2010 Annual Report

To Our Shareholders

The theme of this annual report, “Connecting the World,” highlights Freeport-McMoRan Copper & Gold’s significant role in producing metals that are vital to the world’s economies. In particular, copper, which generated 78 percent of our 2010 revenues, is critical in connecting the world through a broad range of applications, including infrastructure development, Tenke Fungurume, power systems, transportation, industrial applications Democratic Republic of Congo and a variety of energy-saving devices. We are a global leader in the production of copper, gold and molybdenum and have a long and successful history of Grasberg, Indonesia conducting our business in a safe, highly efficient and socially responsible manner for the benefit of our stakeholders.

2010 was an outstanding year for our company. After successfully managing through one of the most severe economic downturns in history, we achieved in 2010 the best financial results in our company’s history. Our global team performed at an exceptional level and achieved a number of safety and operational records. We were also successful in achieving a significant increase in our mineral reserves, which provide building blocks of future growth. Our copper business benefited from strong demand from China and emerging markets, recovering economic conditions in the United States, Europe and Japan — and limited supplies. 4 FREEPORT-McMoRan COPPER & GOLD INC. 2010 Annual Report early shareholders.

Operational Overview 2010 Annual Report Annual 2010

Africa FCX operates the Tenke Fungurume copper and cobalt mine in the Katanga province of the Democratic Republic of Congo (DRC). FCX is engaged in drilling activities, exploration analyses and metallurgical testing to evaluate the potential of the highly prospective minerals district at Tenke Fungurume. These analyses are being incorporated in future plans to evaluate opportunities for expansion. FCX is planning a second phase of the project, which would include optimizing the current plant and increasing capacity. Future expansions are subject to

FREEPORT-McMoRan COPPER & GOLD INC. a number of factors, including economic and market conditions and the business and investment climate in the DRC.

Consolidated sales from Tenke Fungurume increased to 262 million pounds of copper in 2010, compared with 130 million pounds of copper in 2009, reflecting higher operating rates and a full year of production in 2010. Consolidated cobalt sales totaled 20 million pounds in 2010. FCX expects Tenke Fungurume sales of approximately 285 million pounds of copper and over 20 million pounds of cobalt in 2011.

In October 2010, the government of the DRC announced the conclusion of the review of Tenke Fungurume Mining’s (TFM) contracts, and confirmed that TFM’s existing mining contracts are in good standing and acknowledged the rights and benefits granted under those contracts. In connection with the review, TFM made several commitments that have been reflected in amendments to its mining contracts.

FCX is pursuing many opportunities in the highly prospective Tenke Fungurume minerals district (above) in the Democratic Republic of Congo, in the heart of the African Copper Belt.

Our milling (above) and processing (large photo) facilities at Tenke Fungurume performed above design capacity in 2010.

Copper is core to a variety of energy-saving devices, including hybrid and electric vehicles (left), which require two to three times more copper than the average gas-engine automobile.

16

We were successful in achieving a significant increase in our mineral reserves, and exploration will continue to drive our future plans. As we seek new metals deposits around the world, we are primarily focused on the proven rich areas near our existing operations. (pictured: exploration drilling near the Morenci mine in Arizona).

Reserves and Mineralized Material

As of December 31, 2010, FCX’s estimate of consolidated recoverable proven and probable reserves totaled 120.5 billion pounds of copper, 35.5 million ounces of gold and 3.39 billion pounds of molybdenum. Net reserve additions of 20.2 billion pounds of copper and 0.87 billion pounds of molybdenum replaced approximately 5 times FCX’s 2010 copper production and approximately 12 times FCX’s 2010 molybdenum production. Estimated recoverable reserves were determined using long-term average prices of $2.00 per pound for copper, $750 per ounce for gold and $10.00 per pound for molybdenum.

At December 31, 2010, in addition to the estimated proven and probable reserves, FCX identified estimated mineralized material (assessed using a long-term average price of $2.20 per pound for copper) with incremental contained copper of 110 billion pounds. FCX continues to pursue aggressively opportunities to convert this mineralized material into reserves, future production volumes and cash flow.

Sustainable Development

FCX directly contributes to a sustainable future by providing metals that literally connect the world’s infrastructure. As a leading international mining company, FCX understands the importance of producing these metals in a safe and socially responsible manner. As the earth’s population continues to grow along with the global standard of living, FCX expects the demand for its metals to similarly increase. This will challenge our ability to reduce or mitigate certain impacts, such as greenhouse gas emissions and water consumption, as production expands. FCX evaluates opportunities to minimize environmental impacts and to be a catalyst for sustainability in communities where it operates. Guiding FCX in meeting this challenge is the International Council on Mining and Metals (ICMM). As a founding member, FCX endorses the ICMM’s Sustainable Development Framework, including its 10 Sustainable Development Principles. In addition, FCX has established and reports against its progress on company-wide sustainable development performance targets that address issues identified by internal and external stakeholders. FCX reports its sustainability performance according to the Global Reporting Initiative and FCX’s 2010 Working Toward Sustainable Development report will be available on FCX’s website at www.fcx.com upon completion of third-party assurance. 18 FREEPORT-McMoRan COPPER & GOLD INC. 2010 Annual Report BOARD COMMITTEES: COMMITTEES: BOARD Chief FinancialOfficerand Treasurer Executive Vice President, Kathleen L.Quirk Chief AdministrativeOfficer Executive Vice Presidentand Michael J.Arnold President andChiefExecutiveOfficer Richard C.Adkerson Chairman oftheBoard James R.Moffett MANAGEMENT 4 3 2 1 Board ofDirectorsandManagement H.

2010 compared with 2009. At the , the sequencing in mining areas with varying ore grades causes fluctuations in the timing of ore production resulting in varying quarterly and annual sales of copper and gold. PT Freeport Indonesia’s share of sales decreased to 1.2 billion pounds of copper and 1.8 million ounces of gold in 2010, compared with 1.4 billion pounds of copper and 2.5 million ounces of gold in 2009. Anticipated changes in ore grades FREEPORT-McMoRan COPPER & GOLD INC. & GOLD COPPER FREEPORT-McMoRan throughout the year resulted in significant variability in quarterly volumes during 2010. Lower copper and gold sales volumes in 2010 primarily reflect mining in a lower grade section of the Grasberg open pit during the first half of 2010. We expect to mine in a lower grade section of the Grasberg open pit during 2011. As a result, PT Freeport Indonesia’s projected sales of 1.0 billion pounds of copper and 1.3 million ounces of gold for 2011 are lower than 2010 volumes. Ore grades and copper and gold sales volumes are expected to be higher in the second half of 2011, compared with the first half, with approximately 53 percent

Represents contractual obligations for purchases of goods or services that are defined by us as agreements that are enforceable and legally binding and that specify all significant terms. Take-or-pay contracts primarily comprise the procurement of copper concentrates and cathodes ($2.1 billion), transportation ($201 million), electricity ($144 million) and oxygen ($143 million). Some of our take-or-pay contracts are settled based on the prevailing market rate for the service or commodity purchased, and in some cases, the amount of the actual obligation may change over time because of market conditions. Obligations for copper concentrates and cathodes provide for deliveries of specified volumes, at market-based prices, primarily to Atlantic Copper and the North America copper mines. Transportation obligations are primarily for South America contracted ocean freight rates and for North America natural gas transportation. Electricity obligations are primarily for contractual minimum demand at the South America and Tenke mines. Oxygen obligations provide for deliveries of specified volumes, at fixed prices, primarily to Atlantic Copper. d. In August 2002, Atlantic Copper complied with Spanish legislation by agreeing to fund 7.2 million euros annually for 15 years to an approved insurance company for an estimated 72 million euro contractual obligation to supplement amounts paid to certain retired employees.

FCX has organized its operations into five primary divisions — North America copper mines, South America mining, Indonesia mining, Africa mining and Molybdenum operations. Notwithstanding this structure, FCX internally reports information on a mine-by-mine basis. Therefore, FCX concluded that its operating segments include individual mines. Operating segments that meet certain thresholds are reportable segments. Further discussion of the reportable primary operating divisions, as well segments included in FCX’s Atlantic and other reportable segments — Rod & Refining FCX’s as Copper Smelting & Refining — follows.

Recoverable Proven and Probable Reserves

(billion pounds)

b c NOTES TO CONSOLIDATED FINANCIAL STATEMENTS FINANCIAL CONSOLIDATED NOTES TO Recoverable proven and probable reserves are estimated metal quantities from which FCX expects to be paid after application of estimated metallurgical recovery rates and smelter recovery rates, where applicable. Recoverable reserves are that part of a mineral deposit that FCX estimates can be economically and legally extracted or produced at the time of the reserve determination. Consolidated basis reserves represent estimated metal quantities after reduction for joint venture partner interests at the Morenci mine in North America and the Grasberg minerals district in Indonesia. Excluded from the table above are FCX’s estimated recoverable proven and probable reserves for cobalt and silver totaling 0.75 billion pounds of cobalt at Tenke Fungurume and 325.0 million ounces of silver throughout the world. Net equity interest reserves represent estimated consolidated basis metal quantities further reduced for noncontrolling interest ownership. Excluded from the table above are FCX’s estimated recoverable proven and probable reserves for cobalt and silver totaling 0.43 billion pounds of cobalt at Tenke Fungurume and 270.0 million ounces of silver throughout the world.

Estimated recoverable reserves at December 31, 2010, were 31, 2010, were Estimated recoverable reserves at December determined of $2.00 per pound for using long-term average prices for molybdenum, $750 per ounce for gold, $10.00 per pound copper, pound for cobalt,$15.00 per ounce for silver and $10.00 per per ounce for $550 compared with $1.60 per pound for copper, per ounce for silvergold, $8.00 per pound for molybdenum, $12.00 used to determineand $10.00 per pound for cobalt that were 31, 2009. For the estimated recoverable reserves at December three pricesyears ended December 31, 2010, the LME spot copper prices averaged averaged $2.97 per pound, the London gold $1,023 and the weekly average price for molybdenumper ounce averaged $18.76 per pound. quoted by Metals Week North America South America Indonesia Africa Consolidated basis Net equity interest a. b. c.
