Consolidated Sales Volumes
Third-quarter 2018 copper sales of 1.04 billion pounds were 8 percent higher than the July 2018 estimate of 970 million pounds and 12 percent higher than third-quarter 2017 sales of 932 million pounds, primarily reflecting higher ore grades and operating rates in Indonesia.
Third-quarter 2018 gold sales of 837 thousand ounces were 20 percent higher than the July 2018 estimate of 700 thousand ounces and more than double third-quarter 2017 sales of 355 thousand ounces, primarily reflecting higher ore grades and operating rates in Indonesia.
Third-quarter 2018 molybdenum sales of 22 million pounds were lower than the July 2018 estimate of 24 million pounds and approximated third-quarter 2017 sales.
Sales volumes for the year 2018 are expected to approximate 3.8 billion pounds of copper, 2.45 million ounces of gold and 95 million pounds of molybdenum, including 790 million pounds of copper, 330 thousand ounces of gold and 25 million pounds of molybdenum in fourth-quarter 2018.
Projections for 2018 and other forward looking statements in this release assume extension of PT-FI’s long-term mining rights or an extension of PT-FI’s temporary special mining license (IUPK) after October 31, 2018.

Consolidated Unit Costs
Consolidated average unit net cash costs (net of by-product credits) for FCX's copper mines of $0.93 per pound of copper in third-quarter 2018 were lower than unit net cash costs of $1.20 per pound in third-quarter 2017, primarily reflecting higher by-product credits, partly offset by nonrecurring charges associated with Cerro Verde's new three-year CLA.
Assuming average prices of $1,200 per ounce of gold and $12.00 per pound of molybdenum for fourth-quarter 2018 and achievement of current sales volume and cost estimates, consolidated unit net cash costs (net of by-product credits) for copper mines are expected to average $1.06 per pound of copper for the year 2018 (including $1.45 per pound of copper in fourth-quarter 2018). The impact of price changes for fourth-quarter 2018 on consolidated unit net cash costs would approximate $0.01 per pound for each $50 per ounce change in the average price of gold and $0.005 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.
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, certain of FCX's North America copper mines produce molybdenum concentrate, gold and silver. All of the North America mining operations are wholly owned, except for Morenci. FCX records its 72 percent undivided joint venture interest in Morenci using the proportionate consolidation method.
Operating and Development Activities. FCX has significant undeveloped reserves and resources in North America and a portfolio of potential long-term development projects. Future investments will be undertaken based on the results of economic and technical feasibility studies, and are dependent on market conditions. FCX continues to study opportunities to reduce the capital intensity of its potential long-term development projects.
Through exploration drilling, FCX has identified a significant resource at its wholly owned Lone Star project located near the Safford operation in eastern Arizona. An initial project to develop the Lone Star oxide ores commenced in first-quarter 2018, with first production expected by the end of 2020. Total capital costs, including mine equipment and pre-production stripping, are expected to approximate $850 million and will benefit from the utilization of existing infrastructure at the adjacent Safford operation. As of September 30, 2018, approximately $200 million has been incurred for this project. Production from the Lone Star oxide ores is expected to average approximately 200 million pounds of copper per year with an approximate 20-year mine life. The project also advances exposure to a significant sulfide resource. FCX continues to advance drilling activities to define future large-scale development opportunities in the Lone Star/Safford minerals district.

North America's consolidated copper sales volumes totaled 350 million pounds in third-quarter 2018 and 347 million pounds in third-quarter 2017. North America copper sales are estimated to approximate 1.4 billion pounds for the year 2018, compared with 1.5 billion pounds in 2017.
Average unit net cash costs (net of by-product credits) for the North America copper mines of $1.82 per pound of copper in third-quarter 2018 were higher than unit net cash costs of $1.59 per pound in third-quarter 2017, primarily reflecting increased mining rates and higher mining and milling costs.
Average unit net cash costs (net of by-product credits) for the North America copper mines are expected to approximate $1.78 per pound of copper for the year 2018, based on achievement of current sales volume and cost estimates and assuming an average molybdenum price of $12.00 per pound for fourth-quarter 2018. North America's average unit net cash costs for the year 2018 would change by approximately $0.01 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. Cerro Verde's expanded operations benefit from its large-scale, long-lived reserves and cost efficiencies. The Cerro Verde expansion project, which achieved capacity operating rates in early 2016, expanded the concentrator facilities' capacity from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day. During 2018, Cerro Verde received a modified environmental permit allowing it to operate its existing concentrator facilities at rates up to 409,500 metric tons of ore per day. Cerro Verde's concentrator facilities have continued to perform well, with average mill throughput rates of 384,800 metric tons of ore per day for the first nine months of 2018.
FCX continues to evaluate a large-scale expansion at El Abra to process additional sulfide material and to achieve higher recoveries. El Abra's large sulfide resource could potentially support a major mill project similar to

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 concentrate that contains significant quantities of gold and silver.
Regulatory Matters. On September 27, 2018, FCX, PT-FI, PT Indocopper Investama (PT-II) and PT Inalum entered into a Divestment Agreement on previously agreed economic terms in connection with PT Inalum’s acquisition of shares of PT-FI. Under the Divestment Agreement, PT Inalum will acquire, for cash consideration of $350 million, 100 percent of FCX's interests in PT-II, which owns 9.36 percent of PT-FI (equates to a 5.6 percent interest after 2022). PT Inalum also entered into a definitive agreement with Rio Tinto to acquire for cash consideration of $3.5 billion, all of Rio Tinto's interests (40 percent interest after 2022) associated with its joint venture with PT-FI (the Joint Venture).
The arrangements provide for FCX and existing PT-FI shareholders to retain the economics of the revenue and cost sharing arrangements under the Joint Venture and for FCX to continue to manage PT-FI's operations. Following completion of the transaction, which includes Rio Tinto's interest being merged into PT-FI, PT-FI will have an expanded asset base and PT Inalum's share ownership will be 51.2 percent of PT-FI (subject to a dividend assignment mechanism to replicate the Joint Venture economics), and FCX's ownership will be 48.8 percent.
Concurrent with the closing of the divestment transaction, PT-FI will be granted an IUPK providing long-term mining rights with assured legal and fiscal terms and legal enforceability through 2041. PT-FI has agreed to construct a smelter within five years of the closing with economics shared pro rata by FCX and PT Inalum according to their respective equity ownership in PT-FI.
The transaction, which is expected to close in late 2018 or early 2019, is subject to certain conditions, including the issuance of the IUPK in a form acceptable to FCX and PT Inalum; resolution of environmental regulatory matters satisfactory to the Indonesian government, FCX and PT Inalum; various other Indonesian regulatory actions and approvals; and receipt of customary approvals from international competition authorities.
PT-FI's export license is effective through February 15, 2019, and PT-FI's temporary IUPK is effective through October 31, 2018. PT-FI will continue to seek extensions to its temporary IUPK until closing of the pending transaction. Until the pending transaction is completed, PT-FI has reserved all rights under its Contract of Work (COW).
Operating and Development Activities. PT-FI is currently mining the final phase of the Grasberg open pit, which contains high copper and gold ore grades. Following results of an economic analysis in the first half of 2018, PT-FI revised its mine plans to continue to mine ore from the open pit until transitioning to the Grasberg Block Cave (GBC) underground mine in the first half of 2019.
PT-FI has several projects 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.
Substantial progress has been made to prepare for the transition to mining of the GBC underground mine. First undercut blasting occurred in September 2018, and cave production is scheduled for the first half of 2019. All underground mining levels and the ore flow system are being commissioned. Production rates over the next five years are expected to ramp up to 130,000 metric tons of ore per day.
During second-quarter 2018, PT-FI initiated plans to conduct hydraulic fracturing activities to manage rock stresses and pre-condition the Deep Mill Level Zone (DMLZ) underground mine for large-scale production following mining induced seismic activity experienced in 2017 and 2018. Hydraulic fracturing activities designed to safely manage production commenced in third-quarter 2018 and to date have accomplished expected results. PT-FI's revised mine plans for the DMLZ underground mine, which continue to be reviewed, currently project block cave mining activities in the DMLZ underground mine to commence in mid-2019. PT-FI expects the DMLZ to reach full production rates of 80,000 metric tons per day in 2022. Estimates of timing of future production continue to be reviewed and may be modified as additional information becomes available.

PT-FI's estimated annual capital spending on underground mine development projects is expected to average $0.8 billion per year ($0.7 billion per year net to PT-FI) over the next five years. Considering the long-term nature and size of these projects, actual costs could vary from these estimates.
PT-FI is also evaluating plans for the development of a new copper smelter in Indonesia, including site selection, engineering, joint venture and financing arrangements.
Operating Data. Following is summary consolidated operating data for the Indonesia mining operations for the third quarters and first nine months of 2018 and 2017:

a. | For a reconciliation of unit net cash (credits) 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 XII, which are available on FCX's website, "fcx.com."

b. | Excludes fixed costs charged directly to production and delivery costs totaling $0.03 per pound of copper in third-quarter 2017 and $0.18 per pound of copper for the first nine months of 2017 associated with workforce reductions. Refer to the supplemental schedule, “Adjusted Net Income,” on page VII, which is available on FCX’s website, “fcx.com,” for a summary of these charges.

Indonesia's consolidated sales of 368 million pounds of copper and 831 thousand ounces of gold in third-quarter 2018 were higher than third-quarter 2017 sales of 258 million pounds of copper and 352 thousand ounces of gold, primarily reflecting higher operating rates and ore grades.
Assuming achievement of planned operating rates for fourth-quarter 2018, consolidated sales volumes from Indonesia mining are expected to approximate 1.16 billion pounds of copper and 2.45 million ounces of gold for the year 2018, compared with 1.0 billion pounds of copper and 1.5 million ounces of gold for the year 2017.
As PT-FI transitions mining from the open pit to underground, its production is expected to be significantly lower in 2019 and 2020, compared to 2018. Metal production is expected to improve significantly by 2021 following a ramp-up period.
A significant portion of PT-FI's costs are fixed and unit costs vary depending on production volumes and other factors. As a result of higher sales volumes and gold and silver credits, Indonesia had unit net cash credits (including gold and silver credits) of $0.72 per pound of copper in third-quarter 2018, compared with unit net cash costs of $0.13 per pound in third-quarter 2017.

Freeport-McMoRan |  | 8

Assuming an average gold price of $1,200 per ounce for fourth-quarter 2018 and achievement of current sales volume and cost estimates, unit net cash credits (including gold and silver credits) for Indonesia mining are expected to approximate $0.54 per pound of copper for the year 2018 (including unit net cash costs of $0.48 per pound of copper in fourth-quarter 2018). Indonesia mining's unit net cash credits for the year 2018 would change by approximately $0.03 per pound for each $50 per ounce change in the average price of gold for fourth-quarter 2018. Because of the fixed nature of a large portion of Indonesia's costs, unit net cash credits/costs vary from quarter to quarter depending on copper and gold volumes.
Indonesia mining's projected sales volumes and unit net cash credits for the year 2018 are dependent on a number of factors, including operational performance, workforce productivity, timing of shipments, and Indonesia regulatory matters, including extension of PT-FI's long-term mining rights or an extension of PT-FI's temporary IUPK after October 31, 2018.
Molybdenum Mines. FCX has two wholly owned molybdenum mines - 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 America and South America copper mines, is processed at FCX's conversion facilities.
Operating and Development Activities. Production from the Molybdenum mines totaled 8 million pounds of molybdenum in both third-quarter 2018 and third-quarter 2017. Refer to summary operating data on page 3 for FCX's consolidated molybdenum sales and average realized prices, which includes sales of molybdenum produced at the Molybdenum mines, and from FCX's North America and South America copper mines.
Unit net cash costs for the Molybdenum mines averaged $9.02 per pound of molybdenum in third-quarter 2018 and $7.82 per pound in third-quarter 2017. Based on current sales volume and cost estimates, average unit net cash costs for the Molybdenum mines are expected to approximate $8.80 per pound of molybdenum for the year 2018.
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 XII, 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. A drilling program to further delineate the Lone Star resource continues to indicate significant additional mineralization in this district, with higher ore grades than FCX's other North America copper mines. Exploration results continue to indicate opportunities for significant future potential reserve additions in North America and South America. Exploration spending is expected to approximate $85 million for the year 2018.
CASH FLOWS, CASH and DEBT
Operating Cash Flows. FCX generated operating cash flows of $1.25 billion in third-quarter 2018 and $3.9 billion for the first nine months of 2018.
Based on current sales volume and cost estimates, and assuming average prices of $2.85 per pound of copper, $1,200 per ounce of gold and $12.00 per pound of molybdenum for fourth-quarter 2018, FCX's consolidated operating cash flows are estimated to approximate $4.2 billion for the year 2018 (net of $0.5 billion in working capital uses and timing of other tax payments). The impact of price changes during fourth-quarter 2018 on operating cash flows would approximate $105 million for each $0.10 per pound change in the average price of copper, $15 million for each $50 per ounce change in the average price of gold and $15 million for each $2 per pound change in the average price of molybdenum.
Capital Expenditures. Capital expenditures totaled $0.5 billion in third-quarter 2018 (including approximately $0.4 billion for major mining projects) and $1.4 billion for the first nine months of 2018 (including approximately $0.9 billion for major mining projects). Capital expenditures are expected to approximate $2.0 billion for the year 2018, including $1.2 billion for major mining projects primarily associated with underground development activities in the Grasberg minerals district and development of the Lone Star oxide project.

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

b. | Includes net tax (charges) credits of $(10) million in third-quarter 2017 and $21 million for the first nine months of 2017 associated with anticipated recovery of alternative minimum tax credit carryforwards.

c. | Reflects tax charges of $127 million for disputed royalties and other related mining taxes for the period October 2011 through the year 2013, mostly offset by a tax benefit of $125 million associated with disputed royalties and other related mining taxes for the period December 2006 through the year 2013. Refer to the supplemental schedule, "Adjusted Net Income," on page VII, for a summary of charges related to disputed royalties at Cerro Verde.

d. | In accordance with applicable accounting rules, FCX adjusts its interim provision for income taxes equal to its consolidated tax rate.

e. | Includes a tax credit of $5 million associated with the settlement of a state income tax examination.

f. | The consolidated effective income tax rate is a function of the combined effective tax rates for the jurisdictions in which FCX 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 $2.85 per pound for copper, $1,200 per ounce for gold and $12.00 per pound for molybdenum for fourth-quarter 2018, FCX estimates its consolidated effective tax rate for the year 2018 would approximate 37 percent and would decrease with higher prices.

DERIVATIVE INSTRUMENTS
For the first nine months of 2018, FCX's mined copper was sold 60 percent in concentrate, 20 percent as cathode and 20 percent as rod from North America operations. Substantially all of FCX's copper concentrate and cathode sales contracts provide final pricing in a specified future month (generally one to four months from the shipment date) based primarily on quoted London Metal Exchange (LME) monthly average copper prices. FCX records revenues and invoices customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on provisionally priced concentrate and cathode sales that is adjusted to fair value through earnings each period, using the period-end forward prices, until final pricing on the date of settlement. LME copper settlement prices averaged $2.77 per pound during third-quarter 2018 and settled at $2.80 per pound on September 30, 2018. 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 the average recorded copper price for the period. FCX's average realized copper price was $2.80 per pound in third-quarter 2018.

a. | Reflects adjustments to prior period provisionally priced copper sales (i.e., provisionally priced copper sales at December 31, 2017 and 2016).

b. | Reflects adjustments to provisionally priced copper sales for the first nine months of 2018 and 2017.

At September 30, 2018, FCX had provisionally priced copper sales at its copper mining operations totaling 373 million pounds of copper (net of intercompany sales and noncontrolling interests) recorded at an average of $2.84 per pound, subject to final pricing over the next several months. FCX estimates that each $0.05 change in the price realized from the September 30, 2018, provisional price recorded would have an approximate $11 million effect on 2018 net income attributable to common stock. The LME copper price settled at $2.80 per pound on October 23, 2018.
DEFERRED PROFITS
FCX defers recognizing profits on sales from its mining operations to Atlantic Copper and on 25 percent of PT-FI's sales to PT Smelting (PT-FI's 25 percent-owned Indonesian smelting unit) until final sales to third parties occur. Changes in these deferrals attributable to variability in intercompany volumes resulted in net (reductions) additions to net income attributable to common stock totaling $(24) million in third-quarter 2018, $24 million in third-quarter 2017, $(4) million for the first nine months of 2018 and less than $1 million for the first nine months of 2017. 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 $85 million at September 30, 2018. 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
FCX has organized its mining operations into four primary divisions – North America copper mines, South America mining, Indonesia mining and Molybdenum mines, and operating segments that meet certain thresholds are reportable segments. Separately disclosed in the following tables are FCX's reportable segments, which include the Morenci, Cerro Verde and Grasberg (Indonesia Mining) copper mines, the Rod & Refining operations and Atlantic Copper Smelting & Refining.
Intersegment sales between FCX’s business segments are based on terms similar to 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, the timing of sales to unaffiliated customers and transportation premiums.
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 (included in Corporate, Other & Eliminations), 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 individual segments. Accordingly, the following segment information reflects management determinations that may not be indicative of what the actual financial performance of each operating division or segment would be if it was an independent entity.

PRODUCT REVENUES AND PRODUCTION COSTS
Unit net cash costs (credits) 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. GAAP and should not be considered in isolation or as a substitute for measures of performance determined in accordance with U.S. GAAP. These measures are 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 and (iv) it is the method used by FCX's management and Board to monitor FCX's mining operations and to compare mining operations in certain industry publications. 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, which are removed from site production and delivery costs in the calculation of unit net cash (credits) costs, consist of items such as stock-based compensation costs, start-up costs, inventory adjustments, long-lived asset impairments, restructuring and/or unusual charges. 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.
