The Company now deals from strength. Going forward, it will enjoy the advantages of scale that are critical for continuing, long-term success in our industry.
Dear Shareholders,
2005 was a transformative year for our Company. We brought three new mines into production, met or exceeded our financial and other targets in almost every area of our business, and launched a successful bid to acquire Placer Dome Inc.
As a result, Barrick now holds a preeminent position within the gold mining industry. We are one of the very few with the strength, breadth and scale to handle the challenges facing our sector, and seize its equally significant opportunities.
The Company now deals from strength. Going forward, it will enjoy the advantages of scale that are critical for continuing, long-term success in our industry. We will discuss the transaction and its value to shareholders at greater length later in this letter, but first want to take this opportunity to welcome our new shareholders. The entire Barrick team respects the skills of Placer Dome employees, and looks forward to working with them in this great new venture. Together, we are building a much stronger enterprise that will create value for shareholders, employees, and the communities in which we live and work.
While the acquisition was certainly the biggest news of 2005, it does not exist in isolation. It was made possible by the success of the comprehensive business plan that we initiated in 2003. We have been methodically implementing it ever since, with a single overriding objective: to create value for shareholders. Indeed, Barrick shares outperformed the Philadelphia Gold and Silver Sector Index from 2003 until we launched our bid for Placer Dome. We expect that they will provide superior value once again, as we deliver on the strategic rationale of the acquisition.
In following our business plan, we reorganized Barrick into the decentralized regional business

units that now serve our expanding global activities so well, and we made a Company-wide commitment to leadership, urgent action, accountability, and results. We developed cost-mitigation strategies to address industry-wide pressures, and we laid out an aggressive schedule for bringing into production six new mines between 2005 and 2009.
Three of those new mines came into production in 2005, and a fourth project, Cowal, continued to advance. Collectively, they came within 5% of our overall $1.2 billion development budget, discussed in the 2004 Letter to Shareholders. The new mines helped drive rising production and profitability during the year, just as we anticipated in last year’s annual report.
We posted excellent financial results in 2005, and our production and cash costs were in line with our original guidance, in a difficult cost environment. We further strengthened our management team during the year, and we maintained our strong commitment to responsible mining through our health and safety, environmental, and community development programs.
With this strong year behind us, we are confident that we will complete the integration of Placer Dome quickly and effectively, and begin realizing the synergies and potential of this powerful new company.
Gold Price, Industry Issues... and the Barrick Strategy
We are now shaping Barrick to ensure we remain an industry leader. Gold prices and the outlook for gold are both strong, yet the industry continues to face very significant challenges. We will continue to address those challenges and improve our competitive position, while reaping gold-price benefits.
Gold had an excellent year in 2005, with highs that had not been seen since 1981. The rally, which began in 2001 and was originally driven by a declining US dollar, is now widely considered to be based on fundamentals. Global investment demand more than doubled in 2005; the combined gold holdings of all gold ETFs (Exchange Traded Funds) rose by 115%; and some central banks have suggested that they may add to reserves.
Against this backdrop of growing demand, supply is flat. The industry’s overall lack of investment in exploration and development, between 1998 and 2003, is now being felt. There are few new major discoveries, and mine production rose by a modest 1% in 2005.
All of this is bullish for the gold price, but it comes at a time of challenges for the industry. Attractive deposits are in increasingly remote locations; permitting and review is more rigorous and time-consuming; capital and operating costs are higher; social responsibility standards, rightly, continue to rise; and the expertise needed to produce gold is at a greater premium than ever before.
Few companies will be able to benefit from today’s opportunities, because few have the track record and strength to handle this array of challenges. Barrick is one of the few.
We have consistently maintained our investment in exploration and development, and have the new mines and pipeline of development projects to show for it. We have the expertise, financial strength and corporate good citizenship to meet the technical, regulatory, environmental, and community requirements now associated with producing gold — profitably, and responsibly. All this places us in a very strong competitive position.
Delivering Value in 2005
In 2005, net income increased 62% to $401 million and cash flow from operations rose 43% to $726 million.
Profits increased, as production rose from 1.1 million ounces in the first quarter to 1.65 million ounces by year-end. The new generation of mines drove these increases, and can be expected to

continue with their contribution in 2006, the first full year of production for all three.
Barrick was the only senior producer to be in line with its original production and cash cost guidance for 2005. We produced 5.46 million ounces of gold and our total cash cost per ounce for the year was $227.
We have an unrelenting focus on cost-mitigation. Our currency and commodity hedging programs help us avoid cost pressures in these areas, or greatly reduce their impact.
We also continue to strengthen our continuous improvement and supply chain management programs.
The industry’s tire shortage is a good example of the success of our approach. We are increasing the life of our existing tires by as much as 25% and we are using our purchasing power to ensure a more dependable tire supply.
We are finding other innovative ways to manage costs. For example, we commissioned our own electric power facility at Goldstrike, the Western 102 Power Plant, in early November — the first business in Nevada to take advantage of the right to leave the regulated grid.
As a result of these and other initiatives, Barrick remained the lowest-cost senior producer in 2005.
Production increased each quarter throughout the year, to meet our expectations for 2005 and post a 10% increase over 2004.
During 2005, three development projects achieved start-up and became producing mines:

n |  | Tulawaka (Tanzania) in Q1, a small but high-return operation, which builds upon our presence in Tanzania;
n |  | Lagunas Norte (Peru) in Q2, with proven and probable gold reserves of 8.3 million ounces; and
n |  | Veladero (Argentina) in Q4, with proven and probable reserves of 12.6 million ounces of gold, marking the start of production from the highly prospective Frontera District on the Chile/Argentina border.

Our strong financial results for 2005 reflect three key factors: growth in production, due to the contribution made by our three new mines; the rising gold price; and our focus on keeping cash costs low so as to expand our operating margins.
The Way Ahead
The Placer Dome acquisition will deliver value to shareholders from the assets, people and projects of the combined companies. Placer Dome’s key assets lie in close proximity to Barrick’s, and our collective projects comprise an unrivalled pipeline for growth. The fit is excellent.
We expect the acquisition to be accretive to Net Asset Value, reserves, resources and production per share, and to allow us to capture $200 million worth of synergies a year, beginning in 2007. Yet the ultimate importance of this transaction, and its value to shareholders, goes beyond those numbers. The power of this combination allows us to deal from strength, in an environment where only the best and the strongest will thrive. We did not acquire Placer Dome to become the largest gold company in the world. We acquired it to ensure that our shareholders and employees will thrive.
Today Barrick can run operations, build and finance projects, manage the supply chain, attract and retain personnel, and in every area execute our work better than before, because of this new depth of talent and resources. We have the scale and strength to address the challenges facing the industry, and capitalize on its opportunities as well.

2005 was truly a landmark year for Barrick. It was the culmination of years of planning and execution, and financial discipline, which positioned us for the great step forward — the acquisition of Placer Dome.
Delivering Value: the Outlook for 2006
A core priority for 2006 is the effective and timely integration of Placer Dome. We began to implement the integration plan the day after we acquired control of the company. We are approaching this objective with the same rigor and urgency that characterize all key corporate initiatives, such as our development projects. We will focus all our energies on building Barrick, capturing the synergies, and delivering value.
In 2006, we will benefit from the first full year of production for each of the three mines brought on-stream in 2005, and from our new Cowal Mine as well. It will be the seventh mine we have brought into production since 1996. Seven mines in ten years — an unequalled track record. We are also making progress with the East Archimedes project in Nevada, where production is expected to begin in 2007. With the approval of Pascua-Lama by the Chilean authorities, the next milestone for the project is approval in Argentina. With construction expected to begin later this year, Pascua-Lama is targeted to commence production in 2009.
With the acquisition of Placer Dome, we are now applying our depth of exploration and development expertise to the entire combined pipeline of projects, which will drive growth and create value for the Company well into the future.
In summary, 2005 was truly a landmark year for Barrick. It was the culmination of years of planning and execution, and financial discipline, which positioned us for the great step forward — the acquisition of Placer Dome. We wish here to pay tribute to our employees, for all this is truly their achievement.
We also wish to pay tribute to Angus MacNaughton, a valued colleague who joined the Company’s Board of Directors in 1986, was Vice-Chairman during a critical growth period, and is now retiring. He has provided wise counsel over the years and will be missed. At the same time, we welcome three former Placer Dome directors to our own Board: Donald J. Carty, John W. Crow and Robert M. Franklin, and another independent director, Brett Harvey. Their knowledge and support will benefit our Company and its combined shareholders and dedicated employees.
On a more personal note, the two of us have been close business associates and colleagues since bringing Barrick into the gold mining business in 1983. From that standing start, we have nurtured Barrick to its current position of strength, scale and industry leadership. Building on fundamental business principles, we will continue to focus on performance for the benefit of all Barrick’s stakeholders.

Barrick and Placer Dome
The Combined Company: Value for Shareholders
Barrick’s overriding objective is to create shareholder value — value over time, even as the times change and new opportunities and challenges arise. This objective shapes our corporate culture and organization, our financial approach, the priorities for our operations, our consistent investment in exploration, and our strategy for acquisitions.
We have been assessing various acquisition possibilities, weighing them against our value-creation criteria for the environment in which gold companies must now operate. Placer Dome met those criteria, and we realized the company would be an excellent fit with our own assets, people and projects.
We announced our offer in late October 2005. In late December, we negotiated a final price that allowed us to complete the deal on a friendly basis with the support of Placer Dome’s Board of Directors, management and employees. With this acquisition, we have acquired 12 operating mines and three projects, exploration properties all over the world, and a rich pool of talented people. We expect the transaction to be accretive to earnings and cash flow on a per-share basis in 2007 and beyond.
The combined Company is an industry leader, operating with the strength and scale that the times demand. We go forward in this environment with:

n |  | significantly increased reserves, resources and production;
n |  | low-cost production relative to our peer group;
n |  | clusters of operating assets in close proximity to each other, on the world’s most prospective gold belts;
n |  | an unrivalled pipeline of projects, to which we can apply our development expertise;
n |  | a world-class team with proven exploration success and project-development expertise; and
n |  | the strongest financial position in the industry.

The quality and geographic fit of the assets, combined with the skills of our people and our decentralized business platform, give us confidence that we will capture an anticipated $200 million in annual synergies, as of 2007.
Value from Projects and Project-Development Expertise
Barrick has the industry’s best suite of projects and properties through 2009 and beyond — and the skills and financial strength to realize these value-creation opportunities to the full.

6 n Barrick and Placer Dome

#####

The combined assets will mesh in time, as well as geographic proximity, to assure continuing growth. The three acquired projects — Cortez Hills (Nevada), Donlin Creek (Alaska), and Pueblo Viejo (Dominican Republic) — overlap with our existing ones, to extend the pipeline and provide lucrative growth opportunities for Barrick into the future.
All these projects will be managed by one highly skilled and experienced team, in a Company that has brought seven new mines into production in the last ten years. No other gold mining company has this track record of speed, efficiency and success, backed by the industry’s strongest balance sheet.
Experience has taught us how to handle the challenges associated with designing, permitting, financing and building projects in today’s demanding environment. All these skills are now focused on creating value for shareholders from our larger, longer pipeline of quality projects and the opportunities that it presents.
Value from Exploration
Exploration is one of Barrick’s core strengths. We have a track record of consistent exploration, and considerable success. Lagunas Norte, for example, now a producing mine in Peru, was the largest greenfield discovery in the industry in a decade. The result of our exploration program has been a strong, geographically diversified package of quality land positions, which create value through additional reserves, resources and, ultimately, production.
Now we are integrating a complementary suite of exploration properties, focused on the same multi-million-ounce gold districts in Nevada, Frontera (Chile/Argentina), Tanzania and Australia. The combined assets give us a significant position on the most prospective ground in all four regions.
Barrick in Nevada:

n |  | interests in six operating mines;
n |  | interests in two development projects, East Archimedes and Cortez Hills;
n |  | over 34 million ounces of proven and probable gold reserves and almost 10 million ounces of measured and indicated gold resources; and
n |  | strong land positions on the region’s three major trends — Carlin, Getchell, and Battle Mountain-Eureka.

Barrick and Placer Dome n 7

#####

Barrick in the Frontera District:

n |  | one operating mine (Veladero) and one development project (Pascua-Lama);
n |  | over 30 million ounces of proven and probable gold reserves and 2 million ounces of measured and indicated gold resources;
n |  | a 3,000-square-kilometer position on this highly prospective district straddling the Chile/Argentina border; and
n |  | a first-class exploration team, which is familiar with the area and combines Barrick and Placer Dome expertise in high-sulphidation and porphyry deposits.

Barrick in Tanzania:

n |  | three mines and two projects;
n |  | nearly 18 million ounces of proven and probable gold reserves and over 3 million ounces of measured and indicated gold resources;
n |  | an extensive suite of quality exploration properties in the highly prospective Lake Victoria Gold Belt; and
n |  | Tanzania’s best team of exploration geologists.

Barrick in Australia:

n |  | eight mines, six of them clustered in Western Australia;
n |  | over 14 million ounces of proven and probable gold reserves and 8 million ounces of measured and indicated gold resources;

n |  | commanding land positions in the Kalgoorlie, Laverton, Agnew and southern Yandal gold belts; and
n |  | a strong, well-established team of exploration personnel, positioned to deliver value from all parts of Australasia.

We are combining our skills and our best practices in exploration systems and technology, as well. We are using this strength to prioritize and streamline projects already in the exploration pipeline in order to add ounces more effectively around existing operations and development projects, and to enhance our success in finding new ounces in emerging regions.
We are also combining R&D expertise, which will lead to advances we can apply in underground and open-pit mining, mineral processing, and environmental management.
Value from Financial Strength
Barrick has the financial strength to continually invest in exploration, develop new mines, and run its operations both profitably and responsibly.
With the strongest balance sheet in the industry and access to over $2 billion in capital resources through existing cash and credit resources, we are able to develop all our projects on the scale and with the timelines they require — and to do so without equity dilution.

Barrick has the financial strength to continually invest in exploration, develop new mines, and run its operations both profitably and responsibly.
Value from Synergies
We see the opportunities for $200 million in annual synergies, and we have the business platform and the management capability to capture that value in full as of 2007.
These synergies are anticipated in five key areas: Operations, Exploration, Procurement, General and Administrative (G&A), and Finance and Tax. In Operations, we will optimize and share mining and processing infrastructure in Nevada, Australia and Tanzania; reduce energy costs and inventory levels through joint infrastructure; and implement combined best practices at all locations.
In Exploration, we will consolidate our land positions on the most prospective belts and prioritize our pipeline of exploration projects. In Procurement, we expect to generate significant savings from our improved purchasing power as deployed by our worldwide supply management group. The savings in G&A will come from shared business practices, and the elimination of duplication in offices and overheads in all regions. With Finance and Tax, we will realize jurisdictional tax synergies and enjoy both debt optimization and a lower overall cost of capital.
Finally, in addition to the areas factored into the $200-million calculation above, we can expect capital synergies. Through the sequential development of our project pipeline, we will be able to transfer development teams, equipment and a comprehensive knowledge base from one project to the next. This pipeline also allows for in-house management of engineering, procurement and contract management (“EPCM”) contracts.
The Placer Dome acquisition strengthens Barrick’s Nevada footprint with three new mines (above, Cortez) and a development project.
Barrick has the management capability, enriched by our experience with the Homestake acquisition, to optimize the value of our combined assets, people and projects. We also have the appropriate organizational structure: an existing decentralized platform of Regional Business Units, which allows us to integrate the assets and welcome the people, quickly and well.
Value Now
The increased strength of this powerful combination is already being felt. Throughout the integration period, there has been a parallel emphasis on “business as usual.” Our teams have continued to focus on their exploration, development and production targets, steadily generating value for the Company and its shareholders.
With the completion of the integration process — to be largely accomplished by mid-2006 — our people will fully concentrate on the opportunities we now have the strength and scale to seize.
In addressing our overriding corporate objective — to create shareholder value — Barrick goes forward with greater financial strength, greater depth of talent, and a pre-eminent suite of operating mines, projects, and exploration properties.

Responsible Mining
Avalanche preparedness (here, Veladero, Argentina) is just one of the range of safety measures at high-altitude operations.
Responsible mining has always been an intrinsic part of this Company’s business model, and is a key element of our vision to be the world’s best gold company. It involves sharing the benefits of mining with the countries and communities where we work, establishing open dialogue and partnership in those communities, and earning the trust of all those with whom we interact by dealing fairly with them. Our performance record travels before us, creating opportunities to generate shareholder value and sustainable development.
Safety and Health
At Barrick, we are committed to performing every job in a safe and healthy manner, in order to achieve our safety vision of “every person going home safe and healthy every day.” The safety and health of all workers is the top priority at all Barrick operations. Key to the success of Barrick’s safety and health commitment is leadership at every level of the organization. Courageous Leadership, a Company-wide safety program launched in 2004, is an example of this commitment. It draws on safety-related best practices, establishes clear roles and responsibilities for all personnel, and holds individuals accountable for their practices. By year-end 2005, Barrick’s entire management and supervisory group had received training and trainers were beginning to work with hourly employees and contractors.
Employee Development
Barrick believes in enabling employees to develop to their full potential. We respect and value each of our employees and observe the fundamental tenets of human rights, safety, and non-discrimination in the workplace. We fairly compensate our employees for their contributions, provide meaningful performance feedback to them, and offer them professional development and training opportunities. Employee involvement in issues affecting the workplace helps improve safety and work conditions, as well as our efficiency and our business overall.
Community Development
It is a fundamental tenet of Barrick’s business strategy to contribute to the sustainable economic and social development of the communities in which we work and live. We share the benefits associated with our mining operations in many different ways, including local hiring, local and regional buying, community infrastructural investment, small business development, and improved education and health services.
Local stakeholder consultation is the cornerstone of Barrick’s responsible mining practice. Early in the development of a community/sustainability program, we conduct a socioeconomic assessment, which provides a useful benchmark for our community development efforts. Thereafter, we maintain a dialogue with community leaders and other

stakeholders, which serves to prioritize these efforts, monitor performance, and adjust the focus of initiatives as appropriate. During 2005, for example, our community/sustainability program in Peru included financial and in-kind support for schools, health initiatives, small business, agricultural irrigation systems, and water, septic and electrification systems —all in partnership with the people, institutions and local authorities of the communities concerned.
Partnerships
Wherever possible, Barrick draws on the skills and expertise of other organizations to complement our own community development programs. In 2005, we continued our relationships with three international non-governmental organizations (NGOs): CARE, Habitat for Humanity, and World Vision. We have also developed strong relationships with Indigenous Peoples, including partnerships with the Tahltan First Nations in British Columbia and the Wiradjuri Condobolin Registered Native Title Claimants Group in Australia. This type of multifaceted collaboration helps ensure that our support and programs are well-targeted and complementary to existing initiatives.
United Nations Global Compact
In 2005, Barrick joined the UN Global Compact, an initiative to promote corporate citizenship by directly involving business in addressing some of the major social and environmental challenges that arise from increasing globalization. The ten principles of the Global Compact are based on internationally recognized norms and conventions in four critical areas: human rights, labor standards, the environment, and anti-corruption. By endorsing the Global Compact, Barrick has made a commitment to incorporate the ten principles into its culture, strategy, and day-to-day operations. It has also committed to report on the key practical actions it takes to support the ten Global Compact principles and their expected outcomes.
Environment
Barrick has a responsibility to protect, reclaim, and where possible enhance the environment on the sites where we operate. We practice conscientious environmental stewardship and diligently apply proven management controls to achieve this goal. In 2005, Barrick became one of the first signatories to the International Cyanide Management Code for the Gold Mining Industry — a voluntary code developed by a multi-stakeholder committee under the auspices of the United Nations Environment Program and the International Council on Metals and the Environment. Signatories commit to follow the principles and implement the standards of practice of the Code, to have their relevant operations undergo a third-party audit and to make public the audit results.
Charitable Giving
Barrick’s Heart of Gold Fund is another way we contribute to the communities where we work and live. Barrick’s policy is to give one percent of annual pre-tax income to charitable causes. Recipients range from community outreach programs to hospitals and schools, environmental programs, art and cultural events and major research institutions.

Financial Strategy
“Barrick will continue to improve its financial profile and maintain a conservative financial philosophy as it moves forward with its capital investment program.”
Moody’s Investor’s Service (January 2006)
Barrick continues its long tradition of operating from a strong, prudent financial base. In 2005, the Company:

n |  | brought three new mines on-stream, and advanced a fourth to near-completion, all without issuing any equity to finance them;
n |  | managed cost pressures successfully;
n |  | remained the lowest cash-cost producer of the senior gold mining companies; and
n |  | structured an innovative share and cash transaction for the acquisition of Placer Dome, which included the sale of certain assets to Goldcorp, in order to maximize the resulting synergies.

Financing
In 2004, we stated that we would execute the industry’s most aggressive growth plan without the need to issue additional equity. In 2005 we achieved that objective, bringing three new mines into production and significantly advancing a fourth, which is scheduled to enter production in the first quarter of 2006.
In April, the Company’s wholly-owned subsidiary, Minera Barrick Misquichilca S.A., issued $50 million of bonds in the Peruvian capital markets. The issue, which was at a 28-basis-point discount to Sovereign debt, was one of the highest ever ratings in that country. The money was used to partially fund construction of the new Lagunas Norte Mine in Peru, thereby making Peruvian investors our partners in a project of great importance to their country.
Cost Control/Cost Management
2005 was another year of challenging cost pressures for the entire mining sector. Many gold producers revised their guidance significantly during the year to reflect the negative impact of these pressures on both production and cash-cost metrics. Barrick, by contrast, did not revise guidance and remained the lowest cash-cost senior gold producer for the year.
This success is due to the range of highly complementary cost-management programs in place. These include currency hedging to mitigate the impact of rising currencies in countries where we operate; hedging of consumables such as fuel costs; supply chain management; and continuous improvement. The collaboration exists across corporate functions and regions, and through the extended enterprise to outside suppliers as well. Individual initiatives reinforce each other and, in combination, create leverage for the Company as a whole.
For example, industry costs in 2005 were affected by stronger currencies in many of the countries where gold is mined. Barrick was less affected than many other companies because 75% of our 2005 costs were denominated in US dollars and we largely eliminated currency exposure on the remaining 25% through our currency hedging program. This allowed us to benefit from higher US-dollar gold prices and thus mitigate the impact on our mining costs of currency appreciation elsewhere.

12 n Financial Strategy

#####

Continuous improvement (CI) and supply chain management (SCM) are two more important examples of the way interrelated strategies provide cost-mitigation leverage. The CI program helps reduce Company costs by reducing the rate at which materials of all kinds are consumed. Program initiatives focus on improving operational efficiencies, and also on embedding a culture of CI so that improvements are sustained, and later enhanced whenever possible.
While CI addresses consumption of materials, SCM focuses on their cost — total cost, from purchase through the item’s life cycle to eventual salvage or safe disposal. The SCM group not only coordinates Company purchase contracts to gain the leverage of scale, it also ensures that each spend category operates at its most cost-effective level.
We will continue to deploy our full range of cost-containment strategies as part of our overall focus on maintaining and, where possible, reducing our costs in equipment, currencies, oil, interest rates and other areas that affect industry profit margins.
Gold Sales Contracts
During the year, we reduced our fixed-price gold sales contracts position by 1.0 million ounces.
The Company remains committed to its policy of reducing existing gold sales contracts. With the acquisition of Placer Dome, we will inherit additional contracts, but will continue to reduce the total number of contracts we hold, increasing Barrick’s leverage to the gold price.
We have already begun to reduce these contracts. All of Placer Dome’s outstanding call options as well as some of their forward contracts have been eliminated, representing a reduction of approximately 1.5 million ounces. By mid-February 2006, the combined gold sales commitments totaled 18.5 million ounces. Of this, a total of 9.5 million ounces of the hedge position has been allocated to the Pueblo Viejo and Pascua-Lama development projects. The remaining 9.0 million ounces of Corporate gold sales commitments represent 8% of total reserves excluding ounces allocated to development projects.
A more detailed discussion of our corporate gold sales contracts can be found in the Management’s Discussion and Analysis (“MD&A”) section on page 61.
Placer Dome Acquisition
On October 31, 2005, we announced a bid for all outstanding shares of Placer Dome for a combination of Barrick shares and cash. We increased the bid on December 22 and received the unanimous support of the Board of Directors of Placer Dome.
The strategic rationale and opportunities presented by this transaction are outlined earlier in this report. We will issue additional shares in order to complete the transaction, and in exchange we will receive significant value in the form of Placer Dome operations, assets and development projects. The cash necessary to complete the transaction is to be recouped through our agreement to sell certain assets of Placer Dome to Goldcorp, resulting in no new debt for the combined Company. Barrick remains the most highly rated gold company in the world, with the industry’s only A-rated balance sheet (as rated by Standard & Poor’s).
In the future as in the past, Barrick will maintain a sound and prudent financial foundation. On this solid base, the Company will run existing operations, fund exploration programs, and advance development projects.

Barrick Overview
Building Mines, Delivering Value
It was a year of solid, profitable achievement, capped by the bid for Placer Dome. In 2005, Barrick:

n |  | increased gold production by 10%;
n |  | held total cash costs in line with guidance;
n |  | brought three new mines into production; and
n |  | launched the successful bid to acquire Placer Dome.

Barrick produced 5.46 million ounces of gold in 2005, at total cash costs of $227 per ounce. This strong production derives from both our existing mines, such as Goldstrike (which produced over 2 million ounces), and the contribution from the Company’s new mines, in particular Lagunas Norte in Peru.
Average total cash costs of $227 per ounce were in line with our original guidance for the year. This achievement, in a year of extreme cost pressure, is a tribute to our cost-mitigation initiatives and supply chain management efforts, which include close attention to operational detail and the procurement of consumables and equipment on the best possible terms, worldwide.
Three new mines entered production in 2005: Tulawaka (Tanzania), Lagunas Norte (Peru) and Veladero (Argentina). We also made excellent progress with our development projects and exploration targets. Cowal (Australia), East Archimedes (Nevada) and Pascua-Lama (Chile/Argentina) remained on schedule for their anticipated start-ups in first quarter 2006, 2007, and 2009, respectively. Exploration targets at both Buzwagi (Tanzania) and South Arturo (Nevada) yielded encouraging results.
In April, Barrick made Russia/Central Asia the Company’s newest Regional Business Unit and opened an office there, laying the groundwork for opportunities in this highly prospective part of the world.
Finally, on December 22, 2005, Barrick reached agreement with Placer Dome for a friendly transaction, an achievement that positioned Barrick for its next phase of value creation. Combining the talent and physical assets of these two companies will create an industry powerhouse beginning in 2006.
Exploration
Barrick has a motivated, discovery-driven team of over 150 geoscientists exploring for gold in over 16 countries around the world. Reserve development and replacement of production is a major priority for all sites. The Company consistently funds its exploration programs throughout all gold cycles, and has a proven track record of finding ounces at both greenfield and brownfield projects.
Exploration is focused on highly gold-endowed districts where Barrick controls large land positions, primarily the Goldstrike and Pipeline districts in Nevada, the Frontera District in Chile/Argentina, and the Lake Victoria District in Tanzania. In addition, the Company is exploring earlier-stage projects in Australia, Canada and West Africa, as well as evaluating exploration opportunities in emerging districts around the world.
Three key factors drive the Company’s exploration success: the motivation and technical excellence of its exploration team; the policy of consistently investing
Barrick initiatives result in longer life for existing tires (here, Lagunas Norte, Peru) and a more dependable supply of new ones.

in exploration; and the robust and balanced pipeline of exploration projects. The Company’s disciplined exploration strategy maximizes the chance of near-term discovery by putting the best people on the best projects and advancing the best projects more quickly up the exploration pipeline.
Outlook for 2006
Based on our preliminary view of the Placer Dome assets combined with those of Barrick, we expect to produce 8.6 to 8.9 million ounces of gold at total cash costs of between $275 and $290 per ounce in 2006.
We also expect to produce approximately 350 million pounds of copper at total cash costs of approximately $0.75 per pound before the impact of one-time purchase accounting adjustments relating to the Placer Dome acquisition that will add $0.35 to the costs per pound reported in 2006. This is due to the revaluation of opening inventory at the date of acquisition from historic cost to fair value.
2006 Company Performance Plan
As always, our focus is to deliver shareholder value. We will do this by building the Company and delivering profitable business growth. To succeed in this objective, we will focus our energies in the following five key areas:
Integrate Placer Dome

n |  | integrate all corporate functions, establish the combined organization
n |  | position Barrick to fully capture synergies as of 2007
n |  | strengthen the management team

Deliver Results

n |  | meet or outperform budgets for gold production and total cash costs
n |  | further reduce corporate gold sales contracts
n |  | maintain our position as the lowest cash-cost senior gold producer

Reinforce Social Responsibility

n |  | demonstrate leadership in health and safety
n |  | enhance community development programs
n |  | maintain high standards of environmental performance

Strengthen the Organization

n |  | further develop leadership capacity, Company-wide
n |  | leverage our size and scale to enhance our competitive position

Grow the Business

n |  | pursue new exploration opportunities
n |  | advance the pipeline of projects

The Regional Platform
Barrick’s Regional Business Units
The Company will integrate its assets and build its future on Barrick’s platform of Regional Business Units, implemented in 2004. Barrick reorganized itself into this decentralized structure in order to manage its business more effectively by moving responsibility and decision-making capabilities closer to the operations which they affect.
This model not only provides the necessary decentralization — it strengthens, and depends on, the corporate culture of leadership at every level. Each regional team, led by its own president, has two key responsibilities: to optimize its current assets and to grow the business in that region. The Toronto corporate office continues to set policies and procedures, provide strategic guidance, and direct the Company as a whole. Each region is responsible for all aspects of its business, including strategy/sustainability, and for the management of all aspects of mining operations, including exploration, development/construction, production and closure.
The Company currently has four units: North America, South America, Australia/ Africa (which will be divided into two distinct units in 2006), and Russia/Central Asia. In the first three, which are affected by the integration process now underway, most of the core assets are clustered in close proximity to each other — a factor that will greatly facilitate the speed, efficiency and synergies of the integration.
The next few sections provide a brief overview of the activities that took place in each of the Company’s business regions in 2005. A more detailed operational review can be found in the Management’s Discussion and Analysis (“MD&A”) that begins on page 29.

Regional Overview
In Nevada, the driving engine of the region, significant steps were taken during the year to contain costs. Goldstrike produced 2 million ounces of gold at total cash costs of $255 per ounce. The Company also commissioned its own natural-gas-fired electric power generating facility, which is expected to reduce cash costs and improve the reliability of electricity supply over the life of the Goldstrike facilities. The 115-megawatt Western 102 plant, which began operation in early December, had a construction capital cost of $96 million, and was completed on schedule and on budget. It is one example of Barrick’s innovative, effective approach to cost containment. The Company will use the experience gained designing and building this project to explore opportunities to reduce electricity costs at other operations.
A pit expansion was approved at our Round Mountain joint venture with Kinross Gold, which will extend mine life from 2010 to 2015. Barrick’s share (50%) of proven and probable gold reserves at Round Mountain increased from 1.5 to 2.3 million ounces after depletion.
Work at the East Archimedes development project continued to proceed smoothly. During the year required permits were received, the mining fleet arrived on site, and pre-strip activities began. This project — an open-pit, heap-leach operation — is on schedule to enter production in mid-2007 and has 1.0 million ounces of proven and probable gold reserves.

Exploration
In Nevada, exploration was carried out on 35 targets, with most of the activity focused on the Goldstrike Property, and on Rossi, Dee and REN, all on the Carlin Trend. One of the exploration highlights of 2005 was the discovery of the South Arturo zone on the Dee Property where Barrick has a 60% interest. Twenty-eight holes were drilled to test this new target and all holes intersected oxide mineralization. Preliminary metallurgical results are favorable. Follow-up drilling will resume early in 2006 and will include in-fill and extension holes. Deep drilling beneath the North Post resource at Goldstrike intersected a potentially significant new zone. The underground drill program continued in January. In addition, drill programs at Dee and Rossi were successful in upgrading the reserve/resource at Storm, and production is scheduled for late 2006. The Placer Dome acquisition will greatly expand exploration opportunities in Nevada, with new properties on the Battle Mountain-Eureka and the Getchell trends.
2006 Opportunities
North America is Barrick’s original region of operation and is still the largest, in terms of both production and reserves. Even as our other regions grow their contributions to the Company’s bottom line, North America maintains its position as a Barrick powerhouse. In 2006, we will capitalize on the region’s strengths in order to seize its opportunities, including those being presented through the acquisition of Placer Dome.
The Western 102 Power Plant, commissioned in early December 2005, is designed to lower energy costs at Goldstrike.
The Placer Dome assets will strengthen our Nevada footprint in particular, and extend our substantial presence on its three great trends: Carlin, Getchell, and Battle Mountain-Eureka. Three of our four new operating mines are located there (Cortez, Turquoise Ridge and Bald Mountain), as well as one new development project (Cortez Hills). The close proximity of these assets to our existing operations will result in a powerful combination of human and physical resources. Highly skilled people are involved from both Barrick and Placer Dome, who already know the terrain and, to a large degree, know each other as well.

Regional Overview
In 2005, the earlier exploration and mine-building in this region began to deliver significant growth and value. South America added two new mines, one each in Peru and Argentina, and advanced the sizeable Pascua-Lama development project. The region expanded its community and environmental programs during the year as well, further cementing local trust and respect that in turn facilitate our mining objectives.
Lagunas Norte, in the Alto Chicama District in Peru, began operations in the second quarter. The mine illustrates two core strengths of the Company: its ability to find significant new deposits and its ability to develop them. When discovered in 2002, it was the largest grassroots find in a decade. Within three years, it was an operating mine — completed within its $340-million budget and ahead of schedule.
The new Veladero mine, in Argentina, began operations in the fourth quarter. This start-up marked our first production from the highly prospective Frontera District straddling the Chile/Argentina border, which is also home to our Pascua-Lama development project. Barrick’s land position in this district has over 30 million ounces of proven and probable gold reserves, with approximately 880 million ounces of contained silver.

The Pascua-Lama development project is eight kilometers to the north-west of Veladero, and will benefit from experience gained during the construction phase at Veladero. In early 2006, the Chilean environmental authorities approved the modifications to the project, and the next milestone is expected to be approval of the environmental impact study in Argentina. If permits are obtained for Pascua-Lama in mid-2006, as expected, construction will begin later in the year, with production expected in 2009.
Exploration
Exploration activity in 2005 was focused on the Frontera District in Chile and Argentina and on the Alto Chicama District in Peru. Frontera is a core district for exploration, with field work resuming mid-2004. Work in 2005 included an integrated program to explore this 3,000-square-kilometer land package that is now under one owner. Drill programs were carried out on three targets close to Pascua/Veladero. Ground surveys delineated and prioritized new targets for drill testing in the first half of 2006 and regional work will continue to define targets for detailed follow-up. Drilling will also be carried out on targets north and south of Pascua/Veladero, which were delineated during the regional field work.
Exploration tests further potential in the Frontera District, which already has over 30 million ounces of proven and probable gold reserves.
Lagunas Norte, Peru, illustrates Barrick’s ability to find significant new deposits and develop them quickly. In 2002, it was the largest grassroots discovery in a decade; in 2005 (within budget, ahead of schedule), it became an operating mine.

Infrastructure at Veladero, Argentina (left to right): the truck shop, the covered ore stockpile, the secondary crusher and the loadout bin, where trucks collect crushed ore to haul to the valley-fill leach facility. 2006 will be the mine’s first full year of production.
In Peru, targets remain to be tested in the Alto Chicama District, where the regional field work will be completed in 2006.
2006 Opportunities
In 2006, the region will make a significantly greater contribution to the Company’s financial results, from both existing assets and those gained through the Placer Dome acquisition. For the same reasons, the region has enhanced growth potential.
2006 will be the first full year of operation for Lagunas Norte and Veladero. They are both long- life, low-cost mines, located in prospective gold districts (Alto Chicama and Frontera, respectively). They will contribute significant production for many years to come, and provide an excellent platform for future growth in the region.
Through the acquisition of Placer Dome, the Zaldívar open-pit copper mine in Chile has been added to the region’s assets, along with hundreds of skilled, experienced people. Zaldívar is a large, long-life, low-cost copper mine in the north of Chile. It will generate substantial cash flow at current copper prices.

Regional Overview
Tulawaka, which commenced production in first quarter 2005, is a small but high-return mine that adds to our presence in Tanzania. Buzwagi, an advanced-stage exploration target, now has a proven and probable reserve of 2.4 million ounces of gold.
In Australia, the Cowal development project progressed well and is widely credited for establishing new benchmarks in environmental management and permitting standards. The two-year construction phase was almost complete by year-end 2005, and Cowal remained on schedule for its first gold production in late first quarter 2006. Construction costs are anticipated to be about 10% above the prior $305 million guidance due to inflationary cost pressures in Australia. However, we expect the project to begin selling production at a much higher gold price than we anticipated when we made the construction cost estimate.
Exploration
Tanzania is a significant focus for exploration. Barrick is the major landholder in the highly prospective Lake Victoria Gold Belt and with the Placer acquisition will have the most prospective land package in the country. At Buzwagi, the 2005 drill program was successful in upgrading and expanding the existing resource. Engineering studies were carried out and the pre-feasibility study completed.

When Cowal (Australia) enters production, expected Q1 2006, it will be Barrick’s fourth new mine on-stream within 12 months.
Barrick carried out a drill program to test the Nyanzaga Property, located north-east of Bulyanhulu. A zone of shallow mineralization has been defined over a strike length of 700 meters and remains open along strike and at depth. Preliminary metallurgy shows good recoveries for both the primary and oxide mineralization. An infill and extension drill program will be carried out in 2006.
In Australia, Barrick carried out field programs on six properties. The exploration is predominantly focused on targets in Western Australia, a more mature district that still holds good potential for new discoveries. Barrick’s exploration programs will be augmented with the addition of prospective Placer tenements.
2006 Opportunities
In the first quarter of 2006, Cowal is scheduled to enter production. The mine has proven and probable gold reserves of 2.5 million ounces and measured and indicated gold resources of 2.0 million ounces. The minimum mine life is expected to be approximately ten years. Once in full production, Cowal is expected to be a significant contributor to gold production and cash flow generated from operations in this region.
At Buzwagi, the permitting process with Tanzanian authorities is underway, and a feasibility study has commenced in order to support a production decision later in 2006.
In 2005, the Company entered into a joint-venture agreement with Falconbridge Limited whereby they acquired a 50% interest in the Kabanga project for $15 million cash and a funding commitment. Falconbridge will now be the operator of the project and has begun a $50 million exploration and infill drilling program to update the resource model and bring the project toward feasibility. In addition to the $50 million exploration program, Falconbridge will fund the next $95 million of any project development expenditures for the project.
The acquisition of Placer Dome adds seven producing mines to the existing six in the region and two new countries, Papua New Guinea and South Africa. As in other regions, most of these assets are close to existing Barrick operations.

Highlights
50% interest acquired in the Taseevskoye and Sredne Golgotaiskoye gold deposits

n |  | Russia/Central Asia established as the Company’s newest region;
n |  | Ownership in Highland Gold increased to 20%;
n |  | Drilling program continued to expand the size of the Federova palladium property; and
n |  | Exploration program in Russia expanded by acquiring new license areas in three regions.

Russia/Central Asia has a long and rich history in gold mining, and excellent geological potential for the discovery of new deposits that meet our criteria for quality and scale. The region also has a significant talent pool of well-trained mining professionals, graduating more university students in relevant disciplines each year.
Barrick has long recognized the potential of this area, as well as the need to proceed in a methodical and prudent manner. We began our first exploration programs here in 1996, continuing to build our expertise and relationships, and to strengthen our involvement as opportunities warrant.
In 2005, we judged it timely to establish a more broadly-based presence. Our new regional business unit is built, deliberately, on a modest scale but it provides an excellent platform for assessing the range of ways we might grow our business in the region.
For example, in 2005 we increased our equity interest in Highland Gold to 20 percent. We have also obtained a 50% interest in the Taseevskoye and Sredne Golgotaiskoye gold deposits. Taseevskoye is a previously mined open pit and underground mine that is now being re-evaluated in light of the current strong gold price environment.
At the Federova palladium property in northwest Russia, a drilling program carried out in 2005 continued to expand the size of the deposit, with additional drilling planned for 2006. In addition, Barrick acquired three new exploration properties in Russia (Lyubov, Belaya Gora, and Maya-Inikan), and has planned field work for 2006.
We have stepped up our involvement in Russia/Central Asia because of the potential we see in this region. We are now better positioned than ever to realize the value of that potential going forward. We will continue to seek qualified partners and invest in selected growth and exploration opportunities.

Our Business
Core Business
We are currently one of the world’s largest gold companies in terms of market capitalization, annual gold production and gold reserves. In early 2006, we completed the acquisition of Placer Dome, which will result in a significant increase in the scale of our mining operations. Details of the acquisition can be found on page 41. Our operations in 2005 were concentrated in these regions: North America, Australia/Africa and South America. In 2006, we intend to divide the Australia/Africa region into two separate regions. Each region receives direction from the Corporate Office, but has responsibility for all aspects of its businesses including strategy/ sustainability and managing all aspects of mining operations including exploration, development/ construction, production and closure.
We generate revenue and cash flow from the production and sale of gold. We sell our gold production in the world market through three primary distribution channels: gold bullion is sold in the gold spot market, gold bullion is sold under gold sales contracts between ourselves and various third parties, or gold concentrate is sold to independent smelting companies.

Vision and Strategy
Our vision is to be the world’s best gold company by finding, developing and producing quality reserves in a profitable and socially responsible manner.
Our goal is to create value for our shareholders. We reinvest cash flow from our mines in exploration, development projects and other investments to work towards sustainable growth in gold production and cash flow. It can take a number of years for a project to move from the exploration stage through to mine construction and production. Our business strategy reflects this long lead time, but shorter-term priorities are also set for current areas of focus.

Capability to Deliver Results
Resources and processes provide us with the capability to execute our strategy and deliver results. The critical ones are:
Experienced Management Team and Skilled Workforce
We have an experienced management team that has a proven track record in the mining industry. Strong leadership and governance are critical to the successful implementation of our core strategy. We are focusing on leadership development for key members of executive-level and senior mine management.
A skilled workforce has a significant impact on the efficiency and effectiveness of our operations. The remote nature of many of our mine sites presents challenges in maintaining a skilled workforce. Competition for well-trained and skilled employees is high in our industry, so we are focusing on employee retention, recruiting skilled employees, and positive labor relations. We maintain training programs to develop the skills that certain employees need to fulfill their roles and responsibilities. Priorities for our Human Resources group include strengthening our workforce, developing employee leadership skills and succession planning. We are implementing Human Resource system solutions to enhance our ability to analyze and manage labor costs, productivity and other key statistics to help us effectively manage the impact our workforce has on our mining operations.
Environmental, Health and Safety
As part of our commitment to corporate responsibility, we focus on continuously improving health and safety programs, systems and resources to help control workplace hazards. Continuous monitoring and integration of health and safety into decision-making enables us to operate effectively, while also focusing on health and safety. In 2005, we continued to focus on enhancing leadership and personal commitment through the development of our health and safety risk management guidelines, which were successfully piloted at one of our mine sites; training for all levels of supervision and management through our “Courageous Safety Leadership” program; and the full implementation of processes at both corporate and regional locations that support governance and accountability measurements. Key areas of focus for 2006 will include safety leadership through training and health and safety risk management practices; designing and enhancing processes and programs to ensure safety requirements are met; and communicating a safety culture as part of Barrick’s core values.
We are subject to extensive laws and regulations governing the protection of the environment, endangered and protected species, waste disposal and worker safety. We seek to continuously implement operational improvements to enhance environmental performance. We have environmental groups at the corporate, regional business unit and operating site levels to support our environmental efforts. In 2005, we established an Environmental, Health, Safety and Sustainability Committee to establish policy direction for environmental performance. We became a signatory to the International Cyanide Management Code and committed to certification of all of our operations. In 2005, we also became a signatory to the United Nations (“UN”) Global Compact, which represents the world’s largest voluntary corporate citizenship initiative. Among its principles, the UN Global Compact encourages businesses to support a precautionary approach to environmental challenges, undertake initiatives to promote greater environmental responsibility, and encourage the development and diffusion of environmentally friendly technologies. To provide further guidance toward achieving our environmental objectives, we developed a new Environmental Management System Standard in 2005. Each year, we issue a Responsibility Report that outlines our environmental, health and safety and social responsibility performance for the year.

#####

Cost Control and Supply Sourcing
Successful cost control and supply sourcing depends upon our ability to obtain and maintain adequate quantities of equipment, consumables and supplies as required by our operations at competitive prices. Our Supply Chain group is focusing on improving long-term cost control and sourcing strategies, for major consumables and supplies used in our mining activities, through global commodity purchasing teams. It also facilitates knowledge sharing across our global business and implementation of best practices in procurement. We continue to develop strategies to help us analyze and source consumables and supplies at the lowest cost over the life of a mine, including where appropriate, long-term alliances with certain suppliers to ensure adequate supply is maintained.
Maintenance represents a significant component of operating costs at our mines and impacts the availability of plant and equipment. Our Global Maintenance team is working to reduce maintenance costs and increase equipment utilization through an internal maintenance community. Key areas of focus include setting business process standards for maintenance to optimize usage of mine equipment and enable cost-effective purchasing of mine equipment. They are implementing a global maintenance system, based on the principles of Total Production Maintenance, to facilitate the sharing of best practices across the Company and to track capital equipment statistics such as utilization, availability and useful lives.
Information Management and Technology
Our Information Management and Technology group provides focused and responsive support to enable us to meet our current business objectives and long-term strategy elements. It manages significant risks, such as information security; risks relating to the implementation of new applications; and the risk of failure of critical systems. We are implementing strategies to mitigate these risks, including monitoring operating procedures and the effectiveness of system controls to safeguard data, evaluating the effective use of technology and maintaining disaster recovery plans. Other areas of focus include working with other functional groups to reduce technology diversity by standardizing system solutions, and ongoing analysis of business needs and the potential benefits that can be gained from system solution enhancements.
Continuous Improvement
Our Continuous Improvement (“CI”) group is focused on instilling a continuous improvement culture across the Company to increase shareholder value by reducing costs, improving throughput/productivity, and improving quality and safety. Our CI group coordinates annual operational/business reviews to identify and prioritize improvement opportunities. The group also facilitates strategic planning sessions to develop our business strategy.
Internal Controls Over Financial Reporting and Disclosure
We maintain a system of internal controls over financial reporting designed to safeguard assets and ensure financial information is reliable. We undertake ongoing evaluations of the effectiveness of internal controls over financial reporting and implement control enhancements, where appropriate, to improve the effectiveness of controls. In 2005, we focused on the design, testing and assessment of the effectiveness of internal controls over financial reporting to enable us to meet the certification and attestation requirements of the Sarbanes-Oxley Act (“SOA”) for 2006. We presently file management certifications annually under Section 302 and Section 906 of the SOA, and expect to comply with the reporting requirements of Section 404 of the SOA as required by law.

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 33

#####

We also maintain a system of disclosure controls and procedures designed to ensure the reliability, completeness and timeliness of the information we disclose in this MD&A and other public disclosure documents. Disclosure controls and procedures are designed to ensure that information required to be disclosed by Barrick in reports filed with securities regulatory agencies is recorded, processed, summarized and reported on a timely basis, as required by law, and is accumulated and communicated to Barrick’s management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Key Economic Trends
In 2005, there has been a continuation of the trend of higher gold and silver prices which, while benefiting gold revenues and by-product credits, also leads to higher gold royalty expenses. A trend of inflationary pressure on the cost of labor, other commodities and consumables, such as oil, natural gas and propane, has caused upward pressure on production costs. We believe that other companies in the gold mining industry are experiencing similar trends. The Placer Dome acquisition will lead to a general increase in the magnitude of the effect of these economic factors on our business.
Gold, Silver and Copper Prices
Market gold prices have a significant impact on our revenue. Silver prices impact total cash costs per ounce1 of gold as silver sales are recorded as a by-product credit. These prices are subject to volatile price movements over short periods of time, and are affected by numerous industry and macroeconomic factors that are beyond our control.
Gold prices followed an upward trend in 2005, closing the year at $513 per ounce. This trend continued into 2006 with gold reaching a 25-year high of $572 per ounce in early February 2006. In contrast to 2004, the correlation between gold prices and the Euro has lessened, which suggests that exchange rates have become less important in determining gold prices. Other economic influences such as supply and demand, oil prices, trade deficits and US interest rates are important factors in explaining gold price movements. Demand for gold continues, with reports that certain central banks are considering buying gold to add to their reserves, and strong jewelry demand in China and India. The prospects for gold as an investment remain favorable, particularly in response to any global economic/political uncertainty. The past few years have seen a resurgence in gold as an investment vehicle, with more readily accessible gold investment opportunities (such as gold exchange traded funds — “ETFs”).
Over the last three years, our realized gold sales prices have tracked the rising market gold price. Periods when our average realized price was below average market prices were primarily caused by us voluntarily choosing to deliver into gold sales contracts at dates earlier than the final contractual delivery date and at prices lower than prevailing market prices to reduce outstanding gold sales contracts.

#####

Silver rallied along with gold at the end of 2005, despite continued news that attrition in the US photographic market would depress demand. Silver prices have had support from industrial consumers as technological advances continue to provide silver with new uses, as well as robust jewelry demand from India. The last three years have seen a decline in our silver production, as reserves at our Eskay Creek mine are depleted and the mine approaches the end of its life. After Pascua-Lama begins production, we expect that the quantities of silver we produce will increase significantly.
The acquisition of Placer Dome will lead to copper prices having a more significant effect on our results due to copper production from the Zaldivar copper mine and the Osborne gold and copper mine. In 2005, these mines combined produced 359 million pounds of copper. Copper prices rose 67% in 2005 as a result of supply reductions, smelter bottlenecks, and low global copper inventory levels, combined with ongoing high levels of copper demand. In early February 2006, copper prices reached a high of $2.33 per pound. In 2006, we purchased put options to protect revenue on approximately 300 million pounds of expected 2006 copper production. These options guarantee a minimum price of $2.00 per pound, while allowing us to fully participate in higher spot copper prices.

Currency Exchange Rates
Results of our mining operations in Australia and Canada, reported in US dollars, are affected by exchange rates between the Australian and Canadian dollars and the US dollar, because a portion of our annual expenditures are based in local currencies. Placer Dome has a mine located in South Africa that will cause us to also have economic exposure to the South African Rand in the future.
A weaker dollar would cause costs reported in US dollars to increase. The Canadian dollar outperformed most major currencies in 2005, including the US dollar, mainly due to sustained higher energy prices and global investor interest in resource assets. We expect the Canadian dollar to remain strong in 2006. The Australian dollar remains steady, mainly due to higher commodity prices, and the exchange rate with the US dollar was fairly stable in 2005. The Rand has shown increased stability against the US dollar in 2005 as compared to previous years, mainly due to increased liquidity and continued strong foreign direct investment in South Africa.

We have a currency hedge position as part of our strategy to control costs by mitigating the impact of volatility in the US dollar on Canadian and Australian dollar-based costs. Over the last three years, our currency hedge position has provided benefits to us in the form of hedge gains when contract exchange rates are compared to prevailing market exchange rates as follows: 2005 — $100 million; 2004 — $96 million; and 2003 — $58 million. These gains are reflected in our operating costs.
Our currency hedge position at the end of 2005 provides protection for our Canadian and Australian dollar-based costs for a significant portion of the next three years. The average hedge rates vary depending on when the contracts were put in place. For hedges in place for future years, average hedge rates are higher because some of the contracts were added over time as the US dollar weakened. The average rates of currency contracts over the next three years are $0.68 for Australian dollar contracts and $0.76 for Canadian dollar contracts. Beyond the next three years, most of our Canadian and Australian dollar-based costs are subject to market currency exchange rates, and consequently costs reported in US dollars for our Australian operations and our Canadian operations could increase if currency exchange rates against the US dollar remain at present levels.
Inflationary Cost Pressures
Our industry is experiencing significant inflationary cost pressures for many commodities and consumables used in the production of gold, as well as, in some cases, constraints on supply. These pressures have led to a trend of higher production costs reported by many gold producers, and we have been actively seeking ways to mitigate these cost pressures. In the case of diesel fuel and propane, we put in place hedge positions that have been successful in mitigating the impact of recent price increases to a significant extent. For other cost pressures, we have been focusing on supply chain management and continuous improvement initiatives to mitigate the impact on our business.
Fuel
We consume on average about 2 million barrels of diesel fuel and approximately 24 million gallons of propane annually across all our mines.
Diesel fuel is refined from crude oil and is therefore subject to the same price volatility affecting crude oil prices. With global demand increasing and oil supply disruptions in 2005, oil prices rose from $43 per barrel at the start of the year to $61 per barrel at the end of the year. To help control the costs of fuel consumption, we have a fuel hedge position totaling 2 million barrels, which represents about 25% of our total estimated consumption in each of the next four years. The fuel hedge contracts are primarily designated for our Goldstrike, Round Mountain, and Kalgoorlie mines. The average hedge rate of our fuel contracts is $44 per barrel. In 2005, we realized benefits in the form of fuel hedge gains totaling $9 million (2004: $4 million; 2003: nil), when fuel hedge prices were compared to market prices. These gains are reflected in our operating costs. If the trend of high diesel fuel prices continues, this could impact future gold production costs.

Propane prices rose from $0.76 per gallon at the start of 2005 to $1.04 at the end of the year. Propane prices have increased mainly due to a substitution of propane for natural gas by some consumers that caused an increase in demand for propane. To help control the costs of propane consumed at our mines, we have a propane hedge position totaling 17 million gallons, which represents about 70% of our estimated future propane consumption through to the end of 2006, at an average price of $0.79 per gallon. We realized hedge gains totaling $1 million in 2005 (2004 and 2003: nil), when market prices were compared to our propane hedge prices. These gains are reflected in our operating costs.
Electricity
We purchase about 1.6–1.7 million megawatt hours of electricity annually across all our mines. We buy electricity from regional power utilities, and in addition at some mines we generate our own power. Fluctuations in electricity prices are generally caused by local economic factors and impact costs to produce gold. Electricity prices have generally been rising in recent years due to increases in the price of diesel fuel, coal and natural gas, which are used by many power generators, as well as excess demand for electricity. Natural gas prices rose in North America in 2005, as Hurricane Katrina and other factors caused a tightening of supply that has not fully recovered yet.
To partially mitigate the impact of rising electricity costs, we built a 115-megawatt natural gas-fired power plant that became operational in the fourth quarter of 2005. This power plant provides Goldstrike with the flexibility to generate its own power or buy cheaper power from other producers, with the goals of minimizing the cost of power consumed and enhancing the reliability of electricity availability at the mine.
Consumables
With increasing demand for tires and limitations in supply from tire manufacturers, costs have been rising and some companies have experienced difficulty securing tires. We have been seeking to mitigate this cost pressure by finding ways to extend tire lives and looking at various alternatives for supply. In 2006, our focus will be to complete a tire tender process and sign long-term agreements with preferred tire suppliers to ensure that we continue to receive an adequate supply of tires for our mines and development projects. The limited availability of tires has not had a significant impact on productivity at our mines.
Prices for certain other consumables, such as cyanide and explosives, have also been generally increasing, which in turn leads to higher mining and processing costs. In 2005, we benefited from contract pricing for cyanide that was below the prevailing market price. For 2006, we expect to procure most of our cyanide at market prices, with price increases due to higher costs for caustic soda and natural gas. For explosives, we experienced price increases in 2005 because natural gas and ammonia are both used in the production of ammonium nitrate explosives. We are evaluating alternatives to reduce consumables costs through supply chain and continuous improvement initiatives.
Labor Costs
With high demand for experienced miners and relatively inflexible supply, the industry has been facing upward pressure on labor costs, as well as higher turnover rates in some cases, due to the strong demand. Labor cost pressures have been most significant in Australia.

US Dollar Interest Rates
Short-term US dollar interest rates rose in 2005 as the US Federal Reserve continued its tightening cycle. We expect long-term interest rates to rise as the front end of the curve rises due to inflation risks. Volatility in interest rates mainly affects interest receipts on our cash balances ($1 billion cash at the end of 2005), and interest payments on variable-rate debt ($0.6 billion of variable-rate debt at the end of 2005). Based on the relative amounts of these variable-rate financial assets and liabilities, rising interest rates would have an overall positive impact on our results. The relative amounts of variable-rate financial assets and liabilities may change in the future depending upon the amount of operating cash flow we generate as well as amounts invested in capital expenditures.
In response to the volatility in interest rates, we have used interest rate swaps to alter the relative amounts of variable-rate financial assets and liabilities and to mitigate the overall impact of changes in interest rates. Management of interest-rate risk takes into account the term structure of variable-rate financial assets and liabilities. On $425 million of our cash balances, we have fixed the interest rate through 2007 at 3.63% using interest rate swaps. These interest rate swaps generated hedge gains, when rates under the swaps are compared to market interest rates, totaling $6 million in 2005; $19 million in 2004; and $18 million in 2003. In the future, we may alter the notional amounts of interest rate swaps outstanding as the relative amounts of variable-rate assets and liabilities change to manage interest rate risk.

Executive Overview and 2006 Outlook
In 2005, we produced 5.5 million ounces of gold at average total cash costs of $227 per ounce, in line with our original guidance for the year. The contribution to gold production from three new mines, Tulawaka, Lagunas Norte and Veladero, more than offset slightly lower production from Eskay Creek and Plutonic. Through our currency and commodity hedge programs, and supply chain initiatives, we were able to mitigate to some extent the impact of inflationary cost pressures.
We had earnings of $401 million ($0.75 per share) and generated operating cash flow of $726 million ($1.35 per share) in 2005.

At year-end, on a pro forma basis, we had proven and probable reserves, including reserves of 88.6 million ounces at our existing properties and our acquired interest in Placer Dome reserves of 50.1 million ounces of goldb, of 138.7 million ounces of golda, b, based on a $400 per ounce gold price assumption and 6.15 billion pounds of copperb, after adjusting for the anticipated sale of certain assets to Goldcorp.
We continued to effectively support and shape our growth profile, including a focus on Russia and Central Asia, and to make significant progress on the development of our new generation of mines. The Tulawaka, Lagunas Norte and Veladero mines began production in 2005, and we expect our fourth new mine, Cowal in Australia, to commence its first gold production in first quarter 2006. We continued work on advancing our other projects, including

Cash Flow
In 2005, our cash position decreased by $361 million. We generated $726 million of operating cash flow, $217 million higher than in 2004, mainly because of higher gold sales volumes and realized gold prices, partly offset by higher total cash costs. Capital expenditures were $1.1 billion, $280 million higher than in 2004, due to the levels of construction activity at our development projects. We received $93 million from financing activities in 2005, including $92 million in proceeds on the exercise of stock options and $179 million in proceeds from various financing facilities used to fund construction at our development projects, partly offset by $59 million of scheduled repayments on financing facilities and dividend payments of $118 million.
Acquisition of Placer Dome
In early 2006, we completed the acquisition of Placer Dome. We expect that the total cost of acquisition will be about $10.1 billion. We will consolidate Placer Dome’s results of operations from January 20, 2006. Placer Dome is one of the world’s largest gold mining companies, with gold mineral reserves of 60.4 million ounces and copper reserves of 6.15 billion pounds at December 31, 2005. Placer Dome produced 3.6 million ounces of gold and 359 million pounds of copper in 2005. It has 12 producing mines based in North America, South America, Africa and Australia/New Guinea, and three significant projects that are in various stages of exploration/development. Its most significant mines are Cortez in the United States, Zaldívar in Chile, Porgera in New Guinea, North Mara in Tanzania and South Deep in South Africa. The most significant projects are Cortez Hills and Donlin Creek in the United States, and Pueblo

Viejo in the Dominican Republic. We plan to sell Placer Dome’s Canadian mines to Goldcorp Inc. (“Goldcorp”), as well as certain other interests in mineral properties. As at February 17, 2006, Placer Dome had a committed gold hedge position totaling approximately 6.2 million ounces. We plan to focus on reducing this acquired hedge position further over time, consistent with the plans for our existing gold hedge position.
We believe that the business combination between Barrick and Placer Dome is a unique opportunity to create a Canadian-based leader in the global gold mining industry. This business combination further strengthens our position in the industry, with respect to reserves, production, our development pipeline and balance sheet. We expect that the combination will yield synergies from the combined companies of approximately $200 million annually beginning in 2007. We expect to realize the synergies in the following areas:

n |  | Operations — through the optimization and sharing of mining and processing infrastructure in common jurisdictions, including Nevada, Australia and Tanzania;
n |  | Exploration — by carefully assessing our exploration spending and focusing on the most prospective areas and reducing the overall exploration spending of the combined enterprise;
n |  | Administration — by eliminating duplication of offices and overheads;
n |  | Procurement — through the improved purchasing power of the larger enterprise; and
n |  | Finance and Tax — by realizing tax synergies in certain jurisdictions, opportunities for debt optimization and a lower overall cost of capital resulting from a larger balance sheet.

Sale of Certain Placer Dome Operations to Goldcorp
Goldcorp has agreed, subject to certain conditions, to acquire all of Placer Dome’s Canadian operations (other than its offices in Vancouver and Toronto), including all mining, reclamation and exploration properties, Placer Dome’s interest in the La Coipa mine in Chile, and a 40% interest in the Pueblo Viejo project in the Dominican Republic, for cash consideration of about $1.5 billion. We expect that the sale of these operations to Goldcorp will close in the first half of 2006. Until closing, we expect to consolidate the results of these operations, and we do not expect to record any significant gain or loss on closing of the sale.

The pro forma information has been presented for illustrative purposes only to show the effect of the acquisition of 100% of Placer Dome by Barrick as though it had occurred on January 1, 2005 for the pro forma unaudited selected income statement information. The unaudited selected balance sheet information as at December 31, 2005 was prepared using the consolidated balance sheets of Barrick and Placer Dome as at December 31, 2005. Certain adjustments have been reflected in this pro forma information to illustrate the effects of harmonizing accounting policies and purchase accounting, and to reflect the impact of the sale of certain Placer Dome operations to Goldcorp, where the impact could be reasonably estimated. We will complete an exercise to value the identifiable assets and liabilities acquired, including any goodwill that may arise upon the acquisition.
This unaudited pro forma consolidated financial statement information is not intended to be indicative of the results that would actually have occurred, or the results expected in future periods. Results of operations for Placer Dome could differ materially from those recorded in 2005 due to the effects of purchase accounting, the harmonization of Placer Dome’s accounting policies with Barrick’s accounting policies, and other factors such as the key economic trends described on pages 34 to 39. As a result of the bid process, Placer Dome’s 2005 income statement reflects approximately $21 million of non-recurring transaction-related costs. Any potential synergies that may be realized, and integration costs that may be incurred, have been excluded from the pro forma information. The information prepared is only a summary, and more details can be found in note 3 to the Financial Statements.

In 2006, we expect to produce between 8.6 to 8.9 million ounces of gold at total cash costs of $275 to $290 per ounce and approximately 350 million pounds of copper at total cash costs of about $1.10 per pound including the contribution from the Placer Dome operations after adjusting for the sale of certain operations to Goldcorp. Copper total cash costs per pound include the impact of purchase accounting fair value adjustments. Excluding these one-time, non-cash accounting adjustments, copper cash costs would be lower by approximately $0.35 per pound. The overall average total cash costs per ounce of Placer Dome’s gold production is higher than the average for the existing Barrick mines, and consequently, we expect that the overall average total cash costs per ounce of our gold production will increase following the acquisition. We expect the overall amortization expense may increase following the completion of the purchase price allocation.
Consolidated Gold Production and Sales
By replacing gold reserves depleted by production year over year, we can maintain production levels over the long term. If depletion of reserves exceeds discoveries over the long term, then we may not be able to sustain gold production levels. Reserves can be replaced by expanding known ore bodies, acquiring mines or properties or locating new deposits. Once a site with gold mineralization is discovered, it may take several years from the initial phases of drilling until production is possible, during which time the economic feasibility of production may change. Substantial expenditures are required to establish proven and probable reserves and to construct mining and processing facilities. Given that gold exploration is speculative in nature, some exploration projects may prove unsuccessful.
Our financial performance is affected by our ability to achieve targets for production volumes and total cash costs. We prepare estimates of future production and total cash costs of production for our operations. These estimates are based on mine plans that reflect the expected method by which we will mine reserves at each mine, and the expected costs associated with the plans. Actual gold production and total cash costs may vary from these estimates for a number of reasons, including if the volume of ore mined and ore grade differs from estimates, which could occur because of changing mining rates; ore dilution; metallurgical and other ore characteristics; and short-term mining conditions that require different sequential development of ore bodies or mining in different areas of the mine. Mining rates are impacted by various risks and hazards inherent at each operation, including natural phenomena such as inclement weather conditions, floods, and earthquakes and unexpected labor shortages or strikes. Total cash costs per ounce are also affected

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 43

#####

by ore metallurgy that impacts gold recovery rates, labor costs, the cost of mining supplies and services, foreign currency exchange rates and stripping costs incurred during the production phase of the mine. In the normal course of our operations, we attempt to manage each of these risks to mitigate, where possible, the effect they have on our operating results.
In the first half of 2005, ounces produced and sold were similar to the first half of 2004. In the second half of 2005 compared to the same period in 2004, ounces produced increased by about 32%, while ounces sold increased by 26% as production and sales began at Lagunas Norte and increased at the Goldstrike Open Pit while only production began at Veladero.
In 2005, we sold most of our production at market prices, and delivered approximately 0.8 million ounces into gold sales contracts. We realized an average gold sales price of $439 per ounce, $48 higher than in 2004, mainly due to higher market gold prices. The price realized for gold sales in 2006 and beyond will depend on market conditions and the selling prices of any gold sales contracts into which we voluntarily deliver, which could be below prevailing spot market prices.

2. |  | Total cash costs per ounce excludes amortization — see page 45.

Total cash costs for 2005 were in line with the original full-year guidance, but higher than in 2004, primarily due to inflationary cost pressures experienced in 2005, partly offset by the start-up of low-cost production from Lagunas Norte, the availability of higher-grade ore at Goldstrike Open Pit, and the impact of the change in accounting for stripping costs (see page 65).
Total Cash Costs Performance Measures
Total cash costs include all costs absorbed into inventory, including royalties, by-product credits, mining taxes and accretion expense, except for amortization. Total cash costs per ounce is calculated by dividing the aggregate of these costs by gold ounces sold. Total cash costs and total cash costs per ounce are calculated on a consistent basis for the periods presented. On our income statement we present amortization separately from cost of sales. Some companies include amortization in cost of sales, which results in a different measurement of cost of sales on the income statement. We have provided below a reconciliation to illustrate the impact of excluding amortization from cost of sales and total cash costs per ounce statistics.
In managing our mining operations, we disaggregate cost of sales between amortization and the other components of cost of sales. We use total cash costs per ounce statistics as a key performance measure internally to monitor the performance of our mines. We use the statistics to assess how well our mines are performing against internal plans, and also to assess the overall effectiveness and efficiency of our mining operations. We also use amortization cost per ounce statistics to monitor business performance. By disaggregating cost of sales into these two components and separately monitoring them, we are able to better identify and address key performance trends. We believe that the presentation of these statistics in this manner in our MD&A, together with commentary explaining trends and changes in the statistics, enhances the ability of investors to assess our performance. These statistics also enable investors to better understand year-on-year changes in cash production costs, which in turn affect our profitability and ability to generate cash flow.
The principal limitation associated with total cash costs per ounce statistics is that they do not reflect the total costs to produce gold, which in turn impacts the earnings of Barrick. We believe that we have compensated for this limitation by highlighting the fact that total cash costs exclude amortization as well as providing details of the financial effect. We believe that the benefits of providing disaggregated information outweigh the limitation in the method of presentation of total cash costs per ounce statistics.

Results of Operating Segments
In our Financial Statements, we present a measure of historical segment income that reflects gold sales at average consolidated realized gold prices, less segment expenses and amortization of segment property, plant and equipment. Our segments mainly include producing mines and development projects. We monitor segment expenses using “total cash costs per ounce” statistics that represent segment cost of sales divided by ounces of gold sold in each period. The discussion of results for producing mines focuses on this statistic in explaining changes in segment expenses, and should be read in conjunction with the mine statistics presented on pages 26-27.
Conducting mining activities in certain countries outside North America subjects us to various risks and uncertainties that arise from carrying on business in foreign countries including: uncertain political and economic environments; war and civil disturbances; changes in laws or fiscal policies; interpretation of foreign taxation legislation; and tax implications on repatriation of foreign earnings. We monitor these risks on an ongoing basis and mitigate their effects where possible, but events or changes in circumstances could materially impact our results and financial condition.
For development projects, we prepare estimates of capital expenditures, reserves and costs to produce reserves. We also assess the likelihood of obtaining key governmental permits, land rights and other government approvals. Estimates of capital expenditures are based on studies completed for each project, which also include estimates of annual production and production costs. Adverse changes in any of the key assumptions in these studies or other factors could affect estimated capital expenditures, production levels and production costs, and also the economic feasibility of a project. We take steps to mitigate potentially adverse effects of changes in assumptions or other factors. Prior to the commencement of production, the segment results for development projects reflect expensed mine start-up costs.
North America
In 2005, the region produced 2,863,000 ounces (2004: 2,963,000 ounces) at total cash costs of $244 per ounce (2004: $223 per ounce). Gold production in 2005 was within full-year production guidance and slightly lower than 2004 as higher production at Goldstrike Open Pit was offset by slightly lower production at Goldstrike Underground, the processing of fewer tons at Eskay Creek in 2005 and the cessation and sale of mining operations at Holt-McDermott in 2004. In 2005, total cash costs per ounce increased over 2004 due to lower production levels at Goldstrike Underground and inflationary cost pressures, partly offset by higher toll milling credits and the impact of the change in accounting for stripping costs (see page 65). Total cash costs per ounce were slightly better than the full-year guidance as a result of higher production at Goldstrike Open Pit, partly offset by higher costs at Goldstrike Underground and Round Mountain.

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 45

#####

Goldstrike Open Pit, United States
Production was higher in 2005 than 2004 as a result of mining in areas of the pit with higher ore grades, on completion of the ninth west layback in the second half of the year, partly offset by lower tons processed in the first half of the year due to above average rainfall that impacted mining rates, harder ore encountered that impacted milling rates, and higher toll milling volumes in 2005. Total cash costs per ounce in 2005 were lower than both guidance and 2004 due to the higher production levels and higher toll milling credits, as well as the impact of the change in accounting for stripping costs (see page 65), partly offset by the impact of inflationary cost pressures and higher royalties due to higher market gold prices.
Goldstrike Underground, United States
In 2005, there was an increase in drift-and-fill mining due to mine sequencing changes to compensate for difficult ground conditions. Lower mining rates due to the increase in drift-and-fill mining, as well as a temporarily plugged backfill raise, were partly offset by a drawdown of stockpiles in the first half of 2005, resulting in lower gold production than guidance and 2004. Lower production levels combined with inflationary cost pressures, higher ground support costs due to difficult ground conditions, an increase in drift-and-fill mining, and higher royalty costs due to higher market gold prices, resulted in higher total cash costs per ounce in 2005 than in 2004, and slightly higher than the guidance for 2005.
Western 102 Power Plant in Nevada, United States
The 115-megawatt natural gas-fired power plant in Nevada to supply our Goldstrike mine was completed and began operating in December 2005. The construction cost was $96 million.
Eskay Creek, Canada
As the mine approaches the end of its reserve life in 2008, lower availability of high-grade direct-to-smelter ore resulted in the mining of more lower-grade ore tons, leading to lower gold production in 2005. Total cash costs per ounce in 2005 were lower than the guidance for the year, but higher than in 2004 due to the lower production levels and lower silver by-product credits (volume-related), partly offset by lower smelter costs and higher silver prices.
Round Mountain (50% Owned), United States
In 2005, higher recoveries of gold from ore placed on the leach pad were offset by slightly lower tons placed on the pad, resulting in slightly lower production in 2005 over 2004. Tons processed and recovery rates each period do not necessarily correlate to the ounces produced in the period as there is a time delay between placing tons on the leach pad and producing gold. Total cash costs per ounce were slightly lower than the guidance for 2005, although higher than 2004, mainly due to the impact of inflationary cost pressures and the change in accounting for stripping costs (see page 65). The joint venture partners have agreed to proceed with a pit expansion project, resulting in an increase in gold reserves, and an extension of the expected mine life from 2010 to 2015.
East Archimedes, United States
In 2004, we made a decision to proceed with the East Archimedes project in Nevada. The project is an open-pit, heap leach operation exploiting the East Archimedes deposit, a deeper continuation of the ore mined previously at Ruby Hill. Construction capital is estimated at about $75 million over an expected two-year construction phase. Gold production is expected to commence by mid-2007. Project highlights include:

n |  | Construction capital costs of $35 million were incurred in 2005.
n |  | The workforce is in place and all major equipment is in service.
n |  | The remaining balance of the mining fleet was received in fourth quarter 2005.
n |  | Pre-strip activities are in progress.

South America
The region produced 1,234,000 ounces in 2005 (2004: 646,000 ounces) at total cash costs of $126 per ounce (2004: $111 per ounce). After achieving production start-up ahead of schedule in mid-June 2005, Lagunas Norte made a significant contribution to the region’s results in the second half of 2005. Veladero had its first gold pour in September 2005 and commenced full production in fourth quarter 2005. We expect these two mines to make a signifi-cant contribution to production for the region in 2006 and beyond. In 2005, gold production exceeded guidance for the year due to higher than expected production at Pierina, while total cash costs per ounce were within the range of guidance provided for the year. Total cash costs per ounce were higher than 2004 due to higher total cash costs per ounce at Pierina.
Pierina, Peru
Although mining at Pierina occurred in higher-grade areas of the pit in 2005, lower quantities of run-of-mine ore were placed on the leach pad than in 2004, which led to slightly lower production in 2005. Total cash costs per ounce increased over 2004 due to the impact of inflationary cost pressures, combined with the impact of higher equipment maintenance, labor and ground support costs, partly offset by higher silver by-product credits and the positive impact of the change in accounting for stripping costs (see page 65). Mining costs per ton of ore were higher in 2005 as tons of waste mined increased over 2004. Gold production and total cash costs per ounce in 2005 were slightly higher than guidance.
Lagunas Norte, Peru
The Lagunas Norte mine achieved start-up in June 2005, ahead of schedule, with a capital construction cost of $323 million. Lagunas Norte produced 550,000 ounces in 2005, at total cash costs of $110 per ounce, with the mining of higher-grade near-surface ore. Both gold production and total cash costs per ounce were within the range of guidance for the year.
Veladero, Argentina
The Veladero mine had its first gold pour, ahead of schedule, in September 2005. Commissioning activities are complete and the mine is ramping up production levels. Capital construction costs for the project were $547 million. The mine produced 56,000 ounces in 2005.
Pascua-Lama, Chile/Argentina
In 2004, we made a decision to proceed with the development of the Pascua-Lama project in Chile/ Argentina, contingent on obtaining the necessary permits, approvals and fiscal regimes. We recently received approval of the environmental impact assessment from Chilean environmental regulatory authorities and we are committed to working within the framework of the Resolution granted to us. The Resolution, which was issued on February 17, 2006, imposes certain conditions in connection with the development of the project. We are currently assessing the implications of such conditions and it is possible that, following completion of such assessment, reserves for US reporting purposes could be reduced by up to 1 million ounces. It is expected that reserves for Canadian reporting purposes would remain unchanged. Approval of the environmental impact assessment by Argentine regulatory authorities is targeted for second quarter 2006. The timing of receipt of such approval, as well as the resolution of some of the other external issues, such as permitting and licensing, cross-border operating issues and fiscal, tax and royalty issues are largely beyond our control.
Capital and operating cost estimates for the Pascua-Lama project were based on the cost and commodity price environment prevailing at the time of the updated feasibility study, which was finalized in June 2004. The design of the project has been optimized in the course of the permitting process to incorporate additional operating and construction efficiencies, additional environmental mitigation measures, and other project improvements. We are in the course of updating cost estimates to reflect such changes, inflationary cost pressures and higher commodity prices. Although such factors will result

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 47

#####

in some increase in capital and operating cost estimates, based on the current cost and commodity price environment, and combined with other efficiencies, we do not expect significant changes to the overall economics of the project.
Australia/Africa
The region produced 1,332,000 ounces in 2005 (2004: 1,349,000 ounces) at total cash costs of $280 per ounce (2004: $243 per ounce). Lower production in 2005 was mainly due to the discontinuation of open pit mining at Plutonic in second quarter 2005 and lower production at Kalgoorlie in the second half of the year, partly offset by new production from Tulawaka. Total cash costs per ounce were higher in 2005 mainly because of inflationary cost pressures, higher exchange rates under hedge contracts, lower tons mined and produced at Bulyanhulu and lower production levels at Plutonic after open-pit mining ended in second quarter 2005.
Kalgoorlie (50% Owned), Australia
Mill throughput was higher in 2005 due to lower maintenance downtime than in 2004; but gold production was lower in 2005 than 2004. Lower production was the result of mining in lower-grade areas of the pit and lower recovery rates experienced in the second half of 2005, partly offset by higher mill throughput due to improved mill utilization and the positive impact of finer ore sizes. Total cash costs per ounce were within the range of guidance for 2005. The combined impact of lower production levels, inflationary cost pressures and higher exchange rates under hedge contracts, and the effect of the change in accounting for stripping costs (see page 65), resulted in higher total cash costs per ounce in 2005 than in 2004. We are assessing process changes, controls and other management measures for the roaster facility to reduce mercury emissions. Kalgoorlie has installed a first-stage mercury scrubber on its carbon kiln and is assessing the performance of that unit to determine what additional steps might be appropriate. The assessment is continuing, after which we will be able to estimate any capital requirements and operating cost impact associated with such measures.
Plutonic, Australia
Gold production at Plutonic was lower in 2005, as the mine processed fewer tons of ore after open-pit mining ended in second quarter 2005, also resulting in a higher proportion of ore feed from the underground, which is of a higher grade than open-pit ore. Total cash costs per ounce were higher in 2005 than 2004, mainly due to the combined effect of the lower gold production levels, higher equipment maintenance, higher exchange rates under hedge contracts and inflationary cost pressures, partly offset by lower operating costs related to cessation of open-pit mining and the impact of the change in accounting for stripping costs (see page 65). Total cash costs per ounce were slightly higher than guidance while gold production was within the guidance range.
Bulyanhulu, Tanzania
Gold production was lower in 2005, mainly due to a combination of lower tons mined and lower ore grades. Tons mined were lower in 2005, mainly due to reduced equipment availability, a hoist gearbox failure and labor issues due to roster changes in 2005. Ore grades were also lower in 2005 as tons were mined from lower-grade stopes. Total cash costs per ounce in 2005 were higher than guidance and 2004 due to the lower gold production levels, inflationary cost pressures and higher administration and underground maintenance costs.

Cowal, Australia
The Cowal project in Australia remains on schedule for its first gold production in first quarter 2006. Construction costs are anticipated to be about ten per cent over the guidance of about $305 million as a result of the impact of inflationary cost pressures in Australia. We have been taking steps to mitigate cost increases where possible. Project highlights at the end of 2005 include:

n |  | Capitalized costs, including capitalized interest, were $258 million in 2005.
n |  | Construction of the systems necessary to process oxide ore were over 85% complete.
n |  | Pre-commissioning of the process plant started in mid-December 2005 and the electrical transmission line was commissioned in January 2006.
n |  | Plant-site concrete and buildings were 98% complete.
n |  | About one million tons of ore have been stockpiled to date.

Buzwagi, Tanzania
The drill program at Buzwagi is substantially complete and the results are being compiled. A pre-feasibility study is complete and will be used to support a reserve of 2.4 million ounces under Canadian reporting standards.1 The permitting process is underway with the Tanzanian authorities and an engineering project consultant has been assigned to initiate a feasibility study to support a production decision.
Kabanga (50% Owned), Tanzania
In April 2005, we entered into a joint-venture agreement with Falconbridge Limited (“Falconbridge”) with respect to the Kabanga nickel deposit and related concessions in Tanzania. Falconbridge acquired a 50% indirect interest in respect of the Kabanga project for $15 million cash and a funding commitment. Falconbridge will be the operator of the joint venture. In 2004, the Kabanga project had an estimated inferred resource of 26.4 million tonnes grading 2.6% nickel.1 This resource is currently being updated, based on the field work to be completed in 2006.
Over the next several years, Falconbridge has agreed to fund and conduct a further $50 million work plan that will include additional exploration and infill drilling, and technical work to update the resource model for Kabanga and bring the project towards feasibility. Falconbridge has initiated the establishment of a dedicated team in Tanzania to coordinate and advance the work plan. After expenditure of $50 million, Falconbridge will decide on whether to proceed with the project. If Falconbridge proceeds with the project, they will fund the next $95 million of any project development expenditures to advance the Kabanga project. Thereafter, Falconbridge and Barrick will share equally in joint-venture revenues and expenditures.
Russia/Central Asia
In 2005, we continued to focus on developing our operations in the region. In April 2005, we spent $50 million to increase our ownership in Highland Gold Mining PLC (“Highland Gold”) from 14% to 20%. Our 20% ownership interest is reflected in our Financial Statements and production statistics on an equity basis. We continue to work with Highland Gold on projects where we have the option to acquire a joint interest. We established a project office in Moscow and appointed a Regional Vice President to lead the development of our business in the region.

Non-hedge derivative gains |  | $ | (6 | ) |  | $ | (5 | ) |  | $ | (71 | ) |  | The gains and losses arise primarily due to changes in commodity prices, currency exchange rates and interest rates.
Gains on asset sales |  |  | (5 | ) |  |  | (36 | ) |  |  | (36 | ) |  | In 2005, we sold certain land positions in Australia. In 2004, we sold various mining properties, including the Holt-McDermott mine in Canada and certain land positions around our inactive mine sites in the United States. In 2003, we sold various mining properties, including several land positions around inactive mine sites in the United States, as well as the East Malartic Mill and Bousquet mine in Canada. The majority of these land positions were fully amortized in prior years and therefore any proceeds generated gains on sale, before selling costs and taxes.

Income tax expense increased in 2005 in comparison to the tax recoveries in 2004, as the 2004 tax recoveries arose primarily with respect to the change in Australian tax status and the outcome of tax uncertainties. Our underlying tax rate decreased to 21% in 2005 in part due to the impact of a lower amount of deliveries into gold sales contracts in a low tax-rate jurisdiction at prices below the prevailing spot market gold price than in 2004. A shift in the geographic mix of gold production, and therefore income before taxes, towards jurisdictions with lower tax rates also contributed to a reduction in the underlying tax rate.
As gold prices increase, our underlying tax rate also increases, reaching about 29% with market prices at or above $475 per ounce. This expected underlying rate excludes the effect of gains and losses on non-hedge derivatives, the effect of delivering into gold sales contracts in a low tax-rate jurisdiction at prices below prevailing market prices, and any release of deferred tax valuation allowances.
We record deferred tax charges or credits if changes in facts or circumstances affect the estimated tax basis of assets and therefore the amount of deferred tax assets or liabilities or because of changes in valuation allowances reflecting changing expectations in our ability to realize deferred tax assets. In 2005, we released valuation allowances totaling $32 million, of which $31 million related to Argentina, in anticipation of higher levels of future taxable income after production began at Veladero, and also due to the impact of higher market gold prices. In 2004, we recorded a tax credit of $141 million on final resolution of a Peruvian tax assessment in our favor, as well as the reversal of other accrued costs totaling $21 million ($15 million post-tax). We also recorded credits of $81 million due to a change in tax status in Australia following an election that resulted in a revaluation of assets for tax purposes; and also an election to file tax returns in US dollars, rather than Australian dollars. In 2005, we revised our estimate of the revaluation of assets for tax purposes due to the change in status, and recorded a further deferred tax credit of $5 million.
The interpretation of tax regulations and legislation and their application to our business is complex and subject to change. We have significant amounts of deferred tax assets, including tax loss carry forwards, and also deferred tax liabilities. Potential changes to any of these amounts, as well as our ability to realize deferred tax assets, could significantly affect net income or cash flow in future periods. For more information on tax valuation allowances, see page 71.

Our financial results for the last eight quarters reflect the following general trends: rising spot gold prices with a corresponding rise in prices realized from gold sales; and rising gold production and sales volumes as our new mines began production in 2005. These historic trends are discussed elsewhere in this MD&A. The quarterly trends are consistent with explanations for annual trends over the last two years. Net income in each quarter also reflects the timing of various special items that are presented in the table on page 54.
Fourth Quarter Results
In fourth quarter 2005, we produced 1.65 million ounces at total cash costs of $221 per ounce1 compared to 1.17 million ounces at total cash costs of $223 per ounce in the prior-year quarter. Revenue for fourth quarter 2005 was $776 million on gold sales of 1.65 million ounces, compared to $501 million in revenue on gold sales of 1.2 million ounces for the prior-year quarter. Sales volumes increased due to the contribution from new mines that began production in 2005. During the quarter, spot gold prices averaged $486 per ounce. We realized an average price of $467 per ounce during the quarter compared to $417 per ounce in the prior-year quarter mainly due to higher spot gold prices. Earnings for fourth quarter 2005 were $175 million ($0.32 per share on a diluted basis), $19 million ($0.03 per share on a diluted basis) higher than the prior-year quarter. The increase in earnings over the prior-year quarter reflects higher gold sales volumes and realized gold prices, partly offset by the impact of special items.

In fourth quarter 2005, we generated operating cash flow of $269 million compared to operating cash flow of $123 million in the prior-year quarter. Higher operating cash flow primarily relates to the combined effect of higher gold sales volumes and higher realized gold prices.

We plan to fund the expected capital expenditures for 2006 from a combination of our $1 billion cash position at the end of 2005, and operating cash flow that we expect to generate in 2006. We are considering putting in place project financing for a portion of the mine construction costs at Pascua-Lama.
On February 14, 2006, we entered into an agreement with Antofagasta plc (“Antofagasta”) to acquire 50% of Tethyan Copper Company’s (“Tethyan”) Reko Diq project and associated mineral interests in Pakistan in the event that Antofagasta is successful in its bid to acquire Tethyan. If Antofagasta’s bid is successfully completed, we will reimburse Antofagasta approximately $100 million in cash for 50% of the acquisition, including the claw-back right to be acquired or extinguished from BHP Billiton who has a right to claw-back a material interest in certain Tethyan’s mineral interests.
Financing Activities
The most significant financing cash flows in 2005 were $179 million on issue of new long-term debt obligations, $92 million received on the exercise of employee stock options partly offset by dividend payments made totaling $118 million. We also made scheduled payments under our long-term debt obligations totaling $59 million in 2005.

Liquidity
Liquidity Management
Liquidity is managed dynamically, and factors that could impact liquidity are regularly monitored. The primary factors that affect liquidity include gold production levels, realized gold sales prices, cash production costs, future capital expenditure requirements, scheduled repayments of long-term debt obligations, our credit capacity and expected future debt market conditions. Working capital requirements have not historically had a material effect on liquidity. Counterparties to the financial instruments and gold sales contracts that we hold do not have unilateral and discretionary rights to accelerate settlement of financial instruments or gold sales contracts, and we are not subject to any margin calls.
Through the combination of a strong balance sheet and positive operating cash flows, we have been able to secure financing, as required, to fund our capital projects. We had three new mines start in 2005, with a fourth scheduled to start production in first quarter 2006. The costs of construction for these projects were financed through a combination of operating cash flows and the issuance of long-term debt financing. While we consider our liquidity profile to be sound with no reasonably foreseeable trends, demands, commitments, events or circumstances expected to prevent us from funding the capital needed to complete our projects and implement our strategy, no assurance can be given that additional capital investments will not be required to be made at these or other projects. If we are unable to generate enough cash to finance such additional capital expenditures through operating cash flow and we are unable or choose not to issue common stock, we may be required to issue additional indebtedness. Any additional indebtedness would increase our debt payment obligations, and may negatively impact our results of operations.
Capital Resources
Adequate funding is in place or available for all our development projects. We plan to put in place project financing for a portion of the expected construction cost of Pascua-Lama; however, if we are unable to do so because of unforeseen political or other challenges, we expect to be able to fund the capital required through a combination of existing capital resources and future operating cash flows. We may also invest capital in Russia and Central Asia in 2006 to acquire interests in mineral properties as we develop our business unit there. We expect that any capital required will be funded from a combination of our existing cash position and operating cash flow in 2006.
The total estimated acquisition cost of Placer Dome is $10.1 billion of which approximately $1.3 billion is the cash portion that is funded by drawing upon our $1 billion credit facility, with the balance from our cash position. We expect to close the sale of certain Placer Dome operations to Goldcorp in the first half of 2006 and receive cash consideration of about $1.5 billion from Goldcorp that will be used to repay amounts borrowed, with respect to the Placer Dome acquisition, on our $1 billion credit facility.

Credit Rating
At February 10, 2006 from major rating agencies:

Standard & Poor’s (“S&P”) |  | A–
Moody’s |  | Baa1
DBRS |  | A

In 2006, following the acquisition of Placer Dome, our ratings were reviewed and confirmed by Moody’s and DBRS. S&P lowered our rating from ‘A’ to ‘A–’, reflecting Placer Dome’s lower rating. Our ability to access unsecured debt markets and the related cost of debt financing is, in part, dependent upon maintaining an acceptable credit rating. A deterioration in our credit rating would not adversely affect existing debt securities or the terms of gold sales contracts, but could impact funding costs for any new debt financing. The key factors that are important to our credit rating include the following: our market capitalization; the strength of our balance sheet, including the amount of net debt and our debt-to-equity ratio; our net cash flow, including cash generated by operating activities and expected capital expenditure requirements; the quantity of our gold reserves; and our geo-political risk profile.
Financial Position
Key Balance Sheet Ratios

As at December 31 |  | 2005 |  |  | 2004 |
Non-cash working capital ($ millions)1 |  | $ | 151 |  |  | $ | 141 |
Net debt ($ millions)2 |  | $ | 764 |  |  | $ | 288 |
Net debt: equity ratio3 |  |  | 0.20:1 |  |  |  | 0.08:1 |
Current ratio4 |  |  | 3.12:1 |  |  |  | 4.66:1 |

1. |  | Represents current assets, excluding cash and equivalents, less current liabilities.
2. |  | Represents long-term debt less cash and equivalents.
3. |  | Represents net debt divided by shareholders’ equity.
4. |  | Represents current assets divided by current liabilities.

Non-cash working capital increased in 2005 mainly due to increases in inventory levels to support new mines that began production. Capital expenditures exceeded operating cash flow in 2005, resulting in a higher net debt position at the end of 2005. Lower cash balances, partly offset by higher inventory balances, caused our current ratio to decrease at the end of 2005.
Shareholders’ Equity
Outstanding Share Data
As at February 10, 2006, 827.7 million of our common shares, one special voting share and 1.4 million exchangeable shares (exchangeable into 0.7 million of our common shares) were issued and outstanding. As at February 10, 2006, options to purchase 20.2 million common shares were outstanding under our option plans, as well as options to purchase 0.3 million common shares under certain option plans inherited by us in connection with prior acquisitions. We intend to acquire the remaining 6% interest in Placer Dome through a compulsory acquisition procedure that would involve the issuance of additional common shares. For further information regarding the outstanding shares and stock options, please refer to the Financial Statements and our 2005 Management Information Circular and Proxy Statement.
Dividend Policy
In each of the last four years, we paid a total cash dividend of $0.22 per share — $0.11 in mid-June and $0.11 in mid-December. The amount and timing of any dividends is within the discretion of our Board of Directors. The Board of Directors reviews the dividend policy semi-annually based on the cash requirements of our operating assets, exploration and development activities, as well as potential acquisitions, combined with our current and projected financial position.
Comprehensive Income
Comprehensive income consists of net income or loss, together with certain other economic gains and losses that collectively are described as “other comprehensive income” or “OCI”, and excluded from the income statement.
In 2005, the other comprehensive loss of $100 million mainly included gains of $23 million on hedge contracts designated for future periods caused primarily by changes in currency exchange rates and fuel prices; offset by reclassification adjustments totaling $134 million for gains on hedge contracts designated for 2005 that were transferred to earnings in 2005; and a $8 million unrealized decrease in the fair value of investments.

#####

Included in other comprehensive income at December 31, 2005 were unrealized pre-tax gains on currency hedge contracts totaling $171 million, based on December 31, 2005 market foreign exchange rates. The related hedge contracts are designated against operating costs and capital expenditures primarily over the next three years, and are expected to help protect against the impact of strengthening of the Australian and Canadian dollar against the US dollar. The hedge gains are expected to be recorded in earnings at the same time as the corresponding hedged operating costs and amortization of capital expenditures are also recorded in earnings.

1. |  | Excludes any Placer Dome obligations and commitments.

Contractual Obligations and Commitments
(1) Long-term Debt and Interest
Our debt obligations do not include any subjective acceleration clauses or other clauses that enable the holder of the debt to call for early repayment, except in the event that we breach any of the terms and conditions of the debt or for other customary events of default. The Bulyanhulu and Veladero financings are collateralized by assets at the Bulyanhulu and Veladero mines, respectively. Other than this security, we are not required to post any collateral under any debt obligations. The terms of our debt obligations would not be affected by a deterioration in our credit rating. Projected interest payments on variable rate debt was based on interest rates in effect at December 31, 2005. Interest is calculated on our long-term debt obligations using both fixed and variable rates.
(2) Asset Retirement Obligations
Amounts presented in the table represent the undiscounted future payments for the expected cost of asset retirement obligations.
(3) Royalties and Other Long-term Liabilities
Virtually all of the royalty arrangements give rise to obligations as we produce gold. In the event that we do not produce gold at our mining properties, we have no payment obligation to the royalty holders. The amounts disclosed are based on expected future gold production, using a gold price range assumption of $450—$475 per ounce. The most significant royalty agreements are disclosed in note 6 to our Financial Statements. Based on 2005 production levels, an increase in market gold prices by $25 per ounce would result in an annual increase in royalty payments by approximately $8 million.

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 59

#####

Other long-term liabilities includes pension and post-retirement benefits funding in 2006. Funding beyond 2006 is not included in this table as it cannot be reasonably estimated given variable market conditions and actuarial assumptions. In 2006, we expect to make contributions to pension and post-retirement benefits plans totaling $6 million. Other long-term liabilities include derivative liabilities. Payments related to derivative contracts cannot be reasonably estimated given variable market conditions. Refer to note 16c to the Financial Statements.
(4) Capital Commitments
Purchase obligations for capital expenditures include only those items where binding commitments have been entered into. Commitments at the end of 2005 mainly related to construction at our development projects.
Capital Expenditures Not Yet Committed
We expect to incur capital expenditures during the next five years for Barrick projects, Placer Dome acquired projects and producing mines. The primary Barrick project is Pascua-Lama (refer to page 47 for further details) and the significant Placer Dome projects include Pueblo Viejo, Cortez Hills and Donlin Creek. We are currently in the process of reviewing the capital requirements for the acquired Placer Dome projects and producing mines.
Payments to Maintain Land Tenure and Mineral Property Rights
In the normal course of business, we are required to make annual payments to maintain title to certain of our properties and to maintain our rights to mine gold at certain of our properties. If we choose to abandon a property or discontinue mining operations, the payments relating to that property can be suspended, resulting in our rights to the property lapsing. The validity of mining claims can be uncertain and may be contested. Although we have attempted to acquire satisfactory title to our properties, some risk exists that some titles, particularly title to undeveloped properties, may be defective.
Contingencies — Litigation
We are currently subject to various litigation as disclosed in note 24 to the Financial Statements, and we may be involved in disputes with other parties in the future that may result in litigation. If we are unable to resolve these disputes favorably, it may have a material adverse impact on our financial condition, cash flow and results of operations.
Financial Instruments
We use a mixture of cash and long-term debt to maintain an efficient capital structure and ensure adequate liquidity exists to meet the cash needs of our business. A discussion of our liquidity and capital structure can be found on page 55. We use interest rate contracts to mitigate interest rate risk that is implicit in our cash balances and outstanding long-term debt. In the normal course of business, we are inherently exposed to currency and commodity price risk. We use currency and commodity hedging instruments to mitigate these inherent business risks. We also hold certain derivative instruments that do not qualify for hedge accounting treatment. These non-hedge derivatives are described in note 16 to our Financial Statements. For a discussion of certain risks and assumptions that relate to the use of derivatives, including market risk, market liquidity risk and credit risk, refer to notes 16e and 16f to our Financial Statements. For a discussion of the methods used to value financial instruments, as well as any significant assumptions, refer to note 16d to our Financial Statements.

Off-Balance Sheet Arrangements
Gold and Silver Sales Contracts
We have historically used gold and silver sales contracts as a means of selling a portion of our annual gold and silver production. The contracting parties are bullion banks whose business includes entering into contracts to purchase gold or silver from mining companies. Since 2001, we have been focusing on reducing the level of outstanding gold and silver sales contracts. The terms of our fixed-price gold and silver sales contracts enable us to deliver gold and silver whenever we choose over the primarily ten-year term of the contracts. In 2005, we reduced our fixed-price gold sales contracts position by 1.0 million ounces through delivery of 0.8 million ounces of our gold production and the conversion of 0.2 million ounces to floating spot price contracts.
Project Gold Sales Contracts
In July 2004, we announced a decision to proceed with the Pascua-Lama project (“Pascua-Lama”) subject to receiving required permits and clarification of the applicable fiscal regimes from the governments of Argentina and Chile.
In anticipation of building Pascua-Lama and in support of any related financing, we have 6.5 million ounces of existing fixed-price gold sales contracts specifically allocated to Pascua-Lama (the “Project

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 61

#####

Gold Sales Contracts”). The allocation of these contracts will help reduce gold price risk at Pascua-Lama and is expected to help secure the financing for its construction. We expect the allocation of these contracts to eliminate any requirement by lenders to add any incremental gold sales contracts in the future to support the financing of Pascua-Lama. The forward sales prices on our Project Gold Sales Contracts have not been fully fixed, and thus remain sensitive to long-term interest rates. For these contracts, increasing long-term interest rates in the fourth quarter resulted in a higher expected realizable sales price for these contracts. If long-term interest rates continue to rise, we anticipate the expected realizable sales price to increase.
As part of our Master Trading Agreements (“MTAs”), Project Gold Sales Contracts are not subject to any provisions regarding any financial go-ahead decisions with construction, or any possible delay or change in the project.
Key Aspects of Pascua-Lama Gold Sales Contracts

(as of December 31, 2005) |  |
Expected delivery dates.1 |  | 2009–2018, the term of the expected financing.
Future estimated average realizable selling price. |  | $378/oz.2
Mark-to-market value at December 31, 2005. |  | ($1,453) million.3

1. |  | The contract termination dates are in 2016–2019 in most cases, but we currently expect to deliver Pascua-Lama production against these contracts starting in 2009, subject to the timing of receipt of approvals of the environmental impact assessments, as well as the resolution of other external issues, both of which are largely beyond our control. Refer to page 47 for further details.
2. |  | Upon delivery of production from 2009–2018, the term of expected financing. Approximate estimated value based on current market US dollar interest rates and on an average lease rate assumption of 0.75%.
3. |  | At a spot gold price of $513 per ounce and market interest rates.

The allocation of 6.5 million ounces of gold sales contracts to Pascua-Lama involves: i) the identification of contracts in quantities and for terms that mitigate gold price risk for the project during the term of the expected financing (contracts were chosen where the existing termination dates are spread between the targeted first year of production and the expected retirement of financing for the project); ii) the segregation of these contracts from the remaining non-project gold sales contracts (the “Corporate Gold Sales Contracts”); and iii) the eventual settlement of proceeds from these contracts for the benefit of production.
Through allocation of these gold sales contracts to Pascua-Lama, we significantly reduce capital risk. It protects the gold price during the term of the forecasted financing, while leaving the remaining reserves fully levered to spot gold prices. The contracts represent just over 35% of the 18.3 million ounces of gold reserves at Pascua-Lama. These contracts do not impact any of the 684.7 million ounces of silver contained in gold reserves at Pascua-Lama.
Corporate Gold Sales Contracts and Floating Spot-Price Gold Sales Contracts
Fixed-price Corporate Gold Sales Contracts, which at December 31, 2005 totaled 6.0 million ounces, represent approximately one year of Barrick’s expected future gold production (excluding Placer Dome) and approximately 8.5% of our proven and probable reserves, in each case excluding Pascua-Lama and Placer Dome. At December 31, 2005, we had floating spot-price gold sales contracts under which we are committed to deliver 0.7 million ounces of gold over the next ten years at spot prices, less an average fixed-price adjustment of $127 per ounce. These floating spot-price contracts were previously fixed-price contracts, for which, under the price-setting mechanisms of the MTAs, we elected to receive a price based on the market gold spot price at the time of delivery adjusted based on the difference between the spot price and the contract price at the time of such election.
Key Aspects of Corporate Gold Sales Contracts

(as of December 31, 2005) |  |
Current termination date of contracts. |  | 2015 in most cases.
Average estimated realizable selling price in 2015. |  | $458/oz.1

Floating Spot-Price Gold Sales Contracts. |  | ($89) million.2

1. |  | Approximate estimated value based on current market US dollar interest rates and an average lease rate assumption of 0.75%. Accelerating gold deliveries would likely lead to reduced contango that would otherwise have built up over time. Barrick may choose to settle any gold sales contract in advance of this termination date at any time, at its discretion. Historically, delivery has occurred in advance of the contractual termination date.
2. |  | At a spot gold price of $513 per ounce, and market interest rates.

In January 2006, we acquired the Pueblo Viejo development project (“Pueblo Viejo”) as part of the Placer Dome acquisition. Once the sale of certain Placer Dome operations to Goldcorp closes, we will have a 60% interest in the project. In anticipation of financing our share of this project, subsequent to year end we allocated 3.0 million ounces of our Corporate Gold Sales Contracts to this project. This allocation does not impact any of the 40% interest in Pueblo Viejo to be owned by Goldcorp.
We have an obligation to deliver gold by the termination date (currently 2015 in most cases). However, because we typically fix the price of gold under our gold sales contracts to a date that is earlier than the termination date of the contract (referred to as the “interim price-setting date”), the actual realized price on the contract termination date depends upon the actual gold market forward premium (“contango”) between the interim price-setting date and the termination date. Therefore, the $458/oz price estimate could change over time due to a number of factors, including but not limited to: US dollar interest rates, gold lease rates, spot gold prices, and extensions of the termination date. This price, which is an average for the total Corporate Gold Sales Contract position, is not necessarily representative of the prices that may be realized each quarter for actual deliveries into gold sales contracts, in particular, if we choose to settle any gold sales contract in advance of the termination date (which we have the right to do at our discretion). If we choose to accelerate gold deliveries, this would likely lead to reduced contango that would otherwise have built up over time (and therefore a lower realized price).
The gold market forward premium, or contango, is typically closely correlated with the difference between US dollar interest rates and gold lease rates. An increase or decrease in US dollar interest rates would generally lead to a corresponding increase or decrease in contango, and therefore an increase or decrease in the estimated future price of the contract at the termination date. Furthermore, the greater the time period between the interim price-setting date and the termination date, the greater the sensitivity of the final realized price to US dollar interest rates.
A short-term spike in gold lease rates would not have a material negative impact on us because we are not significantly exposed under our fixed-price gold sales contracts to short-term gold lease rate variations. A prolonged rise in gold lease rates could result in lower contango (or negative contango, i.e. “backwardation”). Gold lease rates have historically tended to be low, and any spikes short-lived, because of the large amount of gold available for lending relative to demand.
As a result of the Placer Dome acquisition, Barrick’s gold sales contracts increased to 20 million ounces on a pro forma basis as at December 31, 2005. Since year end, Placer Dome’s gold hedge program has been reduced and simplified with all outstanding sold call options eliminated. As of February 22, 2006, the combined gold sales contracts totaled 18.5 million ounces, a reduction of 1.5 million ounces since year-end 2005. Of this total, 9.5 million ounces are allocated as Project Gold Sales Contracts in support of the Pascua-Lama and Pueblo Viejo development projects. The remaining 9.0 million ounces of Corporate Gold Sales Contracts represent 8% of total reserves excluding Pascua-Lama and Pueblo Viejo. Further reductions may be expected as we remain committed to reducing our gold sales contracts in this favorable gold price environment.

We also have floating spot-price silver sales contracts under which we are committed to deliver 7.5 million ounces of silver over the next ten years at spot prices, less an average fixed-price adjustment of $1.25 per ounce. These floating spot-price contracts were previously fixed-price contracts, for which, under the price-setting mechanisms of the MTAs, we elected to receive a price based on the market silver spot price at the time of delivery adjusted by the difference between the spot price and the contract price at the time of such election.
Key Terms of Gold and Silver Sales Contracts
In all of our MTAs, which govern the terms of gold and silver sales contracts with our 19 counterparties, the following applies:

n |  | The counterparties do not have unilateral and discretionary “right to break” provisions.
n |  | There are no credit downgrade provisions.
n |  | We are not subject to any margin calls — regardless of the price of gold or silver.
n |  | We have the right to settle our gold and silver sales contracts on two days notice at any time during the life of the contracts, or keep these forward gold and silver sales contracts outstanding for up to 15 years.
n |  | At our option, we can sell gold or silver at the market price or the contract price, whichever is higher, up to the termination date of the contracts (currently 2015 in most cases).

The MTAs with our counterparties do provide for early close out of certain transactions in the event of a material adverse change in our ability or our principal hedging subsidiary’s ability to perform our or its gold and silver delivery and other obligations under the trading agreements and related parent guarantees or a lack of gold or silver market, and for customary events of default such as covenant breaches, insolvency or bankruptcy. The principal financial covenants are:

n |  | We must maintain a minimum consolidated net worth of at least $2 billion; it was $3.9 billion at year end. The MTAs exclude unrealized mark-to-market valuations in the calculation of consolidated net worth.
n |  | We must maintain a maximum long-term debt to consolidated net worth ratio of 2:1; it was 0.5:1 at year end.

In most cases, under the terms of the MTAs, the period over which we are required to deliver gold is extended annually by one year, or kept “evergreen”, regardless of the intended delivery dates, unless otherwise notified by the counterparty. This means that, with each year that passes, the termination date of most MTAs is extended into the future by one year.
As spot gold prices increase or decrease, the value of our gold mineral reserves and amount of potential operating cash inflows generally increases or decreases. The unrealized mark-to-market loss on our fixed-price forward gold sales contracts also increases or decreases. The mark-to-market value represents the cancellation value of these contracts based on current market levels, and does not represent an immediate economic obligation for payment by us. Our obligations under the gold forward sales contracts are to deliver an agreed upon quantity of gold at a contracted price by the termination date of the contracts (currently 2015 in most cases). Gold sales contracts are not recorded on our balance sheet. The economic impact of these contracts is reflected in our Financial Statements within gold sales based on selling prices under the contracts at the time we record revenue from the physical delivery of gold and silver under the contracts.

Critical Accounting Policies and Estimates
Management has discussed the development and selection of our critical accounting estimates with the Audit Committee of the Board of Directors, and the Audit Committee has reviewed the disclosure relating to such estimates in conjunction with its review of this MD&A. The accounting policies and methods we utilize determine how we report our financial condition and results of operations, and they may require management to make estimates or rely on assumptions about matters that are inherently uncertain.
Our financial condition and results of operations are reported using accounting policies and methods prescribed by US GAAP. In certain cases, US GAAP allows accounting policies and methods to be selected from two or more alternatives, any of which might be reasonable yet result in our reporting materially different amounts. We exercise judgment in selecting and applying our accounting policies and methods to ensure that, while US GAAP compliant, they reflect our judgment of an appropriate manner in which to record and report our financial condition and results of operations.
Accounting Policy Changes in 2005
This section includes a discussion of accounting changes that were adopted in our 2005 Financial Statements.
Emerging Issues Task Force Issue No. 04-6, Accounting for Stripping Costs Incurred During Production in the Mining Industry (“EITF 04-6”)
In 2005, we adopted EITF 04-6, which relates to the accounting for stripping costs in the production stage at a mine. The new accounting rules require the actual stripping costs incurred each period be reflected in the cost of ore mined for the same period, and will likely lead to greater period-to-period volatility in total cash costs. Previously, stripping costs were deferred and amortized based on a life-of-mine stripping ratio that smoothed the costs over time. Results for periods prior to 2005 were not restated in accordance with the transition rules of EITF 04-6. Cost of sales and related total cash costs per ounce statistics for 2004 and prior periods have not been restated, and are therefore not comparable to current-year amounts. The impact of this change in comparison to 2004 was to increase net income for 2005 by $44 million ($0.08 per share) and decrease cost of sales for 2005 by $64 million ($12 per ounce lower total cash costs). Results for 2005 also include a $6 million post-tax credit ($0.01 per share) to reflect the cumulative effect of the policy for periods prior to January 1, 2005.

Future Accounting Policy Changes
This section includes a discussion of future accounting changes that may have a significant impact on our Financial Statements. On January 1, 2006, we adopted FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations (“FIN 47”) and FASB No. 151, Inventory Costs (“FAS 151”). We do not expect that the adoption of FIN 47 or FAS 151 will have a material effect on our Financial Statements, and therefore a detailed discussion of these accounting changes has not been included.
FAS 123R, Share-Based Payment, a Revision to FAS 123 and a Replacement of APB 25 and FAS 148
FAS 123R includes in its scope our stock options, Restricted Share Units (RSUs) and Deferred Share Units (DSUs). The adoption of FAS 123R will not significantly change how we account for RSUs and DSUs. Historically we accounted for stock options granted to employees using an intrinsic value method. We recorded compensation cost for stock options based on the excess of the market price of the stock option at the grant date of an award

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 65

#####

over the exercise price. Historically, the exercise price for stock options has equaled the market price of stock at the grant date, resulting in no compensation cost. FAS 123R requires the cost of all share-based payment transactions with employees be recognized as an expense starting in our 2006 fiscal year.
FAS 123R permits two possible transition methods: modified prospective or modified retrospective. Under both methods the cost of share-based payments will be recorded in 2006, but the modified retrospective method requires restatement of prior year comparative amounts, whereas the modified prospective method does not. Under either method, we expect to record an expense of about $25 million in 2006 for unvested stock options granted through December 31, 2005. Under the modified retrospective method we would restate our income statement for prior periods to reflect a compensation expense of $29 million in 2004 and $26 million in 2005 and an adjustment to opening 2004 retained earnings of $183 million for years prior to 2004.
Exposure Draft, Accounting for Uncertain Tax Positions
On July 14, 2005, the Financial Accounting Standards Board (“FASB”) issued an exposure draft and later issued some amendments of a proposed Interpretation, Accounting for Uncertain Tax Positions – an Interpretation of FASB Statement No. 109. The proposed Interpretation would require companies to recognize the best estimate of an uncertain tax position only if it is more likely than not of being sustained on audit by the taxation authorities. Subsequently, the tax benefit would be derecognized (by either recording a tax liability or decreasing a tax asset) when the more likely than not threshold is no longer met and it is more likely than not that the tax position will not be sustained.
The proposed interpretation would be effective starting in 2007 and treated as a change in accounting policy. It would require companies to assess all uncertain tax positions and only those meeting the more likely than not threshold at the transition date would continue to be recognized. The difference between the amount previously recognized and the amount recognized after applying the proposed Interpretation would be recorded as a cumulative-effect adjustment in the 2007 income statement (restatement is not permitted). The comment period ended on September 12, 2005. Subsequent to this date FASB has issued and continues to issue redeliberations of certain aspects of the exposure draft. We are presently evaluating the impact of this exposure draft on our Financial Statements.
Critical Accounting Estimates and Judgments
Certain accounting estimates have been identified as being “critical” to the presentation of our financial condition and results of operations because they require us to make subjective and/or complex judgments about matters that are inherently uncertain; where there is a reasonable likelihood that materially different amounts could be reported under different conditions or using different assumptions and estimates.
Reserve Estimates Used to Measure Amortization of Property, Plant and Equipment
We record amortization expense based on the estimated useful economic lives of long-lived assets. Changes in reserve estimates are generally calculated at the end of each year and cause amortization expense to increase or decrease prospectively. The estimate that most significantly affects the measurement of amortization is quantities of proven and probable gold reserves, because we amortize a large portion of property, plant and equipment using the units-of-production method. The estimation of quantities of gold reserves, in accordance with the principles in Industry Guide No. 7, issued by the US Securities and Exchange Commission (“SEC”) is complex, requiring significant subjective assumptions that arise from the evaluation of geological, geophysical, engineering and economic data for a given ore body. This data could change over time as a result of numerous factors, including new information gained from development activities, evolving production history and a reassessment of the viability of production under different economic conditions. Changes in data and/or assumptions could cause reserve estimates to substantially change from period to period. Actual gold production could differ from expected gold production based on reserves, and an adverse change in gold or silver prices could make a reserve uneconomic to mine. Variations could also occur in actual ore grade and gold and silver recovery rates from estimates.

66 n Management’s Discussion and Analysis |  | Barrick Annual Report 2005

#####

A key trend that could reasonably impact reserve estimates is rising market gold prices, because the gold price assumption is closely related to the trailing three-year average market price. As this assumption rises, this could result in an upward revision to reserve estimates as material not previously classified as a reserve becomes economic at higher gold prices. Following the recent trend in market gold prices over the last three years, the gold price assumption used to measure reserves has also been rising. The gold price assumption was $400 per ounce in 2005 (2004: $375 per ounce; 2003: $325 per ounce).
The impact of a change in reserve estimates is generally more significant for mines near the end of the mine life because the overall impact on amortization is spread over a shorter time period. Also, amortization expense is more significantly impacted by changes in reserve estimates at underground mines than open-pit mines due to the following factors:

n |  | Underground development costs incurred to access ore at underground mines are significant and amortized using the units-of-production method; and
n |  | Reserves at underground mines are often more sensitive to gold price assumptions and changes in production costs. Production costs at underground mines are impacted by factors such as dilution, which can significantly impact mining and processing costs per ounce.

Impairment Assessments of Investments
Each reporting period we review all available-for-sale securities whose fair value at the end of period is below cost to determine whether an other-than-temporary impairment has occurred. We consider all relevant facts or circumstances in this assessment, particularly: the length of time and extent to which fair value has been less than the carrying amount; the financial condition and near term prospects of the investee, including any specific events that have impacted its fair value; both positive and negative evidence that the carrying amount is recoverable within a reasonable period of time; and our ability and intent to hold the investment for a reasonable period of time sufficient for an expected recovery of the fair value up to or beyond the carrying amount. Changes in the values of these investments are caused by market factors beyond our control and could be significant, and the amount of any impairment charges could materially impact earnings. In 2005, we reviewed two investments that were impaired, and after concluding that the impairments were other-than-temporary, we recorded an impairment charge of $16 million (2004: $5 million, 2003: $11 million).

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 67

#####

Impairment Assessments of Operating Mines, Development Projects and Exploration Stage Properties
We review and test the carrying amounts of assets when events or changes in circumstances suggest that the carrying amount may not be recoverable. We group assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. We review each mine and development project for recoverability by comparing the total carrying value of the assets of that mine or project to the expected future cash flows associated with that mine or project. If there are indications that an impairment may have occurred, we prepare estimates of expected future cash flows for each group of assets. Expected future cash flows are based on a probability-weighted approach applied to potential outcomes. Estimates of expected future cash flow reflect:

n |  | Estimated sales proceeds from the production and sale of recoverable ounces of gold contained in proven and probable reserves;
n |  | Expected future commodity prices and currency exchange rates (considering historical and current prices, price trends and related factors);
n |  | Expected future operating costs and capital expenditures to produce proven and probable gold reserves based on mine plans that assume current plant capacity, but exclude the impact of inflation;
n |  | Expected cash flows associated with value beyond proven and probable reserves, which includes the expected cash outflows required to develop and extract the value beyond proven and probable reserves; and
n |  | Environmental remediation costs excluded from the measurement of asset retirement obligations.

We record a reduction of a group of assets to fair value as a charge to earnings if the discounted expected future cash flows are less than the carrying amount. We generally estimate fair value by discounting the expected future cash flows using a discount factor that reflects the risk-free rate of interest for a term consistent with the period of expected cash flows.
Expected future cash flows are inherently uncertain and could materially change over time. They are significantly affected by reserve estimates, together with economic factors such as gold and silver prices, other commodity and consumables costs and currency exchange rates, estimates of costs to produce reserves and future sustaining capital. If a significant adverse change in the market gold price occurred that caused us to revise the price assumptions downwards, the conclusions on the impairment tests could change, subject to the effect of changes in other factors and assumptions. The assessment and measurement of impairment excludes the impact of derivatives designated in a cash flow hedge relationship for future cash flows arising from operating mines and development projects.
Because of the significant capital investment that is required at many mines, if an impairment occurs, it could materially impact earnings. Due to the long-life nature of many mines, the difference between total estimated undiscounted net cash flows and fair value can be substantial. Therefore, although the value of a mine may decline gradually over multiple reporting periods, the application of impairment accounting rules could lead to recognition of the full amount of the decline in value in one period. Due to the highly uncertain nature of future cash flows, the determination of when to record an impairment charge can be very subjective. We make this determination using available evidence taking into account current expectations for each mining property.
For acquired exploration-stage properties, the purchase price is capitalized, but post-acquisition exploration expenditures are expensed. The future economic viability of exploration-stage properties largely depends upon the outcome of exploration activity, which can take a number of years to complete for large properties. We monitor the results of exploration activity over time to assess whether an impairment may have occurred. The measurement of any impairment is made more difficult because there is not an active market for exploration properties, and because it is not possible to use discounted cash flow techniques due to the very limited information that is available to accurately model future

68 n Management’s Discussion and Analysis |  | Barrick Annual Report 2005

#####

cash flows. In general, if an impairment occurs at an exploration-stage property, it would probably have minimal value and most of the acquisition cost may have to be written down. Impairment charges are recorded in other income/expense and impact earnings in the year they are recorded. Prospectively, the impairment could also impact the calculation of amortization of an asset.
In 2004, we completed impairment tests for the Cowal project, the Eskay Creek mine and various Peruvian exploration-stage properties. For Cowal, an impairment test was completed, incorporating upward revisions to estimated capital and operating costs for the project and the impact of the US dollar exchange rate on Australian dollar expenditures, measured at market prices. On completion of this test in 2004, we concluded that the project was not impaired. On completion of the impairment test for Eskay Creek, we concluded that the mine was impaired, and we recorded a pre-tax impairment charge of $58 million. On completion of the exploration program for 2005 and updating assessments of future plans, we concluded that a group of Peru-vian exploration-stage properties were impaired at the end of 2004 and we recorded a pre-tax impairment charge of $67 million. Throughout 2005, we updated our impairment assessments for the Eskay Creek mine and Cowal project and we concluded that they were not impaired at the end of 2005.
Production Start Date
We assess each mine construction project to determine when a mine moves into production stage. The criteria used to assess the start date are determined based on the unique nature of each mine construction project such as the complexity of a plant or its location. We consider various relevant criteria to assess when the mine is substantially complete and ready for its intended use and moved into production stage. Some of the criteria considered would include, but, are not limited to, the following:

n |  | The level of capital expenditures compared to construction cost estimates
n |  | Completion of a reasonable period of testing of mine plant and equipment
n |  | Ability to produce gold in saleable form (within specifications)
n |  | Ability to sustain ongoing production of gold

In 2005, we determined the production start dates for three new mines: Tulawaka, Lagunas Norte and Veladero. When a mine construction project moves into the production stage, the capitalization of certain mine construction costs ceases and costs are either capitalized to inventory or expensed, except for capitalizable costs related to property, plant and equipment additions or improvements, underground mine development or reserve development.
Fair Value of Asset Retirement Obligations (AROs)
AROs arise from the acquisition, development, construction and normal operation of mining property, plant and equipment, due to government controls and regulations that protect the environment and public safety on the closure and reclamation of mining properties. We record the fair value of an ARO in our Financial Statements when it is incurred and capitalize this amount as an increase in the carrying amount of the related asset. At operating mines, the increase in an ARO is recorded as an adjustment to the corresponding asset carrying amount and results in a prospective increase in amortization expense. At closed mines, any adjustment to an ARO is charged directly to earnings.
The fair values of AROs are measured by discounting the expected cash flows using a discount factor that reflects the credit-adjusted risk-free rate of interest. We prepare estimates of the timing and amounts of expected cash flows when an ARO is incurred, which are updated to reflect changes in facts and circumstances, or if we are required to submit updated mine closure plans to regulatory authorities. In the future, changes in regulations or laws or enforcement could adversely affect our operations; and any instances of noncompliance with laws or regulations that result in fines or injunctions or delays in projects, or any unforeseen environmental contamination at, or related to, our mining properties could result in us suffering significant costs. We mitigate these risks through environmental

Barrick Annual Report 2005 |  | Management’s Discussion and Analysis n 69

#####

and health and safety programs under which we monitor compliance with laws and regulations and take steps to reduce the risk of environmental contamination occurring. We maintain insurance for some environmental risks, however, for some risks coverage cannot be purchased at a reasonable cost. Our coverage may not provide full recovery for all possible causes of loss. The principal factors that can cause expected cash flows to change are: the construction of new processing facilities; changes in the quantities of material in reserves and a corresponding change in the life of mine plan; changing ore characteristics that ultimately impact the environment; changes in water quality that impact the extent of water treatment required; and changes in laws and regulations governing the protection of the environment. In general, as the end of the mine life becomes nearer, the reliability of expected cash flows increases, but earlier in the mine life, the estimation of an ARO is inherently more subjective. Significant judgments and estimates are made when estimating the fair value of AROs. Expected cash flows relating to AROs could occur over periods up to 40 years and the assessment of the extent of environmental remediation work is highly subjective. Considering all of these factors that go into the determination of an ARO, the fair value of AROs can materially change over time.
At our operating mines, we continued to record AROs based on disturbance of the environment over time. It is reasonably possible that circumstances could arise during or by the end of the mine life that will require material revisions to AROs. In particular, the extent of water treatment can have a material effect on the fair value of AROs, and the expected water quality at the end of the mine life, which is the primary driver of the extent of water treatment, can change significantly. We periodically prepare updated studies for our mines, following which it may be necessary to adjust the fair value of AROs. The period of time over which we have assumed that water quality monitoring and treatment will be required has a significant impact on AROs at closed mines. The amount of AROs recorded reflects the expected cost, taking into account the probability of particular scenarios. The difference between the upper end of the range of these assumptions and the lower end of the range can be significant, and consequently changes in these assumptions could have a material effect on the fair value of AROs and future earnings in a period of change.
At one closed mine, the principal uncertainty that could impact the fair value of the ARO is the manner in which a tailings facility will need to be remediated. In measuring the ARO, we have concluded that there are two possible methods that could be used. We have recorded the ARO using the more costly method until such time that the less costly method can be proven as technically feasible and approved.
In 2005, we recorded increases in ARO estimates of $91 million (2004: $68 million; 2003: $10 million) of which $47 million of this increase (2004: $14 million; 2003: nil) related to new AROs at development projects and mines that commenced production during 2005. A further $29 million (2004: $32 million; 2003: nil) relates to updates of the assessment of the extent of water treatment and other assumptions at our operating mines. We recorded increases in AROs of $15 million at our closed mines, which were charged to earnings (2004: $22 million; 2003: $10 million).

Deferred Tax Assets and Liabilities
Measurement of Temporary Differences
We are periodically required to estimate the tax basis of assets and liabilities. Where applicable tax laws and regulations are either unclear or subject to varying interpretations, it is possible that changes in these estimates could occur that materially affect the amounts of deferred income tax assets and liabilities recorded in our Financial Statements. Changes in deferred tax assets and liabilities generally have a direct impact on earnings in the period of changes. The most significant such estimate is the tax basis of certain Australian assets following elections in 2004 under new tax regimes in Australia. These elections resulted in the revaluation of certain assets in Australia for income tax purposes. Part of the revalued tax basis of these assets was estimated based on a valuation completed for tax purposes. This valuation is under review by the Australian Tax Office (“ATO”) and the amount finally accepted by the ATO may differ from the assumption used to measure deferred tax balances at the end of 2004.
Valuation Allowances
Each period, we evaluate the likelihood of whether some portion or all of each deferred tax asset will not be realized. This evaluation is based on historic and future expected levels of taxable income, the pattern and timing of reversals of taxable temporary timing differences that give rise to deferred tax liabilities, and tax planning initiatives. Levels of future taxable income are affected by, among other things, market gold prices, production costs, quantities of proven and probable gold reserves, interest rates and foreign currency exchange rates. If we determine that it is more likely than not (a likelihood of more than 50%) that all or some portion of a deferred tax asset will not be realized, then we record a valuation allowance against the amount we do not expect to realize. Changes in valuation allowances are recorded as a component of income tax expense or recovery for each period. The most significant recent trend impacting expected levels of future taxable and valuation allowances has been rising gold prices. A continuation of this trend could lead to the release of some of the valuation allowances recorded, with a corresponding effect on earnings in the period of release.
In 2005, we released valuation allowances totaling $32 million, which mainly included amounts totaling $31 million in Argentina, relating to the effect of the higher gold price environment and start-up of production at Veladero in 2005. We released valuation allowances totaling $5 million in 2004 and $62 million in 2003. In 2004, the release was as a consequence of an election to consolidate our Australian operations into one tax group. Valuation allowances released in 2003 mainly included: $21 million in North America following a corporate reorganization of certain subsidiaries that enabled us to utilize certain previously unrecognized tax assets; $16 million in Australia realized in 2003 due to an increase in taxable income from higher gold prices; and $15 million in Argentina after the approval to begin construction of our new Veladero mine and classification of mineralization as a proven and probable reserve.
The Placer Dome acquisition may cause us to reconsider that some of our deferred tax assets, to which valuation allowances have been applied, are now more likely than not to be realized. If we determine that, as a direct result of the Placer Dome acquisition, some or all of the valuation allowances can be released, any amounts that we release may be reflected as an adjustment to goodwill in the purchase price allocation.

United States: most of the valuation allowances relate to the full amount of Alternative Minimum Tax credits, which have an unlimited carry-forward period. Increasing levels of future taxable income due to higher gold selling prices and other factors and circumstances may result in our becoming a regular taxpayer under the US regime, which may cause us to release some, or all, of the valuation allowance on the Alternative Minimum Tax credits.
Chile and Argentina: the valuation allowances relate to the full amount of tax assets in subsidiaries that do not have any present sources of gold production or taxable income. In the event that these subsidiaries have sources of taxable income in the future, we may release some or all of the allowances.
Canada: substantially all of the valuation allowances relate to capital losses that will only be utilized if any capital gains are realized.
Tanzania: considering the local fiscal regime applicable to mining companies and expected levels of future taxable income from the Bulyanhulu and Tulawaka mines, a valuation allowance exists against a portion of the deferred tax assets. If we conclude that expected levels of future taxable income from Bulyanhulu and Tulawaka will be higher, we may release some or all of the valuation allowance.
Stock-Based Compensation
We calculate and disclose in our Financial Statements pro forma compensation expense for employee stock options. Commencing in first quarter 2006, we will record compensation expense in earnings for employee stock options, based on the estimated fair market value of employee stock options on their grant date. The most significant assumptions involving judgment that affect a stock option’s fair value include, but are not limited to: expected volatility, expected term and expected exercise behavior of option holders.
We determine expected future volatility by taking into consideration both historical volatility of our US dollar share price and the implied volatility of our US dollar market traded stock options. Under the Black-Scholes valuation model, the term assumption takes into consideration expected rates of employee turnover and represents the estimated average length of time stock options remain outstanding before they are either exercised or forfeited. Under the Lattice valuation model, the expected term assumption is derived from the option valuation model and is in part based on expected exercise behavior of option holders based on multiple share price paths. When reviewing the historical behavior of option holders, we segregate the population into groups with similar characteristics.
Stock option expense is impacted by estimated forfeiture rates for stock options. We estimate forfeiture rates by considering trends in historical forfeiture rates. If actual forfeiture rates differ from estimated rates, we adjust our stock option expense to reflect revised expectations. For assumptions used in stock option valuation, we apply any updated assumptions to the valuation of future grants. Our option fair value has changed at each grant date as we update our historical data used to calculate specific assumptions, namely; the expected volatility and expected term of the option. With each grant date, we incorporate the current market stock price and interest rates into our valuation model, both of these assumptions change on an ongoing basis.

Cautionary Statement on Forward-Looking Information
Certain information contained or incorporated by reference in this Annual Report 2005, including any information as to our future financial or operating performance, constitutes “forward-looking statements”. All statements, other than statements of historical fact, are forward-looking statements. The words “believe”, “expect”, “anticipate”, “contemplate”, “target”, “plan”, “intends”, “continue”, “budget”, “estimate”, “may”, “will”, “schedule” and similar expressions identify forward-looking statements. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by us, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements. Such factors include, but are not limited to: fluctuations in the currency markets (such as the Canadian and Australian dollars versus the US dollar); fluctuations in the spot and forward price of gold or certain other commodities (such as silver, copper, diesel fuel and electricity); changes in US dollar interest rates or gold lease rates that could impact the mark-to-market value of outstanding derivative instruments and ongoing payments/receipts under interest rate swaps and variable rate debt obligations; risks arising from holding derivative instruments (such as credit risk, market liquidity risk and mark-to-market risk); changes in national and local government legislation, taxation, controls, regulations and political or economic developments in Canada, the United States, Dominican Republic, Australia, Papua New Guinea, Chile, Peru, Argentina, South Africa, Tanzania, Russia or Barbados or other countries in which we do or may carry on business in the future; business opportunities that may be presented to, or pursued by, us; our ability to successfully integrate acquisitions, including our recent acquisition of Placer Dome; operating or technical difficulties in connection with mining or development activities; the speculative nature of gold exploration and development, including the risks of obtaining necessary licenses and permits; diminishing quantities or grades of reserves; adverse changes in our credit rating; and contests over title to properties, particularly title to undeveloped properties. In addition, there are risks and hazards associated with the business of gold exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance, or inability to obtain insurance, to cover these risks). Many of these uncertainties and contingencies can affect our actual results and could cause actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, us. Readers are cautioned that forward-looking statements are not guarantees of future performance. All of the forward-looking statements made in this Annual Report 2005 are qualified by these cautionary statements. Specific reference is made to Barrick’s most recent Form 40-F/Annual Information Form on file with the SEC and Canadian provincial securities regulatory authorities for a discussion of some of the factors underlying forward-looking statements.
We disclaim any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise, except to the extent required by applicable laws.

Notes to Consolidated Financial Statements
Barrick Gold Corporation. Tabular dollar amounts in millions of United States dollars, unless otherwise shown. References to C$, A$, € and ARS are to Canadian dollars, Australian dollars, Euros, and Argentinean pesos, respectively.
1 n Nature of Operations
Barrick Gold Corporation (“Barrick” or the “Company”) engages in the production and sale of gold from underground and open-pit mines, including related activities such as exploration and mine development. Our operations are mainly located in North America, South America, Australia, Africa and Russia/Central Asia. Our gold is sold into the world market.
2 n Significant Accounting Policies
a) Basis of Preparation
These financial statements have been prepared under United States generally accepted accounting principles (“US GAAP”). To ensure comparability of financial information, certain prior-year amounts have been reclassified to conform with the current year presentation.
b) Consolidation
These financial statements reflect consolidation of entities in which we have a controlling financial interest. The usual condition for a controlling financial interest is ownership of a majority of the voting interests of an entity. A controlling financial interest may also exist through arrangements that do not involve voting interests, where an entity is a variable interest entity (“VIE”). Intercompany balances and transactions are eliminated on consolidation.
A VIE is an entity that either lacks enough equity investment at risk to permit the entity to finance its activities without additional subordinated financial support from other parties; has equity owners who are unable to make decisions about the entity; or has equity owners that do not have the obligation to absorb the entity’s expected losses or the right to receive the entity’s expected residual returns. VIEs can arise from a variety of contractual arrangements or other legal structures.
Where a VIE exists, the variable interest holder who is the primary beneficiary consolidates the VIE. The primary beneficiary is the entity that, after evaluating all expected transactions between the VIE and the variable interest holders, expects to absorb a majority of the expected losses of the VIE, receive a majority of the residual returns of the VIE, or both.
We hold a 70% interest in an unincorporated joint venture that owns the Tulawaka mine. This joint venture was originally formed to share in the risks and rewards of exploring for gold and developing any mines on a significant land position in Tanzania. Until June 2004, we used the proportionate consolidation method for our 70% joint venture interest. In June 2004, upon entering into an agreement to finance the other joint venture partner’s share of mine construction costs, we concluded that the joint venture had become a VIE and that we are the primary beneficiary. From June 2004 onwards, we began consolidating 100% of the joint venture, recording a non-controlling interest for the interest held by the other joint venture partner. The carrying value of assets that are collateral for the VIEs obligations are property, plant and equipment of $63 million and working capital of $24 million. The creditors of the joint venture have recourse only to the assets of the joint venture and not to any other assets of Barrick.
We hold our interests in the Round Mountain, Hemlo, Marigold and Kalgoorlie mines through unincorporated joint ventures under which we share joint control of operating, investing and financing decisions with the other joint venture partners. We use the proportionate consolidation method to account for our interests in these unincorporated joint ventures. For further information refer to note 25.

c) Foreign Currency Translation
The functional currency of all our operations is the US dollar. We translate non-US dollar balances into US dollars as follows:

n |  | non-monetary assets and liabilities using historical rates;
n |  | monetary assets and liabilities using closing rates with translation gains and losses recorded in earnings; and
n |  | income and expenses using average exchange rates, except for expenses that relate to non-monetary assets and liabilities measured at historical rates.

d) Use of Estimates
The preparation of these financial statements requires us to make estimates and assumptions. The most significant ones are: quantities of proven and probable gold reserves; the value of mineralized material beyond proven and probable reserves; future costs and expenses to produce proven and probable reserves; future commodity prices and foreign currency exchange rates; the future cost of asset retirement obligations; the amounts of contingencies; and assumptions used in the accounting for employee stock options such as volatility, expected term and forfeiture rates for unvested options. Using these estimates and assumptions, we make various decisions in preparing the financial statements including:

n |  | the treatment of mine development costs as either an asset or an expense;
n |  | whether long-lived assets are impaired, and if so, estimates of the fair value of those assets and any corresponding impairment charge;
n |  | our ability to realize deferred income tax assets;
n |  | the useful lives of long-lived assets and the measurement of amortization;
n |  | the fair value of asset retirement obligations;
n |  | the likelihood of loss contingencies occurring and the amount of any potential loss;
n |  | whether investments are impaired; and
n |  | the amount of stock option expense included in pro forma stock option disclosures.

As the estimation process is inherently uncertain, actual future outcomes could differ from present estimates and assumptions, potentially having material future effects on our financial statements.

Total |  | $ | 6 |  |  | $ | — |  |  | $ | (17 | )

1. |  | On adoption of FAS 143 on January 1, 2003, we recorded an increase in property, plant and equipment of $39 million; an increase in other long-term obligations of $32 million; and an increase in deferred income tax liabilities of $3 million; as well as a $4 million credit in earnings for the cumulative effect of this change.
2. |  | On January 1, 2003, we changed our accounting policy for amortization of underground mine development costs to exclude estimates of future underground development costs. On January 1, 2003, we recorded a decrease in property, plant and equipment of $19 million; an increase in deferred income tax liabilities of $2 million; and a $21 million charge to earnings for the cumulative effect of this change.
3. |  | In second quarter 2005, we adopted EITF 04-6 and changed our accounting policy for stripping costs incurred in the production phase. Prior to adopting EITF 04-6, we capitalized stripping costs incurred in the production phase, and we recorded amortization of the capitalized costs as a component of the cost of inventory produced each period. Under EITF 04-6, stripping costs are recorded directly as a component of the cost of inventory produced each period. Using an effective date of adoption of January 1, 2005, we recorded a decrease in capitalized mining costs of $226 million; an increase in the cost of inventory of $232 million; and a $6 million credit to earnings for the cumulative effect of this change. For the year ended December 31, 2005, the effect of adopting EITF 04-6 compared to the prior policy was an increase in net income of $44 million ($0.08 per share), excluding the cumulative effect on prior periods.

FSP FAS 115-1 and FAS 124-1, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments
FSP FAS 115-1 and FAS 124-1 was issued in November 2005 to provide further guidance to determine when an investment is considered impaired, whether the impairment is other than temporary, and the measurement of an impairment loss. We prospectively adopted this FSP in fourth quarter 2005. Our accounting policy for assessing the impairment of investments is described in note 11. The adoption of FSP FAS 115-1 and FAS 124-1 in 2005 had no effect on our financial statements.

FIN 47, Accounting for Conditional Asset Retirement Obligations (AROs)
FIN 47 was issued in March 2005 and is effective for our 2005 fiscal year. It relates to the accounting for a legal obligation to perform an asset retirement activity, when the timing or method of settlement is conditional on a future event, which may not be within our control. Under FIN 47, a liability for the fair value of a conditional ARO is recorded if the fair value can be reasonably estimated. FIN 47 was issued because of diversity in practice in applying FAS 143. Some entities recorded AROs prior to the retirement of an asset, while other entities recorded the ARO only when it was either probable that the asset would be retired or when the asset was actually retired. The adoption of FIN 47 in 2005 had no significant effect on the amount of AROs recorded in our financial statements.
f) Accounting Developments
FAS 123R, Accounting for Stock-Based Compensation
FAS 123R is applicable to transactions in which an entity exchanges its equity instruments for goods and services. It focuses primarily on transactions in which an entity obtains employee services in share-based payment transactions. The principal reason for issuing FAS 123R was to address concerns of users of financial statements, including institutional and individual investors that using an intrinsic value method results in financial statements that do not faithfully represent the economic effect of the receipt and consumption of employee services in exchange for equity instruments. FAS 123R addresses these concerns by requiring an entity to recognize the cost of employee services received in share-based payment transactions, thereby reflecting the economic consequences of those transactions in the financial statements. A further reason was to improve the comparability of reported financial information by eliminating alternative accounting methods. By requiring the fair-value-based method for all public entities, FAS 123R eliminates an alternative accounting method; consequently, similar economic transactions will be accounted for similarly. FAS 123R requires that the fair value of such equity instruments be recorded as an expense as services are performed. Equity instruments included under the scope of FAS 123R are our stock options, restricted share units (RSUs) and deferred share units (DSUs). Prior to FAS 123R, a company could elect to account for the cost of employee stock options using an intrinsic value approach based on the excess of the market price at the date of grant over the exercise price, and provide pro forma disclosures of the effect of accounting for employee stock options using a fair value approach. The adoption of FAS 123R will not have a significant impact on how we account for RSUs and DSUs. We intend to adopt FAS 123R for our first quarter 2006 financial statements. FAS 123R permits different transition methods including retroactive adjustment of prior periods as far back as 1995 to give effect to the fair-value-based method of accounting for awards granted in those prior periods; or a modified prospective application beginning in 2006. For further information see note 22.
FAS 151, Inventory Costs
FAS 151 specifies the general principles applicable to the pricing and allocation of certain costs to inventory. FAS 151 is the result of a broader effort by the Financial Accounting Standards Board (FASB) to improve the comparability of cross-border financial reporting by working with the International Accounting Standards Board (IASB) toward development of a single set of high-quality accounting standards. As part of that effort, the FASB and the IASB identified opportunities to improve financial reporting by eliminating certain narrow differences between their existing accounting standards. The accounting for inventory costs, in particular, abnormal amounts of idle facility expense, freight, handling costs, and spoilage, is one such narrow difference that the FASB decided to address by issuing FAS 151. As currently worded in ARB 43, Chapter 4, the term “abnormal” was not defined and its application could lead to unnecessary noncomparability of financial reporting. FAS 151 eliminates that term. Under FAS 151, abnormal amounts of idle facility expense, freight, handling costs and wasted materials are recognized as current period charges rather than capitalized to inventory. FAS 151 also requires that the allocation of fixed production overhead to the cost of inventory be based on the normal capacity of production facilities. FAS 151 will be effective beginning in first quarter 2006.

FAS 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FAS 3
FAS 154 relates to the accounting for and reporting of a change in accounting principle and applies to all voluntary changes in accounting principles. The reporting of corrections of an error by restating previously issued financial statements is also addressed by this statement. FAS 154 applies to authoritative pronouncements in the event they do not include specific transition provisions. When an authoritative pronouncement includes specific transition provisions, those provisions should be followed. FAS 154 requires retrospective application to prior periods’ financial statements of changes in accounting principle, unless the period-specific effects or cumulative effects of an accounting change are impracticable to determine, in which case the new accounting principle is required to be applied to the assets and liabilities as of the earliest period practicable, with a corresponding adjustment made to opening retained earnings. Prior to FAS 154, most accounting changes were recorded effective at the beginning of the year of change, with the cumulative effect at the beginning of the year of change recorded as a charge or credit to earnings in the period a change was adopted. FAS 154 will be effective for accounting changes and corrections of errors occurring in 2006 onwards. FAS 154 does not change the transition provisions of any existing accounting pronouncements, including those that are in the transition phase as of the effective date of FAS 154.
Exposure Draft, Accounting for Uncertain Tax Positions
In July 2005, the FASB issued an exposure draft on Accounting for Uncertain Tax Positions — an Interpretation of FASB Statement No. 109. The interpretation has been developed because of diversity in practice for accounting for uncertain tax positions. Some entities record tax benefits for uncertain tax positions as they are filed on the income tax return, while others use either gain contingency accounting or a probability threshold.
The exposure draft requires companies to record the best estimate of the benefits of an uncertain tax position only if it is probable of being sustained on audit by the taxing authority based solely on the technical merits of the position. Under the draft Interpretation, benefits from tax positions that previously failed to meet the recognition threshold would be recognized in any subsequent period in which that threshold is met. Previously recognized tax benefits from positions that no longer meet a more-likely-than-not recognition threshold would be de-recognized by recording an income tax liability or eliminating a deferred tax asset in the period in which it is more likely than not that the tax position will not be sustained. The requirement to assess the need for a valuation allowance for deferred tax assets based on the sufficiency of future taxable income would be unchanged by the final Interpretation. The final Interpretation will also provide guidance on disclosure, accrual of interest and penalties, and accounting in interim periods and transition. In November 2005, the FASB decided to change the initial recognition threshold proposed in the exposure draft from “probable” to “more-likely-than-not”. The FASB expects to issue a final Interpretation in 2006 that would be effective for our fiscal 2007 financial statements. After the final Interpretation is issued, we intend to complete our assessment of the impact on our financial statements.
g) Changes in Estimates
Gold Mineral Reserves
At the end of each fiscal year we update estimates of proven and probable gold mineral reserves at each mineral property. Following the update, we prospectively revise calculations of amortization of property, plant and equipment beginning in the first quarter of the next fiscal year. The effect of changes in reserve estimates at the end of 2004 on amortization expense for the fiscal year ended December 31, 2005 was a decrease of $28 million (2004: $15 million decrease; 2003: $14 million decrease).
Asset Retirement Obligations (AROs)
Each period we update cost estimates for AROs at each of our mineral properties to reflect new events, changes in circumstances and any new information that is available. The changes in these cost estimates generally have a corresponding impact on the fair value of the ARO. For closed mines any change in the fair value of AROs is included as a charge or credit within environmental remediation costs in other expense. An expense of $15 million was recorded in 2005 for changes in cost estimates for AROs at closed mines (2004: $22 million expense; 2003: $10 million expense).
Tax Valuation Allowances
For a description of changes in valuation allowances refer to note 8.

3 n Business Combinations
a) Acquisition of Placer Dome Inc. (“Placer Dome”)
Placer Dome Offer and Acceptance
On October 31, 2005 we announced a proposed acquisition of Placer Dome. In early 2006, we offered to acquire all of the outstanding common shares of Placer Dome for either US$22.50 in cash or 0.8269 of a Barrick common share plus US$0.05 in cash per Placer Dome common share, subject in each case to pro ration of a maximum cash amount of $1,344 million. Funding for the maximum cash amount will be from our $1 billion credit and guarantee agreement, with any excess from our existing cash position. By February 3, 2006, 419 million common shares of Placer Dome had been validly deposited to our offer. We took up and accepted for payment all of such shares, which represented about 94% of the common shares of Placer Dome. For the common shares tendered by February 3, 2006, the aggregate cash consideration was US$1,161 million and the aggregate number of Barrick common shares issued was 304 million shares.
Placer Dome is one of the world’s largest gold mining companies, and produced 3.6 million ounces of gold and 359 million pounds of copper in 2005 (unaudited). It has 12 producing mines based in North America, South America, Africa and Australia/New Guinea, and four projects that are in various stages of exploration/ development. Its most significant mines are Cortez in the United States, Zaldívar in Chile, Porgera in New Guinea, North Mara in Tanzania and South Deep in South Africa. The most significant projects are Cortez Hills and Donlin Creek in the United States, and Pueblo Viejo in the Dominican Republic. We plan to sell Placer Dome’s Canadian mines to Goldcorp Inc. (“Goldcorp”), as well as certain other interests in mineral properties. Placer Dome had a gold hedge position totaling 7.2 million ounces at the date of acquisition. Furthermore, Placer Dome has gold lease rate swaps where the obligation was expressed in ounces. We plan to focus on reducing this acquired hedge position over time, consistent with the plans for our existing gold hedge position.
We believe that the business combination between ourselves and Placer Dome is a unique opportunity to create a Canadian-based leader in the global gold mining industry. This business combination strengthens our position, including in respect of reserves, production, growth opportunities, and balance sheet strength.

Accounting for the Placer Dome Acquisition
The Placer Dome acquisition will be accounted for as a purchase business combination, with Barrick as the accounting acquirer. We secured control of Placer Dome on January 19, 2006, which is the accounting acquisition date with the results of operations of Placer Dome consolidated from January 20, 2006. Assuming 100% of the outstanding common shares of Placer Dome are acquired, the purchase cost is estimated at $10.1 billion, including all the consideration issued in the form of cash, Barrick common shares, and direct costs related to the acquisition.

Value of 322.8 million Barrick common shares at $27.14 per share |  | $ | 8,761 |
Cash |  |  | 1,344 |
Transaction costs |  |  | 25 |
|  | $ | 10,130 |

The measurement of the purchase consideration will be based on a Barrick common share price of $27.14, representing the average closing price on the New York Stock Exchange for the two days prior to and two days after the public announcement of our final offer for Placer Dome.
The purchase cost will be allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. We will determine the estimated fair values based on independent appraisals, discounted cash flows, quoted market prices, and estimates made by management. To the extent that the purchase cost exceeds the fair value of the net identifiable tangible and intangible assets acquired, such excess will be allocated to goodwill. The following table summarizes the current allocation of the Placer Dome purchase cost to assets and liabilities. It reflects only certain limited fair value adjustments for identifiable assets and liabilities acquired, including an adjustment for the fair value of derivatives at acquisition. The purchase price allocation is preliminary and subject to adjustment following completion of the valuation process and analysis of tax effects. The difference between the cost of acquisition and the values of net assets acquired has been presented as “unallocated purchase price”.

1. |  | For the purposes of presenting a summary of assets and liabilities acquired, the balance sheet of Placer Dome at December 31, 2005 has been used as a proxy for the balance sheet on January 19, 2006. We do not expect any material differences between the balance sheet at January 19, 2006 and the balance sheet at December 31, 2005.

b) Sale of Operations to Goldcorp
Goldcorp has agreed, subject to conditions to acquire from us, all of Placer Dome’s Canadian properties and operations (other than Placer Dome’s offices in Vancouver and Toronto), including all mining, reclamation and exploration properties, Placer Dome’s interest in the La Coipa mine in Chile, 40% of Placer Dome’s interest in the Pueblo Viejo project in the Dominican Republic, certain related assets and, at the option of Goldcorp, our share in Agua de la Falda S.A., which includes our interest in the Jeronimo project (collectively, the “Goldcorp Assets’’). Goldcorp will be responsible for all liabilities relating solely to the Goldcorp Assets, including employment commitments and environmental, closure and reclamation liabilities (collectively, the “Goldcorp Liabilities’’).
The estimated sales proceeds from Goldcorp are about $1,500 million, subject to certain adjustments on closing that are defined in the sale agreement. The results of operations will be consolidated into Barrick until the closing of the sale of operations to Goldcorp. On closing of the sale, the assets and liabilities relating to those operations, as well as a portion of the unallocated purchase price will be removed from our balance sheet. We do not expect to record a significant gain or loss on closing of the sale. At December 31, 2005, the carrying amount of assets was about $298 million and liabilities was about $77 million relating to the operations that will be sold to Goldcorp.

Basis of Presentation
This unaudited pro forma consolidated financial statement information has been prepared by us for illustrative purposes only to show the effect of the acquisition of Placer Dome by Barrick. The unaudited pro forma consolidated statement information assumes that Barrick will acquire all of Placer Dome’s outstanding shares and exchange any outstanding Placer Dome stock options for equivalent Barrick stock options. The unaudited pro forma consolidated financial statement information assumes that all in-the-money Placer Dome stock options will be exercised and included in the outstanding Placer Dome shares to be acquired by Barrick. Barrick has entered into an agreement with Goldcorp that will result in the sale of certain operations and projects of Placer Dome, including the Canadian operations, the La Coipa mine and a 40% interest in the Pueblo Viejo project. Barrick will receive about $1,500 million in cash from Goldcorp for the sale of these operations (assuming no adjustments are required). This unaudited pro forma consolidated financial statement information assumes that there will be no tax consequences to Barrick for the sale of these operations to Goldcorp. Pro forma adjustments for the assumed effect of the sale of these operations to Goldcorp on the results of operations of Barrick have been reflected in this unaudited pro forma consolidated financial statement information.
The unaudited pro forma consolidated financial statement information is not intended to be indicative of the results that would actually have occurred, or the results expected in future periods, had the events reflected herein occurred on the dates indicated. Actual amounts recorded upon finalization of purchase price adjustments and subsequent sale of certain Placer Dome operations to Goldcorp will likely differ from those recorded in this unaudited pro forma consolidated financial statement information. Any potential synergies that may be realized and integration costs that may be incurred have been excluded from the unaudited pro forma financial statement information, including Placer Dome transaction costs and amounts payable under change of control agreements to certain members of management that are estimated at a combined total of $93 million. The information prepared is only a summary.
In preparing the unaudited pro forma consolidated financial statement information, an initial review was undertaken to identify Placer Dome accounting policy differences where the impact was potentially material and could be reasonably estimated. Further accounting policy differences may be identified. In particular, we adopted EITF 04-6, Accounting for Stripping Costs Incurred during Production in the Mining Industry, effective January 1, 2005, whereas Placer Dome has not yet adopted EITF 04-6. Estimates concerning the impact of Placer Dome applying EITF 04-6 in the unaudited pro forma consolidated financial statement information have not yet been finalized and no adjustment has been recorded. The effects on the Placer Dome mines of adopting EITF 04-6 could be significant.
The unaudited pro forma consolidated statement of income for the year ended December 31, 2005 has been prepared from the statements of income for each of Barrick and Placer Dome for the period after giving pro forma effect to the acquisition of Placer Dome by Barrick and subsequent sale of certain operations to Goldcorp as if both transactions had occurred on January 1, 2005 based on the assumptions below.
The unaudited pro forma consolidated balance sheet as at December 31, 2005 has been prepared from the consolidated balance sheets of Barrick and Placer Dome as at December 31, 2005, after giving pro forma effect to the acquisition of Placer Dome by Barrick and subsequent sale of certain operations to Goldcorp as if both transactions had occurred on December 31, 2005 based on the assumptions below.
Pro Forma Assumptions and Adjustments
The acquisition of Placer Dome will be accounted for using the purchase method of accounting. Certain adjustments have been reflected in this unaudited pro forma consolidated statement of income to illustrate the effects of purchase accounting and to reflect the impact of the sale of certain Placer Dome operations to Goldcorp, where the impact could be reasonably estimated. In 2006, we will complete an exercise to value the identifiable assets and liabilities acquired, including any goodwill that may arise in the acquisition.
On December 31, 2005, Placer Dome had certain convertible debt and stock options outstanding, which if converted/exercised would result in an increase in Placer Dome common shares outstanding by approximately 22.7 million shares. This unaudited pro forma consolidated financial statement information reflects the issuance by Placer Dome of approximately 10.1 million shares on exercise of in-the-money stock options

of Placer Dome at December 31, 2005, but excludes the impact of 12.6 million potential shares that could theoretically be issued due to the conversion/exercise of Placer Dome’s convertible debt and other stock options.
We have not yet determined the fair value of all identifiable assets and liabilities acquired, the amount of the purchase price that may be allocated to goodwill, or the complete impact of applying purchase accounting on the income statement. Therefore, after reflecting the pro forma purchase adjustments identified to date, the excess of the purchase consideration over the adjusted book values of Placer Dome’s assets and liabilities has been presented as “unallocated purchase price”. In 2006, the fair value of all identifiable assets and liabilities acquired as well as any goodwill arising upon the acquisition will be determined. On completion of valuations, with a corresponding adjustment to the historic carrying amounts of property, plant and equipment, or on recording of any finite life intangible assets on acquisition, these adjustments will impact the measurement of amortization recorded in our consolidated income statement for periods after the date of acquisition. We estimate that a $100 million adjustment to the carrying amount of property, plant and equipment of Placer Dome would result in a corresponding adjustment to amortization expense in the pro forma statement of income by approximately $6 million for the year ended December 31, 2005. No pro forma adjustments have been reflected for any changes in deferred tax assets or liabilities that would result from recording Placer Dome’s identifiable assets and liabilities at fair value as the process of estimating the fair value of identifiable assets and liabilities is not complete.
Pro Forma Adjustments
The unaudited pro forma consolidated statement of income reflects the following adjustments as if the acquisition of 100% of Placer Dome and subsequent sale of certain operations to Goldcorp had occurred on January 1, 2005:

(b) |  | An increase in interest expense by $48 million for the year ended December 31, 2005 to reflect the interest costs (net of amounts that would have been capitalized to Barrick development projects) relating to the cash component of the Offer that will be financed through temporary credit facilities. A decrease in interest expense by $49 million for the year ended December 31, 2005 to reflect the assumed avoidance of interest on the temporary financing for the cash component of the Offer assuming the repayment of such financing from the receipt of cash proceeds from the sale of certain Placer Dome operations to Goldcorp.
(c) |  | A decrease in other expense by $21 million to de-recognize non-recurring transaction costs recorded by Placer Dome relating to the Barrick offer.

(g) |  | An increase in cash and equivalents by $152 million with a corresponding increase in Placer Dome’s capital stock, to reflect the proceeds received by Placer Dome on exercise of 10.1 million in-the-money Placer Dome stock options.
(h) |  | A reduction in capitalized mining costs by $240 million to de-recognize this asset of Placer Dome, which will not be recorded as a separate identifiable asset on acquisition.
(i) |  | A reduction in other assets by $17 million to de-recognize deferred debt issue costs of Placer Dome that will not be recorded as a separate identifiable asset on acquisition.
(j) |  | The de-recognition of goodwill of $454 million that was recorded by Placer Dome for previous business combinations.
(k) |  | An adjustment of $8,500 million to reflect the unallocated purchase price.

4 n Segment Information
Our operations are managed on a regional basis. Our four regional business units are North America, Australia/Africa, South America and Russia/Central Asia. Financial information for each of our mines and our exploration group is reviewed regularly by our chief operating decision maker.
Segment income for operating segments comprises segment revenues less segment operating costs and segment amortization in the format that internal management reporting is presented to the chief operating decision maker. For internal management reporting purposes, we measure segment revenues and income using the average consolidated realized gold selling price for each period. Segment expenses represent our internal presentation of costs incurred to produce gold at each operating mine, and exclude the following costs that we do not allocate to operating segments: environmental remediation costs at closed mines; regional business unit overhead; amortization of corporate assets; business development costs; administration costs; impairments of long-lived assets; other income/expense; and the costs of financing their activities. Segment expenses for development projects and the exploration group represent expensed exploration, mine development and mine start-up costs.

5 n Revenue and Gold Sales Contracts

For the years ended December 31 |  | 2005 |  |  | 2004 |  |  | 2003 |
Gold bullion sales |  |  |  |  |  |  |  |  |  |  |  |
Spot market sales |  | $ | 1,940 |  |  | $ | 1,111 |  |  | $ | 426 |
Gold sales contracts |  |  | 300 |  |  |  | 709 |  |  |  | 1,504 |

|  | $ | 2,350 |  |  | $ | 1,932 |  |  | $ | 2,035 |

We record revenue when the following conditions are met: persuasive evidence of an arrangement exists; delivery and transfer of title have occurred under the terms of the arrangement; the price is fixed or determinable; and collectability is reasonably assured.
Bullion Sales
We record revenue from gold and silver bullion sales at the time of physical delivery, which is also the date that title to the gold or silver passes. The sales price is fixed at the delivery date based on either the terms of gold sales contracts or the gold spot price. Incidental revenues from the sale of by-products such as silver are classified within cost of sales.
At December 31, 2005, we had fixed-price gold sales contracts with various customers for a total of 12.5 million ounces of future gold production and floating-price gold sales contracts for 0.7 million ounces. In 2005, we allocated 6.5 million ounces of fixed-price gold sales contracts specifically to Pascua-Lama. The allocation of these contracts will help reduce gold price risk at Pascua-Lama and will help secure financing for its construction. In addition to the gold sales contracts allocated to Pascua-Lama, we have 6 million ounces of Corporate gold sales contracts that we intend to settle through delivery of future gold production from our operating mines and development projects, excluding Pascua-Lama. The terms of the contracts are governed by master trading agreements (MTAs) that we have in place with the customers. The contracts have final delivery dates primarily over the next 10 years, but we have the right to settle these contracts at any time over this period. Contract prices are established at inception through to an interim date. If we do not deliver at this interim date, a new interim date is set. The price for the new interim date is determined in accordance with the MTAs which have contractually agreed price adjustment mechanisms based on the market gold price. The MTAs have both fixed and floating price mechanisms. The fixed-price mechanism represents the market price at the start date (or previous interim date) of the contract plus a premium based on the difference between the forward price of gold and the current market price. If at an interim date we opt for a floating price, the floating price represents the spot market price at the time of delivery of gold adjusted based on the difference between the previously fixed price and the market gold price at that interim date. The final realized selling price under a contract primarily depends upon the timing of the actual future delivery date, the market price of gold at the start of the contract and the actual amount of the premium of the forward price of gold over the spot price of gold for the periods that fixed selling prices are set. The mark-to-market value of the fixed-price gold sales contracts (at December 31, 2005) was negative $1,453 million for the Pascua-Lama gold sales contracts and negative $1,277 million for the Corporate gold sales contracts.
The difference between the forward price of gold and the current market price, referred to as contango, can be expressed as a percentage that is closely correlated to the difference between US dollar interest rates and gold lease rates. Historically short-term gold lease rates have been lower than longer-term rates. We use gold lease rate swaps to achieve a more economically optimal term structure for gold lease rates implicit in contango. Under the swaps we receive a fixed gold lease rate, and pay a floating gold lease rate, on a notional 1 million ounces of gold spread from 2005 to 2013. The swaps are associated with fixed-price gold sales contracts with expected delivery dates beyond 2006. Lease rate swaps are classified as non-hedge derivatives (note 16c) and had a fair value of $66 million at December 31, 2005 (2004: $74 million).
Floating spot price sales contracts were previously fixed-price forward sales contracts for which, in accordance with the terms of our MTAs, we have elected to receive floating spot gold and silver prices, adjusted based on the difference between the spot price and the contract price at the time of such election. Floating prices were elected for these contracts so that we could economically regain spot gold price leverage under the terms of delivery into these contracts. Furthermore, floating price mechanisms were elected for these contracts at a time when the then current market price was higher than the fixed price in the contract. The mark-to-market value of these contracts (at December 31, 2005) was negative $89 million, which equates to an average reduction to the future spot sales price of approximately $127 per ounce, when we deliver gold at spot prices against these contracts.
At December 31, 2005, one customer made up 11% of the ounces committed under gold bullion sales contracts.

#####

Concentrate Sales
Our Eskay Creek and Bulyanhulu mines produce gold in concentrate form. Our Pascua-Lama mine will also produce gold in concentrate form. Under the terms of concentrate sales contracts with independent smelting companies, gold sales prices are set on a specified future date after shipment based on market prices. We record revenues under these contracts at the time of shipment, which is also when title passes to the smelting companies, using forward market gold prices on the expected date that final sales prices will be fixed. Variations between the price recorded at the shipment date and the actual final price set under the smelting contracts are caused by changes in market gold prices, and result in an embedded derivative in the accounts receivable. The embedded derivative is recorded at fair value each period until final settlement occurs, with changes in fair value classified as a component of revenue. The notional amount typically outstanding is between ten and fifteen thousand ounces.
6 n Cost of Sales

For the years ended December 31 |  | 2005 |  |  | 2004 |  |  | 2003 |
Cost of goods sold1 |  | $ | 1,265 |  |  | $ | 1,128 |  |  | $ | 1,118 |
By-product revenues2 |  |  | (132 | ) |  |  | (146 | ) |  |  | (114 | )
Royalty expense |  |  | 63 |  |  |  | 53 |  |  |  | 50 |
Mining taxes |  |  | 18 |  |  |  | 12 |  |  |  | 15 |
|  | $ | 1,214 |  |  | $ | 1,047 |  |  | $ | 1,069 |

1. |  | Cost of goods sold includes accretion expense at producing mines of $11 million (2004: $11 million; 2003: $10 million). The cost of inventory sold in the period reflects all components capitalized to inventory, except that, for presentation purposes the component of inventory cost relating to amortization of property, plant and equipment is classified in the income statement under “amortization”. Some companies present this amount under “cost of sales”. The amount presented in amortization rather than cost of sales was $409 million in 2005; $425 million in 2004 and $497 million in 2003. In 2004, cost of goods sold includes the reversal of $15 million of accrued costs on resolution of the Peruvian tax assessment (see note 8).
2. |  | We use silver sales contracts to sell a portion of silver produced as a by-product. Silver sales contracts have similar delivery terms and pricing mechanisms as gold sales contracts. At December 31, 2005, we had fixed-price commitments to deliver 14.8 million ounces of silver at an average price of $5.92 per ounce and floating spot price silver sales contracts for 7.5 million ounces over periods primarily of up to 10 years. The mark-to-market on silver sales contracts (at December 31, 2005) was negative $52 million.

Royalties
Certain of our properties are subject to royalty arrangements based on mineral production at the properties. The most significant royalties are at the Goldstrike and Bulyanhulu mines and the Pascua-Lama and Veladero projects. The primary type of royalty is a net smelter return (NSR) royalty. Under this type of royalty we pay the holder an amount calculated as the royalty percentage multiplied by the value of gold production at market gold prices less third-party smelting, refining and transportation costs. Most Goldstrike production is subject to an NSR or net profits interest (NPI) royalty. The highest Goldstrike royalties are a 5% NSR and a 6% NPI royalty. Bulyanhulu is subject to an NSR-type royalty of 3%. Pascua-Lama gold production from the areas located in Chile is subject to a gross proceeds sliding scale royalty, ranging from 1.5% to 10%, and a 2% NSR on copper production. For areas located in Argentina, Pascua-Lama is subject to a 3% NSR on extraction of all gold, silver and other minerals. Production at Veladero is subject to a 3.75% NSR on extraction of all gold, silver and other minerals. Production at Lagunas Norte is subject to a 2.51% NSR on extraction of all gold and other minerals.
Royalty expense is recorded at the time of sale of gold production, measured using the applicable royalty percentage for NSR royalties or estimates of NPI amounts.

The principal factors that caused us to test this asset group for impairment included: downward revisions to proven and probable reserves; the impact of the continued strengthening of the C$ against the US$ and upward revisions to expected asset retirement costs in the fourth quarter of 2004. An impairment charge of $58 million was recorded, which represents the amount by which the carrying amount of the asset group exceeds its estimated fair value. Fair value was estimated using the method described in note 13c.
2. |  | At the end of 2004, upon completion of the exploration program for the year, we assessed the results and updated our future plans for various exploration properties in Peru that were originally acquired through the Arequipa acquisition in 1996. We concluded that the results and future potential did not merit any further investment for these properties. The assets were tested for impairment, and an impairment charge of $67 million was recorded that reflects the amounts by which their carrying amounts exceed their estimated fair values. The fair value of this group of assets was judged to be minimal due to the unfavorable results of exploration work on the properties.

1. |  | In 2005, we sold some land positions in Australia. In 2004 we sold various mining properties, including the Holt-McDermott mine in Canada and certain land positions around our inactive mine sites in the United States. In 2003 we sold various mining properties, including several land positions around inactive mine sites in the United States, as well as the East Malartic Mill and Bousquet mine in Canada. The majority of these land positions were fully amortized in prior years and therefore any proceeds generate gains on sale, before selling costs and taxes.

Kabanga Transaction
In April 2005, we finalized a joint-venture agreement with Falconbridge Limited (“Falconbridge”) for the Kabanga nickel deposit and related concessions located in Tanzania. Under the terms of the agreement, Falconbridge acquired a 50% indirect joint venture interest for $15 million cash and a funding commitment and has agreed to be the operator of the joint venture. On closing of the transaction with Falconbridge we recorded a gain of $15 million.
Over the next several years, Falconbridge will fund and conduct a further $50 million work plan that will include additional exploration and infill drilling, and technical work to update the resource model for Kabanga and bring the project towards feasibility. Falconbridge has initiated the establishment of a dedicated team in Tanzania to coordinate and advance the work plan. After expenditures of $50 million, Falconbridge will decide on whether to proceed with the project. If Falconbridge proceeds with the project, they will fund the next $95 million of any project development expenditures to advance the Kabanga project. Thereafter, Falconbridge and Barrick will share equally in joint-venture revenues and expenditures. Until Falconbridge has fully funded its commitment under the agreement, we are not obligated to share in any revenues and expenditures and none of the expenditures on the project will be recorded in our financial statements.
Environmental Remediation Costs
During the production phases of a mine, we incur and expense the cost of various activities connected with environmental aspects of normal operations, including compliance with and monitoring of environmental regulations; disposal of hazardous waste produced from normal operations; and operation of equipment designed to reduce or eliminate environmental effects. In limited circumstances, costs to acquire and install plant and equipment are capitalized during the production phase of a mine if the costs are expected to mitigate risk or prevent future environmental contamination from normal operations.
When a contingent loss arises from the improper use of an asset, a loss accrual is recorded if the loss is probable and reasonably estimable. Amounts recorded are measured on an undiscounted basis, and adjusted as further information develops or if circumstances change. Recoveries of environmental remediation costs from other parties are recorded as assets when receipt is deemed probable.
Inmet Settlement
In November 2003, we paid Inmet C$111 million (US$86 million), in full settlement of the Inmet litigation. The settlement resulted in an expense of US$14 million in fourth quarter 2003, combined with post-judgment interest of $2 million in the first nine months of 2003.

Outcome of Tax Uncertainties
Peruvian Tax Assessment
On September 30, 2004, the Tax Court of Peru issued a decision in our favor in the matter of our appeal of a 2002 income tax assessment of $32 million, excluding interest and penalties. The 2002 income tax assessment related to a tax audit of our Pierina Mine for the 1999 and 2000 fiscal years. The assessment mainly related to the validity of a revaluation of the Pierina mining concession, which affects its tax basis. Under the valuation proposed by the Peruvian tax agency, SUNAT, the tax basis of the Pierina mining concession would have changed from what we previously assumed with a resulting increase in current and deferred income taxes. The full life-of-mine effect on current and deferred income tax liabilities totaling $141 million was fully recorded at December 31, 2002, as well as other related costs of about $21 million ($15 million post-tax).
In January 2005, we received confirmation in writing that there would be no appeal of the September 30, 2004 Tax Court of Peru decision. The confirmation concluded the administrative and judicial appeals process with resolution in Barrick’s favor. In 2004, we recorded a $141 million reduction in current and deferred income tax liabilities and a $21 million reduction in other accrued costs in 2004, $15 million of which is classified in cost of sales and $6 million of which is classified in other (income) expense. Notwithstanding the favorable Tax Court decision we received in 2004 on the 1999 to 2000 revaluation matter, on audit, SUNAT has reassessed us on the same issue for 2001 to 2003. We and our advisors believe that the audit reassessment has no merit, that we will prevail, and accordingly no provision has been booked.
Changes in Tax Status in Australia
A tax law was enacted in Australia in 2002 that allows wholly owned groups of companies resident in Australia to elect to be treated as a single entity and to file consolidated tax returns. This regime is elective and the election is irrevocable. Under certain circumstances, the rules governing the election allow for a choice to reset the tax cost basis of certain assets within a consolidated group. Our election, which was effective for our 2004 fiscal year, resulted in an estimated upward revaluation of the tax basis of our assets in Australia, by $110 million, with a corresponding $33 million adjustment to deferred taxes. In 2005, based on additional facts and refinements, the adjustment was increased by $5 million.
Also in 2004, we filed an election to use the US dollar as the functional currency for Australian tax calculations and tax returns, whereas previously the Australian dollar was used. Prior to this election, the favorable impact of changes in the tax basis of non-monetary assets caused by changes in the US$:A$ exchange rate were not recorded, as their realization was not certain. The election in 2004 created certainty about the realization of these favorable tax temporary differences and resulted in our recognition of these as deferred tax assets amounting to $48 million. The impact of the change in tax status was to increase the amount of deductible temporary differences relating to non-monetary assets by $48 million.
Release of Beginning of Year Valuation Allowances
In 2005, we released valuation allowances totaling $31 million in Argentina, relating to the effect of the higher gold price environment and the anticipated commencement of sales in 2006. We released valuation allowances of $2 million in Canada reflecting utilization of capital losses.

In 2004, we released valuation allowances totaling $5 million relating to the consolidated tax return election in Australia. Valuation allowances released in 2003 mainly included: $21 million in North America following a corporate reorganization of certain subsidiaries that enabled us to utilize certain previously unrecognized tax assets; $16 million in Australia realized in 2003 due to an increase in taxable income from higher gold prices; and $15 million in Argentina after the approval to begin construction of our new Veladero mine and classification of mineralization as a proven and probable reserve.

Earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if additional common shares are assumed to be issued under securities that entitle their holders to obtain common shares in the future. The number of additional shares for inclusion in diluted earnings per share calculations is determined using the treasury stock method, whereby stock options, whose exercise price is less than the average market price of our common shares, are assumed to be exercised and the proceeds are used to repurchase common shares at the average market price for the period. The incremental number of common shares issued under stock options and repurchased from proceeds is included in the calculation of diluted earnings per share.
On January 19, 2006 and February 3, 2006, together, we issued 304 million shares to acquire a 94% interest in the outstanding common shares of Placer Dome. We intend to acquire the remaining 6% interest through a compulsory acquisition procedure.

2. |  | At December 31, 2005, there were no available-for-sale securities in an unrealized loss position.

Available-for-sale securities are recorded at fair value with unrealized gains and losses recorded in other comprehensive income (“OCI”). Realized gains and losses are recorded in earnings when investments mature or on sale, calculated using the average cost of securities sold. If the fair value of an investment declines below its carrying amount, we undertake an assessment of whether the impairment is other-than-temporary. We consider all relevant facts or circumstances in this assessment, particularly: the length of time and extent to which fair value has been less than the carrying amount; the financial condition and near-term prospects of the investee, including any specific events that have impacted its fair value; both positive and negative evidence that the carrying amount is recoverable within a reasonable period of time; and our ability and intent to hold the investment for a reasonable period of time sufficient for an expected recovery of the fair value up to or beyond the carrying amount. We record in earnings any unrealized declines in fair value judged to be other than temporary. Total proceeds from the sale of investments were $10 million in 2005 (2004: $9 million; 2003: $8 million).

Investment in Celtic Resources Holdings PLC (“Celtic”)
On January 5, 2005, we completed a subscription for 3,688,191 units of Celtic for a price of $7.562 per unit for a total cost of $30 million. Each unit consisted of one ordinary share of Celtic and one-half of one share purchase warrant. On June 1, 2005, the number of warrants held increased under the terms of the subscription agreement by 922,048 warrants to 2,766,143 warrants. Each whole warrant entitles us to acquire one ordinary share of Celtic for $7.562, expiring on December 31, 2007. We allocated $25 million to the ordinary shares and $5 million to the share purchase warrants based on their relative fair values at acquisition. At December 31, 2005, we held a 9% combined direct and indirect interest in Celtic’s outstanding common shares. The investment in common shares is classified as an available-for-sale security. In the second half of 2005, the fair value of the

investment in common shares declined below cost and at the end of 2005 we concluded that the impairment was “other-than-temporary” and recorded a $12 million impairment charge. We concluded that the share purchase warrants are derivative instruments as defined by FAS 133. The warrants, which are classified as non-hedge derivatives, are recorded at their estimated fair value in the balance sheet with changes in fair value recorded in non-hedge derivative gains/losses. The fair value of the share purchase warrants was $0.5 million at December 31, 2005.
At the time of the initial subscription, Celtic granted us the right to acquire 50% of any interest in any mineral property in Kazakhstan that Celtic acquires in the future for a period of 12 months after any such acquisition for an amount equal to 50% of the cost to Celtic of its interest in the mineral property. No such rights have been exercised since the initial subscription.

Under the equity method we record our equity share of the income or loss of equity investees each period. On acquisition of an equity investment the underlying identifiable assets and liabilities of an equity investee are recorded at fair value and the income or loss of equity investees is based on these fair values. If the cost of any equity investment exceeds the total amount of the fair value of identifiable assets and liabilities, any excess is accounted for in a manner similar to goodwill, with the exception that an annual goodwill impairment test is not required. The carrying amount of each investment in an equity investee is evaluated for impairment using the same method as an available-for-sale security.
Highland Gold Mining PLC (“Highland”)
We hold a 20% interest in Highland that was acquired for cash in three tranches: 11.1 million common shares for a cost of $46 million in 2003; 9.3 million common shares for a cost of $40 million in 2004; and 11 million common shares in 2005 for a cost of $50 million.
Following the increase in our ownership to 20% in 2005, we re-evaluated the accounting method used for this investment and concluded that the equity method is the most appropriate. Previously the investment was classified as an available-for-sale security. We have recorded our equity share of income or loss of Highland each period based on our actual ownership interest for the period from fourth quarter 2003. Under a transition to equity accounting, US GAAP requires financial statements for prior periods to be revised to reflect the equity accounting treatment.
The difference between the cost of our investment in Highland and the underlying historic cost of net assets was $108 million at April 30, 2005. After finalizing valuations for the assets and liabilities of Highland in fourth quarter 2005, the difference between the cost of our investment and the underlying fair value of assets and liabilities, representing goodwill, was $85 million. On completion of the valuations, we revised our equity pick up to reflect accounting based on the fair values of Highland’s assets and liabilities.
We have participation agreements with Highland, under which we have the right to participate for up to 50% in any acquisition made by Highland in Russia, with a similar right for Highland on any acquisition made by us in certain regions in Russia, excluding Irkutsk. We have a right of first refusal with respect to any third-party investment in Highland’s Mayskoye property in the Chukotka region, Russia, and we plan to pursue discussions with Highland regarding Mayskoye.
On June 29, 2005, we entered into a purchase agreement with Highland pursuant to which we purchased a 50% interest in the Taseevskoye deposit (“Taseevskoye”). The purchase price was $13 million. Highland currently holds Taseevskoye through a subsidiary that owns other assets and liabilities. Highland has agreed to restructure the ownership of Taseevskoye into a separate Russian company. In connection with the purchase, Highland issued to us a warrant which entitles us to apply the purchase price as payment for an equivalent number of Highland shares, based on a price of $3.10 per share, subject to adjustment under certain circumstances, if Highland does not restructure the ownership of Taseevskoye prior to June 1, 2006.
During the period between the signing of the Taseevskoye purchase agreement and the time that the ownership of Taseevskoye is restructured, we agreed to fund our proportionate share of any expenditures relating to Taseevskoye. Highland agreed to deliver to us a warrant

that entitles us to apply the amount of interim expenditures paid by us as payment for an equivalent number of Highland shares based on a price of $3.10 per share, subject to adjustment in certain circumstances, if Highland does not complete the restructuring by June 1, 2006. By December 31, 2005, we had funded interim expenditures totaling $0.5 million, and we had received a warrant for the same amount.
Diamondex Resources Limited (“Diamondex”)
We completed a subscription for 11,111,111 units of Diamondex for $8 million in 2005. Each unit consists of one ordinary share of Diamondex and one share purchase warrant. We hold a 14% interest in the outstanding common shares of Diamondex (25% assuming exercise of the share purchase warrants). We allocated the cost as follows: $7 million to the ordinary shares and $1 million to the share purchase warrants. We record our equity share of the income or loss of Diamondex each period based on our total 14% interest in outstanding common shares.

Inventories
Material extracted from our mines is classified as either ore or waste. Ore represents material that can be mined, processed into a saleable form, and sold at a profit. Ore is recorded as an asset that is classified within inventory at the point it is extracted from the mine. Ore is accumulated in stockpiles that are subsequently processed into gold in a saleable form under a mine plan that takes into consideration optimal scheduling of production of our reserves, present plant capacity, and the market price of gold. Gold in process represents gold in the processing circuit that has not completed the production process, and is not yet in a saleable form.
Stockpiles are measured by estimating the number of tons added and removed from the stockpile, the number of contained ounces or pounds (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 a stockpile 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, depreciation, depletion and amortization relating to mining operations, and removed at each stockpile’s average cost per recoverable unit.
The recovery of gold from certain oxide ores is achieved through the heap leaching process. Our Pierina, Lagunas Norte, and Veladero mines all are using a 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 “pregnant” solution is further processed in a plant where the gold is recovered. For accounting purposes, costs are added to ore on leach pads based on current mining costs, including applicable depreciation, depletion 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.
Estimates of recoverable gold on the leach pads are calculated from the quantities of ore placed on the leach 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, leach pads recover between 50% and 95% of the 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 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, our operating results have not been materially impacted by variations between the estimated and actual recoverable quantities of gold on its leach pads. At December 31, 2005 and 2004, the weighted-average cost per recoverable ounce of gold on leach pads was $164 and $153 per ounce (unaudited), respectively. 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.
The ultimate recovery of gold from a leach pad will not be known until the leaching process is concluded. Based on current mine plans, we expect to place the last ton of ore on our current leach pads at dates ranging from 2007 to 2021 (unaudited). Including the estimated time required for residual leaching, rinsing and reclamation activities, we expect that our leaching operations will terminate within approximately six years (unaudited) following the date that the last ton of ore is placed on the leach pad.
The current portion of ore inventory on leach pads is determined based on estimates of the quantities of gold at each balance sheet date that we expect to recover during the next 12 months.

At Goldstrike, we expect to fully process the autoclave stockpile by 2008 (unaudited) and the roaster stockpile by 2023 (unaudited). At Kalgoorlie, we expect to fully process the stockpile by 2016 (unaudited).
We record gold in process, gold doré and gold in concentrate form at average cost, less provisions required to reduce inventory to market value. Average cost is calculated based on the cost of inventory at the beginning of a period, plus the cost of inventory produced in a period. Costs capitalized to inventory include direct and indirect materials and consumables; direct labor; repairs and maintenance; utilities; amortization of property, plant and equipment; stripping costs; and local mine administrative expenses. Costs are removed from inventory and recorded in cost of sales and amortization expense based on the average cost per ounce of gold in inventory.
Mine operating supplies are recorded at purchase cost, less provisions to reduce slow-moving and obsolete supplies to market value. We recorded provisions to reduce the cost of slow moving and obsolete supplies inventory to market value as follows: 2005 — $12 million in cost of sales and $3 million in expensed development costs; 2004 — $9 million in cost of sales; 2003 — $3 million in cost of sales.

a) Acquired Mineral Properties and Capitalized Mine Development Costs
Exploration and Development Stage Properties
We capitalize the cost of acquisition of land and mineral rights. The cost is allocated between proven and probable reserves and mineralization not considered proven and probable reserves at the date of acquisition, based on relative fair values. If we later establish that some mineralization meets the definition of proven and probable gold reserves, we classify a portion of the capitalized acquisition cost as relating to reserves.

Barrick Annual Report 2005 |  | Notes to Consolidated Financial Statements n 103

#####

After acquisition, various factors can affect the recoverability of the capitalized cost of land and mineral rights, particularly the results of exploration drilling. The length of time between the acquisition of land and mineral rights and when we undertake exploration work varies based on the prioritization of our exploration projects and the size of our exploration budget. If we conclude that the carrying amount of land and mineral rights is impaired, we reduce this carrying amount to estimated fair value through an impairment charge.
We capitalize costs incurred at development projects that meet the definition of an asset after mineralization is classified as proven and probable gold reserves (as defined by United States reporting standards). Before classifying mineralization as proven and probable gold reserves, costs incurred at development projects are considered exploration costs and are expensed as incurred. Effective May 1, 2004, we determined that mineralization at Lagunas Norte met the definition of proven and probable reserves for United States reporting purposes. Following this determination, we began capitalizing costs that meet the definition of an asset at Lagunas Norte prospectively for future periods. At new mines, the cost of start-up activities such as recruiting and training is expensed as incurred.
At December 31, 2005 the following assets were in an exploration, development or construction stage and amortization of the capitalized costs had not yet begun.

Total |  | $ | 883 |  |  |  |  |

In 2005, amortization of property, plant and equipment at our Tulawaka, Lagunas Norte, and our Veladero mines began after the mines moved from construction into the production phase. Amortization also began in 2005 at the Nevada Power Plant that was built to supply power for the Goldstrike mine as it moved from construction into the production phase.
Interest cost is considered an element of the historical cost of an asset when a period of time is necessary to prepare it for its intended use. We capitalize interest costs to assets under development or construction while activities are in progress. We stop capitalizing interest costs when construction of an asset is substantially complete and it is ready for its intended use. We measure the amount capitalized based on cumulative capitalized costs, exclusive of the impact, if any, of impairment charges on the carrying amount of an asset.
Producing Mines
We start amortizing capitalized mineral property acquisition and mine development costs when production begins. Amortization is calculated using the “units-of-production” method, where the numerator is the number of ounces produced and the denominator is the estimated recoverable ounces of gold contained in proven and probable reserves.
During production at underground mines, we incur development costs to build new shafts, drifts and ramps that will enable us to physically access ore underground. The time over which we will continue to incur these costs depends on the mine life, and in some cases could be up to 25 years. These underground development costs are capitalized as incurred. Costs incurred and capitalized to enable access to specific ore blocks or areas of the mine, and which only provide an economic benefit over the period of mining that ore block or area, are attributed to earnings using the units-of-production method where the denominator is estimated recoverable ounces of gold contained in proven and probable reserves within that ore block or area. If capitalized underground development costs provide an economic benefit over the entire mine life, the costs are attributed to earnings using the units-of-production method, where the denominator is the estimated recoverable ounces of gold contained in total accessible proven and probable reserves.

#####

b) Buildings, Plant and Equipment
We record buildings, plant and equipment at cost. We capitalize costs that extend the productive capacity or useful economic life of an asset. Costs incurred that do not extend the productive capacity or useful economic life of an asset are considered repairs and maintenance and expensed as incurred. We amortize the capitalized cost of assets less any estimated residual value, using the straight-line method over the estimated useful economic life of the asset based on their expected use in our business. The longest estimated useful economic life for buildings and equipment at ore processing facilities is 25 years and for mining equipment is 15 years.
In the normal course of our business, we have entered into certain leasing arrangements whose conditions meet the criteria for the leases to be classified as capital leases. For capital leases, we record an asset and an obligation at an amount equal to the present value at the beginning of the lease term of minimum lease payments over the lease term. In the case of all our leasing arrangements, there is transfer of ownership of the leased assets to us at the end of the lease term and therefore we amortize these assets on a basis consistent with our other owned assets.
c) Impairment Evaluations — Operating Mines and Development Projects
We review and test the carrying amounts of assets when events or changes in circumstances suggest that the carrying amount may not be recoverable. We group assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. For operating mines and development projects, all assets are included in one group. If there are indications that an impairment may have occurred, we prepare estimates of expected future cash flows for each group of assets. Expected future cash flows are based on a probability-weighted approach applied to potential outcomes.
Estimates of expected future cash flow reflect:

n |  | Estimated sales proceeds from the production and sale of recoverable ounces of gold contained in proven and probable reserves;
n |  | Expected future commodity prices and currency exchange rates (considering historical and current prices, price trends and related factors);
n |  | Expected future operating costs and capital expenditures to produce proven and probable gold reserves based on mine plans that assume current plant capacity, and exclude the impact of inflation;
n |  | Expected cash flows associated with value beyond proven and probable reserves, which includes the expected cash outflows required to develop and extract the value beyond proven and probable reserves; and
n |  | Environmental remediation costs excluded from the measurement of asset retirement obligations.

We record a reduction of a group of assets to fair value as a charge to earnings if expected future cash flows are less than the carrying amount. We estimate fair value by discounting the expected future cash flows using a discount factor that reflects the risk-free rate of interest for a term consistent with the period of expected cash flows.
d) Capital Commitments
At December 31, 2005, we had capital commitments of $85 million that principally relate to construction activities at our development projects.

1. |  | The 71/2% debentures have a principal amount of $500 million and mature on May 1, 2007. The debentures have been designated in a fair value hedge relationship and consequently the carrying amount at December 31, 2005 represents the estimated fair value at each balance sheet date.
2. |  | On November 12, 2004, we issued $400 million of debentures at a $3 million discount that mature on November 15, 2034.
3. |  | On November 12, 2004, we issued $350 million of debentures at a $2 million discount that mature on November 15, 2014.
4. |  | One of our wholly owned subsidiaries, Minera Argentina Gold S.A. in Argentina has a variable-rate limited recourse amortizing loan facility for $250 million. We have guaranteed the loan until completion occurs, after which it will become non-recourse. The loan is insured for political risks by branches of the Canadian and German governments.
5. |  | One of our wholly owned subsidiaries, Kahama Mining Corporation Ltd. in Tanzania, has a variable-rate recourse amortizing loan for $119 million. The loan is insured for political risks equally by branches of the Canadian government and the World Bank. In second quarter 2005, the terms of the financing were amended, with the lender having recourse in return for a reduction in the spread over Libor on the financing, and the loan convenants were also simplified.
6. |  | Certain of our wholly owned subsidiaries have issued variable-rate, tax-exempt bonds of $25 million (due 2029) and $38 million (due 2032) for a total of $63 million.
7. |  | By December 31, 2005, a total of $103 million had been drawn down under a $110 million build to suit facility held by one of our wholly owned subsidiaries, Minera Barrick Misquichilca (MBM). We repaid $23 million on September 30, 2005, with the remaining $80 million repayable in 20 equal quarterly installments of $4 million commencing in fourth quarter 2005. The lease facility has an implied interest rate of Libor plus 2.5% for the first 12 installments and Libor plus 2.6% for the last 8 installments.
8. |  | In 2005, MBM finalized a second build to suit lease facility for $30 million, which is being used to finance the extension of the leach pad at the Lagunas Norte mine.
9. |  | In second quarter 2005, MBM issued $50 million of public debt securities in the Peruvian capital markets. The net proceeds were used to partially fund the construction of the Lagunas Norte mine. The securities bear interest at Libor plus 1.72%, and mature in 2013.
10. |  | We have a credit and guarantee agreement with a group of banks (the “Lenders”), which requires the Lenders to make available to us a credit facility of up to $1 billion or the equivalent amount in Canadian currency. The credit facility, which is unsecured, matures in April 2010 and has an interest rate of Libor plus 0.27% to 0.35% when used, and an annual fee of 0.08%. As at December 31, 2005, we had not drawn any amounts under the credit facility. In first quarter 2006, we drew down $1 billion under this credit facility to fund a portion of the cash consideration for the acquisition of Placer Dome — see note 3a.

c) Use of Derivative Instruments (“Derivatives”) in Risk Management
In the normal course of business, our assets, liabilities and forecasted transactions are impacted by various market risks including:

Item |  | Impacted by
n Cost of sales |  |
n Consumption of diesel fuel and propane |  | n Prices of diesel fuel and propane
n Local currency denominated expenditures |  | n Currency exchange rates — US dollar versus A$, C$, and ARS
n Administration costs in local currencies |  | n Currency exchange rates — US dollar versus A$ and C$
n Capital expenditures in local currencies |  | n Currency exchange rates — US dollar versus A$, C$, ARS, and €
n Interest earned on cash |  | n US dollar interest rates
n Fair value of fixed-rate debt |  | n US dollar interest rates

Under our risk management policy we seek to mitigate the impact of these market risks to control costs and enable us to plan our business with greater certainty. The time-frame and manner in which we manage these risks varies for each item based upon our assessment of the risk and available alternatives for mitigating risk. For these particular risks, we believe that derivatives are an effective means of managing risk.
The primary objective of the hedging elements of our derivative positions is that changes in the values of hedged items are offset by changes in the values of derivatives. Most of the derivatives we use meet the FAS 133 hedge effectiveness criteria and are designated in a hedge accounting relationship. Some of the derivative positions are effective in achieving our risk management objectives but they do not meet the strict FAS 133 hedge effectiveness criteria, and they are classified as “non-hedge derivatives”.
Our use of derivatives is based on established practices and parameters, which are subject to the oversight of the Finance Committee of the Board of Directors. A Compliance Function independent of the Corporate Treasury Group monitors derivative transactions and has responsibility for recording and accounting for derivatives.
Accounting Policy for Derivatives
We record derivatives on the balance sheet at fair value except for gold and silver sales contracts, which are excluded from the scope of FAS 133, because the obligations will be met by physical delivery of our gold and silver production and they meet the other requirements set out in paragraph 10(b) of FAS 133. In addition, our past sales practices, productive capacity and delivery intentions are consistent with the definition of a normal sales contract. Accordingly, we have elected to designate our gold and silver sales contracts as “normal sales contracts” with the result that the principles of FAS 133 are not applied to them. Instead we apply revenue recognition accounting principles as described in note 5.
On the date we enter into a derivative that is accounted for under FAS 133, we designate it as either a hedging instrument or a non-hedge derivative.
A hedging instrument is designated in either:

n |  | a fair value hedge relationship with a recognized asset or liability; or
n |  | a cash flow hedge relationship with either a forecasted transaction or the variable future cash flows arising from a recognized asset or liability.

At the inception of a hedge, we formally document all relationships between hedging instruments and hedged items, including the related risk-management strategy. This documentation includes linking all hedging instruments to either specific assets and liabilities, specific forecasted transactions or variable future cash flows. It also includes the method of assessing retrospective and prospective hedge effectiveness. In cases where we use regression analysis to assess prospective effectiveness, we consider regression outputs for the coefficient of determination (R-squared), the slope coefficient and the t-statistic to assess whether a hedge is expected to be highly effective. Each period, using a dollar offset approach, we retrospectively assess whether hedging instruments have been highly effective in offsetting changes in the fair value of hedged items and we measure the amount of any hedge ineffectiveness. We also assess each period whether hedging instruments are expected to be highly effective in the future. If a hedging instrument is not expected to be highly effective, we stop hedge accounting prospectively. In this case accumulated gains or losses remain in OCI until the hedged item affects earnings. We also stop hedge accounting prospectively if:

n |  | a derivative is settled;
n |  | it is no longer highly probable that a forecasted transaction will occur; or
n |  | we de-designate a hedging relationship.

#####

If we conclude that it is probable that a forecasted transaction will not occur in the originally specified time frame, or within a further two-month period, gains and losses accumulated in OCI are immediately transferred to earnings. In all situations when hedge accounting stops, a derivative is classified as a non-hedge derivative prospectively. Cash flows from derivative transactions are included under operating activities, except for derivatives designated as a cash flow hedge of forecasted capital expenditures, which are included under investing activities.
Changes in the fair value of derivatives each period are recorded as follows:

n |  | Fair value hedges: recorded in earnings as well as changes in fair value of the hedged item.
n |  | Cash flow hedges: recorded in OCI until earnings are affected by the hedged item, except for any hedge ineffectiveness which is recorded in earnings immediately.
n |  | Non-hedge derivatives: recorded in earnings.

US Dollar Interest Rate Contracts
Cash Flow Hedges — Cash Balances
Receive-fixed swaps have been designated against the first $425 million of our cash balances as a hedge of the variability of forecasted interest receipts on the balances caused by changes in Libor.
Each period the effective portion of changes in the fair value of the swaps, which relates to future interest receipts, is recorded in OCI. Also, as interest is received and recorded in earnings, an amount equal to the difference between the fixed-rate interest earned on the swaps and the variable-rate interest earned on cash is recorded in earnings as a component of interest income.
Fair Value Hedges
Receive-fixed swaps totaling $500 million have been designated against the 71/2% debentures as a hedge of the variability in the fair value of the debentures caused by changes in Libor. We have concluded that the hedges are 100% effective under FAS 133, because the critical terms (including: notional amount, maturity date, interest payment and underlying interest rate — i.e. Libor) of the swaps and the debentures are the same. Changes in fair value of the swaps, together with an equal corresponding change in fair value of the debentures, caused by changes in Libor, are recorded in earnings each period. Also, as interest payments on the debentures are recorded in earnings, an amount equal to the difference between the fixed-rate interest received under the swap less the variable-rate interest paid under the swap is recorded in earnings as a component of interest costs.

#####

Non-hedge Contracts
We use gold lease rate swaps as described in note 5. The valuation of gold lease rate swaps is impacted by market US dollar interest rates. Our non-hedge pay-fixed swap position mitigates the impact of changes in US dollar interest rates on the valuation of gold lease rate swaps.
Currency Contracts
Cash Flow Hedges
Currency contracts totaling C$788 million, A$2,213 million, and ARS$36 million have been designated against forecasted local currency denominated expenditures as a hedge of the variability of the US dollar amount of those expenditures caused by changes in currency exchange rates. Hedged items are identified as the first stated quantity of dollars of forecasted expenditures in a future month. For a C$547 million and A$2,065 million portion of the contracts, we have concluded that the hedges are 100% effective under FAS 133 because the critical terms (including notional amount and maturity date) of the hedged items and currency contracts are the same. For the remaining C$241 million and A$147 million portions, prospective and retrospective hedge effectiveness is assessed using the hypothetical derivative method under FAS 133. The prospective test involves comparing the effect of a theoretical shift in forward exchange rates on the fair value of both the actual and hypothetical derivative. The retrospective test involves comparing the effect of historic changes in exchange rates each period on the fair value of both the actual and hypothetical derivative using a dollar offset approach. The effective portion of changes in fair value of the currency contracts is recorded in OCI until the forecasted expenditure impacts earnings. For expenditures capitalized to the cost of inventory, this is upon sale of inventory, and for capital expenditures, this is when amortization of the capital assets is recorded in earnings.
If it is probable that a hedged item will no longer occur in the originally specified time frame or within a further two-month period, the accumulated gains or losses in OCI for the associated currency contract are reclassified to earnings immediately. The identification of which currency contracts are associated with these hedged items uses a last-in, first-out (“LIFO”) approach, based on the order in which currency contracts were originally designated in a hedging relationship.
Commodity Contracts
Cash Flow Hedges
Commodity contracts totaling 2,014 thousand barrels of diesel fuel and 17 million gallons of propane have been designated against forecasted purchases of the commodities for expected consumption at our mining operations. The contracts act as a hedge of the impact of variability in market prices on the cost of future commodity purchases. Hedged items are identified as the first stated quantity in millions of barrels/gallons of forecasted purchases in a future month. Prospective and retrospective hedge effectiveness is assessed using the hypothetical derivative method under FAS 133. The prospective test is based on regression analysis of the month-on-month change in fair value of both the actual derivative and a hypothetical derivative caused by actual historic changes in commodity prices over the last three years. The retrospective test involves comparing the effect of historic changes in commodity prices each period on the fair value of both the actual and hypothetical derivative using a dollar offset approach. The effective portion of changes in fair value of the commodity contracts is recorded in OCI until the forecasted transaction impacts earnings. The cost of commodity consumption is capitalized to the cost of inventory, and therefore this is upon the sale of inventory.
If it is probable that a hedged item will no longer occur in the originally specified time frame, or within a further two-month period, the accumulated gains or losses in OCI for the associated commodity contract are reclassified to earnings immediately. The identification of which commodity contracts are associated with these hedged items uses a LIFO approach, based on the order in which commodity contracts were originally designated in a hedging relationship.
Non-hedge Contracts
Non-hedge fuel contracts are used to mitigate the risk of oil price changes on consumption at the Pierina, Eskay Creek and Lagunas Norte mines. On completion of regression analysis, we concluded that the contracts do not meet the “highly effective” criterion in FAS 133 due to currency and basis differences between contract prices and the prices charged to the mines by oil suppliers. Despite not qualifying as an accounting hedge, the contracts protect the Company to a significant extent from the effects of oil price changes.

d) Fair Value of Financial Instruments
Fair value is the value at which a financial instrument could be closed out or sold in a transaction with a willing and knowledgeable counterparty over a period of time consistent with our risk management or investment strategy. Fair value is based on quoted market prices, where available. If market quotes are not available, fair value is based on internally developed models that use market-based or independent information as inputs. These models could produce a fair value that may not be reflective of future fair value.

4. |  | Recorded at fair value based on internal valuation models that reflect forward market commodity prices, currency exchange rates and interest rates, and a discount factor that is based on market US dollar interest rates. If a forward market does not exist, we obtain broker-dealer quotations. Valuations assume all counterparties have an AA credit rating.
5. |  | Long-term debt is generally recorded at cost except for obligations that are designated in a fair-value hedge relationship, which are recorded at fair value in periods where a hedge relationship exists. The fair value of long-term debt is calculated by discounting the future cash flows under a debt obligation by a discount factor that is based on US dollar market interest rates adjusted for our credit quality.
6. |  | Recorded at fair value based on our period end closing market stock price.

e) Credit Risk
Credit risk is the risk that a third party might fail to fulfill its performance obligations under the terms of a financial instrument. For cash and equivalents and accounts receivable, credit risk represents the carrying amount on the balance sheet.
For derivatives, when the fair value is positive, this creates credit risk. When the fair value of a derivative is negative, we assume no credit risk. In cases where we have a legally enforceable master netting agreement with a counterparty, credit risk exposure represents the net amount of the positive and negative fair values for similar types of derivatives. For a net negative amount, we regard credit risk as being zero. A net positive amount for a counterparty is a reasonable measure of credit risk when there is a legally enforceable master netting agreement. We mitigate credit risk by:

n |  | entering into derivatives with high credit-quality counterparties;
n |  | limiting the amount of exposure to each counterparty; and
n |  | monitoring the financial condition of counterparties.

2. |  | For cash and equivalents and derivatives combined.

f) Risks Relating to the Use of Derivatives
By using derivatives, in addition to credit risk, we are affected by market risk and market liquidity risk. Market risk is the risk that the fair value of a derivative might be adversely affected by a change in commodity prices, interest rates, gold lease rates, or currency exchange rates, and that this in turn affects our financial condition. We manage market risk by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. We mitigate this risk by establishing trading agreements with counterparties under which we are not required to post any collateral or make any margin calls on our derivatives. Our counterparties cannot require settlement solely because of an adverse change in the fair value of a derivative.
Market liquidity risk is the risk that a derivative cannot be eliminated quickly, by either liquidating it or by establishing an offsetting position. Under the terms of our trading agreements, counterparties cannot require us to immediately settle outstanding derivatives, except upon the occurrence of customary events of default such as covenant breaches, including financial covenants, insolvency or bankruptcy. We generally mitigate market liquidity risk by spreading out the maturity of our derivatives over time.

AROs arise from the acquisition, development, construction and normal operation of mining property, plant and equipment, due to government controls and regulations that protect the environment on the closure and reclamation of mining properties. The major parts of the carrying amount of AROs relate to tailings and heap leach pad closure/rehabilitation; demolition of buildings/mine facilities; ongoing water treatment; and ongoing care and maintenance of closed mines. The fair values of AROs are measured by discounting the expected cash flows using a discount factor that reflects the credit-adjusted risk-free rate of interest. We prepare estimates of the timing and amount of expected cash flows when an ARO is incurred. We update expected cash flows to reflect changes in facts and circumstances. The principal factors that can cause expected cash flows to change are: the construction of new processing facilities; changes in the quantities of material in reserves and a corresponding change in the life of mine plan; changing ore characteristics can impact required environmental protection measures and related costs; changes in water quality that impact the extent of water treatment required; and changes in laws and regulations governing the protection of the environment. When expected cash flows increase, the revised cash flows are discounted using a current discount factor whereas when expected cash flows decrease the additional cash flows are discounted using a historic discount factor, and then in both cases any change in the fair value of the ARO is recorded. We record the fair value of an ARO when it is incurred. At producing mines AROs incurred and changes in the fair value of AROs are recorded as an adjustment to the corresponding asset carrying amounts. At closed mines, any adjustment to the fair value of an ARO is charged directly to earnings. AROs are adjusted to reflect the passage of time (accretion) calculated by applying the discount factor implicit in the initial fair-value measurement to the beginning-of-period carrying amount of the AROs. For producing mines accretion is recorded in the cost of goods sold each period. For development projects and closed mines, accretion is recorded as part of environmental remediation costs in other (income) expense. Upon settlement of an ARO, we record a gain or loss if the actual cost differs from the carrying amount of the ARO. Settlement gains are classified as environmental remediation costs in other (income) expense. Other environmental remediation costs that are not AROs as defined by FAS 143 are expensed as incurred (see note 7).

19 n Deferred Income Taxes
Recognition and Measurement
We record deferred income tax assets and liabilities where temporary differences exist between the carrying amounts of assets and liabilities in our balance sheet and their tax bases. The measurement and recognition of deferred income tax assets and liabilities takes into account: enacted rates that will apply when temporary differences reverse; interpretations of relevant tax legislation; tax planning strategies; estimates of the tax bases of assets and liabilities; and the deductibility of expenditures for income tax purposes. We recognize the effect of changes in our assessment of these estimates and factors when they occur. Changes in deferred income tax assets, liabilities and valuation allowances are allocated between net income and other comprehensive income based on the source of the change.
Deferred income taxes have not been provided on the undistributed earnings of foreign subsidiaries, which are considered to be reinvested indefinitely outside Canada. The determination of the unrecorded deferred income tax liability is not considered practicable.

Valuation Allowances
We consider the need to record a valuation allowance against deferred tax assets on a country-by-country basis, taking into account the effects of local tax law. A valuation allowance is not recorded when we conclude that sufficient positive evidence exists to demonstrate that it is more likely than not that a deferred tax asset will be realized. The main factors considered are:

n |  | historic and expected future levels of future taxable income;
n |  | opportunities to implement tax plans that affect whether tax assets can be realized; and
n |  | the nature, amount and expected timing of reversal of taxable temporary differences.

Levels of future taxable income are mainly affected by: market gold and silver prices; forecasted future costs and expenses to produce gold reserves; quantities of proven and probable gold reserves; market interest rates and foreign currency exchange rates. If these factors or other circumstances change, we record an adjustment to the valuation allowances to reflect our latest assessment of the amount of deferred tax assets that will more likely than not be realized.
A valuation allowance of $209 million has been set up against certain deferred tax assets in the United States. A majority of this valuation allowance relates to AMT credits which have an unlimited carry forward period. Increasing levels of future taxable income due to higher gold selling prices and other factors and circumstances may result in an adjustment to this valuation allowance.

20 n Capital Stock
a) Common Shares
Our authorized capital stock includes an unlimited number of common shares (issued 538,081,875 common shares); 9,764,929 First preferred shares Series A (issued nil); 9,047,619 Series B (issued nil); 1 Series C special voting share (issued 1); and 14,726,854 Second preferred shares Series A (issued nil).
We repurchased 4.47 million common shares in 2004 (2003: 8.75 million common shares) for $95 million, at an average cost of $21.20 per share (2003: $17.56 per share). This resulted in a reduction of common share capital by $35 million (2003: $67 million) and a $60 million (2003: $87 million) charge (being the difference between the repurchase cost and the average historic book value of shares repurchased) to retained earnings.
In 2005, we declared and paid dividends in US dollars totaling $0.22 per share ($118 million) (2004: $0.22 per share, $118 million; 2003: $0.22 per share, $118 million).
b) Exchangeable Shares
In connection with a 1998 acquisition, Barrick Gold Inc. (“BGI”), issued 11.1 million BGI exchangeable shares, which are each exchangeable for 0.53 of a Barrick common share at any time at the option of the holder, and have essentially the same voting, dividend (payable in Canadian dollars), and other rights as 0.53 of a Barrick common share. BGI is a subsidiary that holds our interest in the Hemlo and Eskay Creek Mines.
At December 31, 2005, 1.4 million (2004: 1.4 million) BGI exchangeable shares were outstanding, which are equivalent to 0.7 million Barrick common shares (2004: 0.7 million common shares), and are reflected in the number of common shares outstanding. We have the right to require the exchange of each outstanding BGI exchangeable share for 0.53 of a Barrick common share. While there are exchangeable shares outstanding, we are required to present summary consolidated financial information relating to BGI.

22 n Stock-Based Compensation
In 2005, following a review of various types of stock-based compensation arrangements, we introduced a new stock-based compensation plan for employees. Under the new plan, selected employees are granted restricted share units (RSUs) each year that vest on the third anniversary of the date of grant. Certain employees have the ability to elect for 50% of each annual RSU grant to be exchanged for stock options using a predetermined exchange ratio. We expect that the volume of options granted each year will decline compared to historical volumes, with a greater number of RSUs issued instead.

1. |  | The exercise price of the options is the closing share price on the day before the grant date. They vest evenly over four years, beginning in the year after granting. Options granted in July 2004 and prior are exercisable over 10 years, whereas options granted since December 2004 are exercisable over 7 years. At December 31, 2005, 12 million (2004: 13 million; 2003: 1 million) common shares, in addition to those currently outstanding, were available for granting options.

We record compensation cost for stock options based on the excess of the market price of the stock at the grant date of an award over the exercise price. Historically, the exercise price for stock options has equaled the market price of the stock at the grant date, resulting in no compensation cost.

1. |  | Different assumptions were used for the multiple stock option grants valued under the Black-Scholes method.
2. |  | Stock option grants issued after September 30, 2005 were valued using the Lattice valuation model. The volatility and risk-free interest rate assumption varied over the expected term of that stock option grant.
3. |  | Basic and diluted.

We changed the method used to value stock option grants from the Black-Scholes method to the Lattice valuation model for stock options granted after September 30, 2005. We believe the Lattice valuation model provides a more representative fair value because it incorporates more attributes of stock options such as employee turnover and voluntary exercise patterns of option holders. For options granted before September 30, 2005, fair value was determined using the Black-Scholes method. The expected volatility assumptions have been developed taking into consideration both historical and implied volatility of our US dollar share price. The risk-free rate for periods within the contractual life of the option is based on the US Treasury yield curve in effect at the time of the grant.
We use the straight-line method for attributing stock option expense over the vesting period. Stock option expense incorporates an expected forfeiture rate. The expected forfeiture rate is estimated based on historical forfeiture rates and expectations of future forfeitures rates. We make adjustments if the actual forfeiture rate differs from the expected rate.
Under the Black-Scholes model the expected term assumption takes into consideration assumed rates of employee turnover and represents the estimated average length of time stock options remain outstanding before they are either exercised or forfeited. Under the Lattice valuation model, the expected term assumption is derived from the option valuation model and is in part based on historical data regarding the exercise behavior of option holders based on multiple share-price paths. The Lattice model also takes into consideration employee turnover and voluntary exercise patterns of option holders.
As at December 31, 2005, there was $56 million of total unrecognized compensation cost relating to unvested stock options. We expect to recognize this cost over a weighted-average period of 2 years.

b) Restricted Share Units (RSUs) and Deferred Share Units (DSUs)
Under our RSU Plan, selected employees are granted RSUs, where each RSU has a value equal to one Barrick common share. RSUs vest and will be settled in cash on the third anniversary of the grant date. Additional RSUs are credited to reflect dividends paid on Barrick common shares. RSUs are recorded at fair value on the grant date, with a corresponding amount recorded as deferred compensation that is amortized on a straight-line basis over the vesting period. Changes in the fair value of the RSUs are recorded, with a corresponding adjustment to deferred compensation. Compensation expense for 2005 was $2 million (2004: $4 million; 2003: $4 million). At December 31, 2005, the weighted-average remaining contractual life of RSUs was 2.5 years.
Under our DSU plan, Directors receive 50% of their basic annual retainer in the form of DSUs, with the option to elect to receive 100% of such retainer in DSUs. Each DSU has the same value as one Barrick common share. DSUs must be retained until the Director leaves the Board, at which time the cash value of the DSUs will be paid out. Additional DSUs are credited to reflect dividends paid on Barrick common shares. DSUs are recorded at fair value on the grant date and are adjusted for changes in fair value. The fair value of amounts granted each period together with changes in fair value are expensed.

23 n Post-Retirement Benefits
a) Defined Contribution Pension Plans
Certain employees take part in defined contribution employee benefit plans. We also have a retirement plan for certain officers of the Company, under which we contribute 15% of the officer’s annual salary and bonus. Our share of contributions to these plans, which is expensed in the year it is earned by the employee, was $20 million in 2005, $19 million in 2004 and $16 million in 2003.
b) Defined Benefit Pension Plans
We have one qualified defined benefit pension plan that covers certain of our United States employees and provides benefits based on employees’ years of service. Our policy is to fund the amounts necessary on an actuarial basis to provide enough assets to meet the benefits payable to plan members under the Employee Retirement Income Security Act of 1974. Independent trustees administer assets of the plans, which are invested mainly in fixed-income and equity securities. On December 31, 2004, the qualified defined benefit plan was amended to freeze benefit accruals for all employees, resulting in a curtailment gain of $2 million.
As well as the qualified plan, we have non-qualified defined benefit pension plans covering certain employees and former directors of the Company. An irrevocable trust (“rabbi trust”) was set up to fund these plans. The fair value of assets held in this trust was $22 million in 2005 (2004: $31 million), and is recorded in our consolidated balance sheet under available-for-sale securities.
Actuarial gains and losses arise when the actual return on plan assets differs from the expected return on plan assets for a period, or when the expected and actuarial accrued benefit obligations differ at the end of the year. We amortize actuarial gains and losses over the average remaining life expectancy of plan participants, in excess of a 10% corridor.

1. |  | A minimum pension liability is recognized if the Accumulated Benefit Obligation (ABO), exceeds the fair value of the pension plan assets. The liability that is recorded is calculated by subtracting the fair value of plan assets from the ABO, adjusting this amount by the accrued/prepaid pension cost that has already been recorded on the balance sheet.

Wage increases |  |  | 5.00 | % |  |  | 5.00 | % |  |  | 5.00 | %

1. |  | Effect of a one-percent change: Discount rate: $26 million change in ABO and $1 million change in pension cost; Return on plan assets: $2 million change in pension cost.

Pension plan assets, which consist primarily of fixed-income and equity securities, are valued using current market quotations. Plan obligations and the annual pension expense are determined on an actuarial basis and are affected by numerous assumptions and estimates including the market value of plan assets, estimates of the expected return on plan assets, discount rates, future wage increases and other assumptions. The discount rate, assumed rate of return on plan assets and wage increases are the assumptions that generally have the most significant impact on our pension cost and obligation.
The discount rate for benefit obligation and pension cost purposes is the rate at which the pension obligation could be effectively settled. This rate was developed by matching the cash flows underlying the pension obligation with a spot rate curve based on the actual returns available on high-grade (Moody’s Aa) US corporate bonds. Bonds included in this analysis were restricted to those with a minimum outstanding balance of $50 million. Only non-callable bonds, or bonds with a make-whole provision, were included. Finally, outlying bonds (highest and lowest 10%) were discarded as being non-representative and likely to be subject to a change in investment grade. The resulting discount rate from this analysis was rounded to the nearest 25 basis points. The procedure was applied separately for pension and post-retirement welfare plan purposes, and produced the same rate in each case.
The assumed rate of return on assets for pension cost purposes is the weighted average of expected long-term asset return assumptions. In estimating the long-term rate of return for plan assets, historical markets are studied and long-term historical returns on equities and fixed-income investments reflect the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors such as inflation and the interest rates are evaluated before long-term capital market assumptions are finalized.
Wage increases reflect the best estimate of merit increases to be provided, consistent with assumed inflation rates.
e) Other Post-retirement Benefits
We provide post-retirement medical, dental, and life insurance benefits to certain employees. We use the corridor approach in the accounting for post-retirement benefits. Actuarial gains and losses resulting from variances between actual results and economic estimates or actuarial assumptions are deferred and amortized over the average remaining life expectancy of participants when the net gains or losses exceed 10% of the accumulated post-retirement benefit obligation.

We have assumed a health care cost trend of 10% in 2006, decreasing ratability to 5% in 2011 and thereafter. The assumed health care cost trend had a minimal effect on the amounts reported. A one percentage point change in the assumed health care cost trend rate at December 31, 2005 would have increased the post-retirement obligation by $4 million or decreased the post-retirement benefit obligation by $4 million and would have had no significant effect on the benefit expense for 2005.

24 n Litigation and Claims
Certain conditions may exist as of the date the financial statements are issued, which may result in a loss to the Company but which will only be resolved when one or more future events occur or fail to occur. In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in such proceedings, the Company and its legal counsel evaluate the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought.
If the assessment of a contingency suggests that a loss is probable, and the amount can be reliably estimated, then a loss is recorded. When a contingent loss is not probable but is reasonably possible, or is probable but the amount of loss cannot be reliably estimated, then details of the contingent loss are disclosed. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case we disclose the nature of the guarantee. Legal fees incurred in connection with pending legal proceedings are expensed as incurred.
Wagner complaint
On June 12, 2003, a complaint was filed against Barrick and several of its current or former officers in the US District Court for the Southern District of New York. The complaint is on behalf of Barrick shareholders who purchased Barrick shares between February 14, 2002 and September 26, 2002. It alleges that Barrick and the individual defendants violated US securities laws by making false and misleading statements concerning Barrick’s projected operating results and earnings in 2002. The complaint seeks an unspecified amount of damages. Other parties on behalf of the same proposed class of Barrick shareholders filed several other complaints, making the same basic allegations against the same defendants. In September 2003, the cases were consolidated into a single action in the Southern District of New York. The plaintiffs filed a Consolidated and/or Amended Complaint on November 5, 2003. On January 14, 2004, Barrick filed a motion to dismiss the complaint. On September 29, 2004, the Court issued an order granting in part and denying in part Barrick’s motion to dismiss the action. The Court granted the plaintiffs leave to file a Second Amended Complaint, which was filed on October 20, 2004.

On January 31, 2006, the Court issued an order granting in part and denying in part Barrick’s motion to dismiss. We intend to defend the action vigorously.
Wilcox complaint
On September 8, 2004, two of our US subsidiaries, Homestake Mining Company of California (“Homestake California”) and Homestake Mining Company (“Homestake”) were served with a First Amended Complaint by persons alleging to be current or former residents of a rural area near the former Grants Uranium Mill. The Complaint, which was filed in the US District Court for the District of New Mexico, identifies 26 plaintiffs. Homestake and Homestake California, along with an unspecified number of unidentified defendants, are named as defendants. The plaintiffs allege that they have suffered a variety of physical, emotional and financial injuries as a result of exposure to radioactive and other hazardous substances. The Complaint seeks an unspecified amount of damages. On November 25, 2005, the Court issued an order granting in part and denying in part a motion to dismiss the claim. The Court granted the motion and dismissed plaintiffs’ claims based on strict and absolute liability and ruled that plaintiffs’ state law claims are pre-empted by the Price-Anderson Act. An Initial Scheduling Order has been issued by the Court. We intend to defend the action vigorously.

Gold Mineral Reserves and Mineral Resources
The table on the next page sets forth Barrick’s interest in the total proven and probable gold mineral reserves at each property. For further details of proven and probable mineral reserves and measured, indicated and inferred mineral resources by category, see pages 127 and 128.
The Company has carefully prepared and verified the mineral reserve and mineral resource figures and believes that its method of estimating mineral reserves has been verified by mining experience. These figures are estimates, however, and no assurance can be given that the indicated quantities of gold will be produced. Gold price fluctuations may render mineral reserves containing relatively lower grades of gold mineralization uneconomic. Moreover, short-term operating factors relating to the mineral reserves, such as the need for orderly development of ore bodies or the processing of new or different ore grades, could affect the Company’s profitability in any particular accounting period.
Definitions
A mineral resource is a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilized organic material including base and precious metals, coal, and industrial minerals in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral resources are sub-divided, in order of increasing geological confidence, into inferred, indicated and measured categories.
An inferred mineral resource is that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.
An indicated mineral resource is that part of a mineral resource for which quantity, grade and quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.
A measured mineral resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.
Mineral resources, which are not mineral reserves, do not have demonstrated economic viability.
A mineral reserve is the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A mineral reserve includes diluting materials and allowances for losses that may occur when the material is mined. Mineral reserves are sub-divided in order of increasing confidence into probable mineral reserves and proven mineral reserves.
A probable mineral reserve is the economically mineable part of an indicated and, in some circumstances, a measured mineral resource demonstrated by a least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.
A proven mineral reserve is the economically mineable part of a measured mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.

1. |  | Mineral reserves (“reserves”) have been calculated as at December 31, 2005 in accordance with National Instrument 43-101 as required by Canadian securities regulatory authorities. For United States reporting purposes, Industry Guide 7, (under the Securities and Exchange Act of 1934), as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. Accordingly, for US reporting purposes, Buzwagi is classified as mineralized material. Barrick is currently assessing the implications of conditions contained in the resolution issued by Chilean regulatory authorities approving the environmental impact assessment for the Pascua-Lama project. It is possible that following the completion of such assessment, up to 1 million ounces of mineralization at the Pascua-Lama project may be reclassified from reserves to mineralized material for US reporting purposes. Calculations have been prepared by employees of Barrick under the supervision of Jacques McMullen, Corporate Head, Metallurgy and Process Development of Barrick, Rick Allan, Director — Engineering and Mining Support of Barrick, and Rick Sims, Manager Corporate Reserves of Barrick. Reserves have been calculated using an assumed long-term average gold price of $US400 (Aus$560), a silver price of US$6.25 and exchange rates of $1.30 $Can/$US and $0.72 $US/$Aus. Reserves at the Hemlo and Eskay properties assumed a gold price of $US425. Reserves at the Hemlo property assumed an exchange rate of $1.20 $Can/$US. Reserve calculations incorporate current and/or expected mine plans and cost levels at each property. Varying cut-off grades have been used depending on the mine and type of ore contained in the reserves. Barrick’s normal data verification procedures have been employed in connection with the calculations. For a more detailed description of the key assumptions, parameters and methods used in calculating Barrick’s reserves and resources, see Barrick’s most recent Annual Information Form on file with Canadian provincial securities regulatory authorities and the US Securities and Exchange Commission.

Corporate Governance and Committees of the Board
Corporate Governance
Over the past several years, there has been an increased focus on corporate governance in both the United States and Canada. Among other regulatory initiatives, the New York Stock Exchange added corporate governance standards to its listing rules. Although, as a regulatory matter, the vast majority of the NYSE corporate governance standards are not directly applicable to Barrick as a Canadian company, Barrick has implemented a number of structures and procedures to comply with the NYSE standards. There are no significant differences between Barrick’s corporate governance practices and the NYSE standards applicable to U.S. companies.
The Board of Directors has approved a set of Corporate Governance Guidelines to promote the effective functioning of the Board of Directors and its Committees and to set forth a common set of expectations as to how the Board should manage its affairs and perform its responsibilities. Barrick has also adopted a Code of Business Conduct and Ethics that is applicable to all directors, officers and employees of Barrick. In conjunction with the adoption of the Code, Barrick established a toll-free compliance hotline to allow for anonymous reporting of any suspected Code violations, including concerns regarding accounting, internal accounting controls or other auditing matters. A copy of the Corporate Governance Guidelines, the Code of Business Conduct and Ethics and the mandates of the Board of Directors and each of the Committees of the Board, including the Audit Committee, the Compensation Committee and the Corporate Governance and Nominating Committee, is posted on Barrick’s website at www.barrick.com and is available in print from the Company to any shareholder upon request.

(M.A. Cohen, P.C. Godsoe, A.A. MacNaughton)

The Committee is responsible for reviewing and recommending director and senior management compensation and for succession planning with respect to senior executives.

Cautionary Statement on Forward-Looking Information
Certain information contained or incorporated by reference in this Annual Report 2005, including any information as to our future financial or operating performance, constitutes “forward-looking statements”. All statements, other than statements of historical fact, are forward-looking statements. The words “believe”, “expect”, “anticipate”, “contemplate”, “target”, “plan”, “intends”, “continue”, “budget”, “estimate”, “may”, “will”, “schedule” and similar expressions identify forward-looking statements. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by us, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements. Such factors include, but are not limited to: fluctuations in the currency markets (such as the Canadian and Australian dollars versus the US dollar); fluctuations in the spot and forward price of gold or certain other commodities (such as silver, copper, diesel fuel and electricity); changes in US dollar interest rates or gold lease rates that could impact the mark-to-market value of outstanding derivative instruments and ongoing payments/receipts under interest rate swaps and variable rate debt obligations; risks arising from holding derivative instruments (such as credit risk, market liquidity risk and mark-to-market risk); changes in national and local government legislation, taxation, controls, regulations and political or economic developments in Canada, the United States, Dominican Republic, Australia, Papua New Guinea, Chile, Peru, Argentina, South Africa, Tanzania, Russia or Barbados or other countries in which we do or may carry on business in the future; business opportunities that may be presented to, or pursued by, us; our ability to successfully integrate acquisitions, including our recent acquisition of Placer Dome; operating or technical difficulties in connection with mining or development activities; the speculative nature of gold exploration and development, including the risks of obtaining necessary licenses and permits; diminishing quantities or grades of reserves; adverse changes in our credit rating; and contests over title to properties, particularly title to undeveloped properties. In addition, there are risks and hazards associated with the business of gold exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance, or inability to obtain insurance, to cover these risks). Many of these uncertainties and contingencies can affect our actual results and could cause actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, us. Readers are cautioned that forward-looking statements are not guarantees of future performance. All of the forward-looking statements made in this Annual Report 2005 are qualified by these cautionary statements. Specific reference is made to Barrick’s most recent Form 40-F/Annual Information Form on file with the SEC and Canadian provincial securities regulatory authorities for a discussion of some of the factors underlying forward-looking statements.
We disclaim any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise, except to the extent required by applicable laws.
