• During second-quarter 2016, FCX completed previously announced asset sales for aggregate cash consideration of $1.3 billion, including the $1.0 billion sale of an additional 13 percent undivided interest in Morenci. In May 2016, FCX entered into a definitive agreement to sell its interest in TF Holdings Limited for $2.65 billion in cash and contingent consideration of up to $120 million. In accordance with accounting guidelines, the results of Tenke are reported as discontinued operations for all periods presented.
• During second-quarter 2016, FCX entered into agreements to terminate FM O&G's three drilling rig contracts for a total of $755 million and potential contingent consideration depending on future oil prices. The settlements result in aggregate savings of approximately $350 million, compared to the previously contracted commitments.
• Through July 25, 2016, FCX exchanged $369 million in senior notes for approximately 28 million shares of its common stock in a series of privately negotiated transactions, including $268 million exchanged during second-quarter 2016.
• At June 30, 2016, consolidated debt totaled $19.3 billion and consolidated cash totaled $352 million. At June 30, 2016, FCX had no borrowings and $3.5 billion available under its $3.5 billion revolving credit facility.

Freeport-McMoRan Inc. (NYSE: FCX) reported net losses attributable to common stock of $479 million, $0.38 per share, for second-quarter 2016 and $4.7 billion, $3.70 per share, for the first six months of 2016, compared with $1.85 billion, $1.78 per share, for second-quarter 2015 and $4.3 billion, $4.16 per share, for the first six months of 2015. FCX’s net losses attributable to common stock include net charges totaling $452 million, $0.36 per share, for second-quarter 2016 and $4.4 billion, $3.53 per share, for the first six months of 2016, primarily for impairment of oil and gas properties and drillship settlements/idle rig costs, partly offset by net gains on the sales of assets. Second-quarter 2015 included net charges of $2.0 billion, $1.92 per share, and the first six months of 2015 included net charges of $4.4 billion, $4.24 per share, primarily for the impairment of oil and gas properties. For further discussion of these net charges refer to the supplemental schedule "Adjusted Net (Loss) Income," on page IX, which is available on FCX's website, "fcx.com."

Richard C. Adkerson, President and Chief Executive Officer, said, "We are pleased to report significant progress toward our immediate objective of strengthening FCX’s balance sheet and enhancing shareholder value in a challenging market environment. Our global team continues to execute on our strategy to constrain costs and capital spending in a manner that protects the long-term values of our large resources. Our announced asset sale transactions totaling over $4 billion year-to-date demonstrate the attractiveness of our high-quality asset base. We are focused on executing our operating plans, which position us for significant free cash flow generation in the balance of 2016 and 2017, and on building long-term values from our portfolio of low-cost, long-lived reserves and resources for the benefit of our shareholders."

DEBT REDUCTION INITIATIVES

FCX previously announced plans to reduce debt and restore its balance sheet strength through a combination of asset sale transactions, cash flow from operations and potential capital market transactions. To date, FCX has announced over $4 billion in transactions and has received aggregate cash consideration of $1.4 billion, including $87 million in July 2016. The $2.65 billion Tenke Fungurume (Tenke) transaction is expected to close in fourth-quarter 2016. In addition, FCX continues to aggressively manage production, exploration and administrative costs and capital spending.

During second-quarter 2016, FCX restructured its oil and gas business to reduce costs and align capital allocation for the business with FCX’s corporate debt reduction initiatives. During the quarter, FCX terminated contracts for Freeport-McMoRan Oil & Gas LLC’s (FM O&G) deepwater drillships, and settled aggregate commitments totaling $1.1 billion for $755 million, of which $540 million was funded with shares of FCX common stock. In addition to the drillship contract savings of approximately $350 million, FCX has identified annual operating and administrative cost savings in excess of $150 million in connection with restructuring efforts.

During 2016, FCX has retired $369 million of its senior notes through a series of privately negotiated exchanges for 28 million shares of its common stock (including $268 million during second-quarter 2016, which resulted in a $39 million gain on early extinguishment of debt). These transactions will reduce annual interest expense by $17 million. FCX will continue to evaluate opportunities for transactions, which may include open-market purchases of its debt, debt for debt exchanges, and privately negotiated exchanges of its debt for equity or equity-linked securities. FCX may also issue additional debt or convertible securities to repay or refinance existing debt. The completion and amount of these transactions, if any, are subject to a number of factors, including market conditions, FCX's financial position and its ability to complete such transactions on economically attractive terms.

With the successful completion of the Cerro Verde expansion and access to higher grade ore from the Grasberg mine in future quarters, FCX expects to generate substantial cash flows over the next 18 months for debt reduction.

As part of its plan to reduce outstanding indebtedness, FCX intends to commence, subject to market conditions, a registered at-the-market offering of up to $1.5 billion of common stock and use the proceeds to retire outstanding indebtedness. FCX believes the proceeds of this offering, together with previously announced asset sale transactions and anticipated cash flow from operations, will enable it to achieve its near-term debt reduction objectives.

While additional asset sales may be considered, FCX remains focused on retaining a high-quality portfolio of long-lived copper assets positioned to generate value as market conditions improve. In addition to debt reduction plans, FCX is pursuing opportunities to create additional value through mine designs that would increase copper reserves, reduce costs and provide opportunities to enhance net present values, and continues to advance studies for future development of its copper resources, the timing of which will be dependent on market conditions.

Following provides a summary of FCX’s completed and pending asset sales (in billions):

Consolidated Sales Volumes

Second-quarter 2016 consolidated copper sales (including Tenke) totaled 1.1 billion pounds, approximately 5 percent below the April 2016 estimate because of lower sales from Indonesia, and were higher than second-quarter 2015 sales of 964 million pounds, primarily reflecting higher volumes from Cerro Verde.

Second-quarter 2016 consolidated gold sales of 156 thousand ounces were lower than the April 2016 estimate of 195 thousand ounces primarily reflecting lower mining rates in Indonesia, and were lower than second-quarter 2015 sales of 352 thousand ounces, primarily reflecting lower ore grades and lower mining and milling rates.

Second-quarter 2016 consolidated molybdenum sales of 19 million pounds approximated the April 2016 estimate and were lower than second-quarter 2015 sales of 23 million pounds, primarily reflecting market-driven curtailed production volumes from the primary molybdenum mines.

Second-quarter 2016 sales from oil and gas operations of 12.4 MMBOE, including 8.65 million barrels (MMBbls) of crude oil, 18.8 billion cubic feet (Bcf) of natural gas and 0.6 MMBbls of natural gas liquids (NGLs), were lower than the April 2016 estimate of 13.5 MMBOE, primarily reflecting lower than anticipated well performance and start-up delays at new wells, and were lower than second-quarter 2015 sales of 13.1 MMBOE, primarily reflecting lower natural gas volumes from Haynesville.

Sales volumes for the year 2016 are expected to approximate 5.0 billion pounds of copper (including 440 million pounds for Tenke through the anticipated closing date), 1.7 million ounces of gold, 76 million pounds of molybdenum and 47.4 MMBOE, including 1.3 billion pounds of copper (including 115 million pounds for Tenke), 410 thousand ounces of gold, 20 million pounds of molybdenum and 11.4 MMBOE for third-quarter 2016. Anticipated higher grades from the Grasberg mine are expected to result in approximately 30 percent of 2016 copper sales and 55 percent of 2016 gold sales to occur in fourth-quarter 2016.

Consolidated Unit Costs

Mining Unit Net Cash Costs. Consolidated average unit net cash costs (net of by-product credits) for FCX's copper mines (including Tenke) of $1.33 per pound of copper in second-quarter 2016 were lower than unit net cash costs of $1.50 per pound in second-quarter 2015, primarily reflecting higher copper sales volumes and the impact of ongoing cost reduction initiatives, partly offset by lower gold and silver credits.

Assuming average prices of $1,300 per ounce of gold and $6 per pound of molybdenum for the second half of 2016 and achievement of current sales volume and cost estimates, consolidated unit net cash costs (net of by-product credits) for copper mines (including Tenke) are expected to average $1.06 per pound of copper for the year 2016. The impact of price changes for the second half of 2016 on consolidated unit net cash costs would approximate $0.015 per pound for each $50 per ounce change in the average price of gold and $0.01 per pound for each $2 per pound change in the average price of molybdenum. Quarterly unit net cash costs vary with fluctuations in sales volumes and realized prices primarily for gold and molybdenum.

Oil and Gas Cash Production Costs per BOE. Cash production costs for oil and gas operations of $15.00 per BOE in second-quarter 2016 were lower than cash production costs of $19.04 per BOE in second-quarter 2015, primarily reflecting higher production from Gulf of Mexico (GOM) wells and ongoing cost reduction efforts.

Based on current sales volume and cost estimates, cash production costs are expected to approximate $15.50 per BOE for the year 2016.

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. In addition to copper, molybdenum concentrate and silver are also produced by certain of FCX's North America copper mines.

All of the North America mining operations are wholly owned, except for Morenci. FCX records its undivided joint venture interest in Morenci using the proportionate consolidation method. On May 31, 2016, FCX completed the sale of an additional 13 percent undivided interest in Morenci for $1.0 billion in cash. As a result of the transaction, FCX's undivided interest in Morenci was prospectively reduced from 85 percent to 72 percent.

Operating and Development Activities. FCX has significant undeveloped reserves and resources in North America and a portfolio of long-term development projects. In the near term, FCX is deferring development of new projects as a result of current market conditions. Future investments will be undertaken based on the results of economic and technical feasibility studies, and market conditions.

During 2015, FCX's revised plans for its North America copper mines to incorporate reductions in mining rates to reduce operating and capital costs. In addition, FCX curtailed operations at the Miami and Tyrone mines and is operating its Sierrita mine at reduced rates. The revised plans at each of the operations incorporate the impacts of lower energy, acid and other consumables, reduced labor costs and a significant reduction in capital spending plans. These operating plans continue to be reviewed and additional adjustments will be made as market conditions warrant.

Operating Data. Following is a summary of consolidated operating data for the North America copper mines for the second quarters and first six months of 2016 and 2015:

North America's consolidated copper sales volumes totaling 464 million pounds in second-quarter 2016 were lower than 486 million pounds in second-quarter 2015 primarily because of timing of sales in the 2015 period. North America copper sales are estimated to approximate 1.8 billion pounds for the year 2016, compared with 2.0 billion pounds in 2015.

Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.40 per pound of copper in second-quarter 2016 were lower than the unit net cash costs of $1.74 per pound in second-quarter 2015, primarily reflecting cost reduction initiatives and lower energy and other input costs.

Average unit net cash costs (net of by-product credits) for the North America copper mines are expected to approximate $1.42 per pound of copper for the year 2016, based on achievement of current sales volume and cost estimates and assuming an average molybdenum price of $6 per pound for the second half of 2016. North America's average unit net cash costs would change by approximately $0.012 per pound for each $2 per pound change in the average price of molybdenum.

South America Mining. FCX operates two copper mines in South America - Cerro Verde in Peru (in which FCX owns a 53.56 percent interest) and El Abra in Chile (in which FCX owns a 51 percent interest). These operations are consolidated in FCX's financial statements. In addition to copper, the Cerro Verde mine produces molybdenum concentrate and silver.

Operating and Development Activities. In September 2015, the Cerro Verde expansion project commenced operations, and achieved capacity operating rates during first-quarter 2016. Cerro Verde's expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies. The project expanded the concentrator facilities from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day and is on track to provide incremental annual production of approximately 600 million pounds of copper and 15 million pounds of molybdenum.

During 2015, FCX revised plans for its South America copper mines, principally to reflect adjustments to the mine plan at El Abra to reduce mining and stacking rates by approximately 50 percent to achieve lower operating and labor costs, defer capital expenditures and extend the life of the existing operations.

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 depend on technical studies, economic factors and global copper market conditions.

Operating Data. Following is a summary of consolidated operating data for the South America mining operations for the second quarters and first six months of 2016 and 2015:

South America's consolidated copper sales volumes of 327 million pounds in second-quarter 2016 were significantly higher than second-quarter 2015 sales of 178 million pounds, primarily reflecting Cerro Verde's expanded operations. Sales from South America mining are expected to approximate 1.36 billion pounds of copper for the year 2016, compared with 871 million pounds of copper in 2015.

Average unit net cash costs (net of by-product credits) for South America mining of $1.31 per pound of copper in second-quarter 2016 were significantly lower than unit net cash costs of $1.90 per pound in second-quarter 2015, primarily reflecting higher copper sales volumes and economies of scale associated with the Cerro Verde expansion. Average unit net cash costs (net of by-product credits) for South America mining are expected to approximate $1.40 per pound of copper for the year 2016, based on current sales volume and cost estimates and assuming average prices of $6 per pound of molybdenum for the second half of 2016.

Indonesia Mining. Through its 90.64 percent owned and consolidated subsidiary PT Freeport Indonesia (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.

Regulatory Matters. In October 2015, the Indonesian government provided a letter of assurance to PT-FI indicating that it will approve the extension of operations beyond 2021, and provide the same rights and the same level of legal and fiscal certainty provided under its current Contract of Work (COW). PT-FI continues to engage in discussions with the Indonesian government to obtain extension of its long-term rights available under the COW.

In connection with its COW negotiations and subject to concluding an agreement to extend PT-FI's operations beyond 2021 on acceptable terms, PT-FI has agreed to construct new smelter capacity in Indonesia and to divest an additional 20.64 percent interest in PT-FI at fair market value.

PT-FI is required to apply for renewal of export permits at six-month intervals. In February 2016, PT-FI's export permit was renewed through August 8, 2016. PT-FI has applied for an extension of this permit. The Indonesian government continues to impose a 5.0 percent export duty while it reviews PT-FI's smelter plans.

Operating and Development Activities. PT-FI's revised operating plans incorporate improved operational efficiencies, reductions in input costs, supplies and contractor costs, foreign exchange impacts and an approximate 20 percent deferral of capital expenditures that had been planned for 2016.

PT-FI has several projects in progress in the Grasberg minerals district related to the development of its large-scale, long-lived, high-grade underground ore bodies. In aggregate, these underground ore bodies are expected to produce large-scale quantities of copper and gold following the transition from the Grasberg open pit, currently anticipated to occur in early 2018. From 2016 to 2020, estimated aggregate capital spending on these projects is currently expected to average $1.0 billion per year ($0.8 billion per year net to PT-FI). Considering the long-term nature and size of these projects, actual costs could vary from these estimates. In response to market conditions and Indonesian regulatory uncertainty, the timing of these expenditures continues to be reviewed.

Operating Data. Following is a summary of consolidated operating data for the Indonesia mining operations for the second quarters and first six months of 2016 and 2015:

Indonesia's consolidated copper sales totaled 196 million pounds in both the second quarters of 2016 and 2015 as higher copper ore grades in the 2016 period were offset by lower mining and milling rates. Indonesia's second-quarter 2016 gold sales of 151 thousand ounces were lower than second-quarter 2015 sales of 346 thousand ounces, primarily reflecting lower gold ore grades and lower mining and milling rates.

During second-quarter 2016, PT-FI completed repairs to its large-scale concentrating facility, which required 23 days of downtime to repair one of the milling circuits. PT-FI’s second-quarter 2016 production was also impacted by lower than expected mining rates and productivity in the Grasberg open pit, which affects the timing of metal production. Productivity in the Grasberg open pit has improved in July.

At the Grasberg mine, the sequencing of mining areas with varying ore grades causes fluctuations in quarterly and annual production of copper and gold. Consolidated sales volumes from Indonesia mining operations are expected to approximate 1.3 billion pounds of copper and 1.7 million ounces of gold for the year 2016, compared with 744 million pounds of copper and 1.2 million ounces of gold for the year 2015. PT-FI expects ore grades to improve significantly, with approximately 40 percent of its 2016 copper sales and 55 percent of its 2016 gold sales anticipated in fourth-quarter 2016.

A significant portion of PT-FI's costs are fixed and unit costs vary depending on volumes and other factors. Indonesia's unit net cash costs (including gold and silver credits) of $1.20 per pound of copper in second-quarter 2016 were higher than unit net cash costs of $0.81 per pound in second-quarter 2015, primarily reflecting lower gold credits, partly offset by lower royalties, export duties and energy costs.

Based on current sales volume and cost estimates, and assuming an average gold price of $1,300 per ounce for the second half of 2016, unit net cash costs (net of gold and silver credits) for Indonesia mining are expected to approximate $0.12 per pound of copper for the year 2016 and $0.43 per pound for third-quarter 2016. Indonesia mining's unit net cash costs for the year 2016 would change by approximately $0.05 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 mining's costs, unit costs vary from quarter to quarter depending on copper and gold volumes. Anticipated higher ore grades from the Grasberg mine are expected to result in lower unit net cash costs in the second half of 2016.

Africa Mining. Africa mining includes the Tenke Fungurume Mining S.A. (TFM) minerals district, in which FCX holds an effective 56 percent interest in the Tenke copper and cobalt mining concessions in the Southeast region of the DRC. In May 2016, FCX entered into a definitive agreement to sell its interest in TF Holdings Limited. As a result and in accordance with accounting guidelines, the operating results of Africa mining have been separately reported as discontinued operations in FCX’s consolidated statements of operations for all periods presented. The transaction is expected to close in fourth-quarter 2016, subject to regulatory approvals, CMOC shareholder approval and other customary closing conditions.

Operating and Development Activities. Revised plans at Tenke incorporate a 50 percent reduction in capital spending for 2016 and various initiatives to reduce operating, administrative and exploration costs. TFM successfully commissioned a sulphuric acid plant in first-quarter 2016, which will reduce requirements for third-party acid purchases.

Operating Data. Following is a summary of operating data for the Africa mining operations for the second quarters and first six months of 2016 and 2015:

Africa mining's copper sales of 124 million pounds in second-quarter 2016 were higher than second-quarter 2015 copper sales of 104 million pounds, primarily reflecting higher mining rates and timing of sales in the 2015 period. Africa mining's sales for 2016 (through the anticipated closing date) are expected to approximate 440 million pounds of copper and 35 million pounds of cobalt, compared with 467 million pounds of copper and 35 million pounds of cobalt for the year 2015.

Africa mining's unit net cash costs (net of cobalt credits) of $1.34 per pound of copper in second-quarter 2016 were higher than unit net cash costs of $1.07 per pound of copper in second-quarter 2015, primarily reflecting lower cobalt credits. Unit net cash costs (net of cobalt credits) for Africa mining are expected to approximate $1.28 per pound of copper for the year 2016, based on current sales volume and cost estimates and assuming an average cobalt price of $11 per pound for the second half of 2016. Africa mining's unit net cash costs for the year 2016 would change by approximately $0.045 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 concentrate, which is typically further processed into value-added molybdenum chemical products. The majority of molybdenum concentrate produced at the Henderson and Climax mines, as well as from FCX's North and South America copper mines, is processed at FCX's conversion facilities.

Operating and Development Activities. In response to market conditions, the revised plans for the Henderson molybdenum mine incorporate lower operating rates, resulting in an approximate 65 percent reduction in Henderson's annual production volumes. FCX also adjusted production plans at its by-product mines, including reduced production at its Sierrita mine. Additionally, FCX incorporated changes in the commercial pricing structure for its chemicals products to promote continuation of chemical-grade production.

Production from the Molybdenum mines totaled 7 million pounds of molybdenum in second-quarter 2016 and 13 million pounds in second-quarter 2015. Refer to summary operating data on page 4 for FCX's consolidated molybdenum sales, which includes sales of molybdenum produced at the Molybdenum mines, and from FCX's North and South America copper mines.

Average unit net cash costs for the Molybdenum mines of $7.80 per pound of molybdenum in second-quarter 2016 were higher than average unit net cash costs of $7.19 per pound in second-quarter 2015, primarily reflecting lower volumes. Based on current sales volume and cost estimates, unit net cash costs for the Molybdenum mines are expected to average approximately $8.60 per pound of molybdenum for the year 2016.

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 schedules, "Product Revenues and Production Costs," beginning on page XV, which are available on FCX's website, "fcx.com."

Mining Exploration Activities. FCX's mining exploration activities are generally associated with its existing mines focusing on opportunities to expand reserves and resources to support development of additional future production capacity. Exploration results continue to indicate opportunities for significant future potential reserve additions in North and South America. Exploration spending continues to be constrained by market conditions and is expected to approximate $45 million for the year 2016.

OIL AND GAS OPERATIONS

Through its wholly owned oil and gas subsidiary, FM O&G, FCX's principal oil and gas assets include significant oil production facilities and growth potential in the Deepwater GOM and established oil production facilities in California. For the first six months of 2016, approximately 90 percent of FCX's oil and gas revenues were from oil and NGLs.

During second-quarter 2016, FM O&G completed the sale of certain oil and gas royalty interests for cash consideration of $102 million (before closing adjustments), and in July 2016, completed the sale of its Haynesville shale assets in North Louisiana for cash consideration of $87 million (before closing adjustments). Under full cost accounting rules, the proceeds from these transactions are recorded as a reduction of capitalized oil and gas properties, with no gain or loss recognition.

Impairment of Oil and Gas Properties. 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 and amortized to expense under the unit-of-production method on a country-by-country basis using estimates of proved oil and gas reserves relating to each country where such activities are conducted. The costs of unproved oil and gas properties are excluded from amortization until the properties are evaluated.

Under full cost accounting rules, a "ceiling test" is conducted each quarter to review the carrying value of oil and gas properties for impairment. The U.S. Securities and Exchange Commission (SEC) requires the twelve-month average of the first-day-of-the-month historical reference oil price be used in determining the ceiling test limitation. Using West Texas Intermediate (WTI) as the reference oil price, the average price was $43.12 per barrel at June 30, 2016, compared with $46.26 per barrel at March 31, 2016. As a result of the impact of the reduction in twelve-month historical prices, net capitalized costs exceeded the ceiling test limitation under full cost accounting rules, which resulted in the recognition of a second-quarter 2016 impairment charge of $291 million.

If the twelve-month historical average price remains below the June 30, 2016, twelve-month average of $43.12 per barrel, the ceiling test limitation will decrease, potentially resulting in additional ceiling test impairments of FCX's oil and gas properties. The WTI spot oil price was $43.13 per barrel at July 25, 2016. In addition to a decline in the trailing twelve-month average oil and gas prices, other factors that could result in future impairment of FCX's oil and gas properties include costs transferred from unevaluated properties to the full cost pool without corresponding proved oil and gas reserve additions, negative reserve revisions and the capitalization of future exploration and development costs. At June 30, 2016, carrying costs for unevaluated properties excluded from amortization totaled $1.7 billion. These costs will be transferred into the full cost pool as the properties are evaluated and proved reserves are established or if impairment is determined. If these activities do not result in additions to discounted future net cash flows from proved oil and gas reserves at least equal to the related costs transferred (net of related tax effects), additional ceiling test impairments may occur.

Financial and Operating Data. Following is a summary of financial and operating data for the U.S. oil and gas operations for the second quarters and first six months of 2016 and 2015:

FM O&G's average realized price for crude oil was $41.10 per barrel in second-quarter 2016 (87 percent of the average Brent crude oil price of $47.03 per barrel). FM O&G's average realized price for natural gas was $2.04 per MMBtu in second-quarter 2016, compared to the New York Mercantile Exchange natural gas price average of $1.95 per MMBtu for the April through June 2016 contracts.

Lower realized revenues for oil and gas operations of $32.70 per BOE in second-quarter 2016, compared to $50.04 per BOE in second-quarter 2015, primarily reflects lower oil prices and the impact of realized cash gains on derivative contracts of $7.73 per BOE in second-quarter 2015.

Cash production costs for oil and gas operations of $15.00 per BOE in second-quarter 2016 were lower than cash production costs of $19.04 per BOE in second-quarter 2015, primarily reflecting higher production from GOM wells and ongoing cost reduction efforts.

Following is a summary of average oil and gas sales volumes per day by region for the second quarters and first six months of 2016 and 2015:

Daily sales volumes averaged 136 MBOE for second-quarter 2016, including 95 thousand barrels (MBbls) of crude oil, 207 million cubic feet (MMcf) of natural gas and 6 MBbls of NGLs. Since year-end 2015, FM O&G has commenced production from six 100-percent-owned Deepwater GOM wells. Oil and gas sales volumes are expected to average 130 MBOE per day for the year 2016, comprised of 73 percent oil, 5 percent natural gas and 22 percent NGLs. These estimates are below the April 2016 estimates of 149 MBOE per day, reflecting revised estimates for three Holstein Deep wells that commenced production in second-quarter 2016, the sale of the Haynesville shale assets and production constraints following a fire at a third-party natural gas processing plant.

In late June 2016, a fire at a third-party natural gas processing plant in Pascagoula, Mississippi resulted in the shutdown of the plant and the pipeline that transports gas supply from several offshore platforms, including FM O&G’s Horn Mountain and Marlin facilities (representing approximately 45 percent of FM O&G's GOM BOE production). As a result, production has been temporarily constrained and FM O&G is currently accessing an alternative pipeline as an interim solution. FM O&G is working with third parties on alternative routes to resume normal production and does not expect long-term impacts from this event.

Based on current sales volume and cost estimates, cash production costs are expected to approximate $15.50 per BOE for the year 2016.

Oil and Gas Exploration, Operating and Development Activities. In second-quarter 2016, FM O&G remained focused on managing costs and enhancing asset values in response to the current market environment. FM O&G achieved a number of important operational milestones during the quarter, including the commencement of production from five 100-percent-owned Deepwater GOM tieback wells, including three at Holstein Deep and two in the Horn Mountain area. At Lucius and Heidelberg, the operator drilled development wells with favorable results that we believe will further benefit future oil production.

During second-quarter 2016, FCX negotiated the termination and settlement of FM O&G's drilling rig contracts with Noble Drilling (U.S.) LLC (Noble) and Rowan Companies plc (Rowan). As a result of the settlements, FM O&G was released from a total of $1.1 billion in payment obligations under its three drilling rig contracts. In aggregate, reductions in previously contracted commitments for deepwater drillships approximate $350 million. During second-quarter 2016, FCX issued 48 million shares of its common stock (representing a value of $540 million) and paid $85 million cash in connection with the settlements. FCX will fund the remaining $130 million in cash during third-quarter 2016. FCX also agreed to provide contingent payments of up to $105 million, depending on the average price of crude oil over the 12-month period ending June 30, 2017. A net charge of $0.6 billion was recorded in second-quarter 2016 associated with the termination of these contracts.

Assuming an average oil price of $49 per barrel, combined with these actions, operating cash flows from the oil and gas business are expected to exceed its capital expenditures in the second half of 2016 and 2017.

Since commencing development activities in 2014 at its three 100-percent-owned production platforms in the Deepwater GOM, FM O&G has drilled 14 wells in producing fields with positive results; 10 of these wells have been brought on production, including five wells during second-quarter 2016.

Oil and Gas Capital Expenditures. Capital expenditures for oil and gas operations in second-quarter 2016 totaled $388 million in the U.S. (including $205 million incurred for GOM and approximately $150 million associated with the change in capital expenditure accruals) and $4 million associated with international oil and gas properties.

Capital expenditures for oil and gas operations for the year 2016 are estimated to total $1.4 billion, with approximately 90 percent of the capital budget expected to be directed to the GOM.

Deepwater GOM. FM O&G operates and owns 100-percent working interests in the Holstein, Marlin and Horn Mountain deepwater production platforms, which in total have processing capacity of 250 MBbls of oil per day. In addition, FM O&G has interests in the Lucius, Heidelberg, Ram Powell and Hoover producing oil fields and the Atwater Valley undeveloped area.

During second-quarter 2016, production from six wells in the Lucius field in the Keathley Canyon area averaged 20 MBOE per day, net to FM O&G’s 25-percent working interest. The field has performed well since initial production commenced in first-quarter 2015. In second-quarter 2016, the operator completed the seventh well in the field. Approximately 80 percent of FM O&G’s working interest is held through its consolidated subsidiary Plains Offshore Operations Inc. (POI). Third parties hold a preferred interest in POI and are entitled to a liquidation preference and to receive preferred distributions.

In January 2016, first oil production commenced from three initial subsea wells in the Heidelberg oil field in the Green Canyon area. Heidelberg is a subsea oil development consisting of five subsea wells tied back to a truss spar hull located in 5,300 feet of water. In second-quarter 2016, the operator commenced drilling a fourth well in the field, and in July 2016, logging results confirmed oil pay with similar characteristics to a good offset producing well. The fifth and final well of the initial development phase commenced drilling in third-quarter 2016. Heidelberg field was discovered in February 2009, and the subsequent development project was sanctioned in early 2013. FM O&G has a 12.5 percent working interest in Heidelberg.

At the 100-percent-owned Holstein Deep, three wells commenced production in second-quarter 2016 and are currently producing at a gross rate of approximately 9 MBOE per day. The rates are below previous estimates, reflecting lower than expected crude oil quality and lower permeability. The Holstein Deep development is located in Green Canyon Block 643, west of the 100-percent-owned Holstein platform in 3,890 feet of water, with production facilities capable of processing 113 MBbls of oil per day.

FM O&G’s 100-percent-owned Horn Mountain field is located in the Mississippi Canyon area and has production facilities capable of processing 75 MBbls of oil per day. The Quebec/Victory and Kilo/Oscar wells commenced production in second-quarter 2016. To enhance recovery of remaining oil in place, future development plans will target subsea tieback from multiple stacked sands in the area.

FM O&G’s well inventory also includes the Horn Mountain Deep discovery well, where successful drilling results in 2015 indicated the presence of sand sections deeper than known pay sections in the field. These positive results and geophysical data support the existence of Middle Miocene reservoir potential for additional development opportunities in the Horn Mountain Deep area, including five 100-percent-owned exploration prospects with significant future potential. FM O&G controls rights to over 55,000 acres associated with these prospects.

FM O&G’s 100-percent-owned Marlin Hub is located in the Mississippi Canyon area and has production facilities capable of processing 60 MBbls of oil per day. FM O&G has drilled five successful tieback opportunities in the area since 2014. The King D-12 and Dorado wells commenced production in 2015, and the King D-13 well commenced production in first-quarter 2016.

CASH FLOWS, CASH and DEBT TRANSACTIONS

Operating Cash Flows. FCX generated operating cash flows of $874 million (including $278 million in working capital sources and changes in other tax payments) for second-quarter 2016 and $1.6 billion (including $466 million in working capital sources and changes in other tax payments) for the first six months of 2016.

Based on current sales volume and cost estimates and assuming average prices of $2.25 per pound of copper, $1,300 per ounce of gold, $6 per pound of molybdenum and $48 per barrel of Brent crude oil for the second half of 2016, FCX's consolidated operating cash flows are estimated to approximate $4.5 billion for the year 2016 (including $0.7 billion in working capital sources and other tax payments). The impact of price changes for the second half of 2016 on operating cash flows would approximate $260 million for each $0.10 per pound change in the average price of copper, $40 million for each $50 per ounce change in the average price of gold, $35 million for each $2 per pound change in the average price of molybdenum and $55 million for each $5 per barrel change in the average Brent crude oil price.

Capital Expenditures. Capital expenditures totaled $833 million for second-quarter 2016, consisting of $441 million for mining operations (including $350 million for major projects) and $392 million for oil and gas operations. Capital expenditures for the first six months of 2016 totaled $1.8 billion, consisting of $900 million for mining operations (including $0.7 billion for major projects) and $915 million for oil and gas operations.

Capital expenditures are expected to approximate $3.1 billion for the year 2016, consisting of $1.7 billion for mining operations (including $1.3 billion for major projects, primarily for underground development activities at Grasberg and remaining costs for the Cerro Verde expansion) and $1.4 billion for oil and gas operations.

Cash. Following is a summary of the U.S. and international components of consolidated cash and cash equivalents available to the parent company (excluding cash and cash equivalents of $78 million in assets held for sale), net of noncontrolling interests' share, taxes and other costs at June 30, 2016 (in millions):

Debt. FCX continues to focus on cost and capital management and cash flow generation from its operations and is taking actions to reduce debt through asset sales, available cash flows and other transactions. Following is a summary of total debt and the related weighted-average interest rates at June 30, 2016 (in billions, except percentages):

At June 30, 2016, FCX had $40 million in letters of credit issued and availability of $3.5 billion under its $3.5 billion revolving credit facility.

Through July 25, 2016, FCX exchanged $369 million in senior notes (including exchanges totaling $268 million in second-quarter 2016) maturing in 2022, 2023, 2034 and 2043 for 28 million shares of FCX common stock in a series of privately negotiated transactions at a cost of $311 million. FCX has approximately 1.33 billion common shares outstanding, which includes shares issued through July 25, 2016, in connection with the settlement of these privately negotiated transactions.
