Consolidated Sales Volumes    

First-quarter2014 consolidated copper sales of 871 million pounds were lower than first-quarter2013 sales of 954 million pounds and the January 2014 estimate of 1.0 billion pounds. First-quarter2014 consolidated gold sales of 187 thousand ounces were lower than first-quarter2013 sales of 214 thousand ounces and the January 2014 estimate of 325 thousand ounces. Lower copper and gold sales volumes primarily reflected lower volumes from PT-FI because of the post-January 12, 2014, restrictions on concentrate exports from Indonesia, which resulted in a deferral of approximately 125 million pounds of copper and 140 thousand ounces of gold in first-quarter2014.

First-quarter2014 consolidated molybdenum sales of 27 million pounds were higher than first-quarter2013 and the January 2014 estimate of 25 million pounds.

First-quarter2014 sales from oil and gas operations of 16.1 MMBOE, including 11.8 million barrels (MMBbls) of crude oil, 19.5 billion cubic feet (Bcf) of natural gas and 1.1 MMBbls of natural gas liquids (NGLs), were higher than the January 2014 estimate of 15.3 MMBOE primarily reflecting higher Eagle Ford production volumes, continued strong performance in the Gulf of Mexico (GOM) and stable production from California.

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 could continue to export product through January 12, 2017, but established new requirements for the continued export of copper concentrates, including the imposition of a progressive export duty on copper concentrates. To date, PT-FI has not received authorization from the Indonesian government to export copper concentrate. The regulations and imposition of an export duty conflict with PT-FI's Contract of Work (COW). FCX is working with the Indonesian government to reach a resolution that would enable PT-FI to resume exports of concentrates.

As a result of the delay in obtaining approvals for 2014 exports, PT-FI implemented changes to its operations to align its concentrate production with PT Smelting's operating plans. During first-quarter 2014, PT-FI’s milling rate averaged 118,000 metric tons of ore per day, which is approximately half of normal rates. In the event that PT-FI is unable to conduct normal operations for an extended period, PT-FI intends to implement plans to reduce operating costs, defer capital expenditures and implement workforce reductions.

Consolidated sales for the year 2014 are expected to approximate 4.3 billion pounds of copper, 1.6 million ounces of gold, 97 million pounds of molybdenum and 64.2 MMBOE, including 1.1 billion pounds of copper, 320 thousand ounces of gold, 24 million pounds of molybdenum and 15.2 MMBOE for second-quarter2014. These estimates assume resumption of exports from PT-FI beginning in May 2014. To the extent PT-FI is unable to resume exports in May 2014, this would result in a deferral of approximately 50 million pounds of copper and 80 thousand ounces of gold per month.

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 $1.54 per pound of copper in first-quarter2014 were lower than unit net cash costs of $1.57 per pound in first-quarter2013. First-quarter2014 consolidated average unit net cash costs exclude $0.06 per pound of copper for fixed costs charged directly to cost of sales as a result of the impact of export restrictions on PT-FI's operating rates.

Assuming average prices of $1,300 per ounce of gold and $10 per pound of molybdenum for the remainder of2014 and achievement of current sales volume and cost estimates, which assumes the resumption of exports from PT-FI beginning in May 2014, consolidated unit net cash costs (net of by-product credits) for copper mines are expected to average $1.58 per pound of copper in second-quarter 2014 and $1.41 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). The impact of price changes for the remainder of2014 on consolidated unit net cash costs would approximate $0.017 per pound for each $50 per ounce change in the average price of gold and $0.015 per pound for each $2 per pound change in the average price of molybdenum.

Oil and Gas Cash Production Costs per BOE. Cash production costs for oil and gas operations were $18.51 per BOE in first-quarter2014. Based on current sales volume and cost estimates for the remainder of2014, cash production costs per BOE are expected to approximate $19 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, molybdenum concentrates are also produced by certain of FCX's North America copper mines.

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 to approximately 115,000 metric tons of ore per day. Construction is in an advanced stage, and FCX expects to begin commissioning and start-up activities during second-quarter 2014. At full rates, Morenci's copper production is expected to approach 1 billion pounds in 2015, compared with 564 million pounds in 2013. At March 31, 2014, $1.3 billion had been incurred for this project, with approximately $0.3 billion remaining to be incurred.

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 XI, which is available on FCX's website, "www.fcx.com."

North America's consolidated copper sales volumes of 371 million pounds in first-quarter2014 were higher than first-quarter2013 sales of 353 million pounds, reflecting higher production at most mines primarily because of higher ore grades. North America's copper production is expected to continue to grow in 2014 following the completion of the Morenci mill expansion project. Copper sales from the North America copper mines are expected to approximate 1.7 billion pounds for the year 2014, compared with 1.4 billion pounds in 2013.

Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.79 per pound of copper in first-quarter2014 were lower than unit net cash costs of $1.86 per pound in first-quarter2013, primarily reflecting higher copper sales volumes. Average unit net cash costs (net of by-product credits) for the North America copper mines are expected to approximate $1.75 per pound of copper for the year 2014, based on current sales volume and cost estimates and assuming an average molybdenum price of $10 per pound for the

Freeport-McMoRan             5

remainder of2014. North America's average unit net cash costs for the remainder of2014 would change by approximately $0.03 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 substantially complete and construction 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 March 31, 2014, $1.9 billion had been incurred for this project, with approximately $2.7 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.

South America's consolidated copper sales volumes of 307 million pounds in first-quarter2014 were higher than first-quarter2013 sales of 285 million pounds, primarily reflecting higher mining rates and timing of shipments. Sales from South America mining are expected to approximate 1.2 billion pounds of copper for the year 2014, which are lower than 2013 volumes of 1.3 billion pounds, primarily reflecting lower ore grades at Candelaria and Cerro Verde.

Freeport-McMoRan             6

Average unit net cash costs (net of by-product credits) for South America mining of $1.42 per pound of copper in first-quarter2014 were lower than unit net cash costs of $1.51 per pound in first-quarter2013, primarily reflecting higher copper sales volumes. Average unit net cash costs (net of by-product credits) for South America mining are expected to approximate $1.55 per pound of copper for the year 2014, based on current sales volume and cost estimates and assuming average prices of $1,300 per ounce of gold and $10 per pound of molybdenum for the remainder of2014.

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.PT-FI 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 process 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) underground 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). PT-FI may reduce or defer these activities pending resolution of export restrictions and other Indonesia regulatory matters.

Regulatory Matters. In January 2014, the Indonesian government published regulations providing that holders of contracts of work with existing processing facilities in Indonesia could continue to export product through January 12, 2017, but established new requirements for the continued export of copper concentrates, including the imposition of a 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 specifies the taxes and other fiscal terms available 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. Additionally, PT-FI complied with the requirements of its COW for local processing by arranging for the construction and commissioning of Indonesia's only copper smelter and refinery, which is owned by PT Smelting. Prior to the January 12, 2014,regulations on exporting copper concentrates, approximately 40 percent of PT-FI’s production during 2014 had been 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.

To date, PT-FI has not received authorization from the Indonesian government to export copper concentrate. The January 12, 2014, regulations and the imposition of an export duty conflict with PT-FI’s contractual rights under its COW. FCX is working with the Indonesian government to reach a resolution that would enable PT-FI to resume exports of copper concentrates.

As a result of the delay in obtaining approvals for 2014 exports, PT-FI has implemented changes to its operations to align its concentrate production with PT Smelting’s operating plans. During first-quarter 2014, PT-FI’s milling rate averaged 118,000 metric tons of ore per day, which is approximately half of normal rates. In the event that PT-FI is unable to conduct normal operations for an extended period, PT-FI intends to implement plans to reduce operating costs, defer capital expenditures and implement workforce reductions.

a. First-quarter2014 site production and delivery and unit net cash costs exclude $0.49 per pound of copper for fixed costs charged directly to cost of sales as a result of the impact of export restrictions on PT-FI's operating rates. 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 XI, which is available on FCX's website, "www.fcx.com."

Indonesia's first-quarter2014 sales of 109 million pounds of copper and 162 thousand ounces of gold were lower than first-quarter2013 sales of 198 million pounds of copper and 191 thousand ounces of gold, primarily because of lower milling rates as a result of the restrictions on concentrate exports from Indonesia, which resulted in the deferral of approximately 125 million pounds of copper and 140 thousand ounces of gold in first-quarter2014.

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 0.9 billion pounds of copper and 1.5 million ounces of gold for the year 2014, compared with 0.9 billion pounds of copper and 1.1 million ounces of gold for the year 2013. These estimates assume resumption of exports from PT-FI beginning in May 2014. To the extent PT-FI is unable to resume exports in May 2014, this will result in a deferral of approximately 50 million pounds of copper and 80 thousand ounces of gold per month. Upon a favorable resolution of the restrictions on exports matter, sales from Indonesia mining are expected to increase through 2016 as PT-FI gains access to higher grade ore.

A significant portion of PT-FI's costs are fixed and unit costs vary depending on production volumes. During first-quarter2014, PT-FI operated at approximately half of normal rates. Indonesia's unit net cash costs exclude $0.49 per pound of copper for fixed costs charged directly to cost of sales as a result of the impact of export restrictions on PT-FI's operating rates. Excluding this amount, Indonesia's unit net cash costs (including gold and silver credits) of $1.53 per pound of copper in first-quarter2014 were higher than unit net cash costs of $1.34 per pound in first-quarter2013, primarily reflecting lower volumes.

Unit net cash costs (net of gold and silver credits) for Indonesia mining are expected to approximate $0.70 per pound of copper for the year 2014, based on current sales volume and cost estimates, which assumes the resumption of exports from PT-FI beginning in May 2014, and assuming an average gold price of $1,300 per ounce for the remainder of2014. 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 for the remainder of2014. 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 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 increasing mine, mill and processing capacity. The expanded mill's throughput rates averaged 14,500 metric tons per day for first-quarter2014, compared with the project's design capacity of 14,000 metric tons of ore per day. 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 84 million pounds in first-quarter2014 were lower than first-quarter2013 copper sales of 118 million pounds, primarily reflecting timing of shipments and lower grade ore. TFM's sales are expected to approximate 440 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.

Africa mining's unit net cash costs (net of cobalt credits) of $0.89 per pound of copper in first-quarter2014 were lower than unit net cash costs of $1.23 per pound of copper in first-quarter2013, primarily reflecting higher cobalt credits, partly offset by lower copper sales volumes. Unit net cash costs (net of cobalt credits) for Africa mining are expected to approximate $1.22 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 pound for the remainder of2014. Africa mining's projected unit net cash costs would change by approximately $0.065 per pound for each $2 per pound change in the average price of cobalt for the remainder of2014.

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. The majority of molybdenum concentrates produced at the Henderson and Climax mines, as well as from North and South America copper mines, are processed at FCX's conversion facility.

Operating Data. Following is summary consolidated operating data for the molybdenum mines for the first quarters of 2014 and 2013:

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 XI, 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. While prices have improved somewhat during 2014, FCX continues to monitor market conditions and may make adjustments to its primary molybdenum production as market conditions warrant.

Average unit net cash costs for the Molybdenum mines of $6.71 per pound of molybdenum in first-quarter2014 were lower than average unit net cash costs of $7.32 per pound in first-quarter2013, primarily reflecting lower input costs and treatment charges. 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 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.

OIL & GAS OPERATIONS

In second-quarter 2013, FCX acquired oil and gas operations by completing the acquisitions of Plains Exploration & Production Company (PXP) and McMoRan Exploration Co. (MMR), collectively FM O&G. 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 GOM, strong oil production from the onshore Eagle Ford shale play in Texas, established oil production facilities onshore and offshore California, large onshore natural gas resources in the Haynesville shale play in Louisiana, natural gas production from the Madden area in central Wyoming, and an industry-leading position in the emerging shallow-water Inboard Lower Tertiary/Cretaceous natural gas trend on the Shelf of the GOM and onshore in South Louisiana. More than 90 percent of FCX's oil and gas revenues are from oil and NGLs.

FM O&G follows the full cost method of accounting whereby all costs associated with oil and gas property acquisition, exploration and development activities are capitalized into cost centers on a country-by-country basis. 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 amortization until the properties are evaluated, at which time the related costs are subject to amortization. Under the full cost accounting rules, a "ceiling test" is conducted each quarter to review the carrying value of the oil and gas properties for impairment.

a. Cash operating margin for oil and gas operations reflects realized revenues less cash production costs. Realized revenues exclude noncash mark-to-market adjustments on derivative contracts and cash production costs exclude accretion and other costs. For reconciliations of realized revenues and cash production costs 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 XI, which is available on FCX's website, “www.fcx.com.”

FM O&G's realized revenues totaled $1.2 billion ($77.22 per BOE) and cash production costs totaled $298 million ($18.51 per BOE) in first-quarter2014. Based on current sales volume and cost estimates for the remainder of2014, cash production costs are expected to approximate $19 per BOE for the year 2014, which is lower than the January 2014 estimate primarily reflecting the impact of higher estimated volumes.

In first-quarter2014, FM O&G's average realized price for crude oil was $93.76 per barrel (net of $4.86 per barrel associated with payments on derivative contracts). Excluding the impact of derivative contracts, FM O&G's average realized price for crude oil was $98.62 per barrel in first-quarter2014 (91 percent of the average Brent crude oil price of $107.84 per barrel).

FM O&G's average realized price for natural gas was $4.67 per MMBtu in first-quarter2014. Excluding the impact of derivative contracts, the average realized price for natural gas was $5.05 per MMBtu in first-quarter2014, compared to the New York Mercantile Exchange (NYMEX) natural gas price average of $4.92 per MMBtu for the January through March 2014 contracts.

Following is a summary of average sales volumes per day by region for oil and gas operations for first-quarter2014 :

	Three Months Ended
	March 31, 2014
Sales Volumes (MBOE per day):
GOMa	70
Eagle Ford	53
California	39
Haynesville/Madden/Other	17
Total oil and gas operations	179

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).

Daily sales volumes averaged 179 MBOE for first-quarter2014, including 131 MBbls of crude oil, 216 MMcf of natural gas and 12 MBbls of NGLs. First-quarter2014 volumes were higher than the January 2014 estimate of 170 MBOE per day, reflecting higher Eagle Ford production, continued strong performance in the GOM and stable production from California. Oil and gas sales volumes are expected to average 176 MBOE per day for the year 2014, comprised of 71 percent oil, 23 percent natural gas and 6 percent NGLs. Annual estimates are approximately 10 MBOE per day higher than the January 2014 estimates primarily related to a deferral of the planned shut-in at Marlin from 2014 to 2015.

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 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 $581 million for first-quarter2014, including $277 million incurred for GOM (principally Deepwater), $127 million for Eagle Ford, $126 million for the Inboard Lower Tertiary/Cretaceous natural gas trend and $53 million for California. 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 natural 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.

In March 2014, FM O&G was the apparent high bidder on 20 tracts in the Central Gulf of Mexico Oil and Gas Lease Sale 231 with a total investment of approximately $330 million net to FM O&G. The winning bids were primarily focused on high-impact, drillable targets in the Mississippi Canyon, Atwater Valley and Green Canyon areas to complement FM O&G’s existing infrastructure and production facilities and add several new exploration plays. The blocks, which cover approximately 106,000 gross acres, range in water depths up to 6,000 feet. The bids are subject to approval by the U.S. Bureau of Ocean Energy Management (BOEM), and FM O&G expects to be notified and designated as the operator of these blocks by third-quarter 2014.

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. Drilling from the Holstein platform rig commenced in first-quarter 2014. Over the 2014 to 2016 period, FM O&G expects to drill seven sidetrack wells from the Holstein platform. In April 2014, the first sidetrack well was successful and completion operations have commenced. During this period, FM O&G also plans to drill five subsea tie-back wells from contracted drillships 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

Freeport-McMoRan             12

sale held by the BOEM. 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.

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 on track with first oil 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 were 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 daily capacity of 80 MBbls of oil and 450 MMcf of gas.

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 a section rich in crude oil and NGLs of the Eagle Ford shale play in South Texas. Production from the field has grown significantly in recent years and sales averaged 53 MBOE per day in first-quarter2014. As part of capital reduction initiatives, FM O&G has reduced drilling activity at Eagle Ford from eight operated rigs in mid-2013 to two operated rigs at the end of first-quarter2014. At March 31, 2014, there were 23 wells that were pending completion or connection to pipelines.

California. FM O&G's California assets continued to perform consistently, with first-quarter2014 production averaging 39 MBOE per day. Development plans are principally focused on maintaining stable production levels in the long- established producing fields onshore California through continued drilling.

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. FM O&G has an industry-leading position in the emerging Inboard Lower Tertiary/Cretaceous natural gas trend, located on the Shelf 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 is currently completing two Inboard Lower Tertiary/Cretaceous exploration prospects, including one onshore well, and plans to perform production tests on these two wells and a third well in 2014.

The Highlander onshore exploratory well, in which FM O&G is the operator and has a 72 percent working interest, located in St. Martin Parish, Louisiana, encountered gas pay in several Wilcox and Cretaceous sands between 24,000 feet and 29,000 feet. As reported in January 2014, the wireline log and core data obtained from the Wilcox and Cretaceous sand packages indicated favorable reservoir characteristics with approximately 150 feet of net pay. The Highlander discovery well is currently in completion operations to test Lower Wilcox and Cretaceous objectives found below the salt weld. Flow testing is anticipated in the second half of 2014. FM O&G has identified multiple exploratory prospects in the Highlander area where it controls rights to approximately 56,000 gross acres.

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, are in progress. Flow testing is anticipated to begin during second-quarter 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. Other near-term drilling includes the Farthest Gate West exploratory prospect located onshore in Cameron Parish, Louisiana. Farthest Gate West is a Lineham Creek analog prospect with Paleogene objectives and has a proposed total depth of 25,000 feet.

CASH FLOWS, CASH and DEBT

Operating Cash Flows. FCX generated operating cash flows of $1.2 billion (net of $377 million in working capital uses and changes in other tax payments) for first-quarter2014.

Based on current sales volume and cost estimates and assuming average prices of $3.00 per pound of copper, $1,300 per ounce of gold, $10 per pound of molybdenum and $105 per barrel of Brent crude oil for the remainder of2014, FCX's consolidated operating cash flows are estimated to approximate $7.7 billion (including $0.1 billion of working capital sources and changes in other tax payments) for the year 2014. The impact of price changes for the remainder of2014 on operating cash flows would approximate $275 million for each $0.10 per pound change in the average price of copper, $60 million for each $50 per ounce change in the average price of gold, $85 million for each $2 per pound change in the average price of molybdenum and $100 million for each $5 per barrel change in the average price of Brent crude oil above $100 per barrel.

Capital Expenditures. Capital expenditures totaled $1.6 billion for first-quarter2014, including $0.7 billion for major projects at mining operations and $0.6 billion for oil and gas operations.

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.

Cash. Following is a summary of cash available to the parent company, net of noncontrolling interests' share, taxes and other costs at March 31, 2014 (in millions):

Less: noncontrolling interests' share	(494		)
Cash, net of noncontrolling interests' share	884
Less: withholding taxes and other	(76		)
Net cash available	$	808

Debt. FCX continues to target significant reductions in debt by the end of 2016 using cash flows generated above capital expenditures and other cash requirements. FCX will seek opportunities to accelerate its deleveraging plans through potential asset sales, joint venture transactions or other monetizations and is engaged in discussions with a number of third parties to achieve this objective. FCX may also take additional steps to reduce or defer capital spending and other costs in response to market conditions. Following is a summary of total debt and related weighted-average interest rates at March 31, 2014 (in billions, except percentages):

			Weighted-
			Average
			Interest Rate
Acquisition-related debt	$	10.5	3.0%
Assumed debt of PXP	6.7		6.8%
Other FCX debt	3.7		3.3%
	$	20.9	4.2%

At March 31, 2014, FCX had no borrowings outstanding and $46 million of letters of credit issued under its revolving credit facility, resulting in availability of approximately $3.0 billion.

In March 2014, FCX entered into a five-year, $1.8 billion senior unsecured term loan to fund a portion of the Cerro Verde expansion project. Amounts are expected to be drawn over time as required to fund the project. No amounts were drawn at March 31, 2014.

FCX has announced that FM O&G will redeem on April 30, 2014, a total of $210 million of the aggregate principal amount of the outstanding 6.625% Senior Notes. Holders will receive the principal amount together with the redemption premium and accrued and unpaid interest to the redemption date.

a. Cash operating margin for oil and gas operations reflects realized revenues less cash production costs. Realized revenues exclude noncash mark-to-market adjustments on derivative contracts, and cash production costs exclude accretion and other costs. In addition, the derivative contracts for 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 XI, which is available on FCX's website, “www.fcx.com.”

b. Consolidated capital expenditures for oil and gas operations reflect total spending, which is net of accrual and other adjustments totaling $(29) million that are not specifically allocated to the regions.

c. Reflects properties in the Deepwater GOM and on the Shelf, including the Inboard Lower Tertiary/Cretaceous natural gas trend.

PROVISION FOR INCOME TAXES

Following are summaries of the approximate amounts in the calculation of FCX's consolidated provision for income taxes for the first quarters of 2014 and 2013 (in millions, except percentages):

	Three Months Ended March 31,
	2014							2013

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

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

c. 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 achievement of current sales volume and cost estimates and average prices of $3.00 per pound for copper, $1,300 per ounce for gold, $10 per pound for molybdenum and $105 per barrel of Brent crude oil for the remainder of 2014, FCX estimates its consolidated effective tax rate will approximate 36 percent for the year 2014. In January 2014, the Indonesian government published regulations regarding exports of minerals, including copper concentrates. FCX is working with the Indonesian government to reach a resolution that would enable PT-FI to resume exports of concentrates as soon as possible. A reduction in income from PT-FI relative to FCX’s consolidated income during 2014 would generate a lower consolidated effective tax rate for the year.

DERIVATIVE INSTRUMENTS

Provisional Pricing. For first-quarter2014, 43 percent of FCX's mined copper was sold in concentrate, 30 percent as cathode and 27 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 $3.19 per pound during first-quarter2014, compared to FCX's average realized price of $3.14 per pound. Following is a summary of the unfavorable impacts of net adjustments to prior periods' provisionally priced copper sales for the first quarters of 2014 and 2013 (in millions, except per share amounts):

	Three Months Ended
	March 31,
	2014			2013

Net income attributable to common stock	$	(66	)	$	(5	)
Net income per share of common stock	$	(0.06	)	$	(0.01	)

At March 31, 2014, FCX had provisionally priced copper sales at its copper mining operations, primarily South America and Indonesia, totaling 332 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $3.01 per pound, subject to final pricing over the next several months. FCX estimates that each $0.05 change in the price realized from the March 31, 2014, provisional price recorded would

DERIVATIVE INSTRUMENTS (continued)

have an approximate $11 million impact on 2014 net income attributable to common stock. The LME spot copper price closed at $3.01 per pound on April 23, 2014.

Oil and Gas.FCX's oil and gas operations use various derivative instruments to manage exposure to commodity price risk for a substantial portion of its oil and gas production in 2014 and oil production in 2015. In connection with the acquisition of Plains Exploration & Production Company (PXP), FCX has derivative contracts for 2014 and 2015 that consist of crude oil options and natural gas swaps. These crude oil and natural gas derivative contracts 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 crude oil and natural gas derivative contracts totaled $50 million in first-quarter2014, reflecting charges of $65 million ($39 million to net income attributable to common stock or $0.04 per share) for payments on derivative contracts, partly offset by net noncash mark-to-market gains totaling $15 million ($9 million to net income attributable to common stock or $0.01 per share).

At March 31, 2014, the fair value of the crude oil and natural gas derivative contracts totaled an $89 million asset; offsetting the fair value is $387 million in deferred premiums and interest to be settled in future periods.

Following presents the estimated (increase) decrease in the net liability on FCX's balance sheet of a 10 percent change in Brent crude oil and New York Mercantile Exchange (NYMEX) forward natural gas prices on the fair values of outstanding crude oil and natural gas derivative contracts, compared with forward prices used to determine the fair values at March 31, 2014 (in millions):

	10% Increase			10% Decrease
Crude oil puts	$	(59	)	$	135
Natural gas swaps	(11		)	11
	$	(70	)	$	146

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 additions to net income attributable to common stock totaling $16 million in first-quarter2014 and $25 million in first-quarter2013. 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 $76 million at March 31, 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 second-quarter 2013 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 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 level. In addition, most mining exploration and research activities are managed on a consolidated basis, and those costs along with some selling, general and administrative costs are not allocated to the operating divisions or 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 a separate line item. 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. 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.
