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/.,” “Nuevo Sol” or “Nuevos Soles” are to Peruvian Nuevos 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 metric tons; references to a value denominated in “DT” refer to dry metric 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 changed the accounting principles governing the presentation of our consolidated financial statements from Peruvian GAAP to International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or 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 accounting principles generally accepted in the United States of America, or U.S. GAAP, and IFRS as issued by the IASB, respectively.

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 percent for the years ended December 31, 2011, 2012 and 2013. As of December 31, 2011, our equity interest in Cerro Verde was 19.35 percent and as of December 31, 2012 and 2013 our equity interest was 19.58 percent.

Forward-Looking Statements

Certain statements contained in this Annual Report are “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.

1

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:

| · | 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, is dependent upon 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. There can be no assurance 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.

Our revenues are derived primarily from the sale of ore concentrates containing gold and silver; 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 the overall demand for and worldwide supply of gold, silver, copper and other metals, the availability and price of competing commodities, international economic trends, currency exchange fluctuations, expectations of inflation, actions of commodity markets participants, consumption and demand patterns and political events in major producing countries. 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 29 to the Financial Statements. For information on gold and silver prices for each of the years in the five-year period ended December 31, 2013, see “Item 4. Information on the Company – Buenaventura – B. Business Overview –Sales of Metal Concentrates.”

On December 31, 2013 and March 31, 2014, the morning fixing price for gold on the London Bullion Market was US$1,221.59 per ounce and US$1,336.56 per ounce, respectively. On December 31, 2013 and March 31, 2014, the afternoon fixing spot price of silver on the London market, or London Spot, was US$19.61 per ounce and US$20.74 per ounce, respectively. On December 31, 2013 and March 31, 2014, the London Metal Exchange Settlement price for copper was US$7,202.95, per metric ton and US$6,667.83, per metric ton, respectively.

The world market prices of gold, silver and copper have historically fluctuated widely and there is no assurance that the prices for these metals will continue to maintain their current high historical levels. We cannot predict whether metal prices will rise or fall in the future. A 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.

In addition, sustained low gold, silver or copper prices could reduce revenues further through production declines due to cessation of the mining of deposits, or portions of deposits, that have become uneconomic at the then-prevailing market price; reduce or eliminate the profit that we currently expect from reserves; halt or delay the development of new projects; reduce funds available for exploration; and reduce existing reserves by removing ores from reserves that can no longer be economically processed at prevailing prices. Such declines in price and/or reductions in operations could also 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, or 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.

8

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.” There can be no assurance 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, there can be no assurance 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. There can be no assurance 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, no assurance can be given that our or Yanacocha’s exploration programs will result in the expansion or replacement of current production with new proven and probable ore reserves.

9

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.”

10

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. Based on the current recovery rate and estimated gold production levels in 2013, Yanacocha’s proven and probable reserves as of December 31, 2013 will be depleted by 2019 unless Yanacocha continues to add to its reserves. As a result, 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, 2013.

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.

11

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, Coimolache, Yanacocha and Cerro Verde have all experienced strikes or other labor-related work stoppages in the past. In 2013 we experienced strikes in four of our mines. Julcani and Recuperada were affected by a simultaneous strike that lasted 20 days between April and May. Uchucchacua had a total of 15 days of work stoppage during 2013, most of them related to a worker’s union of one of our contractors. Orcopampa was also affected by two strikes, one called by the National Federation of Mining Workers, which lasted one day, and another regarding proper ventilation in our mines, which lasted for 17 days.

As of December 31, 2013, unions represented approximately 43 percent of the employees of our mining companies. Although we consider our relations 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 and Yanacocha’s operations are subject to political and social risks.

Our and Yanacocha’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. There can be no assurance that these 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.

12

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 in the event that 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, or 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, 2013, we owned a 43.65 percent partnership interest in Yanacocha and a 19.58 percent 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 percent 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 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.

13

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, or 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 prior to 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. Yanacocha expects to receive the permits to commence construction of the El Perol reservoir in 2014. 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.”

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.

14

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, we are unable to predict whether the central government will continue to take similar positions in the future. Furthermore, the regional government in Cajamarca actively opposed the Conga project in 2012 and continues to reject the viability of its development. Regional presidential elections will take place in October 2014. 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 Nuevo 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, or IPC, and published by Instituto Nacional de Estadística e Informática, or INEI, has fallen from a high of 7,649.7 percent in 1990 to 2.86 percent in 2013. 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 Nuevo 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, 2013 were US$65.7 billion as compared to US$64.0 billion at December 31, 2012. 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.

The market for securities issued by Peruvian companies is influenced by economic and market conditions in Peru and, to varying degrees, market conditions in other Latin American and emerging market countries. Within Peru, news of Ollanta Humala’s June 5, 2011 victory in the presidential election was followed by a 12 percent decline in both the Lima stock exchange (Bolsa de Valores de Lima, or BVL) and BVL’s mining sub-index the following day. The price of our American Depositary Receipts, or ADRs, fell 15 percent. A number of banking analysts lowered their recommendations on Peruvian mining companies following the election as a result of concerns of higher taxes and delays in mining projects.

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.

15

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. Prior to 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.

The aggregate percentage of the economic interest of our outstanding share capital controlled by Elsa Ganoza Benavides (spouse of the late Alberto Benavides de la Quintana, our founder and former Chairman and Chief Executive Officer), and held by certain members of her immediate and extended family and their spouses, or the Benavides Family, as of March 31, 2014 was 27.22 percent (including outstanding Common Shares and Investment Shares). 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.

16

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 Peruana, 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 percent 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.

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 (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. 5-11-419-2500. Our Internet website address is 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. In 2013, gold, silver, copper and other metals accounted for 49 percent, 28 percent, 14 percent and 9 percent, respectively, of our revenues from our consolidated subsidiaries.

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, Minera Gold Fields Peru S.A., or Gold Fields, and Southern Copper Corporation, or SCC. 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 2013, we spent US$32.8 million on “greenfield” and US$167.1 million on “brownfield” exploration-related investments in Peru. Our “greenfield” investments mainly focused on the following exploration projects: Surichata, Colquemayo, Paco Paco, Trapiche and El Brocal. Our “brownfield” investments were mainly focused in the Orcopampa, Uchucchacua, Mallay, Recuperada, Tambomayo and La Zanja. In 2013, we financed our exploration program with internal funds.

In 2014, we intend to invest approximately US$70 to US$80 million in brownfield exploration projects. In 2014, we expect to invest approximately US$35 to US$40 million, mainly in the following greenfield exploration projects: El Brocal, Colquemayo, Pisacalla, Livitaca and Palla Palla, 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 subsidiaries) and by category of expenditure:

We mainly financed our capital expenditures in 2012 and 2013 with internally-generated funds. We partially funded the El Brocal Expansion and the construction of the Huanza hydroelectric power plant with leasing facilities of US$234.4 million (US$115.4 and US$119.0 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$270 to US$290 million for capital expenditures for 2014. 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.

Data in this table reflect 100% of production El Brocal and La Zanja.

Exploration

We view exploration as our primary means of generating growth value for shareholders and typically maintain a portfolio of active exploration projects at various stages of exploration for mineral resources in Peru. We invested approximately US$95.5 million in exploration for Mineralized Material Not in Reserve (“NRM”) during 2013, including exploration related to El Brocal, Paco Paco, Colquemayo, Surichata and Trapiche projects.

In 2014, we expect to invest approximately US$100 to US$120 million in greenfield exploration and brownfield exploration activities. Exploration programs at our principal operating mines are not included in our exploration budget and are accounted for as part of the operating costs for each mine. Exploration expenditures in greenfield and brownfield projects include all of the costs associated with geologists, contractors, engineering, drilling equipment, metallurgical testing and environmental, social, engineering and economic feasibility studies. Our exploration team prepares programs and budgets for individual projects each year and we allocate, subject to board approval, the proper amount to finance each particular exploration activity considered worthwhile. In light of the nature of mining exploration and in order to maintain flexibility to take advantage of opportunities, we allocate budgeted amounts by property or project only in the case of high geological expectation as decided by management. We also allocate non-budgeted amounts over the course of the year to new projects based on factual results, our needs and our geologists’ periodic evaluations and opinions regarding the progress of each opportunity and its potential for further exploration of minerals.

An integral part of our exploration program is the participation in mining exploration agreements with affiliates of experienced mining companies, including Newmont Peru S.R.L., Southern Copper Corporation, Gold Fields La Cima and Minera Gold Fields Peru S.A. The benefits of these joint exploration projects include greater investment in the exploration of our mining rights from the funds contributed by the partners, access to the assets of the partners 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 designated operator, an equity participant, the manager or a combination of these and other functions.

The following table lists our principal greenfield exploration projects, 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, 2012 and 2013.

The following is a brief summary of current exploration activities conducted by us 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, 2013:

Greenfield Exploration Projects

Chucapaca. The Chucapaca project is a gold-copper-silver greenfield exploration project wholly-owned by Canteras del Hallazgo S.A.C., or CDH, which is 51 percent-owned by Minera Gold Fields Peru S.A. and 49 percent-owned by us. The project is located in the Moquegua region in southern Peru. Our preliminary exploration activities at the Chucapaca project have included geophysical magnetic surveys, induced polarization surveys and diamond drilling, which resulted in the discovery of gold mineralization. During 2014, CDH intends to conduct infill diamond drilling in the underground areas. As of December 31, 2013, we estimated NRM for the Chucapaca project to be 9.1 million tons, with an average grade of 5.5 grams per ton of gold.

Trapiche. The Trapiche project is wholly-owned by us and encompasses 6,600 hectares of mining concessions owned by us, with porphyry copper and skarn mineralization in the Apurimac region. The Apurimac region is part of a mineralized belt known as the Abancay Batholith, where several iron, copper and gold deposits have been identified. Our exploration activities at the Trapiche project have included diamond drilling and magnetic and induced polarization surveys. In 2011, we negotiated and obtained a 30-year lease with the Mollebamba community for surface rights to conduct infill and additional diamond drilling and other engineering studies. We created a wholly-owned subsidiary to operate the Trapiche project, El Molle Verde S.A.C., and we leased all mining properties to this subsidiary. In 2013, we invested US$2.59 million to conduct diamond drilling, including exploration, metallurgical and hydrogeological drilling, and a scoping study. As of December 31, 2013, we estimated NRM for the Trapiche project to be 726 million tons, with an average grade of 0.40 percent of copper, 0.01 percent of molybdenum and 3.2 grams per ton of silver into the Trapiche porphyry and Millocucho skarn. In 2014, we plan to invest from US$25 to US$30 million to conduct diamond drilling and to complete a scoping study.

Paco Paco. The Paco Paco project encompasses 1,633 hectares of mining concessions leased in the Arequipa region in southern Peru, 5 kilometers north of the Caylloma silver mine in the Caylloma mining district. The project consists of 17 kilometers of veins within an acid-sulphate system. During 2013, we invested US$1.0 million to conduct diamond drilling. We do not plan to conduct any further work on this project. We terminated the lease for this property in December 2013.

Surichata. The Surichata project is located in the Puno region of southern Peru and consists of 700 hectares of mining concessions. The Surichata project shows evidence of epithermal silver enriched polymetallic veins. In 2013, we invested US$1.7 million to conduct diamond drilling. We found a small resource deposit of lead and zinc. We do not plan to conduct any further work on this project. In 2014, we plan to sell or transfer this project to a third-party operator.

Colquemayo. The Colquemayo project is wholly-owned by us and encompasses 6,300 hectares of mining concessions located in the Moquegua region in southern Peru, 70 kilometers southwest of the Chucapaca project. The project is located in tertiary volcanic rocks covered by younger volcanic events. The high sulfidation alteration system covers an area of 40 square kilometers. During 2013, we invested US$0.6 million in environmental remediation and social agreements. In 2014, we plan to invest up to US$1 million in order to conduct 1,780 meters of diamond drilling.

Pisaccalla. Pisaccalla-Accocruz-Ccelloccasa is a new project that is wholly-owned by us which encompasses 1,900 hectares of mining concessions located in the Ayacucho region in southern Peru, 35 kilometers northwest of our Breapampa gold mine and 5 kilometers northwest of the Apumayo gold mine. The project shows evidence of a potential gold target in veins in a low sulphidation epithermal system. In 2014, we plan to invest US$1.5 to US$2.5 million to conduct 6,600 meters of diamond drilling.

Livitaca. Livitaca is a new project located in the Cusco region in southern Peru, 8 kilometers north of the Constancia copper project owned by Hudbay. The project encompasses 9,096 hectares of mining concessions leased to Cía. de Minas Cerro Hablador S.A.C, our newly formed wholly-owned subsidiary, and Corporación Aceros Arequipa S.A. The project is an iron skarn with surrounding gold and copper mineralization. In 2014, we plan to invest US$1.0 to US$2.0 million to both conduct preliminary field work and obtain social and environmental permits for a drilling campaign in 2015.

24

Palla Palla. Palla Palla is a new project located in Ayacucho region, 25 kilometers north of our Breapampa gold mine. The project encompasses 6,694 hectares of mining concessions in the process of being leased to our newly-formed wholly-owned subsidiary and Cía. de Minas Caudalosa S.A. The project shows evidence of a potential gold target in a high sulphidation epithermal system. In 2014, we plan to invest US$2.0 to US$3.0 million in order to conduct 5,200 meters of drilling.

Brownfield Exploration Projects

Uchucchacua. The Uchucchacua brownfield exploration project currently encompasses 804 hectares of our mining concessions. We are currently focusing our exploration efforts on the Yumpag project, which is located 4 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 2013, we invested US$3.0 million and completed 980 meters of exploration tunnels, conducted 1,202 meters of diamond drilling and conducted metallurgical tests. As of December 31, 2013, we estimated NRM of 0.21 tons, with 350.03 grams per ton of silver and 35.1 percent manganese. In 2014, we expect to invest US$1.5 to US$2.5 million in order to both complete 530 additional meters of exploration tunnels and conduct 1,800 meters of diamond drilling.

Mallay. Our exploration efforts in Mallay are focused in the Chanca project, which is located in the province of Oyon, department of Lima, about 15 kilometers northwest of the Mallay mine. During 2013, we invested US$7.0 million and completed 5,437 meters of diamond drilling and 4,329 meters of exploration tunnels, focusing mainly on the Santo Toribio vein. As of December 31, 2013, we had estimated NRM of 0.12 tons, with 424.8 grams per ton of silver. In 2014, we will not conduct any explorations.

Orcopampa. The Orcopampa brownfield exploration projects cover a total of 12,285 hectares of our mining concessions including properties to which we have access as a result of agreements with SCC (in respect of Pucay) and Minera Ares (in respect of Parihuanas). We are currently focusing our exploration efforts on the Parihuanas, Aseruta-Mulañan, and Pucay projects.

The Parihuanas project, a joint venture with Minera Ares, is located 24 kilometers northeast of Chipmo and consists of 5,898 hectares. During 2013, we invested US$4.46 million to construct drifts for exploration and diamond drilling. As of December 31, 2013, we had estimated NRM of 0.24 tons, with 15.94 ounces per ton of silver. In 2014, we expect to invest US$5.49 million to complete 1,350 meters of exploration tunnels and 6,000 meters of diamond drilling.

The Aseruta-Mulañan project is located 8 kilometers southeast of the town of Orcopampa. It consists of a system of epithermal veins with mainly silver content. During 2013, we invested US$1.71 million and completed diamond drilling with positive results which encouraged us to continue the explorations. In 2014, we expect to invest US$1.57 million to complete 6,100 meters of diamond drilling.

The Pucay project is located 3.5 kilometers southwest of the Chipmo mine. In 2014, we plan to invest US$0.77 million to develop an 1,800-meter diamond drilling program and to conduct geological mapping and sampling.

Recuperda. The Recuperada brownfield exploration project currently encompasses 1,764 hectares of mining concessions and is wholly-owned and operated by us. During 2013, we invested US$6.59 million to perform geological surveys, outcrop sampling and diamond drilling. In 2014, we expect to invest US$1.52 million, mainly on diamond drilling in the Patara project.

The Alejandra- La Zanja. The Alejandra – La Zanja exploration project is operated by us and currently encompasses 999 hectares of mining concessions. During 2013, we invested US$1.24 million to perform diamond drilling. As of December 31, 2013, we had an estimated NRM of 0.7 tons, with 15.43 grams per ton of gold and 240.69 grams per ton of silver. In 2014, we expect to invest US$7.8 million to construct drifts for exploration and diamond drilling.

25

Tambomayo. The Tambomayo project is wholly-owned and operated by us. It is located 20 kilometers east of the Paula mine and encompasses a total of 3,500 hectares. The project is believed to be a low sulfidation epithermal deposit with significant gold and silver mineralization in a vein system. As of December 31, 2013, we had an estimated NRM of 1.6 tons, with 13.58 grams per ton of gold, 285.26 grams per ton of silver, 2.1 percent lead and 3.0 percent zinc. In 2014, we will be focusing on the Blanquita, Mayra and Gaby projects. We plan to invest US$1.39 million to develop a 3,000-meter diamond drilling program in the Blanquita project and geological mapping and sampling at the Mayra and Gaby projects. The project is currently in its development phase.

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, or 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 prior to, 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 |

________________

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 2013, 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 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.”

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.

From April to December 2014, El Brocal has outstanding hedging commitments amounting to 6,700 metric tons of copper at an average fixed price of US$7,209 per ton.

El Brocal’s hedge is classified as a cash 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.

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 Ministry of Mines, or MEM.

28

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, or INGEMMET.

Mining concessions granted since October 2008 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.

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 prior to 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.

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. In order to grant a mining concession in an urban or urban expansion area, the MEM is required to receive the approval of the council of the applicable provincial municipality. Mining concessions in urban areas are granted for 10-year terms, which may be renewed by the MEM subject to the approval of municipal authorities.

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, or 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.

With respect to employee safety and employer liability, Law No. 28964 has been replaced by Law No. 29783 and related matters are audited by the Ministerio de Trabajo y Promoción del Empleo. Law No. 29783 establishes rules designed to prevent employee safety risks and allocate liabilities in relation to such risks. This legislation entitles labor inspectors to inspect commercial facilities and, under certain circumstances, suspend operations.

29

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 MINAM has issued regulations mandating environmental standards for the mining industry and reviews and approves environmental studies for mining operations. OEFA has the authority to inspect mining operations and fine companies that fail to comply with prescribed environmental standards.

The MEM has issued regulations that establish maximum permissible levels of (i) emissions of liquid effluents and (ii) elements and compounds present in gaseous emissions resulting from the mining activities. Generally, holders of mining rights and processing plants that were in operation prior to May 1993 are required to comply with maximum permissible levels within 10 years. In the interim, mining operators are required to prepare Environmental Adaptation and Management Programs, or PAMAs, that set forth plans to ensure compliance with more stringent maximum permissible levels. 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 maximum permissible levels for liquid effluents. The deadline was August 31, 2012. Buenaventura and its associated companies submitted their plans. We expect that we will be required to implement these plans and be in compliance with the new maximum permissible levels for liquid effluents and water quality standards by 2014 and 2015, respectively.

In addition, each mining company that initiated operations prior to May 1993 was required to file a Preliminary Environmental Evaluation, or EVAP, for each of its mining units to disclose any pollution problems in its operations and, thereafter, to submit a follow-up PAMA aimed at implementing measures in order 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 no less than 1 percent of their annual sales to redress the problems identified in their EVAPs and contemplated in their PAMAs.

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. Projects existing at that time had twelve months to adapt to the Standards. Suplementary provisions for the application of the Standards have been approved through Supreme Decree No. 002-2014-MINAM effective since March 25, 2014.

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 maximum permissible levels for liquid effluents from the initiation of their operations.

EISs for capacity expansion at the Orcopampa, Uchucchacua and Antapite mines were approved in 2004, 2006 and 2008, respectively.

The MEM approved the EISs for the Huancarama-Chipmo-Poracota and La Zanja transmission lines and their substations in 2006 and 2008, respectively. This connection to the national grid should result in lower energy costs.

In May 2008, the Environmental Ministry of Peru was established by legislative decree. The principal functions of the Environmental Ministry 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 2009, the MEM approved the EISs for the La Zanja, Mallay, Tantahuatay and Esperanza projects. In 2010, the MEM approved the EISs for the Angélica Rublo Chico project. In 2011, the MEM approved the EISs for our Orcopampa and Breampampa projects. The MEM approved the modified EIS for the Mallay mine and the second modified EIS for the Shila cyanidation circuit in 2012.

In 2012, Peru enacted Supreme Decree N° 020-2012, which requires the approval of the Mining Department of the Ministry of Energy and Mines prior to the starting and re-starting of exploration, development, preparation and exploitation activities.

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$3.8 million. See Note 13 of the Financial Statements.

30

In 2012, Peru enacted Supreme Decree N° 020-2012-EM, which added Chapter XVII to the Mining Proceedings Regulations approved by Supreme Decree N° 018-92-EM. The new provisions require all activities to start and re-start exploration, development, preparation and exploitation to obtain the approval of the Mining Department of the Ministry of Energy and Mines or of the relevant Regional Government. With regard to water regulation, all Peruvian mining companies were required to submit their updated environmental management plans to comply with water quality standards and the new maximum permissible levels for liquid effluents by August 31, 2012. Buenaventura and its associated companies submitted our plans. We expect that we will be required to implement these plans and be in compliance with the new maximum permissible levels for liquid effluents and water quality standards by 2014 and 2015, respectively.

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 are divided into 2 categories, Category I and Category II. Category I exploration activities are those involving no more than 20 drilling platforms or affecting the environment in an area of no more than 10 hectares, while Category II exploration activities are those involving more than 20 drilling platforms and affecting the environment in an area of more than 10 hectares. For Category I exploration activities, an Environmental Impact Declaration (Declaración de Impacto Ambiental), or EID, is required. For Category II exploration activities, a Semi-detailed Environmental Impact Study (Estudio de Impacto Ambiental), or 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 shall be approved before starting the exploration works. The commitments assumed by mining companies in their EID, EISsd are mandatory; if they are not fulfilled, OEFA has the authority to fine these 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 start 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, MEM enacted DS 028-2008, which establishes the right of every person to participate in the process of making decisions related to the sustainable development of mining activities on government territory. The EID and EISsd require local communities to have an opportunity to actively participate in this process.

The following EIDs and EISsd were approved in 2013:

Investment Promotion Regulations. Supreme Decree 054-2013-PCM was passed in order 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.

31

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 the MEM within one year following approval of an EIS or PAMA; inform the MEM semi-annually of any progress on the conditions established in the Closure Plan; perform the Closure Plan consistent with the schedule approved by the MEM during the life of the concession; and grant an environmental guarantee that covers the estimated amount of the Closure Plan.

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.

We have presented Closure Plans to the MEM for all of our mines and advanced explorations. To date, the MEM 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 follow Mine Closure Plan Updates were approved in 2013:

Poracota |  | Closure Plans |  | N° 409-2013-MEM/AAM |  | 30.10.13

On November 9, 2009 Supreme Decree No. 078-2009-EM became effective, creating additional environmental obligations for the holders of mining concessions. Under this provision, holders of mining concessions that have performed mining activities, including mining exploration, exploitation and processing activities or related activities, without having an Environmental Certification will be required to prepare and perform an Environmental Remediation Plan to cure the environmental impact in the areas in which such activities have been conducted. Environmental Plans may only be filed once mining activities have ceased. The Environmental Remediation Plan will contain a detailed description of all the mining items 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 MEM for the cost of the execution of the measures contained in the Environmental Remediation Plan. Once the Environmental Remediation Plan is performed, the holders of mining concessions 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 the MEM 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 the MEM 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 MEM for all our mining concessions with environmental mining liabilities. To date, the MEM has approved the mining liabilities for Hualchocopa, Lircay, Bella Unión-Pucaray and Chaquelle, and all of these concessions have been closed.

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 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 (CIRA) 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 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 of 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.

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 cap the consultation process at 120 calendar days.

Permits

We believe that our mines and facilities have all necessary material permits. 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 conditions could have a material adverse effect on our financial condition or results of operations.

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, comprehensive automobile liability, all risk property on a replacement basis, including transit risks, business interruption insurance and mining equipment.

33

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 shall be payable either as a specified percentage of operating profit or 1 percent of revenues, whichever is higher. If the mining royalty is calculated as a percentage of operating profit, marginal rates ranging from 1 percent to 12 percent, increasing progressively for companies with higher operating margins, will apply.

Mining companies that are 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 a stabilization agreement, 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 de Minería). The Special Mining Tax is calculated as a percentage of operating profit. Marginal rates range from 2 percent to 8.4 percent, 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 de Minería). The Special Mining Duty is calculated as a percentage of operating profit, with marginal rates ranging from 4 percent to 13.12 percent, increasing progressively for companies with higher operating margins.

Safety

The safety and health of our employees is our highest priority. During 2013, our Corporate Safety and Health Management System, or SHMS, was recertified by Bureau Veritas. The core components of our SHMS are risk assessment, training, hazard identification and task observations.

During 2013, we experienced 148 reportable injuries, 142 lost-time injuries and 6 fatal injuries, as compared to 117 total reportable injuries, 115 lost-time injuries and 2 fatal injuries for the year ended December 31, 2012. 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.

We have implemented several measures in order to prevent fatal accidents, including the appointment of a Safety Director who reports to the Chairman of the Board, a one-day shutdown in every mine site, reinforced participation of all management, full housekeeping at every site, renewed training programs, extensive reporting of substandard conditions, the launch of the “Look-think-plan-do” campaign, management safety tours, making vice presidents responsible for the investigation of fatal accidents in their areas and safety presentations regarding leadership and commitment.

YANACOCHA

A. History and Development of the Company

Founded in Peru in 1992, Yanacocha is the largest gold producer in South America. Yanacocha produced 1,017,259 ounces of gold in 2013. Yanacocha’s operations are located in the Andes Mountains in Northern Peru in the area 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: 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.

Yanacocha continues to develop the Conga project, which is located approximately 24 kilometers northeast of the Yanacocha operating mine in the provinces of Celendin, Cajamarca and Hualgayoc. The project consists of two gold-copper porphyry deposits that are estimated to more than double Yanacocha’s proven and probable reserves. However, since mid-2012, the development of Conga has been based on a “water first” approach, which consists of building the originally planned community water reservoirs prior to resuming any mine development. During 2013, the first of these reservoirs in San Nicolás and associated roads was constructed. Other activities during 2013 related to finalizing the engineering works and accepting delivery of the main equipment purchases. Work to ensure the economic viability as well as the social acceptance of the project continues in parallel with the site reservoir construction activities.

As of December 31, 2013, Yanacocha’s proven and probable reserves (excluding the Conga project’s proven and probable reserves) were estimated to be 5.7 million ounces of gold, representing a 3 percent decrease over Yanacocha’s proven and probable reserves as of December 31, 2012, which were estimated to be 5.9 million ounces of gold. As of December 31, 2013, the Conga project’s proven and probable reserves were estimated to be 12.6 million ounces of gold and 3.3 billion pounds of copper, unchanged from the estimated 2012 gold and copper reserves. As of December 31, 2013, Yanacocha’s total proven and probable reserves (including the Conga project) were estimated to be 18.3 million ounces of gold, representing a 1 percent decrease over Yanacocha’s total proven and probable reserves as of December 31, 2012, which were estimated to be 18.5 million ounces of gold. Yanacocha’s total proven and probable reserves of copper were 3.3 billion pounds as of December 31, 2013.

Proven and probable reserves are based on extensive drilling, sampling, mine modeling and metallurgical testing from which economic feasibility has been 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 2013, Yanacocha produced 1,017,259 ounces of gold, compared to 1,345,992 ounces in 2012. The decrease in gold production in 2013 as compared to 2012 was mainly attributable to lower leach grade placed on leach pads compared to the prior year as well as lower mill grades and recovery.

Silver production was 553,092 ounces in 2012 and 363,274 ounces in 2013. The decrease in silver production in 2013 as compared to 2012 was mainly attributable to lower high-grade silver ounces from the Yanacocha pit being placed on leach pads during 2013.

Yanacocha is owned 51.35 percent by Newmont Mining, through its wholly-owned subsidiary Newmont Second, 43.65 percent by us through our wholly-owned subsidiary Condesa and 5 percent 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 after agreement between the two major shareholders, Newmont Mining and us.

38

Capital Expenditures

Yanacocha’s capital expenditures from its formation in 1992 through 2013 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 and La Quinua mining operations. Yanacocha’s capital expenditures from its formation through December 31, 2013 totaled approximately US$5,733 million, including capital expenditures of US$ 1,094 million in 2011, US$1,148 million in 2012 and US$340 million in 2013.

In 2013, Yanacocha’s principal capital expenditures included US$164 million for engineering, construction and equipment at the Conga project, US$82 million for mine development at El Tapado Oeste, the Western Oxides and the Eastern Oxides deposits, US$21.2 million for equipment components, US$20.7 million for bio-leach studies and plant construction, US$11.8 million to upgrade the Yanacocha Gold Mill, US$9.6 million for water treatment plant studies and construction, US$5.9 million for the construction of the raw water pond at Yanacocha Norte, US$6.2 million for gold mill tailings improvements, US$6.2 million for the standardization of information technology systems, US$3.5 million for Chaquicocha pit development and US$8.9 million for other minor projects.

Yanacocha anticipates that its capital expenditures for 2014 will be approximately US$226.0 million, of which it plans to use approximately US$38.6 million in connection with the construction of the Conga project. The remaining capital expenditure budget has been allocated for investment in current operations and development of future operations.

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: Carachugo, Chaquicocha, Maqui Maqui, San José, 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.

39

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 metric tons, or DMT. 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 percent of the total ounces produced by Yanacocha. In order 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 respectively, 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 currently assaying approximately 52 percent gold and 45 percent 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.”

Electric power for Yanacocha’s operations is currently provided by local power companies via two separate networks from the Cajamarca Norte substation in 60 kilovolts, or kV, and 220 kV, respectively. Yanacocha also maintains diesel generation capacity for emergency requirements, which have an aggregate power generation capacity of 33.75 MW. In addition, Yanacocha has been connected to the Peruvian national electricity grid since the end of 1997. Yanacocha currently receives its supply of electric power through a 220 kV power line originating in Trujillo, which is owned by Buenaventura and has the capacity to provide up to 150 MW to Yanacocha (although current contracted demand is limited to 70 MW). In addition, a 60 kV power line routed through Cajamarca permits Yanacocha to receive up to 10 MW. This power line is used only in emergencies. 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 271,647 hectares covered by 394 mining concessions. Of these 271,647 hectares, SMRL Chaupiloma Dos de Cajamarca holds the mining rights related to 105,634 hectares, covered by 144 mining concessions. Chaupiloma has assigned these mining concessions to Yanacocha pursuant to several assignments of mining rights, each with an initial term of 20 years, which are renewable at Yanacocha’s request for an additional 20-year term.

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. 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.

Exploration expenditures amounted to approximately US$40.0 million and US$20.0 million in 2012 and 2013, respectively. These expenditures have been used to identify deep sulfide mineralization beneath the oxide deposits at Tapado Oeste North, Yanacocha Sur, La Quinua Sur and Cerro Negro, to reevaluate and advance the Chaquicocha Sulfides and Yanacocha Verde projects and to complete additional drilling designed to increase ore grade and resources and continue exploration in the Yanacocha district and surrounding areas. In 2014, exploration efforts will focus on continuing exploration in the Yanacocha district and conducting an exploration program in the Yanacocha concession block outside of the operation district.

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

Yanacocha intends to continue to develop other oxide and sulfide projects and the Conga gold-copper deposit project over the next years, while continuing to explore the remainder of the Yanacocha district along with the adjacent Minas Conga and Solitario mineral holdings. The Conga project currently consists of two gold-copper porphyry deposits that are estimated to more than double Yanacocha’s proven and probable reserves. 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, 2013.

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 EIA independent review were announced on April 20, 2012 and confirmed that our initial 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 its decision to move the project forward on a “water first” approach on June 22, 2012. As a result, investment on the project will be reduced in 2014 from approximately US$119 million to US$79 million, and focus on building water reservoirs, completing the last engineering activities and accepting delivery of the main equipment purchases. Construction of Conga and the implementation of the independent EIA review recommendations will continue provided it can be done in a safe manner with risk-adjusted returns that justify future investment. Should Yanacocha be unable to continue with the current development plan at Conga, mining activities may be reprioritized and capital reallocated to development alternatives which may result in potential accounting impairments.

41

For 2014, Yanacocha estimates expenditures of US$10 million for exploration, The expenditure estimate is exclusive of significant development engineering charges. This budgeted amount will be expended mainly on sulfide development at Yanacocha and an extensive exploration program in district and regional properties that Yanacocha controls.

As of December 31, 2013, the Yanacocha district’s proven and probable reserves (excluding the Conga project’s proven and probable reserves) were estimated to be 5.7 million ounces of gold, a 3 percent decrease from the Yanacocha district’s proven and probable reserves as of December 31, 2012, which were estimated to be 5.9 million ounces of gold. The decrease in reserves of gold was mainly due to mine depletion, and to a lesser extent, metal price decreases, reserve revisions and leach and stockpile inventory changes. As of December 31, 2013, proven and probable gold reserves were calculated using a gold price assumption of $1,300 per ounce.

As of December 31, 2013, the Conga project’s proven and probable reserves were estimated to be 12.6 million ounces of gold and 3.3 billion pounds of copper, unchanged from the 2012 gold and copper reserves.

Transportation and Refining

The doré bars produced by Yanacocha are transported to refineries outside of Peru and, accordingly, 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 prior to 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, 2013, Yanacocha had 2,294 employees. Compensation received by Yanacocha’s employees includes base salary and other non-cash benefits such as a health program and term life insurance. In addition, pursuant to the profit sharing plan mandated by Peruvian labor legislation, employees at Yanacocha are entitled to receive 8 percent of Yanacocha’s annual pre-tax profits, or the Employee Profit Sharing Amount, with 50 percent of such profits to be distributed based on the number of days each employee worked during the preceding year and the remaining 50 percent of such profits to be distributed among the employees based on the aggregate annual salary of each employee.

42

Yanacocha has entered into arrangements with independent contractors that are responsible for the security services and staffing for several operational and administrative areas. As of December 31, 2013, independent contractors employed 4,989 persons who worked at Yanacocha’s operations. In 2004, Yanacocha entered into its first collective bargaining agreement with a union representing certain of its employees, which was created on December 9, 2003. The Department of Industrial Relations meets regularly with union leaders to address labor problems in the organization and to promote the creation of a productive and harmonious labor environment. The parties address their issues through open and transparent dialogue. In 2012, a new union was established, and in 2013 new collective bargaining agreements were signed with both unions for a period of three years (2013-2016).

Social Development

Since its creation, Yanacocha has been focused on its relationship with the community and actively participating in its development.

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 2013 Yanacocha initiated a new community outreach plan known as the “legitimacy approach,” which emphasizes the following: 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 2013, Yanacocha invested a total of US$17.1 million on social matters, of which US$8.0 million (including Conga Project and the Association Los Andes of Cajamarca - ALAC) were invested mainly in promoting farming activities, education and infrastructure related to water supply. Additionally, Yanacocha invested US$9.1 million in the mitigation of mining’s social impact in areas of influence, implementing agricultural projects, modern irrigation systems, social development projects and the fulfillment of pending commitments with the surrounding communities.

In addition, in 2013 Yanacocha made US$6.1 million in contributions for social investment through the Cajamarca Mining Solidarity Fund. Also, Yanacocha has invested US$1 million on maintenance of the Kuntur Wasi road.

The cumulative social investment made by Yanacocha since 1993 amounts to US$420 million.

During 2014 Yanacocha will be focused on further improving its relationship with local communities and maximizing the value and recognition of its social investment in order to ensure the viability and legitimacy of its activities.

Security

Yanacocha has 34 security employees on its payroll, including 6 employees responsible for the security of the region as a whole. In addition, Yanacocha has a contracted security force of over 201 persons assigned to rotating shifts at its mine, its Lima offices, the city of Cajamarca, checkpoints along the road to the coast of Peru and residential areas in Cajamarca. The Conga project has a total of 80 security personnel responsible for patrolling and providing security to the project, as well as a contracted security force of over 106 persons assigned to rotating shifts at the project.

As of March 31, 2014, none of Yanacocha’s employees, the properties on which it conducts mining operations or its Lima headquarters had been the target of a terrorist incident.

43

Mining and Processing Concessions

Yanacocha’s mining activities encompass 271,647 hectares covered by 394 mining concessions. Of the 271,647 hectares, another entity, SMRL Chaupiloma Dos de Cajamarca, holds the mining rights related to 105,634 hectares, covered by 144 mining concessions. Minera Yanacocha S.R.L. holds the mining rights related to 166,013 hectares covered by 250 mining concessions. Chaupiloma has assigned these mining concessions to Yanacocha pursuant to several assignments of mining rights, each with an initial term of 20 years, which are renewable at Yanacocha’s request for an additional 20-year term. Yanacocha owns four processing concesions, including a processing concession for the Conga project.

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 thereof, 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 24,702 hectares of the surface land covering its Carachugo, Chaquicocha, Maqui Maqui, Haussing, Laboratorio, Línea de Alta Tensión, Presas, Museo, 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.

In addition, as of December 31, 2013, Yanacocha had acquired 24,702 hectares, including 5,802 hectares of surface rights with respect to the Conga deposit, 3,589 hectares for Carachugo/San José/Chaquicocha, 2,154 hectares for Yanacocha and 1,652 hectares for Quilish. 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 (DIGAM), the National and the Local Water Authorities (ANA and ALA/AAA, respectively), and the Ministry of Health (DIGESA). 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. Currently two additional modifications are in process for both the SYE and SYO, with approval expected in second and third quarter of 2014, respectively. After an EIS and the Benefit Concession and Mining Permits are approved and construction activities are initiated, a governmental-accredited environmental auditing agency (OEFA in the Spanish acronym) is required to audit those operations. All of the mining operations and the China Linda lime plant have been and continue to be audited as required with no significant environmental issues identified.

44

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. Although procedures for permit applications and approvals have been historically faster in Peru than in the United States, current procedures and the existing regulatory environment are more complex, time-consuming and susceptible to potential delays.

Yanacocha has informed us that as a result of the enactment of the new Water Resources Law and the new Rule for Exploration Activities, new environmental quality standards for water and new maximum permissible limits will require the adoption of new technologies for the adjustment of water treatment and management systems. In 2010, Yanacocha implemented a Water Management Project to improve its treatment system and water management in order to comply with the new water regulations.

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, 2013, Yanacocha experienced 56 injuries compared to 119 during the year ended December 31, 2012.

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 percent of the voting shares, none of the following may occur: (i) an increase or decrease in Yanacocha’s capital, (ii) the issuance of any debentures, (iii) any sale of an asset whose book value is at least 50 percent of the paid-in capital relating to such asset, (iv) any amendment to the Yanacocha By-Laws in order to change its business form, (v) the merger, consolidation, dissolution or liquidation of Yanacocha or (vi) 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 prior to 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 percent 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 percent 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 (i) a disposal or sale of more than 20 percent by value of Yanacocha’s fixed assets, (ii) any planned shutdown or cessation of Yanacocha’s mining activities that is planned to last for more than one year, (iii) any capital expenditure by Yanacocha exceeding US$20 million, (iv) any disposal or sale by Yanacocha of the mining rights covered by certain concessions or (v) the approval of the construction of a project in the area owned by Yanacocha (other than the Carachugo mine and processing facilities).

45

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 in order 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. In the event that not all of the partners wish to exercise this right or some indicate their decision to acquire a smaller share than that to which they are entitled, the other partners will be entitled to 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.

46

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 2013, Yanacocha accrued fees of US$52.9 million owed to Newmont Peru and its affiliates under the Management Contract.

D.Property, Plants and Equipment

Our Properties

Introduction

We currently have five wholly-owned operating mines (Julcani, Uchucchacua, Orcopampa, Mallay and Breapampa) along with four wholly-owned former operating mines at which we are currently conducting exploration activities (Poracota, Recuperada, Antapite and Shila-Paula). We have controlling interests in two mining companies which operate the Colquijirca, Marcapunta and La Zanja mines. We also own an electric power transmission company, an energy generation company, a chemical processing company, an engineering services consulting company and an insurance brokerage company. We also have non-controlling interests in Yanacocha, Cerro Verde and Tantahuatay mines. See “—Buenaventura—C. Organizational Structure” and “Intermediate Holding Companies, Subsidiaries and Equity Participations.” Set forth below is a map of our principal mining operations.

48

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 percent of production value, subject to certain conditions. Operations started in the Orcopampa mine in 1965. In 2013, we made lease payments of US$23.8 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 of 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 conditioned 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.

In 2013, we focused geological exploration in the 3,540 level on the veins Nazareno, Esperanza, Prosperidad, Lucia, Concepción and on the Melissa ore body, which lies below the 3,540 level on veins Nazareno Este, Esperanza and Lucía.

As of December 31, 2013, proven and probable ore reserves were 634,206 tons, with 43.20 grams per ton of silver and 16.39 grams per ton of gold. We have estimated NRM of 232,687 tons, with 96.34 grams per ton silver and 15.98 grams per ton gold.

Set forth below are certain unaudited operating data for the periods shown for Orcopampa, calculated on the basis of 100 percent of the mine’s production.

Poracota

Poracota is an underground mine that is wholly-owned and operated by us. Poracota is located in the province of Condesuyos, department of Arequipa, at an altitude of between 4,500 and 5,000 meters above sea level. Operations at our Poracota mine commenced in February 2007.

Gold mineralization at Poracota has been classified as an epithermal high sulfidation system, which is formed by two main areas, Huamanihuayta and Perseverancia. The more important veins are María Fé, Silvana, Rocio and Malena, which are hosted by the tertiary rocks of the Huamanihuayta volcano.

During 2013, we conducted underground exploration tunnels and diamond drilling, mainly focused on the structures Amparo, Olenka, Patricia, María Eugenia and Manto Aguila. In 2014, we will continue our exploration efforts in those structures.

As of December 31, 2013, we calculated Poracota’s proven and probable ore reserves of 107,600 tons, with 10.66 grams per ton of gold and 0.75 grams per ton of silver. The NRM for sulfides and oxides was 36,240 tons, with 11.45 grams per ton of gold and 3,713,954 tons, with 1.10 grams per ton of gold and 4.71 grams per ton of silver, respectively.

Uchucchacua

The Uchucchacua mine is wholly-owned and operated by us. Operations started 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 mineralization.

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 2,700 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.

50

In the fourth quarter of 2013 we completed construction of a manganese sulfate plant (Rio Seco), located 102 kilometers north of Lima, which will treat concentrates from the Uchucchacua mine and will improve silver recovery in addition to producing manganese sulfate monohydrate, which is mainly used in agriculture. We expect to begin operating Rio Seco in the second quarter of 2014, after pre-commissioning and commissioning tests.

In 2013, we explored three mines: Socorro, Carmen and Huantajalla. In 2014, we plan to create exploration tunnels and conduct diamond drilling in the same areas.

At December 31, 2013, proven and probable ore reserves were 3,836,557 tons, with 526.04 grams per ton of silver, 1.04 percent lead and 1.40 percent zinc. Total NRM was 2,798,410 tons, with 516.46 grams per ton of silver, 1.44 percent lead and 1.78 percent zinc.

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 percent interest in La Zanja and Newmont holds a 46.94 percent 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 and carbon-in-column circuits are utilized 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 March 2014. We have installed a new Merrill Crowe plant to retrieve values contained in the silver-rich solution, which will commence operations upon the receipt of pending permits.

During 2013, we performed diamond drillings in areas around San Pedro Sur, Pampa Verde and Alejandra.

Total proven and probable ore reserves at December 31, 2013 were 14,248,314 tons, with 0.73 grams per ton of gold and 6.26 grams per ton of silver. Total NRM of La Zanja was 18,809,166 tons, with 0.72 grams per ton of gold and 6.02 grams per ton of silver.

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.

In 2013, we performed diamond drillings to update model ore distribution and define the gold ore within the colluvial deposit close to the Parccaorcco open pit, where we have recognized disseminated gold that is part of current reserves.

We have installed a new crushing plant, with capacity of 8,000 tons per day, to standardize the sizes of the particles that go to the pad, which will allow for greater leaching and higher gold recovery.

Proven and probable ore reserves as of December 31, 2013 were 2,279,033 tons, with 1.30 grams per ton of gold and 25.61 grams per ton of silver. Total NRM in oxides were 1,535,677 tons, with 0.65 grams per ton of gold and 3.64 grams per ton of silver.

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 principal ore structures: Isguiz, Pierina, María and Fortuna Body.

During 2013, we performed exploration tunnels and diamond drilling, focused on the Isguiz body-vein, the María-Dana system veins and the Jumasha limestone zone. In 2014, we plan to create exploration tunnels and conduct diamond drilling on the same mineralized structures.

As of December 31, 2013, the proven and probable ore reserves were 123,377 tons, with 392.90 grams per ton of silver, 6.64 percent lead and 8.47 percent zinc. NRM were 81,085 tons, with 446.06 grams per ton of silver, 5.04 percent lead and 6.33 percent zinc.

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 wholly-owned by Coimolache, in which we hold a 40.10 percent equity interest, and operated by us.

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. We have identified several geologic targets with gold mineralization and have conducted detailed studies of the deposits Tantahuatay 2, Ciénaga Norte and Mirador Norte. Currently we are completing the exploration phase at Mirador Sur and Azufre with positive results. In 2014, we have planned to start to define Tantahuatay 3 and Tantahuatay 4.

Tantahuatay 2 consists of hydrothermal breccia bodies, formed by silicified tuff fragments in a matrix of quartz-alunite-pyrophyllite, with iron oxides inside fractures and cavities, which contain free gold and electrum as submicroscopic particles.

Ciénaga Norte and Mirador Norte consist of hydrothermal breccia bodies, formed in facies of vuggy silica and sandy silica, hosted in tuffs and hornblende lavas, which contain free submicroscopic gold mainly in iron oxides.

During 2013, we performed diamond drillings, to update the open pit modeling of Tantahuatay-2 and to explore the ore deposits of Mirador Sur and Azufre.

58

Total proven and probable ore reserves at December 31, 2013 were 51,956,018 tons, with 0.44 grams per ton of gold and 10.80 grams per ton of silver. Total NRM in oxides were 53,736,740 tons, with 0.038 grams per ton of gold and 360 grams per ton of silver. Total NRM in sulfides were 149,727,390 tons, with 0.27 grams per ton of gold, 446 grams per ton of silver and 0.72 percent copper.

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 percent at December 31, 2013.

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 percent zinc, while its lead concentrate typically contains 51 percent lead. The concentrates are sold to local smelters and traders depending on market conditions. Mining at Marcapunta Norte is conducted through the room and pillars method, from which copper concentrates are produced. El Brocal’s copper concentrates typically contains 25 percent copper, 4 percent silver and 8 percent arsenic. The concentrates are sold to local traders.

The Huaraucaca concentrator plant processes ore from both mines. In 2013, average treated ore at the plant reached up to 9,270 tons per day. 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 continued throughout 2013. El Brocal obtained approval for its EIS relating to a diamond drilling program at the Marcapunta deposit.

In 2013, we invested US$184.0 million to expand the project and have invested a total of US$462.0 million since 2008. We also continued exploration in prospective areas such as San Gregorio, Marcapunta Oeste and other areas, at a cost of US$5.2 million. Construction and implementation of the crushing, milling and flotation processes under our expansion program, as well as construction of the Huachuacaca tailings facility, are expected to be finished during the first quarter of 2014.

59

In 2014, we plan to conduct an initial exploration program in Huancavelica at the Yanamina Millocucho zone to continue prospecting activities that we commenced in 2013. The expansion project, which will enable us to increase treatment capacity to up to 18,000 tons of ore per day, should be completed during the first quarter of 2014.

Total proven and probable reserves of Colquijirca as of December 31, 2013 were 45,926,000 tons, with 28.62 grams of silver per ton, 2.53 percent of zinc and 0.86 percent of lead. Total proven and probable reserves of Marcapunta Norte as of December 31, 2013 were 23,052,000 tons with 18.66 grams of silver per ton, 0.40 grams of gold per ton and 2.26 percent copper. Total NRM as of December 31, 2013 for Colquijirca was 27,747,192 tons, with 14.00 ounces per ton of silver, 1.60 percent zinc and 0.46 percent lead. Total NRM for Marcapunta Norte was 34,226,815 tons, with 20.53 grams per ton of silver, 0.43 grams per ton of gold and 1.58 percent copper.

Reserves

We calculate our ore reserves by methods generally applied within the mining industry and in accordance with Commission Industry Guide 7. All mineral reserves are estimated quantities of proven and probable ore 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, 2013, 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 9.27 million ounces of gold representing a 1% decrease over our total proven and probable reserves as of December 31, 2012, which were estimated to be 9.35 million ounces of gold.

As of December 31, 2013, our total proven and probable reserves, including our equity share in El Brocal (54.07%), La Zanja (53.06%), Coimolache (40.10%) and Yanacocha (43.65%), were estimated to be 167.25 million ounces of silver, representing a 15% increase over our total proven and probable reserves as of December 31, 2012, which were estimated to be 145.38 million ounces of silver.

The following table lists the proven and probable ore reserves, as of December 31, 2013, for each of our consolidated mining operations and the Tantahuatay mine, in which we have a 40.10 percent equity interest, calculated on the basis of 100 percent of each mine’s reserves and US$1,200 per ounce of gold and US$20.00 per ounce of silver.

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 1 kilometer southeast of the mined out Carachugo deposit and 300 meters south of the Chaquicocha Norte pit. Mining at this deposit is expected to be completed by 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 is 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 will finish in February 2014.

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 expects to reopen in 2017.

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.

64

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.

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 2010 and will be finished by 2016. La Quinua Sur is scheduled to commence mining activities in May 2014 and finish in 2019. The ore mined from this pit will be processed at the La Quinua leach pad.

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 will complete operations in April 2014.

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 finished 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, 2013 for Yanacocha and the Conga project. Calculations with respect to the estimates of proven and probable reserves are based on a gold price of US$1,300 per ounce and a copper price of US$3.00 per pound as of December 31, 2013. 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 and the Conga project’s proven and probable reserves are calculated prior to any losses during metallurgical treatment.

As of December 31, 2013, the Yanacocha district’s proven and probable reserves (excluding the Conga project’s proven and probable reserves) were estimated to be 5.7 million ounces of gold, a 3 percent decrease from the Yanacocha district’s proven and probable reserves as of December 31, 2012, which were estimated to be 5.9 million ounces of gold. The decrease in reserves of gold was mainly due to mine depletion, and to a lesser extent, metal price decreases, reserve revisions and leach and stockpile inventory changes.

As of December 31, 2013, proven and probable reserves were calculated using a gold price assumption of $1,300 per ounce.

As of December 31, 2013, the Conga project’s proven and probable reserves were estimated to be 12.6 million ounces of gold and 3.3 billion pounds of copper, unchanged from reserves reported in 2012.

As of December 31, 2013, Yanacocha’s total proven and probable reserves (including the Conga project) were estimated to be 18.3 million ounces of gold, representing a 1 percent decrease over Yanacocha’s total proven and probable reserves as of December 31, 2012; which were estimated to be 18.5 million ounces of gold. Yanacocha’s total proven and probable reserves of copper were 3.3 billion pounds as of December 31, 2013, the same as reported as of December 31, 2012.

Based on the current recovery rate and estimated gold production levels in 2013, Yanacocha’s proven and probable reserves as of December 31, 2013 will be depleted by 2019 unless Yanacocha continues to add to its reserves. 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, 2012 and 2013 and for the years ended December 31, 2011, 2012 and 2013 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. Our consolidated financial statements for the year ended December 31, 2011 were the first that we prepared in accordance with IFRS. 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: (i) the Julcani, Mallay, Breapampa, Recuperada, Uchucchacua, Orcopampa, Poracota, Antapite, Shila-Paula and Ishihuinca (which was sold in 2013) mining units; (ii) the Colquijirca, Marcapunta, and La Zanja mines, which are owned through consolidated subsidiaries; (iii) Chaupiloma, which receives a royalty payment from Yanacocha; (iv) Condesa, which is mainly a holding company for investments in us, Yanacocha and other affiliated mining companies; (v) Conenhua, which is mainly engaged in the transmission of electric power to Yanacocha and other mining companies; and (vi) other minor subsidiaries. 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. A substantial part of our net income before income tax was derived from our equity interest in Yanacocha. We have a 43.65 percent 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, 2013, we had a 19.58 percent 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 (i) the amount of gold, silver, zinc and copper produced and sold by us; (ii) prevailing world market prices for gold, silver, zinc and copper; (iii) commercial terms with respect to the sale of ore concentrates; and (iv) 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 in order 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.

67

Operating costs and expenses. Operating costs and expenses consist of (i) operating costs, which are direct production costs, the major component of operating expenses; (ii) exploration costs in operational mining sites; (iii) depreciation and amortization expenses; (iv) exploration costs in non-operational mining areas; (v) administrative expenses, which principally consist of personnel expenses; (vi) royalties, which consist of payments to third parties and the Peruvian government to operate leased mining rights; and (vii) 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 of at least 20 percent of its paid-in capital on an unconsolidated basis. An annual contribution of at least 10 percent of net income must be made until such legal reserve equals 20 percent 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 and Ishihuinca mines. Specifically, we pay the applicable lessor a royalty of 10 percent of the value of the concentrates produced in the Orcopampa mine and 7 percent of the value of the concentrates produced in the Ishihuinca mine. 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.

68

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

| · | accrual for mine closing costs;

| · | inventories;

| · | deferred income tax asset and recoverability; and

| · | fair value of the liability related to share-based payment transactions;

Other significant accounting policies include:

| · | contingencies;

| · | deferred stripping costs; 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, 2011 and 2012 were reviewed by an independent consultant, Algon Investment S.R.L. Algon Investment S.R.L. is in the process of reviewing the framework used to estimate proven and probable reserves for our wholly-owned mines as of December 31, 2013. The conceptual framework used to estimate proven and probable reserves for El Brocal’s mines as of December 31, 2011 and 2012 were reviewed by independent consultants, AMEC plc and MINTEC Inc., respectively. MINTEC Inc. 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, 2013.

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.

69

Mine development costs

We review and evaluate our accounting policy regarding mine development costs, which requires judgment in determining whether it is likely that future exploitation will result in future economic benefits. The determination of reserves and mineral resources is a complex estimation that entails varying degrees of uncertainty depending on sub-classification, and these estimates directly impact the point of deferral of exploration and mine development costs and the amortization method for development costs. The deferral policy requires us to make certain estimates and assumptions about future events or circumstances—in particular, whether an economically viable extraction operation and mineral sale can be established. Estimates and assumptions made may change as new information becomes available. If, after the expenditure is capitalized, information becomes available suggesting that we are unlikely to recover the expenditure, the amount capitalized is written off in our profit and loss statement for the period in which the new information becomes available.

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 2011, 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” and identified no impairment indication in our long-lived assets.

During the fourth quarter of 2012, 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$3.6 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 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.

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, 2011, 2012 and 2013 impairment evaluation was based on price assumptions reflecting prevailing metals prices for the following years.

70

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, 2013, 2012 and 2011, our valuation allowance totaled US$6.4 million, US$5.3 million, and US$3.8 million, respectively.

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.

71

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.

Accrual for mine closure costs

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 the obligation and related asset.

Following our accounting treatment, we have recorded an accrual for mine closure costs of US$145.2 million, as of December 31, 2013 in order to comply with governmental requirements for environmental remediation.

We assess our provision for closure of mining units annually. It is necessary to make significant estimates and assumptions in determining this provision 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.

Fair value of derivative financial instruments

Outstanding derivative contracts. We recognize derivative instruments as assets or liabilities, measured at their fair value, in our consolidated statements of financial position, pursuant to IAS 39, “Financial Instruments — Recognition and Measurement”.

Subsidiary derivative contracts. During 2011 and 2013, our indirect subsidiary, El Brocal, entered into price-hedging option contracts at zero cost to protect future cash flows derived from sales in 2011, 2012 and 2013, respectively. Derivative contracts are recognized as assets and liabilities at fair value in the consolidated financial statements. El Brocal applies hedge accounting for those transactions that meet the specific criteria applicable in accordance with IAS 39. As of December 31, 2011, 2012 and 2013, El Brocal recognized an asset of US$1.3 million, null in 2012, and a liability of US$1.1 million, respectively. As of December 31, 2012, El Brocal was not a party to any hedging transactions and had no outstanding hedging commitments.

72

Our derivative contracts. As of December 31, 2011, 2012 and 2013, neither we nor any of our wholly-owned subsidiaries held gold derivative contracts.

Fair value of the liability related to long-term officer compensation

Our senior executive officers are granted share appreciation rights, which can only be settled in cash, if the executive is working for us at each program’s settlement date. These programs are mainly structured in a ten-year term, allocated in several programs with progressive maturities. The average price of the granted share appreciation rights is assigned based on last quarter market quotation of the shares before the grant date and the settlement price is determined based on the variation of the market prices at the maturity date as compared to the price at the date of the grant.

We used the Turnbull & Wakeman Method to estimate the fair value of this liability and the principal assumptions made are as follows: the historical volatility, risk-free interest rate, dividend yield, period covered by the program and market value of the shares at closing. See Note 13(d) 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 25 to the Financial Statements.

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

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.

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.

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.

Depreciation and amortization of assets whose useful life is longer than the life of the mine is calculated on a unit-of-production basis over the economically recoverable reserves of the mine. Depreciation and amortization of assets whose useful life is shorter than the life of the mine is calculated using the straight-line method.

73

The units of production are measured in recoverable tons of concentrate. The unit-of-production rate for depreciation and amortization takes into account expenditures incurred to date.

Expected recovery rates used to estimate mineral contained in in-process inventories

For determining the quantity of mineral contained in the products in process we use a reasonable methodology to estimate the mineral content that is treated at the date of the consolidated financial statements. The amount of mineral added in the products in process is determined by the sampling of mill volumes and the daily production records. The sampling and assays determine the head grade of the mineral added to the products in process.

The recovery rates for leach platforms in process are determined by metallurgical sampling. The mineral recoverability of the leach platforms, once the production process begins, can be reasonably estimated. The rate is determined using pilot laboratory tests, historic trends and other factors. Processes and recovery rates are monitored continuously, and recovery rates are adjusted periodically as additional information becomes available and as related technology changes.

Deferred stripping cost

Stripping costs incurred in the development of a mine before production commences (development-phase stripping) are capitalized as part of the cost of constructing the mine and subsequently amortized over the life of the mine on a unit-of-production basis. Capitalization of development-phase stripping ceases when production of the mine commences.

Where a mine operates several open pits that are regarded as separate operations for the purpose of mine planning, stripping costs are accounted for separately by reference to the ore from each separate pit. If, however, the pits are highly integrated for the purpose of the mine planning, the second and subsequent pits are regarded as extensions of the first pit in accounting for stripping costs. In such cases, the initial stripping (i.e., overburden and other waste removal) of the second and subsequent pits is considered to be production-phase stripping relating to the combined operation.

Production-phase stripping can be directly related to inventory production or to grant better access to ore that will be extracted in the future. Stripping costs related to inventory production are recorded as part of production cost of such inventory. Stripping costs related to granting better access to ore that will be extracted in the future are recognized as non-current assets, included in “Mining rights, development cost and property, plant and equipment, net” caption in the consolidated statement of financial position, and subsequently depreciated on a unit-of-production basis over the life of the component in the ore deposit which is more accessible due to stripping activity. The cost is presented net of accumulated depreciation and impairment losses if events or changes of circumstances indicate that the carrying value may not be recoverable.

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

74

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.

The asset’s residual value, useful lives and methods of depreciation are reviewed, and adjusted if appropriate, at each financial year-end.

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 18(a) and 28(b) to the Financial Statements.

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 Buenaventura Ingenieros S.A. 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.

Results of Operations for the Years Ended December 31, 2013 and 2012

Net sales. Net sales decreased by 17 percent, from US$1,496.3 million in 2012 to US$1,241.3 million in 2013, mainly due to a decrease in the average realized prices of gold, lead, silver, zinc and copper, and decreases in the volume of silver and zinc sold, partially offset by a higher volume of gold, lead and copper sold. The following tables reflect the average realized prices and volumes sold of gold, silver, lead, zinc and copper during the years ended December 31, 2012 and 2013:

Average Realized Price |  | Year ended December 31, |
|  | 2012 |  |  | 2013 |  |  | Variation |

75

(a) Gold sales. Average realized sales price for gold decreased from US$1,677.96 per ounce in 2012 to US$1,392.18 per ounce in 2013. Gold sales volume increased from 439,630 ounces in 2012 to 458,499 ounces in 2013, mainly due to increased gold production at our Breapampa and La Zanja mining units. The combined effect of these changes resulted in a US$101.4 million decrease in income from sales of gold in 2013 compared to 2012.

(b) Silver sales. Average realized sales price for silver decreased from US$31.07 per ounce in 2012 to US$22.33 per ounce in 2013. Silver sales volume decreased from 17,483,490 ounces in 2012 to 16,329,314 ounces in 2013, mainly due to decreased silver production at our Colquijirca mine. The combined effect of these changes resulted in a US$182.1 million decrease in income from sales of silver in 2013 compared to 2012.

(c) Lead sales. Average realized sales price for lead increased from US$2,075.82 per ton in 2012 to US$2,104.63 per metric ton in 2013. Lead sales volume increased from 25,587 tons in 2012 to 26,584 tons in 2013, mainly due to increased lead production at our Julcani and Mallay mining units. The combined effect of these changes resulted in a US$3.1 million increase in income from sales of lead in 2013 compared to 2012.

(d) Zinc sales. Average realized sales price for zinc decreased from US$1,918.98 per ton in 2012 to US$1,869.22 per ton in 2013. Zinc sales volume decreased from 43,149 tons in 2012 to 38,084 tons in 2013, mainly due to decreased zinc production at our Colquijirca mine. The combined effect of these changes resulted in a US$11.7 million decrease in income from sales of zinc in 2013 compared to 2012.

(e) Copper sales. Average realized sales price for copper decreased from US$7,938.49 per metric ton in 2012 to US$7,179.50 per metric ton in 2013. Copper sales volume increased from 22,348 tons in 2012 to 25,406 tons in 2013, mainly due to increased copper production at our Colquijirca mining unit. The combined effect of these changes resulted in a US$4.8 million increase in income from sales of copper in 2013 compared to 2012.

The revenues from gold, silver, lead, zinc and copper mentioned above do not include refinery charges and penalties incurred, which amounted to US$142.0 million in 2013 compared to US$147.9 million in 2012. See Note 18 to the Financial Statements.

Royalty income. In 2013, royalty income received by our subsidiary, Chaupiloma, amounted to US$44.2 million, representing a 34 percent decrease from the US$67.2 million of royalty income received in 2012. This decrease is attributed to decreased sales by Yanacocha in 2013, which resulted mainly from a decrease in the average realized price of gold and a decrease in Yanacocha’s production. Yanacocha pays Chaupiloma, in which we directly and indirectly hold a 60 percent interest, a royalty equal to 3 percent of Yanacocha’s net sales.

Total operating costs. Total operating costs increased by 8 percent, from US$938.9 million in 2012 to US$1,016.8 million in 2013, due to the following:

(a) Cost of sales, excluding depreciation and amortization, increased by 4 percent, from US$625.2 million in 2012 to US$653.5 million in 2013, mainly due to a US$42.4 million increase in services provided by third parties, a US$14.4 million increase in operating leases and a US$11.1 million increase in personnel costs, partially offset by a US$15.9 million decrease in spare parts and supplies consumption, a US$14.0 million decrease in cost of concentrate purchased from third parties and a US$10.2 million decrease in other production costs.

The increases in services provided by third parties, operating leases and personnel costs were mainly due to: (i) the impact of new production costs incurred in connection with operations at our Mallay and Breapampa mining units, which commenced in April and November 2012, respectively, (ii) an increase in exploration activities and diamond drilling works during 2013 as compared to 2012, in order to maintain our ore reserves level, and (iii) an increase in the volume of mineral treated in 2013 compared to 2012, especially in the Marcapunta Norte and Tajo Norte mining units.

76

(b) Exploration in units in operation increased by 9 percent, from US$153.0 million in 2012 to US$167.1 million in 2013. These increased costs were mainly due to an increase in exploration projects at our Orcopampa, Poracota, and Uchucchacua mines. See Note 20 to the Financial Statements.

(c) Depreciation and amortization costs increased by 35 percent, from US$123.0 million in 2012 to US$165.5 million in 2013, mainly due to: (i) higher depreciation and amortization costs incurred in our Breapampa and Mallay mining units from US$12.4 million in 2012 to US$25.5 million in 2013, as a result of our beginning operations at these mining units in November and April 2012, respectively, and (ii) a US$9.2 million increase in depreciation costs incurred in our Colquijirca mining unit as a result of tailing areas put into operation during 2012.

(d) Royalty expenses to third parties and the Peruvian government decreased by 19 percent, from US$37.7 million in 2012 to US$30.6 million in 2013. Royalties paid to third parties amounted to US$35.2 million and US$23.9 million in 2012 and 2013, respectively. Royalties paid to the Peruvian government amounted to US$2.5 million and US$6.7 million in 2012 and 2013, respectively. The decrease in royalties paid to third parties and Peruvian government was mainly due to the decreased gold production at our Orcopampa mining unit by 14 percent, from 260,379 ounces produced in 2012 to 224,671 ounces produced in 2013, and the decrease in the price of gold in 2013 compared to 2012.

Total operating expenses. Operating expenses decreased by 33 percent, from US$202.1 million in 2012 to US$136.4 million in 2013, due to changes in the following components:

(a) Administrative expenses decreased by 22 percent, from US$99.3 million in 2012 to US$77.5 million in 2013, mainly due to a reversal of expenses by US$20.2 million recorded for long-term officers’ compensation (stock appreciation rights). See Note 22 to the Financial Statements.

(b) Exploration in non-operational areas decreased by 66 percent, from US$95.5 million in 2012 to US$32.8 million in 2013, due to decreased expenditures in exploration areas, mainly in the Tambomayo, Trapiche, San Gregorio, Breapampa, Focus and Consolidada de Hualgayoc projects. See Note 23 to the Financial Statements.

(c) Impairment losses of long-lived assets increased by 82 percent, from US$3.6 million in 2012 to US$6.6 million in 2013, due to the impairment evaluation carried out on our long-lived assets as of December 31, 2013, which resulted in an additional reduction in the carrying amount of mining concessions, development costs and property, plant and equipment to their recoverable amounts. See Note 11 to the Financial Statements.

Operating income. As a result of the foregoing, operating income decreased by 69 percent, from US$422.5 million in 2012 to US$132.3 million in 2013.

Share in the results of related parties under equity method. Income from equity investments in related parties decreased by 123 percent, from an income of US$481.8 million in 2012 to a loss of US$108.5 million in 2013, mainly due to decreases in income from our equity investments in Yanacocha, Cerro Verde and Coimolache. Income from our interest in Yanacocha decreased by 186 percent, from an income of US$285.6 million in 2012 to a loss of US$245.4 million in 2013. Income from our interest in Cerro Verde decreased by 26 percent, from US$156.0 million in 2012 to US$116.2 million in 2013. Income from our interest in Coimolache decreased by 48 percent, from US$40.2 million in 2012 to US$20.8 million in 2013, mainly due to the impact of a decrease in the prices of gold and silver and decreased silver production at Tantahuatay mine.

Income tax. Provision for income tax decreased by 40 percent, from US$144.2 million in 2012 to US$86.6 million in 2013, mainly due to a US$894.8 million decrease in pre-tax income, from US$907.3 million in 2012 to US$12.5 million in 2013.

Non-controlling interest. Non-controlling interest expense decreased by 54 percent, from US$59.4 million in 2012 to US$27.5 million in 2013, mainly due to a decrease in contribution of profits from El Brocal, Chaupiloma and La Zanja. See Note 16 to the Financial Statements.

77

Net profit (loss). As a result of the foregoing, net profit decreased by 114 percent, from a net profit of US$703.6 million in 2012 to a net loss of US$101.7 million in 2013. As a percentage of net sales, net loss was 8 percent in 2013 and net profit was 47 percent in 2012.

Results of Operations for the Years Ended December 31, 2012 and 2011

Net sales. Net sales increased by 0.2 percent, from US$1,493.9 million in 2011 to US$1,496.3 million in 2012, mainly due to an increase in the average realized prices of gold and increases in the volume of silver, lead and zinc sold, partially offset by lower volumes of gold and copper sold. The following tables reflect the average realized price and volume sold of gold, silver, lead, zinc and copper during the years ended December 31, 2011 and 2012:

(a) Gold sales. The average sales price for gold increased from US$1,574.45 per ounce in 2011 to US$1,677.96 per ounce in 2012. Gold sales volume decreased from 505,894 ounces in 2011 to 439,630 ounces in 2012, primarily due to decreased gold production at our Poracota and Antapite mining units. These combined effect of these changes resulted in a US$52.9 million decrease in income from sales of gold in 2012 compared to 2011.

(b) Silver sales. Average realized silver prices decreased from US$35.36 per ounce in 2011 to US$31.07 per ounce in 2012. The volume of silver sales increased from 14,843,193 ounces in 2011 to 17,483,490 ounces in 2012, primarily due to increased silver production at our Uchucchacua and Colquijirca mining units. These combined effect of these changes resulted in a US$18.6 million increase in income from sales of silver in 2012 compared to 2011.

(c) Lead sales. Average realized lead prices decreased from US$2,262.34 per metric ton in 2011 to US$2,075.82 per metric ton in 2012. Additionally, the volume of lead sold increased from 18,192 tons in 2011 to 25,587 tons in 2012, primarily due to increased lead production at our Colquijirca mining unit. The combined effect of these changes resulted in a US$16.0 million increase in income from sales of lead in 2012 compared to 2011.

(d) Zinc sales. Average realized zinc prices decreased from US$2,199.72 per metric ton in 2011 to US$1,918.98 per metric ton in 2012. The volume of zinc sold increased from 33,307 tons in 2011 to 43,149 tons in 2012, primarily due to increased zinc production at our Uchucchacua and Mallay mining units. The combined effect of these changes resulted in a US$10.8 million increase in income from sales of zinc in 2012 compared to 2011.

(e) Copper sales. Average copper prices decreased from US$8,567.64 per metric ton in 2011 to US$7,938.49 per metric ton in 2012. The volume of copper sold decreased from 23,231 tons in 2011 to 22,348 tons in 2012, largely due to decreased copper production at our Colquijirca mine. These changes resulted in a US$15.6 million decrease in income from sales of copper in 2012 compared to 2011.

The revenues from gold, silver, lead, zinc and copper mentioned above do not include refinery charges and penalties incurred, which amounted to US$147.9 million in 2012, compared to US$128.0 million in 2011. See Note 18 to the Financial Statements.

Royalty income. In 2012, royalty income received by our subsidiary, Chaupiloma, amounted to US$67.2 million, representing a 7 percent increase from the US$62.7 million of royalty income received in 2011. This increase is attributed to increased sales by Yanacocha in 2012, which resulted primarily from an increase in the average realized price of gold and an increase in Yanacocha’s production. Yanacocha pays Chaupiloma, in which we directly and indirectly hold a 60 percent interest, a royalty equal to 3 percent of Yanacocha’s net sales.

Total operating costs. Total operating costs increased by 32 percent, from US$712.2 million in 2011 to US$938.9 million in 2012, due to the following:

(a) Cost of sales, excluding depreciation and amortization, increased by 40 percent, from US$446.2 million in 2011 to US$625.2 million in 2012, mainly due to a US$100.9 million increase in services provided by third parties and a US$32.3 million increase in spare parts and supplies consumption. The increase was mainly due to: (i) a US$75.6 million increase in the cost of the inventories held at the beginning of 2012 as compared to the beginning of 2011, (ii) a US$44.3 million increase reflecting the impact of costs incurred in connection with commencing operations at our Mallay and Breapampa mining units; and (iii) a US$36.6 million increase reflecting an increase in the services and raw materials provided by contractor suppliers at our Orcopampa and Uchucchacua mining units due to an increase in exploration activities and diamond drilling works in order to maintain our ore reserves level and an increase in cost related to the higher volume of mineral treated in 2012.

(b) Exploration in units in operation increased by 40 percent, from US$109.4 million in 2011 to US$153.0 million in 2012. These increased costs were principally due to an increase in exploration projects at our Orcopampa, Poracota, Uchucchacua, Mallay and Antapite mines. See Note 20 to the Financial Statements.

(c) Depreciation and amortization costs increased by 28 percent, from US$96.4 million in 2011 to US$123.0 million in 2012, mainly due to: (i) a US$13.4 million increase in the depreciation and amortization of the tailing areas put into operation at our Colquijirca mining unit during 2012 and (ii) a US$9.9 million increase in acquired assets put into operation during 2012 at our La Zanja mining unit.

(d) Royalty expenses to third parties and Peruvian government decreased by 37 percent, from US$60.3 million in 2011 to US$37.7 million in 2012. Royalties paid to third parties amounted to US$32.0 million and US$35.2 million in 2011 and 2012, respectively. Royalties paid to Peruvian government amounted to US$28.2 million and US$2.5 million in 2011 and 2012, respectively. The decrease in royalties paid to third parties and Peruvian government was mainly due to Peruvian legislative changes. Peruvian legislation requires owners of mining concessions to pay the Peruvian government for exploitation of metallic and non-metallic resources. Prior to October 1, 2011, mining royalties were calculated with rates ranging from 1 to 3 percent of the value of mineral concentrates or equivalent, according to quoted market price published by Ministry of Energy and Mines. Beginning on October 1, 2011, Peruvian government instituted a new mining royalty and tax regime. See “Item 4. Information on the Company—Buenaventura—B. Business Overview—Regulatory Framework—Mining Royalties and Taxes” for additional information regarding mining royalties and taxes now applicable to us.

Total operating expenses. Operating expenses increased by 44 percent, from US$140.1 million in 2011 to US$202.1 million in 2012, due to changes in the following components:

(a) Administrative expenses increased by 32 percent, from US$75.2 million in 2011 to US$99.3 million in 2012, mainly due to (i) a US$7.7 million increase in expenses recorded for long-term officers’ compensation (stock appreciation rights) and (ii) a US$5.7 million increase in other management expenses related to foreign engineering consulting services. See Note 22 to the Financial Statements.

(b) Exploration in non-operational areas increased by 92 percent, from US$49.6 million in 2011 to US$95.5 million in 2012, due to higher expenditures in exploration areas, primarily Shila, Trapiche, San Gregorio and Chancas. See Note 23 to the Financial Statements.

(c) Impairment of long-lived assets resulted in a loss of US$3.6 million being recorded in 2012. We evaluated our long-lived assets for impairment as of December 31, 2012, which resulted in a reduction in the carrying amount of mining concessions, development costs and property, plant and equipment to their recoverable amount. See Note 11 to the Financial Statements.

79

Operating income. As a result of the foregoing, operating income decreased by 40 percent, from US$704.4 million in 2011 to US$422.5 million in 2012.

Share in the results of related parties under equity method. Income from equity investments in related parties decreased by 3 percent, from US$496.8 million in 2011 to US$481.8 million in 2012, mainly due to decreases in income from our equity investments in Yanacocha and Cerro Verde, partially offset by the effect of an increase in income from our equity investment in Coimolache. Income from our interest in Yanacocha decreased by 7 percent, from US$308.1 million in 2011 to US$285.6 million in 2012. Income from our interest in Cerro Verde decreased by 25 percent, from US$208.7 million in 2011 to US$156.0 million in 2012. Income from our interest in Coimolache increased from US$9.6 million in 2011 to US$40.2 million in 2012, due to the impact of increased gold production at Tantahuatay mine.

Income tax. Provision for income tax decreased from US$211.6 million in 2011 to US$144.2 million in 2012, mainly due to a US$293.2 million decrease in pre-tax income, from US$1,200.5 million in 2011 to US$907.3 million in 2012.

Non-controlling interest. Non-controlling interest expense decreased by 42 percent, from US$101.6 million in 2011 to US$59.4 million in 2012, mainly due to a decrease in contribution of profits from El Brocal and La Zanja, partially offset by an increase in contribution of profits from Chaupiloma. See Note 16 to the Financial Statements.

Net profit. As a result of the foregoing, net profit decreased by 21 percent, from US$887.3 million in 2011 to US$703.6 million in 2012. As a percentage of net sales, net profit was 47 percent in 2012 as compared to 59 percent in 2011.

B. Liquidity and Capital Resources

As of December 31, 2013, we had cash and cash equivalents of US$61.9 million, as compared to US$186.7 million as of December 31, 2012.

Cash provided by operating activities for the years ended December 31, 2013 and 2012. Net cash and cash equivalents provided by operating activities were US$419.3 million in 2013 compared to US$361.2 million in 2012. The increase in net cash flow provided by operating activities was mainly attributable to: (i) an increase in value-added tax recovered, from US$40.9 million in 2012 to US$66.9 million in 2013; (ii) decreased payments to third parties, from US$812.7 million in 2012 to US$742.2 million in 2013; (iii) decreased income tax paid, from US$136.3 million in 2012 to US$66.4 million in 2013; and (iv) decreased royalty payments, from US$39.0 million in 2012 to US$30.6 million in 2013, mainly as a result of decreased royalty payments to third parties; partially offset by: (i) increased payments to workers, from US$201.5 million in 2012 to US$216.8 million in 2013; (ii) increased interest payments, from US$1.5 million in 2012 to US$11.5 million in 2013 (iii) decreased proceeds from sales, from US$1,410.1 million in 2012 to US$1,351.4 million in 2013; (iv) decreased royalties received from Yanacocha, from US$76.1 million in 2012 to US$50.6 million in 2013; and (v) decreased dividends received from Coimolache, from US$16.5 million in 2012 to US$9.8 million in 2013.

Cash provided by operating activities for the years ended December 31, 2012 and 2011. Net cash and cash equivalents provided by operating activities were US$361.2 million in 2012 compared to US$567.5 million in 2011. The decrease in net cash flow provided by operating activities was mainly attributable to: (i) decreased proceeds from sales, from US$1,505.5 million in 2011 to US$1,410.1 million in 2012; (ii) increased payments to third parties, from US$672.5 million in 2011 to US$812.7 million in 2012; and (iii) increased income tax paid, from US$111.8 million in 2011 to US$136.3 million in 2012; partially offset by: (i) increased royalties received from Yanacocha, from US$56.2 million in 2011 to US$76.1 million in 2012; (ii) increased dividends received from Coimolache, from no dividends received in 2011 to US$16.5 million in 2012; (iii) an increase in value-added tax recovered, from US$22.6 million in 2011 to US$40.9 million in 2012; and (iv) decreased royalty payments, from US$73.8 million in 2011 to US$39.0 million in 2012, mainly as a result of decreased royalty payments to Peruvian government.

Cash used in investing activities for the years ended December 31, 2013 and 2012. Net cash and cash equivalents used in investing activities were US$428.1 million in 2013 compared to US$513.0 million in 2012. The decrease in net cash flow used in investing activities was mainly attributable to: (i) an inflow of US$52.9 million in 2013 as a result of the settlement of financial assets at fair value through profit or loss; and (ii) US$24.5 million received from Coimolache in 2013 as a loan collection; partially offset by an increase in mining concessions, development costs and property, plant and equipment acquisitions, from US$468.4 million in 2012 to US$503.6 million in 2013, in connection with the expansion of the refining plant capacity at our subsidiary, El Brocal; hydroelectric construction at our subsidiary, Huanza; and processing plant construction at our subsidiary, Rio Seco.

Cash used in investing activities for the years ended December 31, 2012 and 2011. Net cash and cash equivalents used in investing activities were US$513.0 million in 2012 compared to US$354.3 million in 2011. The increase in net cash flow used in investing activities was mainly attributable to an increase in mining concessions, development costs and property, plant and equipment acquisitions, from US$317.8 million in 2011 to US$468.4 million in 2012, in connection with hydroelectric construction at our subsidiary, Huanza; and the expansion of the refining plant capacity at our subsidiary, El Brocal.

Cash used in financing activities for the years ended December 31, 2013 and 2012. Net cash and cash equivalents used in financing activities were US$116.1 million compared to US$132.3 million in 2012. The decrease in net cash flow used in financing activities was mainly attributable to: (i) an increase in financial obligations, from US$74.3 million in 2012 to US$237.0 million in 2013; (ii) a decrease in the payment of dividends to shareholders, from US$152.7 million in 2012 to US$78.8 million in 2013; and (iii) a decrease in the payment of dividends to non-controlling shareholders, from US$44.9 million in 2012 to US$13.5 million in 2013; partially offset by an increase in the payment of financial obligations, from US$1.1 million in 2012 to US$260.2 million in 2013.

Cash used in financing activities for the years ended December 31, 2012 and 2011. Net cash and cash equivalents used in financing activities were US$132.3 in 2012 compared to US$325.2 million in 2011. The decrease in net cash flow used in financing activities was mainly attributable to: (i) a decrease in payments for purchase of shares to non-controlling shareholder, from US$225.3 million in 2011 to nil in 2012; (ii) an increase in financial obligations, from US$50.9 million in 2011 to US$74.3 million in 2012; and (iii) a decrease in the payment of dividends to non-controlling shareholders, from US$66.7 million in 2011 to US$44.9 million in 2012; partially offset by: a decrease in proceeds from the sale of investment shares from US$60.4 million in 2011 to nil in 2012; and an increase in the payment of dividends to shareholders, from US$142.5 million in 2011 to US$152.7 million in 2012.

Long-Term Debt

On December 2, 2009, Banco de Crédito del Perú executed a financial lease agreement with Conenhua, Huanza and us in the amount of US$119 million for construction of a hydroelectric power station. The lease was executed in favor of Huanza as lessee, and commits us to act as joint surety of Huanza to guarantee Huanza’s payment obligations. The term of the lease is 10 years and the interest rate is (i) LIBOR plus 4 percent from the first disbursement until six months after the start of commercial operation of the power station and (ii) LIBOR plus 4.1 percent from six months after the start of commercial operation of the power station until maturity. As of each of December 31, 2013 and 2012, the amount outstanding under this lease was US$119 million.

On August 22, 2012, El Brocal entered into a medium-term loan contract with Banco de Crédito del Perú in the amount of US$120 million. This loan was variable rate (three-month LIBOR plus 3 percent) and had a term of four years. The loan was guaranteed by a pledge of one contract for the sale of copper concentrate and one contract for the sale of lead concentrate. The first disbursement of US$60 million was received in November 2012 and the second disbursement of US$60 million was received in May 2013. During the fourth quarter of 2013, this loan was fully repaid using the proceeds provided by the leaseback contract described below and from shareholders’ contributions.

81

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 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 has 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. The quarterly lease payments have an embedded interest rate of LIBOR plus 5.00%. 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.

Exploration Costs and Capital Expenditures

Capital expenditures for 2014 are estimated to be approximately US$270 to US$290 million. These budgeted capital expenditures include the following projects: conclude the El Brocal expansion from 6 kilotons per day to 18 kilotons per day and the construction of the Huanza hydrolectrical plant, start the construction of the Tambomayo project and continue with the development of the Trapiche project.

During 2013, we spent approximately US$32.8 million on “greenfield” and US$167.1 million on “brownfield” exploration-related investments. Our “greenfield” investments were mainly focused on the following exploration projects: Surichata, Paco Paco, Colquemayo, Trapiche, and San Gregorio. Our “brownfield” investments were mainly focused in the Orcopampa, Uchucchacua, Mallay, La Zanja, Tambomayo and Recuperada areas. We financed our 2013 exploration program with internal funds.

In 2014, we intend to invest approximately US$70 to US$80 million in brownfield exploration projects. In 2014, we expect to invest approximately US$35 to US$40 million, mainly in the following greenfield exploration projects: El Brocal, Colquemayo, Pisacalla, Livitaca,and Palla Palla, 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 less 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 are the first that we have prepared in accordance with IFRS. We have 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.

There is only one standard applicable to our Financial Statements issued but not yet effective:

IFRS 9, “Financial Instruments: Classification and Measurement.” This standard does not have a scheduled effective date. IFRS 9 reflects the first phase of IASB work to replace IAS 39 and refers to classification and measurement of financial assets, as defined in IAS 39. Approval of first phase of IFRS 9 will have an effect on classification and measurement of our financial assets, but potentially, it will not have an effect on classification and measurement of our financial liabilities. In subsequent phases, the IASB will address hedge accounting and impairment of financial assets.

C. Research and Development

Not applicable.

D. 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.

E. 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.

As of December 31, 2013, we had no other commercial commitments.

G. 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.

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, 2012 and 2013, 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, 2012 and 2013 by reference to the reconciliations of Cost of sales, excluding depreciation and amortization (by mine and mineral), Selling Expenses (by mine and metal) and Exploration in units in operations (by mine and mineral) expenses to consolidated Cost of sales, excluding depreciation and amortization, consolidated Selling Expenses and consolidated Exploration in units in operations expenses, respectively, set forth below.

YANACOCHA

Introduction

The following discussion should be read in conjunction with the Yanacocha Financial Statements as of December 31, 2012 and 2013 and for the years ended December 31, 2011, 2012 and 2013 and the related Notes thereto included elsewhere in this Annual Report. The Yanacocha Financial Statements are prepared and presented in accordance with U.S. GAAP 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 percent owned by Newmont Mining, through its wholly-owned subsidiary Newmont Second, 43.65 percent by us through our wholly-owned subsidiary Condesa, and 5 percent 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, |
|  | 2013 |  |  | 2012 |  |  | 2011 |
Gold Sales (in thousands of US$) |  |  | 1,457,646 |  |  |  | 2,201,815 |  |  |  | 2,002,602 |

Gold sales. Gold sales decreased by 34 percent, or US$744 million, from 2012 to 2013, 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 24 percent due to lower leach grade material placed on the leach pads compared to the 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.

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 percent of pre-tax profits based on Peruvian labor legislation, (iii) credit from by-product sales, mainly in connection with silver sales, (iv) third party royalites, (v) write downs of ore on leach pads to net realizable value expense and (vi) other costs. Costs applicable to sales increased 2% or US$13.5 million from 2012 to 2013 despite a 23 percent decline in ounces sold. Offsetting the decline in ounces sold were higher mining costs due to the completion of major development projects in late 2012, leach pad write-downs and lower by-product credits, partially offset by lower workers’ participation and labor costs.

92

Other expense (net). Other expense (net) decreased 29 percent or US$32.9 million from 2012 to 2013, primarily due to lower employee serverance program costs incurred in 2013 associated with a program to align Yanaocoha’s organization with future business needs. In addition, lower losses associated with asset sales were incurred in 2013 compared to 2012.

Income tax. Yanacocha’s financial and operating results included income and mining tax expense of US$107.6 million in 2013 compared to US$361.9 million in 2012. The difference was primarily due to Yanacocha’s decreased profitability as the result of lower ounces sold and lower average realized gold prices.

Dividends. During the years ended December 31, 2012 and 2013, 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 Yancocha 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.

93

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.

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 dore 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 prior to 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 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 minimus 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 minimus 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.

94

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.

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.

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 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 in accordance with ASC guidance for reclamation obligations.

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.

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.

96

Recently Issued Accounting Pronouncements

Presentation of an Unrecognized Tax Benefit

In July 2013, 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, 2013 and 2012

Sales

Gold sales. Gold sales decreased by 34 percent, or US$744 million, from 2012 to 2013, 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 24% 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 |  | 2013 |  |  | 2012 |
|  | (ounces) |
Cerro Yanacocha |  |  | 16,393 |  |  |  | 141,038 |
Carachugo |  |  | 437,095 |  |  |  | 698,602 |
Maqui Maqui |  |  | 5,856 |  |  |  | 5,810 |
La Quinua |  |  | 557,915 |  |  |  | 500,524 |
Total |  |  | 1,017,259 |  |  |  | 1,345,992 |

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 percent of pre-tax profits based on Peruvian labor legislation, (iii) credit from by-product sales, mainly in connection with silver sales, (iv) third party royalites, (v) write downs of ore on leach pads to net realizable value expense and (vi) other costs. Costs applicable to sales increased 2% or US$13.5 million from 2012 to 2013 despite a 23 perecent decline in ounces sold. Offseting the decline in ounces sold were higher mining costs due to the completion of major development projects in late 2012, leach pad write-downs and lower by-product credits; partially offset by reductions in workers’ profit participation and labor costs. Costs applicable to sales per ounce of gold increased by 34 percent, from US$517 in 2012 to US$692 in 2013.

Operating costs increased by 15 percent from US$549.9 million in 2012 to US$ 634.7 million in 2013. Operating costs consist primarily of drilling, blasting, loading, hauling and milling costs. These costs increased in 2013 primarily as a result of the completion of major mine development projects in late 2012 under which certain mining costs were capitalized. The volume of commercial tons mined increased from 51.3 million DST in 2012 to 156.5 million DST for the year ended December 31, 2013. This increase was also associated with the completion of the mine development projects in late 2012.

Royalty expense was US$44.2 million in 2013 as compared to US$66.6 million in 2012. The decrease in the royalty expense paid to Chaupiloma, which equals 3 percent of Yanacocha’s net sales, was directly related to the decrease in Yanacocha’s sales revenues.

Workers’ profit participation decreased by 72 percent, from US$74.0 million in 2012 to US$20.8 million in 2013. This decrease is directly related to the decrease in Yanacocha’s taxable income from 2012 to 2013. Workers’ profit participation expense is calculated based on taxable net income and in accordance with Peruvian labor legislation.

97

The portion of leach pad inventory write-downs associated with costs applicable to sales increased from US$6.5 million in 2012 to US$106.6 million in 2013 due to the decline in the price of gold during the year. As a result of the significant price declines, certain ore on leach pad inventory carrying costs exceeding their net realizable value resulting in a charge to costs applicable to sales.

Depreciation, depletion and amortization

Depreciation, depletion and amortization increased by 32 percent from US$252.9 million in 2012 to US$333.0 million in 2013. This increase was attributable principally to leach pad inventory write-downs combined higher depreciation associated with assets retirements costs and deferred mine development.

Exploration and Advanced project expenses

Exploration costs decreased by 50 percent, from US$40.0 million in 2012 to US$20.0 million in 2013. This decrease was attributable principally to lower exploration regarding the Yanacocha Verde project combined with an overall reduction in district exploration activites.

Advanced projects costs also decreased from US$81.7 million in 2012 to US$44.5 million in 2013. This decline was primarily due to reduced activities associated with the Conga project.

Other expense (net).

Other expense (net) decreased 29 percent or US$32.9 million from 2012 to 2013 primarily due to lower employee serverance program costs incurred in 2013 associated with a program to align Yanaocoha’s organization with future business needs. In addition, lower losses associated with asset sales were incurred during 2013 compared to 2012.

Income tax provision.

Yanacocha’s financial and operating results included income and mining tax expense of US$107.6 million in 2013 compared to US$361.9 million in 2012. The difference was primarily due to Yanacocha’s decreased profitability as the result of lower ounces sold and lower average realized average gold prices received.

Net income.

As a consequence of the foregoing, net income decreased by 77.5 percent, or US$485.5 million, from US$626.5 million in 2012 to US$141.0 million in 2013. As a percentage of sales, net income decreased from 29 percent in 2012 to 10 percent in 2013.

Results of Operations for the Years Ended December 31, 2012 and 2011

Sales

Sales increased by 10 percent from US$2,002.6 million in 2011 to US$2,201.8 million in 2012, due primarily to higher average realized prices combined with an increase in the number of ounces sold. The increase in gold produced in 2012 as compared to 2011 was mainly attributable to an increase of milling activities related to higher volume of tons milled, which was 6.3 million DMT for the year ended December 31, 2012 as compared to 6.2 million DMT for the year ended December 31, 2011, and a higher gold grade and recovery rate of 3.89 grams per ton mined and 87.1%, respectively, for the year ended December 31, 2012 as compared to 2.92 and 82.3%, respectively, for the year ended December 31, 2011. Production by mine was as follows:

98

Mine |  | 2012 |  |  | 2011 |
|  | (ounces) |
Cerro Yanacocha |  |  | 141,038 |  |  |  | 659,996 |
Carachugo |  |  | 698,620 |  |  |  | 319,995 |
Maqui Maqui |  |  | 5,811 |  |  |  | 9,906 |
La Quinua |  |  | 500,524 |  |  |  | 303,226 |
Total |  |  | 1,345,992 |  |  |  | 1,293,123 |

Costs applicable to sales

Costs applicable to sales decreased by 6 percent from 2011 to 2012 due primarily to lower operating costs and lower production taxes, partially offset by higher third-party royalties due to higher sales revenues and lower by-product metal silver and copper sales credit due to lower production. Costs applicable to sales per ounce of gold decreased by 11 percent, from US$581 in 2011 to US$517 in 2012, primarily due to lower direct mining cost per ounce of US$409 in 2012 as compared to US$497 in 2011, lower production taxes per ounce of US$9 in 2012 as compared to US$4 in 2011, partially offset by a lower silver credit per ounce of US$13 in 2012 as compared to US$36 in 2011.

Operating costs decreased by 11 percent from US$618.9 million in 2011 to US$549.9 million in 2012. Operating costs consist primarily of drilling, blasting, loading, hauling and milling costs. These costs decreased in 2012 from 2011 primarily as a result of the capitalization of certain costs associated major mine development costs combined with lower labor costs. The volume of commercial tons mined decreased from 108.7 million DST in 2011 to 51.3 million DST for the year ended December 31, 2012. This decrease is also associated with the mine development program under which a significant amount of tons mined were attributable to development, not commercial activities.

Royalty expense was US$66.6 million in 2012 as compared to US$60.8 million in 2011. The increase in the royalty expense paid to Chaupiloma, which equals 3 percent of Yanacocha’s net sales, was directly related to the increase in Yanacocha’s sales revenues.

Workers’ profit participation increased by 2 percent, from US$72.2 million in 2011 to US$74.0 million in 2012. The increase in workers’ profit participation expense is related to the increase in Yanacocha’s sales revenues. Workers’ profit participation expense is calculated based on taxable net income and in accordance with Peruvian labor legislation. See “Item 4. Information on the Company—Yanacocha—B. Business Overview—Employees.”

Depreciation, depletion and amortization

Depreciation, depletion and amortization increased by 9 percent from US$231.5 million in 2011 to US$252.9 million in 2012. This increase was attributable principally to higher depreciation from inventory variation expenses.

Exploration expenses

Exploration costs, which include advanced projects, increased by 84 percent, from US$66.3 million in 2011 to US$121.7 million in 2012. This increase was attributable principally to increased advanced project activities related to the Conga project, an increased number of exploration works in the Yanacocha area and other regional/oxide development programs.

Other expenses

Other expenses increased by 180 percent, or US$72.5 million, from 2011 to 2012, mainly due to the execution of an employee severance program in order to align Yanacocha’s organization with future business needs, higher regional administration expenses and higher community development and external affairs activities.

99

Income tax provision

The increase in income tax provision was directly related to Yanacocha’s increase in taxable income and the full year impact of the new Peruvian mining and income taxes.

Net income

As a consequence of the foregoing, net income decreased by 2 percent, or US$15.8 million, from US$642.4 million in 2011 to US$626.5 million in 2012. As a percentage of sales, net income decreased from 32 percent in 2011 to 29 percent in 2012.

B. Liquidity and Capital Resources

As of December 31, 2013, Yanacocha had cash and cash equivalents of US$587.0 million, substantially all of which were held in U.S. Dollars, as compared to US$618.1 million as of December 31, 2012.

Cash provided by operating activities

Yanacocha’s operations generated a net cash flow from operations of US$305.7 million in 2013 and US$936.7 million in 2012. The net cash flow from operations in 2013 was 67.4% or US$631.0 million lower than in 2012. The decline was primarily driven by lower sales revenues offset in part by lower sales expenses (royalties), lower workers’ participation costs, reduced advanced projects and exploration activities and lower taxes.

Cash used in investing activities

Net cash used in investing activities was US$336.8 million in 2013 and US$1.117 billion in 2012. In 2012, Yanacocha’s investing activities consisted primarily of US$498 million for engineering, construction and equipment at the Conga project, US$338 million for mine development at El Tapado Oeste, the Western Oxides and the Eastern Oxides, US$30 million for equipment components, US$25 million for water treatment plant studies and construction, US$18 million for gold mill tailings improvements, US$17 million for bio-leach studies and plant construction and US$15 million for the standardization of information technology systems. In 2013, Yanacocha’s principal capital expenditures included US$164 million for engineering, construction and equipment at the Conga project, US$82 million for mine development at El Tapado Oeste, the Western Oxides and the Eastern Oxides deposits, US$21.2 million for equipment components, US$20.7 million for bio-leach studies and plant construction, US$11.8 million for upgrade of Yanacocha Gold Mill plant, US$9.6 million for water treatment plant studies and construction, US$5.9 million for major repairs to the Raw water pond Yanacocha Norte, US$6.2 million for gold mill tailings improvements, US$6.2 million for the standardization of information technology systems, US$3.5 million for Chaquicocha pit development and Other minor projects of US$5.7 million.

Cash used in financing activities

Net cash used in financing activities was US$0 million in both 2013 and 2012. In 2013 and 2012, 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 Yancocha 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.

100

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, 2012 and 2013 and for the years ended December 31, 2011, 2012, and 2013 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. The Cerro Verde Financial Statements for the year ended December 31, 2011 were the first that Cerro Verde 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, Cerro Verde’s transition date 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. The Cerro Verde Financial Statements are prepared and presented in accordance with IFRS as issued by the IASB, which differs in certain respects from U.S. GAAP, as indicated in Note 27 to the Cerro Verde Financial Statements.

A. Operating Results

Overview

We hold a 19.58 percent 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 prior to its privatization in 1993. Freeport-McMoRan Copper & Gold 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 metric ton-per-day concentrator and leaching facilities. Leach-copper production is derived from a 39,000 metric 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, 2011, 2012, and 2013:

Cerro Verde Mining Royalties

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 October 2006 to December 2007 and the years 2008 and 2009. In July 2013, the Peruvian Tax Tribunal issued two decisions affirming SUNAT's assessments for the period October 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. If Cerro Verde is ultimately found responsible for these assessments, it may also be liable for penalties and interest, which accrues at rates that range from approximately 7 percent to 18 percent based on the year accrued and the currency in which the amounts would be payable.

On October 1, 2013, SUNAT served Cerro Verde with a demand for payment totaling 492 million Peruvian nuevos soles (US$176 million based on exchange rates as of December 31, 2013, including interest and penalties of US$104 million) based on the Peruvian Tax Tribunal’s July 2013 decisions for the period October 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. On July 19, 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, 2013, the aggregate amount of the assessments, including interest and penalties, for the year 2009 was 206 million Peruvian Nuevo soles (US$74 million based on exchange rates as of December 31, 2013. SUNAT may make additional assessments for mining royalties and associated penalties and interest for the years 2010 through 2013, which Cerro Verde will contest, No amounts were accrued for these assessments or the installment payment program as of December 31, 2013, because Cerro Verde believes its 1998 stability agreement exempts it from these royalties and believes any payments will 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.

103

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 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 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.

Units of Production (“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.

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 2.3(h) 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 asset retirement cost (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.”

104

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 in order 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 2.3(g) to the Cerro Verde Financial Statements for further discussion.

Contingencies

By their nature, contingencies will only be resolved when one or more future events do or do not occur. Determining contingencies inherently involves the exercise of judgment and calculation of the estimated results of future events

Stripping cost

Cerro Verde 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.

Once Cerro Verde 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., tons) of waste to be stripped and ore to be mined in each of these components.

Results of Operations for the Years Ended December 31, 2013 and 2012

Net sales. Net sales, including mark-to-market adjustments for pounds of copper pending settlement, decreased by 15 percent, from US$2,127.0 million in 2012 to US$1,811.5 million in 2013, principally due to a decrease in average realized copper price during 2013 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, 2012 and 2013:

105

|  | Year ended December 31, |  |  |  |
|  | 2012 |  |  | 2013 |  |  | Variation |
Average price |  |  |  |  |  |  |  |  |  |  |  |
Copper (US$/MT) |  | US$ | 7,965 |  |  | US$ | 7,137 |  |  |  | 10 | %
Volume sold |  |  |  |  |  |  |  |  |  |  |  |
Copper (MT) |  |  | 267,040 |  |  |  | 253,828 |  |  |  | 5 | %

Average realized copper prices per metric ton decreased from US$7,965 in 2012 to US$7,137 in 2013. The volume of copper sold decreased from 267,040 tons in 2012 to 253,828 tons in 2013, due to a decrease in the volume of copper concentrates and copper cathodes sold. The combined effect of these changes resulted in a US$315.6 million decrease in income from sales of copper in 2013 compared to 2012.

Total costs of sales. Total costs of sales increased by 4 percent, from US$765.8 million in 2012 to US$795.1 million in 2013, due mainly to the net effect of the following:

(a) Material and supplies consumption costs decreased by 1 percent, from US$327.3 million in 2012 to US$324.9 million in 2013, mainly due to the decrease in certain materials consumption used in the concentrator process.

(b) Labor costs, including workers’ profit sharing, increased by 21 percent, from US$177.7 million in 2012 to US$215.4 million in 2013, due mainly 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.

(c) The variation of in process inventories decreased from US$32.5 million in 2012 to US$57.9 million in 2013 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 14 percent, from US$95.9 million in 2012 to US$109.3 million in 2013, due mainly to depreciation charges as the level of fixed assets increased (machinary and equipment)

(e) Repair and maintenance services increased by 8 percent, from US$85.4 million in 2012 to US$91.9 million in 2013; and

(f) Energy costs increased by 1 percent, from US$73.1 million in 2012 to US$73.9 million in 2013, mainly due to an increase in the unit cost per kilowatt during 2013.

Total operating expenses. Operating expenses decreased by 37 percent, from US$108.2 million in 2012 to US$68.3 million in 2013, due mainly to changes in the following components:

(a) Selling expenses decreased by 13 percent, from US$78.7 million in 2012 to US$68.4 million in 2013, due mainly to lower copper sales during 2013; and

(b) In 2012 Cerro Verde incurred a charge of US$19.6 million related to expenses associated with the construction of the water treatment plant. No charges were recorded in 2013.

Operating income. As a result of the foregoing, operating income decreased by 24 percent, from US$1,253.0 million in 2012 to US$948.1 million in 2013.

Income tax. Income tax expense, including current and deferred expense, decreased by 27 percent, from an expense of US$454.6 million in 2012 to an expense of US$333.3 million in 2013. Net current income tax expense (including mining taxes)decreased by US$50.9 million due to lower taxable income, and lower deferred taxes decreased by 70.34 million (mainly related to higher deferred expense in 2012 related to the construction of the water treatment plant and mark-to-market adjustments)

106

Net income. As a result of the foregoing, net income decreased by 23 percent, from US$796.6 million in 2012 to US$613.3 million in 2013. As a percentage of net sales, net income was 34percent in 2013, compared with 37 percent in 2012.

Results of Operations for the Years Ended December 31, 2012 and 2011

Net sales. Net sales, including mark-to-market adjustments for pounds of copper pending settlement, decreased by 16 percent, from US$2,520.1 million in 2011 to US$2,127.0 million in 2012, principally due to a decrease in average realized copper price during 2012 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, 2011 and 2012:

|  | Year ended December 31, |  |  |  |
|  | 2011 |  |  | 2012 |  |  | Variation |
Average price |  |  |  |  |  |  |  |  |  |  |  |
Copper (US$/t) |  | US$ | 8,584 |  |  | US$ | 7,964 |  |  |  | (7 | )%
Volume sold |  |  |  |  |  |  |  |  |  |  |  |
Copper (t) |  |  | 293,581 |  |  |  | 267,040 |  |  |  | (9 | )%

Average realized copper prices per metric ton decreased from US$8,584 in 2011 to US$7,965 in 2012. The volume of copper sold decreased from 293,581 tons in 2011 to 267,040 tons in 2012, mainly due to a decrease in the volume of copper cathodes sold. The combined effect of these changes resulted in a US$393.0 million de crease in income from sales of copper in 2012 compared to 2011.

Total costs of sales. Total costs of sales decreased by 7 percent, from US$824.7 million in 2011 to US$765.8 million in 2012, due mainly to the net effect of the following:

(a) Material and supplies consumption costs increased by 4 percent, from US$315.5 million in 2011 to US$327.3 million in 2012, mainly due to the increase in price and quantity of fuel consumption used for the process of waste removal;

(b) Labor costs, including workers’ profit sharing, decreased by 31 percent, from US$256.2 million in 2011 to US$177.7 million in 2012, due mainly to lower workers’ profit sharing to be paid to employees calculated in 2012 as lower income tax basis was obtained;

(c) The variation of in process inventories decreased from US$19.1 million in 2011 to US$32.5 million in 2012 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 14 percent, from US$84.1 million in 2011 to US$95.9 million in 2012, due mainly to an increase in depreciation charges as the level of fixed assets increased;

(e) Repair and maintenance services increased by 15 percent, from US$74.2 million in 2011 to US$85.4 million in 2012; and

(f) Energy costs increased by 6 percent, from US$69.3 million in 2011 to US$73.1 million in 2012, mainly due to an increase in the unit cost per kilowatt during 2012.

Total operating expenses. Operating expenses decreased by 21 percent, from US$136.1 million in 2011 to US$108.2 million in 2012, due mainly to changes in the following components:

(a) Selling expenses decreased by 6 percent, from US$83.6 million in 2011 to US$78.7 million in 2012, due mainly to lower copper sales during 2012; and

(b) Excess of workers’ profit sharing expense decreased from US$21.9 million in 2011 to US$0 million in 2012, due to lower profit and taxable income during 2012.

107

Operating income. As a result of the foregoing, operating income decreased by 22 percent, from US$1,559.3 million in 2011 to US$1,253.0 million in 2012.

Income tax. Income tax expense, including current and deferred expense, decreased by 6 percent, from an expense of US$483.7 million in 2011 to an expense of US$454.6 million in 2012. Net current income tax expense decreased due to lower taxable income, partially offset by (i) higher deferred taxes mainly related to the deduction of costs for construction of the water treatment plant, mark-to-market adjustments and an increase of the effective tax rate from 30% to 32% beginning in 2014 pursuant to the New Tax Stability Agreement executed in July 2012 and (ii) higher mining taxes expense due to new taxes in force since the fourth quarter of 2011.

Net income. As a result of the foregoing, net income decreased by 26 percent, from US$1,078.4 million in 2011 to US$796.6.0 million in 2012. As a percentage of net sales, net income was 37 percent in 2012, compared with 43 percent in 2011.

B. Liquidity and Capital Resources

D. Employees

As of December 31, 2013, we, including our subsidiaries and Coimolache, had 3,773 employees (including 45 employees from our mining trainee program). In addition, we have entered into arrangements with independent contractors which employed 13,570 persons who worked 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, 2013, the average tenure of Buenaventura’s permanent laborers was approximately 10 years.

Of the 2,857 permanent employees employed by Buenaventura and its subsidiaries directly, approximately 43 percent are members of eleven different labor unions (including three unions and one labor union committee for clerical workers and four 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 five years in our mines at Uchucchacua, Antapite, Orcopampa-Poracota, Recuperada and Julcani.

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.

In May and June 2012, we experienced a 15-day work stoppage at our Orcopampa mine due to strikes related to the collective bargaining process with our labor unions and a further 9-day work stoppage at our Orcopampa mine in October 2012 due to a strike by a contract labor union. In 2013 we experienced a strikes at four of our mines. Julcani and Recuperada were affected by a simultaneous strike that lasted 20 days, between April and May. Uchucchacua had a total of 15 days of work stoppage during 2013, most of them related with the contractor´s workers union. Orcopampa was also affected by two strikes, one called by the National Federation of Mining Workers, which lasted one day, and another regarding proper ventilation at our mines, which lasted for 17 days.

114

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 percent of the annual pre-tax profits of their employer, 50 percent of such profits to be distributed based on the number of days each employee worked during the preceding year and the remaining 50 percent 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 the FONDO-EMPLEO, 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 ONP (a public pension fund managed by the state) or in an AFP (private pension funds). We are required to withhold from each of the salaries of the employees enrolled in the ONP system 13 percent 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 percent 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 percent 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 percent of our total payroll for general health services for all permanent employees. Prior to May 1997, we were required to pay to ESSALUD 1 percent of our payroll of blue collar employees for employment-related illness and accidents, or the Workers Compensation Fund Payment. In addition, 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.

The compensation of our key executives (including the related income taxes we assumed in connection therewith) totaled US$32.3 million in 2012 and US$4.7 million in 2013.

Chaupiloma is the legal owner of the mineral rights operated by Yanacocha and receives a 3 percent royalty based on quarterly sales, after deducting refinery and transportation costs. Royalties amounted to US$62.7 million, US$67.2 million and US$44.2 million in 2011, 2012 and 2013, respectively, and are presented as royalty income in our consolidated statements of income.

Condesa did not receive a cash dividend from Yanacocha in 2011, 2012 or 2013.

We received cash dividends from Cerro Verde of approximately US$183.0 million in 2010. We did not receive a cash dividend from Cerro Verde in 2011, 2012 or 2013.

We received cash dividends from Coimolache of approximately US$16.5 million in 2012 and US$9.8 million in 2013.

In March 2002, Buenaventura Ingenieros S.A. 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 an annual fee of US$3.7 million. The revenues for these services amounted to approximately US$4.3 million in each of 2010 and 2011, US$1.7 million in 2012 and US$0.9 million in 2013.

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.

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 dividends will be not less than 20 percent of our net profits. 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 percent of the total Common Shares outstanding can request a dividend of 50 percent 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 percent 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. 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 percent 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 is subject to an additional withholding tax at the rate of 4.1 percent 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. 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 percent to the holders of Common Shares and 0.27 percent 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.

119

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 Nuevos 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 are currently subject to a Peruvian withholding income tax of 4.1 percent. See “Item 10. Additional Information – E. Taxation – Peruvian Tax Considerations.”

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. In order 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. In the event that, 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 2010 to 2013. Dividends with respect to the years 2010 to 2013 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.

122

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 percent of the Common Shares in the first summons and 70 percent 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.

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, 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 percent 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 in the event that 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 by Law No. 30050 in force since June 27, 2013 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.

123

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 percent 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.

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 Superintendencia Nacional de Administración Tributaria (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 in the event that 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 percent 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.

124

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 percent 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, provide that the Board expressly or implicitly refuses to convene the shareholders’ meeting, 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 percent 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. 016-2004-EF/94.10, Resolución CONASEV No. 015-2005-EF/94.10 and Resolución CONASEV No. 078-2010-EF/94.01.1, approved provisions related to the right of the non-controlling shareholders to both obtain information regarding a sociedad anónima abierta such as ourselves and to request the SMV to call a shareholders’ meeting if it is not called by the sociedad anónima abierta upon request. 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.

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 prior to 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 percent 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 percent 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 percent of our total voting shares. For the second call, the presence of shareholders holding at least 25 percent 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 percent and 70 percent 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 respectively. 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.

125

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 percent) of the voting shares of a company, as well as upon any person or group increasing its ownership above the 50 percent and 60 percent thresholds, a procedure known as Oferta Pública de Adquisición, or 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.

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.

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. Prior to 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 percent 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.

126

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 percent 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.

As used herein, “Peruvian holder” means an owner of ADSs or Common Shares that is (i) an individual domiciled in Peru, (ii) a business entity created under the laws of Peru, or (iii) a Peruvian branch, agency or permanent establishment of a non-Peruvian individual or entity. “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 percent over the dividend paid, 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.

Capital Gains

Pursuant to Article 6 of the Peruvian Income Tax Law, or 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, prior to 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 prior to 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) prior to December 31, 2009.

127

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. For non-resident entities or individuals, capital gains will be subject to an Income Tax rate of either 5 percent or 30 percent, depending where the transaction takes place. If the transaction is consummated within Peru, the Income Tax rate is 5 percent; 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.

Prior to 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 percent Corporate Income Tax rate.

Furthermore, prior to 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 five percent 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 (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 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 subsequent to 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.

128

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 percent of value sold), fees payable to the SMV (0.05 percent of value sold), brokers’ fees (about 0.05 percent to 1 percent of value sold) and Value Added Tax (at the rate of 18 percent) 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.

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 percent 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 percent. Dividends paid in Nuevos 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 Nuevos 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.

129

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, or 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 percent of its gross income is passive income or (ii) at least 50 percent of the average value of its assets is attributable to assets that produce passive income or are held for the production of passive income.

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 percent 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.

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$/Nuevo 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, 2014, we had no fixed price commitments for the sale of our metals. As of March 31, 2014, 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, 2014.

131

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 (Nuevos 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 28 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

Fees Incurred in Past Annual Period

From January 1, 2013 to April 30, 2014, 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.

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 deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2013, 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, 2013. In making its assessment, management has utilized the criteria set forth by the Committee of Sponsoring Organizations (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, 2013.

Our independent registered public accounting firm, Medina, Zaldívar, Paredes & Asociados, has issued an attestation report on our internal control over financial reporting, which is included below.

Attestation Report of the 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, 2013, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission “(1992 framework)” - 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 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.

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, 2013, 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, 2013 and 2012, 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, 2013 of Compañía de Minas Buenaventura S.A.A. and subsidiaries and our report dated April 30, 2014, expressed an unqualified opinion thereon.

ITEM 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers

For the year ended December 31, 2013, 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.

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.

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 the accompanying consolidated financial statements of Compañía de Minas Buenaventura S.A.A. (a Peruvian public corporation) and subsidiaries (together the “Group”), which comprise the consolidated statements of financial position as of December 31, 2013 and 2012, 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, 2013, 2012 and 2011, and a summary of significant accounting policies and other explanatory notes. 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 audit. 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.). In the consolidated statements of financial position, the Group’s investment in Minera Yanacocha S.R.L., is stated at US$1,369 and US$1,614 million as of December 31, 2013 and 2012, respectively; and the Group’s equity in the net income of Minera Yanacocha S.R.L. is stated at a loss of US$245 million for the year ended December 31, 2013 and a profit of US$286 and US$308 million for the years ended December 31, 2012 and 2011, respectively. Those statements were audited by other auditors whose report has been 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 report of the other auditors.

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 reports of the other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audit and the reports 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, 2013 and 2012, their results of operations and their cash flows for each of the years ended on December 31, 2013, 2012 and 2011, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB).

F-12

Notes to the consolidated financial statements (continued)

| 2. | Basis for preparation, consolidation and accounting policies

| 2.1. | Basis of preparation -

The consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (hereinafter “IFRS”), as issued by the International Accounting Standards Board (hereinafter “IASB”).

The consolidated financial statements have been prepared on a historical cost basis, except for financial assets and liabilities at fair value through profit or loss, which include the derivative financial instruments, that have been measured at 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 require that Management use judgments, estimates and assumptions, as detailed on the following note 3.

These consolidated financial statements provide comparative information for prior periods.

| 2.2. | Basis of consolidation -

The consolidated financial statements comprise the Group’s financial statements and its subsidiaries to the date of the statements of financial position.

Control is achieved when the Group 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 Group controls an investee if, and only if, the Group has all of the following:

| - | 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.

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 statements of profit or loss and other comprehensive income 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, liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation.

F-13

Notes to the consolidated financial statements (continued)

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

The Group applied, for the first time, certain standards and amendments effective from January 1, 2013. The only rule requiring modification of previously consolidated financial statements is referred to IFRIC 20 Stripping Costs in the Production Phase of a Surface Mine. In addition, the application of IFRS 12 Disclosure of interest in other entities and IFRS 13 Fair value measurement resulted in additional disclosures in the consolidated financial statements.

The nature and the impact of each new standard in the Group is described below:

IFRIC 20 Stripping Costs in the Production Phase of a Surface Mine

The Interpretations Committee issued IFRIC 20 Stripping Costs in the Production Phase of a Surface Mine, effective January 1, 2013. Until December 31, 2012, the Group recorded costs of clearing removal (stripping cost of production) in the production stage as part of the production cost of inventories. As a result of the adoption of IFRIC 20, 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.

IFRS 12 Disclosure of interests in other entities

IFRS 12 sets out the requirements for disclosures relating to an entity’s interests in subsidiaries, joint arrangements, associates and structured entities. The requirements in IFRS 12 are more comprehensive than the previously existing disclosure requirements for subsidiaries. For example, when a subsidiary is controlled with less than the majority of voting rights. IFRS 12 disclosures are provided in note 16.

IFRS 13 Fair value measurement

IFRS 13 establishes a single source of guidance under IFRS for all fair value measurements. IFRS 13 does not change when an entity is required to use fair value but rather provides guidance on how to measure fair value under IFRS. IFRS 13 defines fair value as an exit price.

Application of IFRS 13 has no significant impact to the fair value measurements of the Group. Additional disclosures where required, are provided in the individual notes relating to the assets and liabilities whose fair values were determined. The fair value hierarchy is provided in Note 30.

Notes to the consolidated financial statements (continued)

The following adjustments were made to the consolidated statement of financial position as of December 31, 2012 as a result of the adoption of IFRIC 20:

Impact on the consolidated statements of cash flows

The effect on the consolidated statements of cash flows was an increase in net cash and cash equivalents provided by operating activities of US$25.5 million and an increase in net cash and cash equivalents used in investing activities of US$25.5 million as a higher amount was capitalized to the stripping activity asset during the year.

The net profit for 2011 was restated to reflect the IFRIC 20 adoption by its associate Minera Yanacocha S.R.L., which resulted in a increase of US$14,390,000 with respect to the net profit originally reported in 2011. The Company did not recognize the corresponding effects in its subsidiary El Brocal and its associate Sociedad Minera Cerro Verde S.A.A. because the amounts involved were not material for the profit of such year (net effect of US$45,000).

F-16

Notes to the consolidated financial statements (continued)

| 2.4. | Summary of significant accounting policies –

| (a) | Foreign currency transactions -

The consolidated financial statements are presented in US dollars, which is also the Group’s functional currency. For each unit, 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 balance

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 into the functional currency using the exchange rates prevailing 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 original transactions.

| (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 -

The subsequent measurement of financial assets is classified into 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-17

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 profit or loss. The Group classified as financial assets at fair value through profit or loss its mutual funds at variable income (see note 7).

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 trade and other receivables, net.

Held-to-maturity investments -

Held-to-maturity investments are non-derivative financial assets with fixed or determinable payments and fixed maturities that the Group has the positive intention and ability to hold to maturity. The Group did not maintain any held-to-maturity investment as of December 31, 2013 and 2012.

Available-for-sale financial investments -

The available-for-sale financial investments include investments in shares and debt securities. Equity investments classified as available for sale are those which are not classified as held for trading or are designated as at fair value through profit or loss. Debt securities in this category are those that are thought to have for an indefinite period of time and may be sold in response to liquidity requirements or changes in market conditions. The Group does not have these financial assets as of December 31, 2013 and 2012.

F-18

Notes to the consolidated financial statements (continued)

Derecognition of financial assets -

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, or

| - | 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.

| (ii) | 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 ("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 is discount using the original effective interest rate of the financial asset.

The carrying amount of the asset is reduced through the use of an allowance account and the loss is recognized in the 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-19

Notes to the consolidated financial statements (continued)

| (iii) | 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 and others, 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.

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.

Interest-bearing loans and borrowing -

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.

F-20

Notes to the consolidated financial statements (continued)

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 of financial liabilities -

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.

| (iv) | 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 -

The cash and cash equivalents caption presented in the consolidated statements of financial position includes all cash balances and time deposits, including term deposits with maturities over three months.

For the purpose of the consolidated statements of cash flows, cash and cash equivalents includes cash, short term deposits and high liquidity investments with maturities of three months or less.

| (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.

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).

Classified mineral

The classified ore is placed in tanks to be processed in the medium term until the expansion project of El Brocal’s operations is completed and generally contain lower grade ore than the average ore currently treated. In this sense, the classified mineral is available free to continue the recovery process ores and concentrates.

F-21

Notes to the consolidated financial statements (continued)

According to the mine planning, classified mineral will be treated on the next three years. As consequence, the ore is accounted for as non-current inventory and measured at the lower of cost and net realizable value. Annually, the Company’s Management assess the net realizable value of its non-current inventory based on the cash-flow projections obtained by the production and sales of the low grade ore stockpiled considering to: (i) the forward copper price at the year that to be expected to process the low grade ore, (ii) the future costs of processing (considering inflation rates, technological changes and other significant aspects could change), and (iii) the discount rate.

| (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 it measures the non-controlling interest 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 the administrative expenses caption.

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 the consolidated statements of 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 date acquisition.

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 acquire are assigned to those units.

F-22

Notes to the consolidated financial statements (continued)

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) | 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 neither amortized nor individually tested for impairment.

The consolidated statements 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 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, 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 the consolidated statements of profit or loss.

F-23

Notes to the consolidated financial statements (continued)

| (g) | 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 rehabilitation obligation 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 recognizes such parts as individual assets with specific useful lives and depreciates then accordingly. 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 profit or loss as incurred.

F-24

Notes to the consolidated financial statements (continued)

Depreciation -

Unit-of-production method:

Depreciation of assets directly related to the operation of the mine, whose useful life is greater than the life of the mining unit, is calculated using the units-of-production method, which is based on economically recoverable reserves of the mining unit.

Straight-line method:

Depreciation of assets whose useful life is shorter than the life of the mining unit is calculated using the straight-line method of accounting considering the lower of estimated useful life of the asset or useful life of the mining unit. 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 asset’s residual value, useful lives and methods of depreciation are reviewed at each reporting period, and adjusted prospectively, if appropriate.

Disposal of assets -

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 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.

| (h) | Leases -

The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at the date of inception. The arrangement is assessed to determine whether fulfilment 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.

Finance leases -

Finance leases, which transfer substantially all of the risks and benefits incidental to ownership of the leased item to the Group, 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 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.

F-25

Notes to the consolidated financial statements (continued)

Operating leases -

Operating lease payments are recognized as operating expenses in the statements of profit or loss on a straight-line basis over the lease term.

| (i) | 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 punished 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 the 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.

| (j) | 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 concept 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.

F-26

Notes to the consolidated financial statements (continued)

Development costs necessary to maintain production are expensed as incurred.

| (k) | 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, developmentcosts, 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.

See the impact of the adoption of IFRIC 20 Stripping Costs in the Production Phase of a Surface Mine in note 2.3.

| (l) | 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 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. Where the carrying amount of an asset exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

F-27

Notes to the consolidated financial statements (continued)

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 recoverable amount. 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 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.

| (m) | Share-based payments -

Senior executives of the Group receive remuneration in the form of share appreciation rights, which can only be settled in cash.

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.

| (n) | 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, where 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 financial cost.

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.

F-28

Notes to the consolidated financial statements (continued)

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.

For closed mines, changes to estimated costs are recognized immediately in the consolidated statements of profit or loss.

| (o) | Treasury shares -

Own equity instruments that are reacquired (treasury shares) are recognized at cost and deducted from equity at its nominal amount. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of own equity instruments. Any difference between the carrying amount and the consideration 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.

| (p) | 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 right and taxes. The following specific recognition criteria 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 the goods have passed to the buyer, usually on delivery of the goods.

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.

F-29

Notes to the consolidated financial statements (continued)

Interest revenue -

For all financial instruments measured at amortized cost, interest income or expense 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 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.

F-30

Notes to the consolidated financial statements (continued)

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 costs incurred to date as a percentage of total costs to be incurred by each contract.

| (q) | 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 recognized in the consolidated statements of profit or loss in the period in which they are incurred. Borrowing costs include interest and other costs that the Group incurs in obtaining financing.

| (r) | Taxes –

Current income tax -

Current income tax assets and liabilities for the current period 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 in the countries where the Group operates and generates taxable income.

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 only 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.

F-31

Notes to the consolidated financial statements (continued)

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 rules that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognized outside profit or loss is recognized outside profit or loss. Deferred tax items are recognized in correlation to the underlying transaction either in other comprehensive income or directly in equity.

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 -

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. Both, Mining Royalties and Special Mining Tax generated deferred assets and liabilities on the same basis as described above for other forms of taxation.

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.

| (s) | Fair value measurement

The Group measures its financial instruments, such as, derivatives, embedded derivatives, mutual funds, at fair value at the date of the consolidated statements of financial position.

F-32

Notes to the consolidated financial statements (continued)

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.

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.

| (t) | Derivative financial instruments and hedging accounting -

Initial recognition and subsequent measurement –

The subsidiary 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.

At the inception of the hedge relationship, El Brocal formally designates and documents the hedge relationship to which El Brocal wishes to apply hedge accounting, and the risk management objective and strategy for undertaking the hedge.

F-33

Notes to the consolidated financial statements (continued)

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.

El Brocal’s hedge is classified as cash 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.

| 3. | Significant judgements, 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. 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.

The Group has identified the following areas where significant judgments, estimates and assumptions are required. 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.

Judgements

In the process of applying the Group’s accounting policies, management has made the following judgements, which have the most significant effect on the amounts recognized in the consolidated financial statements:

| (a) | Contingencies (note 25) -

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 costs (note 2.4(k)) –

The Group 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. Significant judgement is required to distinguish between development stripping and production stripping and to distinguish between the production stripping that relates to the extraction of inventory and what relates to the creation of a stripping activity asset.

Once the Group 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.

F-34

Notes to the consolidated financial statements (continued)

| (c) | 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.

| (d) | 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.

| (e) | Recovery of deferred tax assets - (note 24) -

Judgement is required to determine whether deferred tax assets are recognized in the consolidated statements of financial position. Deferred tax assets, including those arising from unused tax losses, require Management to assess the likelihood that the Group will generate sufficient taxable earnings in future periods, in order to utilize recognized deferred tax assets. Estimates of future taxable income are based on forecast cash flows from operations and judgement about the application of existing tax laws. To the extent that future cash flows and taxable income differ significantly from estimates, the ability of the Group to realize the deferred tax assets recorded at the reporting date could be impacted.

Additionally, future changes in tax law in the jurisdictions in which the Group operates could limit the Group to obtain tax deductions in future periods.

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.

F-35

Notes to the consolidated financial statements (continued)

| (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.

F-36

Notes to the consolidated financial statements (continued)

| (b) | Units of production depreciation (note 2.4(g)) -

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 (note 2.4(n) and note 13(b)) -

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 (note 9) -

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.

The deposits of low-grade ore mined from the Colquijirca mining unit are measured by estimating the number of tons added and removed, the number of contained metal tons is based on assay data, and the estimated recovery percentage is based on the expected processing method.

| (e) | Recoverability of assets (note 2.4(l) and note 11(b)) -

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.

The Group has determined the operations of each mining unit as a single cash generating unit.

F-37

Notes to the consolidated financial statements (continued)

| (f) | Share-based payments (note 2.4(m) and note 13(d)) -

The Group measures the cost of their benefits in shares paid in cash to employees by reference to the fair value of the equity instruments at the grant date. The estimated fair value of share- based payments requires determination of the most appropriate inputs to the valuation model, which is dependent on the terms and conditions of the grant. This estimate also requires determination of the most appropriate inputs to the valuation model, including the expected life of the stock option, volatility and dividend yield and making assumptions about them.

| 4. | Standards issued but not effective -

At the date issued of the consolidated financial statements, there is only one standard that applies to the Group that is issued, but not yet effective:

IFRS 9 Financial Instruments -

This standard is effective for annual periods beginning on or after January 1, 2018. IFRS 9 reflects the first phase of the IASB’s work on the replacement of IAS 39 and applies to classification and measurement of financial assets and financial liabilities, as defined in IAS 39. The adoption of the first phase of IFRS 9 may have an effect on the classification and measurement of the Group´s financial assets but it will not have an impact on classification and measurement of the Group´s financial liabilities. In subsequent phases, the IASB will address hedge accounting and impairment of financial assets.

| 5. | Transactions in Nuevos Soles

Transactions in Nuevos Soles are completed using exchange rates published by the Superintendent of Banks, Insurance and AFP. As of December 31, 2013, the exchange rates for U.S. dollars published by this Institution were US$0.3579 for buying and US$0.3577 for selling (US$0.3923 for buying and US$0.3920 for selling as of December 31, 2012) and have been applied by the Group for the assets and liabilities accounts, respectively.

As of December 31, 2013 and 2012, the Group had the following assets and liabilities denominated in Nuevos Soles:

Bank accounts earn interest at floating rates based on market rates.

As of December 31, 2012, time deposits had different maturities (between 5 and 13 days), and earned interest at market rates.

| 7. | Financial assets at fair value through profit or loss

The Group’s Management used to keep excess cash in mutual funds at variable income, managed by a financial entity of first level, which were designated as financial assets at fair value through profit or loss.

These funds were made up by a portfolio of commercial papers issued by the Peruvian Government and by reputable financial entities.

As of December 31, 2013, the Group liquidated the total amount of the fund (US$54,509,000 as of December 31, 2012).

During the year 2013, the Group recorded a decrease of US$1,565,000 (increases by US$2,331,000 and US$2,024,000, during the years 2012 and 2011, respectively), to bring the investments at their fair value.

The allowance for doubtful accounts showed no movement during the years 2013, 2012 and 2011. In the opinion of management of the Group, the allowance for doubtful accounts is enough to cover the risk of default to the date of the consolidated statements of financial position. Accounts receivable past due but not impaired are within normal ranges in the industry, and are related to the provisional billings pending final settlement.

Final balance |  |  | 6,647 |  |  |  | 3,244 |  |  |  | 3,053 |

In December 2013, the subsidiary El Brocal recognized a provision for impairment of 180,072 DMT of mineral (type I). Based on the technical reviews performed by the management of this subsidiary, this mineral cannot be economically treated and sold.

In the opinion of Group’s management, the provision for impairment of value of inventory adequately covers this risk as of the date of the consolidated statements of financial position.

In 2013, Minera Yanacocha S.R.L. (hereinafter "Yanacocha") recorded an impairment charge of its long-lived assets of approximately US$726,985,000, net of tax, which reduced the net equity of Yanacocha and, therefore, the equity of the Group in this associate. This decline resulted from the significant drop in the prices of gold and silver compared to the averages obtained in previous years, lower grades to be obtained from mature deposits, the natural depletion of reserves, and higher costs to be incurred in order to obtain the social license to operate the Conga project.

Investments in Yanacocha –

Yanacocha is engaged in gold production and exploration and development of gold and copper in their own concessions or owned by S.R.M.L. Chaupiloma Dos de Cajamarca, with which signed a contract of use of mineral rights.

During the last several years, Yanacocha is developing the Conga project, which consists in 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). As of April 17, 2012, the independent experts hired by Peruvian Government, issued the international report on water component of the environmental impact study for Conga mining project, which validates, essentially, the environmental impact study approved in 2010 and includes recommendations for improvement. On June 22, 2012, Yanacocha’s management approved the recommendations made by independent experts. As a result, Yanacocha’s management has reprogrammed the development activities, focusing on recommended water sustainability activities. Currently, the development of Conga is contingent upon generating acceptable project returns and getting local community and government support. Should Yanacocha be unable to continue with the current development plan at Conga, Yanacocha may in the future reprioritize and reallocate capital to development alternatives in other sites, which may result in an impairment of the Conga project.

Summary of significant differences between U.S. GAAP followed by Yanacocha and IFRS used by the Group for its consolidated financial statements:

| (i) | Impairment of property, plant and equipment –

The decline in gold, copper and silver prices was deemed to be indicator of a potential impairment of the long-lived assets of Yanacocha and Conga. Consequently, Yanacocha performed an impairment assessment as of December 31, 2013. The difference between U.S. GAAP and IFRS is originated by the use of discounted future cash flows for IFRS while for U.S. GAAP Yanacocha used undiscounted future cash flows.

F-44

Notes to the consolidated financial statements (continued)

| (ii) | Asset Retirement Obligation (ARO) –

Under IFRS, provisions are adjusted at each statement of financial position to reflect the current best estimate. If the provision was discounted, the provision should increase in each period to reflect the passage of time. The interest rate used to measure that change is a rate that reflects current market assessments of the time value of money and the risks specific to the liability as of each statement of financial position date.

Under U.S. GAAP, changes to an ARO due to the passage of time are measured by applying an interest method of accretion to the amount of the liability at beginning of the period. The interest rate used to measure that change is the credit-adjusted risk free rate that existed when the liability, or portion thereof, was initially measured.

| (iii) | Stripping Activity Asset -

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.

| (iv) | Deferred income tax for IFRS adjustments –

The various reconciliation items lead to different temporary differences. Yanacocha accounted for such differences according to its tax and accounting policies.

Notes to the consolidated financial statements (continued)

| (b) | During the years 2013 and 2012, the Group recognized impairment losses of certain assets by US$6,594,000 and US$3,617,000, respectively, as a result of the decrease in the level and quality of reserves of the mining units Poracota, Recuperada, Shila-Paula and Antapite. The recoverable amounts were determined based on their values in use and were calculated at each mining unit. The discount rate used, before taxes, was 6.21 percent. Management believes that there will not be significant changes in the discount rate that may increase the impairment loss.

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 2014 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, 2013, the future value of the provision for closure of mining units and exploration projects was US$183,756,000, which has been discounted using the annual risk-free rates ranging from 0.79 to 2.65 percent in periods of 1 to 27 years, resulting in an updated liability of US$145,213,000 (US$99,438,000 as of December 31, 2012). The Group believes that this liability is sufficient to meet the current environmental protection laws approved by the Ministry of Energy and Mines.

The Group has constituted letters of credit in favor of the Ministry of Energy and Mines for US$74,486,000 (US$46,608,000 as of December 31, 2012) to secure mine closure plans of its mining units.

| (c) | Workers’ profit sharing -

Legislative Decree N° 892 (L.D. 892), issued in 1996, regulates the right of workers to participate in the profits of companies that obtain taxable income. Under this legislative decree, companies domiciled in Peru have to compute and pay to their employees a share of the profits generated by such companies.

The workers’ profit sharing is recorded as a production cost or administrative expense according to the duties or function of the workers.

The workers’ profit sharing is paid with a limit of 18 salaries. The excess is retained by the Group and this is paid to Peruvian Government entities (FONDOEMPLEO and regional government). During the year 2013, the excess between the total amounts of workers’ profit sharing calculated in accordance to D.L. 892 and the limit to pay to employees amounts to US$704,000 in the year 2013 (US$2,164,000 in the year 2012 and US$6,221,000 in the year 2011), which will be transferred to FONDOEMPLEO or the regional government within the period established by law. Based on the Group’s accounting policy, such excess is shown as operating expenses in the consolidated statements of profit or loss.

| (d) | Stock appreciation rights -

Senior executives of the Group are granted share appreciation rights, which can only be settled in cash, if the executive is working for the Group at each program’s settlement date. These programs are mainly structured in a 10-year term, allocated in several programs with progressive maturities. The settlement of each program is determined based on the variation of the market prices at the maturity date as compared to the price at the date of the grant, over the corresponding number of shares.

The table below presents the main assumptions used by the Group to estimate the fair value:

|  | 2013 |  |  | 2012 |
Historical volatility |  |  | 47.69 | % |  |  | 48.38 | %
Risk-free interest rate for the remaining period until vesting |  |  | 0.00 | % |  |  | 0.16 | %
Dividend yield |  |  | 1.29 | % |  |  | 1.25 | %
Period covered by the program |  |  | 10 years |  |  |  | 10 years |

(*) Value added tax, from 2010 to 2013.

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, 2013 and 2012.

The open tax process of the Group and its associates are presented in Note 25.

| (c) | Tax-loss carryforwards –

Buenaventura -

As of December 31, 2013 and 2012, the tax-loss carryforward determined by Buenaventura amounts to approximately S/.169,525,000 and S/.279,857,000, respectively (equivalent to US$60,631,000 and US$100,092,000, respectively). In November 2010, the Company filed an amended income tax return of 2009 which increased the tax-loss carryforward. As permitted by the Income Tax Law, Buenaventura has chosen a system that permits to offset this loss with an annual cap equivalent to 50 percent of net future taxable income.

Buenaventura has decided to recognize a deferred income tax asset as it is more likely than not that the tax-loss carryforward can be used to offset future taxable income.

F-67

Notes to the consolidated financial statements (continued)

El Brocal -

As of December 31, 2013, the tax-loss carryforward amounts to S/.11,537,000 (equivalent to US$4,126,000). As permitted by the income tax law, El Brocal has opted to use such loss against the taxable income to obtain during the next four years after the year of generation.

El Brocal has decided to recognize a deferred income tax asset as it is more likely than not that the tax-loss carryforward can be used to offset future taxable 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, 2013 and 2012.

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.

In compliance with the above-mentioned laws, the Ministry of Energy and Mines (MEM) approved PAMA which were presented by the Group for its mining units and exploration projects. The Group performs revisions to the initial plans presented to MEM, which are then sent for its approval.

The Group considers that the recorded liability (see note 13 (b)) is sufficient to meet the current regulatory environment in Peru.

Yanacocha -

Mercury spill in Choropampa

In June 2000, a transport contractor of Yanacocha spilled approximately 151 kilograms of elemental mercury near the town of Choropampa, Peru, which is located 53 miles (85 kilometers) southwest of the Yanacocha mine. Mercury is a residue of mining gold. After the spill, Yanacocha implemented a comprehensive program of remediation of health and the environment. In August 2000, Yanacocha paid under protest a fine of S/.1.7 million (approximately US$0.5 million) to the Peruvian Government (MEM).

Yanacocha has entered into settlement agreements with people affected by the incident. In addition, it has agreed with three of the communities affected by the incident in the execution of a series of public works as a compensation for the inconvenience and disruption caused by the incident.

F-77

Notes to the consolidated financial statements (continued)

In May 2002, additional lawsuits related to the incident in Choropampa have been filed in two local courts in the city of Cajamarca, Peru, over 900 Peruvian citizens. Yanacocha has made settlement agreements with a significant number of people before the legal claims arise. In April 2008 the Supreme Court ruled the validity of these agreements, which means that all those cases in which the plaintiffs signed prior to their claim settlement agreements will be rejected by the judiciary (about 350 applicants).

Since December 2010 to date, 23 new claims involving 29 plaintiffs were received by Yanacocha. In these claim, plaintiffs are requesting the Judge to (i) declare void the compensation agreement signed with Yanacocha and to (ii) award them with new compensation amounts. Two of these new claims involving two plaintiffs were dismissed as they did not comply with formal requirements. In 19 of these cases, the initial presiding judge admitted a motion to dismiss based on prescription of the actions and dismissing the processes. Plaintiffs appealed this decision, and Superior Court confirmed it in 18 cases. In 8 of these cases, plaintiffs have challenged this decision in front of the Supreme Court, but to date one of them has already been dismissed. In one of the claims, a different presiding judge accepted Yanacocha’s motion to dismiss the claim regarding a new award but it has rejected it regarding the compensation agreement, this decision was confirmed by Superior Court, so this claim continues in first instance. Both request (i) and (ii) were prescribed according to the terms in Peruvian legislation, so those claims should be dismissed.

Yanacocha cannot reasonably predict the outcome of any of the claims described above. It is estimated that the maximum additional expense related to these demands will be US$1.5 million as of Decemeber 31, 2013 and 2012.

Baños del Inca

In September 2006 the Municipality of Baños del Inca issued a declaration designating an area that includes the Carachugo Expansion and San Jose Projects as reserved and protected areas. Based on previous experience and actions taken by the Constitutional Tribunal (Peru Court of Last instance for Constitutional issues) in respect of Cerro Quilish in which it was ruled that such declaration did not affect Yanacocha’s mining rights, Yanacocha believes that Baños del Inca’s declaration, should not impact the Yanacocha’s legal rights to exploit these concessions.

The legal proceeding is currently pending resolution in Lima’s Court of First Instance.

In March 2008, the Lima Court rejected a Baños del Inca Municipality request which did not recognize its Jurisdiction. This process is pending resolution.

San Pablo

In February 2007 the Municipality of San Pablo issued an ordinance designating an area that includes Las Lagunas and Pozo Seco as reserved and protected areas, where Yanacocha has mining rights. Based on previous experience and actions taken by the Constitutional Tribunal in respect of Cerro Quilish in which it was ruled that such declaration did not affect Yanacocha’s mining rights, Yanacocha believes that San Pablo’s declaration, should not impact Yanacocha’s legal rights to exploit these concessions. Yanacocha has challenged this ordinance on the grounds that, under Peruvian law, local governments lack the authority to create such areas, denying the rights granted by Yanacocha’s mining concessions. The Court in the First Instance rejected the complaint based on formal grounds. The resolution of the Court was appealed before Lima’s Court of Second Instance.

In November 2008, Lima’s Court affirmed the ruling from the first instance. In December 2011, Constitutional Court accepts the complaint. The process is currently pending resolution.

Clínica Internacional, Addeco, SDC Security

Workers of three contractors companies (Clínica Internacional, Adecco and SDC Security) have initiated judicial proceedings through which they demand their incorporation into Minera Yanacocha’s payroll. The workers deem they are direct employees of Yanacocha with all the rights, arguing that they receive direct orders from Minera Yanacocha and that most of the equipment they use is given by Yanacocha. All proceedings, which involve a total of 85 workers, are pending first instance resolution.

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. The project has proven and probable reserves of 12.6 million ounces (unaudited) of contained gold and 3.3. billion pounds (unaudited) of contained copper at December 31,2013.

Due to local political and community protests, construction and development activities at the Conga project were largely suspended in November 2011. The result of the Peruvian Central Government initiated Environmental Impact Assessment (“EIA”) independent review were announced on April 20, 2012 and confirmed the initial EIA met Peruvian and International Standars. The review made recommendations to provide additional water capacity and social funds, which Yanacocha has largely accepted. Yanacocha announce the decision to move the project forward on a “water-first” approach on June 22, 2012. During 2013, the project focused on building water reservoirs, completing the last engineering activities, and accepting delivery of the main equipment purchases.

If Yanacocha is unable to continue with the current development at conga, we may reprioritize and reallocate capital to other development alternatives. If the project proceeds, average annual estimated gold production of approximately 580 to 680 thousand ounces of gold per year and production of 155 to 235 million pounds per year are expected during the first five years of production. As of December 31, 2013, Yanacocha reported 12.6 million ounces of gold reserves and 3.3.billion pounds of copper reserves.

In the second quarter of 2011, Presidential and Congressional elections resulted in a change in government in Peru. The new administration supported mining as a driver for continued growth and future development of Peru. However, we are unable to predict whether the Central government will continue to take similar positions in the future. The regional government actively opposed the Conga project in 2012 and continues to reject the viability of its development. We are unable to predict the positions that will be taken in the future and whether such positions or changes in law will affect Yanacocha or Conga. Such changes may include increased labor regulations, environmental and other regulatory requirements, and additional taxes and royalties, as well as future protests, community demands and road blockages. For example, during the third quarter of 2011, the new government enacted four new tax laws. T Yanacocha cannot predict future positions of either the central or regional government of 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 Yanacocha or Conga, which could have a material adverse effect on our results of operations and financial position. Additionally, any inability to continue to develop the Conga project or operate at Yanacocha could have an adverse impact on our growth if we are not able to replace its expected production. To help insure the viability of Yanacocha’s mining activities, Yanacocha has an active community relations program focused on Cajamarca water projects, education and health. In addition, Conga is building reservoirs under its “water-first” approach in effort the gain social acceptance.

| (e) | Open tax procedures –

Buenaventura -

In 2007, Buenaventura was audited by the tax authorities for income tax of 2005. As a result, the tax authority did not recognize certain deductions declared for S/.119,785,000 (equivalent to US$43,042,000). The main objection consisted in considering as taxable income the reversal of the provision related to commercial contracts, which originally was not deducted to calculate the Income Tax. In July 2013, the Tax Court resolved the assessment made by the Tax Administration, concluding the case through a payment of approximately US$705,000.

During 2012 and 2013 the tax authorities audited the income tax of 2007. As a result, they did not recognize Buenaventura declared deductions by S/.1,076,071,000 (equivalent to US$384,861,000). The main unrecognized deduction by Buenaventura 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.

Also, in March 2013, the Tax Administration has initiated the audit of the 2008 income tax and the value added tax for the period January to December 2008.

Subsidiaries –

CEDIMIN

The income tax of Cedimin of 2002 was audited by the tax authorities. As a result, they do not recognize to Cedimin the declared tax loss carryforward. The main controversy consists on making deductible the loss on the sale of shares in Minera Huallanca S.A.C. and Minera Yanaquihua S.A. for S/.22,041,000 (US$7,883,000). In Management's and its legal counsel’s opinion, that interpretation has no support so Cedimin should get a favorable outcome in the appeal initiated against the tax authorities.

El Brocal

At the date of this report, the Tax Administration is reviewing the Income Tax return of 2011.

Associates -

Cerro Verde

|  | On June 23, 2004, Law No.28258 - Mining Royalty Law was approved, and requires the holder of a mining concession to pay a royalty in return for the exploitation of metallic and non-metallic minerals, which is calculated using rates from one to three percent of the value of concentrate or its equivalent according to the international price of the commodity published by the Ministry of Energy and Mines.

Based on the 1998 stability agreement described above in letter (a), the payment of the mining royalties was not applicable to Cerro Verde since this contribution was created after Cerro Verde signed the stability contract with the Peruvian Government.

The Peruvian tax authority (SUNAT) has assessed mining royalties on materials processed by Cerro Verde’s concentrator, which commenced operations in late 2006. Such assessments cover the period from October 2006 to December 2007, as well as years 2008 and 2009. SUNAT has issued resolutions rejecting the claims of Cerro Verde. Cerro Verde has appealed such decisions before the Tax Court. On July 23, 2013, SUNAT notified the final decision of the Tax Court confirming the assessments for the periods October to December 2006, and for the years 2007 and 2008. By means of the decision of the Tax Court, the administrative stage for the appeal of these proceedings ends.

F-80

Notes to the consolidated financial statements (continued)

In September 2013, Cerro Verde filed judiciary appeals to Judiciary Court (Civil Court of the Superior Court of Arequipa) suing SUNAT, the Ministry of Energy and Mines and Tax Court for requiring Cerro Verde to pay mining royalties during the term of the stability agreement in force until 31 December 2013. Cerro Verde believes that the Stability Agreement entered into with the Peruvian government in 1998 (which was in force from January 1, 1999, to December 31, 2013) guarantees that all minerals extracted from their production unit are included in the stabilized tax and administrative regime, which does not include the obligation to pay the Mining Royalty.

On October 1, 2013, SUNAT issued a payment order by 492 million of Nuevos Soles (US$176 million based on current exchange rates, including interest and penalties of US$104 million). As permitted by law, Cerro Verde requested and as has been granted an installment payment program that defers payment for six months and thereafter satisfies the amount via 66 equal monthly payments. In July 2013, a claim on SUNAT’s assessment for 2009 was rejected, but no final decision has been issued by the Tax Court for that year.

In Cerro Verde Management’s and legal advisors’ opinion, Cerro Verde has sound legal grounds; consequently, it believes any payments will be recoverable.

Terms and conditions of transactions with related parties

Purchase transactions and services with related parties are made at market prices. Outstanding balances at year end are unsecured and interest free and settlement occurs in cash. There have been no guarantees provided or received for any related party receivables or payables. For the year ended December 31, 2013 and 2012, the Group has not recorded any impairment of receivables related to owed by related parties. This assessment is undertaken each financial year through examining the financial position of the related party and the market in which it operates.

| 27. | Disclosure of information on segments

IFRS 8 – “Operating Segments” requires that companies present financial information taking into account the information reported that the chief operating decision maker uses internally for evaluating the performance of operating segments and allocating resources to those segments (a “through the eyes of management” approach).

The Group’s only reportable segment that meets the threshold for reporting is mining. These activities are executed through sixteen companies. The Group’s Management considers that these companies could be combined in one segment (mining) considering the financial performance and similar characteristics related to goods nature, production process nature, type of clients and legal environment. The electric segment, mining consulting and insurance are not significant in order to evaluate business development; for this reason, management considers the mining segment as the only reportable segment.

The Board of Directors has been identified as the body responsible for approving the Group's operational decisions. Moreover, it is responsible for allocating resources and assessing performance as a single operating unit.

| 28. | Derivative financial instruments

| (a) | The volatility of copper during this year has caused the management of the subsidiary El Brocal to enter into future contracts. These contracts, which have been negotiated since August 8, 2013, 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.

F-84

Notes to the consolidated financial statements (continued)

The contracts seek to eliminate the volatility of the copper price from September 2013 to December 2014, according to the existing sales commitments of cooper concentrate, which are related to 25 percent of the annual production of such metal (50 percent from 2014).

As of December 31, 2013, the fair value of futures contracts amounted to a liability of US$1,093,000. The debit, net of the deferred income tax, amounted to a negative balance of US$715,000 and is presented as other reserves of equity in the consolidated statements of changes in equity (net liabilities of US$844,000 and net assets of US$17,076,000 for the years ended December 31, 2012 and 2011, respectively).

| (b) | Embedded derivative for the change in prices in the interim trade settlements -

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, 2013 and 2012. 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 Buenaventura and El Brocal as of December 31, 2013 are:

| 29. | 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, 2013, 2012 and 2011.

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.

The sensitivity analysis in this section relate to the positions as of December 31, 2013, 2012 and 2011, and have been prepared considering that the proportion of financial instruments in foreign currency are constant.

F-86

Notes to the consolidated financial statements (continued)

| (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 Nuevos Soles. The Group mitigates the effect of exposure to exchange-rate risk by carrying out almost all of its transactions in its functional currency. Management has smaller amounts in Nuevos Soles in order to cover its needs (taxes and compensation) in this currency.

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) |
2013 |  |  |  |  |  |  |  |
Exchange rate |  |  | +10 | % |  |  | 20,989 |
Exchange rate |  |  | -10 | % |  |  | (25,225 | )
2012 |  |  |  |  |  |  |  |
Exchange rate |  |  | +10 | % |  |  | 8,854 |
Exchange rate |  |  | -10 | % |  |  | (10,563 | )
2011 |  |  |  |  |  |  |  |
Exchange rate |  |  | +10 | % |  |  | 8,638 |
Exchange rate |  |  | -10 | % |  |  | (10,333 | )

| (a.2) | Comodity 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.

F-87

Notes to the consolidated financial statements (continued)

| (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´s long-term financial obligations with floating interest rates.

A table showing the effect in profit or loss of the variations of interest rates:

| (b) | Credit risk-

Credit risk is the risk that a 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 18(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.

- Embedded derivative financial instruments, net |  |  | 4,939 |  |  |  | - |  |  |  | 4,939 |  |  |  | - |

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, 2013 and 2012.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

| 1. | BUSINESS ACTIVITIES

Minera Yanacocha S.R.L. (the “Company, we or our”), formerly Minera Yanacocha S.A., 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 owned 51.35% by Newmont Second Capital Corporation, a 100% indirectly owned subsidiary of Newmont Mining Corporation (“Newmont”), 43.65% owned by Compañía Minera Condesa S.A., which is 100% owned by Compañía 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 effective January 1, 1994, the Company pays Chaupiloma a 3% royalty based on quarterly production sold at current market prices, after deducting refinery and transportation costs. The royalty agreement expires in 2032.

The Company’s operations are located near Cajamarca, province of Peru and currently include the following open pit mines: Cerro Yanacocha, La Quinua (which includes El Tapado Oeste), Chaquicocha, Maqui Maqui, Carachugo, Marleny and Cerro Negro. 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 flow 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 2013, 2012 and 2011, the Company produced 1.02 million, 1.35 million and 1.29 million ounces of gold, respectively.

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. The project has proven and probable reserves of 12.6 million ounces (unaudited) of contained gold and 3.3 billion pounds (unaudited) of contained copper at December 31, 2013.

Due to local political and community protests, construction and development activities at the Conga project were largely suspended in November 2011. The result of the Peruvian Central Government initiated Environmental Impact Assessment (“EIA”) independent review were announced on April 20, 2012 and confirmed the initial EIA met Peruvian and International standards. The review made recommendations to provide additional water capacity and social funds, which the Company accepted. The Company announced the decision to move the project forward on a “water first” approach on June 22, 2012. During 2013 the project focused on building water reservoirs, completing the last engineering activities, and accepting delivery of the main equipment purchases.

Should the Company be unable to continue with the current development at Conga, we may reprioritize and reallocate capital to development alternatives. Should the project proceed, average annual estimated gold production of approximately 580 to 680 thousand ounces of gold per year and attributable production of 155 to 235 million pounds of copper per year are expected during the first five years of production.

In the second quarter of 2011, Presidential and Congressional elections resulted in a change in government in Peru. The new administration supported mining as a driver for continued growth and future development of Peru in 2012. However, we are unable to predict whether the Central government will continue to take similar positions in the future. The regional government actively opposed the Conga project in 2012 and continues to reject the viability of its development. We are unable to predict the positions that will be taken in the future and whether such positions or changes in law will affect Yanacocha or Conga. Such changes may include increased labor regulations, environmental and other regulatory requirements, and additional taxes and royalties, as well as future protests, community demands and road blockages. For example, during the third quarter of 2011, the new government enacted four new tax laws. The Company cannot predict future positions of either the Central or regional government on foreign investment, mining concessions, land tenure or other regulations. Any change in government positions or laws on these issues could adversely affect the assets and operations of Yanacocha or Conga, which could have a material adverse effect on our results of operations and financial position.

Total proven and probable reserves (unaudited) contained in active open pits, other pits to be developed, stockpiles, ore in process on leach pads and the Conga project are approximately 18.4 million ounces of contained gold, 3.3 billion pounds of contained copper and 37.1 million ounces of silver at December 31, 2013.

| 2. | SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The Consolidated Financial Statements include the accounts of Minera Yanacocha S.R.L and the San José Reservoir Trust (“Trust”). In November 2008, the Company funded the Trust to ensure continuous operation of the San José Reservoir after 2018. The Company transferred $13,000 to the Trust in 2008. No withdrawals are allowed until 2018 and the Company is committed to a $23,000 fund as of that date. This Trust is irrevocable and is a separate legal entity. The grantor is the Company, the trustee is the FiduPerú S.A. Sociedad Fiduciaria and the beneficiary is the Company; therefore, the Company consolidates the Trust in its Consolidated Financial Statements.

Use of Estimates

The Company’s Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of the Company’s Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production amortization calculations; environmental, reclamation and closure obligations; estimates of recoverable gold and other minerals in stockpile and leach pad inventories; write-downs of inventory, ore on leach pads and stockpiles to net realizable value; employee benefit liabilities; valuation allowances for deferred tax assets; workers’ profit participation; reserves for contingencies and litigation; and the fair value and accounting treatment of financial instruments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may differ significantly from these estimates under different assumptions or conditions.

(dollars in thousands unless otherwise stated)

Currency

The Consolidated Financial Statements are stated in U.S. dollars, the Company’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.

Cash and Cash Equivalents

Cash and cash equivalents consist of all cash balances and highly liquid investments with an original maturity of three months or less. Because of the short maturity of these balances, the carrying amounts approximate their fair value. Restricted cash is excluded from cash and cash equivalents and is included in other current assets or long-term assets depending on the applicable restrictions.

Investments

Management determines the appropriate classification of its investments in equity securities at the time of purchase and reevaluates such determinations at each reporting date. The Company accounts for its marketable security investments as available for sale securities in accordance with FASB Accounting Standards Codification (“ASC”) guidance on accounting for certain investments in debt and equity securities. The Company periodically evaluates whether declines in fair values of its investments below the Company’s carrying value are other-than-temporary in accordance with ASC guidance. The Company’s policy is to generally treat a decline in the investment’s quoted market value that has lasted continuously for more than six months as other-than-temporary decline in value. The Company also monitors its investments for events or changes in circumstances that have occurred that may have a significant adverse effect on the fair value of the investment and evaluates qualitative and quantitative factors regarding the severity and duration of the unrealized loss and the Company’s ability to hold the investment until a forecasted recovery occurs to determine if the decline in value of an investment is other-than-temporary. Declines in fair value below the Company’s carrying value deemed to be other-than-temporary are charged to 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:

F-100

MINERA YANACOCHA S.R.L.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

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 amortization relating to mining operations, and removed at each stockpile’s average cost per recoverable unit.

Ore on Leach Pads

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, 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.

In-process Inventory

In-process inventories represent materials that are currently in the process of being converted to a saleable product. The 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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

Precious Metals Inventory

Precious metals include gold dore and/or gold bullion. Precious metals that result from the Company’s mining, processing and refining activities are valued at the average cost of the respective in-process inventories incurred prior to the refining process, plus applicable refining costs.

Materials and Supplies

Materials and supplies are valued at the lower of average cost or net realizable value. Cost includes applicable taxes and freight.

Property, Plant and Mine Development

Facilities and Equipment

Expenditures for new facilities or equipment and expenditures that extend the useful lives of existing facilities or equipment are capitalized and recorded at cost. The facilities and equipment are amortized using the straight-line method at rates sufficient to amortize such costs over the estimated productive lives of such facilities. These estimated productive lives do not exceed the related estimated mine lives, which are based on proven and probable reserves.

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 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 minims saleable materials may occur during development and are recorded as Other income, net of incremental mining and processing costs.

F-102

MINERA YANACOCHA S.R.L.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

The production phase of an open pit mine commences when saleable minerals, beyond a de minims 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. The Company’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.

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. 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.

Asset Impairment

The Company 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. The Company’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.

Revenue Recognition

Revenue is recognized, net of treatment and refining charges, from a sale when persuasive evidence of an arrangement exists, the price is determinable, the product has been delivered, the title has been transferred to the customer and collection of the sales price is reasonably assured. Revenues from silver and copper sales are credited to Costs applicable to sales as a by-product credit.

Income and Mining Taxes and Profit Sharing

The Company 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 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 and profit sharing liability or net deferred income tax asset and profit sharing asset for the Company, as measured by the statutory tax and profit sharing rates in effect as enacted. The Company 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.

The Company’s deferred income tax assets include certain future tax benefits. The Company 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.

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 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. The Company reviews, on an annual basis, unless otherwise deemed necessary, the reclamation obligation at each mine site in accordance with ASC guidance for reclamation obligations.

MINERA YANACOCHA S.R.L.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

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.

Comprehensive Income

In addition to Net income (loss), Comprehensive income (loss) includes all changes in equity during a period, such as foreign currency, translation adjustments, cumulative unrecognized changes in fair value of marketable securities available-for-sale or other investments, except those resulting from investments by and distributions to owners.

Reclassifications

Certain reclassifications between amounts reported in the income statement of prior years have been reclassified according the 2013 presentation.

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 the 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. 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, 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 Company’s fiscal year beginning January 1, 2014. The Company is still evaluating the impact of the updated guidance on the consolidated financial position, results of operations or cash flows.

The Maqui Maqui tax stability agreement expired on January 1, 2012; consequently subsequent to that date it is subjected to the tax regime currently in force at year-end.

The Company, with the assistance of legal advisors, determines the taxable income based on its understanding 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 and by certain differences between U.S. and International Financial Reporting Standards (IFRSs) beginning 2013 (Peruvian generally accepted accounting principles, up through 2012).

For the years ended December 31, 2013, 2012 and 2011 the income tax rate was 30% except for the La Quinua mine for which a 29% income tax rate applied.

Other Mining Taxes

| a) | Law N° 29788, Mining Royalties

On September 28, 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.

According to this legislation, the mining royalty is payable quarterly, based on sales and operating profit determined in accordance with Peruvian generally accepted accounting principles (changed to IFRS in 2013). The royalty amount due is 1% of sales. 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 2013, 2012 and 2011, $7,134, $5,102 and $1,146, respectively, were included in Costs applicable to sales based on 1% of revenue and $6,132, $2,359 and $132 were included in Income and mining tax expense based on an average of 1.81%, 3.46% and 3.97% of operating profit, respectively.

| b) | Law N° 29789, Special Mining Tax

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 Peruvian generally accepted accounting principles (changed to IFRS in 2013). The rate varies depending on the level of operating profit. During 2013, 2012 and 2011; $11,693, $6,900 and $1,300, respectively, were included in Income and mining tax expense due to the IEM based on average of 3.45%, 3.13% and 3.69% of operating profit, respectively.

| c) | Law N° 29790, Special Mining Charge

The Special Mining Charge (“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 Peruvian generally accepted accounting principles (changed to IFRS in 2013). The rate varies depending on the level of operating profit margin. The GEM applied to operations at Cerro Yanacocha and La Quinua in 2013, 2012 and the fourth quarter of 2011. This change resulted in $12,547, $68,644 and $19,661, respectively, of additional Income and mining tax expense based on average of 3.23%, 6.55% and 5.95% of operating profit, respectively.

Unrecognized Tax Benefits

At December 31, 2013 and 2012, the Company had $1,198 of total gross unrecognized tax benefits that, if recognized, would impact the Company’s effective income tax rate. The Company’s continuing practice is to recognize interest and/or penalties related to unrecognized tax benefits as part of its income tax expense. The Company files income tax returns with Peruvian taxing authorities and is no longer subject to income tax audits by taxing authorities for years before 2008.

| 7. | FAIR VALUE ACCOUNTING

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 (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

| Level1 | Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

| Level2 | Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

| Level3 | Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

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 and provisional priced metal sales contracts.

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 net trade receivable from provisional silver, gold, carbon fines and copper concentrate sales is valued using quoted market prices based on the forward the COMEX Silver Index, the London Bullion Market Association P.M. fix (“London P.M. fix”) (gold), and the London Metal Exchange (“LME”) (copper), and, as such is classified within Level 1 of the fair value hierarchy.

| 14. | WORKERS’ PROFIT PARTICIPATION

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.

In 2013, 2012 and 2011, the current expense portion of workers’ profit participation amounted to $52,966, $80,748 and $79,057, respectively, of which the majority was included in Costs applicable to sales and in minor portion assigned to Conga project.

Peruvian law limits payments of annual profit sharing per employee to eighteen months salary but continues to base total profit sharing on 8% of taxable income, notwithstanding the per employee limitation. Supreme Decree N°009-98-TR, published on August 6, 1998, provides that the excess of total profit sharing for the year over aggregate profit sharing payable to all employees be paid to the Fondo Nacional de Capacitación Laboral y de Promoción del Empleo (“FONDOEMPLEO”). Law 28464 published in January 2005, which modified article 3 of Law Decree 892, provides that the excess of total profit sharing for the year over aggregate profit sharing payable to all employees be applied to training of employees and construction of public facilities. Supreme Decree N°002-2005-TR, published in May 6, 2005, establishes a limit of 2,200 UIT (inflation measurement unit, of S/.3,700 new Peruvian sol per unit at December 31, 2013) in the contributions to FONDOEMPLEO indicating that the difference goes to the Regional Government.

| 16. | RECLAMATION AND REMEDIATION

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.

Income and Mining Tax Contingencies

Income and mining tax contingencies are provided for under ASC guidance (see Notes 2 and 6).

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 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 are in exploration.

| · | The Company must pay 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 Los Tapados S.A. 3% of the quarterly net sales proceeds of mineral extracted from the transferred and leased concessions. 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.

Legal proceedings

Choropampa (mercury spill)

In June 2000, a transport contractor of Yanacocha spilled approximately 151 kilograms of elemental mercury near the town of Choropampa, Peru, which is located 53 miles (85 kilometers) southwest of the Yanacocha mine. Elemental mercury is not used in Yanacocha’s operations but is a by-product of gold mining and was sold to a Lima firm for use in medical instruments and industrial applications. A comprehensive health and environmental remediation program was undertaken by Yanacocha in response to the incident. In August 2000, Yanacocha paid under protest a fine of 1,740,000 Peruvian soles (approximately $500,000) to the Peruvian government. Yanacocha has entered into settlement agreements with a number of individuals impacted by the incident. As compensation for the disruption and inconvenience caused by the incident, Yanacocha entered into agreements with and provided a variety of public works in the three communities impacted by this incident. Yanacocha cannot predict the likelihood of additional expenditures related to this matter.

Additional lawsuits relating to the Choropampa incident were filed against Yanacocha in the local courts of Cajamarca, Peru, in May 2002 by over 900 Peruvian citizens. A significant number of the plaintiffs in these lawsuits entered into settlement agreements with Yanacocha prior to filing such claims. In April 2008, the Peruvian Supreme Court upheld the validity of these settlement agreements, which the Company expects to result in the dismissal of all claims brought by previously settled plaintiffs. Yanacocha has also entered into settlement agreements with approximately 350 additional plaintiffs. The claims asserted by approximately 200 plaintiffs remain. In 2011, Yanacocha was served with 23 complaints alleging grounds to nullify the settlements entered between Yanacocha and the plaintiffs. Yanacocha has answered the complaints and will continue to vigorously defend its position. The Company cannot reasonably estimate the ultimate loss relating to such claims.

Since December 2010 to date, 23 new claims involving 29 plaintiffs were received by Yanacocha. In these claim, plaintiffs are requesting the Judge to (i) declare void the compensation agreement signed with Yanacocha and to (ii) award them with new compensation amounts. Two of these new claims involving two plaintiffs were dismissed as they did not comply with formal requirements.

In 19 of these cases, the initial presiding judge admitted a motion to dismiss based on prescription of the actions and dismissing the processes. Plaintiffs appealed this decision, and Superior Court confirmed it in 18 cases. In 8 of these cases, plaintiffs have challenged this decision in front of the Supreme Court, but to date one of them has already been dismissed.

In one of the claims, a different presiding judge accepted the Company’s motion to dismiss the claim regarding a new award but the Supreme Court has dismissed the matters and confirmed statute of limitations declared by Cajamarca Superior Court.

Baños del Inca

In September 2006, the Municipality of Baños del Inca issued a declaration designating an area that includes the Carachugo Expansion and San José Projects as reserved and protected areas. Based on previous experience and actions taken by the Constitutional Tribunal (Peru Court of Last instance for Constitutional issues) in respect of Cerro Quilish in which it was ruled that such declaration did not affect the Company’s mining rights, the Company believes that Baños del Inca’s declaration, should not impact the Company’s legal rights to exploit these concessions.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

In March 2008, the company filed an Action for Constitutional Relief (Amparo) against the Municipality of Baños del Inca seeking that the referred ordinance be declared inapplicable. The Court of first instance of Lima rejected the claim lodged by the Municipality of Baños del Inca regarding the jurisdiction of such court to hear this case. On March 14, 2011 the Court of first instance of Lima served the ruling it had issued declaring the complaint inadmissible. The judgment was appealed by Yanacocha. By a resolution served on August 15, 2011, the first Civil Courtroom of the Superior Court of Lima declared void the judgment of first instance, ordering the Judge to issue a new ruling. On September 7, 2012 Yanacocha requested the Civil Courtroom to issue a judgment due to its constitutional rights being seriously threatened by the Municipality of Baños del Inca. The action is pending a new judgment to be issued by the Court of first instance with no judgment issued to-date.

San Pablo

In February 2007 the Municipality of San Pablo issued an Ordinance declaring Las Lagunas and Pozo Seco, where the company holds concession rights, as reserved and protected areas. According to past experience and actions taken by the Constitutional Court with regard to Cerro Quilish, where it was ruled that such declaration did not affect the company's mining rights, the Company believes that in this case, the declaration issued by the Municipality of San Pablo should not impact the legal rights it has to exploit these concessions. The company filed an Action for Constitutional Relief (Amparo) challenging the Ordinance on the grounds that, under Peruvian law, local governments are not empowered to create such areas, denying the rights granted by the Peruvian mining concessions. The Court of first instance rejected the complaint on grounds of form; then, the corresponding appeal was lodged.

On November 19, 2008 the second Civil Courtroom of the Superior Court of Lima confirmed the first instance ruling rejecting the action for relief, which led to the filing of an extraordinary appeal with the Constitutional Court.

By a ruling dated December 10, 2010 the Constitutional Court revoked the resolution issued by the second Civil Courtroom of the Superior Court of Lima and ordered that the complaint be admitted for processing.

By resolution served on March 25, 2011, the Court of First Instance admitted the complaint for processing and that it is served to the Provincial Municipality of San Pablo. The Municipality of San Pablo answered the complaint asserting the expiration of the statute of limitations of the action for relief. Yanacocha has requested the rejection of the expiration of the statute of limitations asserted on the grounds that the complaint for constitutional relief was timely filed.

On October 31, 2012 the defendant presented new evidence. By resolution served on December 10, 2012, the Courts resolved to confirm the Resolution N°26 which declared unfunded the exception of prescription of the case. The Court ruling on the statute of limitations is pending until March 2014.

Conga Project

Regional Ordinance No. 036-2011-GR.CAJ-CR dated December 5, 2011 issued by the Regional Government of Cajamarca (hereinafter the Regional Ordinance) was published in the Official Gazette "El Peruano" on December 28, 2011.

F-119

MINERA YANACOCHA S.R.L.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

The Regional Ordinance, among other things, declares the unworkability of the implementation of the Conga Project in the headwaters of the basin where the following lakes are found: el Perol (District of Sorochuco); Azul and Cortada (District of Huasmín); Mamacocha (District of Bambamarca) and all those located in the area of influence of the Conga Project on the grounds of the existence of technical - legal inconsistencies in the Environmental Impact Assessment approved by Directorial Resolution No.351 - 2010 - MEM/AAM, dated October 27, 2010, and also on the grounds that it contravenes constitutional norms and international treaties. Furthermore, it declared the invalidity of any legal rule that contravenes the referred Regional Ordinance.

There is Constitutional Court jurisprudence establishing that large scale mining projects fall under the exclusive jurisdiction of the Executive Power, not of the Regional Governments or Municipalities. The Attorney General filed an unconstitutionality action with the Constitutional Court seeking that this regional ordinance be declared unconstitutional and void. The complaint has already been admitted for processing by the Constitutional Court.

On April 17, 2012, Constitutional Court granted the action brought by Attorney General and declared unconstitutional the Regional Ordinance. This final ruling was published in the Official Gazette "El Peruano" on April 27, 2012.

At the same time, Yanacocha initiated an action for constitutional relief to declare the inapplicability of Regional Ordinance No. 036-2011-GR.CAJ-CR. As the ruling by Constitutional Court declared unconstitutional the Regional Ordinance, this actions is no longer needed.

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 on 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.

Clínica International, Adecco, SGC Security

Employees belonging to three contractors (Clinica International, Adecco, SCG Seguridad) have filed legal actions during 2008 claiming to be included in Minera Yanacocha's payroll. These workers claim that for all practical effects they are employees of the Company and therefore are entitled to all the rights attached thereto, arguing that they receive direct orders from Yanacocha and that most of the infrastructure and equipment used in the performance of their duties is also provided by the Company. These proceedings involve a total of 97 workers. The cases are detailed as follows:

MINERA YANACOCHA S.R.L.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands unless otherwise stated)

Regarding the Adecco employees, the complaint includes 77 plaintiffs. This complaint was declared groundless in the first instance and confirmed by the Civil Courtroom. Thus, the plaintiffs filed an appeal for reversal. As of February 2013, the records were forwarded to the Standing Constitutional and Social Courtroom of the Supreme Court of Justice of the Republic, but the complaint was not accepted. Also during this time, some of the plaintiffs desisted from the claim. As of the date of the filing, this complaint is finished, as no plaintiffs are remaining in the process.

Regarding the Clinica International employees, the complaint includes 14 plaintiffs. On January 2014, three cases were dismissed by first instance. The remaining 11 are in process until March 2014.

In the case of SGC Security workers, the complaint includes 6 plaintiffs. The issuance of judgment in the first instance is pending, since the previous judgment was declared null by the Civil Courtroom. On January 31, 2014, the claim was dismissed by the court.

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 below table sets out the outstanding signed commitments at year end by financial institution. In general, these letters of guarantee are renewed annually with the last extension being through January 18, 2015.

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 Copper & Gold Inc.), which comprise the statements of financial position as of December 31, 2013 and 2012, and the related statements of comprehensive income, statements of changes in equity and statements of cash flows for each of the three years ended December 31, 2013, 2012 and 2011 and a summary of significant accounting policies and other explanatory notes. 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, 2013 and 2012, and the results of operations and its cash flows for each of the three years ended December 31, 2013, 2012 and 2011, in conformity 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 27 to the Financial Statements).

Sociedad Minera Cerro Verde S.A.A.

Notes to the financial statements

As of December 31, 2013, 2012 and 2011

| 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-McMoRan Corporation (“FMC”), a wholly owned subsidiary of Freeport-McMoRan Copper & Gold Inc. (“Freeport”), owns 53.56% of the voting shares of the Company. Additionally, 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 Asiento Minero Cerro Verde S/N Uchumayo – Arequipa. The ore deposits are located southwest of the city of 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

The Company is engaged in a large-scale expansion of Cerro Verde´s production unit. The US$4.6 billion project will expand the processing capacity from 120,000 metric tons per day of ore to 360,000 metric tons per day, targeting incremental annual production of approximately 600 million pounds of copper and 15 million of molybdenum beginning in 2016. In December 2012, the Company received approval of the Environmental Impact Study from the Peruvian Ministry of Energy and Mines. As of December 31, 2013, the Company has invested US$1.5 billion in this project.

| (c) | Financial statements approval -

The financial statements for the year ended December 31, 2013 were approved by Company´s Management on April 30, 2014 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 2014.

F-130

Notes to the financial statements (continued)

| 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 (“US”) dollars and include the years ended December 31, 2013, 2012 and 2011. 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. All exchange differences are taken to the statement of comprehensive income.

The Company uses exchange rates published by the Superintendent of Banks, Insurance and AFP. As of December 31, 2013, the published exchange rates were S/.2.794 for US$1 for buying and S/.2.796 for US$1 for selling (S/.2.549 for US$1 and S/.2.551 for US$1, as of December 31, 2012, respectively). These rates have been applied to the appropriate asset and liability accounts. As of December 31, 2013 and 2012, the Company did not maintain significant assets or liabilities in foreign currency.

| (b) | Financial assets -

The Company determines the classification of its financial assets at initial recognition in accordance with IAS 39, “Financial Instruments: Recognition and Measurement”.

Financial assets are recognized initially at fair value plus the direct costs attributable to the transaction. The Company’s financial assets include cash and cash equivalents, accounts receivable and embedded derivatives.

Cash and cash equivalents -

Cash and cash equivalents are financial assets that may be liquidated immediately, such as bank accounts, and other liquid investments with original maturities of three months or less.

Receivables -

The Company’s receivables include trade accounts receivables to related parties and third parties and other accounts receivable. These receivables are stated at their transaction value, net of an allowance for doubtful accounts.

F-131

Notes to the financial statements (continued)

Receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. After initial measurement, 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.

| (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.

F-132

Notes to the financial statements (continued)

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.

| (d) | Property, plant and equipment -

The 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.

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 10 and 30
Machinery and equipment | Between 3 and 25
Transportation units | 7
Furniture and fixtures | 7
Other equipment | Between 3 and 25

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 the property, 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.

The asset’s residual values, useful lives and methods of depreciation are reviewed, at each reporting period and adjusted prospectively, if appropriate.

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.

F-133

Notes to the financial statements (continued)

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.

| (e) | Exploration, development and stripping costs –

Exploration costs -

Mineral exploration costs, as well as drilling and other costs incurred for the purpose of obtain 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 judgement, 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.

| (f) | Stripping costs -

As part of its mining operations, the Company incurs in stripping cost during development and production phases of its operations. Stripping costs incurred in the development phase of a mine, before production commences (development stripping) are capitalized as development costs and subsequently amortized using the UOP method over the life of the mine. The capitalization of stripping cost stops when the mine production commences.

Stripping costs incurred during the production phase 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:

| - | It is probable that the future economic benefit;

| - | The Company can identify the component of the ore body for which access has been improved; and

| - | The costs related to the stripping activity associated with that component can be measured reliably.

To identify components in a mine site, the Company works in coordination with the mine planning area.

The stripping activity asset is initially measured at cost, which is the accumulation of costs directly incurred to perform the stripping activity and is disclose as part of the property, plant and equipment.

The stripping activity asset is subsequently depreciated using the units of production method over the life of the identified component of the ore body that became more accessible as a result of the stripping activity. The stripping activity asset is then carried at cost less depreciation and any impairment losses.

See impacts of adoption of IFRIC 20 Stripping Cost in Production Phase of a Surface Mine in note 2.3.

F-134

Notes to the financial statements (continued)

| (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.

| (h) | 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.

F-135

Notes to the financial statements (continued)

Mine closure provision -

The Company records a mine closure provision 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 mine closure provision annually and makes adjustments to estimates and assumptions, including future costs and discount rates, as applicable. Changes in the fair value of the mine closure provision 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.

| (i) | 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.

Sales of copper cathodes and concentrates –

Local 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.

F-136

Notes to the financial statements (continued)

| (j) | Income taxes, deferred taxes and other taxes -

Income taxes -

Income tax assets and liabilities are measured at the amounts expected to be paid to or recovered from the tax authorities. The tax rates and tax laws that are applied to compute the amounts are those that are enacted or substantially enacted at the end of the year. The Company calculates the provision for income tax in accordance with the Peruvian tax legislation in force. The income tax rate in Peru was 30% as of December 31, 2013 and 2012.

Deferred taxes -

The deferred income tax is presented using the liability method for differences between the tax basis of assets and liabilities and their book values for financial reporting purposes. Deferred tax liabilities are recognized for all temporary differences. Deferred tax assets are recorded for all deductible temporary differences when there is a probability that there could be future taxable earnings against which the deductible temporary differences could be applied.

The book value of the deferred tax asset is reviewed at the end of each period and reduced to an amount that is more likely than not to be realized against taxable earnings. Deferred tax assets that are not recognized are reassessed at each period and are recognized when it is more likely than not that future taxable earnings will allow for the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at tax rates that are expected to be applicable during the year when the assets are realized or the liabilities are liquidated, based on the tax rates (and tax laws) that have been enacted at the end of the period. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset tax assets against tax liabilities and the deferred tax is related to the same entity and the same tax authority.

Mining Taxes -

On September 29, 2011, Law 29788 (which amended Law 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 will be subject to a revised royalty and a special mining tax. The Company operates under a stability agreement and therefore was not subject to the revised royalty and special mining tax until its stability agreement expires 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 15 (d).

F-137

Notes to the financial statements (continued)

| - | 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 the Law No. 29788.

Mining Royalties and Special Mining Tax are in the scope of IAS 12 and are considered income tax.

| (k) | 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 Found 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.

| (l) | 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, 2013 and 2012, 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.

| (m) | Fair value -

The Company measures the 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.

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.

F-138

Notes to the financial statements (continued)

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.

| 2.3. | Changes in accounting policies and disclosures

The Company applied for the first time, certain standards and amendments effective from January 1, 2013. The only standard requiring modification of previously issued financial statements is IFRIC 20, Stripping Cost in the Production Phase of a Surface Mine. In addition, the application of IFRS 13, Fair Value Measurement, resulted in additional disclosures in the financial statements.

Several other standards and amendments became effective during the year 2013 which did not have a significant impact on the financial statements or financial statements disclosures of the Company.

The nature and impact of each new rule applicable to the Company is described below:

IFRIC 20-Stripping Costs in the Production Phase of a Surface Mine

IFRIC 20 became effective January 1, 2013. Prior to the adoption of IFRIC 20, , the Company recorded stripping incurred during the mine´s production stage as a variable production cost and included them in the cost of inventory produced during the period when such stripping costs were incurred. As a result of the adoption of IFRIC 20, the stripping cost of production that is necessary to produce the inventory continues to be recorded as a cost of production; however, the overburden waste removal stripping costs incurred that improve access to further quantities of material to be mined in future periods is capitalized and amortized based on proved and probable reserves of each ore body (component) identified in the open pit. See further explanation of the application of IFRIC 20 in Note 2.2 (f).

Impact on the statement of cash flows

The effect on the statement of cash flows was a decrease to cash flows from operating activities of US$52.6 million as a higher amount of stripping costs was allocated directly to inventory during the year and an decrease to cash flows used in investing activities of US$52.6 million as a lower amount was capitalized to the stripping activity asset during the year.

The Company decided not to recognize the effect of IFRIC 20 adoption in its financial statement for the period ended December 31, 2011 since the effect is not significant to total asset, equity, net income and cash flow.

IFRS 13 Fair Value Measurement

IFRS 13 establishes a single source of guidance under IFRS for all fair value measurements. IFRS 13 does not change when an entity is required to use fair value but rather provides guidance on how to measure fair value under IFRS when fair value is required or permitted. IFRS 13 defines fair value as an exit price.

F-141

Notes to the financial statements (continued)

Application of IFRS 13 has not materially impacted the fair value measurements of the Company. Additional disclosures where required, are provided in the individual notes relating to the assets and liabilities whose fair values were determined.

| 3. | Accounting estimates, judgments and assumptions –

The preparation of the financial statements according to IFRS requires that Management make judgments, estimates and assumptions that affect the amounts of the assets and liabilities reported, the disclosure of contingent assets and liabilities as of December 31, 2013 and 2012, and the reported amounts of revenues and expenses for the three years ended December 31, 2013, 2012 and 2011.

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 only be resolved when one or more future events do or do not occur. Determining contingencies inherently involves the exercise of judgment and calculation of the estimated results of future events.

| (b) | Stripping cost - (note 2.2 (f) and 2.3) –

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.

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., tons) of waste to be stripped and ore to be mined in each of these components.

| (c) | Functional currency-

The functional currency for the Company and its parent entity, is the currency of the primary economic environment in which the entity operates. The Company has determined the functional currency is the US dollar. Determination of functional currency may involve certain judgments to determine the primary economic environment and the parent entity reconsiders the functional currency of its entities if there is a change in events and conditions which determined the primary economic environment.

| 3.2 | Estimates and assumptions -

| (a) | 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.

F-142

Notes to the financial statements (continued)

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.

| (b) | Estimates of ore 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.

| (c) | Units-of-production (“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.

F-143

Notes to the financial statements (continued)

| (d) | Asset impairment –

The Company has determined that the Cerro Verde operation consists of one cash generating unit, considering the operation as a whole. Therefore, the Cerro Verde operation is evaluated annually in order to determine if there are any 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.

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.

| (e) | Mine closure provision -

The Company 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, interest rates and inflation rates. As discussed in note 2.2(h), 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 asset retirement cost (ARC) in accordance with IAS 16, “Property, Plant and Equipment”. If any change in the estimate results in an increase to the 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”.

| 4. | Standard issue but not effective

The standard that is issued, but not yet effective, up to the date of issuance of the Company’s financial statements is disclosed below:

IFRS 9 Financial Instruments: Classification and Measurement –

IFRS (2009) presents new requirements for the classification and measure of financial assets. IFRS 9 (2010) presents new requirements related to financial liabilities. IFRS 9 (2013) presents new requirements for hedge accounting that alligned it with risk management; also those requirements establish an approach based on hedge accounting principles addressing inconsistencies and weaknesses in the hedge accounting model defined in IAS 39. At present, IASB has a project to modify some classification and measurement requirements from IFRS 9 and include new requirements to deal with the impairment of financial assets. The adoption of this new IFRS 9 is not specified, yet, and will be determined when the phases in discussion are clear. However, the anticipated adoption is permitted.

| (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. Management plans to use them 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.

Notes to the financial statements (continued)

| (c) | Peruvian Tax Authorities (SUNAT) have the right to examine, and, if necessary, amend the income tax as determined by the Company during the last four years, calculated from the year following that in which the tax returns are filed. The income tax returns for the years 2009 to 2012 and the value added tax returns for the period from January 2009 to December 2012 are open to examination by The Tax Authorities. The income tax returns for the years 2002 to 2008 have been reviewed by SUNAT, and the Company has interposed claims and/or appeals.

In addition the income tax returns for years 2009 and 2010 are being reviewed.

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.

| (d) | Mining taxes -

As described in note 2.2(j), Law 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, 2013 and 2012, the Company recorded a tax provision of US$63,202,000 and US$82,467,000, respectively, related to the special mining burden. In addition, the Company has also recognized an income and expense deferred tax amounting to US$24,000 and US$3,851,000 during the years 2013 and 2012, respectively.

| (e) | On June 23, 2004, Law No.28258 - Mining Royalty Law was approved, and requires the holder of a mining concession to pay a royalty in return for the exploitation of metallic and non metallic minerals, which is calculated using rates from one to three percent of the value of concentrate or its equivalent according to the international price of the commodity published by the Ministry of Energy and Mines.

Based on the 1998 stability agreement described above in letter (a), the payment of the mining royalties was not applicable to the Company since this contribution was created after the Company signed the stability contract with the Peruvian government.

F-154

Notes to the financial statements (continued)

The Peruvian tax authority (SUNAT) has assessed mining royalties on materials processed by the Company’s concentrator, which commenced operations in late 2006. Such assessments cover the period from October 2006 to December 2007, as well as years 2008 and 2009. SUNAT has issued resolutions rejecting the claims of the Company. The Company has appealed such decisions before the Tax Court. On July 23, 2013, SUNAT notified the final decision of the Tax Court confirming the assessments for the periods October to December 2006, and for the years 2007 and 2008. By means of the decision of the Tax Court, the administrative stage for the appeal of these proceedings ends.

In September 2013, Cerro Verde filed judiciary appeals to Judiciary Court (Civil Court of the Superior Court of Arequipa) suing SUNAT, the Ministry of Energy and Mines and Tax Court for requiring the Company to pay mining royalties during the term of the stability agreement in force until 31 December 2013. The Company believes that the Stability Agreement entered into with the Peruvian government in 1998 (which was in force from January 1, 1999, to December 31, 2013 (See note 15(a)) guarantees that all minerals extracted from their production unit are included in the stabilized tax and administrative regime, which does not include the obligation to pay the Mining Royalty.

On October 1, 2013, SUNAT issued a payment order by 492 million of nuevos soles (US$ 176 million based on current exchange rates, including interest and penalties of US$104 million). As permitted by law, the Company requested and as has been granted an installment payment program that defers payment for six months and thereafter satisfies the amount via 66 equal monthly payments. In July 2013, a claim on SUNAT´s assessment for 2009 was rejected, but no final decision has been issued by the Tax Court for that year.

In Management’s and legal advisors’ opinion, the Company has sound legal grounds; consequently, it believes any payments will be recoverable.

| 19. | Commitments and contingencies

| (a) | Environmental matters -

The Company’s mining and 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 N°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 N°203-2009 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.

F-158

Notes to the financial statements (continued)

The table below presents the changes in the provision for remediation and mine closure:

|  | US$(000) |
Balance as of January 1, 2012 |  |  | 7,061 |
Accretion expense |  |  | 239 |
Changes in the estimates |  |  | 72,512 |
Balance as of December 31, 2012 |  |  | 79,812 |
Accretion expense |  |  | 4,609 |
Changes in the estimates |  |  | (36,445 | )
Other adjustments |  |  | 503 |
Balance as of December 31, 2013 |  |  | 48,479 |

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, 2013, the future value of the provision for closure of mining units and environmental liabilities was US$115,654,000, which was discounted using the annual risk-free rate of 5.71%, resulting in an updated liability of US$ 48,479,000 (as of December 31, 2012, the future value of the provision for closure of mining units and environmental liabilities was US$145,881,000 and was discounted using an annual risk-free rate of 4.65%, which resulted in an updated liability for US$79,812,000). The Company considers that this liability is sufficient to meet the current environmental protection laws approved by the MEM.

Up today the Company has issued letters of credit to Ministry of Energy and Mines amounting to US$14,851,000 to secure mine closure plans for its mining unit.

| (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 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.

F-159

Notes to the financial statements (continued)

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.

In August 2013, the Ministry of Housing, Construction and Sanitation approved the environmental and social impact assessment of the waste water treatment plant.

This waste water treatment plant allows the viability of the Company’s Production Unit expansion project, benefiting the population of Arequipa as it will help to decontaminate the waters of the Rio Chili, and improve the health, the quality of the agricultural products, the tourism and the environment in general.

Notes to the financial statements (continued)

| 23. | 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 prices of copper and molybdenum have a significant impact on the Company’s operating results. The price of copper and molybdenum 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 six 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.

The table below summarizes the effect on profit before income tax and workers’ profit sharing caused by changes in the copper and molybdenum 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 2013 positive scenario uses prices between US$/pound 3.66 to 3.68 (US$/pound 3.95 to US$/pound 3.96 in the year 2012 and US$/pound 3.78 to US$/pound 3.80 in the year 2011); whereas the negative scenario uses prices between US$/pound 2.99 to 3.01 (US$/pound 3.23 to US$/pound 3.24 in the year 2012 and US$/pound 3.09 to US$/pound 3.11 in the year 2011).

December 31, 2011 |  |  |  |
Increase in copper and molybdenum international quotes |  |  | 51,573 |
Decrease in copper and molybdenum international quotes |  |  | (51,573 | )

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, remuneration and other accounts payable in currencies other than the US dollar, mainly Nuevos Soles. The Company mitigates its exposure to exchange-rate risk by carrying out almost all of its transactions in its functional currency and Management maintains only small amounts in Nuevos Soles to cover its needs in this currency (i.e., taxes and remuneration).

During 2013, the Company has recorded net loss net from exchange difference of US$1,858,000 (net gain of US$3,149,000 during the year 2012 and net gains of US$1,924,000 during the year 2011), from the translation of balances in Nuevos Soles to the US dollars.

| (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 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, 2013 and 2012.

| 24. | Hierarchy and fair value of financial instruments

Hierarchy:

As of December 31, 2013 and 2012 the only financial asset carried at fair value is the embedded derivative, which is generated by the sale of mineral and measured at fair value based on copper prices. The value of this embedded derivative at December 31, 2013 was US$18,408,000 (US$11,569,000 as of December 31, 2012). This asset is categorized within Level 2 of the hierarchy.

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.

F-166

Notes to the financial statements (continued)

The fair value of embedded derivatives is determined using valuation techniques using information directly observable in the market (forward prices of metals).

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.

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, 2013 and 2012.

Mineral for milling |  |  | 3,879,706 |  |  |  | 3,992,384 |  |  |  | 0.37 |  |  |  | 0.38 |

Copper production in thousands of recoverable pounds for the years ended December 31, 2013 and 2012 was as follows:

|  | 2013 |  |  | 2012 |
Cathodes |  |  | 104,314 |  |  |  | 118,703 |

Average LME price per metric ton of copper for the years ended December 31, 2013 and 2012, was as follows:

|  | 2013 |  |  | 2012 |
|  | US$/MT |  |  | US$/MT |
Copper |  |  | 7,322 |  |  |  | 7,950 |

| 26. | 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 27 and are principally related to the items discussed in the following paragraphs:

Income tax

Under IFRS, current and deferred tax assets and liabilities are measured at the tax rate applicable to undistributed profits and thus the income tax consequences of dividends are recognized when a liability to pay the dividend is recognized.

Under U.S. GAAP, with respect to the income tax consequences of undistributed earnings, the Company recognizes deferred tax liabilities at the applicable tax rate based on its tax planning strategies, and not necessarily when they are distributed. Accordingly, the Company had recorded deferred income tax liabilities related to certain undistributed earnings, according to ASC 740 “Accounting for Income Taxes”.

In 2012, due to revised expected timing of dividend distributions (that were deferred beyond year 2013 and accordingly no subject to Income Tax), the Company decided to reverse the deferred income tax liability under US GAAP.

Notes to the financial statements (continued)

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.

| 28. | New U.S. GAAP Accounting Pronouncements

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

Recently Issued Accounting Pronouncements -

Presentation of an Unrecognized Tax Benefit

In July 2013, 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 Company’s fiscal year beginning January 1, 2014. The Company is still evaluating the impact of the updated guidance on the financial position, results of operations or cash flows.
