Consolidated Sales Volumes

Fourth-quarter2013 consolidated copper sales of 1.14 billion pounds were higher than fourth-quarter2012 sales of 972 million pounds reflecting improved volumes throughout FCX's global mining operations. Higher fourth-quarter2013 sales, compared to the October 2013 estimate of 1.1 billion pounds, primarily reflected higher volumes from South America and Indonesia. Fourth-quarter2013 consolidated gold sales of 512 thousand ounces were higher than fourth-quarter2012 sales of 254 thousand ounces and the October 2013 estimate of 390 thousand ounces reflecting higher ore grades and improved operating performance in Indonesia. Fourth-quarter2013 consolidated molybdenum sales of 22 million pounds were higher than fourth-quarter2012 sales of 21 million pounds and the October 2013 estimate of 21 million pounds.

Fourth-quarter2013 sales from oil and gas operations of 16.6 MMBOE, including 11.7 million barrels (MMBbls) of crude oil, 22.9 billion cubic feet (Bcf) of natural gas and 1.1 MMBbls of natural gas liquids (NGLs), were higher than the October 2013 estimate of 16 MMBOE primarily reflecting higher Eagle Ford production.

Consolidated sales for the year 2014 are expected to approximate 4.4 billion pounds of copper, 1.7 million ounces of gold, 95 million pounds of molybdenum and 60.7 MMBOE, including 1.0 billion pounds of copper, 325 thousand ounces of gold, 25 million pounds of molybdenum and 15.3 MMBOE in first-quarter2014.

In January 2014, the Indonesian government published regulations regarding exports of minerals, including copper concentrates. The regulations provide that holders of contracts of work with existing processing facilities in Indonesia may continue to export product through January 12, 2017, but establish new requirements, including new export duties, for the continued export of copper concentrates. The regulations conflict with PT Freeport Indonesia's (PT-FI) Contract of Work (COW) and PT-FI is working with the Indonesian government to clarify the situation and to defend its rights under the COW. Refer to Indonesia Mining beginning on page 7 for further discussion.

FCX’s 2014 copper and gold sales estimates presented above assume no changes to PT-FI’s planned 2014 concentrate shipments. As a result of the delay in obtaining administrative approvals for 2014 exports, associated with the new regulations, PT-FI is implementing near-term changes to its operations to coordinate its concentrate production with PT Smelting's operating plans. These changes will result in the deferral of an estimated 40 million pounds of copper and 80 thousand ounces of gold per month pending resolution of these matters. FCX will update its 2014 outlook as export approvals are obtained.

Consolidated Unit Costs

Mining Unit Net Cash Costs. Consolidated average unit net cash costs (net of by-product credits) for FCX's copper mines of $1.16 per pound of copper in fourth-quarter2013 were significantly lower than unit net cash costs of $1.54 per pound in fourth-quarter2012 and the previous estimate of $1.46 per pound primarily reflecting higher copper and gold sales volumes and ongoing cost control efforts. For the year 2013, consolidated unit net cash costs (net of by-product credits) averaged $1.49 per pound of copper compared with the year 2012 average of $1.48 per pound.

Assuming average prices of $1,200 per ounce of gold and $9.50 per pound of molybdenum and achievement of current sales volume and cost estimates, consolidated unit net cash costs (net of by-product credits) for FCX's copper mining operations are expected to average $1.45 per pound of copper for the year 2014. Quarterly unit net cash costs vary with fluctuations in sales volumes and average realized prices (primarily gold and molybdenum prices). Unit net cash costs are expected to decline in 2014, compared to the 2013 average, as FCX gains access to higher grade ore in Indonesia. The impact of price changes on 2014 consolidated unit net cash costs would approximate $0.02 per pound for each $50 per ounce change in the average price of gold and $0.02 per pound for each $2 per pound change in the average price of molybdenum.

Freeport-McMoRan Copper & Gold4

Oil and Gas Cash Production Costs per BOE. Cash production costs for oil and gas operations were $17.63 per BOE in fourth-quarter2013 and $17.14 per BOE for the seven month period in 2013 following the acquisition date. Based on current sales volume and cost estimates, cash production costs per BOE are expected to approximate $20 per BOE for the year 2014.

MINING OPERATIONS

North America Copper Mines. FCX operates seven open-pit copper mines in North America - Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. All of the North America mining operations are wholly owned, except for Morenci. FCX records its 85 percent joint venture interest in Morenci using the proportionate consolidation method. In addition to copper, the Sierrita, Bagdad, Morenci and Chino mines also produce molybdenum concentrates.

Operating and Development Activities. FCX has increased production from its North America copper mines in recent years and continues to evaluate a number of opportunities to invest in additional production capacity following positive exploration results. Future investments will be undertaken based on the results of economic and technical feasibility studies and market conditions.

At Morenci, FCX is expanding mining and milling capacity to process additional sulfide ores identified through exploratory drilling. The project is targeting incremental annual production of approximately 225 million pounds of copper in 2014 (an approximate 40 percent increase from 2013) through an increase in milling rates from 50,000 metric tons of ore per day to approximately 115,000 metric tons of ore per day. At full rates, Morenci's copper production is expected to approach 1 billion pounds in 2015 compared with 564 million pounds in 2013. Construction is more than 60 percent complete and the project is on track for completion in the first half of 2014. At December 31, 2013, approximately $1.0 billion had been incurred for this project, with approximately $0.6 billion remaining to be incurred.

Operating Data. Following is summary consolidated operating data for the North America copper mines for the fourth quarters and years ended2013 and 2012:

b. For a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in FCX's consolidated financial statements, refer to the supplemental schedule, "Product Revenues and Production Costs," beginning on page XIII, which is available on FCX's website, "www.fcx.com."

North America's consolidated copper sales volumes of 334 million pounds in fourth-quarter2013 were higher than fourth-quarter2012 sales of 321 million pounds primarily reflecting higher ore grades and recovery rates. Sales from the North America copper mines are expected to approximate 1.73 billion pounds of copper for the year 2014, compared with 1.42 billion pounds of copper in 2013, primarily reflecting higher production from Morenci following the completion of the mill expansion project.

Freeport-McMoRan Copper & Gold5

Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.82 per pound of copper in fourth-quarter2013 were higher than unit net cash costs of $1.78 per pound in fourth-quarter2012, primarily reflecting lower molybdenum credits, partly offset by higher copper sales volumes. Average unit net cash costs (net of by-product credits) for the North America copper mines are expected to approximate $1.76 per pound of copper for the year 2014, based on current sales volume and cost estimates and assuming an average molybdenum price of $9.50 per pound. North America's average unit net cash costs for 2014 would change by approximately $0.04 per pound for each $2 per pound change in the average price of molybdenum.

South America Mining. FCX operates four copper mines in South America - Cerro Verde in Peru and El Abra, Candelaria and Ojos del Salado in Chile. FCX owns a 53.56 percent interest in Cerro Verde, a 51 percent interest in El Abra, and an 80 percent interest in the Candelaria and Ojos del Salado mining complex. All operations in South America are consolidated in FCX's financial statements. In addition to copper, the Candelaria and Ojos del Salado mines produce gold and silver, and the Cerro Verde mine produces molybdenum concentrates.

Development Activities. Construction activities associated with a large-scale expansion at Cerro Verde are in progress. Engineering is more than 90 percent complete and construction progress is advancing on schedule. The project will expand the concentrator facilities from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day and provide incremental annual production of approximately 600 million pounds of copper and 15 million pounds of molybdenum beginning in 2016. At December 31, 2013, approximately $1.5 billion had been incurred for this project, with approximately $3.1 billion remaining to be incurred.

FCX continues to evaluate a potential large-scale milling operation at El Abra to process additional sulfide material and to achieve higher recoveries. Exploration results in recent years at El Abra indicate a significant sulfide resource, which could potentially support a major mill project. Future investments will be dependent on technical studies, economic factors and global copper market conditions.

Freeport-McMoRan Copper & Gold6

c. The 2013 periods includes charges of $36 million ($0.09 per pound of copper for fourth-quarter and $0.03 per pound for the year) associated with new labor agreements at Cerro Verde, and the 2012 periods includes charges of $16 million ($0.04 per pound of copper for fourth-quarter and $0.01 per pound for the year) associated with new labor agreements at Candelaria.

South America's consolidated copper sales volumes of 402 million pounds in fourth-quarter2013 were higher than fourth-quarter2012 sales of 350 million pounds primarily reflecting higher ore grades at Candelaria and timing of shipments. Sales from South America mining are expected to approximate 1.2 billion pounds of copper for the year 2014, compared with sales of 1.33 billion pounds of copper in 2013, primarily reflecting lower ore grades at Candelaria and Cerro Verde.

Average unit net cash costs (net of by-product credits) for South America mining of $1.30 per pound of copper in fourth-quarter2013 were lower than unit net cash costs of $1.54 per pound in fourth-quarter2012, primarily reflecting higher volumes and lower energy costs. Average unit net cash costs (net of by-product credits) for South America mining are expected to approximate $1.61 per pound of copper for the year 2014, based on current sales volume and cost estimates and assuming average prices of $1,200 per ounce of gold and $9.50 per pound of molybdenum. Higher average unit net cash costs in 2014 are primarily related to lower volumes.

During fourth-quarter 2013, Cerro Verde signed a new four-year Collective Labor Agreement, which is effective beginning September 1, 2014, upon the expiration of the current agreement.

Indonesia Mining. Through its 90.64 percent owned and consolidated subsidiary PT-FI, FCX's assets include one of the world's largest copper and gold deposits at the Grasberg minerals district in Papua, Indonesia. PT-FI operates a proportionately consolidated joint venture, which produces copper concentrates that contain significant quantities of gold and silver.    

Development Activities. FCX has several projects in progress in the Grasberg minerals district related to the development of large-scale, long-lived, high-grade underground ore bodies. In aggregate, these underground ore bodies are expected to ramp up over several years to produce approximately 240,000 metric tons of ore per day following the transition from the Grasberg open pit, currently anticipated to occur in 2017. Development of the Grasberg Block Cave and Deep Mill Level Zone (DMLZ) mines is advancing to enable DMLZ to commence production in 2015 and the Grasberg Block Cave mine to commence production in 2017. Over the next five years, estimated aggregate capital spending on these projects is currently expected to average $0.9 billion per year ($0.7 billion per year net to PT-FI).

Regulatory Matters.In January 2014, the Indonesian government published regulations regarding exports of minerals, including copper concentrates. The regulations provide that holders of contracts of work with existing processing facilities in Indonesia may continue to export product through January 12, 2017, but establish new requirements for the continued export of copper concentrates, including the imposition of a new progressive export duty on copper concentrates in the amount of 25 percent in 2014, rising to 60 percent by mid-2016.

PT-FI’s COW, which has a primary term through 2021 and allows for two 10-year extensions through 2041 (subject to approval by the Indonesian government, which cannot be withheld or delayed unreasonably), authorizes it to export concentrates and sets forth the taxes and other fiscal terms applicable to its operations. The COW states that PT-FI shall not be subject to taxes, duties or fees subsequently imposed or approved by the Indonesian government except as expressly provided in the COW.

The January 2014 regulations conflict with PT-FI’s contractual rights, and FCX and PT-FI are working with the Indonesian government to clarify the situation and to defend PT-FI's rights under the COW.  PT-FI is also seeking to obtain its administrative permits for 2014 exports, which are currently pending and have been delayed as a result of the new regulations.

PT-FI has complied with the Indonesian government’s requirements on local processing in its COW, which enabled the construction and commissioning in 1998 of the first copper smelter in Indonesia, PT Smelting, an affiliate of PT-FI. During 2014, approximately 40 percent of PT-FI’s production is expected to be shipped to PT Smelting, with the balance of its concentrates expected to be sold pursuant to long-term contracts with other international smelters.

PT-FI's 2014 copper and gold sales estimates presented below assume no changes to planned 2014 concentrate shipments. As a result of the delay in obtaining its administrative approval for 2014 exports, associated with the new regulations, PT-FI is implementing near-term changes to its operations to coordinate its concentrate

production with PT Smelting’s operating plans. These changes will result in the deferral of an estimated 40 million pounds of copper and 80 thousand ounces of gold per month pending resolution of these matters. FCX will update its 2014 outlook as export approvals are obtained.

Indonesia's fourth-quarter2013 copper sales of 292 million pounds and gold sales of 476 thousand ounces were significantly higher than fourth-quarter2012 copper sales of 204 million pounds and gold sales of 224 thousand ounces and above October 2013 estimates resulting primarily from higher ore grades and increased mill rates and recoveries. Results benefited from strong productivity throughout the open pit and underground mining operations and milling operations. During fourth-quarter2013, the Deep Ore Zone underground mine's rates averaged 59,900 metric tons of ore per day and are expected to reach 80,000 metric tons of ore per day by mid-2014.

At the Grasberg mine, the sequencing of mining areas with varying ore grades causes fluctuations in quarterly and annual production of copper and gold. Sales from Indonesia mining are expected to approximate 1.1 billion pounds of copper and 1.6 million ounces of gold for the year 2014, compared with 885 million pounds of copper and 1.1 million ounces of gold for the year 2013. Sales from Indonesia mining are expected to increase in 2014 through 2016 as PT-FI gains access to higher grade ore. PT-FI's estimated sales volumes are subject to change depending on timing of resolution of export matters as described above.

A significant portion of PT-FI's costs are fixed and unit costs vary depending on production volumes. Indonesia's unit net cash costs (including gold and silver credits) of $0.21 per pound of copper in fourth-quarter2013 were lower than unit net cash costs of $1.33 per pound in fourth-quarter2012 reflecting significantly higher volumes and lower operating costs.

Unit net cash costs (net of gold and silver credits) for Indonesia mining are expected to approximate $0.81 per pound of copper for the year 2014, based on current sales volume and cost estimates and assuming an average gold price of $1,200 per ounce. Indonesia mining's projected unit net cash costs would change by approximately $0.075 per pound for each $50 per ounce change in the average price of gold. Because of the fixed nature of a large portion of Indonesia's costs, unit costs vary from quarter to quarter depending on copper and gold volumes.

Africa Mining. Through its 56 percent owned and consolidated subsidiary Tenke Fungurume Mining S.A.R.L. (TFM), FCX operates in the Tenke Fungurume (Tenke) minerals district in the Katanga province of the Democratic Republic of Congo (DRC). In addition to copper, the Tenke mine produces cobalt hydroxide.

Operating and Development Activities.TFM completed its second phase expansion project in early 2013, which included optimizing the current plant and increasing mine, mill and processing capacity. The expanded mill facility is performing well, with throughput rates averaging 14,900 metric tons of ore per day during 2013, compared with original design capacity of 14,000 metric tons of ore per day, enabling an increase in Tenke's copper production to over 430 million pounds per year. The addition of a second sulphuric acid plant is expected to be completed in 2016.

FCX continues to engage in exploration activities and metallurgical testing to evaluate the potential of the highly prospective minerals district at Tenke. These analyses are being incorporated in future plans for potential expansions of production capacity. Future expansions are subject to a number of factors, including economic and market conditions, and the business and investment climate in the DRC.

c. Net of cobalt downstream processing and freight costs.

TFM's copper sales of 112 million pounds in fourth-quarter2013 were higher than fourth-quarter2012 copper sales of 97 million pounds, primarily reflecting increased mining and milling rates and higher ore grades. TFM's sales are expected to approximate 445 million pounds of copper and 30 million pounds of cobalt for the year 2014, compared with 454 million pounds of copper and 25 million pounds of cobalt for the year 2013.

During the second half of 2013, TFM experienced power interruptions, which impacted operating rates. Power availability improved during the fourth quarter. TFM continues to work with its power provider and DRC authorities to establish more consistent and reliable power availability.

TFM's unit net cash costs (net of cobalt credits) of $1.14 per pound of copper in fourth-quarter2013 were lower than unit net cash costs of $1.24 per pound in fourth-quarter2012 primarily reflecting higher cobalt credits. Unit net cash costs (net of cobalt credits) for TFM are expected to approximate $1.28 per pound of copper for the year 2014, based on current sales volume and cost estimates and assuming an average cobalt price of $12 per

Freeport-McMoRan Copper & Gold9

pound. TFM's projected unit net cash costs for 2014 would change by approximately $0.08 per pound for each $2 per pound change in the average price of cobalt.

Molybdenum Mines. FCX has two wholly owned molybdenum mines in North America - the Henderson underground mine and the Climax open-pit mine, both in Colorado. The Henderson and Climax mines produce high-purity, chemical-grade molybdenum concentrates, which are typically further processed into value-added molybdenum chemical products.

Operating Data. Following is summary consolidated operating data for the molybdenum mines for the fourth quarters and years ended2013 and 2012:

	Three Months Ended				Years Ended
	December 31,				December 31,

a. Refer to summary operating data on page 3 for FCX's consolidated molybdenum sales, which includes sales of molybdenum produced at the molybdenum mines, and from the North and South America copper mines.

b. Includes molybdenum production from the Climax mine since the start of commercial operations in May 2012.

c. Unit net cash costs per pound of molybdenum for the 2013 periods reflect the results of the Henderson and Climax mines, and the 2012 periods reflect the results of only the Henderson mine as startup activities were still underway for the Climax mine. For a reconciliation of unit net cash costs per pound to production and delivery costs applicable to sales reported in FCX's consolidated financial statements, refer to the supplemental schedule, "Product Revenues and Production Costs," beginning on page XIII, which is available on FCX's website, "www.fcx.com."

Market conditions for molybdenum declined in 2013 resulting from weak demand in the metallurgical sector and increased supply. FCX continues to monitor market conditions and adjusts its primary molybdenum production as market conditions warrant.

Based on current sales volume and cost estimates, unit net cash costs for the molybdenum mines are expected to average approximately $7.25 per pound of molybdenum for the year 2014.

Mining Exploration Activities.FCX is actively conducting exploration activities near its existing mines with a focus on opportunities to expand reserves and resources to support development of additional future production capacity in the large minerals districts where it currently operates. Exploration results indicate opportunities for significant future reserve additions in North and South America and in the Tenke Fungurume minerals district. The drilling data in North America continue to indicate the potential for significantly expanded sulfide production.

Exploration spending associated with mining operations is expected to approximate $120 million for the year 2014, compared to $182 million in 2013.

Preliminary Recoverable Proven and Probable Mineral Reserves.FCX has significant reserves, resources and future development opportunities within its portfolio of mining assets. FCX's preliminary estimated consolidated recoverable proven and probable reserves from its mines at December 31, 2013, include 111.2 billion pounds of copper, 31.3 million ounces of gold and 3.26 billion pounds of molybdenum, which were determined using long-term average prices of $2.00 per pound for copper (consistent with the long-term average copper price used since December 31, 2010), $1,000 per ounce for gold and $10.00 per pound for molybdenum. The preliminary recoverable proven and probable mining reserves presented in the table below represent the estimated metal quantities from which FCX expects to be paid after application of estimated metallurgical recovery rates and smelter recovery rates, where applicable. Recoverable reserve volumes are those which FCX estimates can be economically and legally extracted or produced at the time of the reserve determination.

At December 31, 2013, in addition to preliminary consolidated recoverable proven and probable reserves, FCX's preliminary estimated mineralized material (assessed using a long-term average copper price of $2.20 per pound for copper) totals 115 billion pounds of incremental contained copper. FCX continues to pursue opportunities to convert this mineralized material into reserves, future production volumes and cash flow.

OIL & GAS OPERATIONS

During second-quarter 2013, FCX consummated acquisitions of Plains Exploration & Production Company (PXP) and McMoRan Exploration Co. (MMR), collectively FM O&G, adding an attractive oil and gas portfolio to its global mining business. FCX's oil and gas operations provide exposure to energy markets with positive fundamentals, strong margins and cash flows and a large resource base with financially attractive exploration and development investment opportunities. The portfolio of assets includes significant oil production facilities and growth potential in the Deepwater Gulf of Mexico (GOM), strong oil production from the onshore Eagle Ford shale play in Texas, established oil production facilities onshore and offshore California, large onshore resources in the Haynesville shale play in Louisiana, and an industry leading position in the emerging shallow water, Inboard Lower Tertiary/Cretaceous gas trend on the Shelf of the GOM and onshore in South Louisiana (previously referred to as the Ultra-deep trend). More than 90 percent of FCX's oil and gas revenues are from oil and NGLs.

For the seven month period following the acquisition date, FM O&G generated operating cash flows of $1.8 billion, which exceeded its capital expenditures of $1.45 billion.

FM O&G follows the full cost method of accounting whereby all costs associated with oil and gas acquisition, exploration and development activities are capitalized. Capitalized costs, along with estimated future costs to develop proved reserves, are amortized to expense under the unit-of-production method using estimates of proved oil and natural gas reserves. The costs of unproved oil and gas properties are excluded from depletion until the properties are evaluated, at which time the related costs are subject to depletion. Under the full cost accounting

Freeport-McMoRan Copper & Gold11

rules, a "ceiling test" is conducted each quarter to review the carrying value of the oil and gas properties for impairment.

California	39	39
Haynesville/Madden/Other	21	21
Total oil and gas operations	181	178

a. Includes sales from properties on the GOM Shelf and in the Deepwater GOM. Production from the GOM Shelf totaled 12 MBOE per day (17 percent of the GOM total) for fourth-quarter2013 and 13 MBOE per day (18 percent of the GOM total) for the seven-month period from June 1, 2013, to December 31, 2013.

Fourth-quarter2013 daily sales volumes averaged 181 MBOE, including 127 MBbls of crude oil per day, 249 MMcf of natural gas per day and 11 MBbls of NGLs per day. Fourth-quarter2013 production volumes were higher than the October 2013 estimate of 175 MBOE per day reflecting higher Eagle Ford production, continued strong performance in the GOM and stable production from California.

Sales volumes from oil and gas operations are expected to average 170 MBOE per day for first-quarter 2014 and 166 MBOE per day for the year 2014, comprised of approximately 70 percent oil, 24 percent natural gas and 6 percent NGLs. Sales volumes for the year 2014 include the impacts of planned platform maintenance and subsea tie-back upgrades on the Marlin facility in the GOM during third-quarter 2014.

Cash production costs were $17.63 per BOE in fourth-quarter2013 and $17.14 per BOE for the seven month period following the acquisition date. Based on current sales volume and cost estimates, cash production costs are expected to approximate $20 per BOE for the year 2014, primarily reflecting the impact of lower estimated volumes.

Exploration, Operating and Development Activities.FCX's oil and gas business has significant proved, probable and possible reserves, with financially attractive organic growth opportunities. The portfolio includes a broad range of relatively low-risk development opportunities and high-potential exploration prospects. The business is being managed to reinvest its cash flows in projects with attractive rates of returns and risk profiles.

Capital expenditures for oil and gas operations approximated $523 million for fourth-quarter2013, including $204 million incurred for Eagle Ford, $136 million for the GOM (principally Deepwater), $61 million for California and $93 million for the Inboard Lower Tertiary/Cretaceous gas trend. Capital expenditures for oil and gas operations, which are expected to be funded by its operating cash flows, are projected to approximate $3 billion for the year 2014, including $1.5 billion incurred for the Deepwater GOM, $0.4 billion for Eagle Ford and $0.3 billion for the Inboard Lower Tertiary/Cretaceous gas trend.

Gulf of Mexico. Multiple development and exploration opportunities have been identified in the Deepwater GOM that are expected to benefit from tie-back opportunities to available production capacity at the FM O&G operated large-scale Holstein, Marlin and Horn Mountain deepwater production platforms.

Holstein, in which FM O&G has a 100 percent working interest, is located in Green Canyon and has production facilities capable of producing in excess of 100 MBOE per day. The Holstein rig refurbishment program was conducted in the second half of 2013 in preparation for drilling activity, which commenced in first-quarter 2014. Over the 2014 to 2016 period, FM O&G expects to drill seven sidetrack wells from the Holstein platform and five subsea tie-back wells from contracted drill ships to enhance production volumes from the spar. Near-term tie-back prospects in the Holstein area include Holstein Deep and Copper.

The Holstein Deep development, in which FM O&G has a 100 percent working interest, is located four miles west of the Holstein platform. FM O&G acquired the acreage associated with this development in the 2013 lease sale. Two successful wells had previously been drilled and encountered approximately 500 net feet of oil pay in recent years. FM O&G plans to delineate this prospect during 2014.

Freeport-McMoRan Copper & Gold13

The Copper exploration prospect, in which FM O&G has a 100 percent working interest, is located southeast of the Holstein field in 4,400 feet of water and is a subsea tie-back opportunity to the Holstein facility. The prospect is a Holstein analog play with Pliocene objectives and has a proposed total depth of 14,500 feet.

Development of the Lucius field in Keathley Canyon, in which FM O&G has a 23.33 percent working interest, is progressing with first production anticipated in the second half of 2014. The geologic results from the six wells drilled since 2009 confirm a significant oil resource. Subsea infrastructure is currently being installed, and topside facilities are more than 90 percent complete and on schedule to be delivered and lifted into place during first-quarter 2014. The sanctioned development of Lucius is a subsea development consisting of a truss spar hull located in 7,200 feet of water with a topside capacity of 80 MBbls of oil per day and 450 MMcf of gas per day.

During 2014, FM O&G also plans to commence drilling at the Tara exploration prospect, in which FM O&G has a 100 percent working interest, located northwest of the Lucius discovery in Keathley Canyon in 8,700 feet of water. Tara is a Lucius analog prospect with Pliocene/Miocene objectives and has a proposed total depth of 23,000 feet.

Eagle Ford. FM O&G has an attractive position in an oil and NGLs rich section of the Eagle Ford shale play in South Texas. Production from the field has grown significantly in recent years and sales averaged 48 MBOE per day in fourth-quarter2013. As part of its capital reduction initiatives, FM O&G has reduced drilling activity at Eagle Ford from eight rigs in mid-2013. At December 31, 2013, there were three drilling rigs operating, which FM O&G expects to reduce to two during 2014. At December 31, 2013, 32 wells have been drilled and are waiting on completion or connection to pipelines.

California.Development plans are principally focused on maintaining stable production levels in the long established producing fields onshore California. Sales averaged 39 MBOE per day in fourth-quarter2013, with 96 percent from oil.

Haynesville. FM O&G has rights to a substantial natural gas resource, located in the Haynesville shale play in north Louisiana. Drilling activities in recent years have been significantly reduced to maximize cash flows in a low natural gas price environment and to benefit from potentially higher future natural gas prices.

Inboard Lower Tertiary/Cretaceous (previously referred to as the Ultra-deep). FM O&G has an industry leading position in the emerging Inboard Lower Tertiary/Cretaceous gas trend, located in the shallow waters of the GOM and onshore South Louisiana. FM O&G has a significant onshore and offshore lease acreage position with high-quality prospects and the potential to develop a significant long-term, low-cost source of natural gas. Data from eight wells drilled to date indicate the presence of geologic formations that are analogous to productive formations in the Deepwater GOM and onshore in the Gulf Coast region. The near-term focus is on defining the trend onshore. FM O&G currently is drilling one onshore Inboard Lower Tertiary/Cretaceous exploration prospect and plans to complete and perform production tests on three wells in 2014, including one onshore well.

The Lomond North exploratory well in the Highlander area, in which FM O&G is the operator and has a 72 percent working interest, located in St. Martin Parish, Louisiana, is currently drilling and has encountered gas pay in several Wilcox and Cretaceous aged sands between 24,000 feet and 29,000 feet. The wireline log and core data obtained from the Wilcox and Cretaceous sand packages evaluated to date indicate favorable reservoir characteristics with approximately 150 feet of net pay. FM O&G will continue drilling the Lomond North well in the Cretaceous to test deeper prospective targets. FM O&G plans to commence completion operations in mid-2014 followed by a flow test. FM O&G has identified multiple exploratory prospects in the Highlander area where it controls rights to approximately 56,000 gross acres.

In fourth-quarter2013, FM O&G commenced completion operations at Davy Jones No. 2, in which FM O&G has a 75 percent working interest, located on South Marsh Island Block 234. Flow testing is anticipated in the first half of 2014. During 2014, FM O&G also plans to complete the Blackbeard West No.2 well, in which FM O&G has a 92 percent working interest, located on Ship Shoal Block 188. The Lineham Creek exploration well, in which FM O&G has a 36 percent working interest, located in Cameron Parish has been suspended while future plans are being developed.

CASH FLOWS, CASH and DEBT

Operating Cash Flows. FCX generated operating cash flows of $2.3 billion in fourth-quarter2013 (including $53 million of net working capital sources and changes in other tax payments) and $6.1 billion for the year 2013 (net of $436 million of working capital uses and changes in other tax payments).

Based on current sales volume and cost estimates and assuming average prices of $3.25 per pound of copper, $1,200 per ounce of gold, $9.50 per pound of molybdenum, and $105 per barrel of Brent crude oil, FCX's consolidated operating cash flows are estimated to approximate $9 billion for the year 2014 (including $0.8 billion of working capital sources and changes in other tax payments). The impact of price changes on operating cash flows would approximate $370 million for each $0.10 per pound change in the average price of copper, $85 million for each $50 per ounce change in the average price of gold, $120 million for each $2 per pound change in the average price of molybdenum and $125 million for each $5 per barrel change in the price of Brent crude oil above $100 per barrel.

Capital Expenditures. Capital expenditures totaled $1.7 billion for fourth-quarter2013 and $5.3 billion for the year 2013, including capital expenditures for oil and gas operations totaling $523 million for the fourth-quarter and $1.45 billion for the seven-month period from June 1, 2013, to December 31, 2013.

Capital expenditures are currently expected to approximate $7 billion for the year 2014, including $3 billion for major projects at mining operations and $3 billion for oil and gas operations. Major projects at mining operations for the year 2014 primarily include the expansions at Cerro Verde and Morenci and underground development activities at Grasberg.

During 2013, FCX took steps to reduce or defer capital expenditures in response to market conditions and debt reduction objectives. Capital spending plans remain under review and will be revised as market conditions warrant.

Cash. Following is a summary of cash available to the parent company, net of noncontrolling interests' share, taxes and other costs at December 31, 2013 (in billions):

Cash at domestic companies	$	0.4
Cash at international operations	1.6
Total consolidated cash and cash equivalents	2.0
Less: Noncontrolling interests' share	(0.6		)
Cash, net of noncontrolling interests' share	1.4

Debt. Following is a summary of total debt and related weighted-average interest rates at December 31, 2013 (in billions, except percentages):

				Weighted-
				Average
				Interest Rate
Acquisition-related debt	$	10.5	a	3.0%
Assumed debt of PXP	6.7			6.8%
FCX's previously existing debt	3.5			3.4%
	$	20.7		4.2%

a. FCX used the proceeds from the issuance of $6.5 billion of senior notes and a $4.0 billion bank term loan to finance the acquisitions of PXP and MMR and repay certain PXP debt.

FCX is targeting reductions in total debt to $12 billion by year-end 2016. FCX will continue to review its portfolio of assets and will consider opportunities to accelerate its deleveraging plans through potential asset sales, joint venture transactions or further adjustments to capital spending plans.

At December 31, 2013, FCX had no borrowings outstanding and $46 million of letters of credit issued under its $3.0 billion revolving credit facility.

FINANCIAL POLICY

FCX has a long-standing tradition of seeking to build shareholder value through investing in projects with attractive rates of return and returning cash to shareholders through common stock dividends and share purchases. FCX paid common stock dividends of $2.3 billion during 2013, which included $1.0 billion for a supplemental dividend of $1.00 per share paid on July 1, 2013.

FCX's current annual dividend rate for its common stock is $1.25 per share. On December 20, 2013, FCX's Board of Directors (the Board) declared a regular quarterly dividend of $0.3125 per share, which will be paid on February 3, 2014. The declaration of dividends is at the discretion of the Board and will depend upon FCX's financial results, cash requirements, future prospects and other factors deemed relevant by the Board.

FCX intends to continue to maintain a strong financial position, with a focus on reducing debt while continuing to invest in attractive growth projects and providing cash returns to shareholders. The Board will continue to review FCX's financial policy on an ongoing basis.

Cautionary Statement and Regulation G Disclosure: This press release contains forward-looking statements in which FCX discusses its potential future performance. Forward-looking statements are all statements other than statements of historical facts, such as projections or expectations relating to ore grades and milling rates, production and sales volumes, unit net cash costs, cash production costs per barrel of oil equivalent (BOE), operating cash flows, capital expenditures, exploration efforts and results, development and production activities and costs, liquidity, tax rates, the impact of copper, gold, molybdenum, cobalt, oil and gas price changes, the impact of derivative positions, the impact of deferred intercompany profits on earnings, reserve estimates, and future dividend payments, debt reduction and share purchases. The words “anticipates,” “may,” “can,” “plans,” “believes,” "potential," “estimates,” “expects,” “projects”, "targets," “intends,” “likely,” “will,” “should,” “to be,” and any similar expressions are intended to identify those assertions as forward-looking statements. The declaration of dividends is at the discretion of FCX's Board and will depend on FCX's financial results, cash requirements, future prospects, and other factors deemed relevant by the Board.

This press release also includes forward-looking statements regarding mineralized material not included in proven and probable mineral reserves. The mineralized material described in this press release will not qualify as reserves until comprehensive engineering studies establish their economic feasibility. Accordingly, no assurance can be given that the estimated mineralized material not included in reserves will become proven and probable reserves.

FCX cautions readers that forward-looking statements are not guarantees of future performance and its actual results may differ materially from those anticipated, projected or assumed in the forward-looking statements. Important factors that can cause FCX's actual results to differ materially from those anticipated in the forward-looking statements include commodity prices, mine sequencing, production rates, industry risks, regulatory changes, political risks, the outcome of ongoing discussions with the Indonesian government regarding PT-FI's Contract of Work and the impact of the January 2014 regulations on PT-FI's exports and export duties, the potential effects of violence in Indonesia, the resolution of administrative disputes in the Democratic Republic of Congo, weather- and climate-related risks, labor relations, environmental risks, litigation results, currency translation risks, and other factors described in more detail under the heading “Risk Factors” in FCX's Annual Report on Form 10-K for the year ended December 31, 2012, filed with the U.S. Securities and Exchange Commission (SEC) as updated by FCX's subsequent filings with the SEC.

Investors are cautioned that many of the assumptions on which FCX's forward-looking statements are based are likely to change after its forward-looking statements are made, including for example commodity prices, which FCX cannot control, and production volumes and costs, some aspects of which FCX may or may not be able to control. Further, FCX may make changes to its business plans that could or will affect its results. FCX cautions investors that it does not intend to update forward-looking statements more frequently than quarterly notwithstanding any changes in FCX's assumptions, changes in business plans, actual experience or other changes, and FCX undertakes no obligation to update any forward-looking statements.

This press release also contains certain financial measures such as unit net cash costs per pound of copper and per pound of molybdenum, oil and gas realized revenues, cash production costs and cash operating margin, which are not recognized under generally accepted accounting principles in the U.S. As required by SEC Regulation G, reconciliations of these measures to amounts reported in FCX's consolidated financial statements are in the supplemental schedules of this press release, which are also available on FCX's website, “www.fcx.com.”

b. Cash operating margin for FCX's oil and gas operations reflects realized revenues less cash production costs. Realized revenues exclude unrealized gains (losses) on derivative contracts and cash production costs exclude accretion and other costs. In addition, derivative instruments for FCX's oil and gas operations are managed on a consolidated basis; accordingly, the average realized price per BOE by region does not reflect adjustments for derivative contracts. For reconciliations of average realized price and cash production costs per BOE to revenues and production and delivery costs reported in FCX's consolidated financial statements, refer to the supplemental schedule, “Product Revenues and Production Costs,” beginning on page XIII, which is available on FCX's website, “www.fcx.com.”

c. The increase in the fourth-quarter 2013 depreciation, depletion and amortization per BOE primarily resulted from (i) additional Deepwater GOM future development costs and (ii) the transfer of unevaluated property costs (which include fair value increases from purchase accounting) into costs subject to depletion.

d. Consolidated capital expenditures for oil and gas operations reflect total spending and include net adjustments totaling $7 million in fourth-quarter2013 and $135 million for the seven-month period from June 1, 2013, to December 31, 2013, which are not specifically allocated to the regions; capital expenditures by region reflect amounts incurred for the respective periods.

e. Includes properties on the Shelf and in the Deepwater GOM.

a. Represents income (loss) by geographic location before income taxes and equity in affiliated companies' net earnings.

b. Primarily resulting from changes in income contributed by each U.S. operation and refinement of state income tax filing positions.

c. In accordance with applicable accounting rules, FCX adjusts its interim provision for income taxes equal to its estimated annualized tax rate.

d. Reflects net reductions in FCX's deferred tax liabilities and deferred tax asset valuation allowances resulting from the second-quarter 2013 oil and gas acquisitions.

e. In July 2012, Sociedad Minera Cerro Verde S.A.A (Cerro Verde) signed a new 15-year mining stability agreement with the Peruvian government, which became effective upon the expiration of the previous mining stability agreement on December 31, 2013. In connection with the new mining stability agreement, Cerro Verde's income tax rate increased from 30 percent to 32 percent. As a result of the change in the income tax rate, FCX recognized additional deferred tax expense of $29 million ($25 million net of noncontrolling interests) in 2012, which relates primarily to the assets recorded in connection with the 2007 acquisition of Freeport-McMoRan Corporation.

f. Reflects the reversal of a net deferred tax liability totaling $234 million ($123 million net of noncontrolling interest) related to reinvested profits at Cerro Verde that were not distributed prior to expiration of its stability agreement on December 31, 2013.

g. FCX's consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which it operates. Accordingly, variations in the relative proportions of jurisdictional income result in fluctuations to FCX's consolidated effective income tax rate. Assuming average prices of $3.25 per pound for copper, $1,200 per ounce for gold, $9.50 per pound for molybdenum and Brent crude oil of $105 per barrel and achievement of current sales volume and cost estimates, FCX estimates its annual consolidated effective tax rate for the year 2014 will approximate 35 percent.

DERIVATIVE INSTRUMENTS

Provisional Pricing. For the year 2013, 49 percent of FCX's mined copper was sold in concentrate, 28 percent as cathode and 23 percent as rod from North America operations. Under the long-established structure of sales agreements prevalent in the industry, copper contained in concentrates and cathodes is provisionally priced at the time of shipment. The provisional prices are finalized in a contractually specified future month (generally one to four months from the shipment date) primarily based on quoted monthly average spot copper prices on the London Metal Exchange (LME). Because a significant portion of FCX's copper concentrate and cathode sales in any quarterly period usually remain subject to final pricing, the quarter-end forward price is a major determinant of recorded revenues and the average recorded copper price for the period. LME spot copper prices averaged $3.24 per pound during fourth-quarter 2013, compared to FCX's average realized price of $3.31 per pound.

Following is a summary of the (unfavorable) favorable impacts of net adjustments to prior periods' provisionally priced copper sales for the fourth quarters and years ended2013 and 2012 (in millions, except per share amounts):

	Three Months Ended						Years Ended
	December 31,						December 31,
	2013			2012			2013			2012
Revenues	$	(21	)	$	(73	)	$	(26	)	$	101
Net income attributable to common stock	$	(9	)	$	(31	)	$	(12	)	$	43
Net income per share of common stock	$	(0.01	)	$	(0.03	)	$	(0.01	)	$	0.05

At December 31, 2013, FCX had provisionally priced copper sales at its copper mining operations, primarily South America and Indonesia, totaling 481 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $3.34 per pound, subject to final pricing over the next several months. FCX estimates that each $0.05 change in the price realized from the December 31, 2013, provisional price recorded would have an approximate $16 million effect on 2014 net income attributable to common stock. The LME spot copper price closed at $3.33 per pound on January 21, 2014.

Oil and Gas.FCX's oil and gas operations use various derivative instruments to manage commodity price risk for a substantial portion of its oil and gas production. In connection with the acquisition of PXP, FCX assumed derivative contracts for 2013, 2014 and 2015 that consist of crude oil options, and crude oil and natural gas swaps. These oil and gas derivative contracts do not qualify or are not designated as hedging instruments; accordingly, they are recorded at fair value with the mark-to-market gains and losses recorded in revenues each period.

Net charges to revenues for realized losses on oil and gas derivative contracts totaled $11 million in fourth-quarter2013 and $22 million for the seven-month period following the acquisition date. Additionally, following is a summary of net charges for unrealized losses on oil and gas derivative contracts in fourth-quarter2013 and the seven-month period from June 1, 2013, to December 31, 2013 (in millions, except per share amounts):

				Seven Months From
	Three Months Ended			June 1, 2013 to
	December 31, 2013			December 31, 2013
Revenues	$	(118	)	$	(312	)
Net income attributable to common stock	$	(73	)	$	(194	)
Net income per share of common stock	$	(0.07	)	$	(0.19	)

As of December 31, 2013, the fair value of the oil and gas derivative contracts totaled a $131 million asset. Offsetting the fair value is $444 million in deferred premiums and interest to be settled in future periods. At December 31, 2013, first-quarter 2014 premium settlements of oil and gas derivative contracts are expected to result in realized losses of approximately $60 million, compared with $18 million for fourth-quarter 2013.

Following presents the estimated (increase) decrease in the net oil and gas derivative liability of a 10 percent change in Brent crude oil and NYMEX forward prices on the fair values of outstanding oil and gas derivative contracts, compared with forward prices used to determine the December 31, 2013, fair values:

	10% Increase (in millions)			10% Decrease (in millions)
Crude oil puts	$	(72	)	$	146
Natural gas swaps	(14		)	14
	$	(86	)	$	160

DEFERRED PROFITS

FCX defers recognizing profits on sales from its mining operations to Atlantic Copper and on 25 percent of Indonesia mining's sales to PT Smelting (PT Freeport Indonesia's 25 percent-owned Indonesian smelting unit) until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net reductions to net income attributable to common stock totaling $46 million in fourth-quarter2013, $10 million in fourth-quarter2012, $17 million for the year 2013 and $80 million for the year 2012. FCX's net deferred profits on its inventories at Atlantic Copper and PT Smelting to be recognized in future periods' net income attributable to common stock totaled $127 million at December 31, 2013. Based on current estimates, FCX expects deferred profits attributable to intercompany sales to result in an increase to net income of approximately $35 million in first-quarter 2014. Quarterly variations in ore grades, the timing of intercompany shipments and changes in product prices will result in variability in FCX's net deferred profits and quarterly earnings.

BUSINESS SEGMENTS

Subsequent to the oil and gas acquisitions, FCX has organized its operations into six primary divisions – North America copper mines, South America mining, Indonesia mining, Africa mining, Molybdenum mines and United States (U.S.) Oil & Gas operations. Notwithstanding this structure, FCX internally reports information on a mine-by-mine basis for its mining operations. Therefore, FCX concluded that its operating segments include individual mines or operations relative to its mining operations. For oil and gas operations, FCX determines its operating segments on a country-by-country basis. Operating segments that meet certain thresholds are reportable segments, which are separately disclosed in the following table.

Intersegment Sales. Intersegment sales between FCX’s mining operations are based on similar arms-length transactions with third parties at the time of the sale. Intersegment sales may not be reflective of the actual prices ultimately realized because of a variety of factors, including additional processing, timing of sales to unaffiliated customers and transportation premiums.

Allocations. FCX allocates certain operating costs, expenses and capital expenditures to its operating divisions and individual segments. However, not all costs and expenses applicable to an operation are allocated. U.S. federal and state income taxes are recorded and managed at the corporate level, whereas foreign income taxes are recorded and managed at the applicable country. In addition, most mining exploration and research activities are managed at the corporate level, and those costs along with some selling, general and administrative costs are not allocated to the operating divisions or individual segments. Accordingly, the following segment information reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity.

PRODUCT REVENUES AND PRODUCTION COSTS

Mining Product Revenues and Unit Net Cash Costs. Unit net cash costs per pound of copper and molybdenum are measures intended to provide investors with information about the cash-generating capacity of FCX's mining operations expressed on a basis relating to the primary metal product for the respective operations. FCX uses this measure for the same purpose and for monitoring operating performance by its mining operations. This information differs from measures of performance determined in accordance with U.S. generally accepted accounting principles (GAAP) and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. This measure is presented by other metals mining companies, although FCX's measures may not be comparable to similarly titled measures reported by other companies.

FCX presents gross profit per pound of copper in the following tables using both a “by-product” method and a “co-product” method. FCX uses the by-product method in its presentation of gross profit per pound of copper because (i) the majority of its revenues are copper revenues, (ii) it mines ore, which contains copper, gold, molybdenum and other metals, (iii) it is not possible to specifically assign all of FCX's costs to revenues from the copper, gold, molybdenum and other metals it produces, (iv) it is the method used to compare mining operations in certain industry publications and (v) it is the method used by FCX's management and Board of Directors to monitor mining operations. In the co-product method presentations, shared costs are allocated to the different products based on their relative revenue values, which will vary to the extent FCX's metals sales volumes and realized prices change.

FCX shows revenue adjustments for prior period open sales as separate line items. Because these adjustments do not result from current period sales, these amounts have been reflected separately from revenues on current period sales. Noncash and other costs consist of items such as stock-based compensation costs, start-up costs, write-offs of equipment and/or unusual charges. They are removed from site production and delivery costs in the calculation of unit net cash costs. As discussed above, gold, molybdenum and other metal revenues at copper mines are reflected as credits against site production and delivery costs in the by-product method. The following schedules are presentations under both the by-product and co-product methods together with reconciliations to amounts reported in FCX's consolidated financial statements.

Oil & Gas Product Revenues and Cash Production Costs per Unit. Realized revenues and cash production costs per unit are measures intended to provide investors with information about the cash operating margin of FCX's oil and gas operations expressed on a basis relating to each product sold. FCX uses this measure for the same purpose and for monitoring operating performance by its oil and gas operations. This information differs from measures of performance determined in accordance with U.S. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. FCX's measures may not be comparable to similarly titled measures reported by other companies.

FCX shows revenue adjustments from derivative instruments as separate line items. Because these adjustments do not result from oil and gas sales, these gains and losses have been reflected separately from revenues on current period sales. Additionally, accretion and other costs are removed from production and delivery costs in the calculation of cash production costs per BOE. The following schedules include calculations of oil and gas product revenues and cash production costs together with a reconciliation to amounts reported in FCX's consolidated financial statements.
