2014 Yanacocha began implementing the legitimacy approach in its community engagement with a special emphasis on the following aspects: respect for Cajamarca, transparency and credibility, responsibility for water and environmental care and being a partner for development. Yanacocha believes this new engagement approach has been recognized by the community as a sign of positive change in Yanacocha.

During 2015, Yanacocha invested a total of US$5.25 million on social matters, US$4.61 million of which (including Conga Project and the Association Los Andes of Cajamarca - ALAC) were invested mainly in farming activities, the promotion of community capabilities, education and public infrastructure. Additionally, Yanacocha invested US$0.64 million in the mitigation of mining’s social impacts in its areas of operation and implemented agricultural and livestock projects, irrigation infrastructure, social development projects and the fulfillment of pending commitments with surrounding communities.

In addition, in 2015 Yanacocha invested US$2.38 million in contributions for social investment through the Cajamarca Mining Solidarity Fund. Also, Yanacocha has invested US$1.57 million on maintenance of the Kuntur Wasi road.

During 2016 Yanacocha will be focused on further improving its relationship with local communities and maximizing the value and recognition of its social investment to ensure the viability and legitimacy of its activities.

Security

Yanacocha has 11 security employees on its payroll, including five employees responsible for the security of the region as a whole. In addition, Yanacocha has a contracted security force of over 288 persons assigned to rotating shifts at its mines, its Lima offices and the city of Cajamarca. The Conga project has a total of 92 contracted security personnel responsible for patrolling and providing security to the project in rotating shifts.

None of Yanacocha’s employees, properties or headquarters was the target of terrorist incidents during 2015.

Mining and Processing Concessions

Yanacocha believes that the mining concessions assigned to it are in full force and effect under applicable Peruvian laws and that it is in compliance with all material terms and requirements applicable to these mining concessions. To the best of its knowledge, Yanacocha is not subject to any condition, occurrence or event that would cause the revocation, cancellation, lapse, expiration or termination of any of its concessions, except that Yanacocha and Chaupiloma may, from time to time, remake, cancel, terminate or allow to lapse mining concessions assigned to Yanacocha that are not material to the conduct of Yanacocha’s business.

Yanacocha has been actively pursuing the acquisition of the land surface rights or obtaining easements relating to land positions containing prospective geological exploration target sites, deposits that can be developed in the future or areas that would be considered for plant or facility sites. To date, Yanacocha has acquired all the surface rights with respect to 24,685.32 hectares of the surface land covering its Carachugo, Chaquicocha, Maqui Maqui, Haussing, Laboratorio, Línea de Alta Tensión, Presas, Sorpresa Mishacocha, San José, Cerro Yanacocha, Las Lagunas, the Conga project, China Linda, Amaro, Chasu, Solitario, La Carpa, Canjes and La Quinua (which includes the Cerro Negro deposit) mining operations, and a majority of the Cerro Quilish deposit and Calera China Linda.

| 44 |

In addition, as of December 31, 2015, Yanacocha had acquired 24,685.32 hectares, including 5,800.88 hectares of surface rights with respect to the Conga deposit, 3,588.25 hectares for Carachugo/San José/Chaquicocha, 2,153.84 hectares for Yanacocha and 1,649.94 hectares for Quilish. During 2015, the Company did not acquire any hectares. See “Yanacocha – A. History and Development of the Company.”

Regulation, Permit and Environmental Matters

Yanacocha is subject to a full range of governmental regulation and supervision generally applicable to companies engaged in business in Peru, including mining laws, labor laws, social security laws, public health, consumer protection laws, environmental laws, securities laws and antitrust laws. See “– Buenaventura – B. Business Overview – Regulatory Framework – Mining and Processing Concessions” and “– Buenaventura – B. Business Overview – Regulatory Framework – Environmental Matters” for a general description of Peruvian regulations of mining companies and environmental obligations. See “—Mining and Processing Concessions” above for a discussion of Peruvian regulations relating to the mining and processing concessions utilized by Yanacocha in its mining operations.

Yanacocha is required to submit technical documentation with respect to its mining and operations plans for the review and approval of various Peruvian government entities, including the MEM, the Ministry of Agriculture, the National and the Local Water Authorities, and the Ministry of Health. Yanacocha is required to file and obtain approval of an EIS with a Benefit Concession and Mining Permit for each of its mining operations before being authorized to operate. The EIS for the Carachugo, Maqui Maqui, San José, Cerro Yanacocha, La Quinua (including Cerro Negro) mining operations and China Linda lime plant have been reviewed and approved. Pursuant to current Peruvian regulations, Yanacocha also submits supplemental EISs each time a project’s production rate or disturbed area used is expanded. In 2006, Yanacocha filed an EIS modification to expand its operations at Yanacocha with the Supplemental Environmental Impact Assessment East (“SYE”) and in the vicinity of La Quinua with the Supplemental Environmental Impact Assessment West (“SYO”). Since 2006, two additional modifications have been submitted and approved for the original supplemental SYE EIS and one additional modification has been submitted and approved for the original supplemental SYO EIS.

The improved permit application processing times by most of the regulatory authorities observed since the third quarter of 2013 continued into 2015. A total of 31 permits of different types were approved at Yanacocha and another four permits, mainly related to environmental controls, were approved for the Conga project. The approvals of greatest significance in 2015 were a group of several minor modifications to the existing EIS pursued through Informes Técnicos Sustentatorios (“ITS”) for the components of Marleny Open Pit, Bioleaching Plant, China Linda and Water Treatement Plant LQ. The Beneficiation Concession Permits that were approved included the construction of the north TSF phase 1 LQ, the construction of Water Treatment Plant LQ and operation of 10 hectares of the leach pad 8A LQ. ITS for exploration of the projects of Yanacocha, San Jose 2 and Maqui Maqui were also approved, the latter includes the Chaquiocha underground project, whose modification involved the relocation of the entrance portal.

Yanacocha’s corporate policy is to operate in compliance with all applicable laws and regulations and adopt and adhere to standards that are protective of both human health and the environment at the facilities it builds and operates.

Yanacocha has informed us that its management believes that its operations are conducted in accordance with applicable laws and regulations. Audits and corrective action plans are used to assure compliance. Future exploration, expansion and new projects will require a variety of permits.

On December 20, 2015, the Ministry of Environment issued a regulation that modifies the ECA and extends the deadline for compliance. The new regulation provides 60 days to notify the authority whether the company will be able to comply with the new ECA, and a year to prepare and submit a modification of EIA – Plan Integral and a total of four years for the implementation phase.

| 45 |

During 2005, Yanacocha became a signatory to the International Cyanide Management Code, which provides specific and strict standards on how to manage cyanide. The required audit process was completed in September 2007 and certification under the International Cyanide Management Code occurred during April 2008. Yanacocha commissioned and successfully completed recertification audits to maintain International Cyanide Code Certification. Another Cyanide Code recertification audit was conducted in 2014 and, after having addressed the recommendations accordingly, Yanacocha was re-certified in February 2015. The Yanacocha environmental laboratory was recertified under ISO 17025 in 2015.

Yanacocha has informed us that its management believes that it is in compliance with all applicable regulations and international standards concerning safety. For the year ended December 31, 2015, Yanacocha experienced five lost time injuries, the same number of lost time injuries it experienced in 2014.

Insurance

Yanacocha maintains a comprehensive insurance program designed to address the specific risks associated with its operations, in addition to covering the normal insured risks encountered by major mining companies.

Yanacocha’s insurance program consists of a “Primary Program” and an “Umbrella/Excess Program.” Coverage under the Primary Program is provided through the local Peruvian insurance market and includes employers’ liability, comprehensive third party general liability, comprehensive automobile liability, and all risk property on a replacement basis, including transit risks, business interruption insurance and mining equipment. Coverage under the Umbrella/Excess Program is provided through Newmont Mining’s master worldwide insurance program and addresses claims that the Primary Program cannot, or will not, cover.

By-Laws of Yanacocha

Yanacocha is governed by the Peruvian Companies Law and the estatutos (the combined articles of incorporation and by-laws) of Yanacocha, or the “Yanacocha By-Laws.”

Control Over Major Corporate Events

Pursuant to the Peruvian Companies Law and the Yanacocha By-Laws (including applicable quorum requirements), without the affirmative vote of the partners of Yanacocha representing at least 51% of the voting shares, none of the following may occur:

| · | an increase or decrease in Yanacocha’s capital;

| · | the issuance of any debentures;

| · | any sale of an asset whose book value is at least 50% of the paid-in capital relating to such asset;

| · | any amendment to the Yanacocha By-Laws to change its business form;

| · | the merger, consolidation, dissolution or liquidation of Yanacocha; or

| · | any other amendment of the Yanacocha By-Laws.

Pursuant to the Shareholders Agreement among Newmont Second, Condesa, Compagnie Miniére Internationale Or S.A. and IFC, dated as of August 16, 1993, as amended by a General Amendment Letter, dated August 17, 1994, any member of the Executive Committee of Yanacocha who wishes to propose that Yanacocha’s Executive Committee authorize Yanacocha to take a Significant Action (as defined below) must (i) give written notice to each partner of such proposal before consideration thereof at a meeting of the Executive Committee and (ii) refrain from voting to approve such Significant Action until (x) the Executive Committee has received the consent of 80% of the partners of Yanacocha (a partner is deemed to have consented if no objection is received from such partner within 30 days after being notified) or (y) the Executive Committee has received the consent of at least 51% of the partners of Yanacocha and 45 days have elapsed since the member of the Executive Committee who proposed the Significant Action has responded in writing to objections received from objecting partners. “Significant Action” means:

| 46 |

| · | a disposal or sale of more than 20% by value of Yanacocha’s fixed assets;

| · | any planned shutdown or cessation of Yanacocha’s mining activities that is planned to last for more than one year;

| · | any capital expenditure by Yanacocha exceeding US$20 million;

| · | any disposal or sale by Yanacocha of the mining rights covered by certain concessions; or

| · | the approval of the construction of a project in the area owned by Yanacocha (other than the Carachugo mine and processing facilities).

Preemptive Rights

The Peruvian Companies Law and the Yanacocha By-Laws provide preemptive rights to all partners of Yanacocha. In the event of a capital increase, any partner has a preemptive right to pay its pro rata share of such increase to maintain such partner’s existing participation in Yanacocha.

In the event of a proposed transfer, exchange or sale, either voluntary or involuntary, of participation, collectively referred to as the “Offered Participation,” of one or more partners, any partner has a right to acquire the Offered Participation in proportion to its holdings of partners’ capital. If the entire partnership fails to exercise this right or some partners indicate their decision to acquire a smaller share than that to which they are entitled, the other partners will receive an increase, and consequently, the remaining participation will be distributed among them in proportion to such partners’ capital participation and within the maximum limit of the participation they have stated their intention to acquire. Finally, any Offered Participation remaining unsubscribed by the partners must first be offered to Yanacocha before they may be offered to third parties.

In addition, in the event of the occurrence of a change of control (as defined) with respect to a significant partner, or the parent of a significant partner, in Yanacocha, the other significant partner will have the right to acquire the first partner’s participation interest in Yanacocha. No change of control will occur with respect to a significant partner so long as the parent of such partner is publicly traded or if such partner’s parent is acquired, the acquiring company is publicly traded.

Legal Proceedings

For a discussion of legal proceedings, see Note 20 to the Yanacocha Financial Statements.

Other than the legal proceedings described in the Yanacocha Financial Statements, Yanacocha is also involved in certain legal proceedings arising in the normal course of its business, none of which individually or in the aggregate is material to Yanacocha or its operations.

Management of Yanacocha

Executive Committee

Pursuant to the Yanacocha By-Laws, Yanacocha’s Executive Committee consists of six members, all of whom are appointed by the partners of Yanacocha. Gary J. Goldberg, President and Chief Executive Officer of Newmont Mining Corporation, has been appointed Chairman of Yanacocha’s Executive Committee, and Roque Benavides, our President and Chief Executive Officer, serves as the Vice Chairman of Yanacocha’s Executive Committee. The Vice Chairman has the power to preside over the meetings of Yanacocha’s Executive Committee in the Chairman’s absence. The members of the Executive Committee are elected for a three-year term but may continue in their positions until the next election takes place and the newly elected members accept their positions. Alternate members are elected in the same manner as members and can act in place of and with all the authority of members when a member is unavailable, except that an alternate member may not preside over the meetings of Yanacocha’s Executive Committee. The Chairman has the right to cast the deciding vote in the event of a deadlock among Yanacocha’s Executive Committee.

| 47 |

General Manager/Management Agreement

The Yanacocha By-Laws provide that the Yanacocha Partners’ Meeting has the power to appoint and remove the Manager of Yanacocha; the Executive Committee has the power to appoint and remove other officers of Yanacocha, determine their duties and compensation and grant and revoke powers of attorney. Newmont Peru was named as Yanacocha’s Manager according to a publicly filed deed, and it continues to hold that position. Newmont Peru’s duties as Manager are defined in the Management Contract dated February 28, 1992, as amended, between Yanacocha and Newmont Peru. Pursuant to the Management Contract, Newmont Peru is responsible for managing, conducting and controlling the day-to-day operations of Yanacocha and keeping Yanacocha’s Executive Committee informed of all operations through the delivery of various written reports. The Management Contract was amended as of December 19, 2000. The amendment extends the term of the Management Contract for a period of 20 years starting at the date of amendment and provides that it may be extended for additional terms of 20 years upon request by Newmont Peru. Newmont Peru, however, may cancel the Management Contract by giving six months’ prior notice to Yanacocha. The Management Contract will be deemed terminated if, due to reasons attributable to the bad management of Yanacocha, except for reasons beyond its control, Newmont Peru is unable to substantially complete the agreed work programs. In exchange for its services as Manager, Newmont Peru receives remuneration of US$2 per ounce of gold production and its equivalent for copper production paid on a quarterly basis, which amount is expected to cover the overhead and administrative expenses for the management of the operations. Also, Newmont Peru may charge Yanacocha for the salaries of employees of Newmont Peru or its affiliates who are directly involved in the operation of Yanacocha. In 2015, Yanacocha accrued fees of US$13.3 million owed to Newmont Peru and its affiliates under the Management Contract.

Directly Operated Properties

Orcopampa

The Orcopampa mine is wholly-owned and operated by us. We lease the rights to the mining concessions of Orcopampa from a group of private investors. This lease, which expires in 2043, requires a payment from us equal to 10% of production value, subject to certain conditions. Operations started in the Orcopampa mine in 1965. In 2015, we made lease payments of US$21.9 million. We operated Orcopampa as a silver mine until the late 1990s, when we also began to mine gold-bearing veins.

The Orcopampa mine is located in the province of Castilla, department of Arequipa, approximately 1,350 kilometers southeast of the city of Lima, at an altitude between 3,800 and 4,500 meters above sea level.

The Orcopampa mine consists of an epithermal gold telluride deposit, hosted into lava flows and domes of Sarpane complex (calc-alkaline to high potassium), of early Miocene to Holocene, which forms part of the tertiary metallogenic belt of Southern Peru (Au-Ag).

Mining at Orcopampa is conducted underground using the mechanized cut-and-fill method. Mine ore is processed by the Carbon in Leach method in a plant located in Orcopampa, which was also outfitted for the treatment of old tailings. Electric power is primarily obtained from the Peruvian national electricity grid. Water for operations at Orcopampa is obtained from a lake and rivers.

Uchucchacua

The Uchucchacua mine is wholly-owned and operated by us. Operations began in 1975, and Uchucchacua is currently our largest producer of silver. Uchucchacua is located in the province of Oyón, department of Lima, approximately 265 kilometers northeast of the city of Lima at an altitude of between 4,000 and 5,000 meters above sea level.

Uchucchacua’s mineral structures are hosted by Mesozoic limestone of the Jumasha Formation and are classified as a mesothermal polymetallic deposit of silver-lead-zinc with important contents of manganese. The main mineralized structures are veins and ore bodies with high-grade silver content.

Mining at Uchucchacua is conducted underground utilizing cut-and-fill stopping, shrinkage stopping, and sublevel stopping methods. Ore is processed at a mill located at Uchucchacua. The mill has a rated capacity of 3,800 tons per day and utilizes differential flotation to obtain a lead-silver concentrate and a zinc concentrate. Electric power is obtained from the Peruvian national electricity grid, a hydroelectric plant and a diesel generator. We utilize a power line connecting Uchucchacua to the Peruvian national electricity grid and have electrical distribution facilities within the Uchucchacua mine. Water for operations at Uchucchacua is obtained from three lakes.

In December 2013, we completed construction of manganese sulfate plant Rio Seco, located 102 kilometers north of Lima. In January 2014, operations began with the treatment of manganese – silver concentrates from the Uchucchacua mine. During 2015, 24,065 tons were treated, with 144.7 ounces per ton of silver, 7.1% lead, 25.4% manganese, and following treatment 15,319 tons were obtained, with 225.0 ounces per ton of silver, 10.9% lead and 4.2% manganese. This process also allowed for the production of 14,935 tons of sulfuric acid of 98.0 percent purity and 12,880 tons of commercial grade manganese sulfate monohydrate.

Julcani

Julcani is an underground mine that is wholly-owned and operated by us. We acquired Julcani in 1953 as our first operating mine. Julcani is located in the province of Angaraes, department of Huancavelica, approximately 500 kilometers southeast of Lima at an altitude between 4,200 and 5,000 meters above sea level.

Julcani is a large polymetallic deposit in Central Peru, which principally produces silver, that occurs mainly in sulfosalts in a multitude of mineralogically complex veins in dacite domes, tuffs, breccias and other tertiary volcanic rocks.

Ore is processed by bulk flotation to obtain a concentrate of silver-lead-copper-gold. The plant has a rated capacity of 550 tons per day.

Electric power is generated by three hydroelectric plants, Huapa, Tucsipampa and El Ingenio. We are also connected to the Peruvian national electricity grid. Water for operations in Julcani is obtained from mine drainage, a stream and a small lagoon.

During 2015, we focused our exploration activities on the main mineralized structures of the Acchilla and Estela mines. In the Acchilla mine, we have begun exploration to test the deepening of silver mineralization in all main veins. We have also begun to explore for silver in an area that is adjacent to the Acchilla mine called Taype-Galindo.

Mallay

The Mallay mine is wholly-owned and operated by us and is located 21 kilometers southwest of the Uchucchacua mine in the district of Mallay, province of Oyón, department of Lima. Mallay is considered an epithermal deposit of silver, lead, zinc and gold. We have recognized the following main ore structures: Isguiz body-vein (silver, lead, zinc), Pierina (gold vein), María (silver vein) and Fortuna (skarn type lead, zinc, silver).

During 2015, we continued geological exploration with tunnels and diamond drilling mainly focused on the Isguiz body-vein and the María-Dana system silver veins. In 2016, we plan to construct exploration tunnels and conduct diamond drilling on the Nicole area in the Jumasha limestones. The San Sebastian project (2.5 kilometers northeast from Isguiz) will be explored for silver, lead and zinc with at least 3,500 meters of diamond drilling in the recognized mineralized structures by geological mapping.

As of December 31, 2015, proven and probable ore reserves were 86,446 tons, with 341.21 grams per ton of silver, 0.50 grams per ton of gold, 6.35% lead and 8.93% zinc.

Breapampa

The Breapampa mine is wholly-owned and operated by us. It is located in the district of Chumpi, province Parinacochas, department of Ayacucho. The ore deposit consists of gold and silver mineralization in an epithermal system high-sulfidation, emplaced into breccias of tertiary volcanic rocks. We located higher concentrations of gold-silver in oxides in the following geological prospects: Cerro Parccaorcco, Senccata, Pucagallo, Andrea, Ccaccapaqui, Sancos and Grace. In July 2012, we began the production phase at Cerro Parccaorcco, where gold is contained within silica-oxides.

During the productive period of Breacampa in 2014, we performed diamond drilling to update ore distribution at Parccaorcco and define the gold ore within the colluvial deposit close to the Parccaorcco open pit, where we recognized disseminated gold that is part of current reserves.

We ceased mining activities at Breapampa in November 2014. However, in 2015 we recovered 13,757 ounces of gold from the leachpads. Currently, the mine is in closure stage.

Proven and probable ore reserves at December 31, 2015 were 519,539 tons, with 17.11 grams per ton of silver and 0.44 grams per ton of gold.

La Zanja

The La Zanja mine is located in the district of Pulan, province of Santa Cruz, department of Cajamarca in northern Peru. La Zanja is located 48 kilometers northwest of the Yanacocha gold mine, at an average altitude of 3,500 meters above sea level. We hold a 53.06% interest in La Zanja and Newmont holds a 46.94% interest.

La Zanja is located within a large area of hydrothermal alteration, mainly related to epithermal gold deposits in high sulfidation environments, in addition to some vein systems of intermediate to low sulfidation. We have recognized two ore deposits: San Pedro Sur and Cerro Pampa Verde.

Mining operations are conducted through the open-pit method, the plant utilizes a carbon-in-column circuit as well as a Merrill Crowe circuit to recover gold from heap leach operations. The gold laden carbon is then transported to Yanacocha to continue processing into doré bars.

In 2013, we completed the construction of the road to Pampa Verde, which allowed us to begin open pit mining in February 2014, coinciding with the launching of the Merrill Crowe plant.

During 2015, we continued tunneling and diamond drilling exploration in the Alejandra underground project. We also continued exploring with diamond drilling in other areas around San Pedro Sur, Pampa Verde and Alejandra, such as Cocán and Campana.

Total proven and probable ore reserves at December 31, 2015 were 11,905,137 tons, with 4.04 grams per ton of silver and 0.62 grams per ton of gold.

Tantahuatay

Tantahuatay is a gold-copper mine located in the district and province of Hualgayoc, department of Cajamarca, in northern Peru, at an average altitude of 3,900 meters above sea level. The Tantahuatay mine is operated by us and wholly-owned by Coimolache, in which we hold a 40.10% equity interest.

Geologically, the Tantahuatay deposits are located at diatremes or volcanic necks in a sequence volcano-magmatic hydrothermal predominant linked to the regional mineralized sector north of Peru.

Tantahuatay consists of five areas of Au-Ag mineralization, contained in material of supergenic oxidation (Mirador Norte, Mirador Sur, Cienaga Norte, Cienaga Sur and Tantahuatay). We have also discovered that below the oxides level of the Cerro Tantahuatay area, there is a significant resource of Cu-Au-Ag in pyrite-enargite ore (sulphides), which is present as disseminations and fracture fillings associated with advanced argillic alteration and multiphase breccia bodies.

During 2015, we performed diamond drilling to update the reserves block model of the open pits Tantahuatay 2 and Ciénaga Norte and to explore the Mirador Sur, Mirador Norte, and Ciénaga Norte projects to increase mineral resources.

Total proven and probable ore reserves at December 31, 2015 were 66,196,953 tons, with 7.09 grams per ton of silver and 0.43 grams per ton of gold.

Colquijirca and Marcapunta Norte

The Colquijirca (also known as Tajo Norte) and Marcapunta Norte mines are wholly-owned by El Brocal. El Brocal was founded in 1956 and is engaged in the extraction, concentration and sale of concentrates of polymetallic minerals—mainly zinc, copper, lead and silver. Our aggregate direct and indirect equity interest in El Brocal was 54.07% at December 31, 2015.

The Colquijirca and Marcapunta Norte mines are adjacent and are located 285 kilometers east of the city of Lima and 10 kilometers south of the city of Cerro de Pasco. El Brocal produces zinc and lead/silver concentrates from the Colquijirca mine and copper concentrates from the Marcapunta Norte mine. The Colquijirca mine consists of three important polymetallic deposits: (1) Tajo Norte, which contains zinc, silver and lead ore; (2) Marcapunta, which contains an auriferous mineralization in breccia oxides and an arsenic copper enargite mineralization as a continuation of the mineralized mantles of the Marcapunta Norte mine; and (3) San Gregorio, which contains zinc.

Mining at Colquijirca is conducted through the open-pit method from which zinc and lead concentrates are produced. El Brocal’s zinc concentrate typically contains 50% zinc, while its lead concentrate contains 50% lead. Mining at Marcapunta Norte is conducted through the sublevel stopping method, from which copper concentrates are produced. El Brocal’s copper concentrates typically contains 26% copper, 4% silver and8% arsenic.

The Huaraucaca concentrator plant processes ore from both mines. In 2015, average treated ore at the plant reached 13,875 tons per day as result of increased capacity from 10,732 tons per day in the first quarter of 2015 to 16,591 tons per day in the fourth quarter of 2015 due to the completion of an expansion project. The Colquijirca mine primarily relies on a power line connected to the Peruvian national electricity grid.

El Brocal has conducted an exploration program at the Marcapunta deposit to confirm mineralization and find possible extensions, as well as to increase reserves at the Colquijirca and Marcapunta Norte mines. This program was discontinued in 2014. At the end of 2014, El Brocal obtained approval for its EIS relating to a diamond drilling program at the Marcapunta deposit.

In 2015, we invested US$24 million in tailings capacity expansion and complementary equipment for a processing plant. The construction of the expansion project operations were completed in 2014 (which, since 2008, has cost US$500 million) and reached the full expected capacity of 18,000 tons per day in December 2015. In 2015, exploration was halted in prospective areas such as San Gregorio, Marcapunta Oeste and other areas to focus efforts on increasing the crushing, milling and flotation processes to the expected capacity.

Total proven and probable reserves of Colquijirca as of December 31, 2015 were 56,200,000 tons, with 35.15 grams of silver per ton, 2.3% of zinc and 0.85% of lead. Total proven and probable reserves of Marcapunta Norte as of December 31, 2015 were 21,749,700 tons with 18.973 grams of silver per ton, 0.39 grams of gold per ton and 2.25% copper.

Reserves

We calculate our ore reserves by methods generally applied within the mining industry and in accordance with SEC Industry Guide 7. All mineral reserves are estimates of proven and probable ore quantities that under present conditions may be economically mined and processed.

The proven and probable ore reserve figures presented in this Annual Report are estimates, and no assurance can be given that the level of recovery of gold, silver and certain other metals will be realized. See “Item 3. Key Information—D. Risk Factors—Factors Relating to the Company—Estimates of proven and probable reserves are subject to uncertainties and the volume and grade of ore actually recovered may vary from our estimates.”

The term “reserves” refers to mineral deposits that could be economically and legally extracted or produced at the time of reserve determination. The term “proven reserves” means ore reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes, and grade and/or quality are computed from the results of detailed sampling, and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well established. The term “probable reserves” means ore reserves for which quantity and grade and/or quality are computed from information similar to that used for proven reserves, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation.

As of December 31, 2015, our total proven and probable reserves, including our equity share in the proven and probable reserves of El Brocal (54.07%), La Zanja (53.06%), Coimolache (40.10%) and Yanacocha (43.65%), were estimated to be 3.52 million ounces of gold, representing a 60.23% decrease compared to our total proven and probable reserves as of December 31, 2014, which were estimated to be 8.85 million ounces of gold. This decrease is primarily due to the reclassification of the Conga mine gold reserves (5.5 million ounces as of December 31, 2014) as resources or NRM as of December 31, 2015.

As of December 31, 2015, our total proven and probable reserves, including our equity share in El Brocal (54.07%), La Zanja (53.06%), Coimolache (Tantahuatay) (40.10%) and Yanacocha (43.65%), were estimated to be 139.04 million ounces of silver, representing a 17.29% decrease over our total proven and probable reserves as of December 31, 2014, which were estimated to be 168.10 million ounces of silver. This decrease is primarily due to the reclassification of the Conga mine silver reserves (37.8 million ounces as of December 31, 2014) as resources or NRM as of December 31, 2015.

The following table lists the proven and probable ore reserves as of December 31, 2015 for each of our consolidated mining operations, the Tantahuatay mine, where we have a 40.10% equity interest, the La Zanja mine, where we have a 53.06% equity interest, and the Colquijirca & Marcapunta (El Brocal) mines, where we have a 54.07% equity interest. The reserves show in the table below are the total reserves for each mine and do not reflect our equity share of reserves in non-wholly-owned mines.

Yanacocha’s Properties

Operating Properties

For operating data (including ore mined, average gold grade of ore mined and gold production) for each of Yanacocha’s operating properties and a description of how ore is processed and the source of electricity and water for each of Yanacocha’s operating properties, see “—Yanacocha—Business Overview” and “—Description of Yanacocha’s Operations.”

Carachugo – Chaquicocha

Chaquicocha Sur is an 85-hectare gold deposit (ultimate pit) which lies in the east-central part of the Yanacocha district, approximately one kilometer southeast of the mined out Carachugo deposit and 300 meters south of the Chaquicocha Norte pit. Mining at this deposit was completed in late 2015.

Carachugo is a 90-hectare gold deposit with a leach pad that covers approximately 306 hectares. Carachugo, Yanacocha’s first mine, commenced operations in August 1993. Mining was conducted by the open-pit method. The Carachugo open-pit mine ceased mining operations in 2004, although one ore processing facility remains in operation.

Maqui Maqui

Maqui Maqui is a 75-hectare gold deposit with a leach pad covering 67 hectares, located five kilometers northeast of the Carachugo pit. Mining operations at Maqui Maqui began in October 1994 and used the open-pit mining method. Although mining operations at Maqui Maqui ceased in September 2000, gold recovery from the leach pad continues. The Maqui Maqui East expansion commenced operations in 2010 and mining at this deposit was completed in late 2015.

San José

San José is a 100-hectare gold deposit, located 1.5 kilometers southwest of the Carachugo pit, that shares the leach pad located at Carachugo. Mining operations at San José began in January 1996 using the open-pit mining method. Mining operations at San José temporarily ceased during the fourth quarter of 2002 and reopened in 2005 to complete San José East. San José West started operations in early 2010 and ceased operations in November 2012.

Cerro Yanacocha

Cerro Yanacocha is a 247-hectare gold deposit (ultimate pit) with a leach pad covering approximately 310 hectares. The Cerro Yanacocha pit is located two kilometers northwest of the Carachugo pit. Operations began in the fourth quarter of 1997 using the open-pit mining method. Cerro Yanacocha includes a carbon column gold recovery plant and a Merrill-Crowe-type ore processing facility. Cerro Yanacocha temporarily ceased operations in October 2010 and restarted operations in 2015 with mining in the layback area and the deep transitional stockpiles located inside the current open pit. Mining activities are scheduled to cease by 2019.

La Quinua

La Quinua is a 450-hectare gold deposit (ultimate pit) with a leach pad covering 426 hectares. The La Quinua, El Tapado and El Tapado Oeste pits are located three kilometers southwest of the Cerro Yanacocha pit. Operations began in the fourth quarter of 2001 using the open-pit mining method. All solution processing occurs at the Cerro Yanacocha plant following treatment at the La Quinua leach pad and carbon column facility.

The La Quinua mining operation included Cerro Negro Este, a 15-hectare gold deposit (ultimate pit) which is located six kilometers southwest of the La Quinua pit. Cerro Negro Este utilized the La Quinua leach pad. Operations began in April 2004 using the open-pit mining method and all solution processing occurred at the Cerro Yanacocha plant following treatment at the La Quinua leach pad and carbon column facility. Mining operations at Cerro Negro Este ceased in March 2005.

| 60 |

Mining operations in Tapado Oeste was completed at the end of 2015, while the construction of the Tapado Oeste layback was approved in early 2015. The Tapado Oeste layback began mining operations in the first quarter of 2015.

Western Oxides

The Western Oxides are comprised of the Cerro Negro Oeste and La Quinua Sur open-pit mines. Cerro Negro Oeste, a 40-hectare gold deposit, is located 6.5 kilometers southwest of the La Quinua pit. This pit utilizes the La Quinua leach pad as its ore facility. La Quinua Sur, a 110-hectare gold deposit, is located south of the Tapado Oeste pit and is completely covered by La Quinua gravel. Mining activities started in Cerro Negro West in August 2011 and are scheduled to be finished in 2016. La Quinua Sur commenced mining activities in July 2014 and is scheduled to cease operations in 2019. The ore mined from this pit will be processed at the La Quinua leach pad expansion.

Eastern Oxides

The Eastern Oxides consist of the Marleny open-pit mine. The Marleny pit, an 8-hectare deposit, is located to the west of the Carachugo backfill. Marleny started mining operations in May 2013 and ceased operations in April 2014. Mining will restart to deepen the current pit in the first half of 2016.

Carachugo Alto

The Carachugo Alto pit, a 9-hectare deposit, is located to the east of the Carachugo backfill. Carachugo Alto commenced mining operations in July 2010, and its second phase was completed in October 2013.

China Linda

Yanacocha owns and operates the China Linda lime plant, which is located in Cajamarca, 12 kilometers to the northeast of the Yanacocha installations. Access to the plant from Yanacocha is by a ten-kilometer private, unpaved road. Lime is used in the gold and silver mining process to regulate the alkalinity of the cyanide solutions in the leaching process and for pH control in water treatment applications. Currently, the plant has a production capacity of 78,000 tons of lime per year.

Reserves

Proven and probable reserves are based on extensive drilling, sampling, mine modeling and metallurgical testing from which economic feasibility is determined. Under the Management Contract, Newmont Mining, in conjunction with Yanacocha, calculates Yanacocha’s reserves by methods generally applied within the mining industry and in accordance with SEC Industry Guide 7. Reserves represent estimated quantities of proven and probable ore that under present and anticipated conditions may be economically mined and processed.

The following table lists proven and probable reserves and the average grade of ore as of December 31, 2015 for Yanacocha. Calculations with respect to the estimates of proven and probable reserves are based on a gold price of US$1,200 per ounce and a copper price of US$2.75 per pound as of December 31, 2015. The proven and probable reserves presented below represent the total quantity of ore to be extracted from the deposits, allowing for mining efficiencies and ore dilution. Ounces of gold and pounds of copper in the districts of Yanacocha’s proven and probable reserves are calculated before any losses during metallurgical treatment.

| ǂ | Proven and probable reserves, as of December 31, 2015, were calculated using a gold price assumption of US$1,200 per ounce.

| 61 |

As of December 31, 2015, Yanacocha’s total proven and probable reserves (excluding the Conga project, the reserves for which were reclassified as resources or NRM as of December 31, 2015) were estimated to be 5.1 million ounces of gold, representing a 4% increase over Yanacocha’s total proven and probable reserves (excluding the Conga Project) as of December 31, 2014, which were estimated to be 4.9 million ounces of gold. Yanacocha’s total proven and probable reserves of copper were 3.3 billion pounds as of December 31, 2015 representing no change from of copper reserves reported as of December 31, 2014.

Based on the current recovery rate and estimated gold production levels in 2015, most of Yanacocha’s proven and probable reserves as of December 31, 2015 will be depleted by 2019 unless Yanacocha continues adding reserves to the production plan (such as the Quecher Main). Yanacocha’s management believes that its prospective land positions and mining concessions provide it with potential for future exploration and additions to its reserves.

BUENAVENTURA

Introduction

The following discussion should be read in conjunction with the Financial Statements as of December 31, 2014 and 2015 and for the years ended December 31, 2013, 2014 and 2015 and the related notes thereto included elsewhere in this Annual Report. The Financial Statements are prepared and presented in accordance with IFRS as issued by the IASB. We present our financial statements in U.S. Dollars.

| A. | Operating Results

General

Overview. We were established in 1953 and are one of Peru’s leading producers of gold, silver and other metals. Our consolidated financial statements comprise all of our accounts and those of our subsidiaries, which include:

| · | the Julcani, Mallay, Breapampa, Uchucchacua, Orcopampa, mining units;

| · | the Colquijirca, Marcapunta, and La Zanja mines, which are owned through consolidated subsidiaries;

| · | Chaupiloma, which receives a royalty payment from Yanacocha;

| 62 |

| · | Condesa, which is mainly a holding company for investments in us, Yanacocha and other affiliated mining companies;

| · | Conenhua, which is mainly engaged in the transmission of electric power to Yanacocha and other mining companies;

| · | other minor subsidiaries; and

| · | discontinued operations.

We also have material equity investments in (i) Yanacocha, which is an equity investee engaged in the exploitation and commercialization of gold, (ii) Cerro Verde, which is an equity investee engaged in the exploitation and commercialization of copper and (iii) Coimolache, which is an equity investee engaged in the exploitation and commercialization of gold and silver. We account for these investments under the equity method.

Yanacocha. Historically, a substantial part of our net loss before income tax was derived from our equity interest in Yanacocha. We have a 43.65% equity participation in Yanacocha, which is held through our wholly-owned subsidiary, Condesa. Our partnership interest in Yanacocha is accounted for under the equity method and is included under the caption “Investment in associates” on our consolidated statements of financial position. Although Yanacocha has no fixed dividend policy, there is an understanding among the partners that the net income not required for sustaining capital expenditures or future development projects should be distributed after agreement between the two major shareholders, Newmont Mining and us.

Cerro Verde. As of December 31, 2015, we had a 19.58% equity participation in Cerro Verde, which allows us to exercise significant influence over this company. As a result, we account for our investment in Cerro Verde using the equity method. Although Cerro Verde has no fixed dividend policy, there is an understanding that earnings not required for capital expenditures or future development projects are expected to be distributed.

Results of operations. The primary factors affecting our results of operations are:

| · | the amount of gold, silver, zinc and copper produced and sold by us;

| · | prevailing world market prices for gold, silver, zinc and copper;

| · | commercial terms with respect to the sale of ore concentrates; and

| · | our operating expenses.

Gold and silver price hedging. Our revenues and earnings are strongly influenced by world market prices for gold, silver, zinc and copper that fluctuate widely and over which we have no control. Depending upon the metal markets and other conditions, we may from time to time hedge our gold and silver sales to decrease our exposure to fluctuations in the prices of these metals. We and our wholly-owned subsidiaries are currently completely unhedged as to the price at which our gold and silver will be sold. As a result, we are fully exposed to the effects of changes in prevailing market prices of gold and silver.

Operating costs and expenses. Operating costs and expenses consist of:

| · | operating costs, which are direct production costs, the major component of operating expenses;

| · | exploration costs in operational mining sites;

| · | depreciation and amortization expenses;

| · | exploration costs in non-operational mining areas;

| · | administrative expenses, which principally consist of personnel expenses;

| 63 |

| · | royalties, which consist of payments to third parties and the Peruvian government to operate leased mining rights; and

| · | selling expenses, which principally consist of freight expenses.

Reserves. We utilize geological mapping, projection of ore-bearing structures, diamond drilling, core logging and chemical assaying, in addition to drifting along previously indicated mineralization, to replace and grow reserves. In addition, we use metallurgical test-work of core and bulk samples as a follow-up activity to prove the amenability of any previously indicated mineralization to certain methods available on site. We continuously analyze this information with respect to tonnage, precious-metals average grades, metallurgical recoveries and economic value and allocate funds preferentially to those projects that have the best potential to sustain or enhance profitable mine production in the near-term. Our mining operations are primarily conducted underground and consist of deposits that are difficult to explore and measure in advance of mining and in which the value or prospects for ore based on geologic evidence exceeds the value based on proved reserves throughout most of the life of mines supported by them, or extramensurate deposits.

In addition, underground mine infrastructure, such as declines, shafts and/or dewatering/ore haulage crosscuts, that facilitate access to ore reserves are constructed and categorized as mine development. We consider such underground mine infrastructure vital to assure sustainable mine production and reserve production. The design, construction and implementation of our underground mine infrastructure are presented and supervised by our Operations Manager with the Board of Directors’ approval. We capitalize mine development and mineral land costs incurred after we have identified proven and probable reserves. Upon commencement of production, we amortize these costs over the expected life of the mining area, based on proven and probable reserves and other factors.

Our other mining operations are smaller and have variable fluctuations in production and reserves due to complexities of the ore located in certain mining operations (such as the Colquijirca mine); the sale of certain mining operations (such as the Huallanca mine); partial and temporary closures of mining operations (such as the Shila-Paula and Recuperada mines); and the production of silver only as by-product of gold (such as the Orcopampa, Antapite and Shila-Paula mines).

Net income and net distributable income. Under Peruvian law, each company is required to establish a legal reserve equal to at least 20% of its paid-in capital on an unconsolidated basis. An annual contribution of at least 10% of net income must be made until such legal reserve equals 20% of paid-in capital. The legal reserve may offset losses or be capitalized. However, following any instance in which the reserve is used, Peruvian law calls for mandatory replenishment of the reserve.

Royalties. Royalty expenses consist mainly of payments made by us pursuant to lease agreements relating to mining rights for the Orcopampa mine. Specifically, we pay the lessor a royalty of 10% of the value of the concentrates produced. We are also required to pay the Peruvian government mining royalties and taxes. In addition to mining royalties, pursuant to Law No. 29789, effective October 1, 2011, mining operations in Peru are subject to a new extraordinary mining tax. See “Item 4. Information on the Company—Buenaventura—B. Business Overview—Regulatory Framework—Mining Royalties and Taxes.”

Environmental protection laws and related regulations. Our business is subject to Peruvian laws and regulations relating to the exploration and mining of mineral properties, as well as the possible effects of such activities on the environment. We conduct our operations substantially in accordance with such laws and regulations.

Discontinued operations. In 2014, we publicly announced our decision to discontinue operations and sell any remaining assets and equipment at four of our mining units: Poracota, Recuperada, Antapite and Shila-Paula. As a consequence, these mining units are presented in the Financial Statements as mining units held for sale. According to IFRS 5 “Non-current Assets Held for Sale and Discontinued Operations,” the related assets and liabilities are presented in the consolidated statement of financial position at the lower of cost and fair value less cost to sale. See Notes 1(e) and 2.4(x) to the Financial Statements.

Critical Accounting Policies and Estimates

The following is a discussion of our application of critical accounting policies that require our management, or Management, to make certain assumptions about matters that are highly uncertain at the time the accounting estimate is made, and where different estimates that Management reasonably could have used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, would have a material impact on our financial statements. Management has identified the following accounting estimates and policies as critical:

| · | mineral reserves and resources;

| · | unit-of-production depreciation;

| · | mine rehabilitation provision;

| · | inventories;

| · | impairment of non-financial assets;

| · | taxes; and

| · | fair value of contingent consideration.

Other significant accounting policies include:

| · | contingencies;

| · | development start date; and

| · | production start date.

We also have certain accounting policies that we consider to be important, such as our policies for investments carried at fair value, revenue recognition and exploration costs, that do not meet the definition of critical accounting estimates as they do not require Management to make estimates or judgments that are subjective or highly uncertain.

Management has discussed the development and selection of our critical accounting estimates with the Audit Committee of the Board of Directors.

Mineral reserves and resources

Recoverable proven and probable reserves are the part of a mineral deposit that can be economically and legally extracted or produced at the time of the reserve determination. The determination of reserves involves numerous uncertainties with respect to the ultimate geology of the ore bodies, including quantities, grades and recovery rates. Estimating the quantity and grade of reserves requires us to determine the size, shape and depth of our ore bodies by analyzing geological data, such as samplings of drill holes, tunnels and other underground workings. In addition to the geology of our mines, assumptions are required to determine the economic feasibility of mining these reserves, including estimates of future commodity prices and demand, the mining methods we use and the related costs incurred to develop and mine our reserves. The conceptual framework used to estimate proven and probable reserves for our wholly-owned mines as of December 31, 2013 were reviewed by an independent consultant Algon Investments S.R.L. and Geomineria S.A.C. as of December 31, 2014 and 2015. The conceptual framework used to estimate proven and probable reserves for El Brocal’s mines as of December 31, 2013 and 2014 were reviewed by independent consultant MINTEC Inc., which is in the process of reviewing the conceptual framework used to estimate proven and probable reserves for El Brocal’s mines as of December 31, 2015.

| 65 |

Changes in estimated reserves could affect mainly the depreciation of fixed assets related directly to mining activity, the provision for mine closure, the assessment of the deferred asset’s recoverability and the amortization period for development costs.

Unit-of-production depreciation

Reserves are used in determining the depreciation and amortization of mine-specific assets. This results in a depreciation or amortization charge proportional to the depletion of the anticipated remaining life of mine production. Each mine’s life is assessed annually to evaluate: (i) physical life limitations and (ii) present assessments of economically recoverable reserves of the mine property. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes are recorded prospectively.

This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life-of-mine production. The life of each item, which is assessed at least annually, is determined based on both its physical life limitations and present assessments of economically recoverable reserves of the mine property at which the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes in estimates are accounted for prospectively.

Mine rehabilitation provision

We record a provision for mine closure when a legally enforceable obligation arises, which is independent of the full depletion of the mine reserves. Once such an obligation has been appropriately measured, it is recorded by creating a liability equal to the amount of the obligation and recording a corresponding increase to the carrying amount of the related long-lived asset (mine development cost and property, plant and equipment). Over time, the amount of the obligation changes, impacting recording and accretion expenses. Additionally, the capitalized cost is depreciated and/or amortized based on the useful lives of the related assets.

Any difference in the settlement of the liability will be recorded in the results of the period in which such settlement occurs. The changes in the fair value of an obligation or the useful life of the related assets that occur from the revision of the initial estimates should be recorded as an increase or decrease in the book value of each of the obligation and related asset.

Following our accounting treatment, as of December 31, 2015, we have recorded an accrual for mine closure costs of US$166.4 million to comply with governmental requirements for environmental remediation for Buenaventura and its mining subsidiaries. Please see Note 16(b) to the Consolidated Financial Statements.

We assess our provision for closure of mining units annually. This assessment entails significant estimates and assumptions because there are a number of factors that will affect the ultimate liability for this obligation. These factors include estimating the scope and costs of closing activities, technological changes, regulatory changes, increases in costs compared to inflation rates and changes in the discount rates. Such estimates or assumptions may result in actual expenses in the future that differ from the amounts provisioned at the time the provisions were established. The provision at the date of this report presents our best estimate of the present value of future costs for the closure of mining units.

Inventories

Inventories are classified as short-term or long-term depending on the length of time that management estimates will be needed to reach the production state of concentrate extraction for each mining unit.

Net realizable value tests are performed at least annually and represent the estimated future sales price of the product based on prevailing spot metals prices at the reporting date, less estimated costs to complete production and bring the product to sale. Additionally, management also considers the time value of money in calculating the net realizable value of our long-term inventories.

| 66 |

Classified minerals, which are materials with metal content that were removed from the pit of the Colquijirca mining unit for treatment at the expansion operation plant, contain lower grade ore than the average of treated minerals and are available to continue in the process of recovery of mineral and concentrates. Because it is generally impracticable to determine the mineral contained in the classified mineral located in the deposit field near Tajo Norte by physical count, reasonable estimation methods are employed. The quantity of minerals delivered to classified mineral is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated copper, lead and zinc grades of material delivered to classified minerals.

For minerals outside leach platform inventories, finished and in-progress goods are measured by estimating the number of tons added and removed. The number of contained gold ounces is based on assay data, and the estimated recovery percentage is based on the expected processing method. Tonnages and ounces of mineral are verified by periodic surveys.

For minerals inside leach platform inventories, reasonable estimation methods are employed because it is generally impracticable to determine the mineral contained in leach platforms by physical count. The quantity of material delivered to leach platforms are based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated ore grades of material delivered to leach platforms.

Impairment of non-financial assets

We determine whether the operations of each mining unit are cash generating units, considering each mining unit operation independently. We assess at each reporting date whether there is an indication that an asset may be impaired. If any such indication exists, we estimate the asset’s recoverable amount. An asset’s recoverable amount is the higher of the asset’s fair value less costs to sell and its use value and is determined for an individual asset (cash-generating unit) unless the asset does not generate cash inflows that are clearly independent of those from other assets or groups of assets. These assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates, operating costs, and others.

A cash-generating unit is the smallest identifiable group of assets that generates cash inflows from continuing use that are independent of the cash inflow generated by other assets or groups of assets.

In assessing use value, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset.

During the fourth quarter of 2013, we updated our assessment of the recoverability of the book value of our long-term assets under the procedures established by IAS 36 – “Impairment of Assets” for all of our mining units and as a result we recorded an impairment loss for three of our mining units (Recuperada, Poracota and Antapite), which resulted in the recognition of asset impairment amounted to US$6.6 million (recognized as operating expense). These impairment charges had no impact on our operating cash flows. Cash flows used to assess recoverability of our long-lived assets and measure the carrying value of our mining operations were derived from current business plans using near-term price forecasts reflective of the current environment and Management’s projections for long-term average metal prices and operating costs.

During 2014, we updated our assessment of the recoverability of the book value of our long-term assets under the procedures established by IAS 36 – “Impairment of Assets” for all of our mining units and as a result we recorded an impairment loss for one of our mining units (Shila-Paula), which resulted in the recognition of asset impairment amounted to US$0.8 million (recognized as operating expense). This impairment charge had no impact on our operating cash flows. Cash flows used to assess recoverability of our long-lived assets and measure the carrying value of our mining operations were derived from current business plans using near-term price forecasts reflective of the current environment and Management’s projections for long-term average metal prices and operating costs. As noted above, as of December 31, 2015 and as of the date of this Form 20-F, four of our mining units (Recuperada, Poracota, Shila-Paula and Antapite) were and are held for sale.

During 2015, we updated our assessment of the recoverability of the book value of our long-term assets under the procedures established by IAS 36 – “Impairment of Assets” for all of our mining units and, as a result, we recorded an impairment loss for two of our mining units (La Zanja and Breapampa), which resulted in the recognition of asset impairment amount of US$11.2 million (recognized as an operating expense). These impairment charges had no impact on our operating cash flows. Cash flows used to assess recoverability of our long-lived assets and measure the carrying value of our mining operations were derived from current business plans using near-term price forecasts reflecting of the current environment and Management’s projections for long-term average metal prices and operating costs.

| 67 |

Our asset impairment evaluations required us to make several assumptions in the discounted cash flow valuation of (i) our individual mining operations, including near and long-term metal price assumptions, production volumes, estimates of commodity-based and other input costs and (ii) proven and probable reserve estimates, including any costs to develop the reserves and the timing of producing the reserves, as well as the appropriate discount rate. Our December 31, 2013, 2014 and 2015 impairment evaluation was based on price assumptions reflecting prevailing metals prices for the following years.

We believe events that could result in additional impairment of our long-lived assets include, but are not limited to, (i) decreases in future metal prices, (ii) decreases in estimated recoverable proven and probable reserves and (iii) any event that might otherwise have a material effect on mine site production levels or costs.

Deferred income tax asset and recoverability

In preparing our annual consolidated financial statements, we estimate the actual amount of taxes currently payable or receivable as well as deferred tax assets and liabilities attributable to temporary differences between the tax and book bases of assets and liabilities. Deferred income tax assets and liabilities are measured using tax rates applicable to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates and laws is recognized in income in the period in which such changes are enacted.

All deductible temporary differences and loss carry-forwards generate the recognition of deferred assets to the extent that it is probable that they can be used in calculating taxable income in future years. Deferred income tax liability is recognized for all deductible temporary differences and tax loss carry-forwards, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and unused tax losses can be utilized. The carrying amount of the deferred income tax asset is reviewed at each consolidated statement of financial position date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred asset to be utilized. Unrecognized deferred assets are reassessed at each consolidated statement of financial position date.

Deferred assets and liabilities are offset if there is a legal right to set them off and the taxes deferred relate to the same entity and the same tax authority.

Deferred tax assets, including those resulting from unused tax losses, require that we assess the likelihood that we would generate taxable earnings in future periods to apply the deferred tax assets. Estimated future taxable income is based on projections of cash flow from operations and application of the tax law existing in each jurisdiction. To the extent to which actual future cash flows and taxable income differ significantly from those estimated, our ability to realize the deferred tax assets posted as of the reporting date may be affected.

In addition, future changes in the tax law in jurisdictions where we operate could limit our ability to obtain tax deductions in future periods.

As of December 31, 2015, 2014 and 2013, our valuation allowance totaled US$18.2 million, US$4.2 million, and US$6.4 million.

Fair Value of contingent consideration

The contingent consideration arising from a business combination is measured at fair value at the date of acquisition, as part of the business combination. If the contingent consideration is eligible to be recognized as a financial liability the fair value is subsequently re-measured at each date of the consolidated financial statements. Determining the fair value of the contingent consideration is based on a model of discounted future cash flows. The key assumptions take into account the likelihood of achieving each goal of financial performance as well as the discount factor.

Segment Reporting

Management has determined its operating segments based on reports that the Company’s Chief Operating Decision Maker (the “CODM”) uses for making decisions. The Company’s operations are organized into business units based on its products and services, activities and geographic locations. The broad categories of the Company’s business units are:

| · | Production and sale of minerals;

| · | Exploration and development activities;

| · | Construction and engineering services;

| · | Energy generation and transmission services;

| · | Insurance brokerage;

| · | Rental of mining concessions;

| · | Holding of investment in shares (mainly in Yanacocha and Chaupiloma); and

| · | Industrial activities.

The CODM monitors the operating results of the business units separately for the purpose of making decisions about resource allocation and performance assessment. Segment performance is evaluated based on operating profit or loss and is measured consistently with operating profit or loss in the Company’s consolidated financial statements. Also, the Company’s financing and income taxes are managed at the corporate level and are not allocated to the operating segments, except for those entities which are managed independently. See Note 31 to the Financial Statements.

Contingencies

Contingent liabilities, when identified, are assessed as either remote, possible or probable. Contingent liabilities are recorded in the consolidated financial statements when it is probable that future events will confirm them and when their amount can be reasonably estimated. Contingent liabilities deemed as possible are only disclosed, together with a possible debit range, when determinable, in notes to the Financial Statements.

Contingent assets are not recognized in the financial statements; however, they may be disclosed in notes to the financial statements if it is probable that such contingent assets will be realized. See Note 29(f) and (g) to the Financial Statements.

Determining contingencies inherently involves the exercise of judgment and calculation of the estimated outcomes of future events.

Development start date

We assess the status of each exploration project of our mining units to determine when the development phase begins. One of the criteria used to evaluate the development start date is when we determine that the property can be economically developed.

Production start date

We assess the stage of each mine under development to determine when a mine moves into the production stage. The criteria used to assess the start date are determined based on the nature of each mining project, the complexity of a plant and its location. We consider various relevant criteria for assessing when the mine is substantially complete and ready for its planned use. Some of these criteria are the level of capital expenditure compared to development cost estimates, a reasonable testing period for the mine’s plant and equipment and the ability to produce ongoing production of metal.

| 69 |

When a mine development project moves into the production stage, the capitalization of certain costs ceases, and they are considered as inventory or expenses, except for costs that qualify for capitalization relating to mining asset additions or improvements, underground mine development or mineable reserve development. It is also at this point that depreciation or amortization commences.

Useful life of property, plant and equipment

Straight-line method

Depreciation is calculated under the straight-line method of accounting considering the lower of estimated useful lives of the asset or estimated reserves of the mining unit. The useful lives are the following:

Property, Plant and Equipment |  | Estimated Years of Useful Life
Buildings, constructions and other |  | Between 6 and 20
Machinery and equipment |  | Between 5 and 10
Transportation units |  | 5
Furniture and fixtures |  | 10
Computer equipment |  | 4

An item of property, plant and equipment is de-recognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising from de-recognizing an asset (calculated as the difference between the proceeds from the sale and the book value of the asset) is included in the consolidated statement of profit or loss in the year the asset is de-recognized.

Revenues

According to our accounting policies, revenue is recognized to the extent that it is probable that the economic benefits will flow to us. Revenue is measured at the fair value of the consideration received, excluding discounts and other sales taxes or duty.

Revenues from sales of concentrates, gold and silver are recognized when the significant risks and rewards of ownership have been transferred, which is considered to occur when title passes to the customer. This generally occurs when the product is physically transferred to the buyer.

Revenues for engineering services rendered by BISA are recognized based on the progress of the current service contracts.

Revenues for construction services rendered by BISA Construction S.A. are recognized when the outcome of a contract can be estimated reliably. Contract revenue associated with a construction contract is recognized by reference to the stage of completion of the contract activity at the end of the reporting period.

Fair value of embedded derivative for concentrate sales

Substantially all of our concentrate sales contracts provide final pricing in a specified period (generally one to four months from the shipment date) based on quoted LME prices. We ultimately receive market prices based on prices in the specified future period, however, the accounting rules applied to these sales result in changes recorded as revenue until the specified future period. We record revenues and invoice customers at the time of shipment based on current LME prices, which result in an embedded derivative on our provisional priced concentrate sales that are adjusted to fair value through earnings of each period until the date of final pricing. To the extent final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is recorded in each reporting period until the date of final pricing. See Notes 21(a) and 32(b) to the Financial Statements.

Results of Operations for the Years Ended December 31, 2015 and 2014

Net sales of goods. Net sales of goods decreased by 18.95%, from US$1,067.3 million in 2014 to US$865.0 million in 2015. The following tables reflect the average realized prices and volumes of gold, silver, lead, zinc and copper sold during the years ended December 31, 2014 and 2015, as well as the variation in such average realized prices and volumes recorded for the year ended December 31, 2015 as compared to the year ended December 31, 2014:

(a) Gold sales. Average realized sales prices for gold decreased from US$1,263.32 per ounce in 2014 to US$1,151.45 per ounce in 2015. Gold sales volume decreased from 439,093 ounces in 2014 to 380,899 ounces in 2015, mainly due to a decreased gold production at our Breapampa mining unit. The combined effect of these changes resulted in a US$112.5 million decrease in income from sales of gold in 2015 as compared to 2014.

(b) Silver sales. Average realized sales prices for silver decreased from US$18.65 per ounce in 2014 to US$15.06 per ounce in 2015. Silver sales volume increased from 19,088,923 ounces in 2014 to 21,023,873 ounces in 2015, mainly due to increased silver production at our Uchucchacua, Colquijirca and Julcani mining units. The combined effect of these changes resulted in a US$38.5 million decrease in income from sales of silver in 2015 as compared to 2014.

(c) Lead sales. Average realized sales prices for lead decreased from US$2,106.87 per ton in 2014 to US$1,711.87 per ton in 2015. Lead sales volume increased from 18,820 tons in 2014 to 32,389 tons in 2015, mainly due to increased lead production at our Colquijirca mining unit. The combined effect of these changes resulted in a US$16.3 million increase in income from sales of lead in 2015 as compared to 2014.

(d) Zinc sales. Average realized sales prices for zinc decreased from US$2,243.76 per ton in 2014 to US$1,838.86 per ton in 2015. Zinc sales volume increased from 21,231 tons in 2014 to 55,529 tons in 2015, mainly due to increased zinc production at our Colquijirca mining unit. The combined effect of these changes resulted in a US$55.2 million increase in income from sales of zinc in 2015 as compared to 2014.

(e) Copper sales. Average realized sales prices for copper decreased from US$6,737.78 per ton in 2014 to US$4,514.93 per ton in 2015. Copper sales volume decreased from 40,263 tons in 2014 to 29,094 tons in 2015, mainly due to decreased copper production at our Colquijirca mining unit. The combined effect of these changes resulted in a US$139.9 million decrease in income from sales of copper in 2015 as compared to 2014.

Net sales of goods figures are obtained by deducting the refinery charges and penalties incurred (a total of US$196.2 million of refinery charges and penalties were incurred in 2015, compared with US$184.5 million incurred in 2014) and revenues from mining units held for sale (a total of US$0.4 million revenues provided from mining units held for sales in 2015, compared with US$5.1 million provided in 2014) from the gross sales of all metals sold. See Note 21(a) to the Financial Statements.

Sales of services decreased by 23.9%, from US$71.6 million in 2014 to US$54.5 million in 2015, mainly due to a US$18.1 million decrease in sales of services in our construction and engineering segments, a result of a reduction in the number of contracts related to the development and construction of mining projects in 2015.

| 71 |

Royalty income. In 2015, royalty income received by our subsidiary Chaupiloma amounted to US$32.4 million, representing a 12.1% decrease from the US$36.9 million in royalty income received in 2014. This decrease was due to a decrease in 2015 in the net sales of Yanacocha, which was primarily due to a decrease in the average realized price of gold and a decrease in production at Yanacocha. We hold a 60% interest in Chaupiloma, to which Yanacocha pays a royalty that corresponds to three percent of its net sales.

Total operating costs. Total operating costs increased by 0.2%, from US$949.5 million in 2014 to US$951.8 million in 2015, due to changes in the following components:

(a) Cost of sales of goods, excluding depreciation and amortization, increased by 0.87%, from US$533.0 million in 2014 to US$537.7 million in 2015.

(b) Cost of services, excluding depreciation and amortization, decreased by 35.3% from US$81.5 million in 2014 to US$52.7 million in 2015, which was mainly due to costs from our construction and engineering unit decreasing by US$20.5 million as a result of lower net sales and a lower headcount.

(c) Exploration in operating units decreased by 6.5%, from US$97.9 million in 2014 to US$91.5 million in 2015. This decrease was primarily due to a decrease of US$10.1 million in diamond drilling activities at the Orcopampa mining unit, which was partially offset by an increase of US$1.7 million and US$1.3 million at the Julcani and Breapampa mining units, respectively, due to increased exploration efforts. See Note 23 to the Consolidated Financial Statements.

(d) Depreciation and amortization costs increased by 16.2%, from US$208.7 million in 2014 to US$242.5 million in 2015, mainly due to:

| · | higher depreciation and amortization costs incurred in the La Zanja mining unit of US$51.8 million, which increased from US$53.2 million in 2014 to US$105.0 million in 2015 as a result of the decrease in the reserves during 2015.

| · | higher depreciation and amortization costs incurred in the Colquijirca mining unit of US$18.7 million, which increased from US$27.0 million in 2014 to US$45.7 million in 2015 as a result of the capitalization of the expansion project at the beginning of 2015.

| · | lower depreciation costs incurred in the Breapampa mining unit of US$25.8 million, which decreased from US$35.7 million in 2014 to US$9.9 million in 2015 due to the lower operations during 2015.

| · | lower depreciation and amortization costs incurred in the Orcopampa and Mallay mining units of US$6.0 million and US$9.3 million, respectively, which decreased from US$48.0 million in 2014 to US$32.7 million in 2015 as a result of changes in the reserves during 2015.

(e) Mining Royalties decreased by 3.6%, from US$28.4 million in 2014 to US$27.4 million in 2015. Royalties paid to third parties by Orcopampa amounted to US$21.7 million and US$21.9 million in 2014 and 2015, respectively. Royalties paid to the Peruvian government amounted to US$6.7 million and US$5.5 million in 2014 and 2015, respectively. The increase in royalties paid to third parties are explained by the higher production in Orcopampa, partially offset by the decrease in the price of gold in 2015. The decrease in royalties paid to Peruvian government was primarily due to the decrease in the price of gold in 2015, compared with 2014.

Total operating expenses. Operating expenses decreased by 10.3%, from US$164.7 million in 2014 to US$147.7 million in 2015, due to changes in the following components:

(a) Administrative expenses decreased by 14.4%, from US$101.1 million in 2014 to US$86.5 million in 2015, mainly due to:

| · | a decrease of US$8.3 million in the construction and engineering unit due to a decrease in the contracts during 2015;

| 72 |

| · | a decrease of US$3.7 million in the La Zanja mining unit due to a provision for environmental contingencies for US$4.3 million recorded in 2014; and

| · | a decrease of US$5.2 million in the Breapampa mining unit due to the reduction of operations during 2015 in line with the depletion of its reserves.

(b) Exploration in non-operating areas decreased by 38.8 percent, from US$50.0 million in 2014 to US$30.6 million in 2015 due to decreased expenditures in exploration activities beginning in 2014, primarily in the Tambomayo and Alejandra projects. See Note 26 to the Financial Statements.

(c) Impairment loss of long-lived assets increased by US$11.2 million as a result of our assessment of the recoverability of the book value of our long-term assets under the procedures established by IAS 36 for two of our mining units (La Zanja and Breapampa).

Operating profit (loss). As a result of the foregoing, we generated an operating profit of US$61.6 million in 2014 compared to an operating loss of US$147.6 million in 2015.

Other income (expense), net. Other income (expenses), net increased by 680.0% from US$26.1 million in 2014 to US$203.7 million in 2015, mainly explained by:

(a) Share in the results of associates under equity method. Loss from equity investments in associates increased by 132.4%, from US$74.6 million in 2014 to US$173.4 million in 2015, primarily due to an increase in net loss from our equity investment in our associate company, Yanacocha, and a decrease in net income from our equity investment in Cerro Verde.

Net loss from our interest in Yanacocha increased by 12.5%, from US$174.7 million in 2014 to US$196.5 million in 2015. Net income from our interest in Cerro Verde decreased by 91.6 percent, from US$77.9 million in 2014 to US$6.5 million in 2015. Finally, net income from our interest in Coimolache decreased by 25.3%, from US$22.3 million in 2014 to US$16.6 million in 2015.

(b) Gain on business combination. In 2014, we recognized a gain of US$59.9 million in connection with our acquisition of the controlling interest in Canteras del Hallazgo S.A.C. (“CDH”) from Minera Gold Fields Perú S.A. (“MGFPSA”) due to the revaluation of the previously held equity interest at fair value as of the acquisition date.

(c) Finance costs. Finance costs increased by 144.1%, from US$11.3 million in 2014 to US$27.6 million in 2015, primarily due to:

| · | lower capitalization of borrowings costs of US$18.8 million due to the lack of significant qualifying assets in 2015;

| · | a decrease of the interests of financial obligations of US$8.9 million, partially offset by the increase of the interests of bank loans of US$4.8 million; and

| · | an increase of US$1.6 million in the financial cost related to closing mining units, due to the higher provision recorded in 2015.

Income tax. Provision for income tax decreased by 77.6%, from US$66.0 million in 2014 to US$14.8 million in 2015, primarily due to a decrease in the provision for income tax at the El Brocal and La Zanja mining units, and at the corporate unit of US$25.7 million, US$18.1 million and US$11.3 million, respectively, due to those segments showing net losses during 2015.

Non-controlling interest income (loss). Non-controlling interest changed from an income of US$14.4 million in 2014 to a loss of US$58.3 million in 2015, primarily due to a decrease in contribution of profits from the La Zanja and El Brocal units by US$33.2 million and US$38.4 million, respectively. See Note 19(a) to the Financial Statements.

| 73 |

Net loss. As a result of the foregoing, net loss increased from US$61.6 million in 2014 to US$375.5 million in 2015. Net loss was 5.2% of operating income in 2014 and 39.5% of operating income in 2015.

Julcani. Net sales of goods increased by US$0.5 million in 2015 as compared to 2014 due to increases in the volume of silver and lead sold at that unit, partially offset by a decline in the average realized price of silver.

Mallay. Net sales of goods decreased by US$11.0 million in 2015 as compared to 2014 due to a decline in the average realized price of silver, partially offset by an increase in the amount of silver sold at that unit.

Breapampa. Net sales of goods decreased by US$86.1 million in 2015 as compared to 2014 due to a decrease in the volume of silver and gold sold and a decline in the average realized price of those minerals.

Orcopampa. Net sales of goods decreased by US$9.9 million in 2015 as compared to 2014 due to a decline in the average realized prices of gold and silver, partially offset by a 5% increase in gold sold (from 204,862 ounces sold in 2014 to 214,821 ounces sold in 2015) and a 38% increase in silver sold (from 401,782 ounces sold in 2014 to 555,314 ounces sold in 2015) at that unit.

| 74 |

Uchucchacua. Net sales of goods decreased by US$36.5 million in 2015 as compared to 2014 due to a decline in the average realized prices of lead and silver, partially offset by an increase in the amount of lead and silver sold at that unit.

La Zanja. Net sales of goods decreased by US$24.3 million in 2015 as compared to 2014 due to a decline in gold and silver prices, and a decrease in the volume of silver sold from 418,565 ounces sold in 2014 to 324,151 ounces sold in 2015 and gold sold from 143,151 ounces sold in 2014 to 142,300 ounces sold in 2015.

Colquijirca. Net sales of goods decreased by US$38.7 million in 2015 as compared to 2014 due to a decline in mineral prices, partially offset by an increase in tons of lead and zinc and ounces of silver sold during 2015.

Sales of services - construction and engineering segment. Net sales for the construction and engineering segment decreased by US$18.1 million in 2015 as compared to 2014 due to a reduction in the development and construction of mining projects.

Sales of services - insurance brokerage segment. Net sales for the insurance brokerage segment increased by US$1.3 million in 2015 as compared to 2014 due to an increase in the number of clients in the insurance portfolio due to our strategic associations with smaller brokers.

(a) Gold sales. Average realized sales prices for gold decreased from US$1,392.18 per ounce in 2013 to US$1,263.32 per ounce in 2014. Gold sales volume decreased from 458,499 ounces in 2013 to 439,093 ounces in 2014, mainly due to a decreased gold production at our Orcopampa and Breapampa mining units. The combined effect of these changes resulted in a US$85.9 million decrease in income from sales of gold in 2014 as compared to 2013.

(b) Silver sales. Average realized sales prices for silver decreased from US$22.33 per ounce in 2013 to US$18.65 per ounce in 2014. Silver sales volume increased from 16,329,314 ounces in 2013 to 19,088,923 ounces in 2014, mainly due to increased silver production at our Uchucchacua, Colquijirca and Julcani mining units. The combined effect of these changes resulted in a US$7.6 million decrease in income from sales of silver in 2014 as compared to 2013.

(c) Lead sales. Average realized sales prices for lead increased from US$2,104.63 per ton in 2013 to US$2,106.87 per ton in 2014. Lead sales volume decreased from 26,584 tons in 2013 to 18,820 tons in 2014, mainly due to decreased lead production at our Colquijirca and Uchucchacua mining units.

Sales of goods figures are obtained by deducting the refinery charges and penalties incurred (a total of US$184.5 million of refinery charges and penalties were incurred in 2014, compared with US$178.9 million incurred in 2013) and revenues from mining units held for sale (a total of US$5.1 million revenues provided from mining units held for sales in 2014, compared with US$25.8 million provided in 2013) from the gross sales of all metals sold. See Note 21(a) to the Financial Statements.

Net sales of services. Sales of Services decreased by 10%, from US$79.6 million in 2013 to US$71.6 million in 2014, mainly explained by the decrease of US$29.6 million in 2014 as compared to 2015 due to a reduction in the development and construction of mining projects and an increase of US$5.1 million in 2014 as compared to 2013 due to an increase in the energy generation and transmission.

Royalty income. In 2014, royalty income received by our subsidiary Chaupiloma amounted to US$36.9 million, representing a 17% decrease from the US$44.2 million in royalty income received in 2013. This decrease was due to a decrease in 2014 in the net sales of Yanacocha, which was primarily due to a decrease in the average realized price of gold and a decrease in production at Yanacocha. We hold a 60% interest in Chaupiloma, to which Yanacocha pays a royalty that corresponds to 3% of its net sales.

Total operating costs. Total operating costs increased by 3%, from US$918.7 million in 2013 to US$949.5 million in 2014, due to changes in the following components:

(a) Cost of sales of goods, excluding depreciation and amortization, increased by 3.9%, from US$513.2 million in 2013 to US$533.0 million in 2014, due to:

| · | a US$35.6 million increase in the services rendered by third parties at the Ucchuchacua mining unit, which was partially offset by (i) a decrease of US$14.7 million in our Orcopampa mining unit due to fewer services provided by third parties and a decrease in the consumption of materials and supplies.

(b) Cost of sales of services, excluding depreciation and amortization, decreased by 28.6%, from US$114.1 million in 2013 to US$81.5 million in 2014, mainly due to:

| · | a decrease of US$22.8 million in our construction and engineering unit as a result of lower net sales and a lower headcount; and

| · | a decrease of US$6.2 million in the energy generation and transmission segment due to the decline in energy purchases resulting from the Huanza hydroelectric plant beginning operations in 2014.

(c) The cost of exploration of units in operation decreased by 4%, from US$101.9 million in 2013 to US$97.9 million in 2014. This decrease was primarily due to a decrease of US$6.1 million and US$2.5 million in diamond drilling activities at the Orcopampa and Breapampa mining units, respectively, which was partially offset by an increase of US$3.9 million at the Julcani mining unit due to increased exploration efforts at Acchilla. See Note 23 to the Financial Statements.

(d) Depreciation and amortization costs increased by 31%, from US$159.1 million in 2013 to US$208.7 million in 2014, due to:

| · | higher depreciation and amortization costs incurred in the La Zanja mining unit, which increased from US$27.9 million in 2013 to US$53.2 million in 2014 as a result of increased mine development costs and amortization and fixed assets purchases;

| · | higher depreciation and amortization costs incurred in the Julcani and Mallay mining units, which increased from US$24.9 million in 2013 to US$36.5 million in 2014 as a result of work-in-progress put into operation;

| · | higher depreciation costs incurred in the Breapampa mining unit, which increased from US$25.5 million in 2013 to US$35.7 million in 2014 due to the start of operations in new pad stages; and

| 77 |

| · | depreciation costs incurred by our corporate unit, which increased by US$7.2 million in 2014 due to the start of operations at the Rio Seco subsidiary, which was partially offset by a decrease in depreciation costs incurred in the Colqujirca mine from US$35.6 million in 2013 to US$26.9 million in 2014 due to the full depreciation of the R-7 tailing dam in 2013.

(e) Mining royalties decreased by 6.6%, from US$30.4 million in 2013 to US$28.4 million in 2014. Royalties paid to third parties by Orcopampa amounted to US$23.8 million and US$21.7 million in 2013 and 2014, respectively. Royalties paid to the Peruvian government amounted to US$6 million and US$6.8 million in 2013 and 2014, respectively. The decrease in royalties paid to third parties and the Peruvian government was primarily due to a 10% decrease in gold production at the Orcopampa mining unit from 224,671 ounces produced in 2013 to 203,226 ounces produced in 2014, and the decrease in the price of gold in 2014, compared with 2013.

Total operating expenses. Operating expenses increased by 31.1%, from US$125.6 million in 2013 to US$164.7 million in 2014, due to changes in the following components:

(a) Administrative expenses increased by 35%, from US$75.1 million in 2013 to US$101.1 million in 2014, due to an increase of administrative expenses at the corporate unit of US$21.2 million from the reversal of expenses by US$20.2 million recorded in 2013 for long-term officers’ compensation (stock appreciation rights), and an increase of US$7.9 million in the construction and engineering unit due to increased labor costs, which was partially offset by a decrease of US$4.3 million in the Orcopampa mining unit due to a decrease in labor expenses. See Note 25 to the Financial Statements.

(b) Exploration in non-operating areas increased by 52%, from US$32.8 million in 2013 to US$50.0 million in 2014, due to increased expenditures in exploration activities beginning in 2014, primarily in the Alejandra and Tambomayo projects. See Note 26 to the Financial Statements.

Operating profit. As a result of the foregoing, operating income decreased by 71% from US$215.2 million in 2013 to US$61.6 million in 2014.

Other income (expense), net. Other income (expenses), net decreased by 79.0% from US$124.6 million in 2013 to US$26.1 million in 2014, mainly explained by:

(a) Share in the results of associates under equity method. Loss from equity investments in associates decreased by 35%, from US$114.1 million in 2013 to US$74.6 million in 2014, primarily due to a decrease in net loss from our equity investment in our associate company, Yanacocha, which was partially offset by a decrease in net income from our equity investment in Cerro Verde. Net loss from our interest in Yanacocha decreased by 30%, from US$251.1 million in 2013 to US$174.7 million in 2014. Net income from our interest in Cerro Verde decreased by 33%, from US$116.2 million in 2013 to US$77.9 million in 2014. Finally, net income from our interest in Coimolache increased by 7%, from US$20.8 million in 2013 to US$22.3 million in 2014.

(b) Gain on business combination. In 2014, we recognized a gain of US$59.9 million in connection with our acquisition of the controlling interest in CDH from MGFPSA due to the revaluation of the previously held equity interest at fair value as of the acquisition date.

(c) Finance costs. Finance costs increased by 14%, from US$9.9 million in 2013 to US$11.3 million in 2014, primarily due to an increase in the cost of the financial leasing facility related to the construction of the Huanza hydroelectric plant.

Income tax. Provision for income tax decreased by 24%, from US$86.5 million in 2013 to US$66.0 million in 2014, primarily due to a decrease in the provision for income tax at the corporate unit of US$18.1 million caused by a decrease in taxable income of that unit, a decrease in the provision for income tax at the La Zanja mining unit of US$16.8 million and a decrease in other units of US$1.1 million, which was partially offset by an increase of US$16.6 million at the Colquijirca mining unit due to higher sales.

Non-controlling interest. Non-controlling interest income decreased by 48%, from US$27.5 million in 2013 to US$14.4 million in 2014, primarily due to a decrease in contribution of profits from the La Zanja and Chaupiloma units by US$18.0 million and US$2.1 million, respectively. See Note 19(a) to the Financial Statements.

| 78 |

Net profit (loss). As a result of the foregoing, net loss decreased by 23%, from US$79.7 million in 2013 to US$61.6 million in 2014. Net loss was 7% of operating income in 2013 and 5% of operating income in 2014.

| · | an increase in payments to suppliers and third parties, from US$752.8 million in 2013 to US$805.4 million in 2014.

These changes were partially offset by:

| · | a decrease in income tax paid, from US$66.4 million in 2013 to US$33.2 million in 2014;

| · | a decrease in payments to workers, from US$216.8 million in 2013 to US$203.5 million in 2014;

| · | a decrease in royalty payments made, from US$30.6 million in 2013 to US$22.6 million in 2014, primarily due to fewer royalty payments made to third parties;

| · | an increase in dividends received from Coimolache, from US$9.8 million in 2013 to US$12.9 million in 2014; and

| · | a decrease in interest payments made, from US$11.5 million in 2013 to US$9.4 million in 2014.

Cash used in investing activities for the years ended December 31, 2015 and 2014. Net cash and cash equivalents used in investing activities were US$341.7 million in 2015, compared with US$292.7 million in 2014. The increase in net cash flow used in investing activities was primarily due to:

| 81 |

| · | an increase in loans granted to associates (Cerro Verde), from US$0 in 2014 to US$124.8 million in 2015;

| · | a decrease in proceeds from loans to associates, from US$15.5 million in 2014 to US$0 in 2015; and

| · | an increase in payments related to acquisitions of other assets, from US$0 in 2014 to US$10.2 million in 2015.

These changes were partially offset by:

| · | a decrease in cash contributions granted to associates, from US$7.0 million in 2013 to US$2.0 million in 2014.

These changes were partially offset by:

Short-Term Debt

We borrow from time to time short-term unsecured loans from local Peruvian banks to supplement our working capital needs at favorable short-term interest rates. As of December 31, 2015 and 2014, the amount outstanding under such short-term loans was US$344.5 million and US$40.0 million, respectively. In 2015, we used the proceeds of such short-term loans to fund the construction of the Tambomayo project, to loan funds to Cerro Verde, to increase capital in El Brocal and for other general working capital purposes.

Long-Term Debt

On December 2, 2009 Banco de Credito del Peru executed a financial lease agreement with Conenhua, Huanza and us in the amount of US$119.0 million for construction of a hydroelectric power station. The lease was executed in favor of Huanza as lessee. The term of the lease is six years from August 2014 and the interest rate is three-month LIBOR plus 4.00%. As of December 31, 2015 and 2014, the amount outstanding under this lease was US$104.1 million and US$114.2 million, respectively.

On June 30, 2014, Banco de Credito del Perú extended this financial lease agreement with Conenhua, Huanza and us in the amount of US$108.8 million. The term of the lease is six years from August 2014 and the interest rate is three-month LIBOR plus 4.20%. As of December 31, 2015 and 2014, the amount outstanding under this lease was US$84.0 million and US$85.0 million, respectively.

On September 25, 2013, El Brocal began the process of entering into a financing arrangement with Banco de Crédito del Perú in an aggregate amount of US$180.0 million in the form of a series of sale and leaseback agreements relating to certain specified El Brocal assets, including equipment, machinery and production plants located in the Colquijirca mining unit. The first disbursement of US$116.5 million was received in November 2013, which was used to repay El Brocal’s medium term loan with Banco de Crédito del Perú during the fourth quarter of 2013. The second disbursement of US$63.5 million was received in January 2014. The renewable arrangement had a term of five years that commenced on the first lease payment date in March 2014. During the term of the arrangement, El Brocal has the right to repurchase the assets. On June 9, 2015, the Board of Directors of El Brocal approved the modification of the sale and finance leaseback contract in an aggregate amount of US$166.5 million. The new arrangement has a term of five years that commenced on the payment date in June 2015. The quarterly lease payments have an embedded interest rate of three-month LIBOR plus 4.7%. The agreements contain certain covenants, including several financial covenants such as a limitation on the payment of dividends by El Brocal. El Brocal’s obligations under the agreements are supported by trust contracts, which, among other things, relate to collection rights, sales contracts and cash flows granting Banco de Crédito del Perú the right to receive all cash flows before any funds are made available to El Brocal. The obligations of El Brocal under these agreements are not recourse to, or guaranteed by, Buenaventura or any of its other subsidiaries. The compliance with the financial ratios described above is monitored by El Brocal’s management. In 2015, Management obtained a waiver for any possible breach of the financial ratios that occur until December 31, 2016.

On March 28, 2014, Banco de Crédito del Perú executed a financial lease agreement with BISA in the amount of US$14.9 million for the construction of a building with administrative offices. The term of the lease is five years and four months starting April 2014 and the interest rate is three-month LIBOR plus 4.60%.

Exploration Costs and Capital Expenditures

We have budgeted approximately US$250 to US$300 million for capital expenditures for 2016. These budgeted capital expenditures include finishing the construction of the Tambomayo project and continuing with the development of the San Gabriel project.

During 2015, we spent US$30.6 million on “exploration in non-operating areas” and US$91.5 million on “exploration in units in operations.” Our “exploration in non-operating areas” investments mainly focused on the following exploration projects: Tambomayo, Alejandra, Marcapunta, and Pisacalla projects. Our “exploration in units in operations” investments were mainly focused in the Orcopampa, Uchucchacua and Julcani mining units.

In 2016, we intend to invest approximately US$70 million to US$80 million in exploration of units in operation and US$10 million to US$20 million mainly in exploration of non-operating areas, including Tambomayo, Yumpag, Palla Palla and Daniela, among others.

We expect that we will meet our working capital, capital expenditure and exploration expense requirements for the next several years from internally generated funds, cash on hand and dividends received from our investments in non-consolidated mining operations, including Yanacocha. Additional financing, if necessary for the construction of any project, is expected to be obtained from borrowings under bank loans and the issuance of debt securities. There can be no assurance, however, that sufficient funding will be available to us from the internal or external sources to finance any future capital expenditure program, or that external funding will be available to us for such purpose on terms or at prices favorable to us. A very significant decline in the prices of gold and silver would be reasonably likely to affect the availability of such sources of liquidity. In addition, if we fund future capital expenditures from internal cash flow, there may be fewer funds available for the payment of dividends.

Recent Accounting Pronouncements

IFRS

We prepare and present the Financial Statements in accordance with IFRS as issued by the IASB. For periods up to and including the year ended December 31, 2010, we prepared our financial statements in accordance with Peruvian GAAP. Our consolidated financial statements for the year ended December 31, 2011 were the first that we prepared in accordance with IFRS. We applied IFRS 1 “First-Time Adoption of International Financial Reporting Standards” to the opening balance as of January 1, 2010, the date of our transition to IFRS. The IFRS 1 application implies that all the standards are applied retrospectively at the transition date, including certain mandatory exceptions and voluntary exemptions defined in the standard. In addition, as a foreign private issuer in the United States, we are subject to less intensive reporting requirements and information regarding us may not be as readily disseminated into the market.

The standards and interpretations that are issued, but not yet effective, up to the date of issuance of our Financial Statements are disclosed below. We intend to adopt these standards, if applicable, when they become effective:

IFRS 9, “Financial Instruments: Classification and Measurement” In July 2014, the IASB issued the final version of IFRS 9 Financial Instruments which reflects all phases of the financial instruments project and replaces IAS 39 and all previous versions of IFRS 9. IFRS 9 brings together all three aspects of the accounting for financial instruments project: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for annual periods beginning on or after January 1, 2018, with early application permitted. Except for hedge accounting, retrospective application is required, but the provision of comparative information is not compulsory. For hedge accounting, the requirements are generally applied prospectively, with some limited exceptions. The adoption of IFRS 9 would have not significant effect on the classification and measurement of our financial assets and liabilities. IFRS 15, “Revenues from Contracts with Customers”

IFRS 15 was issued in May 2014 and establishes a new five-step model that will apply to revenue arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. The principles in IFRS 15 provide a more structured approach to measuring and recognizing revenue. The new revenue standard is applicable to all entities and will supersede all current revenue recognition requirements under IFRS. Either a full retrospective application or a modified retrospective application is required for annual periods beginning on or after January 1, 2018. Early adoption is permitted. We are currently assessing the impact of IFRS 15 and plans to adopt the new standard on the required effective date.

Amendments to IFRS 10 and IAS 28, Sale or contributions of assets between an investor and its associate or joint venture.

The amendments address the conflict between IFRS 10 Consolidated Financial Statements and IAS 28 in dealing with the loss of control of a subsidiary that is sold or contributed to an associate or joint venture. The amendments clarify that the gain or loss resulting from the sale or contribution of assets that constitute a business, as defined in IFRS 3, between an investor and its associate or joint venture, is recognized in full. Any gain or loss resulting from the sale or contribution of assets that do not constitute a business, however, is recognized only to the extent of unrelated investors’ interests in the associate or joint venture. These amendments must be applied prospectively and are effective for annual periods beginning on or after January 1, 2016, with early adoption permitted. These amendments will impact us to the extent that it undertakes future transactions of this nature, as this accounting approach differs from that which it would currently apply.

| B. | Research and Development

Not applicable.

| C. | Trend Information

Other than as disclosed in this Annual Report, we are not aware of any trends, uncertainties, demands, commitments or events which are reasonably likely to have a material effect upon our net sales or revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information to be not necessarily indicative of future operating results or financial condition.

For our exploration activities, there is no production, sales or inventory in a conventional sense. Our financial success is dependent upon the extent to which we are capable of discovering mineralization and the economic viability of exploration properties. The construction and operation of such properties may take years to complete and the resulting income, if any, cannot be determined with certainty. Further, the sales value of mineralization discovered by us is largely dependent upon factors beyond our control, including the market value at any given time of the metals produced.

| D. | Off-Balance Sheet Arrangements

There are no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

| E. | Tabular Disclosure of Contractual Obligations

As of December 31, 2015, we had no other commercial commitments.

| F. | Reconciliation of Costs Applicable to Sales and Cost Applicable to Sales per Unit Sold

Cost applicable to sales and Cost applicable to sales per unit of mineral sold are not measures of financial performance under IFRS, and may not be comparable to similarly titled measures of other companies. We consider Cost applicable to sales and Cost applicable to sales per unit of mineral sold to be key measures in managing and evaluating our operating performance. These measures are widely reported in the precious metals industry as a benchmark for performance, but do not have standardized meanings. You should not consider Cost applicable to sales or Cost applicable to sales per unit of mineral sold as alternatives to cost of sales determined in accordance with IFRS, as indicators of our operating performance. Cost applicable to sales and Cost applicable to sales per unit of mineral sold are calculated without adjusting for by-product revenue amounts.

In calculating these figures, we utilize financial records maintained with respect to the various mining units and subsidiaries, each on a standalone basis. Within the stand-alone accounts for each mining unit or subsidiary, we then allocate cost of sales (excluding depreciation and amortization), exploration in units in operation and selling expenses in the proportion to each mineral’s commercial value (realized price multiplied by volume sold).

The tables below set forth (i) a reconciliation of consolidated Cost of sales, excluding depreciation and amortization to consolidated Cost applicable to sales, (ii) reconciliations of the components of Cost applicable to sales (by mine and mineral) to the corresponding consolidated line items set forth on our consolidated statements of profit or loss for the years ended December 31, 2014 and 2015, and (iii) reconciliations of Cost of sales, excluding depreciation and amortization to Cost applicable to sales for each of our mining units. The amounts set forth in Cost applicable to sales and Cost applicable to sales per unit sold for each mine and mineral indicated in the tables below can be reconciled to the amounts set forth on our consolidated statements of profit or loss for the years ended December 31, 2014 and 2015 by reference to the reconciliations of Cost of sales, excluding depreciation and amortization (by mine and mineral), Selling Expenses (by mine and metal) expenses and Exploration in units in operations (by mine and mineral) to consolidated Cost of sales, excluding depreciation and amortization, consolidated Selling Expenses and consolidated Exploration in units in operations expenses, set forth below.

YANACOCHA

Introduction

The following discussion should be read in conjunction with the Yanacocha Financial Statements as of December 31, 2014 and 2015 and for the years ended December 31, 2013, 2014 and 2015 and the related Notes thereto included elsewhere in this Annual Report. The Yanacocha Financial Statements are prepared and presented in accordance with IFRS and in U.S. Dollars.

| A. | Operating Results

Overview

Yanacocha, the largest gold producer in South America, was established in Peru in January 1992, and commenced production activities in August 1993. Yanacocha’s operations are located in the Andes mountains in Northern Peru, in the area of Cajamarca which is located approximately 600 kilometers north of Lima and north of the city of Cajamarca, at an altitude of 4,000 meters above sea level. Yanacocha is 51.35% owned by Newmont Mining, through its wholly-owned subsidiary Newmont Second, 43.65% by us through our wholly-owned subsidiary Condesa, and 5% by IFC. Yanacocha is managed by Newmont Peru S.R.L. See “Item 4. Information on the Company—Yanacocha—B. Business Overview—Management of Yanacocha—General Manager/Management Agreement.”

The table below highlights Yanacocha’s key financial and operating results:

Summary of Financial and Operating Performance

|  | Year Ended December 31, |
|  | 2015 |  |  | 2014 |  |  | 2013 |
Gold sales (in thousands of US$) |  |  | 1,070,035 |  |  |  | 1,210,457 |  |  |  | 1,458,145 |
Gold sold (oz.) (*) |  |  | 924,175 |  |  |  | 967,970 |  |  |  | 1,023,173 |
Average gold price received (US$/oz.) |  |  | 1,159 |  |  |  | 1,250 |  |  |  | 1,425 |
Costs applicable to sales (US$/oz.) |  |  | 819 |  |  |  | 949 |  |  |  | 983 |
Other expenses, net (in thousands of US$) |  |  | 82,846 |  |  |  | 77,781 |  |  |  | 77,534 |
Net income (loss) (in thousands of US$) |  |  | (450,195 | ) |  |  | (400,338 | ) |  |  | (575,279 | )

(*) Ounces sold included El Tapado Oeste Pit, Cerro Negro Pit, Marleny Pit production and Verde Bioleach Demonstration Facility.

Gold sales. Gold sales decreased by 12%, or US$140 million, from 2014 to 2015, due to a decrease in the number of ounces sold and a decreased average realized price of gold. Lower ounces sold were proportionate to lower gold production. Gold ounces produced decreased 4.5% due to lower leach grade material placed on the leach pads containing fewer ounces. Yanacocha has not engaged in gold price hedging activities, such as forward sales or option contracts, to minimize its exposure to fluctuations in the price of gold.

Costs applicable to sales. Costs applicable to sales include: (i) operating costs, consisting primarily of direct production costs such as mining and treatment of the ore, which are the most significant components of costs applicable to sales, (ii) workers’ participation profit sharing of 8% of pre-tax profits based on Peruvian labor legislation, (iii) write downs of ore on leach pads to net realizable value expense and (iv) other costs. Costs applicable to sales decreased 19% or US$170 million from 2014 to 2015. Ounces sold decreased by 4.5% from 2014 to 2015. Costs applicable to sales per ounce of gold decreased by 14%, from US$949 in 2014 to US$819 in 2015.

Other expense (net). Other expense (net) increased 20% or US$15.7 million from 2014 to 2015, primarily due to higher losses associated with asset sales incurred in 2015 compared to 2014.

Income tax benefit (expense). Yanacocha’s financial and operating results included income and mining tax benefit of US$602.7 million in 2015 compared to an expense of US$30.5 million in 2014. The difference was primarily due to Yanacocha’s decreased profitability as the result of lower expenses compared to the prior year.

Dividends. During the years ended December 31, 2014 and 2015, Yanacocha did not pay dividends to its partners and did not reserve any money related to reinvestment programs.

Critical Accounting Policies

Yanacocha has furnished us with a discussion of its critical accounting policies or methods used in the preparation of its financial statements. Critical accounting policies are those that are reflective of significant judgments and uncertainties and could potentially impact results under different assumptions and conditions. See Note 2 to the Yanacocha Financial Statements for a more complete listing Yanacocha’s accounting policies.

Currency

The Yanacocha Financial Statements are stated in U.S. Dollars, Yanacocha’s functional currency, as most of its transactions are traded, collected and paid in such currency. Transactions in other currencies are recorded in U.S. Dollars based on exchange rates prevailing at the time of such transactions. Monetary assets and liabilities denominated in other currencies are translated into the U.S. Dollar at exchange rates prevailing at the balance sheet dates, and any resulting gains or losses are reflected in current earnings.

Stockpiles, Ore on Leach Pads and Inventories

Costs that are incurred in or benefit the productive process are accumulated as stockpiles, ore on leach pads and inventories. Stockpiles, ore on leach pads and inventories are carried at the lower of average cost or net realizable value. Net realizable value represents the estimated future sales price of the product based on current and long-term metals prices, less the estimated costs to complete production and bring the product to sale. Write-downs of stockpiles, ore on leach pads and inventories to net realizable value are reported as a component of Costs applicable to sales. The current portion of stockpiles, ore on leach pads and inventories is determined based on the expected amounts to be processed within the next twelve months. Stockpiles, ore on leach pads and inventories not expected to be processed within the next twelve months are classified as long-term. The major classifications are as follows:

Stockpile. Stockpiles represent ore that has been extracted from the mine and is available for further processing. Stockpiles are measured by estimating the number of tons added and removed from the stockpile, the number of contained ounces (based on assay data) and the estimated metallurgical recovery rates (based on the expected processing method). Stockpile ore tonnages are verified by periodic surveys. Costs are allocated to stockpiles based on relative values of material stockpiled and processed using current mining costs incurred up to the point of stockpiling the ore, including applicable overhead and amortization relating to mining operations, and removed at each stockpile’s average cost per recoverable unit.

Ore on Leach Pad. The recovery of gold from certain gold oxide ores is achieved through the heap leaching process. Under this method, ore is placed on leach pads where it is treated with a chemical solution, which dissolves the gold contained in the ore. The resulting gold-bearing solution is further processed in a plant where the gold is recovered. Costs are added to ore on leach pads based on current mining costs, including applicable overhead and amortization relating to mining operations. Costs are removed from ore on leach pads as ounces are recovered based on the average cost per recoverable ounce of gold on the leach pad.

The estimates of recoverable gold on the leach pads are calculated from the quantities of ore placed on the pads (measured tons added to the leach pads), the grade of ore placed on the leach pads (based on assay data) and a recovery percentage (based on ore type). In general, the leach pads recover approximately 50% to 95% of the ultimate recoverable ounces in the first year of leaching, declining each year thereafter until the leaching process is complete.

Although the quantities of recoverable gold placed on the leach pads are reconciled by comparing the grades of ore placed on the pads to the quantities of gold actually recovered (metallurgical balancing), the nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, the metallurgical balancing process is constantly monitored and estimates are refined based on actual results over time. Historically, Yanacocha’s operating results have not been materially impacted by variations between the estimated and actual recoverable quantities of gold on its leach pads. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted for on a prospective basis.

| 93 |

In-process Inventory. In-process inventories represent materials that are currently in the process of being converted to a saleable product. Yanacocha’s conversion processes vary depending on the nature of the ore and the specific processing facility, and include mill in-circuit and leach in-circuit. In-process material is measured based on assays of the material fed into the process and the projected recoveries of the respective plants. In-process inventories are valued at the average cost of the material fed into the process attributable to the source material coming from the mines, stockpiles and/or leach pads plus the in-process conversion costs, including applicable amortization relating to the process facilities incurred to that point in the process.

Precious Metals Inventory. Precious metals include gold doré and/or gold bullion. Precious metals that result from Yanacocha’s mining, processing and refining activities are valued at the average cost of the respective in-process inventories incurred before the refining process, plus applicable refining costs.

Mine Development. Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, and the removal of overburden to initially expose an ore body at open pit surface mines. Costs incurred before mineralization is classified as proven and probable reserves are expensed and classified as Exploration or Advanced projects expense. Capitalization of mine development project costs, that meet the definition of an asset, begins once mineralization is classified as proven and probable reserves.

Drilling and related costs are capitalized for an ore body where proven and probable reserves exist; the activities are directed at obtaining additional information on the ore body or converting mineralized material to proven and probable reserves. All other drilling and related costs are expensed as incurred. Drilling costs incurred during the production phase for operational ore control are allocated to inventory costs and then included as a component of Costs applicable to sales.

The cost of removing overburden and waste materials to access the ore body at an open pit mine before the production phase are referred to as “pre-stripping costs.” Pre-stripping costs are capitalized during the development of an open pit mine. Where multiple open pits exist at a mining complex utilizing common processing facilities, pre-stripping costs are capitalized at each pit. The removal and production of de minimis saleable materials may occur during development and are recorded as Other income, net of incremental mining and processing costs.

The production phase of an open pit mine commences when saleable minerals, beyond a de minimis amount, are produced. Stripping costs incurred during the production phase of a mine are variable production costs that are included as a component of inventory to be recognized in Costs applicable to sales in the same period as the revenue from the sale of inventory. Yanacocha’s definition of a mine and the mine’s production phase may differ from that of other companies in the mining industry resulting in incomparable allocations of stripping costs to deferred mine development and production costs. Other mining companies may expense pre-stripping costs associated with subsequent pits within a mining complex. Other mining companies may capitalize stripping costs incurred in connection with the production phase.

Mine development costs are amortized using the units-of-production (“UOP”) method based on estimated recoverable ounces in proven and probable reserves. To the extent that these costs benefit an entire ore body, they are amortized over the estimated life of the ore body. Costs incurred to access specific ore blocks or areas that only provide benefit over the life of that area are amortized over the estimated life of that specific ore block or area.

Stripping activity asset. Stripping costs are incurred during the production phase of surface mining in accordance with IFRIC 20 “Stripping costs in the production phase of as surface mine,” whereby a stripping asset is recognized only if all of the following criteria are met:

(i) It is probable that the future economic benefit (improved access to the ore body) associated with the stripping activity will flow to the entity;

(ii) The entity can identify the component of the ore body for which access has been improved; and

| 94 |

(iii) The costs relating to the stripping activity associated with that component can be measured reliably.

The primary components of the ore body on a pit by pit basis, as well as within major pits are identified. Based on these components, stripping activities are analyzed and costs are assigned based on whether they pertained to current inventory production or improved access to future ore bodies (or components of an ore body).

Based on this analysis, Yanacocha allocates the costs associated with improved access to production stripping assets. This allocation is based on the volume of waste and ore extracted in the period compared to expected volume life-of-mine per component of ore body.

Costs allocated to the production stripping activity asset basis in the “waste-to-ore ratio” are subsequently depreciated using the method over the expected useful life of the identified component of the ore body that becomes more accessible as a result of the stripping costs. This depreciation is a production cost and included in the adjustments in inventories.

Mineral Interests. Mineral interests include acquired interests in production, development and exploration stage properties. The mineral interests are capitalized at their fair value at the acquisition date, either as an individual asset purchase or as part of a business combination.

The value of such assets is primarily driven by the nature and amount of mineralized material believed to be contained in such properties. Production stage mineral interests represent interests in operating properties that contain proven and probable reserves. Development stage mineral interests represent interests in properties under development that contain proven and probable reserves. Exploration stage mineral interests represent interests in properties that are believed to potentially contain mineralized material consisting of (i) mineralized material such as inferred material within pits; measured, indicated and inferred material with insufficient drill spacing to qualify as proven and probable reserves; and inferred material in close proximity to proven and probable reserves; (ii) around-mine exploration potential such as inferred material not immediately adjacent to existing reserves and mineralization, but located within the immediate mine area; (iii) other mine-related exploration potential that is not part of measured, indicated or inferred material and is comprised mainly of material outside of the immediate mine area; (iv) greenfield exploration potential that is not associated with any other production, development or exploration stage property, as described above; or (v) any acquired right to explore or extract a potential mineral deposit. Yanacocha’s mineral rights generally are enforceable regardless of whether proven and probable reserves have been established. Yanacocha has the ability and intent to renew mineral interests where the existing term is not sufficient to recover all identified and valued proven and probable reserves and/or undeveloped mineralized material.

Asset Impairment. Yanacocha reviews and evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. An impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. An impairment loss is measured and recorded based on discounted estimated future cash flows. Future cash flows are estimated based on quantities of recoverable minerals, expected gold and other commodity prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans. Existing proven and probable reserves and value beyond proven and probable reserves, including mineralization that is not part of the measured, indicated or inferred resource base, are included when determining the fair value of mine site reporting units at acquisition and, subsequently, in determining whether the assets are impaired. The term “recoverable minerals” refers to the estimated amount of gold or other commodities that will be obtained after taking into account losses during ore processing and treatment. Estimates of recoverable minerals from such exploration stage mineral interests are risk adjusted based on management’s relative confidence in such materials. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of future cash flows from other asset groups. Yanacocha’s estimates of future cash flows are based on numerous assumptions and it is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of recoverable minerals, gold and other commodity prices, production levels and costs and capital are each subject to significant risks and uncertainties.

| 95 |

Income and Mining Taxes and Profit Sharing

Yanacocha accounts for income and mining taxes and legally required profit sharing using the liability method, recognizing certain temporary differences between the financial reporting basis of Yanacocha’s liabilities and assets and the related income tax basis for such liabilities and assets. This method generates a net deferred income tax liability and profit sharing liability or net deferred income tax asset and profit sharing asset for Yanacocha, as measured by the statutory tax and profit sharing rates in effect as enacted. Yanacocha derives its deferred income tax charge or benefit and profit sharing charge or benefit by recording the change in the net deferred income tax liability and profit sharing liability or net deferred income tax asset and profit sharing asset balance for the year, based on Peruvian income and mining tax and profit sharing rates.

Yanacocha’s deferred income tax assets include certain future tax benefits. Yanacocha records a valuation allowance against any portion of those deferred income tax assets when it believes, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset will not be realized.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.

Reclamation and Remediation Costs

Reclamation obligations are recognized when incurred and recorded as liabilities at fair value. The liability is accreted over time through periodic charges to earnings. In addition, the asset retirement cost (“ARC”) is capitalized as part of the asset’s carrying value and amortized over the life of the related asset. Reclamation costs are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. The estimated retirement obligation is based on when spending for an existing environmental disturbance is expected to occur. Yanacocha reviews, on an annual basis, unless otherwise deemed necessary, the reclamation obligation at each mine site.

Future remediation costs for inactive mines are accrued based on management’s best estimate at the end of each period of the costs expected to be incurred at a site. Such cost estimates include, where applicable, ongoing care, maintenance and monitoring costs. Changes in estimates at inactive mines are reflected in earnings in the period an estimate is revised.

Recently Adopted Accounting Pronouncements

Reporting of Amounts reclassified out of Accumulated Other Comprehensive Income

In February 2013, ASC guidance was issued related to items reclassified from Accumulated Other Comprehensive Income (Loss). The new standard requires the disclosure, either in a single note or parenthetically on the face of the financial statements, of: (i) the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and (ii) the income statement line items affected by the reclassification. Adoption of the new guidance, effective for Yanacocha’s fiscal year beginning January 1, 2013, had no impact on the consolidated financial position, results of operations or cash flows.

Disclosures about Offsetting Assets and Liabilities

In November 2011, ASC guidance was issued related to disclosures about offsetting assets and liabilities. The new standard requires disclosures to allow investors to better compare financial statements prepared under U.S. GAAP with financial statements prepared under IFRS. In January 2013, an update was issued to further clarify that the disclosure requirements are limited to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (i) offset in the financial statements or (ii) subject to an enforceable master netting arrangement or similar agreement.

| 96 |

Adoption of the new guidance, effective for the fiscal year beginning January 1, 2013, had no impact on the consolidated financial position, results of operations or cash flows.

Recently Issued Accounting Pronouncements

Presentation of an Unrecognized Tax Benefit

In July 2013, Accounting Standards Codification (“ASC”) guidance was issued related to the presentation of an unrecognized tax benefit when a net operating loss carry forward, a similar tax loss or a tax credit carry forward exists. The updated guidance requires an entity to net its unrecognized tax benefits against the deferred tax assets for all same jurisdiction net operating loss carry forward, a similar tax loss, or tax credit carry forwards. A gross presentation will be required only if such carry forwards are not available or would not be used by the entity to settle any additional income taxes resulting from disallowance of the uncertain tax position. The update is effective prospectively for the Yanacocha’s fiscal year beginning January 1, 2014. Yanacocha is still evaluating the impact of the updated guidance on the consolidated financial position, results of operations or cash flows.

Results of Operations for the Years Ended December 31, 2015 and 2014

Sales

Gold sales. Gold sales decreased by 12%, or US$140 million, from 2014 to 2015, due to a decrease in the number of ounces sold and a decreased average realized price of gold. The decline in ounces sold was proportionate to lower gold production. Gold ounces produced decreased 5.2% due to a decrease in the amount of leach grade material placed on the leach pads compared to prior year as well as lower mill grade and recovery. Yanacocha has not engaged in gold price hedging activities, such as forward sales or option contracts, to minimize its exposure to fluctuations in the price of gold. Production by mine was as follows:

Mine (1) |  | 2015 |  |  | 2014 |
|  | (ounces) |
Cerro Yanacocha |  |  | 52,020 |  |  |  | 30,713 |
Carachugo |  |  | 89,635 |  |  |  | 286,062 |
Maqui Maqui |  |  | 47,712 |  |  |  | 5,669 |
La Quinua |  |  | 728,324 |  |  |  | 647,500 |
Total |  |  | 917,691 |  |  |  | 969,944 |

| (1) | Ounces produced included El Tapado Oeste Pit, Cerro Negro Pit, Marleny Pit production and Verde Bioleach Demonstration Facility.

Costs related to sales

Costs related to sales for the year ending December 31, 2015 and 2014 comprise:

|  | 2015 |  |  | 2014 |
|  | US$(000) |  |  | US$(000) |
Beginning balance of inventories |  |  | 497,669 |  |  |  | 522,596 |
Consumption of supplies |  |  | 210,384 |  |  |  | 246,106 |

| 97 |

Costs applicable to sales. Costs applicable to sales include: (i) operating costs, consisting primarily of direct production costs such as mining and treatment of the ore, which are the most significant components of costs applicable to sales, (ii) workers’ participation profit sharing of 8% of pre-tax profits based on Peruvian labor legislation, (iii) write downs of ore on leach pads to net realizable value expense and (iv) other costs. Costs applicable to sales decreased 19% or US$170 million from 2014 to 2015. Ounces sold decreased 4.5% from 2014 to 2015. Costs applicable to sales per ounce of gold decreased by 14%, from US$949 in 2014 to US$819 in 2015.

Operating costs decreased by 32% from US$674.6 million in 2014 to US$456.0 million in 2015. Operating costs consist primarily of drilling, blasting, loading, hauling and milling costs. These costs decreased in 2015 primarily as a result of lower expenses relating to surface mining costs (lower diesel price and lower repairs and maintenance) and lower heap leaching costs, partially offset by higher milling costs (related to cyanide and lime consumption).

Workers’ profit participation decreased by 18%, from US$35 million in 2014 to US$29 million in 2015. This decrease was directly related to the decrease in Yanacocha’s taxable income from 2014 to 2015. Workers’ profit participation expense is calculated based on taxable net income and in accordance with Peruvian labor legislation.

The portion of leach pad inventory write-downs associated with costs applicable to sales decreased from US$95.8 million in 2014 to US$64.5 million in 2015 due to lower costs of inventory compared to the prior year.

Inventory variation decreased by 39%, from US$70.9 million in 2014 to US$20.9 million in 2015, due to lower stock of ounces at the beginning of year and lower costs per ounce compared to the prior year.

Depreciation, depletion and amortization decreased by 38% from US$360 million in 2014 to US$223 million in 2015. This decrease was attributable principally to lower depreciation associated with assets retirement costs and deferred mine development.

Administrative expenses

Administrative expenses for the years ended December 31, 2015 and 2014 where comprised of:

|  | 2015 |  |  | 2014 |
Management expenses |  | $ | 18,108 |  |  | $ | 19,938 |
Community development expenses and |  |  |  |  |  |  |  |
external affairs |  |  | 6,297 |  |  |  | 15,653 |
Other |  |  | 1,920 |  |  |  | 2,671 |
|  | $ | 26,325 |  |  | $ | 38,262 |

Other operating expense (net)

Other expenses, net for the years ended December 31, 2015 and 2014 were as follows:

|  | 2015 |  |  | 2014 |
Exploration and advance project |  | $ | 64,223 |  |  | $ | 58,880 |
Severance program |  |  | 14,904 |  |  |  | 16,438 |
Disposal of fixed assets |  |  | (135 | ) |  |  | 13,530 |
Other expenses |  |  | (671 | ) |  |  | (6,149 | )
Others, net |  |  | 4,525 |  |  |  | (4,918 | )
|  | $ | 82,846 |  |  | $ | 77,781 |

Advanced projects costs also increased from US$16.5 million in 2014 to US$22 million in 2015. This increase was primarily due to lower activities in 2014 than 2015 for projects such as the Chaquicocha tunnel and Quecher main.

| 98 |

Impairment.

Impairment calculations were conducted for Yanacocha and the Conga project for the 2015 financial statements. Despite the lower market prices for gold and the water first approach at the Conga project, the calculations yielded no write-downs for 2015.

Income tax provision.

Yanacocha’s financial and operating results included income and mining tax expense of US$(602.7) million in 2015 compared to US$30.5 million in 2014. The difference was primarily due to the write-off of the deferred income tax asset of US$510 million.

Net income.

Net income decreased by US$49.9 million, from US$(400.3) million in 2014 to US$(450.2) million in 2015, mainly explained by higher expenses in income tax provision due to a the write-off of the deferred income tax asset and lower revenues from sales due to lower production, offset by reduction in operating costs and the lack of asset impairments during 2015.

Results of Operations for the Years Ended December 31, 2014 and 2013

Sales

Gold sales. Gold sales decreased by 17%, or US$247 million, from 2013 to 2014, due to a decrease in the number of ounces sold and a decreased average realized price of gold. The decline in ounces sold was proportionate to lower gold production. Gold ounces produced decreased 5% due to a decrease in the amount of leach grade material placed on the leach pads compared to prior year as well as lower mill grade and recovery. Yanacocha has not engaged in gold price hedging activities, such as forward sales or option contracts, to minimize its exposure to fluctuations in the price of gold. Production by mine was as follows:

Mine |  | 2014 |  |  | 2013 |
|  | (ounces) |
Cerro Yanacocha |  |  | 30,713 |  |  |  | 16,393 |
Carachugo |  |  | 286,062 |  |  |  | 437,095 |

| 99 |

Costs applicable to sales. Costs applicable to sales include: (i) operating costs, consisting primarily of direct production costs such as mining and treatment of the ore, which are the most significant components of costs applicable to sales, (ii) workers’ participation profit sharing of 8% of pre-tax profits based on Peruvian labor legislation, (iii) write downs of ore on leach pads to net realizable value expense and (iv) other costs. Costs applicable to sales decreased 7% or US$70.9 million from 2013 to 2014. Ounces sold decreased 5.4% from 2013 to 2014. Costs applicable to sales per ounce of gold increased by 2%, from US$974 in 2013 to US$949 in 2014.

Operating costs decreased by 13% from US$776.1 million in 2013 to US$674.6 million in 2014. Operating costs consist primarily of drilling, blasting, loading, hauling and milling costs. These costs decreased in 2014 primarily as a result of lower expenses in supplies, (including a decline in diesel prices beginning in the third quarter of 2014 and minor usage of CAT 785 for advance works in Marleny Pit Mining) and lower personnel expenses due to lower headcount. The volume of commercial tons mined decreased from 161.8 million DST in 2013 to US$118.8 million DST for the year ended December 31, 2014.

Workers’ profit participation decreased by 29%, from US$49 million in 2013 to US$35 million in 2014. This decrease is directly related to the decrease in Yanacocha’s taxable income from 2013 to 2014. Workers’ profit participation expense is calculated based on taxable net income and in accordance with Peruvian labor legislation

The portion of leach pad inventory write-downs associated with costs applicable to sales decreased from US$146 million in 2013 to US$95.8 million in 2014 due to lower costs of inventory compared to the prior year.

Inventory variation decreased by 43%, from US$123.5 million in 2013 to US$70.9 million in 2014, due to lower stock of ounces at the beginning of year and lower costs per ounce compared to the prior year.

Depreciation, depletion and amortization increased by 3% from US$349.7 million in 2013 to US$360 million in 2014. This increase was attributable principally to leach pad inventory write-downs combined higher depreciation associated with assets retirement costs and deferred mine development.

Administrative expenses

Administrative expenses for the year ended December 31, 2014 and 2013 where comprised of:

|  | 2014 |  |  | 2013 |
Management expenses |  | $ | 19,938 |  |  | $ | 17,480 |
Community development expenses and |  |  |  |  |  |  |  |
external affairs |  |  | 15,653 |  |  |  | 46,482 |
Other |  |  | 2,671 |  |  |  | 3,102 |
|  | $ | 38,262 |  |  | $ | 67,064 |

Other operating expense (net)

Other expenses, net for the years ended December 31 were as follows:

|  | 2014 |  |  | 2013 |
Exploration and advance project |  | $ | 58,880 |  |  | $ | 64,510 |
Severance program |  |  | 16,438 |  |  |  | 19,323 |
Disposal of fixed assets |  |  | 13,530 |  |  |  | 6,562 |
Other expenses |  |  | (6,149 | ) |  |  | (8,924 | )
Others, net |  |  | (4,918 | ) |  |  | (3,966 | )
|  | $ | 77,781 |  |  | $ | 77,534 |

Exploration costs decreased by 23%, from US$20.0 million in 2013 to US$15.4 million in 2014. This decrease was attributable principally to lower drilling works in 2014 for Chaquicocha Underground and other minor exploration activities.

Advanced projects costs also decreased from US$44.5 million in 2013 to US$43.5 million in 2014. This decline was primarily due to lower activities in 2014 than in 2013 for projects as Geotechnical Investigation Project and Verde Stage 2 Study project.

Impairment.

The 2014 financial results included an impairment loss of US$541million related exclusively to the Conga project, compared to US$1,038.5 million in 2013 (Yanacocha and Conga). The discount interest rate used in the impairment calculations under the fair value less costs of sale methodology was 8.04% after taxes, which was based on a peer group of mining companies adjusted for Peru country risk. The rate is a “real” versus “nominal” rate as the cash flow models were not escalated for inflation. This discount rate was used for both segments Yanacocha and Conga.

Income tax provision.

Yanacocha’s financial and operating results included income and mining tax expense of US$30.5 million in 2014 compared to US$203.5 million in 2013. The difference was primarily due to Yanacocha’s increased profitability as the result of lower expenses compared to the prior year.

Net income.

As a consequence of the foregoing, net loss decreased by US$175 million, from US$(575) million in 2013 to US$(400) million in 2014.

B. Liquidity and Capital Resources

As of December 31, 2015, Yanacocha had cash and cash equivalents of US$944 million, substantially all of which were held in U.S. Dollars, as compared to US$787 million as of December 31, 2014.

Cash provided by operating activities

Yanacocha’s operations generated a net cash flow from operations of US$275 million in 2015 and US$372.2 million in 2014. The net cash flow from operations in 2015 was 34% or US$101 million lower than in 2014. The decrease was primarily driven by decrease in operating assets as a provision for reclamation and remediation, the write-off of fixed assets and the write-down of ore on leach pads to realizable value.

Cash used in investing activities

Net cash used in investing activities was US$117.3 million in 2015 and US$176 million in 2014.

Yanacocha’s capital expenditures from its formation in 1992 through 2015 have related principally to:

| · | The construction of the Carachugo, Chaquicocha, Maqui Maqui, San José, Cerro Yanacocha, La Quinua Complex (La Quinua, El Tapado and Tapado Oeste), Cerro Negro Este, Western Oxide pits (La Quinua Sur and Cerro Negro Oeste), Eastern Oxide pits (Quecher Norte and Marleny) and Carachugo Alto mining operations;

| · | The construction of two plants at Carachugo and Yanacocha, each of which includes a leach solution processing facility and a smelter;

| · | The construction of four carbon column plants at Cerro Yanacocha and La Quinua;

| · | The acquisition of both new and used mining equipment;

| · | The construction of two dams, the construction of one agglomeration plant at La Quinua, the construction of the Yanacocha Gold Mill, and several expansions of the leach pads located at the Carachugo, Maqui Maqui, Cerro Yanacocha, La Quinua mining operations; and

| 101 |

| · | The construction of Gold Mill Tailing Pipeline and equipment components.

Yanacocha’s capital expenditures from its formation through December 31, 2014 totaled approximately US$5,821 million, including capital expenditures of US$311 million in 2013, US$117 million in 2014 and US$96.2 million in 2015.

In 2015, Yanacocha’s principal capital expenditures included:

| · | US$29 million associated with the initial construction of one water treatment plant at La Quinua;

| · | US$28 million for the storage expansion of La Quinua Tailings and the construction of North Tailings Dump;

| · | US$14 million for equipment components;

| · | US$5 million for equipment upgrade in Verde Bioleach Pilot Plant;

| · | US$3 million for drilling activities in Quecher project;

| · | US$3 million for hydrogeological activities in Western Oxides; and

| · | US$17 million for other minor projects.

Cash used in financing activities

Net cash used in financing activities was US$0 million in both 2015 and 2014. In 2015 and 2014, Yanacocha carried no debt and accordingly had no financing costs.

C. Research and Development

Yanacocha is a mining exploration and production company and does not engage in research and development activities.

D. Trend Information

Other than as disclosed in this Annual Report and the Yanacocha Financial Statements (included elsewhere in this Annual Report), Yanacocha has informed us that it is not aware of any trends, uncertainties, demands, commitments or events which are reasonably likely to have a material effect upon Yanacocha’s net sales or revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information to not necessarily be indicative of future operating results or financial condition.

E. Off-Balance Sheet Arrangements

Yanacocha has informed us that there are no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on Yanacocha’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

CERRO VERDE

Introduction

The following discussion should be read in conjunction with the Cerro Verde Financial Statements as of December 31, 2014 and 2015 and for the years ended December 31, 2013, 2014, and 2015 and the related notes thereto included elsewhere in this Annual Report. The Cerro Verde Financial Statements are prepared and presented in accordance with IFRS as issued by the IASB.

A. Operating Results

Overview

We hold a 19.58% interest in Cerro Verde, which operates an open-pit copper and molybdenum mining complex located 20 miles southwest of Arequipa, Peru. The site is accessible by paved highway. The Cerro Verde mine has been in operation since 1976, and was previously owned by the Peruvian government before its privatization in 1993. Freeport-McMoRan Inc. holds a majority interest in Cerro Verde.

The Cerro Verde mine is a porphyry copper deposit that has leachable oxide and secondary sulfide mineralization, and millable primary sulfide mineralization. The predominant oxide copper minerals are brochantite, chrysocolla, malachite and copper “pitch.” Chalcocite and covellite are the most important secondary copper sulfide minerals. Chalcopyrite and molybdenite are the dominant primary sulfides.

Cerro Verde’s current operations consist of an open-pit copper mine, a 120,000 ton-per-day concentrator and leaching facilities. Leach-copper production is derived from a 39,000 ton-per-day crushed leach facility and a leach system. This leaching operation has a capacity of approximately 200 million pounds of copper per year.

Cerro Verde has sufficient equipment to move an average of 308,000 tons of material per day using a fleet of haul trucks. Copper cathodes and concentrate production are transported approximately 70 miles by truck and rail to the Pacific Port of Matarani for shipment to international markets.

Cerro Verde receives electrical power under long-term contracts with electric utility companies. Water for Cerro Verde’s processing operations comes from renewable sources through a series of storage reservoirs, which Cerro Verde believes will be sufficient to support its currently planned operations.

Presented in the table below are certain summary financial and operating data regarding Cerro Verde for the years ended December 31, 2013, 2014, and 2015:

| (2) | Reserve calculations are derived from the audited financial statements filed by Cerro Verde with the SMV. Cerro Verde used US$2.00 per pound of copper to determine copper reserves as of December 31, 2015. See the Cerro Verde Financial Statements, including the notes thereto, appearing elsewhere in this Annual Report. The calculation or estimation of proven and probable ore reserves for Cerro Verde may differ in some respects from the calculations of proven and probable reserves for us and Yanacocha located elsewhere in this Annual Report. According to Cerro Verde, ore estimates for Cerro Verde are based upon engineering evaluations of assay values derived from samplings of drill holes and other openings. Cerro Verde’s ore estimates include assessments of the resource, mining and metallurgy, as well as consideration of economic, marketing, legal, environmental, social and governmental factors, including projected long-term prices for copper and molybdenum and Cerro Verde’s estimate of future cost trends.

Cerro Verde Mining Royalties

Superintendencia Nacional de Administración Tributaria (“SUNAT”), the Peruvian national tax authority, has assessed mining royalties on ore processed by the Cerro Verde concentrator, which commenced operations in late 2006. These assessments cover the period December 2006 to December 2007 and the years 2008 and 2009. In July 2013, the Peruvian Tax Tribunal, or the “Tax Tribunal,” issued two decisions affirming SUNAT's assessments for the period December 2006 through December 2008. Decisions by the Tax Tribunal end the administrative stage of the appeal procedures for the assessments. In September 2013, Cerro Verde filed judiciary appeals related to the assessments because it continues to believe that its 1998 stability agreement exempts all minerals extracted from its mining concession from royalties, irrespective of the method used for processing those minerals. With respect to the judiciary appeal related to the assessment for the year 2008, on December 17, 2014, the Eighteenth Contentious Administrative Court rendered its decision upholding Cerro Verde’s position and nullifying SUNAT’s assessment and the Tax Tribunal’s resolution (S/.106.4 million). On December 31, 2014, SUNAT and the Tax Tribunal appealed this decision. The court’s position also invalidates all penalties and interest assessed by SUNAT for that period (S/. 139.7 million). On January 29, 2016 the Sixth Superior Justice Court nullified the decision of the Eighteenth Contentious Administrative Court. Cerro Verde will appeal the decision to the Supreme Court.

On October 1, 2013, SUNAT served Cerro Verde with a demand for payment totaling S/.492 million (US$144 million based on exchange rates as of December 31, 2015, including interest and penalties of US$85 million) based on the Tax Tribunal’s decisions for the period December 2006 through December 2008. As permitted by law, Cerro Verde requested and was granted an installment payment program that defers payment for six months and thereafter satisfies the amount via sixty-six equal monthly payments. As of December 31, 2015, Cerro Verde had made payments totaling S/. 219 million (US$64 million based on December 31, 2015 exchange rates) under the installment program, which are presented in the long-term portion of other non-financial assets in the statement of financial position. See Note 7 to the Cerro Verde Financial Statements for further discussion. Based on the results rendered by the Eighteenth Contentious Administrative Court, as described in the previous paragraph, Cerro Verde requested and was granted an injunction, which modified the installment program by excluding the 2008 portion through SUNAT’s resolution provided to Cerro Verde on October 29, 2015.

In July 2013, a hearing on SUNAT’s assessment for 2009 was held, but no decision has been issued by the Tax Tribunal for that year. As of December 31, 2015 the amount of the assessment, including interest and penalties, for the year 2009 was S/247 million (approximately US$72 million based on December 31, 2015 exchange rates). As of December 31, 2015, Cerro Verde estimates that the total exposure associated with mining royalties for the period from December 2006 to December 2013, including accumulated interest and penalties amounted to approximately US$500 million at December 31, 2015 exchange rates.

As of December 31, 2015, no amounts were accrued for these assessment or for the amounts paid under the installment and its external legal advisors believe Cerro Verde’s 1998 stability agreement exempted it from these royalties and believes that the resolution will be favorable to Cerro Verde and any payment should be recoverable.

Critical Accounting Policies

Cerro Verde has furnished us with a discussion of its critical accounting policies and methods used in the preparation of its financial statements. Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties and could potentially impact results under different assumptions and conditions. Note 2 to the Cerro Verde Financial Statements includes a summary of the significant accounting policies and methods used in the preparation of the Cerro Verde Financial Statements. The following is a brief discussion of the identified critical accounting policies and the estimates and judgments made by Cerro Verde.

Estimates of Ore Reserves and Resources

Ore reserves are estimates of the ore quantity that can be economically and legally extracted from the mine properties. Cerro Verde estimates its ore reserves based on information compiled by individuals qualified in reference to geological data about the size, depth and form of the ore body, which requires complex judgments to interpret the data.

The estimation of recoverable reserves is based on factors such as estimated exchange rates, commodity prices, future requirements of capital and production costs, together with geological hypotheses and judgments made when estimating the size and quality of ore. Revisions in reserve or resource estimates may have an impact on the value of mining properties, property, plant and equipment, provisions for cost of mine closure, recognition of assets for deferred taxes and depreciation and amortization of assets.

UOP Depreciation

Estimates of recoverable reserves are used in determining the depreciation and amortization of mine assets. This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life of mine production. Each item’s life, which is assessed annually, takes into account its physical life limitations and the present assessments of economically recoverable reserves. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves that may be recovered.

Inventories

Net realizable value tests are performed at least annually and represent the estimated future sales price of the product based on prevailing spot metals prices, less estimated costs to complete production and bring the inventory to sale. Additionally, in calculating the net realizable value of Cerro Verde’s long-term stockpiles, management also considers the time value of money.

Mill and leach stockpiles generally contain lower grade ores that have been extracted from the ore body and are available for copper recovery. For mill stockpiles, recovery is through milling and concentrating. For leach stockpiles, recovery is through exposure to acidic solutions that dissolve copper and deliver it in solution form to extraction processing facilities.

Because it is generally impracticable to determine copper contained in mill and leach stockpiles by physical count, reasonable estimation methods are employed. The quantity of material delivered to mill and leach stockpiles is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated copper grades of material delivered to mill and leach stockpiles.

Expected copper recovery rates for mill stockpiles are determined by metallurgical sampling. The recoverable copper in mill stockpiles, once entered into the production process, can be produced into copper concentrate almost immediately.

Estimated copper recovery rates for leach stockpiles are determined using small-scale laboratory tests, historical trends and other factors. Ultimate recovery of copper contained in leach stockpiles can vary significantly depending on several variables, including the type of copper recovery, mineralogy and particle size of the rock. Processes and recovery rates are monitored continuously, and recovery rates are adjusted periodically as additional information becomes available and as related technology changes.

| 106 |

Mine Closure Provision

Cerro Verde assesses its mine closure provision annually. It is necessary to make estimates and assumptions in determining this provision, including cost estimates of activities that are necessary for the rehabilitation of the site, technological and regulatory changes, and interest rates and inflation rates. As discussed in Note 2.2(i) to the Cerro Verde Financial Statements, estimated changes in the fair value of the mine closure provision or the useful life of the related assets are recognized as an increase or decrease in the book value of the provision and related ARC in accordance with IAS 16, “Property, Plant and Equipment.” If any change in the estimate results in an increase to the mine closure provision and related ARC, Cerro Verde will consider whether or not this is an indicator of impairment of the assets and apply impairment tests in accordance with IAS 36, “Impairments of Assets.”

Impairment of Long-lived Assets

Cerro Verde has determined that its operation consists of one cash generating unit, which is the operation as a whole. Therefore, the Cerro Verde operation is evaluated annually to determine if there are any impairment indicators. If any such indication exists, Cerro Verde makes an estimate of the recoverable amount, which is the greater of the fair value less costs to sell and the value in use. These assessments require the use of estimates and assumptions, such as long-term commodity prices, discount rates, operating costs and others.

Fair value is defined as the amount that would be obtained from the sale of the asset in an arm’s-length transaction between willing and knowledgeable parties. The fair value of assets is generally determined as the current value of future cash flows derived from the continuous use of the asset, which includes estimates, such as the cost of future expansion plans and eventual disposal, while applying assumptions that an independent market participant may take into account. The cash flows are discounted by applying a discount rate that reflects the current market, the time value of money and risks specific to the asset. See Note 2.2(g) to the Cerro Verde Financial Statements for further discussion.

Contingencies

By their nature, contingencies will only be resolved when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential quantum of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

Stripping cost

In accordance with IFRIC 20, “Stripping Cost in the Production Phase of a Surface Mine,” stripping costs incurred in the production phase are capitalized as a component of property, plant and equipment if the stripping activity improves access to the ore body or enhances an existing asset. See Note 9 to the Cerro Verde Financial Statements for further discussion. The stripping activity asset is subsequently amortized using the UOP method.

Results of Operations for the Years Ended December 31, 2015 and 2014

Net sales. Net sales, including and mark-to-market adjustments for pounds of copper pending settlement, decreased by 24%, from US$1,467.1 million in 2014 to US$1,115,6 million in 2015, principally due to a decrease in average realized copper prices during 2014 partially offset by higher volume of copper sold. The following table reflects the average realized price and volume sold of copper (both cathode and concentrate) during the years ended December 31, 2014 and 2015:

| 107 |

|  | Year ended December 31, |  |  |  |
|  | 2014 |  |  | 2015 |  |  | Variation |
Average price |  |  |  |  |  |  |  |  |  |  |  |
Copper (US$ per ton) |  | $ | 6,452 |  |  |  | 4,518 |  |  |  | -30 | %
Volume sold |  |  |  |  |  |  |  |  |  |  |  |
Copper (in tons) |  |  | 227,402 |  |  |  | 246,913 |  |  |  | 9 | %

Average realized copper prices per ton decreased from US$6,452 in 2014 to US$4,518 in 2015. The volume of copper sold increased from 227,402 tons in 2014 to 246,913 tons in 2015, due to an increase in the volume of copper concentrates sold associated with Cerro Verde’s new concentrator plant that commenced operation in September 2015. The combined effect of these changes resulted in a US$351.5 million decrease in income from sales of copper in 2015 compared to 2014.

Total costs of sales of goods. Total costs of sales of goods increased from US$797.5 million in 2014 to US$862.0 million in 2015, due mainly to the net effect of the following:

(a) Material and supplies consumption cost increased by 9%, from US$333.5 million in 2014 to US$364.2 million in 2015, mainly due to increased consumption of supplies for Cerro Verde’s new concentrator plant.

(b) Labor costs, including workers’ profit sharing, decreased by 15%, from US$171.6 million in 2014 to US$146.4 million in 2015, mainly due to lower profit sharing in 2015 as compared to 2014 as a result of lower profits;

(c) The variation of in process inventories increased from US$70.5 million in 2014 to US$118.3 million in 2015 as a result of higher material due to the new concentrator plant and the current mining plan of processing high grade concentrates first and then low grade concentrates;

(d) Depreciation and amortization costs increased by 48%, from US$165.0 million in 2014 to US$244.5 million in 2015, mainly due to depreciation associated with Cerro Verde’s new concentrator plant;

(e) Repair and maintenance services increased by 9%, from US$87.5 million in 2014 to US$95.1 million in 2015; and

(f) Energy costs increased by 29%, from US$91.8 million in 2014 to US$118.0 million in 2015, mainly due to Cerro Verde’s new concentrator plant.

Total operating expenses. Operating expenses increased by 43%, from US$57.8 million in 2014 to US$82.8 million in 2015, due mainly to changes in the following components:

(a) Selling expenses increased by 4%, from US$54.2 million in 2014 to US$56.2 million in 2015, mainly due to higher copper concentrate sales during 2015; and

(b) Other expenses increased by US$23.0 million in 2015 mainly due to costs associated with commencing operations at Cerro Verde’s new concentrator plant.

Income tax. Income tax expense, including current and deferred expense, decreased by 81%, from an expense of US$238.5 million in 2014 to an expense of US$46.2 million in 2015. Net current income tax expense (including mining taxes) decreased by US$262.1 million due to lower taxable income and an increase in deferred tax expense by 69.8 million (mainly related to a temporary tax difference associated with the depreciation of fixed assets).

Net income. As a result of the foregoing, net income decreased by 9%, from US$377.6 million in 2014 to US$33.3 million in 2015. As a percentage of net sales, net income was 3% in 2015, compared with 26% in 2014.

Results of Operations for the Years Ended December 31, 2014 and 2013

Net sales. Net sales, including and mark-to-market adjustments for pounds of copper pending settlement, decreased by 19%, from US$1,811.5 million in 2013 to US$1,467.1 million in 2014, principally due to a decrease in average realized copper prices during 2014 and lower volume of copper sold. The following table reflects the average realized price and volume sold of copper (both cathode and concentrate) during the years ended December 31, 2013 and 2014:

|  | Year ended December 31, |  |  |  |
|  | 2013 |  |  | 2014 |  |  | Variation |
Average price |  |  |  |  |  |  |  |  |  |  |  |
Copper (US$ per ton) |  | $ | 7,137 |  |  | $ | 6,452 |  |  |  | -10 | %
Volume sold |  |  |  |  |  |  |  |  |  |  |  |
Copper (in tons) |  |  | 253,828 |  |  |  | 227,402 |  |  |  | -10 | %

Average realized copper prices per ton decreased from US$7,137 in 2013 to US$6,452 in 2014. The volume of copper sold decreased from 253,828 tons in 2013 to 227,402 tons in 2014, due to a decrease in the volume of copper concentrates sold. The combined effect of these changes resulted in a US$344.4 million decrease in income from sales of copper in 2014 compared to 2013.

Total costs of sales. Total costs of sales increased from US$795.1 million in 2013 to US$797.5 million in 2014, due mainly to the net effect of the following:

(a) Material and supplies consumption cost increased by 3%, from US$324.9 million in 2013 to US$333.5 million in 2014, mainly due to increased consumption of supplies in the mine area (associated with haulage and mining equipment);

(b) Labor costs, including workers’ profit sharing, decreased by 20%, from US$215.4 million in 2013 to US$171.6 million in 2014, mainly due to a charge of US$35.2 million related to bonuses paid to employees in connection with the newly signed union workers’ collective labor agreement in 2013, and lower profit sharing in 2014 as compared to 2013 due to lower profits;

(c) The variation of in process inventories increased from US$57.9 million in 2013 to US$70.5 million in 2014 as a result of the current mining plan of processing high grade concentrates first and then low grade concentrates;

(d) Depreciation and amortization costs increased by 52%, from US$109.3 million in 2013 to US$166.6 million in 2014, mainly due to amortization of deferred stripping assets by US$44.9 million;

(e) Repair and maintenance services decreased by 5%, from US$91.9 million in 2013 to US$87.5 million in 2014; and

(f) Energy costs increased by 22%, from US$73.9 million in 2013 to US$90.2 million in 2014, mainly due to an increase in the unit cost per kilowatt during 2014 as compared to 2013.

Total operating expenses. Operating expenses decreased by 15%, from US$68.3 million in 2013 to US$57.8 million in 2014, due mainly to changes in the following components:

(a) Selling expenses decreased by 21%, from US$68.4 million in 2013 to US$54.2 million in 2014, due mainly to lower copper sales during 2014; and

D. Employees

As of December 31, 2015 we, including our subsidiaries and Coimolache, had 3,419 employees (including 45 employees from our mining trainee program). In addition, we have entered into arrangements with independent contractors which employed 11,668 workers at our operations. We have sought to strengthen our workforce by implementing a qualifications-based hiring policy and, with respect to employees working in the mines, reducing the average age of the workforce. As of December 31, 2015, the average tenure of Buenaventura’s permanent laborers was approximately 8 years.

Of the 2,634 permanent employees employed by Buenaventura and its subsidiaries directly, approximately 39% are members of 11 different labor unions (including four unions for clerical workers, seven unions for laborers), which represent all clerical workers and laborers in collective bargaining negotiations with us. There are also five unions for workers employed by independent contractors that were formed over the last six years in our mines at Uchucchacua, Orcopampa, La Zanja, Julcani and El Brocal.

Each of the labor unions is a company-based union with an affiliation to a national union. Administrative personnel are not represented by unions. Labor relations for unionized and non-unionized employees in our production facilities, including compensation and benefits, are governed by collective bargaining agreements, the terms and length of which are negotiated throughout the year as the various collective bargaining agreements come up for renewal. These collective bargaining agreements are typically one year in length and set wages for the applicable period, including increases as negotiated and certain other employee benefits, such as overtime, bonuses and family benefits.

During 2015, we experienced a strike at one of our mines. Between May and June 2015, we had a strike at the Uchucchacua mine for 29 days that was staged by workers’ and contractors’ unions claiming unsuitable working conditions. The Peruvian Ministry of Labor declared the Uchucchacua workers’ work stoppages illegal. In June of 2015, El Brocal experienced two days of work stoppage at its concentrator plant in Huaraucaca in connection with the negotiation of salaries and the collective bargaining agreement.

Compensation received by our employees includes salary, other cash payments (such as overtime, vacation pay and bonuses including, but not limited to, high altitude and underground mining bonuses) and non-cash benefits. Non-cash benefits include medical insurance, life insurance and training programs for workers and administrative staff. For mine and processing plant workers, benefits also include transportation services, meals or food allowances, education for children of our employees and housing, hospitals and a full range of social services for our permanent employees and their families at town sites near our mines in compliance with mining regulations. We voluntarily provide power, water and sewage services for the camp and houses of the workers as well as for certain towns nearby. In addition, pursuant to a profit-sharing plan mandated by Peruvian labor legislation, employees of mining companies in Peru are entitled to receive the Employee Profit Sharing Amount equivalent to 8% of the annual pre-tax profits of their employer, 50% of such profits to be distributed based on the number of days each employee worked during the preceding year and the remaining 50% of such profits to be distributed based on the aggregate annual salary of each employee. Effective January 1, 1997, the annual payment to each employee under the profit sharing plan cannot exceed 18 times such employee’s monthly salary, and any difference between the Employee Profit Sharing Amount and the aggregate amount paid to employees must be contributed by us to FONDOEMPLEO, a fund established to promote employment and employee training.

Under Peruvian law, we may dismiss workers for cause by following certain formal procedures. We may dismiss a worker without cause, provided that we pay such worker a layoff indemnification in an amount equal to one and a half month’s salary for each full year worked plus the pro rata portion for any uncompleted year, not to exceed in the aggregate 12 months’ salary. Several decisions adopted by the Peruvian Constitutional Court, holding that an employee is entitled for reinstatement if no cause for dismissal is expressed by the employer or for failure to present evidence supporting the employer’s grounds, have limited our ability to dismiss a worker without cause. However, all employees are entitled to a severance payment upon termination of their employment, regardless of the reason for such termination, equal to approximately one month’s salary for each full year worked plus the pro rata portion for any uncompleted year. Pursuant to the Peruvian labor laws enacted in 1992, we deposit funds for severance payments in a bank account selected by each employee and for the benefit of such employee, in both May and November of each year.

Our permanent employees receive the benefit of one of two types of pension arrangements. All workers can choose to enroll in the a public pension fund managed by the state (the “ONP” system) or in a private pension funds (the “AFP” system). We are required to withhold from each of the salaries of the employees enrolled in the ONP system 13% of such employee’s salary, and pay such amount to the ONP system and withhold from the salary of each employee enrolled in the AFP system approximately 12.5% of such employee’s salary, and pay such amounts to the respective AFP (exact amount varies from one AFP to another). Additionally, for workers involved in mining and metallurgical processes, an additional 2% is withheld from their salaries, and we contribute an additional 2 percent to increase their pension funds. We have no liability for the performance of these pension plans. In addition, our independent contractors are responsible for covering severance and pension payments with respect to their employees.

In addition, we pay ESSALUD 9% of our total payroll for general health services for all permanent employees. Further, Law No. 26790 also requires us to provide private insurance representing an average payment equal to 1.30 percent of the payroll of covered employees for employment-related incapacity and death for blue collar employees and other employees exposed to mining-related hazards.

B. Related Party Transactions

Except as otherwise disclosed herein, no director, senior officer, principal shareholder or any associate or affiliate thereof had any material interest, direct or indirect, in any transaction since the beginning of our last financial year that has materially affected us, or in any proposed transaction that would materially affect us. Except as otherwise disclosed herein, we have entered into no transactions with parties that are not “related parties” but who would otherwise be able to negotiate terms not available on an arm’s-length basis. From time to time in the ordinary course of business, we enter into management, exploration, mine construction, engineering and employment contracts with joint venture companies in which one or more of our direct or indirect subsidiaries holds equity or partnership interests.

The compensation of our key executives (including the related income taxes we assumed in connection therewith) totaled US$2.8 million in 2014 and US$4.8 million in 2015.

Chaupiloma is the legal owner of the mineral rights operated by Yanacocha and receives a 3% royalty based on quarterly sales, after deducting refinery and transportation costs. Royalties amounted to US$44.2 million, US$36.9 million and US$32.4 million in 2013, 2014 and 2015, and are presented as royalty income in our consolidated statements of income.

Condesa did not receive a cash dividend from Yanacocha in 2013, 2014 or 2015.

We did not receive a cash dividend from Cerro Verde in 2013, 2014 or 2015.

| 118 |

We received cash dividends from Coimolache of approximately US$9.8 million in 2013, US$12.9 million in 2014 and US$6.7 million in 2015.

In March 2002, BISA signed a technical service agreement with Yanacocha to perform a number of specialized activities and services. Pursuant to the agreement, the services performed relate to the construction of mining projects and include completion of analysis and studies, work plan design, and functions related to planning, monitoring and administrating the infrastructure projects required by Yanacocha in its operations.

In November 2000, Conenhua signed an agreement with Yanacocha for the construction and operation of a 220 kW transmission line between Trujillo and Cajamarca, a 60 kW transmission line between Cajamarca and La Pajuela, and the Cajamarca Norte substation; this agreement also encompassed activities necessary to enlarge the Trujillo substation. Pursuant to this contract, the construction work was completed in October 2001. Concurrently, we and Yanacocha signed a 10-year agreement covering electric energy transmission and infrastructure operation beginning in November 2001. In exchange for us operating and managing the transmission project, Yanacocha pays a fee of US3.7 million with annual maturities. The annual revenues for these services amounted to approximately US$0.9 million in each of 2013, 2014 and 2015.

Dividends and Dividend Policy

We can distribute three kinds of dividends: (i) cash dividends, which are paid out of our net distributable income for each year, (ii) stock dividends that are akin to stock splits rather than distributions of earnings, which are issued for the purpose of adjusting the book value per share of our stock, and (iii) stock dividends for the purpose of capitalizing profits, in each case as described in more detail below. All shares outstanding and fully paid are entitled to share equally in any dividend declared based on the portion of our capital represented by such share. Shares of capital stock which are only partially paid participate in a dividend or distribution in the same proportion that such shares have been paid at the time of the dividend or distribution. No cash dividend may be declared in respect of a given year unless we have earned net distributable income in respect of such year. However, we may declare dividends during the year. We may make interim provisional payments to shareholders in respect of net distributable income for the current fiscal year, which are referred to as “provisional dividends,” as explained below.

| 119 |

The Board of Directors, following the end of each fiscal year, makes a recommendation at the annual obligatory shareholders’ meeting regarding the amount and timing of payments, if any, to be made as dividends on our Common Shares and Investment Shares.

The dividend policy establishes that Buenaventura will distribute an annual cash dividend of at least 20% of net income generated by majority-owned operations and subsidiaries. In the case of Buenaventura’s Associates (Coimolache, Cerro Verde and Yanacocha), 20% of attributable to Buenaventura’s net income will be included if they distribute cash dividends to Buenaventura. In principle there are two kinds of dividend payments: interim dividends, which are approved by the Board and are generally paid during the fourth quarter of the year, and the final dividend payment, which will be paid in accordance with the general shareholders’ meeting resolutions. However, the amount and timing of such payments is subject to the final approval at such annual obligatory shareholders’ meeting and Board meeting, as well as to the availability of earnings to distribute. According to the Peruvian Companies Law, holders of at least 20% of the total Common Shares outstanding can request a dividend of 50% or less of the previous year’s after-tax profits, net of amounts allocated to the legal reserve.

Available earnings are subject to the following priorities. First, the mandatory employee profit sharing of 8% of pre-tax profits (which may differ from pre-tax profits determined under IFRS due to different depreciation treatment and different adjustments of non-taxable income and/or non-deductible expenses) is paid. Next, remaining earnings are taxed at the standard corporate income tax rate, which has been 30 percent since January 1, 2004. Such rate has been reduced to 28% for 2015 and 2016, to 27% for 2017 and 2018 and to 26% for 2019 and thereafter. Not less than 10 percent of such after-tax net profits must then be allocated to a legal reserve, which is not available thereafter except to cover future losses or for use in future capitalizations. Amounts reserved are nevertheless included in taxable income. The obligation to fund this reserve continues until the reserve constitutes 20% of the paid-in share capital. In addition, the holders of Common Shares can agree to allocate any portion of the net profits to any special reserve. The remainder of the net profits is available for distribution to shareholders. Any dividend approved by a shareholders’ meeting after December 31, 2002 has been subject until 2014 to an additional withholding tax at the rate of 4.1% of the total amount of dividends distributed to shareholders who are either (i) individuals, whether domiciled or non-domiciled in Peru, or (ii) non-domiciled companies or entities. For dividends paid out from our accumulated net profits after December 31, 2014, such withholding rate has been increased to 6.8% for 2015 and 2016, to 8.0% for 2017 and 2018 and to 9.3% for 2019 and thereafter. Dividends paid to domiciled companies or entities are not subject to such withholding tax. If any tax or other governmental charge will become payable by Scotiabank Peru, as custodian, the Depositary or us with respect to any ADR or any deposited securities represented by the ADSs evidenced by such ADR, such tax or other governmental charge will be payable by the owner or beneficial owner of such ADR to the Depositary.

Dividends on issued and outstanding Common Shares and Investment Shares are distributed in accordance with the proportion of the total capital represented by such respective shares. Dividends are distributed pro rata in accordance with the number of Common Shares or Investment Shares. Accordingly, any dividend declared would be apportioned 99.73% to the holders of Common Shares and 0.27% to the holders of Investment Shares. This proportion will not change in the future except and to the extent holders of Common Shares and Investment Shares exercise their preemptive rights disproportionately in any future issuance of Common Shares and Investment Shares, or we issue Common Shares without preemptive rights in accordance with Article 259 of the Peruvian Companies Law.

Holders of Common Shares and Investment Shares are not entitled to interest on dividend payments.

Holders of ADRs are entitled to receive dividends with respect to the Common Shares underlying the ADSs evidenced by such ADRs, subject to the terms of the related Amended and Restated Deposit Agreement, to the same extent as owners of Common Shares.

To the extent that we declare and pay dividends on the Common Shares, owners of the ADSs on the relevant record date are entitled to receive the dividends payable in respect of the Common Shares underlying the ADSs, subject to the terms of the Amended and Restated Deposit Agreement. Cash dividends are paid to the Depositary in Soles and, except as otherwise described under the Amended and Restated Deposit Agreement, are converted by the Depositary into U.S. Dollars and paid to owners of ADRs net of currency conversion expenses. Under the Amended and Restated Deposit Agreement, the Depositary may, and will if we so request, distribute stock dividends in the form of additional ADRs evidencing whole ADSs resulting from a dividend or free distribution of Common Shares by us received by the Depositary. Cash dividends paid with respect to the Common Shares and amounts distributed with respect to ADSs have been subject until 2014 to a Peruvian withholding income tax of 4.1 percent. Such withholding rate has been increased for dividends paid out from our accumulated net profits after December 31, 2014 to 6.8% for 2015 and 2016, to 8.0% for 2017 and 2018 and to 9.3% for 2019 and thereafter. See “Item 10. Additional Information – E. Taxation – Peruvian Tax Considerations.”

| 120 |

We issue stock dividends for value per share of our stock. The book value of our share capital is based on the nominal (par) value of each share but is adjusted to account for inflation; thus, in inflationary periods, our book value will increase while the nominal value will remain constant. To adjust the book value of each share to equal or approximate the nominal value, we periodically issue new shares that are distributed as stock dividends to each existing shareholder in proportion to such shareholder’s existing holdings, unless it increases the nominal value of the existing shares. These stock dividends (which under the Peruvian income tax law are not considered dividends) do not change a stockholder’s percentage of interest in us. In addition, we may from time to time capitalize profits and, in such case, we have to distribute stock dividends representing the profits capitalized.

Dividends not collected within ten years will be retained by us, increasing our legal reserve, and the right to collect such dividends will expire.

Under Peruvian law, each company may make formal cash distributions only out of net distributable income (calculated on an individual, unconsolidated basis and demonstrated by a statement of financial position at any given time). We, however, may pay provisional dividends. Payment of provisional dividends will be approved on the basis of financial statements which show the existence of net distributable income obtained during the current fiscal year. If, following such an interim provisional payment, we suffer a loss or if we finish the fiscal year with a net income that is lower than the amount of provisional dividends paid during such fiscal year, we could legally require all shareholders (including holders of ADRs) to return such payment to us with interest. However, it has been and continues to be our policy not to require shareholders to return such payment of provisional dividends, but rather to cover such contingency through a “dividends paid in advance” account to be offset by future net distributable income.

The following table sets forth the amounts of interim and final cash dividends and the aggregate of cash dividends paid with respect to the years 2012 to 2015. Dividends with respect to the years 2012 to 2015 were paid per Common Share and ADS.

Non-controlling Shareholders

Law No. 28370, published on October 30, 2004, included in the Peruvian Companies Law certain provisions for the protection of non-controlling shareholders that were formerly contained in Law No. 26985, which had been abrogated. Legislative Decree No. 1061, effective since June 29, 2008, Law No. 29782, effective since July 29, 2011, and most recently Law No. 30050, effective since June 27, 2013, have abrogated or amended certain of these provisions. Pursuant to Article 262-A of the Peruvian Companies Law, we will furnish on our website and on the SMV’s website, upon the earlier to occur of (1) sixty days after the Annual Obligatory Shareholders’ Meeting, or (2) the expiration of the three-month period after the end of the prior fiscal year in which such Annual Obligatory Shareholders’ Meeting is required to be held, the information regarding total number and value of any shares not claimed by shareholders, the name of such shareholders, the share quote in the securities market for such shares, the total amount of uncollected dividends and where shares and dividends pending claim are available for the non-controlling shareholders. Article 262-B describes the procedure to request share certificates and/or dividends and that the holder of the shares can instruct us to deposit the dividends in a specific bank account. Article 262-F describes the procedure for handling any claim that the non-controlling shareholders may file, such claims to be resolved by the SMV.

B. Memorandum and Articles of Association

Organization and Register

We were formed on September 7, 1953 by public deed as a Peruvian sociedad anónima. However, in May of 1998, our By-laws were changed to conform with the new Peruvian Companies Law. The term of existence is indefinite and our principal place of business is Lima, Peru. We are registered under file number 02136988 at the Companies Registry of Lima.

We are managed by the General Meeting, the Board of Directors and the management.

Objectives and Purposes

Our legal purpose, as set forth in our Articles of Association and By-laws, is to engage in mining operations and related activities either directly or through majority-owned subsidiaries and controlled companies. Likewise, we may hold shares of companies performing mining operations.

Directors

The Board of Directors, which must be comprised of seven members, is elected at the Annual Obligatory Meeting. Any changes in the Board of Directors require the approval of the shareholders. The removal of the Board of Directors must be approved at a shareholders’ meeting, attended by holders of 75% of the Common Shares in the first summons and 70% of the Common Shares in the second summons, by resolution approved by at least two thirds of the total number of Common Shares outstanding. In the case of resignation of Directors, the Board of Directors may appoint substitute Directors who will serve until the next shareholders’ meeting.

Directors are elected as a group for a term of three years and may be reelected indefinitely. Pursuant to Article 29 of our By-laws, Directors are not required to be shareholders. The Board of Directors, in its first meeting after the Annual Obligatory Meeting during which elections are held, must choose from among its members a Chairman and a Vice Chairman. The Peruvian Companies Law requires that all companies (sociedades anónimas) provide for the representation of non-controlling shareholders on their Boards of Directors. To that effect, each of our Common Shares gives the holder the right to as many votes as there are directors to be elected. Each holder may pool his votes in favor of one person or distribute them among various persons. Those candidates for the Board who receive the most votes are elected directors.

| 123 |

The Board of Directors meets when called by the Chairman of the Board, who is appointed by the Board. The Board of Directors is validly convened when all Directors are present and unanimously agree to carry out the meeting for the purpose of transacting the business that has been proposed. Pursuant to Article 177 of the Peruvian Companies Law, Directors may be jointly and severally liable to us, the shareholders and third parties for their actions if they act with willful misconduct, gross negligence or abuse their powers. In addition, Article 3 of Law No. 29720, which has been in force since June 26, 2011, as amended by Law No. 30050 in force since June 27, 2013, provides that directors and managers are liable for economic damages or any other kind of damages caused to us by any transaction we may enter into with them.

Our By-laws do not contain any provisions related to a director’s power to vote on matters in which the director is materially interested. However, Article 180 of the Peruvian Companies Law requires a director with an interest that conflicts with an interest of ours on a specific matter to disclose such interest to us and abstain from participating in the deliberation and decision of the said matter. A director that contravenes such requirement is liable for the damages suffered by us and can be removed by the Board of Directors or a shareholders’ meeting upon the request of any shareholder or any member of the Board.

Our By-laws also do not contain any provisions with respect to the power of the Directors to vote upon matters relating to their own compensation. Nevertheless, Article 30 of the By-laws requires that the Board of Directors receive compensation of no more than 4% of the profits of each fiscal year after making deductions for workers’ profit sharing, taxes, reinvestment of profits for tax benefits and legal reserves. This amount will be submitted for ratification by the General Meeting during the annual obligatory meeting, at which time it approves the statement of financial position, taxes, reinvestment of profits for tax benefits and legal reserves.

Our By-laws contain no provision relating to the directors’ power to borrow from us. However, Article 179 of the Peruvian Companies Law provides that directors of a company may enter into an agreement with such company only if the agreement relates to operations the company performs in the regular course of business and in an arms-length transaction. Furthermore, a company may provide a loan to a director or grant securities in his favor only in connection with operations that the company usually performs with third parties. Agreements, credits, loans or guarantees that do not meet the requirements set forth above require prior approval from at least two thirds of the members of the company’s Board of Directors. Directors are jointly liable to the company and the company’s creditors for contracts, credit, loans or securities executed or granted without complying with Article 179 of the Peruvian Companies Law. In addition, as mentioned above, Article 3 of Law No. 29720 as amended provides that directors and managers are liable for economic or other damages that they may cause because of the approval of resolutions that favor such director’s, or a related party’s, interest instead of the company’s, when: (i) one of the parties involved in the transaction is a company whose shares are listed in the local stock exchange, as in our case; (ii) the shareholder controlling such listed company also controls the other party involved in the transaction; and (iii) the transaction is not made under arm’s-length conditions and represents at least 10% of such Company’s assets.

Neither our By-laws nor the Peruvian Companies Law contain age limit requirements for the retirement or non-retirement of directors.

Shares and Voting Rights

We have two classes of shares, the Common Shares and the Investment Shares. The Common Shares represent 100% of our outstanding share capital. The Investment Shares have no voting rights and are not, under Peruvian law and accounting rules, characterized as share capital. The Common Shares and the Investment Shares may be either physical share certificates in registered form or book-entry securities in the CAVALI ICLV S.A. book-entry settlement system, also in registered form.

Holders of Common Shares are entitled to one vote per share, with the exception of the election of the Board of Directors, where each such holder is entitled to one vote per share per nominee. Each holder’s votes may be cast all for a single nominee or distributed among the nominees at the holder’s discretion. Holders of Common Shares may attend and vote at shareholders’ meetings either in person or through a proxy. Additionally, holders of Common Shares have the right to participate in the distribution of dividends and shareholder equity resulting from liquidation. Our By-laws do not establish a maximum time limit for the payment of the dividends. However, according to Article 232 of the Peruvian Companies Law, the right to collect past-due dividends in the case of public companies that are sociedades anónimas abiertas, as we are, expires at 10 years from the date on which the payment was due in accordance with the dividend declaration.

| 124 |

Our share capital may be increased by holders of Common Shares at a shareholders’ meeting. Capital reductions may be voluntary or mandatory and must be approved by holders of Common Shares at a shareholders’ meeting. Capital reductions are mandatory when accumulated losses exceed 50 percent of capital to the extent such accumulated losses are not offset by accumulated earnings and capital increases within the following fiscal year. Capital increases and reductions must be communicated to the SMV, the Lima Stock Exchange and the SUNAT and published in the official gazette El Peruano and in a widely circulated newspaper in the city in which we are located.

The Investment Shares do not represent our stock obligations. Holders of Investment Shares are neither entitled to exercise voting rights nor to participate in shareholders’ meetings. However, Investment Shares confer upon the holders thereof the right to participate in the dividends distributed according to their nominal value, in the same manner as Common Shares.

Changes in the Rights of Shareholders

Our By-laws do not contain special provisions relating to actions necessary to change the rights of holders of the classes of shares. However, Article 88 of the Peruvian Companies Law establishes that all shares of a same class must have the same rights and obligations, and that if we decide to establish different rights and obligations we must create a different class of shares, which creation will be agreed upon by the General Meeting in accordance with the requirements for modification of the By-laws. The Common Shares are the only class of shares representing 100% of our share capital, and, therefore, each Common Share has the same rights and obligations of each other Common Share. These requirements are described under “—Shares and Voting Rights” above.

The rights of any class of shares may not be reduced except in accordance with the Peruvian Companies Law.

Shareholders’ Meetings

Pursuant to Peruvian law and our By-laws, the Annual Obligatory Meeting must be held during the three-month period after the end of each fiscal year. Additional General Meetings may be held during the year. Because we are a sociedad anónima abierta, we are subject to the special control of the SMV, as provided in Article 253 of the Peruvian Companies Law. Shareholders’ meetings are convened by the Board of Directors when deemed convenient for us or when it is requested by the holders of at least 5% of the Common Shares, provided that such Common Shares do not have their voting rights suspended. If, at the request of holders of at least 5 percent of the Common Shares, the shareholders’ meeting is not convened by the Board of Directors within 15 business days of the receipt of such request, such holders of at least 5 percent of the Common Shares may request a notary public or a judge to convene the meeting. The Board is deemed to have implicitly refused to convene the meeting if the Board (a) does not convene a shareholders’ meeting within 15 business days of receipt of the request, (b) suspends or amends the terms of the agenda or in any other way amend the terms of the summons already made upon the request of at least 5% of the Common Shares or (c) schedules the shareholders’ meeting more than 40 days after the date on which the summons is published. The notary public or the judge of the domicile of the company shall call for the shareholders meeting. Resolución CONASEV No. 111-2003-EF-94.10, as amended by Resolución CONASEV No. 078-2010-EF/94.01.1, approved provisions related to the right of the non-controlling shareholders to obtain information regarding a sociedad anónima abierta such as ourselves. Notwithstanding the notice requirements as described in the preceding two sentences, any shareholders’ meeting will be deemed called and legally commenced, provided that the shareholders representing all of the voting shares are present, and provided that every present shareholder, whether or not such shareholder has paid the full price of such shareholder’s shares, agrees to hold the shareholders’ meeting and accepts the business to be discussed therein. Holders of Investment Shares have no right to request the Board to convene shareholders’ meetings.

| 125 |

Since we are a sociedad anónima abierta, notice of shareholders’ meetings must be given by publication of a notice, with the publication occurring at least 25 days before any shareholders’ meeting, in El Peruano and in a widely circulated newspaper in the city in which we are located. The notice requirement may be waived at the shareholders’ meeting by holders of 100% of the outstanding Common Shares. According to Article 25 of our By-laws and Article 257 of the Peruvian Companies Law, shareholders’ meetings called for the purpose of considering a capital increase or decrease, the issuance of obligations, a change in our By-laws, the sale in a single act of assets with an accounting value that exceeds 50% of our capital stock, a merger, division, reorganization, transformation or dissolution, are subject to a first, second and third quorum call, each of the second and third quorum to occur upon the failure of the preceding one. A quorum for the first call requires the presence of shareholders holding 50% of our total voting shares. For the second call, the presence of shareholders holding at least 25% of our total voting shares constitutes a quorum, and for the third call there is no quorum requirement. These decisions require the approval of the majority of the voting shares represented at the shareholders’ meeting. General Meetings convened to consider all other matters are subject to a first and second quorum call, the second quorum call to occur upon the failure of the first quorum.

In the case of shareholders’ meetings called for the purpose of considering the removal of members of the Board of Directors, at least 75% and 70% of the total number of Common Shares outstanding are required to be represented at the shareholders’ meeting on the first quorum call and second quorum call. Provided such quorum is attained, the affirmative vote of no less than two thirds of the total number of Common Shares outstanding is required to effect the removal of members of the Board of Directors. The special quorum and voting requirements described above cannot be modified at a shareholders’ meeting called for the purpose of considering the removal of members of the Board of Directors.

Under our By-laws, the following actions are to be taken at the annual obligatory shareholders’ meetings: approval of our statements of financial position, profit and loss statements and annual reports; the approval of management performance; the allocation of profits; the election of external auditors; the election of the members of the Board of Directors; and any other matters submitted by the Board of Directors. The following actions are to be taken at the same annual shareholders’ meetings if the quorum and majority requirements are met or at any other shareholders’ meeting: any amendment of our By-laws; any decision to increase or reduce capital; any decision to issue debt; initiating investigations or requesting auditor’s reports; liquidating, spinning-off, merging, consolidating, dissolving, or changing our business form or structure.

In accordance with Article 21 of the By-laws, only those holders of Common Shares whose names are inscribed in the Share Register not less than 10 days in advance of a meeting will be entitled to attend shareholders’ meetings and to exercise their rights.

Limitations on the Rights of Nonresident or Foreign Shareholders

There are no limitations in our By-laws or the Peruvian Companies Law on the rights of nonresident or foreign shareholders to own securities or exercise voting rights on our securities.

Change in Control

There are no provisions in our By-laws that would have the effect of delaying, deferring or preventing a change in control.

Disclosure of Share Holdings

There are no provisions in our By-laws governing the ownership threshold above which share ownership must be disclosed. However, according to Regulation No. 009-2006-EF.94.10 of the SMV, which became effective on May 3, 2006, as amended by Regulation No. 020-2006-EF.94.10 and Regulation No. 05-2009-EF-94.01.1 of the SMV, when an individual or financial group acquires, in one act or various successive acts, a significant percentage (more than 25%) of the voting shares of a company, as well as upon any person or group increasing its ownership above the 50 percent and 60% thresholds, a procedure known as Oferta Pública de Adquisición, or a “Takeover Bid,” must be followed. This has the effect of alerting other shareholders and the market that an individual or financial group has acquired a significant percentage of a company’s voting shares, and gives other shareholders the opportunity to sell their shares at the price offered by the purchaser. The purchaser is obliged to launch a Takeover Bid unless it is exempt pursuant to Regulation No. 009-2006-EF.94.10 of the SMV as amended. The purchase of ADRs is exempted from the Takeover Bid unless the holders: (i) exercises the voting rights of the Common Shares underlying the ADSs evidenced by such ADRs, or (ii) requests the delivery of such underlying Common Shares. In addition, the SMV and the Lima Stock Exchange must be notified of any transfer of more than 5 percent of our paid-in capital.

| 126 |

Changes in Capital

Our By-laws do not establish special conditions for increases or reductions of capital that are more stringent than is required by the Peruvian Companies Law. Furthermore, the Peruvian Companies Law forbids sociedades anónimas abiertas, such as us, from including in their By-laws stipulations limiting the transfer of their shares or restraining their trading in other ways. We cannot recognize a shareholders’ agreement that contemplates limitations, restrictions or preferential rights on the transfer of shares, even if such agreement is recorded in our Share Register (matrícula de acciones) or in CAVALI ICLV S.A.

C. Material Contracts

Not Applicable.

D. Exchange Controls

Since August 1990, there have been no exchange controls in Peru and all foreign exchange transactions are based on free market exchange rates. Before August 1990, the Peruvian foreign exchange market consisted of several alternative exchange rates. Additionally, during the 1990s, the Peruvian currency has experienced a significant number of large devaluations, and Peru has consequently adopted, and operated under, various exchange rate control practices and exchange rate determination policies, ranging from strict control over exchange rates to market determination of rates. Current Peruvian regulations on foreign investment allow the foreign holders of equity shares of Peruvian companies to receive and repatriate 100% of the cash dividends distributed by such companies. Such investors are allowed to purchase foreign exchange at free market currency rates through any member of the Peruvian banking system and transfer such foreign currency outside Peru without restriction.

E. Taxation

The following summarizes the material Peruvian and United States tax consequences under present law of the purchase, ownership and disposition of ADSs or Common Shares. The discussion is not a full description of all tax considerations that may be relevant to a decision to purchase ADSs or Common Shares. In particular, this discussion deals only with holders that hold ADSs or Common Shares as capital assets and that have the U.S. Dollar as their functional currency. The summary does not address the tax treatment of certain investors that may be subject to special tax rules, such as banks, securities dealers, insurance companies, tax-exempt entities, persons that will hold ADSs or Common Shares as a position in a “straddle” or “conversion transaction” for tax purposes and holders of 10% or more of our voting shares. This discussion does not address any U.S. state or local taxes, the U.S. federal alternative minimum tax or the U.S. Medicare tax on net investment income. There is no tax treaty currently in effect between Peru and the United States, except for a treaty to exchange tax information. The information to be exchanged is defined in such treaty as any data or declaration that may be relevant or essential to the administration and application of taxes. Accordingly, the discussions below of Peruvian and U.S. tax considerations are based on the domestic law of each of Peru and the United States which are subject to change and possibly with retroactive effect.

“U.S. Holder” means a beneficial owner of ADSs or Common Shares that is (i) a United States citizen or resident, (ii) a domestic corporation or partnership, (iii) a trust subject to the control of a U.S. fiduciary and the primary supervision of a U.S. court or (iv) estate the income of which is subject to United States federal income taxation regardless of its source.

Peruvian Tax Considerations

Cash Dividends and Other Distributions

Cash dividends paid with respect to Common Shares and amounts distributed with respect to ADSs are currently subject to a Peruvian withholding Income Tax, at a rate of 4.1% over the dividend paid (as long as such dividend is paid out from our accumulated net profits as of December 31, 2015), when the dividend is paid to shareholders that are: (i) individuals, whether resident or nonresident in Peru or (ii) nonresident entities. As a general rule, the distribution of additional Common Shares representing profits, distribution of shares which differ from the distribution of earnings or profits, as well as the distribution of preemptive rights with respect to Common Shares, which are carried out as part of a pro rata distribution to all shareholders, will not be subject to Peruvian Income Tax or withholding taxes. If the dividend distribution is paid out from our net profits after December 31, 2014, the Peruvian withholding Income Tax rate will increase to 6.8%, if the distribution is approved during 2015 and 2016, to 8% if it is approved during 2017 and 2018, and to 9.3% if it is approved in 2019 or later.

Law No. 30296, enacted on December 31, 2014, established certain amendments to the Peruvian Income Tax Law, (the “ITL”), effective from January 1, 2015. The most significant changes are the following: (i) a gradual increase of Peruvian withholding income tax over dividends paid from 4.1% to 6.8% in 2015 and 2016, to 8.0% in 2017 and 2018, and to 9.3% in 2019 and beyond. These tax rates will apply to profit distribution adopted or made available in cash or in kind, whichever occurs first, since January 1, 2015; and (ii) Peruvian withholding income tax of 4.1% will be applied to retained earnings or other items subject to generate taxable dividends, obtained up to December 31, 2014, and forming part of dividends distribution or any other profit distribution.

Capital Gains

Pursuant to Article 6 of the ITL, individuals and entities resident in Peru are subject to Peruvian Income Tax on their worldwide income while non-resident individuals or entities are subject to Peruvian Income Tax on their Peruvian source income only.

Furthermore, the ITL states that income deriving from the disposal of securities issued by Peruvian entities is considered Peruvian source income subject to the Income Tax.

With respect to this matter, Article 2 of the ITL, as amended by Legislative Decree 945, defines: (i) capital gains as any revenue deriving from the disposal of capital goods; and (ii) capital goods as those whose purpose is not to be traded in the regular course of a business. Moreover, Article 2 of the ITL states that income deriving from the disposal of shares and similar securities is considered a capital gain.

Accordingly, capital gains deriving from the disposal of securities issued by legal entities incorporated in Peru are considered Peruvian source income subject to Peruvian Income Tax.

Currently, regardless of whether or not the transferor is domiciled in Peru, the ITL establishes that taxable income resulting from the disposal of securities is determined by the difference between the sale price of the securities and its tax basis. However, before December 31, 2009, capital gains resulting from the disposal of ADSs or Common Shares issued by legal entities incorporated in Peru were exempt from Peruvian Income Tax if: (i) in the case of non-regular individuals (i.e., individuals who do not frequently trade securities), the transaction was carried out before December 31, 2009; and (ii) in the case of shareholders other than individuals, the transaction was carried out on the Lima Stock Exchange (floor session) before December 31, 2009.

Effective January 1, 2010, the exemption was repealed and, as such, capital gains resulting from the disposal of ADSs or Common Shares issued by legal entities incorporated in Peru became subject to Peruvian Income Tax, or the “Income Tax.” For non-resident entities or individuals, capital gains will be subject to an Income Tax rate of either 5% or 30%, depending where the transaction takes place. If the transaction is consummated within Peru, the Income Tax rate is 5%; if the transaction is consummated outside of Peru, capital gains are taxed at a rate of 30 percent.

The ITL Regulations have defined transactions consummated within Peru to mean that the securities at issue are transferred through the Lima Stock Exchange. In contrast, the transaction is considered to have been consummated abroad when (i) the securities at issue are not registered on the Lima Stock Exchange or (ii) registered securities are not transferred through the Lima Stock Exchange.

Before December 31, 2012, for nonresident individuals, the first five Tax Units (approximately US$6,800) of capital gains deriving from the transfer of securities were exempted from the Income Tax. Effective January 1, 2013, this exemption was repealed. If the transferor is a resident entity, capital gains deriving from the disposal of securities will be treated as any other taxable income subject to the 30% corporate Income Tax rate.

| 128 |

Furthermore, before December 31, 2012, if the transferor was a resident individual, the first five Tax Units (approximately US$6,800) of capital gains deriving from the transfer of securities were exempted from the Income Tax. Effective January 1, 2013, such exemption was repealed. Any capital gain earned by a resident individual is subject to the 5% annual Income Tax rate regardless of whether or not the transaction is carried out on the Lima Stock Exchange and regardless of how many transactions are carried out by such individual. In this case, the five percent Income Tax rate will be applicable over the annual net capital gain, which is calculated by deducting from the annual gross capital gain of the annual losses resulting from the disposal of shares during the same fiscal year.

Moreover, if the transferor, either a resident or nonresident individual or entity, acquired the ADSs or Common Shares that were exempt from the Income Tax before January 1, 2010, pursuant to a special provision of the ITL, the tax basis is the higher of: (i) the acquisition cost; (ii) the face or nominal value of the shares; or (iii) the stock market value at closing on December 31, 2009.

If the transferor, whether resident or nonresident in Peru, acquires the ADSs or Common Shares on or after January 1, 2010, the tax basis is: (i) for shares purchased by the transferor, the acquisition price paid for the shares; (ii) for shares received by the transferor as a result of a capital stock increase because of a capitalization of net profits, the face or nominal value of such shares; (iii) for other shares received free of any payment, the stock market value of such shares if listed on the Lima Stock Exchange or, if not, the face or nominal value of such shares; and (iv) for shares of the same type acquired at different opportunities and at different values, the tax basis will be the weighted average cost.

The aforementioned rules are also applicable to ADSs or Common Shares acquired before January 1, 2010 that were not exempt from the Income Tax as of December 31, 2009.

On December 31, 2010, Law No. 29645 was promulgated and took effect from January 1, 2011. This law states that in any transaction of Peruvian securities through the Lima Stock Exchange, CAVALI ICLV S.A. (the Peruvian clearing house) will act as withholding agent. As a result of this amendment, the nonresident will no longer have to self-assess and pay its Income Tax liability directly to the Peruvian Tax Administration.

Law No. 29645 has technically been in force since January 1, 2011. Implementing regulations were enacted in July 2011, and CAVALI ICLV S.A. began acting as a withholding agent on November 1, 2011. As a result, with regard to securities transferred through the Lima Stock Exchange by a nonresident transferor after November 1, 2011, such nonresident transferor is no longer obliged to self-assess and pay its Income Tax liability directly to Peruvian tax authorities within the first 12 working days following the month in which Peruvian source income was earned.

If the purchaser is resident in Peru and the sale is not performed through the Lima Stock Exchange, the purchaser will act as withholding agent, except in cases in which the transferor is a resident individual.

However, if the transferor is a resident entity, such transferor is solely responsible for its Peruvian Income Tax on capital gains resulting from the disposal of ADSs or Common Shares, regardless of whether such securities are listed on the Lima Stock Exchange or elsewhere.

Other Considerations

No Peruvian estate or gift taxes are imposed on the gratuitous transfer of ADSs or Common Shares. No stamp, transfer or similar tax applies to any transfer of Common Shares, except for commissions payable by seller and buyer to the Lima Stock Exchange (0.15% of value sold), fees payable to the SMV (0.05% of value sold), brokers’ fees (about 0.05% to 1% of value sold) and Value Added Tax (at the rate of 18%) on commissions and fees. Any investor who sells its Common Shares on the Lima Stock Exchange will incur these fees and taxes upon purchase and sale of the Common Shares.

United States Federal Income Tax Considerations

Assuming the obligations contemplated by the Amended and Restated Deposit Agreement are being performed in accordance with its terms, holders of ADSs (or ADRs evidencing ADSs) generally will be treated for United States federal income tax purposes as the owners of the Common Shares represented by those ADSs.

| 129 |

Cash Dividends and Other Distributions

Cash dividends paid with respect to Common Shares or Common Shares represented by ADSs generally are includible in the gross income of a U.S. Holder as ordinary income. Dividends generally are treated as foreign source income. Dividends paid to a U.S. Holder that is a corporation are not eligible for the dividends received deduction available to corporations. Under current law, a maximum 20% U.S. tax rate is imposed on the dividend income of an individual U.S. Holder with respect to dividends paid by a domestic corporation or “qualified foreign corporation” if certain holding period requirements are met. A qualified foreign corporation generally includes a foreign corporation if (i) its shares are readily tradable on an established securities market in the U.S. or (ii) it is eligible for benefits under a comprehensive U.S. income tax treaty. Clause (i) will apply with respect to ADSs if such ADSs are readily tradable on an established securities market in the U.S. The ADSs are traded on the New York Stock Exchange. As a result, we believe that we should be treated as a qualified foreign corporation and, therefore, dividends paid to an individual U.S. Holder with respect to ADSs for which the minimum holding period requirement is met should be taxed at a maximum rate of 20%. Dividends paid in Soles are includible in a United States dollar amount based on the exchange rate in effect on the date of receipt (which, in the case of ADSs, will be the date of receipt by the Depositary) whether or not the payment is converted into U.S. Dollars at that time. Any gain or loss recognized upon a subsequent sale or conversion of the Soles for a different amount of U.S. Dollars will be United States source ordinary income or loss. Distributions to U.S. Holders of additional Common Shares or preemptive rights with respect to Common Shares that are made as part of a pro rata distribution to all of our shareholders generally will not be subject to United States federal income tax but in other circumstances may constitute a taxable dividend.

A U.S. Holder will be entitled to a foreign tax credit for Peruvian taxes imposed by withholding or otherwise, subject to generally applicable limitations and restrictions. In the case of U.S. individuals for whom the reduced rate of tax on dividends applies, such limitations and restrictions will appropriately take into account the rate differential under rules similar to section 904(b)(2)(B) of the Internal Revenue Code. The rules governing foreign tax credits are complex and U.S. Holders should consult their tax advisors regarding their application to the particular circumstances of such holder.

A non-U.S. Holder generally is not subject to United States federal income or withholding tax on dividends paid with respect to Common Shares or Common Shares represented by ADSs, unless such income is effectively connected with the conduct by the non-U.S. Holder of a trade or business within the United States.

Capital Gains

U.S. Holders will recognize capital gain or loss on the sale or other disposition of ADSs or Common Shares (or preemptive rights with respect to such shares) held by the U.S. Holder or by the Depositary. U.S. Holders will not recognize gain or loss on deposits or withdrawals of Common Shares in exchange for ADSs or on the exercise of preemptive rights. Any gain recognized by a U.S. Holder generally will be treated as United States source income. Consequently, in the case of a disposition of Common Shares or ADSs in a transaction subject to Peruvian tax, the U.S. Holder may not be able to claim the foreign tax credit for any Peruvian tax imposed on the gain unless it has sufficient foreign source income from other sources against which it can apply the credit. Generally, gain or loss will be a long-term capital gain or loss if the U.S. Holder’s holding period for such Common Shares or ADSs exceeds one year. Long-term capital gain for an individual U.S. Holder is generally subject to a reduced rate of tax.

A non-U.S. Holder of ADSs or Common Shares will not be subject to United States income or withholding tax on gain from the sale or other disposition of ADSs or Common Shares unless (i) such gain is effectively connected with the conduct of a trade or business within the United States or (ii) the non-U.S. Holder is an individual who is present in the United States for at least 183 days during the taxable year of the disposition and certain other conditions are met.

Passive Foreign Investment Company

We believe that we are not and will not become a passive foreign investment company for United States federal income tax purposes. A foreign corporation is a passive foreign investment company (“PFIC”) in any taxable year in which, after taking into account the income and assets of certain subsidiaries pursuant to the applicable look-through rules, either (i) at least 75% of its gross income is passive income or (ii) at least 50% of the average value of its assets is attributable to assets that produce passive income or are held for the production of passive income.

| 130 |

If we were a PFIC in any year during which a U.S. Holder owned ADSs or Common Shares, we would not be treated as a “qualified foreign corporation” for purposes of qualifying dividends paid to a U.S. Holder for the preferential 20% maximum U.S. tax rate noted above and the U.S. Holder would be subject to additional taxes on any excess distributions received from us and any gain realized from the sale or other disposition of ADSs or Common Shares (regardless of whether we continued to be a PFIC). A U.S. Holder has an excess distribution to the extent that distributions on ADSs or Common Shares during a taxable year exceed 125 percent of the average amount received during the three preceding taxable years (or, if shorter, the U.S. Holder’s holding period for the ADSs or Common Shares). To compute the tax on an excess distribution or any gain, (i) the excess distribution or the gain is allocated ratably over the U.S. Holder’s holding period for the ADSs or Common Shares, (ii) the amount allocated to the current taxable year is taxed as ordinary income and (iii) the amount allocated to other taxable years is taxed at the highest applicable marginal rate in effect for each year and an interest charge is imposed to recover the deemed benefit from the deferred payment of the tax attributable to each year.

If we were a PFIC, U.S. Holders of interests in a holder of ADSs or Common Shares may be treated as indirect holders of their proportionate share of the ADSs or Common Shares and may be taxed on their proportionate share of any excess distribution or gain attributable to the ADSs or Common Shares. An indirect holder also must treat an appropriate portion of its gain on the sale or disposition of its interest in the actual holder as gain on the sale of the ADSs or Common Shares.

Information Reporting and Backup Withholding

Dividends in respect of the ADSs or Common Shares and the proceeds from the sale, exchange, or redemption of the ADSs or Common Shares may be reported to the United States Internal Revenue Service and a backup withholding tax may apply to such amounts unless the holder (i) is a domestic corporation (which may be required to establish its exemption by carrying its status on U.S. Internal Revenue Service Form W-9), (ii) in the case of a U.S. Holder other than a corporation, provides an accurate taxpayer identification number in the manner required by applicable law, (iii) in the case of a non-U.S. Holder, provides a properly executed U.S. Internal Revenue Service Form W-8BEN, or other successor Form, or (iv) otherwise establishes a basis for exemption. The amount of any backup withholding from a payment to a U.S. Holder generally will be allowed as a credit against the U.S. Holder’s United States federal income tax liability.

I. Subsidiary Information

Not applicable.

| ITEM 11. | Quantitative and Qualitative Disclosures About Market Risk

The following discussion contains forward-looking statements that are subject to risks and uncertainties, many of which are outside of our control. Our primary market risks are related to fluctuations in the prices of gold, silver, zinc and lead. To a lesser extent, we are subject to market risk related to fluctuations in US$/ Sol exchange rates and to market risk related to interest rate fluctuation on our cash balances.

Commodity Contracts

Gold, silver, lead and copper hedging and sensitivity to market price

Our revenues and earnings are to a great extent influenced by world market prices for gold, copper, silver, zinc and lead that fluctuate widely and over which we have no control. We and our wholly-owned subsidiaries are completely unhedged as to the price at which our gold and silver will be sold. See “Item 3. Key Information—D. Risk Factors—Factors Relating to the Company—Our financial performance is highly dependent on the prices of gold, silver, copper and other metals.”

As of March 31, 2016, we had no fixed price commitments for the sale of our metals. As of March 31, 2016, we had no silver derivative contracts or gold convertible put option contracts in place.

Yanacocha and Cerro Verde have informed us that they have generally not engaged in, and are currently not engaged in, gold or copper price hedging activities, such as forward sales or option contracts, to minimize their exposure to fluctuations in the prices of gold or copper.

Normal Sales

We had no normal sales contracts with fixed or capped prices outstanding as of March 31, 2016.

Foreign currency risk

We buy and sell our products and obtain capital facilities and investment in U.S. Dollars. The assets and liabilities in different currencies from the U.S. Dollar (Soles) are not significant. We estimate that the future exchange rate fluctuations of Peruvian currency versus the U.S. Dollar will not significantly affect the results of our future operations.

Interest Rate Sensitivity

We reduce our exposure to the risks due to variations in interest rates by engaging in financial obligations and capital leasing with fixed interest rates. See Note 31 to the Financial Statements. Consequently, we do not use derivative instruments to manage this risk and we do not expect to incur significant losses based on interest risks.

D. American Depositary Shares

The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may collect its annual fee for depositary services by deductions from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The Depositary may generally refuse to provide fee-attracting services until its fees for those services are paid. The following table summarizes the fees and expenses payable by holders of ADSs:

Persons depositing or withdrawing shares must pay: |  | For:
US$5.00 (or less) per 100 ADSs (or portion of 100 ADSs) |  | • | Issuance of ADSs, including issuances resulting from a distribution of shares or rights or other property
|  | • | Cancellation of ADSs for the purpose of withdrawal, including if the deposit agreement terminates
A fee equivalent to the fee that would be payable if securities distributed to you had been shares and the shares had been deposited for issuance of ADSs |  | • | Distribution of securities distributed to holders of deposited securities which are distributed by the depositary to ADS registered holders
Registration or transfer fees |  | • | Transfer and registration of shares on our share register to or from the name of the Depositary or its agent when you deposit or withdraw shares
Expenses of the Depositary |  | • | Cable, telex and facsimile transmissions (when expressly provided in the deposit agreement)
|  | • | Converting foreign currency to U.S. Dollars
Taxes and other governmental charges the Depositary or the custodian have to pay on any ADS or share underlying an ADS, for example, stock transfer taxes, stamp duty or withholding taxes |  | • | As necessary
Any charges incurred by the Depositary or its agents for servicing the deposited securities |  | • | As necessary

Fees Incurred in Past Annual Period

From January 1, 2015 to April 30, 2016, we received no fees from the Depositary related to our ADR facility, including continuing annual stock exchange listing fees, standard out-of-pocket maintenance costs for the ADRs (consisting of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend checks, electronic filing of U.S. federal tax information, mailing required tax forms, stationery, postage, facsimile, and telephone calls), any applicable performance indicators relating to the ADR facility, underwriting fees and legal fees.

Fees to be Paid in the Future

The Depositary has agreed to reimburse us for expenses we incur that are related to establishment and maintenance expenses of the ADS program. The Depositary has agreed to reimburse us for our continuing annual stock exchange listing fees. The Depositary has also agreed to pay the standard out-of-pocket maintenance costs for the ADRs, which consist of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend checks, electronic filing of U.S. federal tax information, mailing required tax forms, stationery, postage, facsimile, and telephone calls. It has also agreed to reimburse us annually for certain investor relationship programs or special investor relations promotional activities. In certain instances, the Depositary has agreed to provide additional payments to us based on any applicable performance indicators relating to the ADR facility. There are limits on the amount of expenses for which the Depositary will reimburse us, but the amount of reimbursement available to us is not necessarily tied to the amount of fees the Depositary collects from investors.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2015, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon and as of the date of our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported as and when required.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Our management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2015. In making its assessment, management has utilized the criteria set forth by the Committee of Sponsoring Organizations (the “COSO”) of the Treadway Commission in Internal Control—Integrated Framework (1992). Our management concluded that based on its assessment, our internal control over financial reporting was effective as of December 31, 2015.

Our independent registered public accounting firm, Paredes, Zaldívar, Burga & Asociados S. Civil de R.L., has issued an attestation report on our internal control over financial reporting, which is included below.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Compañía de Minas Buenaventura S.A.A.

We have audited Compañía de Minas Buenaventura S.A.A.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission - the COSO criteria. Compañía de Minas Buenaventura S.A.A.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

| 135 |

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Compañía de Minas Buenaventura S.A.A. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statements of financial position of Compañía de Minas Buenaventura S.A.A. and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of profit or loss, other comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2015 of Compañía de Minas Buenaventura S.A.A. and subsidiaries and our report dated February 25, 2016, expressed an unqualified opinion thereon.

Paredes, Zaldívar, Burga & Asociados S. Civil de R.L. has served as our independent public accountant for each of the fiscal years in the two-year period ended December 31, 2014 and 2015, for which audited financial statements appear in this annual report on Form 20-F.

The following table presents the aggregate fees for professional services and other services rendered by Paredes, Zaldívar, Burga & Asociados S. Civil de R.L. for 2014 and 2015.

|  | Year ended December 31, |
|  | 2014 |  |  | 2015 |

Civil de R.L. in connection with the audit of our annual financial statements, the review of our quarterly financial statements and statutory and regulatory audits. In addition, the amounts in the above table includes fees that were incurred in connection with the audit of internal control over financial reporting in 2014 and 2015.

Audit Committee Pre-approval Policies and Procedures

Our Audit Committee is responsible for the oversight of the independent auditor. The Audit Committee has adopted a policy regarding pre-approval of audit services provided by our independent auditors, or the “Policy.” In accordance with the Policy, the Audit Committee must pre-approve the provision of services by our independent auditor for all audit and non-audit services before commencement of the specified service. The requests for pre-approval are submitted to the Audit Committee by the Chief Financial Officer and following approval by audit committee members an engagement letter is executed. The Audit Committee approved all audit and tax fees in 2014 and 2015.

Not applicable.

| ITEM 16E. | Purchases of Equity Securities by the Issuer and Affiliated Purchasers

For the year ended December 31, 2015, neither we nor any person acting on our behalf made any purchase of our Common Shares.

| ITEM 16F. | Change in Registrant’s Certifying Accountant

None.

| ITEM 16G. | Corporate Governance

There are significant differences in the corporate governance practices followed by us as compared to those followed by United States domestic companies under the NYSE, listing standards. The NYSE listing standards provide that the board of directors of a United States domestic listed company must consist of a majority of independent directors and that certain committees must consist solely of independent directors. Under Peruvian corporate governance practices, a Peruvian company is not required to have a majority of the members of the board of directors be independent.

| 137 |

The listing standards for the NYSE also require that United States domestic companies have an audit committee, a nominating/corporate governance committee and a compensation committee. Each of these committees must consist solely of independent directors and must have a written charter that addresses certain matters specified in the listing standards. Peruvian corporate governance practices permit the Board of Directors of a Peruvian company to form special governance bodies in accordance with the needs of such company and do not require that these special governance bodies be composed partially or entirely of independent directors. We maintain three committees, which include the Audit Committee, the Compensation Committee and the Nominating/Corporate Governance Committee. Our Board of Directors has determined that our Audit Committee is composed entirely of independent directors, as defined in the NYSE’s Listed Company Manual.

The NYSE’s listing standards also require United States domestic companies to adopt and disclose corporate governance guidelines. In July 2002, the SMV and a committee comprised of regulatory agencies and associations prepared and published a list of suggested corporate governance guidelines called “Principles of Good Governance for Peruvian Companies.” These principles are disclosed on the SMV’s website at http://www.smv.gob.pe. Our code of business conduct and ethics establishes our principles of good corporate governance and, as indicated in “Item 16B. Code of Ethics,” is posted on our website.

(a Peruvian public corporation) and subsidiaries (together the “Group”), which comprise the consolidated statements of financial position as of December 31, 2015 and 2014, and the related consolidated statements of profit or loss, statements of other comprehensive income, statements of changes in equity and statements of cash flows for the years ended December 31, 2015, 2014 and 2013. These consolidated financial statements are the responsibility of the Group's Management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We did not audit the financial statements of Minera Yanacocha S.R.L (an associate in which the Company has a 43.65% interest through its subsidiary, Compañía Minera Condesa S.A.) as of December 31, 2014 and for the years ended December 31, 2014 and 2013. In the consolidated statements of financial position, the Group’s investment in Minera Yanacocha S.R.L., is stated at US$1,186 million as of December 31, 2014, and the Group’s equity in the results of Minera Yanacocha S.R.L. is stated at a loss of US$175 million and US$251 million for the years ended December 31, 2014 and 2013, respectively. Those statements were audited by other auditors whose reports were furnished to us, and our opinion, insofar as it relates to the amounts included for Minera Yanacocha S.R.L., is based solely on the reports of the other auditors.

Scope

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by Management, as well as evaluating the overall financial statement presentation. We believe that our audits and the report of other auditors provide a reasonable basis for our opinion.

Opinion

In our opinion, based on our audits and the report of other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Compañía de Minas Buenaventura S.A.A. and Subsidiaries as of December 31, 2015 and 2014, and their results of operations and their cash flows for each of the years ended on December 31, 2015, 2014 and 2013, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB).

Additional information

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Compañía de Minas Buenaventura S.A.A.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission “(2013 framework)” and our report dated February 25, 2016 expressed an unqualified opinion thereon.

| - | Exposure, or rights, to variable returns from its involvement with the investee;

| - | The ability to use its power over the investee to affect its returns.

Generally, there is a presumption that a majority of voting rights result in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

| - | The contractual arrangement with the other vote holders of the investee;

| - | Rights arising from other contractual arrangements;

| - | The Group’s voting rights and potential voting rights or a combination of rights.

The Group re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Group gains control until the date the Group ceases to control the subsidiary.

Profit or loss and each component of other comprehensive income are attributed to the equity holders of the Parent of the Group and to the non-controlling interests, even if this results in the non-controlling interests having a deficit balance. When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with the Group’s accounting policies.

All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation.

A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction.

| 2.3. | Changes in accounting policies and disclosures -

Certain standards and amendments applied for the first time in 2015; however, they did not have material impact on the annual consolidated financial statements of the Group and therefore, have not been disclosed. The Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective.

| 2.4. | Summary of significant accounting policies –

| (a) | Foreign currencies -

The consolidated financial statements are presented in U.S. dollars, which is also the Group’s functional currency.

For each entity, the Group determines the functional currency and the items included in the financial statements of each entity are measured using that functional currency.

Transactions and balances

Transactions in foreign currency (a currency other than the functional currency) are initially recorded by the Group at the exchange rates prevailing at the dates of the transactions, published by the Superintendence of Banking and Insurance and Pension Fund Administrators (AFP for its acronym in Spanish).

Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rates of exchange at the reporting date. Gains or losses from exchange differences arising from the settlement or translation of monetary assets and liabilities are recognized in the consolidated statements of profit or loss.

Non-monetary assets and liabilities recognized in terms of historical cost are translated using the exchange rates prevailing at the dates of the initial transactions.

| (b) | Financial instruments -

Initial recognition and measurement

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

| (i) | Financial assets -

Initial recognition and measurement

Financial assets are classified, at initial recognition, as financial assets at fair value through profit or loss, loans and receivables, held-to-maturity investments, available-for-sale financial assets, or derivatives designated as hedging instruments in an effective hedge, as appropriate. All financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit or loss, transaction costs that are attributable to the acquisition of the financial asset.

| F-15 |

Notes to the consolidated financial statements (continued)

Subsequent measurement -

For purposes of subsequent measurement, financial assets are classified in four categories:

| - | Financial assets at fair value through profit or loss;

| - | Loans and receivables;

| - | Held-to-maturity investments;

| - | Available-for-sale financial investments.

Financial assets at fair value through profit or loss -

Financial assets at fair value through profit or loss include financial assets held for trading and financial assets designated upon initial recognition at fair value through profit or loss. Financial assets are classified as held for trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments as defined by IAS 39.

Financial assets at fair value through profit or loss are carried in the consolidated statements of financial position at fair value with net changes in fair value presented as finance costs (negative changes) or finance revenue (positive changes) in the consolidated statements of profit or loss.

Derivatives embedded in host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value though profit or loss. These embedded derivatives are measured at fair value, with changes in fair value recognized in profit or loss.

Loans and receivables -

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate method, less impairment. The losses arising from impairment are recognized in the consolidated statements of profit or loss.

This category generally applies to trade and other receivables, net.

Held-to-maturity investments -

Non-derivative financial assets with fixed or determinable payments and fixed maturities are classified as held to maturity when the Group has the positive intention and ability to hold them to maturity. The Group did not have any held-to-maturity investment as of December 31, 2015 and 2014.

Available-for-sale financial assets -

The available-for-sale financial assets include equity investments and debt securities. Equity investments classified as available for sale are those that are neither classified as held for trading nor designated at fair value through profit or loss. Debt securities in this category are those that are intended to be held for an indefinite period of time and may be sold in response to needs for liquidity or in response to changes in the market conditions. The Group did not have these financial assets as of December 31, 2015 and 2014.

| F-16 |

Notes to the consolidated financial statements (continued)

Derecognition -

A financial asset (or, where applicable a part of a financial asset or part of a group of similar financial assets) is primarily derecognized when:

| - | The rights to receive cash flows from the asset have expired;

| - | The Group has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a pass-through arrangement; and either (a) the Group has transferred substantially all the risks and rewards of the asset or, (b) the Group has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Group has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent, it has retained the risk and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Group continues to recognize the transferred asset to the extent of the Group´s continuing involvement. In that case, the Group also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained.

Impairment of financial assets -

The Group assesses, at each reporting date, whether there is objective evidence that a financial asset or group of financial assets is impaired. An impairment exists if one or more events that has occurred since the initial recognition of the asset (an incurred "loss event"), has an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated.

Evidence of impairment may include indications that the debtors or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization and observable data indicating that there is a measurable decrease in the estimated future cash flows, such as changes in economic conditions that correlate with defaults.

For financial assets carried at amortized cost, the Group first assesses whether impairment exists for financial assets that are individually significant, or collectively for financial assets that are individually insignificant.

The amount of any impairment loss in the impairment identified is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows. The present value of the estimated future cash flows is discount at the financial asset’s original effective interest rate.

The carrying amount of the asset is reduced through the use of an allowance account and the loss is recognized in the consolidated statements of profit or loss. Interest income (recorded as revenue in the statements of profit or loss) continues to be accrued on the reduced carrying amount and is accrued using the interest rate used to discount the future cash flows for the purpose of measuring the impairment loss. Loans together with the associated allowance are written off when there is no realistic prospect of a future recovery and all collateral has been realized or has been transferred to the Group. If, in a subsequent year, the amount of the estimated impairment loss increases or decreases because of an event occurring after the impairment was recognized, the previously recognized impairment loss is increased or reduced by adjusting the allowance account. If a write-off is later recovered, the recovery is credited to finance costs in the consolidated statements of profit or loss.

| F-17 |

Notes to the consolidated financial statements (continued)

| (ii) | Financial liabilities –

Initial recognition and measurement -

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, accounts payable, financial obligations, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of interest-bearing loans and borrowings and payables, net of directly attributable transaction costs.

The Group’s financial liabilities include trade and other payables, financial obligations, derivatives financial instruments and embedded derivatives.

| F-18 |

Notes to the consolidated financial statements (continued)

Subsequent measurement -

The measurement of financial liabilities depends on their classification, as described below:

Financial liabilities at fair value through profit or loss -

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss.

Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Group that are not designated as hedging instruments in hedge relationships as defined by IAS 39. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the consolidated statements of profit or loss.

Except for the embedded derivative for concentrate sales, the Group has not designated any financial liability in this category.

Loans and borrowings -

After initial recognition, interest-bearing loans and borrowing are subsequently measured at amortized cost using the effective interest rate method. Gains and losses are recognized in the consolidated statements of profit and cost when the liabilities are derecognized as well as through the amortization process.

Amortized cost is calculated taking into account any discount or premium on acquisition and fees or costs that are an integral part of the effective interest rate. Amortization under the effective interest rate method is included as financial costs in the consolidated statements of profit or loss.

Derecognition -

A financial liability is derecognized when the obligation under the liability is discharged or cancelled, or expires.

When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the consolidated statements of profit or loss.

| (iii) | Offsetting of financial instruments -

Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statements of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

| F-19 |

Notes to the consolidated financial statements (continued)

| (c) | Cash and cash equivalents -

Cash and cash equivalents in the consolidated statements of financial position comprise cash at banks and on hand.

For the purpose of the consolidated statements of cash flows, cash and cash equivalents consist of cash and short term deposits with a maturity of three months or less, which are subject to an insignificant risk of changes in value.

| (d) | Inventories -

Materials and supplies are valued at the lower of cost or net realizable value.

Cost is determined using the average method. In the case of finished goods and work in progress, cost includes the cost of materials and direct labor and a portion of indirect manufacturing expenses, excluding borrowing costs.

The current portion of the inventories is determined based on the expect amounts to be processed within the next twelve months. Inventories not expected to be processed within the next twelve months are classified as long-term.

Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs to make the sale.

Provision (reversal) for losses on the net realizable value are calculated based on a specific analysis conducted annually by the Management and is charged to income in the period in which it determines the need for the provision (reversal).

| (e) | Business combinations and goodwill -

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred measured at acquisition date fair value and the amount of any non-controlling interest in the acquiree. For each business combination, the Group elects whether to measure the non-controlling interests in the acquiree at fair value or at the proportionate share of the acquiree’s identifiable net assets. Acquisition-related costs are expensed as incurred and included in administrative expenses.

| F-20 |

Notes to the consolidated financial statements (continued)

When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree.

If the business combination is achieved in stages, any previously held equity interest is re-measured at its acquisition date fair value and any resulting gain or loss is recognized in profit or loss.

Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IAS 39 Financial Instruments: Classification and Measurement, is measured at fair value, with changes in fair value recognized in either profit or loss or as a change to other comprehensive income. If the contingent consideration is not within the scope of IAS 39, it is measured in accordance with the appropriate IFRS. Contingent consideration that is classified as equity is not re-measured and subsequent settlement is accounted for within equity.

Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling interests, and any previous interests held, over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, the Group re-assesses whether it has correctly identified again all of the assets acquired and all of the liabilities assumed and reviews the procedures used to measure the amounts to be recognized at the acquisition date. If the re-assessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain is recognized in profit of loss.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, this difference is allocate to each of the Group’s cash-generating units that are expected to benefit from the combination, irrespective of whether other assets or liabilities, of the acquiree, are assigned to those units.

Where goodwill has been allocated to a cash-generating unit and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed of in these circumstances is measured based on the relative values of the disposed operation and the portion of the cash-generating unit retained.

| F-21 |

Notes to the consolidated financial statements (continued)

| (f) | Investments in associates -

An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but is not control over those policies. The Group's investments in associates are accounted for using the equity method. Under this method, the investment in an associate is initially recognized at cost.

The carrying amount of the investment is adjusted to recognize changes in the Group's share of net assets of the associate since the acquisition date. Goodwill relating to the associate is included in the carrying amount of the investment and is not tested for impairment individually.

The consolidated statement of profit or loss reflects the Group’s share of the results of operations of the associate.

Any change in other comprehensive income of those investees is presented as part of the Group’s other comprehensive income. In addition, when there has been a change recognized directly in the equity of the associate, the Group recognizes its share of any changes, when applicable, in the consolidated statements of changes in shareholders’ equity. Unrealized gains and losses resulting from transactions between the Group and the associate are eliminated to the extent of the interest in the associate.

The aggregate of the Group´s share of profit or loss of an associate is shown on the face of the consolidated statements of profit or loss outside operating profit and represents profit or loss after tax and non-controlling interests in the subsidiaries of the associates.

The financial statements of the associate are prepared for the same reporting period as the Group. When necessary, adjustments are made to bring the accounting policies in line with those of the Group.

After the application of the equity method, the Group determines whether it is necessary to recognize an impairment loss of its investment in associates. At each reporting date, the Group determines whether there is objective evidence that the investment in the associate is impaired. If there is such evidence, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value, and then recognizes the loss in the consolidated statements of profit or loss.

Upon loss of significant influence over the associate, the Group measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate upon loss of significant influence and the fair value of the retained investment and proceeds from disposal is recognized in consolidated statements of profit or loss.

| F-22 |

Notes to the consolidated financial statements (continued)

| (g) | Prepaid expenses -

Non-monetary assets which represent an entity’s right to receive goods or services are presented as prepaid expenses. The asset is subsequently derecognized when the goods are received and the services are rendered.

| (h) | Property, plant and equipment -

Property, plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any.

The initial cost of an asset comprises its purchase price or construction cost, any costs directly attributable to bringing the asset into operation, the initial estimate of the obligation for mine closing and for qualifying assets, borrowing costs. The capitalized value of a finance lease is also included in this caption.

When significant parts of property, plant and equipment are required to be replaced at intervals, the Group depreciates them separately based on their specific useful lives. Also, when a major inspection is performed, its cost is recognized in the carrying amount of plant and equipment as a replacement if the recognition criteria are satisfied. All other maintenance and repair costs are recognized in the consolidated statement of profit or loss as incurred.

Depreciation -

Unit-of-production method:

In mining units with a long-term useful life, depreciation of assets directly related to the operation of the mine, is calculated using the units-of-production method, which is based on economically recoverable reserves of the mining unit. Other assets related to these mining units are depreciated using the straight-line method with the lives detailed in the next paragraph.

Straight-line method:

Depreciation of assets in mining units with short useful lives or used for administrative purposes, is calculated using the straight-line method of accounting. The useful lives are the following:

| Years
Buildings, construction and other | Between 6 and 20
Machinery and equipment | Between 5 and 10
Transportation units | 5
Furniture and fixtures | 10
Computer equipment | 4

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end, and adjusted prospectively, if appropriate.

Disposal of assets -

An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the consolidated statements of profit or loss when the asset is derecognized.

| F-23 |

Notes to the consolidated financial statements (continued)

| (i) | Leases -

The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains, a lease if fulfillment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement.

Group as a lessee -

A lease is classified at the inception date as a finance lease or an operating lease. A lease that transfers substantially all the risk and rewards incidental to ownership to the Group is classified as a finance lease. Finance leases are capitalized at the commencement of the lease at the fair value of the leased property or, if lower, at the present value of the minimum lease payments. Lease payments are apportioned between finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability. Finance charges are recognized in finance costs in the consolidated statements of profit or loss.

A leased asset is depreciated over the useful life of the asset. However, if there is no reasonable certainty that the Group will obtain ownership by the end of the lease term, the asset is depreciated over the shorter of the estimated useful life of the asset and the lease term.

Operating lease payments are recognized as operating expenses in the statements of profit or loss on a straight-line basis over the lease term.

Group as a lessor -

Leases in which the Group does not transfer substantially all the risk and rewards of ownership of an asset are classified as operating leases.

Initial direct cost incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same basis as rental income. Contingent rents are recognized as revenue in the period in which they are earned.

| F-24 |

Notes to the consolidated financial statements (continued)

| (j) | Mining concessions -

Mining concessions represent ownership of the right of exploration and exploitation to the Group on mining properties contains ore reserves acquired. Mining concessions are stated at cost and are amortized on units of production method, using as the basis of proven and probable reserves. If the Group leaves these concessions, the costs associated are written off in the consolidated statements of profit or loss.

Cost includes the fair value attributable to mineral reserves and the portion of mineral resources considered to be probable of economic extraction at the time of an acquisition.

At end of each year, the Group evaluates if there is any indicator. If any impairment indicator exists, the Group estimates the asset’s recoverable amount.

Mining concessions are presented in the caption of mining concessions, development costs, property, plant and equipment, net.

| (k) | Exploration and mine development costs –

Exploration expenditure -

Exploration costs are expensed as incurred. These costs primarily include materials and fuels used, surveying costs, drilling costs and payments made to the contractors.

Exploration and evaluation activity includes:

| - | Researching and analyzing historical exploration data;

| - | Gathering exploration data through geophysical studies;

| - | Exploratory drilling and sampling;

| - | Determining and examining the volume and grade of the resource;

| - | Surveying transportation and infrastructure requirements;

| - | Conducting market and finance studies.

Development costs -

When the Group’s Management approves the feasibility of the conceptual study of a project, the costs incurred to develop such property, including additional costs to delineate the ore body and remove impurities it contains, are capitalized as development costs under the caption mining concessions, development costs and property, plant and equipment, net. These costs are amortized when production begins, on the units-of-production basis over the proven and probable reserves.

The development costs include:

| - | Metallurgical and engineering studies;

| - | Drilling and other costs necessary to delineate ore body;

| - | Removal of the initial clearing related to an ore body.

Development costs necessary to maintain production are expensed as incurred.

| F-25 |

Notes to the consolidated financial statements (continued)

| (l) | Stripping (waste removal) costs -

As part of its mining operations, the Group incurs waste removal costs (stripping costs) during the development and production phases of its mining operations. Stripping costs incurred in the development phase of a mine, before the production phase commences (development stripping), are capitalized as part of the cost of constructing the mine and subsequently amortized over its useful life using units of production method. The capitalization of development stripping costs ceases when the mine starts production.

Stripping costs incurred during the production phase (production stripping costs) are generally considered to create two benefits, being either the production of inventory or improved access to the ore to be mined in the future. Where the benefits are realized in the form of inventory produced in the period, the production stripping costs are accounted for as part of the cost of producing those inventories. Where the benefits are realized in the form of improved access to ore to be mined in the future, the costs are recognized as a non-current asset, referred to as a stripping activity asset, if the following criteria are met:

| - | Future economic benefits are probable;

| - | The component of the ore body for which access will be improved can be accurately identified;

| - | The costs associated with the improved access can be reliably measured.

To identify components of deposit, the Group works closely with the operating personnel to analyze the mine plans. Mostly, an ore body can have several components. The mine plans, and therefore, the identification of components, will vary among mines for a number of reasons.

The stripping activity asset is initially measured at cost, which surges from an accumulation of costs directly incurred during the stripping activity. The production stripping cost is presented within mining concessions, development costs, property, plant and equipment, net in the consolidated statements of financial position.

The production stripping cost is subsequently depreciated using the units of production method over the expected useful life of the component identified of the ore body that has been made more accessible by the activity. This cost is stated at cost less accumulated depreciation and accumulated impairment losses, if any.

| (m) | Investment properties –

Investment properties are measured at cost, net of accumulated depreciation and impairment loss, if any.

Depreciation of the investment properties is determined using the straight-line method with useful life of 20 years.

Investment properties are derecognized either when they have been disposed of or when they are permanently withdrawn from use and no future economic benefit is expected from their disposal. The difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period of derecognition.

Transfers are made to (or from) investment property only when there is a change in use.

For a transfer from investment property to an item of property, plant and equipment, the deemed cost for subsequent accounting is the fair value at the date of change in use. If an item of property, plant and equipment becomes an investment property, the Group accounts for such property in accordance with the policy stated under property, plant and equipment up to the date of change in use.

| F-26 |

Notes to the consolidated financial statements (continued)

| (n) | Impairment of non-financial assets -

The Group assesses, at each reporting date, whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for an asset is required, the Group estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s or cash-generating unit (CGU) fair value less costs of disposal and its value in use. Recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In determining fair value less cost of disposal, recent market transactions are taken into account. If no such transactions can be identified, an appropriate valuation model is used.

Impairment losses of continuing operations, including impairment of inventories, are recognized in the consolidated statements of profit or loss in expense categories consistent with the function of the impaired asset.

For assets in general, an assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses may no longer exist or have decreased. If such indication exists, the Group estimates the asset’s or CGU’s recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset or CGU’s recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the consolidated statements of profit or loss.

| (o) | Share-based payments -

Senior executives of the Group receive remuneration in the form of share appreciation rights, which can only be settled in cash. For these transactions, the amount of the liability is estimated at each reporting date until settlement.

The cost of share-based payments program is measured initially at fair value at the grant date using a binomial model. This fair value is expensed over the period until the vesting date with recognition of a corresponding liability. The liability is re-measured to fair value at each reporting date up to, and including the settlement date, with changes in fair value recognized in its consolidated statements of profit or loss.

| (p) | Provisions -

General -

Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognized as a finance cost.

| F-27 |

Notes to the consolidated financial statements (continued)

Provision for closure of mining units -

When the liability is initially recognized, the present value of the estimated costs is capitalized by increasing the carrying amount of the related mining assets (property, plant and equipment). Over time, the discounted liability is increased for the change in present value based on discounted rates that reflects current market assessments and the risks specify to the liability, in addition, the capitalized cost is depreciated and/or amortized based on the useful life of the asset. Any gain or loss resulting from the settlement of the obligation is recorded in the current results.

Changes in the estimated timing of rehabilitation or changes to the estimated future costs are dealt with prospectively by recognizing an adjustment to the rehabilitation liability and a corresponding adjustment to the related asset. Any reduction in the rehabilitation liability and, therefore, any deduction from the asset to which it relates, may not exceed the carrying amount of the asset. If it does, any excess over the carrying amount is taken immediately to the consolidated statements of profit or loss.

If the change in estimate results in an increase in the rehabilitation liability and, therefore, an addition to the carrying value of the asset, the Group considers whether this is an indication of impairment of the asset as a whole, and if so, tests for impairment, in accordance with IAS 36 "Impairment of Assets".

For closed mines, changes to estimated costs are recognized immediately in the consolidated statements of profit or loss.

| (q) | Treasury shares -

Own equity instruments that are reacquired (treasury shares) are recognized at cost and deducted from equity. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of the Group’s own equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognized as additional capital in equity. The voting rights related to treasury shares are cancelled for the Group and no dividends on such shares are allocated.

| (r) | Revenue recognition -

Revenue is recognized to the extent that it is probable that the economic benefits will flow to the Group and the revenue can be reliably measured, regardless of when the payment is being made. Revenue is measured at the fair value of the consideration received or receivable, taking into account contractually defined terms of payment and excluding taxes or duty. The specific recognition criteria described below must also be met before revenue is recognized:

Sales of concentrates and metals -

Revenue from sale of concentrates and metals is recognized when the significant risks and rewards of ownership of the goods have passed to the buyer, usually on delivery of the goods.

| F-28 |

Notes to the consolidated financial statements (continued)

Contract terms for the Company’s sale of metal in concentrate to customers allow for a price adjustment based on final assay results of the metal in concentrate by the customer to determine the final content. These are referred to as provisional pricing arrangements and are such that the selling price for metal in concentrate is based on prevailing spot prices on a specified future date after shipment to the customer (the quotation period). Adjustments to the sales price occurs based on movements in quoted market prices up to the date of final settlement. The period between provisional invoicing and final settlement can be between one and six months.

Sales contracts for metal in concentrate that have provisional pricing features are considered to contain an embedded derivative, which is required to be separated from the host contract for accounting purposes. The host contract is the sale of metals in concentrate, and the embedded derivative is the forward contract for which the provisional sale is subsequently adjusted with final liquidations. The embedded derivative is originated by the metals prices since the date of issuance of issuance of the provisional liquidation until the date of issuance of the final liquidation.

The embedded derivative, which does not qualify for hedge accounting, is initially recognized at fair value with subsequent changes in the fair value recognized in the consolidated statements of profit or loss until final settlement, and presented as part of net sales. Changes in fair value over the quotation period and up until final settlement are estimated by reference to forward market prices.

Interest income -

For all financial instruments measured at amortized cost, interest income is recorded using the effective interest rate (EIR). EIR is the rate that exactly discounts the estimated future cash payments or receipts over the expected life of the financial instrument or a shorter period, where appropriate, to the net carrying amount of the financial asset or liability. Interest income is included in finance income in the consolidated statements of profit or loss.

Royalty income -

The royalty income is recognized in accordance with the accrual method considering the substance of the relevant agreements.

Dividends -

Revenue is recognized when the Group's right to receive the payment is established, which is generally when shareholders approve the dividend.

Revenue from engineering and construction services -

Revenue is recognized based on the stage of completion of contracts for existing services. The stage of completion is measured by reference to services performed to date as a percentage of total services to be performed by each contract.

Rental income -

Rental income arising from operating leases on investment properties is accounted for on a straight-line basis over the lease term and is included in revenue in the consolidated statement of profit or loss due to its operating nature.

| (s) | Benefits to employees -

Salaries and wages, bonuses, post-employment benefits and vacations are calculated in accordance with IAS 19, "Employee Benefits" and are calculated in accordance with current Peruvian legislation based on the accrual basis.

Workers’ profit sharing

The Company recognizes workers’ profit sharing in accordance with IAS 19, “Employees Benefits". Workers' profit sharing is calculated in accordance with the Peruvian law (Legislative Decree No. 892), and the applicable rate is 8% over the taxable net base of current year. According to Peruvian law, the limit in the workers' profit sharing that an employee can receive is equivalent to 18 months of wages, and any excess above such limit has be transferred to the Regional Government and “National Fund for Employment’s Promotion and Training” (“FONDOEMPLEO”). The Company’s workers’ profit sharing is recognized as a liability in the statement of financial position and as an operating expense in the statements of comprehensive income.

Notes to the consolidated financial statements (continued)

| (t) | Borrowing costs -

Costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as finance part of the cost of an asset. A qualifying asset is one whose value is greater than US$5 million and requires a longer period to 12 months to get ready for its intended use. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consist of interest and other costs that the Group incurs in connection with the borrowing of funds.

| (u) | Taxes –

Current income tax -

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid or the tax authority. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting period.

Current income tax relating to items recognized directly in equity is recognized in equity and not in the consolidated statements of profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred income tax -

Deferred income tax is provided using the liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred income tax liabilities are recognized for all taxable temporary differences, except for taxable temporary differences associated with investments in associates, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred income tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted at the reporting date.

Deferred tax items are recognized in correlation to the underlying transaction either in other comprehensive income or directly in equity.

| F-31 |

Notes to the consolidated financial statements (continued)

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right to compensate current tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Peruvian mining royalties and special mining tax -

Mining royalties and special mining tax are accounted for in accordance with IAS 12 “Income Tax” because they have the characteristics of an income tax. This is considered to be the case when they are imposed under government authority and the amount payable is based on taxable income-rather than physical quantities produced or as a percentage of revenue-after adjustment for temporary differences. Legal rules and rates used to calculate the amounts payable are those in effect on the date of the consolidated statements of financial position.

Therefore, obligations arising from Mining Royalties and Special Mining Tax are recognized as income tax under the scope of IAS 12. Both, Mining Royalties and Special Mining Tax generated deferred assets and liabilities which must be measured using the average rates expected to apply to operating profit in the quarter in which the Group expects to reverse temporary differences.

Sales tax -

Expenses and assets are recognized net of the amount of sales tax, except:

| (i) | When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable;
| (ii) | When receivables and payables are stated with the amount of sales tax included.

The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the consolidated statements of financial position.

| (v) | Fair value measurement

The Group measures its financial instruments, such as, derivatives and embedded derivatives, at fair value at the date of the consolidated statements of financial position.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

| - | In the principal market for the asset or liability, or

| - | In the absence of a principal market, in the most advantageous market for the asset or liability.

The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

| F-32 |

Notes to the consolidated financial statements (continued)

All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described, as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

| - | Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities;

| - | Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable;

| - | Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For assets and liabilities that are recognized in the consolidated financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by reassessing categorization (based on the lowest-level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

The Group's Management determines the policies and procedures for both recurring fair value measurement and non-recurring measurement. At each reporting date, the Group's Management analyzes the movements in the values of assets and liabilities which are required to be re-measured or re-assessed as per the Group’s accounting policies.

For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

| (w) | Derivative financial instruments and hedge accounting -

Initial recognition and subsequent measurement –

The Group uses derivative instruments to hedge its commodity price risk (forward commodity contracts) and its foreign exchange risk (forward exchange rate contracts). Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

At the inception of the hedge relationship, the Group formally designates and documents the hedge relationship to which it wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge.

The documentation includes identification of the hedging instrument, the hedge item or transaction, the nature of the risk being hedged and how the entity will assess the effectiveness of changes in the hedging instrument’s fair value in offsetting the exposure to changes in cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in cash flows and are assessed on an ongoing basis to determine that they actually have been highly effective throughout the financial reporting periods for which they were designated.

| F-33 |

Notes to the consolidated financial statements (continued)

The Group’s hedge is classified as cash flow hedge. The effective portion of gain or loss on the hedging instrument is initially recognized in the consolidated statements of changes in equity, under the caption other equity reserves, while the ineffective portion is recognized immediately in the consolidated statements of profit or loss in the finance costs caption.

| (x) | Discontinued operations -

The Group classifies disposal groups as held for sale if their carrying amounts will be recovered principally through sale rather than through continuing use. Such disposal groups classified as held for sale are measured at the lower of their carrying amount and fair value less costs to sell.

The criteria for held for sale classification is regarded as met only when the sale is highly probable and the disposal group is available for immediate sale in its present condition. Actions required to complete the sale should indicate that it is unlikely that significant changes to the plan will be made or that the sale will be withdrawn. Management must be committed to the sale expected within one year from the date of the classification.

An extension of the period required to complete a sale does not preclude an asset (or disposal group) from being classified as held for sale if the delay is caused by events or circumstances beyond the entity’s control and there is sufficient evidence that the entity remains committed to its plan to sell the asset.

Property, plant and equipment are not depreciated or amortized once classified as held for sale.

Assets and liabilities classified as held for sale are presented separately as current items in the consolidated statement of financial position.

A disposal group qualifies as discontinued operation if it is a component of an entity that either has been disposed of, or is classified as held for sale, and:

| - | Represents a separate major line of business or geographical area of operations;

| - | Is part of a single coordinated plan to dispose of a separate major line of business or geographical area of operations; or

| - | Is a subsidiary acquired exclusively with a view to resale.

Discontinued operations are excluded from the results of continuing operations and are presented as a single amount as profit or loss after tax from discontinued operations in the consolidated statement of profit or loss.

Additional disclosures are provided in Note 1(e). All other notes to the consolidated financial statements include amounts for continuing operations, unless otherwise mentioned.

| 3. | Significant judgments, estimates and assumptions

The preparation of the Group’s consolidated financial statements requires Management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. The estimates and assumptions are continuously evaluated and based on Management´s experience and other facts, including the expectations about future events which are reasonable under current situation. Uncertainty about these estimates and assumptions could result in outcomes that require material adjustment to the carrying amount of assets and liabilities affected in future periods. Further information on each of these areas and how they impact the various accounting policies are described below and also in the relevant notes to the consolidated financial statements.

| F-34 |

Notes to the consolidated financial statements (continued)

| 3.1. | Judgments

In the process of applying the Group’s accounting policies, Management has made the following judgments, which have the most significant effect on the amounts recognized in the consolidated financial statements:

| (a) | Contingencies -

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential quantum of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

| (b) | Development start date -

The Group assesses the status of each exploration project of its mining units to determine when the development phase begins. One of the criteria used to evaluate the development start date is when the Group determines that the property can be economically developed.

| F-35 |

Notes to the consolidated financial statements (continued)

| (c) | Production start date -

The Group assesses the stage of each mine under development to determine when a mine moves into the production phase. The criteria used to assess the start date are determined based on the unique nature of each mining project, such as the complexity of the project and its location. The Group considers various relevant criteria to assess when the production phase is considered to have commenced. Some of the criteria used to identify the production start date include, but are not limited to:

| - | Level of capital expenditure incurred compared to the original construction cost estimates;

| - | Completion of a reasonable period of testing of the mine plant and equipment;

| - | Ability to produce metal in saleable form (within specifications);

| - | Ability to sustain ongoing production of metal.

When a mine development /construction project moves into the production phase, the capitalization of certain mine development costs ceases and costs are either regarded as forming part of the cost of inventory or expensed, except for costs that qualify for capitalization relating to mining asset additions or improvements. It is also at this point that depreciation or amortization commences.

| 3.2. | Estimates and assumptions

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Group based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market change or circumstances arising beyond the control of the Group. Such changes are reflected in the assumptions when they occur.

| (a) | Determination of mineral reserves and resources -

The Group calculates its reserves using methods generally applied by mining and industry according to international guidelines. All estimated reserves represent estimated quantities of mineral proven and probable that under current conditions can be economically and legally processed.

The process of estimating quantities of reserves is complex and requires making subjective decisions when evaluating all geological, geophysical, engineering and economic information available choices. Reviews could occur on reserve estimates due to, among others, revisions to the data or geological assumptions, changes in prices, production costs and results of exploration activities. Changes in estimated reserves could mainly affect the carrying value of mining concessions, development costs and property, plant and equipment; the charges in result for depreciation and amortization; and the carrying amount of the provision for closure of mining units.

| (b) | Units of production depreciation -

Estimated economically recoverable reserves are used in determining the depreciation and/or amortization of mine-specific assets.

This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life-of-mine production. The life of each item, which is assessed at least annually, has regard to both its physical life limitations and present assessments of economically recoverable reserves of the mine property at which the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes in estimates are accounted for prospectively.

| F-36 |

Notes to the consolidated financial statements (continued)

| (c) | Mine rehabilitation provision -

The Group assesses its mine rehabilitation provision at each reporting date. The ultimate rehabilitation costs are uncertain, and cost estimates can vary in response to many factors, including estimates of the extent and costs of rehabilitation activities, technological changes, regulatory changes, cost increases as compared to the inflation rates, and changes in discount rates. These uncertainties may result in future actual expenditure differing from the amounts currently provided. The provision at reporting date represents Management’s best estimate of the present value of the future rehabilitation costs required.

| (d) | Inventories, net -

Inventories are classified in short and long term in accordance with the time that Management estimates will start the production of the concentrate extracted from the mining unit.

Net realizable value tests are performed at each reporting date and represent the estimated future sales price of the product the entity expects to realize when the product is processed and sold, less estimated costs to complete production and bring the product to sale.

| (e) | Impairment of non-financial assets -

The Group assesses each asset or cash generating unit in each reporting period to determine whether any indication of impairment exists. Where an indicator of impairment exists, a formal estimate of the recoverable amount is made, which is considered to be the higher of the fair value less costs of disposal and value in use. The assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates, operating costs, among others. These estimates and assumptions are subject to risk and uncertainty.

| F-37 |

Notes to the consolidated financial statements (continued)

The fair value of mining assets is generally calculated by the present value of future cash flows arising from the continued use of the asset, which include some estimates, such as the cost of future expansion plans, using assumptions that a third party might consider. The future cash flows are discounted to their present value using a discount rate that reflects current market assessment of the value of money over time, as well as specific risks of the asset or cash-generating unit under evaluation.

The Group has determined the operations of each mining unit as a single cash generating unit.

| (f) | Taxes -

Deferred tax assets are recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized. Significant Management judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits together with future tax planning strategies.

| (g) | Fair value of contingent consideration -

The contingent consideration arising from a business combination is measured at fair value at the date of acquisition, as part of the business combination. If the contingent consideration is eligible to be recognized as a financial liability the fair value is subsequently re-measured at each date of the consolidated financial statements. Determining the fair value of the contingent consideration is based on a model of discounted future cash flows. The key assumptions take into account the likelihood of achieving each goal of financial performance as well as the discount factor.

| 4. | Standards issued but not effective

The relevant standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Group’s financial statements are disclosed below. The Group intends to adopt these standards, if applicable, when they become effective.

IFRS 9 Financial Instruments

In July 2014, the IASB issued the final version of IFRS 9 Financial Instruments which reflects all phases of the financial instruments project and replaces IAS 39 and all previous versions of IFRS 9. IFRS 9 brings together all three aspects of the accounting for financial instruments project: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for annual periods beginning on or after January 1, 2018, with early application permitted. Except for hedge accounting, retrospective application is required, but the provision of comparative information is not compulsory. For hedge accounting, the requirements are generally applied prospectively, with some limited exceptions.

The adoption of IFRS 9 would have not significant effect on the classification and measurement of the Group’s financial assets and liabilities.

| F-38 |

Notes to the consolidated financial statements (continued)

IFRS 15 Revenue from Contracts with Customers

IFRS 15 was issued in May 2014 and establishes a new five-step model that will apply to revenue arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. The principles in IFRS 15 provide a more structured approach to measuring and recognizing revenue. The new revenue standard is applicable to all entities and will supersede all current revenue recognition requirements under IFRS. Either a full retrospective application or a modified retrospective application is required for annual periods beginning on or after January 1, 2018. Early adoption is permitted. The Group is currently assessing the impact of IFRS 15 and plans to adopt the new standard on the required effective date.

Amendments to IFRS 10 and IAS 28: Sale or Contribution of Assets between an Investor and its Associate or Joint Venture

The amendments address the conflict between IFRS 10 Consolidated Financial Statements and IAS 28 in dealing with the loss of control of a subsidiary that is sold or contributed to an associate or joint venture. The amendments clarify that the gain or loss resulting from the sale or contribution of assets that constitute a business, as defined in IFRS 3, between an investor and its associate or joint venture, is recognized in full. Any gain or loss resulting from the sale or contribution of assets that do not constitute a business, however, is recognized only to the extent of unrelated investors’ interests in the associate or joint venture. These amendments must be applied prospectively and are effective for annual periods beginning on or after January 1, 2016, with early adoption permitted. These amendments will impact the Group to the extent that it undertakes future transactions of this nature, as this accounting approach differs to that which it would currently apply.

| 5. | Business combination

Acquisition of controlling interest in Canteras del Hallazgo S.A.C. -

On August 18, 2014, Buenaventura acquired from Minera Gold Fields Peru S.A. (“Gold Fields”) 51% of the voting shares of Canteras del Hallazgo S.A.C., which represent the whole interest of Gold Fields in the equity of such entity.

Canteras del Hallazgo is a privately-held entity incorporated in 2009 and owner of the Chucapaca project, which is located in the Ichuña district, in the General Sanchez Cerro province, in the Moquegua department, Peru. According to previously performed studies, there is evidence of the existence of gold, silver, copper and antimony in the area, specifically in the Canahuire deposit.

The purchase consideration amounted to:

|  | US$(000) |
Cash paid |  |  | 81,000 |
Contingent consideration liability |  |  | 23,026 |
As of December 31, 2014 |  |  | 104,026 |

Moreover, the Group recognized a gain of US$59,852,000 in the 2014 consolidated statement of profit or loss as a result of re-measuring the previously held equity interest (US$40,094,000) at its acquisition date fair value (US$99,946,000) in accordance with IFRS 3.

| F-39 |

Notes to the consolidated financial statements (continued)

Assets acquired and liabilities assumed -

The fair values of the identifiable assets and liabilities assumed of Canteras del Hallazgo S.A.C. as at the date of acquisition were:

|  | US$(000) |
Assets |  |  |  |
Cash and cash equivalents |  |  | 684 |
Income tax credit |  |  | 29 |
Value added tax credit |  |  | 10,599 |
Mining concessions, property, plant and equipment, net |  |  | 202,658 |
|  |  | 213,970 |
Liabilities |  |  |  |
Deferred income tax liabilities, net |  |  | 9,235 |
Trade and other payables and provisions |  |  | 724 |
|  |  | 9,959 |
Total identifiable net assets at fair value |  |  | 204,011 |

Contingent consideration -

The purchase and sale agreement considered a contingent consideration of US$23,026,000, which corresponds to the present value of the future royalty payments equivalent to 1.5% over the future sales of the minerals arising from the mining properties acquired. The fair value has been determined using the income approach. Significant unobservable valuation inputs are provided below:

Annual average of future sales of mineral (US$000) |  |  | 208,574 |
Useful life of mining properties |  |  | 12 |
Discount rate (%) |  |  | 10 |

Significant increase (decrease) in the future sales of mineral would result in higher (lower) fair value of the contingent consideration liability, while significant increase (decrease) in the discount rate would result in lower (higher) fair value of the liability. Changes in the fair value of this contingent consideration have been recognized through profit or loss in the consolidated statement of profit or loss.

| F-40 |

Notes to the consolidated financial statements (continued)

As of December 31, 2015, it is highly probable that the Group reaches the projected future sales. The fair value of the contingent consideration determined as of December 31, 2015 reflects this assumption and changes in metal prices. A reconciliation of fair value measurement of the contingent consideration liability is provided below:

|  | US$(000) |
As of January 1, 2014 |  |  | - |
Liability arising on business combination |  |  | 23,026 |
As of December 31, 2014 |  |  | 23,026 |
Unrealized fair value changes recognized in profit or loss |  |  | (6,032 | )
As of December 31, 2015 |  |  | 16,994 |

The Group has the preferential right of acquisition of the royalty in case Gold Fields decides to sell it.

Merger -

On September 22, 2014, the General Shareholders’ meeting of the Company approved the merger of the Company (absorbing entity) and its subsidiary Canteras del Hallazgo S.A.C. (absorbed entity) effective December 3, 2014.

The statement of profit or loss of Canteras del Hallazgo S.A.C. for the eleven-month period ended December 3, 2014 is a follows:

|  | US$(000) |
Administrative expenses |  |  | (2,344 | )
Net loss from currency exchange difference |  |  | (2,319 | )
Net loss |  |  | (4,663 | )

| (b) | Trade accounts receivable are denominated in U.S. dollars, are neither due nor impaired, do not yield interest and have no specific guarantees.

| (c) | This item mainly corresponds to value added tax pending to be refunded as of December 31, 2015 and 2014. In November 2013 and January 2015, Buenaventura filed claims procedures by S/19,500,000 (equivalent to US$6,541,000) and by S/71,100,000 (equivalent to US$20,862,000), respectively, in connection with undue offsets made by the tax authorities against tax debts of prior years. In January 2016, Buenaventura collected S/71,100,000 after the tax authorities accepted the appeal; the resolution of the appeal process related to the S/19,500,000 claim is pending.

|  | In the opinion of the Group’s legal advisors, the tax offset made by the tax authorities have no legal support, so there are enough arguments to obtain a favorable outcome in the claim process initiated by the Group.

| (d) | Corresponds to deposits held in the Peruvian State bank which only can be used to offset tax obligations.

| (e) | The provision for doubtful accounts has shown no movement during the years 2015, 2014 and 2013. In the opinion of the Group’s Management, the balance of the provision for doubtful accounts is sufficient to cover adequately the risks of failure to date of the consolidated statement of financial position.

Notes to the consolidated financial statements (continued)

Investments held by the Group in its associates Minera Yanacocha S.R.L.

The following relevant information on these investments is as follows:

Investment in Minera Yanacocha S.R.L. -

The Company, through its subsidiary Compañía Minera Condesa S.A., has an interest of 43.65% of Yanacocha. Yanacocha is engaged in gold production and exploration and development of gold and copper in its own concessions or owned by S.R.M.L. Chaupiloma Dos de Cajamarca, with which it signed a contract for use of mineral rights.

During the last several years, Yanacocha has been developing the Conga project, which consists of two deposits of gold and porphyry of copper located at northeast of the Yanacocha operating area in the provinces of Celendín, Cajamarca and Hualgayoc (Peru).

Because of local communities and political protests for potential water impacts of the project development activities and construction the projects are suspended since November 2011. To date, Yanacocha’s management has been making only water support activities recommended by independent experts, mainly the construction of water reservoirs, before carrying out any development project.

During the years 2014 and 2013, Yanacocha recorded impairment charges of its long-lived assets, net of tax, of US$378,799,000 and US$726,984,000, respectively, which reduced Yanacocha´s net equity and, therefore, the equity participation of the Group in this associate in those years. These impairment losses mainly resulted from the postponement of the development activities due to the serious difficulties to get the social license to operate the Conga project.

In December 2015, Yanacocha recorded charges for deferred income tax recoverability by US$510,000,000 since Management considers it improbable that taxable profit will be available to compensate against the deductible temporary differences.

In February 2016, the Committee agreed unanimously the distribution to the partners, in proportion to its social share, of US$ 300 million, which correspond to the portion of the retained earnings as of December 31, 2014, originated in 2011.

| (b) | Impairment of long-lived assets

I n accordance with its accounting policies and processes, each asset or CGU is evaluated annually at year end to determine whether there are any indications of impairment. If any such indications of impairment exist, a formal estimate of the recoverable amount is performed.

In assessing whether impairment is required, the carrying value of the asset or CGU is compared with its recoverable amount. The recoverable amount is the higher of the CGU’s fair value less costs of disposal (FVLCD) and value in use (VIU). Given the nature of the Group’s activities, information on the fair value of an asset is usually difficult to obtain unless negotiations with potential purchasers or similar transactions are taking place. Consequently, the recoverable amount for each CGU is estimated based on discounted future estimated cash flows expected to be generated from the continued use of the CGUs using market based commodity price and exchange assumptions, estimated quantities of recoverable minerals, production levels, operating costs and capital requirements, and its eventual disposal, based on the latest life of mine (LOM) plans. These cash flows were discounted using a real pre-tax discount rate that reflected current market assessments of the time value of money and the risks specific to the CGU.

The estimates of quantities of recoverable minerals, production levels, operating costs and capital requirements are obtained from the planning process, including the LOM plans, one-year budgets and CGU-specific studies.

As a result of the recoverable amount analysis performed during the year, the Group recognized impairment losses related to mine properties for US$11,255,000, in relation to La Zanja and Breapampa mining units.

Key assumptions

The determination of value in use is most sensitive to the following key assumptions:

• Production volumes;

• Commodity prices;

• Discount rate.

Production volumes: Estimated production volumes are based on detailed life-of-mine plans and take into account development plans for the mines agreed by management as part of planning process. Production volumes are dependent on a number of variables, such as: the recoverable quantities; the production profile; the cost of the development of the infrastructure necessary to extract the reserves; the production costs; the contractual duration of mining rights; and the selling price of the commodities extracted.

As each producing mining unit has specific reserve characteristics and economic circumstances, the cash flows of the mines are computed using appropriate individual economic models and key assumptions established by management. The production profiles used were consistent with the reserves and resource volumes approved as part of the Group’s process for the estimation of proved and probable reserves and resource estimates.

Commodity prices: Forecast commodity prices are based on management’s estimates and are derived from forward price curves and long-term views of global supply and demand, building on past experience of the industry and consistent with external sources. These prices were adjusted to arrive at appropriate consistent price assumptions for the different qualities and type of commodities, or, where appropriate, contracted prices were applied. These prices are reviewed at least annually.

Estimates prices for the current and long-term periods that have been used to estimate future revenues are as follows:

|  | 2016 |  |  | 2017 |  |  | 2018 |  |  | 2019 |
|  | US$ |  |  | US$ |  |  | US$ |  |  | US$ |

Silver |  |  | 15.05 | /OZ |  |  | 16.24 | /OZ |  |  | 17.34 | /OZ |  |  | 18.18 | /OZ
Copper |  |  | 5,050 | /MT |  |  | 5,250 | /MT |  |  | 5,500 | /MT |  |  | 5,194 | /MT
Lead |  |  | 1,800 | /MT |  |  | 1,875 | /MT |  |  | 1,995 | /MT |  |  | 1,819 | /MT
Zinc |  |  | 1,830 | /MT |  |  | 1,935 | /MT |  |  | 2,000 | /MT |  |  | 1,870 | /MT

Discount rate: In calculating the value in use, a pre-tax discount rate of 10.03% was applied to the pre-tax cash flows. This discount rate is derived from the Group’s post-tax weighted average cost of capital (WACC), with appropriate adjustments made to reflect the risks specific to the CGU. The WACC takes into account both debt and equity. The cost of equity is derived from the expected return on investment by the Group’s investors. The cost of debt is based on its interest bearing borrowings the Group is obliged to service. The beta factors are evaluated annually based on publicly available market data.

| (c) | The book value of assets held under finance leases amounted to US$226,429,000 at December 31, 2015 (US$233,826,000 at December 31, 2014) and is presented in various items of property, plant and equipment. Additions during the year include US$262,000 (US$142,315,000 during the year 2014). Leased assets are pledged as security for the related finance lease liabilities.

| (d) | The amount of capitalized finance costs during the year 2015 was US$1,307,000 (US$20,079,000 during 2014) and is presented under investing activities in the consolidated statements of cash flows. The average rate used to determine the financial cost to be capitalized was 3.90% during 2015.

Notes to the consolidated financial statements (continued)

The provision for closure of mining units and exploration projects represents the present value of the closure costs that are expected to be incurred between the years 2016 and 2040. These estimates are based on studies prepared by independent advisers that meet the environmental regulations in effect.

The provision for closure of mining units and exploration projects corresponds mostly to activities that must be carried out for restoring the mining units and areas affected by operation and production activities. The principal works to be performed correspond to earthworks, re-vegetation efforts and dismantling of the plants. Closure budgets are reviewed regularly to take into account any significant change in the studies conducted. Nevertheless, the closure costs of mining units will depend on the market prices for the closure works required, which would reflect future economic conditions. Also, the time when the disbursements will be made depends on the useful life of the mine, which will be based on future metals prices.

As of December 31, 2015, the future value of the provision for closure of mining units and exploration projects was US$212,362,000, which has been discounted using annual risk-free rates ranging from 0.72% to 5.21% in periods of 1 to 24 years, resulting in an updated liability of US$166,403,000 (US$103,010,000 as of December 31, 2014). The Group believes that this liability is sufficient to meet the current environmental protection laws approved by the Ministry of Energy and Mines.

As of December 31, 2015, the Group has constituted letters of credit in favor of the Ministry of Energy and Mines for US$110,403,000 (US$76,808,000 as of December 31, 2014) to secure mine closure plans of its mining units.

| (c) | Legal reserve -

The Peruvian Corporations Law requires that a minimum of 10% of the distributable earnings for each period, after deducting the income tax, be transferred to a legal reserve until the latter is equal to 20% of the capital stock. This legal reserve can be used to offset losses or may be capitalized, with the obligation, in both cases, to replenish it.

Although, the balance of the legal reserve exceeded the limit mentioned above, the Company increased its legal reserve by US$47,000 in 2014.

| (d) | Dividends declared and paid -

The table below presents the dividends declared and paid in 2014 and 2013:

| F-61 |

Notes to the consolidated financial statements (continued)

The calculation of loss per share attributable to the equity holders of the parent is presented below:

|  | 2015 |  |  | 2014 |  |  | 2013 |
Loss net (numerator) - US$ |  |  | (317,210,000 | ) |  |  | (76,065,000 | ) |  |  | (107,257,000 | )
Total common and investment shares (denominator) |  |  | 254,186,867 |  |  |  | 254,186,867 |  |  |  | 254,186,867 |
Loss net per basic share and diluted - US$ |  |  | (1.25 | ) |  |  | (0.30 | ) |  |  | (0.42 | )

Loss net per basic share and diluted - US$ |  |  | (1.21 | ) |  |  | (0.18 | ) |  |  | (0.09 | )

Notes to the consolidated financial statements (continued)

| 20. | Tax situation

| (a) | Current tax regime -

The Company and its Peruvian subsidiaries are subject to the Peruvian tax regime. In 2015, the income tax rate for enterprises is 28% over the taxable income. Non-domiciled companies in Peru or natural persons are affected to a withholding income tax of 4.1% over the dividends received.

By means of Law No. 30296 enacted on December 31, 2014, the Peruvian government introduced certain amendments to the Income Tax Law, effective January 1, 2015. The most relevant are listed below:

| - | There will be a gradual reduction of the corporate income tax from 30% to 28% in 2015 and 2016; to 27% in 2017 and 2018; and to 26% in 2019 and thereafter;

| - | There will be a gradual increase of the withholding income tax to dividends from 4.1% to 6.8% in 2015 and 2016; to 8.0% in 2017 and 2018; and to 9.3% in 2019 and thereafter. These rates will be applicable to the distributed or approved dividends, whichever first occurs, effective January 1, 2015;

| - | The retained earnings or other items that can generate taxable dividends, obtained until December 31, 2014, will be subject to a rate of 4.1%.

| (b) | Years open to tax review -

During the four years following the year of filing the tax return, the tax authorities have the power to review and, as applicable, correct the income tax computed by the Group. The Income Tax and Value Added Tax returns for the following years are open to review by the Tax Authorities:

Entity | Years open to review band Tax Authorities

Notes to the consolidated financial statements (continued)

Due to the possible interpretations that the Tax Authorities may give to legislation in effect, it is not possible to determine whether or not any of the tax audits will result in increased liabilities for the Group. For that reason, any tax or surcharge that could arise from future tax audits would be applied to the income of the period in which it is determined. In management's opinion and its legal advisors, any possible additional payment of taxes in the entities mentioned before would not have a material effect on the consolidated financial statements as of December 31, 2015 and 2014.

The open tax process of the Group and its associates are presented in Note 29 (g).

| (c) | Tax-loss carryforwards -

The tax-loss carryforward determined by the Group amounts to approximately S/688,178,000 and S/622,419,000 as of December 31, 2015 and 2014, respectively (equivalent to US$201,634,000 and US$208,237,000 respectively). As permitted by the Income Tax Law, the Group has chosen a system that permits to offset these losses with an annual cap equivalent to 50% of net future taxable income.

The Group has decided to recognize a deferred income tax asset related to the tax-loss carryforward, due to there it is more likely than not that the tax-loss carryforward can be used to compensate future taxable net income.

| (d) | Transfer pricing -

For purposes of determining the Income Tax, the transfer prices for transactions with related companies and companies domiciled in territories with little or no taxation must be supported with documentation and information on the valuation methods used and the criteria considered for their determination. Tax Administration can request this information based on analysis of the Group's operations. The Group’s Management and its legal advisers believe that, as a result of the application of these standards, no material contingencies will arise for the Group as of December 31, 2015 and 2014.

Notes to the consolidated financial statements (continued)

| (e) | Related to the investment in associates, the Group has not recognized a deferred income tax asset by US$94,528,000 as of December 31, 2015 originated by the difference between the financial and taxable basis of these investments (US$47,623,000 as of December 31, 2014). Management believes that the timing differences will be reversed in the future without taxable effects. There is no legal or contractual obligation that would require the Company’s Management to sell its investment in its associates (which event would result in a taxable capital gain based on current tax law).

| 29. | Commitments and contingencies

Commitments

| (a) | Environmental –

The Group’s exploration and exploitation activities are subject to environmental protection standards.

Law No. 28090 regulates the obligations and procedures that must be met by the holders of mining activities for the preparation, filing and implementation of Mine Closure Plans, as well as the establishment of the corresponding environmental guarantees to secure fulfillment of the investments, subject to the principles of protection, preservation and recovery of the environment.

Law No. 28271 regulates environmental liabilities in mining activities. This Law has the objective of ruling the identification of mining activity’s environmental liabilities and financing the remediation of the affected areas. According to this law, environmental liabilities refer to the impact caused to the environment by abandoned or inactive mining operations.

The Group considers that the recorded liability is sufficient to meet the current regulatory environment in Peru.

| (b) | Leased concessions -

The Group pays 10% on the valued production of mineral obtained from the concessions leased by Sindicato Minero Orcopampa S.A. This concession is in force until the year 2043. See Note 24.

| (c) | Letter of guarantee granted by Buenaventura -

Letter of guarantee - Huanza

On December 2, 2009, Banco de Credito del Perú signed a finance lease contract for US$119 million with Consorcio Energético de Huancavelica S.A., Empresa de Generación Huanza S.A. and Buenaventura. This financing is in favor of Empresa de Generación Huanza S.A., and is guaranteed by Buenaventura. On February 8, 2016, the bank released the guarantee granted by Buenaventura.

Contingencies

| (f) | Legal procedures -

Buenaventura -

Buenaventura is a party in legal procedures that have arisen in the normal course of its activities. Nevertheless, in the opinion of Buenaventura’s Management, none of these procedures, individually or as a whole, could result in material contingencies for the consolidated financial statements.

| F-77 |

Notes to the consolidated financial statements (continued)

The possible contingencies amount to US$2,031,000 and US$1,573,000 as of December 31, 2015 and 2014, respectively.

Yanacocha -

Mercury spill in Choropampa

In June 2000, a carrier hired by Yanacocha spilled approximately 151 kilograms of mercury in the vicinity of the town of Choropampa, Peru, located 85 kilometers (53 miles) southeast of the mine. To date, Yanacocha has held court settlements with people affected by the incident. At December 31, 2015, there are 6 applicants with pending process. Yanacocha cannot reasonably predict the outcome of any of these claims; however, it is estimated that the maximum additional expense related to these demands will be US$1.5 million.

Action for Constitutional Relief against Conga Project Exploitation

On October 19, 2012, Marco Antonio Arana Zegarra ("Marco Arana") initiated an action for constitutional relief against the Mines and Energy Ministry and Yanacocha requesting that the Court orders to cease any threats of violation to life in an adequate and balanced environment; so that Court declare the suspension of the exploitation of the Conga Project and avoid Directorial Resolution No.351-2010-MEM/AM dated on October 27, 2010 that approved the Conga Environmental Impact Assessment.

By Court resolution No.1 dated October 23, 2012, the action was dismissed. On November 5, 2012, resolution No.1 was appealed by plaintiff and the hearing at Superior Court was held on March 4, 2013. The Cajamarca Superior Court confirmed the ruling of the judge that dismissed the claim.

On May 23, 2013, Marco Arana filed for a Constitutional remedy against the Cajamarca Superior Court decision and on June 3, 2013, the Cajamarca Superior Court accepted the Constitutional remedy filed by Marco Arana and the file has been sent to the Constitutional Court. On September 25, 2013, the Constitutional Court heard oral arguments from the parties and we are waiting their decision. To date the case maintains the same status.

(g) Open tax procedures –

Buenaventura -

| - | During 2012 and 2014, the tax authority (SUNAT) reviewed the income tax for 2007 and 2008. As a result, SUNAT do not recognize tax declared deductions by S/1,056,310,000 (equivalent to US$309,493,000) in 2007 and S/1,530,985,000 (equivalent to US$448,575,000) in 2008. The main unrecognized deduction is the payment made for the removal of the price component of its commercial contracts of gold. In the opinion of management and its legal counsel, the objections are unfounded so Buenaventura should get a favorable result in the initiated claim process.

| - | During 2015, the tax authorities reviewed the income tax of 2009 and 2010. As a result, they did not recognize Buenaventura declared tax deductions by S/76,023,000 (equivalent to US$22,275,000). The main unrecognized deductions by Buenaventura are: the non-deductibility of bonuses paid to contractors, a provision of doubtful accounts not accepted as an expense and income unduly deducted. The possible contingencies for the years 2009 and 2010 amount to S/525,921,000 (equivalent to US$154,093,000) as of December 31, 2015. In the opinion of Management and its legal counsel, the Company should get a favorable result in the initiated claim process (by 2009) and will start (by 2010).

| - | During 2015, the tax authorities reviewed the income tax of the subsidiary Buenaventura Ingenieros S.A (BISA) for the fiscal years 2011 and 2012. The main unrecognized deductions are related to the deduction of bonuses paid to staff as well as the omission of income from transfer of fuel to suppliers, amounting to S/21,034,000 (equivalent to US$6,163,000). In addition, the tax authority requires the payment of the value added tax related to allegedly omitted revenues in the transfer of fuel to suppliers. The possible contingencies for income tax for the years 2011 and 2012 amount to S/9,471,000 (equivalent to US$2,775,000) and for the value added tax amount to S/3,467,000 (US$1,016,000) as of December 31, 2015. In the opinion of Management of this subsidiary and its legal advisors, BISA should get a favorable result in the initiated claim process (for income tax of 2011 and value added tax for the years 2011 and 2012) and in the claim to be initiated (for income tax of 2012).

| - | During the years 2014 and 2015, the tax authority issued tax assessments for the income tax of the subsidiary Sociedad Minera El Brocal S.A.A. (El Brocal) for the years 2011 and 2012. The main objections are related to the deduction of the derivative financial instruments loss and the tax treatment of the mining royalties and amount to S/11,586,000 (equivalent to US$3,395,000). With respect to the objections of 2011, El Brocal decided to pay under protest the income tax assessment by S/8,333,000 (equivalent to US$2,442,000) so it can have access to a discount benefit of the fine and appealed to the Tax Court. In connection with the possible tax debt of 2012 by S/3,576,000 (equivalent to US$1,048,000), El Brocal has appealed to the Tax Court. In the opinion of Management of the subsidiary and its legal advisors, El Brocal should get a favorable result in the initiated claim process.

| - | In addition, the tax authority has issued tax assessments as a result of the audit of other subsidiaries of the Group by S/12,096,000 (equivalent to US$3,544,000). In the opinion of Management and its legal counsel, the assessments are of possible occurrence; however, management of the subsidiaries expects to get a favorable result in the initiated claim process.

Cerro Verde –

| - | Mining Royalties

SUNAT, the Peruvian tax authority, has assessed mining royalties on materials processed by Cerro Verde´s concentrator, which commenced operations in late 2006. These assessments cover the period December 2006 to December 2007 and the years 2008 and 2009. In July 2013, the Peruvian Tax Tribunal issued two decisions affirming assessments for the period December 2006 through December 2008. Decisions by the Tax Tribunal ended the administrative stage of the appeal procedures for these assessments.

In September 2013, Cerro Verde filed judiciary appeals related to the assessments because Cerro Verde believes that its 1998 stability agreement exempted all minerals extracted from its mining concessions from royalties, irrespective of the method used for processing those minerals. With respect to the judiciary appeal related to the assessment for the year 2008, on December 17, 2014, the Eighteenth Contentious Administrative Court rendered its decision upholding Cerro Verde’s position and nullifying SUNAT’s assessment and the Tax Tribunal´s resolution (S/.106.4 million). In December 2014, SUNAT and the Tax Court appealed this decision. The court’s position also invalidates all penalties and interest assessed by SUNAT for that period (S/.139.7 million). On January 29, 2016, the 6th Superior Justice Court nullified the decision of the Eighteenth Contentious Administrative Court. Cerro Verde will appeal the decision to the Supreme Court.

Notes to the consolidated financial statements (continued)

On October 1, 2013, SUNAT served Cerro Verde a demand for payment totaling S/.492 million (approximately US$144 million based on December 31, 2015 exchange rates, including interest and penalties of US$85 million) based on the Tax Tribunal’s decisions for the period December 2006 to December 2008. As permitted by law, Cerro Verde requested, and was granted, an installment payment program that deferred payment for six months and thereafter satisfies the amount via 66 equal monthly payments. As of December 31, 2015, Cerro Verde has made payments totaling S/219 million (equivalent to US$64 million) under the installment program. Based on the results rendered by the Eighteenth Contentious Administrative Court as is described in the previous paragraph, Cerro Verde requested an injunction that was accepted by the Judiciary and implied a modification of the installment program excluding the 2008 portion through SUNAT’s resolution notified to Cerro Verde on October 29, 2015.

In July 2013, a hearing on SUNAT's assessment for 2009 was held, but no decision has been issued by the Tax Tribunal for that year. As of December 31, 2015, the amount of the assessment, including interest and penalties, for the year 2009 was S/247 million (approximately US$72 million based on December 31, 2015, exchange rates). As of December 31, 2015, Cerro Verde estimates that the total exposure associated with mining royalties for the period from December 2006 to December 2013, including accumulated interest and penalties, amounted to approximately US$500 million at December 31, 2015 exchange rates.

As of December 31, 2015, no amounts were accrued for these assessments or for the amounts paid under the installment payment program because management and its external legal advisors believe Cerro Verde’s 1998 stability agreement exempted it from these royalties and believes that the resolution will be favorable to Cerro Verde and any payments should be recoverable.

| - | Other taxes

Cerro Verde has also received assessments from SUNAT for additional taxes (other than the mining royalty explained above), including penalties and interest. Cerro Verde has filed or will file objections to the assessments because it believes it has properly determined and paid its taxes. A summary of these assessments follows:

Fiscal Year |  | Taxes |  |  | Interest and fines |  |  | Total |
|  | US$(000) |  |  | US$(000) |  |  | US$(000) |
2002 – 2005 |  |  | 16,037 |  |  |  | 52,800 |  |  |  | 68,837 |
2006 |  |  | 6,545 |  |  |  | 47,662 |  |  |  | 54,207 |
2007 |  |  | 12,376 |  |  |  | 17,809 |  |  |  | 30,185 |

2010 |  |  | 65,997 |  |  |  | 89,404 |  |  |  | 155,401 |

2015 |  |  | 3,753 |  |  |  | - |  |  |  | 3,753 |
|  |  | 187,215 |  |  |  | 268,362 |  |  |  | 455,577 |

As of December 31, 2015, Cerro Verde has paid US$180,741,000 on these disputed tax assessments, which it believes is collectible.

Yanacocha -

| - | SUNAT challenged the withholding tax rate applied on the technical assistance services provided by non-resident supplier. The services were executed in Peru and also abroad; however, Yanacocha was not able to prove it during the tax audit. Based on that, SUNAT considers that the services were wholly executed in Peru; hence, the withholding tax rate must be 30% instead of 12%. The amount of the contingency involved is S/ 12.4 million (US$ 3.6 million). In Management's and its legal counsel’s opinion, that interpretation has no support so Yanacocha should get a favorable outcome in the appeal initiated.

| F-80 |

Notes to the consolidated financial statements (continued)

| - | SUNAT considers that the bonus for closing the collective agreement and the collateral benefits granted to the unionized and non-unionized employees qualify as remunerative concepts; hence, taxed with the contribution to ESSALUD. The contingency amounts to S/ 6.5 million (US$ 2 million).

In Management's and its legal counsel’s opinion, that interpretation has no support so Yanacocha should get a favorable outcome in the appeal initiated against the tax authorities.

Notes to the consolidated financial statements (continued)

| 31. | Disclosure of information on segments

Management has determined its operating segments based on reports that the Group’s Chief Operating Decision Maker (CODM) uses for making decisions. The Group is organized into business units based on its products and services, activities and geographic locations. The broad categories of the Group’s business units are:

| - | Production and sale of minerals;

| - | Exploration and development activities;

| - | Construction and engineering services;

| - | Energy generation and transmission services;

| - | Insurance brokerage;

| - | Rental of mining concessions;

| - | Holding of investment in shares (mainly in the associate company Minera Yanacocha S.R.L. and the Group’s subsidiary; S.M.R.L. Chaupiloma Dos de Cajamarca);

| - | Industrial activities.

The CODM monitors the operating results of the business units separately for the purpose of making decisions about resource allocation and performance assessment. Segment performance is evaluated based on operating profit or loss and is measured consistently with operating profit or loss in the Group’s consolidated financial statements. Also, the Group’s financing and income taxes are managed at the corporate level and are not allocated to the operating segments, except for those entities which are managed independently.

Corporate information mainly includes the following:

In segment information of profit and loss –

| - | Sales to third parties of gold purchased by the Parent company from La Zanja mining unit and the corresponding cost of sale as well as other intercompany sales;

| - | Administrative expenses, other income (expenses), exchange gain (loss), finance costs and income and income tax that cannot be directly allocated to the operational mining units owned by the Parent company (Uchucchacua, Orcopampa, Julcani, Mallay and Breapampa);

| - | Exploration activities in non-operating areas, carried out directly by the Parent company and not by the consolidated separate legal entities;

| - | Participation in subsidiaries and associate companies of the Parent company, which are accounted for using the equity method;

| - | Gain on business combination occurred in 2014, see Note 5 to the consolidated financial statements.

In the segment information of assets and liabilities –

| F-84 |

Notes to the consolidated financial statements (continued)

| - | Assets and liabilities of the operational mining units owned directly by the Parent company since this is the way the CODM analyzes the business. Assets and liabilities of other operating segments are allocated based on the assets and liabilities of the legal entities included in those segments.

Adjustments and eliminations mainly include the following:

In segment information of consolidated statements of profit and loss –

| - | The elimination of any profit or loss of investments accounted for under the equity method and not consolidated by the Group corresponding to the associate companies: Minera Yanacocha S.R.L., Sociedad Minera Cerro Verde S.A.A. and Compañía Minera Coimolache S.A.;

| - | The elimination of intercompany sales and cost of sales;

| - | The elimination of any equity pickup profit or loss of the subsidiaries of the Parent company.

Notes to the consolidated financial statements (continued)

| 32. | Derivative financial instruments

| (a) | The volatility of copper prices during the last years has caused the management of the subsidiary El Brocal to enter into future contracts. These contracts are intended to reduce the volatility of the cash flows attributable to the fluctuations in the cooper price, according to the risk strategy approved by the Board of Directors of this subsidiary. Based on this strategy, no more than 50% of existing sales commitments of copper concentrate are under future contracts.

As of December 31, 2015, El Brocal does not have open forward contracts (an asset of US$3,688,000 as of December 31, 2014, which balancing entry, net of the deferred income tax, amounted to a positive balance of US$2,485,000 and is presented in the “other reserves” caption of equity).

| (b) | Embedded derivative of commercial contracts -

The Group’s sales of concentrates are based on commercial contracts, under which a provisional sales value is determined based on future quotations (forward). The adjustment to sales is considered an embedded derivative, which is required to be separated from the host contract. Commercial contracts are linked to market prices (London Metal Exchange) at the dates of the expected settlements of the open positions as of December 31, 2015 and 2014. The embedded derivative does not qualify for hedge accounting; therefore, changes in the fair value are recorded as an adjustment to net sales.

Embedded derivatives held by the Group as of December 31, 2015 are:

| (c) | Hedge of the risk of fluctuation of foreign exchange rates

During 2015, the volatility of the foreign exchange rate between the Soles and the U.S. dollars, which is the functional and reporting currency of Buenaventura and El Brocal, has driven the Group’s Management to undertake hedge contracts of foreign currency exposure over their bank loans mentioned in Note 14. Buenaventura and El Brocal have signed forwards hedging contracts, which have been designated as hedging derivative cash flow because they are intended to cover the risk of fluctuations in the exchange rates of the financial obligations in soles.

Key deadlines of the hedging contract have been negotiated to match the terms and amounts of their obligations.

As of December 31, 2015, fair value of these hedge derivate financial instruments over exchange rates of current bank loans is a liability of US$10,643,000 and the effectiveness of these contracts has not been observed since it has not arisen any significant element of ineffectiveness.

| 33. | Financial - risk management objectives and policies

The Group’s principal financial liabilities, other than derivatives, comprise of trade accounts and other payables, and financial obligations. The main purpose of these financial instruments is to finance the Group’s operations. The Group’s principal financial assets include cash and cash equivalents and trade and other receivables that derive directly from its operations.

The Group is exposed to market risk, credit risk and liquidity risk. The Group’s Management oversees the management of these risks. It is supported by a committee that advises on financial risks. This committee provides assurance to management that the Group's financial risk activities are governed by appropriate policies and procedures and that financial risks are identified, measured and managed in accordance with the Group’s policies and risk objectives. All derivative activities for risk management purpose are carried out by internal specialists that have the appropriate skills, experience and supervision.

There were no changes in the objectives, policies or processes during the years ended December 31, 2015 and 2014.

The Board of Directors reviews and agrees policies for managing each of these risks, which are described below:

| (a) | Market risk -

Market risk is the risk that the fair value of the future cash flows from financial instruments will fluctuate because of changes in market prices. Market risks that apply to the Group comprise three types of risk: exchange rate risk, commodity risk and interest rate risk. Financial instruments affected by market risks include time deposits, financial obligations, embedded derivatives and derivative financial instruments.

Notes to the consolidated financial statements (continued)

The sensitivity analyses in this section relate to the positions as of December 31, 2015, 2014 and 2013, and have been prepared considering that the proportion of financial instruments in foreign currency are constant.

| (a.1) | Exchange rate risk

The exchange rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. The Group’s exposure to the risk of changes in foreign exchange relates primarily to the Group´s operating activities in Soles. The Group mitigates the effect of exposure to exchange-rate risk by carrying out almost all of its transactions in its functional currency.

On the other hand, the Group has contracted hedges exchange rate to mitigate this risk on their loans obtained in soles. Excluding loans in soles, Management maintains smaller amounts in Soles in order to cover its needs in this currency (primarily taxes).

| F-93 |

Notes to the consolidated financial statements (continued)

A table showing the effect on results of a reasonable change in foreign-currency exchange rates is presented below, with all other variables kept constant:

|  | Exchange-rate increase/decrease |  |  | Effect on loss before income tax |
|  |  |  |  | US$(000) |
2015 |  |  |  |  |  |
Exchange rate |  |  | +10 | % |  |  | 6,233 |
Exchange rate |  |  | -10 | % |  |  | (7,618 | )
2014 |  |  |  |  |  |  |  |
Exchange rate |  |  | +10 | % |  |  | 5,950 |
Exchange rate |  |  | -10 | % |  |  | (7,271 | )
2013 |  |  |  |  |  |  |  |
Exchange rate |  |  | +10 | % |  |  | 20,989 |
Exchange rate |  |  | -10 | % |  |  | (25,225 | )

| (a.2) | Commodity price risk

The Group is affected by the price volatility of the commodities. The price of mineral sold by the Group has fluctuated historically and is affected by numerous factors beyond its control. The Group manages its commodity price risk primarily through the use of sales commitments in customer contracts and hedge contracts for the metals sold by the subsidiary El Brocal.

The subsidiary El Brocal entered into derivative contracts that qualified as cash flow hedges, with the intention of covering the risk resulting from the fall in the prices of the metals. These derivative contracts are recorded as assets or liabilities in the statements of financial position and are stated at fair value. To the extent that these hedges were effective in offsetting future cash flows from the sale of the related production, changes in fair value are deferred in an equity account. The deferred amounts were reclassified to the appropriate sales when production was sold.

| (a.3) | Interest rate risk -

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Group’s exposure to the risk of changes’ in market interest rates relates to the Groups’ long-term financial obligations with floating interest rates.

Interest rate |  |  | +10 |  |  |  | 58 |
Interest rate |  |  | -10 |  |  |  | (58 | )

| (b) | Credit risk -

Credit risk is the risk that counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. The Group is exposed to credit risk from its operating activities (primarily trade receivable) and from its financing activities, including deposits with banks and other financial instruments.

The Group invests the excess cash in financial leading institutions, sets conservative credit policies and constantly evaluates the market conditions in which it operates.

Trade accounts receivable are denominated in U.S. dollars. The Group’s sales are made to domestic and foreign customers. See concentration of spot sales in Note 21(b). An impairment analysis is performed on an individual basis.

Credit risk is limited to the carrying amount of the financial assets to the date of consolidated statements of financial position which is composed by cash and cash equivalents, trade and other receivables and derivative financial instruments.

| (c) | Liquidity risk -

Prudent management of liquidity risk implies maintaining sufficient cash and cash equivalents and the possibility of committing or having financing committed through an adequate number of credit sources. The Group maintains suitable levels of cash and cash equivalents and has sufficient credit capacity to get access to lines of credit in leading financial entities.

The Group continually monitors its liquidity risk based on cash flow projections.

Financial assets at fair value with changes in profit or loss |  |  | 3,688 |  |  |  | - |  |  |  | 3,688 |  |  |  | - |
Liabilities measured at fair value: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

- Contingent consideration liability |  |  | 23,026 |  |  |  | - |  |  |  | - |  |  |  | 23,026 |

Financial instruments whose fair value is similar to their book value -

For financial assets and liabilities such as cash and cash equivalents, trade and other receivables, trade and other payables that are liquid or have short-term maturities (less than three months), it is estimated that their book value is similar to their fair value. The derivatives are also recorded at the fair value so that differences do not need to be reported.

The fair value of embedded derivatives is determined using valuation techniques with information directly observable in the market (future metal quotations).

Financial instruments at fixed and variable rates -

The fair value of financial assets and liabilities at fixed and variable rates at amortized cost is determined by comparing the market interest rates at the time of their initial recognition to the current market rates with regard to similar financial instruments. The estimated fair value of deposits that accrue interest is determined by means of cash flows discounted using the prevailing market interest rates in the currency with similar maturities and credit risks.

Based on the foregoing, there are no important existing difference between the value in books and the reasonable value of the assets and financial liabilities as of December 31, 2015 and 2014.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company´s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis of designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company´s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.

Minera Yanacocha S.R.L. and Subsidiary

Notes to the consolidated financial statements

For the years 2015, 2014 and 2013

| 1. | Identification and business activities of the Company

| (a) | Identification -

Minera Yanacocha S.R.L. hereinafter “the Company”, was incorporated in Peru on January 14, 1992 and commenced operations in 1993. The Company is engaged in the production of gold and exploration and development of gold and copper under the mining concessions it owns or that are owned by S.M.R.L. Chaupiloma Dos de Cajamarca ("Chaupiloma").

The Company is 51.35% owned by Newmont Second Capital Corporation, a 100% indirectly owned subsidiary of Newmont Mining Corporation ("Newmont", the ultimate Parent company), 43.65% owned by Compañia Minera Condesa S.A., which is 100% owned by Compañia de Minas Buenaventura S.A.A. (“Buenaventura”) and 5% owned by the International Finance Corporation.

The majority Partners of the Company (or their affiliates) also own the majority interest in Chaupiloma. In accordance with a mining lease, amended and effective on January 1, 1994, the Company pays Chaupiloma a 3% royalty based on quarterly production soId at current market prices, after deducting refinery and transportation costs. The royalty agreement expires in 2032.

| (b) | Business activities-

The Company's operations are located near Cajamarca, province of Peru and currently include the following open pit mines: Chaquicocha, Maqui Maqui, Cerro Yanacocha, La Quinua Complex (La Quinua, El Tapado, El Tapado Oeste), Cerro Negro Este, Wester Oxide pits (La Quinua Sur and Cerro Negro Oeste), Eastern Oxide pits (Quecher Norte and Marleny) and Carachugo Alto. The Company has four leach pads, three processing facilities, and one mill. Gold-bearing ores are transported to one of four leach pads for gold recovery using conventional heap-leaching or milling, followed by Merrill - Crowe zinc precipitation and smelting where a final doré product is poured. The doré is then shipped offsite for refining and is sold on the worldwide gold markets.

Gold mining requires the use of specialized facilities and technology. The Company relies heavily on such facilities and technology to maintain production levels. Also, the cash flows and profitability of the Company's operations are significantly affected by the market price of gold. Gold prices can fluctuate widely and are affected by numerous factors beyond the Company's control. During 2015, 2014 and 2013, the Company produced 0.92 million, 0.97 million and 1.02 million ounces of gold, respectively.

Conga project

The Conga Project consists of two gold-copper porphyry deposits located northeast of the Yanacocha operating area in the provinces of Celendin, Cajamarca and Hualgayoc. There is no exploration and/or development of new reserves as development of the project's development and reserve balances reported for Conga in 2014 were reclassified to mineralized material in 2015.

| F-107 |

Notes to the consolidated financial statements (continued)

As a result of local political and community protests, construction and development activities at the Conga project were largely suspended in November 2011. The results of the Peruvian Central Government’s initiated Environmental Impact Assessment (“EIA”) independent review were reported on April 20, 2012. The review indicated the project’s EIA met Peruvian and International Standards. The review made recommendations to provide additional water capacity and social funds, which Yanacocha has largely accepted. Yanacocha announced the decision to move the project forward on a “water-first” approach on June 22, 2012. In the first half of 2014, a Conga Restart Study was completed to identify and test alternatives to advancing development of the project. Following this assessment, a new plan was developed to reduce spending to focus on only the most critical work – protecting people and assets, engaging with communities, and maintaining existing project infrastructure – while maintaining optionality. Newmont will not proceed with the full development of Conga without social acceptance, solid project economics and potentially another partner to help defray costs and risk; it is currently difficult to predict when or whether such events may occur. Under the current social and political environment, the Company does not anticipate being able to develop Conga for the foreseeable future. The continued delay and evaluation of other alternatives may result in a potential accounting impairment or further reclassification of Mineralized Material.

| (c) | Approval of consolidated financial statements -

The consolidated financial statements as of December 31, 2015 were approved by the Company’s Management on February 25, 2016 and, in its opinion, will be approved without changes at the Partners’ Meeting to be held within the terms established by Law.

The consolidated financial statements as of December 31, 2014 and 2013 were issued with the approval of the Partners’ Meeting held on March 26, 2015.

| 2. | Basis for preparation, consolidation and accounting policies

| 2.1. | Basis of preparation -

The consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standard Board (“ASB”) and interpretations issued by the IFRS Interpretations Committee (“IFRIC”). The consolidated financial statements have been prepared under the historical cost basis, except for available-for-sale financial assets which are measured at their fair value.

The consolidated financial statements are presented in U.S. dollars and all values are rounded to the nearest thousands, except when otherwise indicated.

The preparation of consolidated financial statements requires that Management use judgments, estimates and assumptions, as detailed in Note 3.

These consolidated financial statements provide comparative information in respect of prior periods.

| F-108 |

Notes to the consolidated financial statements (continued)

| 2.2. | Basis of consolidation -

The consolidated financial statements comprise the financial statements of the Company and its subsidiary (San Jose Reservoir Trust, a separate legal entity created to ensure the continuity of the Company’s operations in the San Jose Reservoir after 2018).

Control is achieved when the Company is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Company controls an investee if, and only if, the Company has:

| - | Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee);

| - | Exposure, or rights, to variable returns from its involvement with the investee;

| - | The ability to use its power over the investee to affect its returns.

Generally, there is a presumption that a majority of voting rights result in control. To support this presumption and when the Company has less than a majority of the voting or similar rights of an investee, the Company considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

| - | The contractual arrangement with the other vote holders of the investee.

| - | Rights arising from other contractual arrangements.

| - | The Company’s voting rights and potential voting rights or a combination of rights.

The Company re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Company gains control until the date the Company ceases to control the subsidiary.

When necessary, adjustments are made to the financial statements of the subsidiary to bring its accounting policies into line with the Company’s accounting policies.

All intra-group assets and liabilities, equity, income, expenses and cash flows are eliminated in full on consolidation.

A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction.

| F-109 |

Notes to the consolidated financial statements (continued)

| 2.3. | Changes in accounting policies and disclosures -

Certain standards and amendments are effective for annual periods beginning on or after January 1, 2015. However, they do not impact the annual consolidated financial statements of the Company and, hence, have not been disclosed. The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

| 2.4. | Summary of significant accounting policies and practices -

| (a) | Foreign currencies -

The consolidated financial statements are stated in U.S. dollars, the Company's functional currency. Transactions in other currencies are recorded in U.S. dollars based on exchange rates prevailing at the time of such transactions. Monetary assets and liabilities denominated in other currencies are translated into the U.S. dollar at exchange rates prevailing at the statements of financial position dates, and any resulting gains or losses are reflected in current earnings.

| (b) | Financial instruments - Initial recognition and subsequent measurement -

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

| (i) | Financial assets -

Initial recognition and measurement -

Financial assets are classified, at initial recognition, as financial assets at fair value through profit or loss, loans and receivables, held-to-maturity investments, available-for-sale financial assets, or derivatives designated as hedging instruments in an effective hedge, as appropriate. All financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit or loss, transaction costs that are attributable to the acquisition of the financial asset.

Subsequent measurement -

For purposes of subsequent measurement, financial assets are classified in four categories:

| - | Financial assets at fair value through profit or loss.

| - | Loans and receivables.

| - | Held-to-maturity investments.

| - | Available-for-sale financial investments.

Financial assets at fair value through profit or loss -

Financial assets at fair value through profit or loss include financial assets held for trading and financial assets designated upon initial recognition at fair value through profit or loss. Financial assets are classified as held for trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments as defined by IAS 39.

| F-110 |

Notes to the consolidated financial statements (continued)

Financial assets at fair value through profit or loss are carried in the consolidated statements of financial position at fair value with net changes in fair value presented as finance costs (negative changes) or finance revenue (positive changes) in the consolidated statements of comprehensive income.

Derivatives embedded in host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value though profit or loss. These embedded derivatives are measured at fair value, with changes in fair value recognized in profit or loss.

Loans and receivables -

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate method, less impairment. The losses arising from impairment are recognized in the consolidated statements of profit or loss.

This category generally applies to trade and other receivables, net.

Held-to-maturity investments -

Non-derivative financial assets with fixed or determinable payments and fixed maturities are classified as held to maturity when the Company has the positive intention and ability to hold them to maturity. The Company did not have any held-to-maturity investments as of December 31, 2015 and 2014.

Available-for-sale financial assets -

The available-for-sale financial assets include equity investments and debt securities. Equity investments classified as available-for-sale are those that are neither classified as held for trading nor designated at fair value through profit or loss. Debt securities in this category are those that are intended to be held for an indefinite period of time and may be sold in response to needs for liquidity, or in response to changes in the market conditions (Note 9).

Derecognition -

A financial asset (or, where applicable a part of a financial asset or part of a group of similar financial assets) is primarily derecognized when:

| - | The rights to receive cash flows from the asset have expired.

| - | The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a pass-through arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset or, (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset, or has entered into a pass-through arrangement, it evaluates if and to what extent, it has retained the risk and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company’s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

| F-111 |

Notes to the consolidated financial statements (continued)

Impairment of financial assets -

The Company assesses, at each reporting date, whether there is objective evidence that a financial asset or group of financial assets is impaired. An impairment exists if one or more events that has occurred since the initial recognition of the asset (an incurred "loss event") has an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated.

Evidence of impairment may include indications that the debtors or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization and observable data indicating that there is a measurable decrease in the estimated future cash flows, such as changes in economic conditions that correlate with defaults.

For financial assets carried at amortized cost, the Company first assesses whether impairment exists for financial assets that are individually significant, or collectively for financial assets that are individually insignificant.

The amount of any impairment loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows. The present value of the estimated future cash flows is discounted at the financial asset’s original effective interest rate.

The carrying amount of the asset is reduced through the use of an allowance account and the loss is recognized in the consolidated statements of comprehensive income. Interest income (recorded as revenue in the statements of comprehensive income) continues to be accrued on the reduced carrying amount and is accrued using the interest rate used to discount the future cash flows for the purpose of measuring the impairment loss. Loans, together with the associated allowance, are written off when there is no realistic prospect of a future recovery and all collateral has been realized or has been transferred to the Company. If, in a subsequent year, the amount of the estimated impairment loss increases or decreases due to an event occurring after the impairment was recognized, the previously recognized impairment loss is increased or reduced by adjusting the allowance account. If a write-off is later recovered, the recovery is credited to finance costs in the consolidated statements of comprehensive income.

| (ii) | Financial liabilities –

Initial recognition and measurement -

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, accounts payable, financial obligations, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of interest-bearing loans and borrowings and payables, net of directly attributable transaction costs.

| F-112 |

Notes to the consolidated financial statements (continued)

The Company’s financial liabilities include trade and other payables.

Subsequent measurement -

The measurement of financial liabilities depends on their classification. Trade and other payables are subsequently measured at amortized cost.

Derecognition -

A financial liability is derecognized when the obligation under the liability is discharged, cancelled or expires.

When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the consolidated statements of comprehensive income.

| (iii) | Offsetting of financial instruments -

Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statements of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

| (c) | Cash and cash equivalents -

Cash and cash equivalents include cash in hand, deposits held at call with banks and other short-term highly liquid investments with original maturities of three months or less. Restricted cash is excluded from cash and cash equivalents and is included in other current assets or long-term assets depending on restrictions.

| F-113 |

Notes to the consolidated financial statements (continued)

| (d) | Stockpiles, ore on leach pads and inventories -

Costs that are incurred in or benefit the productive process are accumulated as stockpiles, ore on leach pads and inventories. Stockpiles, ore on leach pads and inventories are carried at the lower of average cost or net realizable value. Net realizable value represents the estimated future sales price of the product based on current and long-term metals prices, less the estimated costs to complete production and bring the product to sale. Write-downs of stockpiles, ore on leach pads and inventories to net realizable value are reported as a component of costs applicable to sales. The current portion of stockpiles, ore on leach pads and inventories is determined based on the expected amounts to be processed within the next twelve months. Stockpiles, ore on leach pads and inventories not expected to be processed within the next twelve months are classified as non-current. The major classifications are as follows:

| (i) | Stockpiles -

Stockpiles represent ore that has been extracted from the mine and is available for further processing. Stockpiles are measured by estimating the number of tons added and removed from the stockpile, the number of contained ounces (based on assay data) and the estimated metallurgical recovery rates (based on the expected processing method). Stockpile ore tonnages are verified by periodic surveys. Costs are allocated to stockpiles based on relative values of material stockpiled and processed using current mining costs incurred up to the point of stockpiling the ore, including applicable overhead and depreciation and amortization relating to mining operations, and removed at each stockpile's average cost per recoverable unit as material is processed.

| (ii) | Ore on leach pads -

The recovery of gold from certain gold oxide ores is achieved through the heap leaching process. Under this method, oxide ore is placed on leach pads where it is treated with a chemical solution, which dissolves the gold contained in the ore. The resulting gold-bearing solution is later processed in a plant where the gold is recovered. Costs are added to ore on leach pads based on current mining costs, including applicable overhead and depreciation and amortization relating to mining operations. Costs are removed from ore on leach pads as ounces are recovered based on the average cost per estimated recoverable ounce of gold on the leach pad.

The estimates of recoverable gold on the leach pads are calculated from the quantities of ore placed on the pads (measured tons added to the leach pads), the grade of ore placed on the leach pads (based on assay data) and a recovery percentage (based on ore type). In general, the leach pads recover between 50% and 95% of the ultimate recoverable ounces in the first year of leaching, declining each year thereafter until the leaching process is complete.

| F-114 |

Notes to the consolidated financial statements (continued)

Although the quantities of recoverable gold placed on the leach pads are reconciled by comparing the grades of ore placed on the pads to the quantities of gold actually recovered (metallurgical balancing), the nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, the metallurgical balancing process is constantly monitored and estimates are refined based on actual results over time. Historically, the Company's operating results have not been materially impacted by variations between the estimated and actual recoverable quantities of gold on its leach pads. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted for on a prospective basis.

| (iii) | In-process inventory -

In-process inventories represent materials that are currently in the process of being converted to a saleable product. Conversion processes vary depending on the nature of the ore and the specific processing facility, and include mill in-circuit and leach in-circuit. In-process material is measured based on assays of the material fed into the process and the projected recoveries of the respective plants. In-process inventories are valued at the average cost of the material fed into the process attributable to the source material coming from the mines, stockpiles and/or leach pads plus the in- process conversion costs, including applicable amortization relating to the process facilities incurred to that point in the process.

| (iv) | Precious metals inventory -

Precious metals include gold Doré and/or gold bullion. Precious metals that result from the Company's mining, processing activities are valued at the average cost of the respective in-process inventories incurred prior to the refining process, plus applicable refining costs.

| (v) | Materials and supplies -

Materials and supplies are valued at the lower of average cost or replacement value. Cost includes applicable taxes and freight.

| (e) | Property, plant and equipment -

The cost of an element of property, plant and equipment comprises the following: the acquisition price or manufacturing cost, including non-reimbursable customs and taxes and any cost necessary to place the asset in operating condition, as anticipated by Management; the initial estimate of the rehabilitation obligation and; in the case of qualified assets, the financing costs.

The purchase price or construction cost corresponds to the total amount paid and fair value of any other consideration provided to acquire the asset. Subsequent costs attributable to property, plant and equipment are capitalized only when it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably, otherwise the cost is charged to production or expense.

Maintenance and repair expenses are charged to the production cost or expense, as necessary, in the period when incurred.

| F-115 |

Notes to the consolidated financial statements (continued)

Expenses incurred to replace a component of an item or element of property, plant and equipment are capitalized separately, writing-off the carrying amount of the component being replaced. In the event the component replaced has not been considered as a separate component of the asset item, the replacement value of the new component is used to estimate the carrying amount of the assets being replaced.

Assets in the construction stage are capitalized as separate components. At their completion, the cost is transferred to the appropriate category. Work in progress is not depreciated.

Depreciation

Land is not depreciated. Other than land, depreciation of property, plant and equipment is calculated using the straight-line method to allocate their cost less their residual value over their estimated useful lives and in the case of assets assigned to the production process of Yanacocha, under the lower of that determined under the units of production method or the useful life of the mine, as follows:

| Years
Land improvements | 25 years
Buildings | Between 5 and 25 years
Plant and equipment | Between 3 and 15 years
Vehicles | Between 3 and 5 years
Furniture and fittings | Between 3 and 10 years
Other equipment | Between 3 and 10 years
Computer equipment | Between 3 and 8 years
Assets retirement cost | Useful life of the mine and/or process facilities

The assets' useful lives and residual values are reviewed, and adjusted if appropriate, at each date of the consolidated statement of financial position. Any changes in these estimates are prospectively adjusted.

Disposal of assets

Property, plant and equipment items are written-off at the date they are sold or when no economic benefits are expected from their further use or sale. Gains and losses on disposals of assets are determined by comparing the proceeds with their carrying amounts. These gains or losses are included in the consolidated statements of comprehensive income.

| F-116 |

Notes to the consolidated financial statements (continued)

| (f) | Mineral Interests -

Mineral interests include acquired interests in production, development and exploration stage properties. The mineral interests are capitalized at their fair value at the acquisition date.

The value of such assets is primarily driven by the nature and amount of mineralized material believed to be contained in such properties. Production stage mineral interests represent interests in operating properties that contain proven and probable reserves. Development stage mineral interests represent interests in properties under development that contain proven and probable reserves.

Exploration stage mineral interests represent interests in properties that are believed to potentially contain mineralized material consisting of (i) mineralized material such as inferred material within pits; mineralized material with insufficient drill spacing to qualify as proven and probable reserves; and mineralized material in close proximity to proven and probable reserves; (ii) around-mine exploration potential not immediately adjacent to existing reserves and mineralization, but located within the immediate mine area; (iii) other mine-related exploration potential that is not part of current mineralized material and is comprised mainly of material outside of the immediate mine area; (iv) greenfield exploration potential that is not associated with any other production, development or exploration stage property, as described above; or (v) any acquired right to explore or extract a potential mineral deposit.

Exploration costs are capitalized when reserves at the location are declared in the Reserves and Resource information published annually by Newmont in its form 10-K. At this point, exploration costs are capitalized as mine development or as a component of property, plant and equipment, as appropriate.

The Company's mineral rights generally are enforceable regardless of whether proven and probable reserves have been established. The Company has the ability and intent to renew mineral interests where the existing term is not sufficient to recover all identified and valued proven and probable reserves and/or undeveloped mineralized material.

Mineral interests are presented in the caption of property, plant and equipment.

| (g) | Mine development -

Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, and the removal of overburden to initially expose an ore body at open pit surface mines. Costs incurred before mineralization is classified as proven and probable reserves are expensed and classified as Exploration or Advanced projects, research and development expense. Capitalization of mine development project costs, that meet the definition of an asset, begins once mineralization is classified as proven and probable reserves.

| F-117 |

Notes to the consolidated financial statements (continued)

Drilling and related costs are capitalized for an ore body where proven and probable reserves exist; and the activities are directed at obtaining additional information on the ore body or converting mineralized material to proven and probable reserves. AII other drilling and related costs are expensed as incurred. Drilling costs incurred during the production phase for operational ore control are allocated to inventory costs and then included as a component of Costs applicable to sales.

The cost of removing overburden and waste materials to access the ore body at an open-pit mine prior to the production phase are referred to as "pre-stripping costs." Pre-stripping costs are capitalized during the development of an open-pit mine. Where multiple open pits exist at a mining complex utilizing common processing facilities, pre-stripping costs are capitalized at each pit. The removal and production of de minimis saleable materials may occur during development and are recorded as Other income, net of incremental mining and processing costs. See (h) below.

Mine development costs are amortized using the units-of production ("UOP") method based on estimated recoverable ounces in proven and probable reserves. To the extent that these costs benefit an entire ore body, they are amortized over the estimated life of the ore body. Costs incurred to access specific ore blocks or areas that only provide benefit over the life of that area are amortized over the estimated life of that specific ore block or area.

Mine development costs are presented in the caption of Property, plant and equipment, net.

| (h) | Stripping activity asset -

The Company accounts for stripping costs incurred during the production phase of a surface mining in accordance with IFRIC 20 "Stripping costs in the production phase of as surface mine" whereby a stripping asset is recognized if, and only if, all of the following are met:

| - | It is probable that the future economic benefit (improved access to the ore body) associated with the stripping activity will flow to the entity;

| - | The entity can identify the component of the ore body for which access has been improved; and

| - | The costs relating to the stripping activity associated with that component can be measured reliably.

The primary components of the ore body on a pit by pit basis as well as within major pits are identified. Based on these components, stripping activities are analyzed and costs are assigned based on whether they pertained to current inventory production or improved access to future ore bodies (or components of an ore body).

Based on this analysis, the Company allocated the costs associated with improved access as a production stripping asset. This allocation is based on the volume of waste and ore extracted in the period compared to expected volume life-of-mine per component of ore body.

Costs allocated to the production stripping activity asset are subsequently depreciated. Depreciation of the production stripping asset was calculated on a systematic basis ("waste-to-ore tons ratio") method over the expected useful life of the identified component of the ore body that becomes more accessible as a result of the stripping costs. This depreciation is a production cost.

| (i) | Impairment of non-financial assets -

The carrying amounts of non-financial assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. If there are indicators of impairment, a review is undertaken to determine whether the carrying values are in excess of the recoverable amount. The recoverable amount is determined as the higher of an asset's fair value, less costs of disposal, and its value in use. Such review is undertaken on an asset by asset basis, except where such assets do not generate cash flows independently from other assets, in which case the review is undertaken at the cash generating unit level. The Company identified two separate cash generating units according to its segments; Yanacocha and Conga.

Future cash flows are estimated based on quantities of recoverable minerals, expected gold and other commodity prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans and the appropriate discount rate. These estimates, used in the determination of future cash flows, are based on numerous assumptions and it is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of recoverable minerals, gold and other commodity prices, production levels, costs and capital and interest rates are each subject to significant risks and uncertainties.

If the carrying amount of an asset exceeds its recoverable amount, an impairment loss is recorded in the statement of comprehensive income to reflect the asset at the lower amount. In assessing the recoverable amount for assets, the relevant future cash flows expected to arise from the fair value less costs of disposal have been discounted to their present value.

An impairment loss is reversed in the statement of comprehensive income if there is a change in estimate used to determine recoverable amount since the prior impairment loss was recognized.

The carrying amount of an asset is increased to the recoverable amount but not beyond the carrying amount net of depreciation or amortization which would have arisen if the prior impairment loss had not been recognized. After such a reversal the depreciation charge is adjusted in future periods to allocate the asset's revised carrying amount, less any residual value, on a systematic basis over its remaining useful life.

| (j) | Provisions -

General-

Provisions are recognized when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount has been reliably estimated. If the time value of money is significant, provisions are discounted using pre-tax rates, which reflect, when appropriate, the liabilities' specific risks. The reversal of the discount due to the passage of time originates the increase of the obligation which is recognized with a charge to the statement of comprehensive income as a finance cost.

Provisions are reviewed periodically and are adjusted to reflect the best estimate available as of the date of the consolidation statement of financial position. The expenses related to other provisions are presented in the consolidated statement of comprehensive income.

Disclosure of contingent obligations is provided when their existence will only be confirmed by future events or their amount cannot be reliably measured. Contingent assets are not recognized and are disclosed only if it is probable that the Company will generate future economic benefits.

| F-119 |

Notes to the consolidated financial statements (continued)

Asset Retirement Obligation -

Reclamation obligations are recognized when incurred and recorded as liabilities at the best estimate of the expenditure required to settle the obligation. The liability is accreted over time through periodic charges to earnings. In addition, the asset retirement cost is capitalized as part of the asset's carrying value and amortized over the life of the related asset. Reclamation costs are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. The estimated reclamation obligation is based on when spending for an existing disturbance is expected to occur. The Company reviews, on an annual basis, unless otherwise deemed necessary, the reclamation obligation at each mine site.

| F-120 |

Notes to the consolidated financial statements (continued)

| (k) | Revenue recognition -

Revenue from the sale of gold is recognized net of treatment and refining charges, when persuasive evidence of an arrangement exists, the price is determinable, the product has been delivered, risk and title has been transferred to the customer and collection of the sales price is reasonably assured.

Sales contracts for copper, silver and carbon incorporate provisional pricing at the date of delivery of the mineral ore. The final price is an average market price for a particular future period. Revenue from provisionally priced sales of copper, silver and carbon fine is recognized when risks and rewards of ownership are transferred to the customer, generally at the date of delivery, and revenue can be measured reliably. At this date, the amount of revenue to be recognized will be estimated based on the forward market price of the commodity being sold.

Revenues from silver and copper sales are credited to Costs applicable to sales as a by-product credit. Royalties paid based on revenue are charged to revenue.

| (l) | Taxes -

Current income tax -

Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from, or paid to, the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the reporting date in Peru.

Current income tax relating to items recognized directly in other comprehensive income or equity is recognized in other comprehensive income or equity and not in profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations where applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred income tax -

The Company accounts for income and mining taxes using the liability method, recognizing certain temporary differences between the financial reporting basis of the Company's liabilities and assets and the related income tax basis for such liabilities and assets. This method generates a net deferred income tax liability or net deferred income tax asset for the Company, as measured by the statutory tax rates in effect as enacted. The Company derives its deferred income tax charge or benefit by recording the change in the net deferred income tax liability or net deferred income tax asset balance for the year, based on Peruvian income and mining tax laws. Royalty taxes are calculated based on operating profit, as such are shown as income tax.

| F-121 |

Notes to the consolidated financial statements (continued)

The Company's deferred income tax assets include certain future tax benefits. The Company determines valuation allowance to any portion of those deferred income tax assets when it believes, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset will not be realized (Note 14).

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.

Sales tax -

Expenses and assets are recognized net of the amount of sales tax, except:

| (i) | When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable;

| (ii) | When receivables and payables are stated with the amount of sales tax included.

The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the consolidated statements of financial position.

| (m) | Fair value measurement -

The Company measures its financial instruments, such as, derivatives and embedded derivatives, at fair value as of the date of the consolidated statements of financial position.

Fair value is the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

| - | In the principal market for the asset or liability, or

| - | In the absence of a principal market, in the most advantageous market for the asset or liability.

| F-122 |

Notes to the consolidated financial statements (continued)

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described, as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

| - | Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities.

| - | Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable.

| - | Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For assets and liabilities that are recognized in the consolidated statements of financial position on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by reassessing categorization (based on the lowest-level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

The Company's Management determines the policies and procedures for both recurring fair value measurement and non-recurring measurement. At each reporting date, the Company's Management analyzes the movements in the values of assets and liabilities which are required to be re-measured or re-assessed as per the Company’s accounting policies.

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

| 3. | Significant judgments, estimates and assumptions

The preparation of the Company’s consolidated financial statements requires Management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. The estimates and assumptions are continuously evaluated and based on Management’s experience and other facts, including the expectations about future events which are reasonable under the current situation. Uncertainty about these estimates and assumptions could result in outcomes that require material adjustment to the carrying amount of assets and liabilities affected in future periods. Further information on each of these areas and how they impact the various accounting policies are described below and also in the relevant notes to the consolidated financial statements.

| F-123 |

Notes to the consolidated financial statements (continued)

| 3.1. | Judgments

In the process of applying the Company’s accounting policies, Management has made the following judgments, which have the most significant effect on the amounts recognized in the consolidated financial statements:

| (a) | Contingencies -

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential quantum of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

| (b) | Development start date -

The Company assesses the status of each exploration project to determine when the development phase begins. One of the criteria used to evaluate the development start date is when the Company determines that the property can be economically developed.

| (c) | Production start date -

The Company assesses the stage of each mine under development to determine when a mine moves into the production phase. The determination of the start date is based on the unique nature of each mining project; such as the complexity of the project and its location. The Company considers various relevant criteria to assess when the production phase is considered to have commenced. Some of the criteria used to identify the production start date include, but are not limited to:

| - | Level of capital expenditure incurred compared to the original construction cost estimates.

| - | Completion of a reasonable period of testing of the mine plant and equipment.

| - | Ability to produce metal in saleable form (within specifications).

| - | Ability to sustain ongoing production of metal.

When a mine development /construction project moves into the production phase, the capitalization of certain mine development costs ceases and costs are either regarded as forming part of the cost of inventory or expensed, except for costs that qualify for capitalization relating to mining asset additions or improvements. It is also at this point that depreciation or amortization commences.

| 3.2. | Estimates and assumptions

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Company based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market change or circumstances arising beyond the control of the Company. Such changes are reflected in the assumptions when they occur.

| F-124 |

Notes to the consolidated financial statements (continued)

| (a) | Determination of mineral reserves and resources -

The Company calculates its reserves using methods generally applied by mining and industry according to international guidelines. All estimated reserves represent estimated quantities of mineral proven and probable that under current conditions can be economically and legally processed.

The process of estimating quantities of reserves is complex and requires making subjective decisions when evaluating all geological, geophysical, engineering and economic information available. Reviews could occur on reserve estimates due to, among others, revisions to the data or geological assumptions, changes in prices, production costs and results of exploration activities. Changes in estimated reserves could affect the carrying value of mining concessions, development costs and property, plant and equipment, the charges in result for depreciation and amortization, and the carrying amount of the provision for closure of mining units.

| (b) | Units of production depreciation -

Estimated economically recoverable reserves are used in determining the depreciation and/or amortization of mine-specific assets. This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life-of-mine production. The life of each item, which is assessed at least annually, has regard to both its physical life limitations and present assessments of economically recoverable reserves of the mine property at which the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes in estimates are accounted for prospectively.

| (c) | Mine rehabilitation provision -

The Company assesses its mine rehabilitation provision at each reporting date. The ultimate rehabilitation costs are uncertain, and cost estimates can vary in response to many factors, including estimates of the extent and costs of rehabilitation activities, technological changes, regulatory changes, cost increases as compared to the inflation rates, and changes in discount rates. These uncertainties may result in future actual expenditure differing from the amounts currently provided. The provision at reporting date represents Management’s best estimate of the present value of the future rehabilitation costs required.

| (d) | Inventories, net -

Net realizable value tests are performed at each reporting date and represent the estimated future sales price of the product the entity expects to realize when the product is processed and sold, less estimated costs to complete production and bring the product to sale.

Stockpiles and ore on leach pads are measured by estimating the number of tons added and removed from the stockpile and leach pads, the number of contained gold ounces, assay data, and the estimated recovery percentage based on the expected processing method. Stockpile and ore on leach pad tonnages are verified by periodic surveys.

| F-125 |

Notes to the consolidated financial statements (continued)

| (e) | Impairment of non-financial assets -

The Company assesses each asset or cash generating unit in each reporting period to determine whether any indication of impairment exists. Where an indicator of impairment exists, a formal estimate of the recoverable amount is made, which is considered to be the higher of the fair value less costs of disposal and value in use. The assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates and operating costs, among others. These estimates and assumptions are subject to risk and uncertainty.

The fair value of mining assets is calculated by the present value of future cash flows arising from the continued use of the asset, which include some estimates, such as the cost of future expansion plans, using assumptions that a third party might consider. The future cash flows are discounted to their present value using a discount rate that reflects current market assessment of the value of money over time, as well as specific risks of the asset or cash-generating unit under evaluation.

The Company has determined the operations of Yanacocha and Conga as the cash generating units.

| (f) | Taxes -

Deferred tax assets are recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized. Significant Management judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits together with future tax planning strategies.

| 4. | Standards issued but not effective

The standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Company’s financial statements that the Company reasonably expects will have an impact on its disclosures, financial position or performance when applied at a future date are disclosed below. The Company intends to adopt these standards, if applicable, when they become effective. The Company has not listed other standards and interpretations that are issued, but not yet effective, as these are not expected to impact the Company.

IFRS 9 Financial Instruments

In July 2014, the IASB issued the final version of IFRS 9 Financial Instruments that replaces IAS 39 and all previous versions of IFRS 9. IFRS 9 brings together all three aspects of the accounting for financial instruments project: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for annual periods beginning on or after January 1, 2018, with early application permitted. Except for hedge accounting, retrospective application is required, but the provision of comparative information is not compulsory. For hedge accounting, the requirements are generally applied prospectively, with some limited exceptions.

| F-126 |

Notes to the consolidated financial statements (continued)

IFRS 15 Revenue from Contracts with Customers

IFRS 15 was issued in May 2014 and establishes a five-step model to account for revenue arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. The new revenue standard will supersede all current revenue recognition requirements under IFRS. Either a full retrospective application or a modified retrospective application is required for annual periods beginning on or after January 1, 2018. Early adoption is permitted.

Amendments to IFRS 10 and IAS 28: Sale or Contribution of Assets between an Investor and its Associate or Joint Venture

The amendments address the conflict between IFRS 10 Consolidated Financial Statements and IAS 28 in dealing with the loss of control of a subsidiary that is sold or contributed to an associate or joint venture. The amendments clarify that the gain or loss resulting from the sale or contribution of assets that constitute a business, as defined in IFRS 3, between an investor and its associate or joint venture, is recognized in full. Any gain or loss resulting from the sale or contribution of assets that do not constitute a business, however, is recognized only to the extent of unrelated investors’ interests in the associate or joint venture. These amendments must be applied prospectively and are effective for annual periods beginning on or after January 1, 2016, with early adoption permitted. These amendments will impact the Company to the extent that it undertakes future transactions of this nature, as this accounting approach differs to that which it would currently apply.

In November 2008, the Company funded the San Jose Reservoir Trust for US$13 million to ensure the continuity of the Company's operations in the San Jose Reservoir after 2018. Such trust is irrevocable and is a separate legal entity of the Company. The grantor is the Company, the trustee is the Banco de Credito del Peru and the beneficiary is the Company; therefore, the Company consolidates the trust. As of December 31, 2015, the trust total balance is US$15,803,000 and is presented as Available-for-sale financial assets (trust total balance of US$16,884,000 as of December 31, 2014).

During 2015, these investments, denominated in U.S. dollars, accrued losses net of taxes of US$757,000 (income of US$65,000 and loss of US$226,000 in 2014 and 2013, respectively) which are included in other comprehensive income.

Notes to the consolidated financial statements (continued)

| (b) | Impairment of long-lived assets -

I n accordance with its accounting policies and processes, each asset or Cash Generating Unit “CGU” is evaluated annually at year end, to determine whether there are any indications of impairment. If any such indications of impairment exist, a formal estimate of the recoverable amount is performed.

In assessing whether impairment is required, the carrying value of the asset or CGU is compared with its recoverable amount. The recoverable amount is the higher of the CGU’s fair value less costs of disposal (FVLCD) and value in use (VIU). Given the nature of the Company’s activities, information on the fair value of an asset is usually difficult to obtain unless negotiations with potential purchasers or similar transactions are taking place. Consequently, the recoverable amount for each CGU is estimated based on estimated discounted future estimated cash flows expected to be generated from the continued use of the CGUs using market based commodity price and exchange assumptions, estimated quantities of recoverable minerals, production levels, operating costs and capital requirements, and its eventual disposal, based on the latest life of mine (LOM) plans. These cash flows are discounted using a real pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the CGU.

Estimates include quantities of recoverable minerals, production levels, operating costs and capital requirements and sourced from out planning process, including the LOM plans, one-year budgets and CGU-specific studies.

As a result of the recoverable amount analysis performed during the year, the Company did not recognize an impairment loss related to mine properties in 2015. In 2014, the Company recorded an impairment loss amounting to US$541 million related to Conga, and no loss was recorded for Yanacocha (US$1,038 million for the year ended December 31, 2013: US$453 million related to Yanacocha and US$585 million related to Conga).

Key assumptions used for the impairment testing as of December 31, 2015:

The determination of value in use is most sensitive to the following key assumptions:

| - | Production volumes

| - | Commodity prices

| - | Discount rate

Production volumes: Estimated production volumes are based on detailed life-of-mine plans and take into account development plans for the mines agreed by management as part of planning process. Production volumes are dependent on a number of variables, such as: the recoverable quantities; the production profile; the cost of the development of the infrastructure necessary to extract the reserves; the production costs; the contractual duration of mining rights; and the selling price of the commodities extracted.

| F-133 |

Notes to the consolidated financial statements (continued)

As each producing mining unit has specific reserve characteristics and economic circumstances, the cash flows of the mines are computed using appropriate individual economic models and key assumptions established by management. The production profiles used were consistent with the reserves and resource volumes approved as part of the Company’s process for the estimation of proved and probable reserves and resource estimates.

Commodity prices: Forecasted commodity prices are based on management’s estimates and are derived from forward price curves and long-term views of global supply and demand, building on past experience of the industry and consistent with external sources. These prices were adjusted to arrive at appropriate consistent price assumptions for the different qualities and type of commodities, or, where appropriate, contracted prices were applied. These prices are reviewed at least annually.

Estimated prices for the current and long-term periods that have been used to estimate future revenues are as follows:

|  | Current |  |  | Long-term |
|  | US$ |  |  | US$ |
Gold (per ounce) |  |  | 1,106 |  |  |  | 1,300 |
Copper (per pound) |  |  | 2.50 |  |  |  | 3.00 |

Discount rate: In calculating the value in use, a pre-tax discount rate of 8.4% was applied to the pre-tax cash flows. This discount rate is derived from the Company’s post-tax weighted average cost of capital (WACC), with appropriate adjustments made to reflect the risks specific to the CGU.

| (b) | Provision for closure of mining units and explorations projects.

The Company's mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. The Company conducts its operations so as to protect the public health and environment and believes its operations are in compliance with all applicable laws and regulations in all material respects. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the amount of such future expenditures. Estimated future reclamation costs are based principally on legal and regulatory requirements.

The liability for reclamation or the Asset retirement obligation (“ARO”) comprises activities carried out by the Company in the restoration of mines and adjacent areas in the completion stage of the gold extraction process. Such activities include the restoration of mining locations, water treatment plant operations, as well as reforestation and land treatments.

|  |  | 578,959 |  |  |  | 557,457 |  |  |  | 460,127 |

The increase in the asset retirement obligation in 2015 relates to additional reclamation requirements caused by the impact of mining activities during 2015, additional costs for waste rock reclamation and new Peruvian regulatory requirements that extended the water treatment and monitoring requirements more than 20 years.

| (c) | Workers' profit sharing -

In accordance with Peruvian legislation, the Company maintains an employee profit sharing plan equal to 8% of annual taxable income. Distributions to employees under the plan are based 50% on the number of days that each employee worked during the preceding year and 50% on proportionate annual salary levels.

| 13. | Partners’ equity, net

| (a) | Partners’ contributions -

Partners’ contributions comprise 1,278,451,304 common partnership interests at par value of one Peruvian Sol each, fully subscribed and paid-in. Such partnership interest includes 720,407,310 shares that are owned by foreign investors.

Under current Peruvian regulations, there is no restriction on the remittance of dividends or repatriation of foreign investment, except as discussed in sections below.

The legal structure of the Company is that of a Peruvian limited liability partnership. Major features of such legal structure are: (i) the number of Partners cannot exceed 20, (ii) capital comprises the partnership interests, and (iii) there is no obligation to create a legal reserve.

| (b) | Retained earnings -

Distribution of earnings to Partners other than legal entities domiciled in Peru is subject to a withholding income tax charged to the partners.

| F-136 |

Notes to the consolidated financial statements (continued)

For individuals and non-resident legal entities, the applicable tax rate is 6.8% for dividend distributions in cash or non-monetary assets for fiscal years 2015 and 2016; whereas during fiscal years 2017 and 2018 the applicable tax rate will be 8.8%; and 9.3% from 2019, onward.

| 14. | Tax Situation

| (a) | Tax stabilization agreements

The Company has entered into the following tax stability agreements, each with a term of 15 years:

Mine | Effective | Date of the Tax Agreement | Tax Regimes in Force
Cerro Yanacocha | January 1, 2000 | September 16, 1998 | May 22, 1997
La Quinua | January 1, 2004 | August 25, 2003 | August 25,2003

The Cerro Yanacocha tax stabilization agreement expired on January 1, 2015 and is no longer in effect.

The agreement for La Quinua guarantees the Company's use of the tax regime shown in the table above and permits maintenance of its accounting records in U.S. dollars for tax purposes.

The Company determines taxable income based on its understanding and that of its legal advisors, of applicable tax legislation. Taxable income differs from pre-tax income disclosed within these financial statements by those items that the applicable tax legislation deems to be non-taxable or non-deductible.

For the year 2015, the income tax rate was 28%, except for the La Quinua mine, which was 29%.

On December 31, 2014, the Peruvian Government enacted modifications to Income Tax regulations, effective January 1, 2015. Among the modifications, a progressive income tax rate reduction was approved as follows: 28% for fiscal years 2015 and 2016; 27% for fiscal years 2017 and 2018; and 26% from 2019, onward.

| (b) | Other mining taxes -

| (i) | Law No.29788, Mining Royalties

On 28 September 2011, the Peruvian Government enacted new legislation to comprise a new mining tax payable to the Peruvian Government for extracting metallic and non-metallic mineral resources from its mining concessions.

Pursuant to this legislation, the mining royalty is payable quarterly based on sales and operating profit determined in accordance with IFRS. The royalty amount due is 1% of revenue. An additional mining tax due is calculated based on the level of operating profit up to a maximum applicable rate of 12%. This component of the new mining tax only applies to those projects that are not covered by a tax stabilization agreement. During 2015, 2014 and 2013, the amounts included in cost of production were US$2,456,000, US$8,291,000 and US$7,247,000, respectively and during 2014 and 2013 the amounts included in mining tax expense were US$ 1,714,000 and US$6,245,000, respectively.

The Special Mining Tax ("IEM") applies to mines not covered by a tax stabilization agreement. The IEM is payable on a quarterly basis with rates ranging from 2% to 8.4% of operating profit determined, in accordance with IFRS.

The rate varies depending on the level of operating profit. During 2015, 2014 and 2013 the amounts included in income and mining tax expense were US$1,838,000, US$5,479,000 and US$11,721,000, respectively.

| (iii) | Law No. 29790, Special Mining Burden

The Special Mining Burden ("GEM") applies to mines covered by a tax stabilization agreement. The GEM is payable on a quarterly basis with rates ranging from 4% to 13.12% of operating profit, determined in accordance with IFRS. The rate varies depending on the level of operating profit margin. The GEM applied to operations at Cerro Yanacocha and La Quinua in 2015, 2014 and 2013. This resulted in US$19,883,000, US$7,156,000 and US$22,707,000, respectively, of additional Income and mining tax expense.

| (iv) | Law No. 29471, Supplementary Fund

The Supplementary Fund for retirement of mining applies to metallurgical and steel workers, affiliated to the National Pension System (“SNP”) and the Private Pension System (“PPS”); and is applicable since May 11, 2012. This Fund is formed by employee and employer contributions which are distributed according to the following detail:

| - | Employers will contribute 0.5% of the annual income before taxes;

| - | Employees will contribute 0.5% of their monthly gross salary;

| - | The employer's contributions are paid before tax; therefore these amounts are deductible expenses for the year.

The new pension fund tax is calculated based on annual income determined in accordance with Peruvian generally accepted accounting principles and is payable quarterly. During 2015 and 2014, the amounts included in Income and mining tax expense amounted to US$459,000 and US$2,288,000, respectively.

Financial costs for the years ended December 31, 2015, 2014 and 2013 are mainly related to the unwinding of the discount of the reclamation and mine closure liability amounting to US$22,075,000, US$22,914,000 and US$18,113,000, respectively. See note 12(b).

| 20. | Commitments and contingencies

Unitization of properties -

In December 2000, as a result of the unitization plan carried out by the Partners, the Company signed several asset transfer and mining lease agreements with related entities. The main conditions are:

| - | The Company must pay to Chaupiloma, 3% of the quarterly net sales, according to the lease agreement. The mining rights subject to this 3% royalty are those identified in the lease agreement as part of the “Area of Influence of Chaupiloma”. Some of these mining rights are in exploitation and the rest of them in exploration.

| - | The Company must pay to S.M.R.L. Coshuro (“Coshuro”) and Buenaventura, 3% of the quarterly net sales, according to the transfer agreement. The mining rights subject to this 3% royalty are those identified in the transfer agreement, and are located out of the “Area of Influence of Chaupiloma” and within the “Area of Influence of the Joint Venture”. These mining rights are currently under exploration.

| - | The Company must pay to Los Tapados S.A., 3% of the quarterly net sales proceeds of mineral extracted from the transferred and leased concessions of Los Tapados S.A. The transferred and leased concessions of Los Tapados S.A. are also subject to a previously existing royalty on the minerals. These mining rights are currently under exploration.

Letters of Guarantee

The Company has signed Letters of Guarantee with various financial institutions in accordance with the Mine Closure Regulation approved by Supreme Decree No.033-2005 of the Ministry of Energy and Mines. The table below sets out the outstanding signed commitments at year ends by financial institution. In general, these letters of guarantee are renewed annually.

Legal proceedings -

Mercury spill in Choropampa

In June 2000, a carrier hired by Yanacocha spilled approximately 151 kilograms of mercury in the vicinity of the town of Choropampa, Peru, located 85 kilometers (53 miles) southeast of the mine. To date, Yanacocha has held court settlements with people affected by the incident. At December 31, 2015, there are 6 applicants with pending process. Yanacocha cannot reasonably predict the outcome of any of these claims; however, it is estimated that the maximum additional expense related to these demands will be US$1.5 million.

Action for Constitutional Relief against Conga Project Exploitation

On October 19, 2012, Marco Antonio Arana Zegarra ("Marco Arana") initiated an action for constitutional relief against the Mines and Energy Ministry and Yanacocha requesting that the Court orders to cease any threats of violation to life in an adequate and balanced environment; so that Court declared the suspension of the exploitation of the Conga Project and avoid Directorial Resolution No.351-2010-MEM/AM dated on October 27, 2010 that approved the Conga Environmental Impact Assessment.

By Court resolution No.1 dated October 23, 2012, the action was dismissed. On November 5, 2012, resolution No.1 was appealed by plaintiff and the hearing at Superior Court was held on March 4, 2013. The Cajamarca Superior Court confirmed the ruling of the judge that dismissed the claim.

On May 23, 2013, Marco Arana filed for a Constitutional remedy against the Cajamarca Superior Court decision and on June 3, 2013, the Cajamarca Superior Court accepted the Constitutional remedy filed by Marco Arana and the file has been sent to the Constitutional Court. On September 25, 2013, the Constitutional Court heard oral arguments from the parties and we are waiting their decision. To date the case maintains the same status.

Environmental

During 2015, the Company received administrative notifications from two national supervisory entities of mining investments (“OSINERGMIN”) and environmental impact (“OEFA”). The notifications are related to administrative infractions of security and environmental standards and others. According to Law N° 30230 approved on July 11th, 2014, OEFA will not impose administrative fines for a period of 3 years, unless 3 exceptions: (i) serious infraction; (ii) operate without a license or in forbidden place; and (iii) recidivism. The administrative fines amounted are between a range of 1 tax impositive unit (”UIT”) to 10,000 UIT (equivalent of US$1,000 and US$11,573,000). Management's and its legal counsel’s opinion, the Company should get a favorable outcome. Based on the accounting policy, Management has not recorded a provision for this contingency.

Open tax years -

The Tax Authority has the right to examine, and, if necessary, amend the Company’s income tax provision for the last four years. The Company’s income tax returns for the years 2011 through 2015 are open to examination by the tax authorities. For years 2002 through 2007, the Company is in the claim and appeal process. The tax administration is completing the audit of income tax of the year 2011.

| F-143 |

Notes to the consolidated financial statements (continued)

In Management’s and legal advisors’ opinion, there are sound legal grounds to sustain the Company’s tax positions; as a result, Management expects to obtain favorable results on these processes and any additional tax assessment would not be significant to the consolidated financial statements.

For the periods pending of examination, due to the many possible interpretations of current legislation, it is not possible to determine whether or not future reviews will result in tax liabilities for the Company. In the event that additional taxes are payable, including interest and surcharges, as a result of the Tax Authority reviews, they will be charged to expense in the period assessed. However, in Management’s and legal advisors’ opinion, any additional tax assessment would not be significant to the consolidated financial statements.

Tax contingencies -

Withholding income tax for fiscal years 2002 and 2003

The Tax Administration challenged the withholding tax rate applied on the technical assistance services provided by a non-resident supplier. The services were executed in Peru and also abroad; however, the Company was not able to prove that during the tax audit. Based on that, the Tax Administration considers that the services were wholly executed in Peru; therefore, the withholding tax rate should be 30% instead of 12%. The amount of the contingency involved is S/ 12.4 million (US$ 3.6 million). In Management's and its legal counsel’s opinion, that consideration has no support and the Company should obtain a favorable outcome in the appeal initiated against the tax authorities.

Health Contributions - ESSALUD

The Tax Administration considers that the bonus for closing the collective agreement and the collateral benefits granted to the unionized and non-unionized employees qualify as remunerative concepts; hence, taxed with the contribution to ESSALUD. The contingency amounts to S/ 6.5 million (US$ 2 million). In Management's and its legal counsel’s opinion, that interpretation has no support and the Company should obtain a favorable outcome in the appeal initiated against the tax authorities.

| 22. | Financial - risk management objectives and policies

The Company's operations are exposed to certain financial risks: some market risks (foreign exchange risk, interest rate risk and price risk), credit risk and liquidity risk. The Company's overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company's financial performance. The most important aspects in risk management are the following:

| (a) | Market risks -

| (i) | Foreign exchange risk -

Foreign exchange risk exposure arises from exchange rate fluctuations of balances denominated in different currencies than the U.S. dollar. Since transactions and balances denominated in foreign currency are not significant, the current exchange rate risk exposure is limited. Management has decided to assume the exchange risk exposure with the results of the Company's operations; therefore it has not engaged in hedging activities.

| (ii) | Interest rate risk -

The Company does not maintain significant interest-bearing assets or liabilities; therefore, operating income and cash flows of the Company are substantially independent from the changes in market interest rates. At December 31, 2015, the Company recognized interest income of approximately US$673,000 in connection with time deposits in financial institutions (US$499,000 in 2014 and US$489,000 in 2013).

| (iii) | Price risk -

The Company's financial instruments exposed to price risk are limited to its trade accounts receivable (exposed to gold price) and its available-for-sale financial assets, none of which show a material balance at the end of year, therefore no significant impact on the consolidated financial statements has arisen due to changes in their price that would need to be disclosed.

| (b) | Credit risk -

Credit risk is managed on a group basis by Newmont according to its policies. Financial instruments exposed to credit risk are cash and cash equivalents, investments in debt and equity instruments, trade accounts receivable and other accounts receivable. For banks and financial institutions, only independently rated parties with a minimum "A" rating are accepted. Regarding trade accounts receivable, according to the practice in the latest years, collections have generally been at full. A credit review of the portfolio is performed quarterly to determine any deterioration in credit quality. The Company does not foresee any significant losses that may arise from this risk.

| (c) | Liquidity risk -

Management administrates its exposure to liquidity risk through financing from internal operations, Company's partners and maintaining good relationships with local and foreign banks in order to maintain adequate levels of credit available. The Company currently has no existing bank lines of credit.

| F-146 |

Notes to the consolidated financial statements (continued)

The following table represents the analysis of the Company's financial liabilities, including estimated projected interests relating to financial obligations, considering the remaining period to reach such maturity as of the consolidated statement of financial position date:

|  | 2015 |  |  | 2014 |
|  | Less than 1 year |  |  | Less than 1 year |
|  | US$(000) |  |  | US$(000) |
Trade accounts payable |  |  | 56,447 |  |  |  | 69,788 |
Accounts payable to related parties |  |  | 10,792 |  |  |  | 51,071 |
Remuneration and similar benefits payable |  |  | 8,981 |  |  |  | 13,390 |
|  |  | 76,220 |  |  |  | 134,249 |

| (d) | Capital risk management -

The Company's objectives for managing capital are to safeguard the Company's ability to continue as a going concern in order to provide expected returns for partners and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

In order to maintain or adjust the capital structure, the Company may adjust the amount of dividends paid to its partners. No formal dividend policy exists.

| (e) | Fair value estimation -

Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

As required by accounting guidance, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assets that are measured at fair value on a recurring basis (at least annually) correspond to the San José Reservoir Trust assets.

The Company's San José Reservoir Trust assets are made up of marketable equity and debt securities that are valued using quoted market prices in active markets and as such are classified within Level 1 of the fair value hierarchy. The fair value of the marketable equity securities is calculated as the quoted market price of the marketable equity security multiplied by the quantity of shares held by the Company.

The Company's impairment loss is valued using valuation techniques to determine the WACC rate. These valuation techniques maximize the use of observable market data where it is available and rely as little as possible on entity specific estimates as such is classified within Level 2 of the fair value hierarchy.

On February 15, 2016, The Committee agreed unanimously on a distribution of a dividend to the partners in proportion to their social participation US$300,000,000 that corresponds to a part of unrestricted accumulated earnings as of December 31, 2014, which had been generated in the year 2011.

| 24. | Summary of significant differences between accounting principles followed by the Company and U.S. Generally Accepted Accounting Principles

The Company's financial statements have been prepared in accordance with International Financial Reporting Standards which differs in certain respects from U.S. GAAP. The effects of these differences are reflected in note 25 and are principally related to the items discussed in the following paragraphs:

| (a) | Impairment -

Under IFRS, the Company estimates the recoverable amount of an asset whenever there is an indication that the asset may be impaired. The recoverable amount is the higher of the fair value less costs of disposal and its value in use. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit.

In 2015, no impairment loss resulted for Yanacocha and Conga cash-generating units. In 2014, the Company recorded impairment losses amounting to US$541 million related to Conga, and no amount for Yanacocha (US$1,038 million for the year ended December 31, 2013: US$453 million related to Yanacocha and US$585 million related to Conga).

Under US GAAP, the Company used undiscounted cash flows to perform an impairment evaluation. No impairment losses resulted for Yanacocha and Conga cash-generating units in years 2013, 2014 and 2015.

For reconciling the net income/loss and net equity from IFRS to US GAAP, the Company eliminates the impairment loss and records the depreciation corresponding to the impaired assets under IFRS.

| (b) | Deferred workers’ profit participation

Under IFRS, the workers’ profit participation is calculated based on the Company’s taxable income and is recorded as an employee benefit (cost of production or administrative expense, depending on the function of the workers).

Under US GAAP, the workers’ profit sharing is treated in a similar way as income tax since both are calculated based on the Company’s taxable income. Therefore, the Company calculates a deferred workers’ profit participation resulting from the taxable and deductible temporary differences.

For reconciling the net income/loss and net equity from IFRS to US GAAP, the Company recognizes a deferred workers’ profit participation and the corresponding valuation allowance recorded in the year.

Notes to the consolidated financial statements (continued)

| (c) | Stripping activity asset -

Under IFRS, the stripping costs in the production phase of a surface mine are accounted for according to the accounting principle disclosed in note 2.

Under U.S. GAAP, the costs of clearing removal (stripping cost of production) incurred during the production stage are recorded as part of the production cost of inventories.

| (d) | Reclamation and mine closure –

Under IFRS, the liability was measured in accordance with IAS 37 and IFRIC 1. Upward and downward revisions in the amount of undiscounted estimated cash flows are discounted using the current market-based discount rate (this includes changes in the time value of money and the risks specific to the liability), see note 2.4 (j).

Under U.S. GAAP, upward revisions in the amount of undiscounted estimated cash flows are discounted using the current credit-adjusted risk-free rate. Downward revisions in the amount of undiscounted estimated cash flows are discounted using the credit-adjusted risk-free rate that existed when the original liability was recognized.

| (e) | Inventories -

Under IFRS, the cost of inventory mainly includes less depreciation as a result of the reduced base of property, plant and equipment due to the impairment recorded in prior years.

Under U.S. GAAP, the cost of inventory considers a higher depreciation since the items of property, plant and equipment have not been impaired.

| (f) | Deferred income tax –

The differences between U.S. GAAP and IFRS are re-measurements that lead to different temporary differences. According to the accounting policies in note 2.4 (l), the Company has to account for such differences.

During 2015, the Company recorded a valuation allowance of the deferred income tax asset recorded under IFRS which was higher by US$321,622,000 compared to the valuation allowance recorded under U.S. GAAP, mainly as a result of the impairment losses of prior years recorded under IFRS.

| 26. | New U.S. GAAP Accounting Pronouncements

Recently Issued Accounting Pronouncements -

Inventory -

In July 2015, ASU guidance was issued related to inventory simplifying the subsequent measurement of inventories by replacing the lower of cost or market test with a lower of cost and net realizable value test. The update is effective in fiscal years, including interim periods, beginning after December 15, 2016, and early adoption is permitted. The Company is currently evaluating this guidance and the impact it will have on net equity or net results.

Revenue recognition –

In May 2014, ASU guidance was issued related to revenue from contracts with customers. The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition. In August 2015, the effective date was deferred to reporting periods, including interim periods, beginning after December 15, 2017, and will be applied retrospectively. Early adoption is not permitted. The Company is currently evaluating this guidance and the impact it will have on net equity or net results.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Sociedad Minera Cerro Verde S.A.A.

We have audited the accompanying financial statements of Sociedad Minera Cerro Verde S.A.A. (a Peruvian company, subsidiary of Freeport-McMoRan Inc.), which comprise the statements of financial position as of December 31, 2015 and 2014, and the related statements of comprehensive income, statements of changes in equity and statements of cash flows for the years ended December 31, 2015, 2014 and 2013. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company´s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis of designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company´s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Sociedad Minera Cerro Verde S.A.A. as of December 31, 2015 and 2014, and the results of operations and its cash flows for each of the three years ended December 31, 2015, 2014 and 2013, in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (“IASB”) which differ in certain respects from the accounting principles generally accepted in the United States of America (see note 29 to the financial statements).

Sociedad Minera Cerro Verde S.A.A.

Notes to the financial statements

As of December 31, 2015, 2014 and 2013

| 1. | Identification and business activity of the Company

| (a) | Identification -

|  | Sociedad Minera Cerro Verde S.A.A. (here in after “the Company”) was incorporated in Peru on August 20, 1993, as a result of the privatization process of certain mining units carried out by the Peruvian State in that year. The Company has listed its shares on the Lima Stock Exchange since November 14, 2000.

Through its subsidiary Cyprus Climax Metals Company, Freeport-Minerals Corporation (“FMC”), a wholly owned subsidiary of Freeport-McMoRan Inc. (“Freeport”), owns 53.56% of the voting shares of the Company. SMM Cerro Verde Netherlands B.V. (a subsidiary of Sumitomo Metal Mining Company Ltd.) owns 21% of the voting share of the Company, Compañía de Minas Buenaventura S.A.A. owns 19.58%, and the minority stakeholders own the remaining 5.86%.

|  | The Company’s legal address is Jacinto Ibañez Street No. 315, Parque Industrial, Arequipa City and the ore deposits are located southwest of that city (Asiento Minero Cerro Verde S/N Uchumayo – Arequipa).

| (b) | Business activity -

The Company’s activities are regulated by the Peruvian General Mining Law and comprise the extraction, production and sale of copper cathodes and concentrates.

|  | Expansion of operations

In September 2015, the expansion project commenced operations and is expected to reach full rates in early 2016.

The project, with a cost of US$4.6 billion, expands processing capacity from 120,000 metric tons per day of ore to 360,000 metric tons per day, and targets incremental annual production of approximately 600 million pounds of copper and 15 million of molybdenum.

This expansion was financed with senior unsecured loans received by several banks lead by Citibank N.A. and with shareholders’ loans, currently subordinated to the senior unsecured loans before mentioned. See Note 12.

Notes to the financial statements (continued)

| (c) | Financial statements approval - The financial statements for the year ended December 31, 2015 were approved by Company´s Management on February 25, 2016 and, in Management’s opinion, they will be approved without changes by the Board of Directors and Shareholders’ Meetings to be held in the first quarter of 2016. The financial statements for the year ended December 31, 2014 were approved by the Board of Directors and Shareholders’ Meetings on March 27, 2015.

| 2. | Significant accounting principles and policies

| 2.1 | Basis of preparation -

The financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”), issued by the International Accounting Standards Board (“IASB”), and interpretations issued by the IFRS Interpretations Committee (“IFRIC”).

The financial statements have been prepared based on a historical cost basis, except for accounts receivable and/or payable related to embedded derivatives that have been measured at fair value. The financial statements are presented in United States dollars (US$) and include the years ended December 31, 2015, 2014 and 2013. Unless otherwise indicated, all values have been rounded to the nearest thousand.

| 2.2. | Summary of significant accounting policies and practices -

| (a) | Currency -

The financial statements are presented in US dollars, which is the Company’s functional currency.

Foreign currency transactions are those carried out in a currency other than the functional currency. Foreign currency transactions are initially recorded in the functional currency at the rate of exchange ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated to the spot rate of exchange ruling at the reporting date.

Gains and losses as a result of the difference in the exchange rate when monetary items are liquidated or when converting monetary items at exchange rates that are different from those used for their initial recognition are recognized in the statements of comprehensive income for the year.

The Company uses exchange rates published by the Superintendent of Banks, Insurance and Pension Fund Administrator. As of December 31, 2015, the published exchange rates were S/3.408 for US$1 for buying and S/3.413 for US$1 for selling (S/2.981 for US$1 for buying and S/2.989 for US$1 as of December 31, 2014).

| F-161 |

Notes to the financial statements (continued)

| (b) | Financial instruments: Initial recognition and subsequent measurement -

A financial instrument is any agreement which originates a financial asset of the entity and a financial liability or equity instruments of other entity.

| (i) | Financial assets -

The Company determines the classification of its financial assets at initial recognition in accordance with IAS 39, “Financial Instruments: Recognition and Measurement”.

All financial assets are recognized initially at fair value plus transaction costs that are attributable to the acquisition of the financial asset. The Company’s financial assets include accounts receivable and embedded derivatives.

Receivables -

The Company’s accounts receivables include trade accounts receivables to related parties and third parties and other accounts receivable.

Accounts receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. After initial measurement, the accounts receivables are subsequently carried at amortized cost using the effective interest method less any provision for impairment (i.e. allowance for doubtful accounts).

The Company assesses whether, as of the date of the financial statements, there is objective evidence of impairment in the value of the receivable. Any resulting impairment is measured as the difference between the book value of the receivable and the present value of the estimated future cash flows, discounted at an original effective interest rate or one applicable to a similar transaction. The carrying amount of the receivable is reduced by means of an allowance account and recognized in the statements of comprehensive income.

Embedded derivatives -

The Company’s copper sales are provisionally priced at the time of shipment. The provisional prices are finalized in a specified future month based on quoted London Metal Exchange (LME) monthly average prices. The Company receives market prices based on prices in the specified future month, which results in price fluctuations recorded through revenues until the date of settlement. The Company records revenues and commercial invoices at the time of shipment based on the current LME prices, which result in an embedded derivative that is required to be separated from the host contract.

The Company’s embedded derivatives from sales are measured at fair value (based on LME spot copper prices) with subsequent changes recognized in the statements of comprehensive income until the month of maturity.

| F-162 |

Notes to the financial statements (continued)

| (ii) | Financial liability -

All financial liabilities are recognized initially at fair value and, in the case of accounts payable and other financial liabilities, net of directly attributable transaction costs. The Company´s financial liabilities include trade and other payables, other financial liabilities and embedded derivatives.

Loans-

Loans are initially recognized at their fair value, net of directly attributable transaction costs. After initial recognition, loans are subsequently measured at amortized cost using the effective interest rate method. Gains and losses are recognized in the statement of comprehensive income when the liabilities are derecognized as well as through the amortization process.

Amortized cost is calculated taking into account any discount or premium on acquisition and fees or costs that are an integral part of the effective interest rate. Amortization under the effective interest rate method is included as financial costs in the statement of comprehensive income.

| (iii) | Offsetting of financial instruments –

Financial assets and financial liabilities are offset and the net amount is reported in the statements of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

| (c) | Inventories –

Inventories are stated at the lower of cost or the net realizable value. Inventory of materials and supplies, as well as in progress and finished products are determined using the weighted-average cost method. The cost of finished goods and in - process inventory (i.e., stockpiles) includes labor and benefits, supplies, energy and other costs related to mining and processing of minerals. Net realizable value is the estimated future sales price based on forward metal prices (at the year that are expected to be processed), less estimated costs to complete production and bring the inventory to sale.

The current portion of work in process is determined based on the expected amounts to be processed with the next twelve months. Inventories not expected to be processed within the next twelve months are classified as long-term.

No write-down of inventories was recorded as of December 31, 2015 and 2014.

Provision for obsolescence -

Obsolescence allowances are established based on an item-by-item analysis made by Management. Any amount of obsolescence is charged to the statements of comprehensive income in the year of occurrence.

| F-163 |

Notes to the financial statements (continued)

| (d) | Property, plant and equipment -

Property, plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. The initial cost of an asset comprises its purchase price or construction cost, including customs duties and non-reimbursable taxes, as well as any costs directly attributable to bringing the asset into operation, the initial estimate of the rehabilitation obligation and, in the case of qualifying assets, the cost of borrowing. The capitalized value of a finance lease is also included in this caption.

Major maintenance and repairs -

Expenditure on major maintenance refits or repairs comprises the cost of replacement assets or parts of assets and overhaul costs. Where an asset that was separately depreciated and is now written off is replaced, and it is probable that the future economic benefits associated with the item will flow to the Company through an extended life, the expenditure is capitalized. All other day-to-day maintenance and repairs costs are expensed as incurred.

Where part of the asset was not separately considered as a component and therefore not depreciated separately, the replacement value is used to estimate the carrying amount of the replaced assets which is immediately written off.

Depreciation –

Land is not depreciated. Depreciation of assets directly related to the useful life of the mine is calculated using the UOP method based on the mine’s proven and probable reserves. Other assets are depreciated using the straight-line method based on the following estimated useful lives:

|  | Years
Buildings and other constructions |  | Between 15 and 35
Machinery and equipment |  | Between 3 and 25
Transportation units |  | 7
Furniture and fixtures |  | 7
Other equipment |  | Between 3 and 25

The asset’s residual values, useful lives and methods of depreciation are reviewed, at each reporting period and adjusted prospectively, if appropriate.

Disposals –

An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of tproperty, plant and equipment (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statements of comprehensive income when the asset is derecognized.

| F-164 |

Notes to the financial statements (continued)

| (e) | Exploration and development costs –

Exploration costs -

Mineral exploration costs, as well as drilling and other costs incurred for the purpose of obtaining proven and probable reserves, or identifying new mineral resources at development or production stage properties, are charged to the statements of comprehensive income as incurred.

Development costs -

Development costs are capitalized based on the Management´s judgment, when the economic and technological feasibility of the project is confirmed, which is generally when the development or expansion project has reached a milestone in accordance with a model established by the Company. These costs are amortized when production beings, on the units-of-production basis over the proven and probable reserves. Development costs necessary to maintain production are expensed as incurred.

| (f) | Stripping costs -

In accordance with IFRIC 20, “Stripping Cost in the Production Phase of a Surface Mine,” stripping costs incurred in the production phase are capitalized as a component of property, plant and equipment (see Note 9) if the stripping activity improves access to the ore body or enhances an existing asset. The stripping activity asset is subsequently amortized using the UOP method.

| (g) | Impairment of non-financial assets -

At each reporting date, the Company evaluates if there is any indication that an asset may be impaired. If any indication exists, the Company estimates the recoverable amount of the asset. The recoverable amount of an asset is the higher of its fair value less costs of disposal and its value in use and is determined for the assets of the mine as a whole, since there are no assets that generate cash revenues independently.

When the carrying amount of an asset exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset.

Impairment losses are recognized in the statements of comprehensive income under the categories of expenses consistent with the function of the impaired asset. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset’s recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of the asset does not exceed if recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the statements of comprehensive income.

| F-165 |

Notes to the financial statements (continued)

| (h) | Intangible assets -

|  | Intangible assets are recognized initially at cost. After the initial recognition, the intangible assets are recorded at its cost less accumulated amortization and any accumulated loss for impairment of use, if applicable.

| (i) | Provisions -

General -

Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefit will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. The expense relating to a provision is presented in the statements of comprehensive income, net of any reimbursement.

If the effect of the time value of money is material, provisions are discounted using a rate that reflects, when applicable, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognized as finance costs in the statements of comprehensive income.

Provision for remediation and mine closure -

The Company records a provision for remediation and mine closure when a contractually or legally enforceable obligation arises. The Company estimates the present value of its future obligation for mine closure and increases the carrying amount of the related “Asset Retirement Cost” - ARC, which is included in property, plant and equipment. Subsequently, the mine closure provision is accreted to full value over time and recognized as an interest cost considered in the initial fair value estimate. The related ARC is depreciated using the units-of-production method during the economic life of the mine.

The Company evaluates its provision for remediation and mine closure quarterly and makes adjustments to estimates and assumptions, including future costs and discount rates, as applicable. Changes in the fair value of provision for remediation and mine closure or the useful life of the related asset are recognized as an increase or decrease in the book value of the provision and the related ARC in accordance with IAS 16. Any decrease in the mine closure provision and related ARC may not exceed the carrying amount of the asset. If it does, any excess over the carrying value is taken immediately to the statements of comprehensive income.

| (j) | Revenue recognition -

The Company primarily sells copper cathodes and concentrates in accordance with sales contracts entered into with its customers. Revenues comprise the fair value of the sale of goods, net of related sales taxes. The Company recognizes revenue when the amount can be reliably measured, it is probable that economic benefits will flow to the Company and all significant risks (including title and insurance risk) and rewards of ownership have transferred to the customer. Revenue is not considered reliably measured until all contingencies relating to the sale have been resolved.

| F-166 |

Notes to the financial statements (continued)

Sales of copper cathodes and concentrates –

Domestic sales of copper cathodes and concentrates are recognized when the Company has delivered the goods to the shipping company designated by the customer. Revenue associated with foreign sales of copper cathodes and copper concentrates is recognized when all significant risks and rewards of ownership have transferred to the customer, which is typically when the inventory has passed over the vessel’s rail at the port of loading.

As described in note 2.2(b), the Company’s copper sales are provisionally priced at the time of shipment. The provisional prices are finalized in a specified future month in accordance with the terms specified in the related sales contract and based on quoted LME monthly average prices. The Company receives market prices in the specified future month, and the effect of the changes in such market prices are recorded as revenues until the specified future month. The Company records revenues and commercial invoices at the time of shipment based on the current LME prices, which result in an embedded derivative that is bifurcated from the host contract.

Since year 2014, the Company’s revenues are subject to royalties for two governmental entities. These funds will be used for these entities as part of their operational budgets for the supervision of energy and mining investment and the environment. The calculation for the OSINERGMIN contribution is 0.21% of invoiced sales for 2014, 0.19% for 2015, and 0.16% for 2016, and the calculation for the OEFA contribution is 0.15% of invoiced sales for 2014 and 2015, and 0.13% for 2016. These royalties are presented as reduction of revenues (see note 17).

| (k) | Borrowing cost -

Costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as finance part of the cost of an asset. A qualifying asset is one whose value is greater than US$1 million and requires a longer period to 12 months to get ready for its intended use. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consist of interest and other costs that the Company incurs in connection with the borrowing of funds.

| (l) | Income taxes, deferred taxes and other taxes -

Current income tax -

Current income tax assets and liabilities are measured at the amounts expected to be recovered from or paid or the tax authority. The tax rates and tax laws used to compute the amount are those that are enacted or substantially enacted, at the reporting period. The Company calculates the provision for current income tax based on the tax stability agreement described in Note 16(a).

| F-167 |

Notes to the financial statements (continued)

Deferred income tax -

Deferred income tax is provided using the liability method on temporary differences between the tax basis of assets and liabilities and their carrying amounts for financial reporting purposes at their reporting date. Deferred tax liabilities are recognized for all taxable temporary differences. Deferred income tax assets are recognized for all deductible temporary differences, to the extent that is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted at the reporting date.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right to set off current tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Peruvian mining royalties and special mining tax -

On September 29, 2011, Law No. 29788 (which amended Law No. 28528) was enacted creating a new mining tax and royalty regime in Peru.

| - | Stability agreement effective until December 31, 2013

Under the new regime, companies that do not have stability agreements were subject to a revised royalty and a special mining tax. The Company operated under a stability agreement and therefore was not subject to the revised royalty and special mining tax until its stability agreement expired on December 31, 2013. The Peruvian government also created a special mining burden that companies with tax stability agreements could elect to pay. The Company elected to pay this special mining burden during the remaining term of its stability agreement. See Note 16 (c).

| - | Stability agreement effective since January 1, 2014

Beginning January 1, 2014, under the terms of the new stability agreement, the Company will pay mining royalties and special mining tax for all its production based on Law No. 29788.

| F-168 |

Notes to the financial statements (continued)

| - | Mining Royalties and Special Mining Tax are in the scope of IAS 12 “Income Tax” and are considered income tax.

Supplementary Retirement Fund –

Law No. 29741, enacted on July 9, 2011, created a Mining and Metallurgical Retirement Fund, which is applicable to the Company starting 2014. Under the terms of its new 15-year stability agreement, the base of calculation of this contribution is 0.5% of pre-tax income. These funds will be used for the jubilee of the mining and metallurgical workers. The contribution is presented as income tax due to the same basis of calculation.

| (m) | Benefits to employees -

Salaries and wages, bonuses, post-employment benefits and vacations are calculated in accordance with IAS 19, "Employee Benefits" and are calculated in accordance with current Peruvian legislation based on the accrual basis.

Workers’ profit sharing

The Company recognizes workers’ profit sharing in accordance with IAS 19, “Employees Benefits". Workers' profit sharing is calculated in accordance with the Peruvian law (Legislative Decree No. 892), and the applicable rate is 8% over the taxable net base of current year. According to Peruvian law, the limit in the workers' profit sharing that an employee can receive is equivalent to 18 months of wages, and any excess above such limit has be transferred to the Regional Government and “National Fund for Employment’s Promotion and Training” (“FONDOEMPLEO”). The Company’s workers’ profit sharing is recognized as a liability in the statement of financial position and as an operating expense in the statements of comprehensive income (See note 18).

| (n) | Basic and diluted earnings per share -

Basic and diluted earnings per share have been calculated based on the weighted average number of common shares held during the period. When the number of shares is modified as a result of capitalization of retained earnings, the net income per basic and diluted share is adjusted retroactively for all of the periods reported. For the years ended as of December 31, 2015, 2014 and 2013, the Company did not have any financial instrument with dilutive effects; as a result, the basic and diluted shares are the same in all years presented.

| (o) | Fair value measurement -

The Company measures its embedded derivatives, at fair value at each statement of financial position.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

| F-169 |

Notes to the financial statements (continued)

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described, as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

| - | Level 1 — Quoted (unadjusted) market prices in active markets for identical assets or liabilities

| - | Level 2 — Valuation techniques for which the lowest-level input that is significant to the fair value measurement is directly or indirectly observable

| - | Level 3 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above

| 3. | Accounting estimates, judgments and assumptions –

The preparation of the Company’s financial statements according to IFRS requires Management to make judgments, estimates and assumptions to determine the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities to the date of financial statements, and for the reported amounts of revenues and expenses for the years finished as of December 31, 2015, 2014 and 2013.

Estimates and assumptions are continuously evaluated and are based on the experience of Management and other factors, including expectations of future events that are reasonable under current circumstances; however, actual results could differ from these estimates.

Information about estimations and judgments taken into account by Management in the preparation of the financial statements follows:

| 3.1 | Judgments -

| (a) | Contingencies -

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential quantum of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

| (b) | Stripping cost -

The Company incurs waste removal costs (stripping costs) during the development and production phases of its surface mining operations. During the production phase, stripping costs (production stripping costs) can be incurred both in relation to the production of inventory in that period and the creation of improved access and mining flexibility in relation to ore to be mined in the future. The former are included as part of the costs of inventory, while the latter are capitalized as a stripping activity asset, where certain criteria are met.

| F-170 |

Notes to the financial statements (continued)

Once the Company has identified its production stripping for each surface mining operation, it identifies the separate components of the ore bodies for each of its mining operations. An identifiable component is a specific volume of the ore body that is made more accessible by the stripping activity. Significant judgment is required to identify and define these components, and also to determine the expected volumes (e.g., in tons) of waste to be stripped and ore to be mined in each of these components.

| 3.2 | Estimates and assumptions -

| (a) | Determination of mineral reserves and resources -

Ore reserves are estimates of the ore quantity that can be economically and legally extracted from the mine concessions. The Company estimates its ore reserves based on information compiled by individuals qualified in reference to geological data about the size, depth and form of the ore body, and requires of geological judgments in order to interpret the data.

The estimation of recoverable reserves is based on factors such as estimated exchange rates, commodity prices, future requirements of capital and production costs, together with geological hypothesis and judgments made when estimating the size and quality of ore. Revisions in reserve or resource estimates have an impact on the value of mining properties, property, plant and equipment, provisions for cost of mine closure, recognition of assets for deferred taxes and depreciation and amortization of assets.

| (b) | Units of production depreciation -

Estimated economically recoverable reserves are used in determining the depreciation and/or amortization of mine-specific assets. This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life-of-mine production. The life of each item, which is assessed at least annually, has regard to both its physical life limitations and present assessments of economically recoverable reserves of the mine property at which the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves.

| (c) | Provision for remediation and mine closure -

The Company assesses its provision for remediation and mine closure quarterly. It is necessary to make estimates and assumptions in determining this provision, including cost estimates of activities that are necessary for the rehabilitation of the site, technological and regulatory changes, interest rates and inflation rates. As discussed in Note 2.2(i), estimated changes in the fair value of the provision for remediation and mine closure or the useful life of the related assets are recognized as an increase or decrease in the book value of the provision and related asset retirement cost (ARC) in accordance with IAS 16, “Property, Plant and Equipment”.

| F-171 |

Notes to the financial statements (continued)

If any change in the estimate results in an increase to the provision for remediation and mine closure and related ARC, the Company shall consider whether or not this is an indicator of impairment of the assets and will apply impairment tests in accordance with IAS 36, “Impairments of Assets”.

| (d) | Inventories -

Net realizable value tests are performed at least annually and represent the estimated future sales price of the product based on prevailing spot metals prices, less estimated costs to complete production and bring the inventory to sale. Additionally, in calculating the net realizable value of the Company’s long-term stockpiles, Management also considers the time value of money.

Mill and leach stockpiles generally contain lower grade ores that have been extracted from the ore body and are available for copper recovery. For mill stockpiles, recovery is through milling and concentrating. For leach stockpiles, recovery is through exposure to acidic solutions that dissolve copper and delivery it in solution to extraction processing facilities.

Because it is generally impracticable to determine copper contained in mill and leach stockpiles by physical count, a reasonable estimation method is employed. The quantity of material delivered to mill and leach stockpiles is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated copper grades of material delivered to mill and leach stockpiles.

Expected copper recovery rates for mill stockpiles are determined by metallurgical sampling. The recoverability of copper in mill stockpiles, once entered into the production process, can be produced into copper concentrate rapidly.

Estimated copper recovery rates are determined using laboratory tests, historical trends and other factors. Ultimate recovery of copper contained in leach stockpiles can vary significantly depending on several variables, including type of copper recovery, mineralogy and the size of the rocks. Processes and recovery rates are monitored continuously, and recovery rates are adjusted periodically as additional information becomes available and as related technology changes.

| (e) | Asset impairment -

Management has determined that the Company’s operations consist of one cash generating unit. Therefore, the Company’s operations are evaluated annually in order to determine if there are impairment indicators. If any such indication exists, the Company makes an estimate of the recoverable amount, which is the greater of the fair value less costs to sell and the value in use. These assessments require the use of estimates and assumptions, such as long-term commodity prices, discount rates, operating costs, and others.

| F-172 |

Notes to the financial statements (continued)

Fair value is defined as the amount that would be obtained from the sale of the asset in an arm’s length transaction between willing and knowledgeable parties. The fair value of assets is generally determined as the current value of future cash flows derived from the continuous use of the asset, which includes estimates, such as the cost of future expansion plans and eventual disposal, while applying assumptions that an independent market participant may take into account. The cash flows are discounted by applying a discount rate that reflects current market, the time value of money and the risks specific to the asset.

As a result of the decline in copper prices, the Company evaluated its long-lived assets for impairment as of December 31, 2015, which did not result in any impairment charges. The determination of value in use is considered to be a Level 3 fair value measurement, as it is derived from valuation techniques that include inputs that are not based on observable market data. The Company considers the inputs and the valuation approach to be consistent with the approach taken by market participants.

The key assumptions/inputs used in the determination of the Company’s fair value included production volumes, copper prices and discount rates. Estimated production volumes are based on detailed life-of-mine plans and are dependent on a number of variables, including recoverable quantities, the production profile, production costs, and the selling price of the commodities extracted. Short-term copper prices used in determining value in use ranged from US$2.13 to US$2.16 per pound, which were based on quoted forward market prices as of December 31, 2015, and the long-term copper price assumption was US$3.00 per pound, which reflects management’s long-term view of global supply and demand. In addition to estimates of production volumes and copper price assumptions, the determination of value in use was based on an post-tax discount rate of 8.5% applied to the future estimated cash flows; which was derived from the weighted average cost of capital, with appropriate adjustments made to reflect the risks specific to the Company.

There was no asset impairment loss for the Company as of December 31, 2015 and 2014.

| 4. | Standard issued but not effective

Following is a summary of improvements and amendments to IFRS that are not yet effective but will be applicable to the Company.

IFRS 9 Financial Instruments

In July 2014, the IASB issued the final version of IFRS 9 Financial Instruments that replaces IAS 39 and all previous versions of IFRS 9. IFRS 9 brings together all three aspects of the accounting for financial instruments project: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for annual periods beginning on or after January 1, 2018, with early application permitted. The adoption of IFRS 9 is not expected to have a significant effect on the classification and measurement of the Company’s financial assets and liabilities.

| F-173 |

Notes to the financial statements (continued)

IFRS 15 Revenue from Contracts with Customers

IFRS 15 was issued in May 2014 and establishes a five-step model to account for revenue arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. The new revenue standard will supersede all current revenue recognition requirements under IFRS. Either a full retrospective application or a modified retrospective application is required for annual periods beginning on or after January 1, 2018. Early adoption is permitted. The Company is currently assessing the impact of this guidance on its financial reporting and disclosures, but at this time does not expect the adoption of IFRS 15 to have a material impact on its financial statements.

| 5. | Cash and cash equivalents

| (a) | This item is made up as follows:

|  | 2015 |  |  | 2014 |
|  | US$(000) |  |  | US$(000) |
Cash in banks |  |  | 5,604 |  |  |  | 7,698 |
Cash equivalents (b) |  |  | 348 |  |  |  | 11,876 |
|  |  | 5,952 |  |  |  | 19,574 |

| (b) | Cash equivalents comprises a portfolio of investments in highly marketable liquid investments (investments classified as “AAA” by Standard & Poor’s and Moody’s), which yield variable returns, and are classified as cash equivalents because they are readily convertible to known amounts of cash. During the year 2015, Management used the majority of its investments for its short-term cash needs. Because of the short maturity of these investments, less than 90 days, the carrying amount of these investments corresponds to their fair value at the date of the financial statements. Changes in the fair value of these investments are insignificant.

| 6. | Trade accounts receivable

Trade accounts receivable are generated primarily from the Company’s cathode and copper concentrate sales, are denominated in US dollars, have current maturities, do not bear interest and have no specific guarantees.

| (b) | Mainly attributable to purchases related to the expansion of the Company´s production unit (See Note 1(b)). The Company expects to recover the VAT credits in short and long-term.

| (c) | Corresponds to disbursements made by the Company related to prepayment of income tax, which the Company expects to use to offset with future tax obligations or will be refunded to the Company by the Tax Authority.

| (d) | Corresponds to disbursements made by the Company under protest in connection with disputed tax assessments from years 2004 to 2010. The most significant issues observed are:

| - | Deductibility of certain management fees rendered by a related entity;

| - | Application of accelerated depreciation deduction related to the first concentrator plant as it claims the Company is not entitled to this benefit under its 1998 stability agreement; and

| - | Certain disbursements would qualify as fixed assets.

These claims are currently under review in the Tax Court. According to current tax procedures and time frame for resolving these types of claims, the Company and its legal advisors expect favorable resolution in all cases due to the strength of their arguments.

| (e) | Corresponds to payments made under protest by the Company in connection to installment program approved by the tax authority associated with mining royalties for the period December 2006 to December 2008, which is described in Note 16(e). Management expects that the resolution of this matter will be favorable to the Company.

| (b) | Work-in-process inventories represent mill and leach stockpiles which contain higher grade ores and medium and lower grade ores that have been extracted from the open pit and are available for copper recovery. Based on the mine future plan production, the Company identifies the portion of inventory that is going to be classified as short or long term. For mill stockpiles, recovery is through milling and concentrating. For leach stockpiles, recovery is through exposure to acidic solutions that dissolve copper and delivery it in solution to extraction processing facilities (see note 3.2(d)).

Trade accounts payable are mainly originated by the acquisition of materials, supplies and spare parts for the Company’s mining activities. These obligations are mainly in US dollars, have current maturities and do not accrue interest. No guarantees have been granted. As of December 31, 2015, trade accounts payable includes US$279,378,000 related to capital projects mainly associated with Cerro Verde’s production unit expansion (US$318,957,000 as of December 31, 2014).

The Legislative Decree No. 892 (L.D. 892), issued in 1996, regulates the right of workers to participate in a company’s profits that performs activities generating third categories income and requires companies domiciled in Peru to compute and pay to employees a share of the profits generated by the companies for which they work. The Company’s liability for workers’ profit sharing is recognized according to the policy described in note 2.2(m).

The workers’ profit sharing is recognized as an operating expense in the statements of comprehensive income. The amount of workers’ profit sharing paid to employees for the years 2015, 2014 and 2013 are recognized as a cost of sales of goods (see note 18). Additionally, during 2015, 2014 and 2013 no excess of workers´ profit sharing was calculated between the total workers’ profit sharing liability and the amount paid or due to employees.

| (b) | In March 2014, the Company entered into a five-year US$1.8 billion senior unsecured credit facility with several banks, led by Citibank N.A., as administrative agent.

| F-178 |

Notes to the financial statements (continued)

The credit facility allows for term loan borrowings up to the full amount of the facility, less any amounts issued and outstanding under a $500 million sublimit. Interest on amounts drawn under the term loan is based on London Interbank Offered Rate (LIBOR) plus a spread (currently 2.4 %) based on the Company´s total net debt to earnings before interest, taxes, depreciation and amortization (EBITDA) ratio as defined in the agreement. The disbursements were mainly used to finance a portion of the Company´s expansion project.

The credit facility amortizes in three installments in amounts necessary to comply the commitment of the requested amounts under the loan. The first installment should paid at least 15% (85% of the outstanding balance) as of September 30, 2017, the second installment at least 30% (70% of the outstanding balance) as of March 31, 2018, and the third installment not less than 65% (35% of the outstanding balance) as of September 30, 2018, with the remaining balance due on the maturity date of March 10, 2019.

As of December 31, 2015, the Company has used the total credit line (US$1.8 billion). No letters of credit were issued.

There are no guarantees provided for the credit facility.

|  | Covenants -

|  | As part of the commitments made in relation to the above debt, the Company must comply with the following financial ratios listed below:

| i. | Total Net Debt to EBITDA Ratio: The Company shall not permit the Total Net Debt to EBITDA Ratio on the last day of any fiscal quarter to exceed 4.75 to 1 (3.5 to 1 in 2014).

| ii. | Interest Coverage Ratio: The Company shall not permit the Interest Coverage Ratio on the last day of any fiscal quarter to be less than 3.0 to 1.

The financial ratios mentioned above apply to financial statements of the Company, which should be calculated as of each quarter ending in March, June, September and December of each year since 2014.

As of December 31, 2015, the Company was in compliance with all of its covenants, which are monitored by Management each quarter.

| (c) | As of December 31, 2015 corresponds to bank promissory notes with Banco Interbank to finance its working capital needs, with an interest rate of 1.29%. The maturity date of these notes has been renewed through February 2016.

| F-179 |

Notes to the financial statements (continued)

| (d) | In December 2014, the Company entered into shareholder loan agreements with, or affiliates of, Freeport Minerals Corporation, Compañía de Minas Buenaventura S.A.A. and SMM Cerro Verde Netherlands B.V., that are currently subordinated to the senior unsecured credit facility (described in note 12(b)). These agreements allow for borrowings up to an amount of US$800 million in aggregate. As of December 31, 2015, the Company had borrowed US$600.9 million under these loan agreements, including US$0.9 million of interest. The interest rate is currently calculated based on the LIBOR rate plus the average rate of the senior unsecured credit facility, plus 0.5% (currently 3.13%). In the event these loans are no longer subordinated to the senior unsecured credit facility, the rate would be LIBOR plus the current spread on the credit facility. The loans mature on December 22, 2019, unless at that time there is senior financing associated with the expansion project that is senior to the loans, in which case the loans mature two years following the maturity of the senior financing.

There are no guarantees provided for these loans.

Notes to the financial statements (continued)

According to the Company’s accounting policies, the provision for remediation and mine closure represents the present value of the costs that are expected to be incurred in the closure period of the operating activities of the Company. Closure budgets are reviewed regularly to take into account any significant change in the studies conducted. Nevertheless, the closure costs of mining units will depend on the market prices for the closure works required, which would reflect future economic conditions. Also, the time when the disbursements will be made depends on the useful life of the mine, which will be based on future metals prices.

As of December 31, 2015, the future value of the provision for remediation and mine closure and environmental liabilities was US$368,753,000, which was discounted using the annual risk-free rate of 2.81%, resulting in an updated liability of US$161,270,000 (as of December 31, 2014, the future value of the provision for remediation and mine closure and environmental liabilities was US$257,451,000, which was discounted using the annual risk-free rate of 2.59%, resulting in an updated liability of US$119,948,000). The Company considers that this liability is sufficient to meet the current environmental protection laws approved by the MEM.

As of December 31, 2015 and 2014, the Company has issued letters of credit to Ministry of Energy and Mines amounting to US$21,539,000 and US$14,851,000, respectively, to secure mine closure plans for its mining unit.

| 16. | Tax situation

| (a) | Current tax regime -

On February 13, 1998, the Company signed an Agreement of Guarantees and Measures to Promote Investments with the Government of Peru, under the Peruvian General Mining Law. Upon approval of the agreement, the Company had tax stability for a period of 15 years from January 1, 1999 to December 31, 2013 and was subject to the tax regulations in force at May 6, 1996.

|  | On July 17, 2012, the Company entered into a new Agreement of Guarantees and Measures to Promote Investments with the Government of Peru, under the General Mining Law and in connection with the Expansion of Cerro Verde´s production mining unit Project. By means of this agreement, the Company is subject to the tax regulations in force at July 17, 2012. The term of this agreement is 15 years from January 1, 2014 to December 31, 2028.

By means of Law No. 30296 enacted on December 31, 2014, the Peruvian government introduced certain amendments to the Income Tax Law, effective January 1, 2015, which will be applied to the Company since the maturity of the stability agreement (January 1, 2029). The most relevant are listed below:

| - | There will be a gradual reduction of the corporate income tax from 30% to 28% in 2015 and 2016; to 27% in 2017 and 2018; and to 26% in 2019 and thereafter;

| - | There will be a gradual increase of the withholding income tax to dividends from 4.1% to 6.8% in 2015 and 2016; to 8.0% in 2017 and 2018; and to 9.3% in 2019 and thereafter. These rates will be applicable to the distributed or approved dividends, whichever first occurs, effective January 1, 2015;

| - | The retained earnings or other items subject to generate taxable dividends, obtained until December 31, 2014 will be subject to a rate of 4.1%.

| F-185 |

Notes to the financial statements (continued)

| (b) | The income tax rate applicable to the Company is 32% beginning 2014 according to the new agreement mentioned above. For the years ended December 31, 2015, 2014 and 2013, the taxable income according to the tax law is calculated from the profit before income tax and profit sharing for these years, and is as follows:

| F-186 |

Notes to the financial statements (continued)

| (c) | As described in Note 2.2(l), Law No. 29788 was enacted creating a new mining tax and royalty regime in Peru. Because the Company stabilized the tax regime in force at May 6, 1996, it was not subject to the revised royalty and special mining tax until December 31, 2013, date on which the related tax stability expired. However, the Company elected to pay a special mining burden during the remaining term of its tax stability agreement. For the years ended December 31, 2015, 2014 and 2013, the Company recorded a tax provision of US$14,599,000, US$52,116,000 and US$63,178,000 respectively, related to mining taxes.

| (d) | The Tax Authority has the right to examine, and, if necessary, amend the Company’s income tax provision for the last four years. The Company’s income tax and VAT for the years 2011 through 2015 are open to examination by the tax authorities. To date, SUNAT has concluded its review of the Company’s income tax and VAT exams through the year 2010, and the Company is in the claim and appeal process for the years 2002 through 2010.

In Management’s and legal advisors’ opinion, there are sound legal grounds to sustain the Company’s tax positions; as a result, Management expects to obtain favorable results on these processes and any additional tax assessment would not be significant to the financial statements.

For the periods pending of examination, and due to the many possible interpretations of current legislation, it is not possible to determine whether or not future reviews will result in tax liabilities for the Company. In the event that additional taxes are payable, including interest and surcharges, as a result of the Tax Authority reviews, they will be charged to expense in the period assessed. However, in Management’s and legal advisors’ opinion, any additional tax assessment would not be significant to the financial statements.

| (e) | SUNAT, the Peruvian tax authority, has assessed mining royalties on materials processed by the Company´s concentrator, which commenced operations in late 2006. These assessments cover the period December 2006 to December 2007 and the years 2008 and 2009. In July 2013, the Peruvian Tax Tribunal issued two decisions affirming assessments for the period December 2006 through December 2008. Decisions by the Tax Tribunal ended the administrative stage of the appeal procedures for these assessments.

In September 2013, the Company filed judiciary appeals related to the assessments because the Company believes that its 1998 stability agreement exempted all minerals extracted from its mining concessions from royalties, irrespective of the method used for processing those minerals. With respect to the judiciary appeal related to the assessment for the year 2008, on December 17, 2014, the Eighteenth Contentious Administrative Court rendered its decision upholding the Company’s position and nullifying SUNAT’s assessment and the Tax Tribunal´s resolution (S/106.4 million Soles). In December 2014, SUNAT and the Tax Court appealed this decision. The court’s position also invalidates all penalties and interest assessed by SUNAT for that period (S/139.7 million Soles). On January 29, 2016, the 6th Superior Justice Court nullified the decision of the Eighteenth Contentious Administrative Court. Cerro Verde will appeal the decision to the Supreme Court.

| F-187 |

Notes to the financial statements (continued)

On October 1, 2013, SUNAT served the Company a demand for payment totaling S/492 million (approximately US$144 million based on December 31, 2015 exchange rates, including interest and penalties of US$85 million) based on the Tax Tribunal’s decisions for the period December 2006 to December 2008. As permitted by law, the Company requested, and was granted, an installment payment program that deferred payment for six months and thereafter satisfies the amount via 66 equal monthly payments. As of December 31, 2015, the Company has made payments totaling S/219 million (US$64 million based on December 31, 2015, exchange rates) under the installment program, which are presented in the long term portion of Other non- financial assets in the statement of financial position (see Note 7). Based on the results rendered by the Eighteenth Contentious Administrative Court as is described in the previous paragraph, the Company requested an injunction that was accepted by the Judiciary and implied a modification of the installment program excluding the 2008 portion through SUNAT´s resolution notified to the Company on October 29, 2015.

In July 2013, a hearing on SUNAT's assessment for 2009 was held, but no decision has been issued by the Tax Tribunal for that year. As of December 31, 2015, the amount of the assessment, including interest and penalties, for the year 2009 was S/247 million (approximately US$72 million based on December 31, 2015, exchange rates). As of December 31, 2015, the Company estimates that the total exposure associated with mining royalties for the period from December 2006 to December 2013, including accumulated interest and penalties amounted to approximately US$500 million at December 31, 2015 exchange rates.

As of December 31, 2015, no amounts were accrued for these assessments or for the amounts paid under the installment payment program because management and its external legal advisors believe the Company’s 1998 stability agreement exempted it from these royalties and believes that the resolution will be favorable to the Company and any payments should be recoverable.

| (f) | The Company has also received assessments from SUNAT for additional taxes (other than the mining royalty explained in (e) above), including penalties and interest. The Company has filed or will file objections to the assessments because it believes it has properly determined and paid its taxes. A summary of these assessments follows:

Year |  | Taxes |  |  | Penalty and Interest |  |  | Total |
|  | US$(000) |  |  | US$(000) |  |  | US$(000) |
2002 – 2005 |  |  | 16,037 |  |  |  | 52,800 |  |  |  | 68,837 |
2006 |  |  | 6,545 |  |  |  | 47,662 |  |  |  | 54,207 |

|  |  | 187,215 |  |  |  | 268,362 |  |  |  | 455,577 |

As of December 31, 2015, the Company has paid US$180,741,000, (included “Non-financial – long term” in the statement of financial position) on these disputed tax assessments, which it believes is collectible. No amounts have been accrued for these assessments.

| 21. | Commitments and contingencies

Commitments

| (a) | Environmental matters -

The Company’s exploration activities are subject to environmental protection standards. In order to comply with these standards, the Company has obtained the approval for the Environment Adequacy Program (“PAMA”) and of the Environmental Impact Studies (EIA), required for the operation of Cerro Verde’s production unit.

On October 14, 2003, Law No. 28090 was enacted, which regulates the commitments and procedures that entities involved in mining activities must follow in order to prepare, file and implement a mine site closing plan, as well as the respective environmental guarantees that assure compliance with the plan in accordance with protection, conservation and restoration of the environment. On August 15, 2005, the regulations regarding this law were approved. During 2006, in compliance with the mentioned Law, the Company completed the closing plans for its mine site. On October 5, 2009 the MEM issued Resolution No. 302-2009 MEM – AAA, approving the mine closure plan of the Company.

On November 20, 2013 according to what is established by Law, the Company presented to the Ministry of Energy and Mines an updated mine closure plan, by means of which the Company updated its mine closure budget.

The estimate of remediation and mine closing costs is based on studies prepared by independent consultants, who comply with the current environmental regulations. This provision corresponds mainly to the activities to be performed in order to restore the areas affected by mining activities. The main tasks to be performed include ground removal, revegetation labor and dismantling of plant and equipment.

The Company believes that this liability is sufficient to meet the current environmental protection laws approved by the Ministry of Energy and Mines. See note 13(b).

| (b) | Construction of the Waste Water Treatment Plant

During 2011, the Company completed the feasibility study for a major expansion of its Production Unit Cerro Verde (hereinafter “the Expansion”) which includes, among others, the expansion and improvements of facilities and mining process, flotation and leaching facilities, as well as expanding them to build a concentrator, a tailings dam and an additional leaching platform (see note 1(b)). As a result, the Company determined that the project will require the use of additional water resources apart from those currently used in the operations.

To carry out this investment in its production unit, the Company agreed with the authorities of Arequipa and SEDAPAR (Arequipa Sanitation Service), within the framework of the expansion, to develop and finance the engineering, construction and operation during the first two years of the Waste Water Treatment Plant (WWTP) and all its components, the same that will be used as a water source for expanded operations, supplementing the existing water resources to support the expansion.

| F-192 |

Notes to the financial statements (continued)

The Company is responsible for the operation and maintenance cost of the waste water treatment plant (the plant), the drive line to the plant and the effluent discharge line. The Company will perform the operation and maintenance of the plant until the earlier of:

| (i) | A new legal framework grant commercialization of the residual water treated or for the water treatment service by the companies that provide sanitation services, and both parties agrees on the amount to be paid by the Company to SEDAPAR;

| (ii) | Establishment of a fee payment, compensation or other right for the water re-use and/or water treatment under the satisfaction of both parties; or

| (iii) | Expiration of the agreement or its extensions.

In August 2013, the Ministry of Housing, Construction and Sanitation approved the environmental and social impact assessment of the waste water treatment plant.

As of December 31, 2015, the construction of the waste water treatment plant was completed with a total investment of S/1,300 million Soles (US$382 million based at December 31, 2015 exchange rate).

In addition to allowing for the viability of the Company’s production unit expansion project, the waste water treatment plant will also benefit the population of Arequipa as it will help to decontaminate the waters of the Rio Chili, and improve the quality of the agricultural products and the environment in general. The waste water treatment plant is expected to start full operations in early 2016.

| (c) | Letter of guarantees –

During years 2015 and 2014, the Company signed letters of guarantee with Banco de Credito de Peru, Scotiabank and BBVA Banco Continental as follows:

Notes to the financial statements (continued)

| 25. | Financial risk management

The Company’s activities are exposed to different financial risks, the main risks that could adversely affect the Company’s financial assets and liabilities or future cash flows are: the risk arising from changes in market prices of minerals, interest rate risk, liquidity risk, credit risk and capital risk. The Company’s financial risk management program focuses on mitigating potential adverse effects on its financial performance.

Management knows the conditions prevailing in the market and based on its knowledge and experience, reviews and manages the risks which are summarized below. Board of Directors reviews and approves the policies to manage each of these risks.

| (a) | Market risk -

Commodity price risk -

The international price of copper has a significant impact on the Company’s operating results. The price of copper has fluctuated historically and is affected by numerous factors beyond the Company’s control. The Company manages this risk through the use of sales commitments with customers. The Company does not hedge its exposure to price fluctuation.

Embedded derivative – As described in note 2.2 (b), the Company has price risk through its provisionally priced sales contracts, which provide final pricing in a specified future month (generally three months from the shipment date) based primarily on quoted LME monthly average prices. The Company receives market prices based on prices in the specified future period, which results in price fluctuations recorded through revenues until the date of settlement. The Company records revenues and commercial invoices at the time of shipment, based on the current LME prices, which results in an embedded derivative on the provisionally priced contracts that are adjusted to fair value through revenues each period, using the period-end forward prices, until the date of final pricing. To the extent that final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease in revenues is recorded at each reporting period until the date of final pricing. See note 24.

The table below summarizes the effect on profit before income tax caused by changes in the copper price. This analysis is based on the assumption that the copper price has increased or decreased by 10% while all other variables are held constant. The 2015 positive scenario uses prices between US$/pound 2.347 to US$/ pound 2.351 (US$/pound 3.140 to US$/pound 3.170 in the year 2014 and US$/pound 3.660 to US$/pound 3.680 in the year 2013); whereas the negative scenario uses prices between US$/pound 1.920 to US$/pound 1.924 (US$/pound 2.570 to 2.590 in the year 2014 and US$/pound 2.990 to US$3.010 in the year 2013).

Exchange rate risk -

As described in note 2.2(a), the Company’s financial statements are presented in US dollars, which is the functional and presentation currency of the Company. The Company exchange-rate risk arises mainly from deposits, taxes, salaries and other accounts payable in currencies other than the US dollar, mainly Soles.

For the year ended December 31, 2015, the Company recorded net foreign exchange losses totaling US$76 million composed by a loss of US$84 million associated with income tax, VAT credits and payments related to the Company’s royalty installment program, which is offset by income of US$8 million from exchange difference derived from other items in the statement of financial position (net income of US$2.3 million in 2014 and net loss of US$ 1.9 million in 2013).

| (b) | Liquidity risk -

Liquidity risk arises from situations in which cash might not be available to pay obligations when they become due at a fair cost. The Company maintains adequate liquidity by properly managing the maturities of assets and liabilities in such way that allows the Company to maintain a structural liquidity position (cash available) enabling it to meet liquidity requirements properly. The Company sells cathode and copper and molybdenum concentrates to recognized companies in the mining sector worldwide. In addition, the Company currently has the possibility to obtain funds from financial institutions and its partners if it is required to meet its contractual obligations.

Notes to the financial statements (continued)

| (c) | Credit Risk -

The Company’s exposure to credit risk arises from a customer’s inability to pay amounts in full when they are due and the failure of third parties in transactions of cash and cash equivalent transactions, which is limited to balances deposited in banks and financial institutions and for trade accounts receivable at the date of the statement of financial position. To manage this risk, the Company has an established treasury policy, which only allows the deposit of surplus funds in highly rated institutions, by establishing conservative credit policies and through a constant evaluation of market conditions. Consequently, the Company does not expect to incur in losses on accounts involving potential credit risks.

The concentration of credit risk also exists when economic changes occur, in industry or geography that affects third parties in the same way. The Company’s customer portfolio is primarily concentrated in three customers, which are related companies with solid financial structures.

The credit risk is limited to the book value of financial assets on the statement of financial position date, which consists mainly of cash and cash equivalents, trade accounts receivable from third parties and trade accounts receivable from related parties. The Company does not use derivative instruments to hedge its exposure to credit risk.

| (d) | Capital risk -

The objective is to safeguard the Company’s ability to continue as a going concern in order to provide returns for shareholders and benefits for stakeholders and maintain an optimal structure that would reduce the cost of capital.

The Company manages its capital structure and makes adjustments to it, in light of changes in economic market conditions. To maintain or adjust the capital structure, the Company controls dividend payments to shareholders, the return of capital to shareholders and the issue of new shares. No changes were made in the objectives, policies or processes during the years ended December 31, 2015, 2014 and 2013.

| 26. | Hierarchy and fair value of financial instruments

Hierarchy:

As of December 31, 2015 and 2014, the only financial asset carried at fair value is the embedded derivative, which is generated by the sale of copper and measured at fair value based on copper prices. The value of this embedded derivative as of December 31, 2015 was a liability of US$18,847,000 (liability US$26,782,000 as of December 31, 2014). This embedded derivative is categorized within Level 2 of the hierarchy. The fair value of embedded derivatives is determined using valuation techniques using information directly observable in the market (forward prices of metals).

Fair value:

Financial instruments whose fair value is similar to their book value –

For financial assets and liabilities which are liquid or have short-term maturity (less than three months), such as cash and cash equivalent, accounts receivable, other accounts receivable, accounts payable, other accounts payable, and other current liabilities, it is estimated that their book value is similar to their fair value.

Financial instruments at fixed and variable rates –

Financial assets and liabilities with fixed or variable rates are recorded at amortized cost and fair value is determined by comparing the market interest rates at the time of their initial recognition to the current market rates with regard to similar financial instruments.

Based on the foregoing, there are no significant differences between book value and fair value of financial instruments (assets and liabilities) as of December 31, 2015 and 2014.

| 27. | Mineral reserves (unaudited)

As of December 31, 2015 and 2014, the Company’s proven and probable copper mineral reserves were:

| 28. | Summary of significant differences between accounting principles followed by the Company and U.S. generally accepted accounting principles

The Company’s financial statements have been prepared in accordance with International Financial Reporting Standards which differs in certain respects from U.S. GAAP. The effects of these differences are reflected in Note 29 and are principally related to the items discussed in the following paragraphs:

| (a) | Stripping Cost – IFRIC 20

Under IFRS, the stripping cost of production that is necessary to produce the inventory is recorded as cost of production, while the one that allows access to additional amounts of reserves to be exploited in future periods are capitalized and amortized based on proved and probable reserves of each ore body (component) identified in the open pit.

Under U.S. GAAP, the costs of clearing removal (stripping cost of production) incurred during the production stage are recorded as part of the production cost of inventories.

| (b) | Inventories

Under IFRS, the cost inventory includes: (i) the depreciation and amortization expense, (ii) the amortization of production-stripping costs and (iii) workers´ profit participation. Under U.S. GAAP the cost inventory excludes these items.

| (c) | Deferred workers’ profit participation

Under IFRS, the workers’ profit participation is calculated based on the Company’s taxable income and is recorded as an employee benefit (cost of production or administrative expense, depending on the function of the workers).

Under U.S. GAAP, the workers’ profit sharing is treated in a similar way as income tax since both are calculated based on the Company’s taxable income. Therefore, the Company calculates a deferred workers’ profit participation resulting from the taxable and deductible temporary differences.

| (d) | Deferred income tax –

The differences between U.S. GAAP and IFRS are re-measurements that lead to different temporary differences. According to the accounting policies in Note 2.2 (l), the Company has to account for such differences.

| 29. | Reconciliation between net income and shareholders' equity determined under IFRS and U.S. GAAP

The following is a summary of the main adjustments to net income for the years ended December 31, 2015, 2014 and 2013 and to shareholders' equity as of December 31, 2015, 2014 and 2013 that would be required if U.S. GAAP had been applied instead of IFRS in the financial statements:

| 30. | New U.S. GAAP Accounting Pronouncements

Recently Issued Accounting Pronouncements -

Inventory -

In July 2015, ASU guidance was issued related to inventory simplifying the subsequent measurement of inventories by replacing the lower of cost or market test with a lower of cost and net realizable value test. The update is effective in fiscal years, including interim periods, beginning after December 15, 2016, and early adoption is permitted. The Company is currently evaluating this guidance and the impact it will have on net equity or net results.

Revenue recognition –

In May 2014, ASU guidance was issued related to revenue from contracts with customers. The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition. In August 2015, the effective date was deferred to reporting periods, including interim periods, beginning after December 15, 2017, and will be applied retrospectively. Early adoption is not permitted. The Company is currently evaluating this guidance and the impact it will have on net equity or net results.
