      "prior_body": "Our operations are subject to extensive and complex laws and regulations, including environmental laws and regulations governing the generation, storage, treatment, transportation and disposal of hazardous substances; solid waste disposal; air emissions; wastewater discharges; remediation, restoration and reclamation of environmental contamination, including mine closures and reclamation; protection of endangered and threatened species and designation of critical habitats; and other related matters. In addition, we must obtain regulatory permits and approvals to start, continue and expand operations. As a mining company, compliance with environmental, health and safety laws and regulations is an integral and costly part of our business. We conduct our operations in a manner that aims to protect public health and the environment, and we believe our operations are in compliance with applicable laws and regulations in all material respects. At December 31, 2022, we had $1.7 billion recorded in our consolidated balance sheet for environmental obligations and $3.0 billion recorded for asset reclamation obligations. We incurred environmental capital expenditures and other environmental costs (including our joint venture partners’ shares) to comply with applicable environmental laws and regulations that affect our operations totaling $0.4 billion in 2022 and $0.3 billion in both 2021 and 2020. For 2023, we expect to incur approximately $0.6 billion of aggregate environmental capital expenditures and other environmental costs. The timing and amounts of estimated payments could change as a result of changes in regulatory requirements, changes in scope and costs of reclamation activities, the settlement of environmental matters and the rate at which actual spending occurs on continuing matters. United States. Laws such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA) and similar state laws may expose us to joint and several liability for environmental damages caused by our operations, or by previous owners or operators of properties we acquired or are currently operating or at sites where we previously sent materials for processing, recycling or disposal. We have substantial obligations for environmental remediation on mining properties previously owned or operated by FMC and certain of its affiliates. We are required by U.S. federal and state laws and regulations to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans for our mining properties if we are unable to do so. Most of our financial assurance obligations are imposed by state laws that vary significantly by jurisdiction, depending on how each state regulates land use and groundwater quality. The U.S. Environmental Protection Agency (EPA) and state agencies may also require financial assurance for investigation and remediation actions that are required under settlements of enforcement actions under CERCLA or similar state laws. Regulations have been considered at various governmental levels to increase financial responsibility requirements both for mine closure and reclamation. In 2019, legislation was enacted in Colorado that eliminates our ability to use 6 6 6 6 6 6 Table of Contents Table of Contents Table of Contents parent company guarantees and requires proof of an end date for water treatment as a condition of permit issuance authorizing mining operations, with some exceptions for existing operations. In 2018, EPA concluded a rulemaking that considered the need for financial responsibility for hardrock mining operations under CERCLA by publishing its determination that it did not intend to require financial responsibility for the hardrock mining industry sector. In 2019, the District of Columbia Circuit upheld the EPA’s decision. In connection with the presidential executive order issued on January 20, 2021, EPA will review this final action, though the timing of its review is unknown. During 2022, in connection with a presidential executive order issued on February 24, 2021, the Federal government established an Interagency Working Group (IWG) led by the Department of Interior (DOI) with expertise in mine permitting and environmental law “to identify gaps in statutes and regulations that may need to be updated to ensure new production meets strong environmental standards throughout the lifecycle of the project.” During 2022, the IWG received more than 31,600 comments in response to multiple questions in a request for information regarding possible changes to legislation, regulation and policies that affect the mining sector. Financial assurance as well as environmental requirements governing hardrock mining continue to be key topics in comments to DOI. Our U.S. mining operations are also subject to regulations under the Endangered Species Act that are intended to protect species listed by the DOI’s Fish & Wildlife Service (FWS) as endangered or threatened, along with critical habitat designated by FWS for these listed species. The regulations may affect the ability of landowners, including us, to obtain federal permits or authorizations needed for expansion of our operations, and may also affect our ability to obtain, retain or deliver water to some operations. New or revised environmental regulatory requirements are frequently proposed, many of which result in substantially increased costs for our business, including those regarding financial assurance discussed above and in Item 1A. “Risk Factors.” For example, our Miami, Arizona, smelter processes a significant portion of the copper concentrate produced by our North America copper mines. In 2022, EPA proposed to revise the standards for hazardous air pollutants from primary copper smelters and is now in the process of considering comments and collecting additional data. EPA may issue a new proposal after considering these comments and data, and any proposal could impose additional requirements on our operations. We may be required to modify our systems or install additional equipment to address findings, new requirements or for other reasons, which could result in significant costs, including increased capital expenditures and operating costs, and could adversely impact our business. EPA and state agencies continue to consider regulations for man-made organic compounds that could be present in soil, groundwater and surface water at our existing and former operations. These regulations may include drinking water standards, hazardous waste requirements, and hazardous substance designations for Perfluorooctanesulfonic and Perfluorooctanoic acids. EPA is also considering how to reduce lead exposure in the environment under multiple environmental programs. Certain federal and state health agencies also support more stringent lead cleanup levels. EPA expects to make substantial progress on these proposals in 2023, and changes to EPA’s lead cleanup levels could result in material increases to our environmental reserves for ongoing residential property cleanup projects near former smelter sites. On January 18, 2023, the final revised definition of the “waters of the United States” issued by EPA and U.S. Army Corps of Engineers was published. The final rule emphasizes a case-by-case approach to “waters of the United States” for tributaries and may impose significant additional restrictions on land uses in remote and arid areas. Although court decisions can affect the scope of the final rule and legal challenges have already been filed, we will likely need federal authorization under the Clean Water Act to expand some of our operations. For information about environmental laws and regulations, litigation and related costs, and reclamation matters related to our North America operations, refer to “Mining Operations” below, Item 1A. “Risk Factors,” Item 3 “Legal Proceedings” and Notes 1 and 12. South America. Peru. In 2005, Peru enacted the General Environmental Law (Law No. 28611), which establishes the main environmental guidelines and principles applicable in Peru. Pursuant to the General Environmental Law, Ministry of Energy and Mines (MINEM) issued national environmental regulations, which have gradually replaced prior guidelines governing governmental agencies environmental competencies. The Environmental Evaluation and Oversight Agency has the authority to inspect mining operations and fine companies that fail to comply with prescribed environmental regulations and their approved environmental assessments. 7 7 7 7 7 7 Table of Contents Table of Contents Table of Contents Cerro Verde is subject to regulation under the Mine Closure Law administered by MINEM. Under the closure regulations, mines must submit a closure plan that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and post-closure plans, and financial assurance. In compliance with the requirement for five-year updates, Cerro Verde is preparing to submit its updated closure plan and cost estimate in February 2023. The Cerro Verde mine has developed and continues to implement detailed, comprehensive mine waste and tailings management programs to meet the applicable Peru waste regulations and our environmental management practices. These programs incorporate commitments included in the Environmental and Social Impact Studies and the Engineer of Record designs, for the specific cases of tailings storage facilities and certain leach pad stockpiles. The site also follows our Tailings Management Policy, which outlines our continued commitment to managing tailings responsibly and addresses the implementation of the Global Industry Standard on Tailings Management for the tailings storage facilities. For information about environmental laws and regulations and reclamation matters related to our Peru operations refer to “Mining Operations” below, Item 1A. “Risk Factors” and Note 12. Chile. El Abra is subject to regulation under the Mine Closure Law administered by the Chile Mining and Geology Agency. In compliance with the requirement for five-year updates, in November 2018, El Abra submitted an updated plan with closure cost estimates based on the existing approved closure plan. Approval of the updated closure plan and cost estimates was received in August 2020, and did not result in a material increase to closure costs. For information about environmental laws and regulations and reclamation matters related to our Chile operations refer to refer to Item 1A. “Risk Factors” and Note 12. Indonesia. PT-FI holds multiple permits from national, provincial, and regency regulatory agencies, including groundwater use permits, effluent and air discharge permits, solid and hazardous waste storage and management permits and protection of forest borrow-to-use permits. Where permits have specific terms, renewal applications are made to the relevant regulatory authority as required, prior to the end of the permit term. In December 2018, Indonesia’s Ministry of Environment and Forestry (MOEF) issued a revised environmental permit to PT-FI to address certain operational activities that it alleged were inconsistent with earlier studies. PT-FI and the MOEF also established a new framework known as the Tailings Management Roadmap for continuous improvement in environmental practices at PT-FI’s operations, including initiatives that will examine options to potentially increase tailings retention and to evaluate large scale beneficial uses of tailings within Indonesia. The third-party expert nominated by MOEF to perform the framework evaluation submitted its report to the MOEF in June 2021. In 2022, PT-FI continued to work with MOEF on the Tailings Management Roadmap objectives. This included further reduction of non-tailings sediment entering the tailings management area, construction of permeable groins in the estuary portion of the tailings management area to increase sedimentation and reduce erosion, as well as continue pursuing beneficial uses of tailings in infrastructure and other projects. Permitting continues to progress for certain facilities related to the expansion of underground mining production operations as well as for additional protection structures necessary to continue to contain the tailings within the approved lowlands tailings management areas. In 2020, PT-FI initiated a new environmental impact analysis (called an Analisis Mengenai Dampak Lingkungan or AMDAL) in preparation for the proposed activities associated with the transition from Grasberg surface to underground operations. PT-FI continues to work with the MOEF to complete the approval requirements of the AMDAL, which is currently estimated to be received in 2023. PT-FI has completed the initial regulatory review of technical approvals associated with the current AMDAL filing and is now undergoing AMDAL Commission review and public consultations. A detailed mine closure plan and 5-year reclamation plan have been approved by Indonesia regulators as required by Indonesia law. The plans are reviewed annually and revised every five years. Required reclamation bonds are in place. In the future, additional approval will be required for the diversion of the Aghawagon/Otomona River out of the tailings management area at the end of mine life. In 2019, PT-FI completed and received approval on an updated mine closure plan to reflect Grasberg minerals district production operations until 2041. PT-FI has complied with the annual renewal of the financial guarantees corresponding to the closure plan.

      "prior_body": "In many of the jurisdictions in which we operate, governmental bodies are increasingly enacting legislation and regulations in response to the potential impacts of climate change. For example, as a result of the 2015 Paris Agreement, a number of governments, including the U.S., have pledged “Nationally Determined Contributions” to control and reduce greenhouse gas emissions (GHG). Additionally, the pledges made as part of the 2021 Glasgow Climate Pact could result in further policy changes in many of the jurisdictions in which we operate. Further, several states in the U.S., including Colorado and New Mexico, have advanced goals reducing or eliminating fossil fuel-based energy production. Carbon tax legislation also has been adopted in jurisdictions where we operate, including Indonesia, and we expect that such carbon taxes and other carbon pricing mechanisms will increase over time. Further, in March 2021, the SEC proposed new climate-related disclosure rules, which if finalized as expected in 2023, would require new climate-related disclosures in SEC filings and audited financial statements, including certain climate-related metrics and GHG emissions data, information about climate-related targets and goals, transition plans, if any, and attestation requirements. While it is not yet possible to reasonably estimate the nature, extent, timing and cost or other impacts of any future carbon pricing mechanisms, other climate change regulatory programs or future legislative action that may be enacted, we anticipate that we will dedicate more resources and money to comply and remediate in response to legislative or regulatory changes.

Water for our Cerro Verde operation in Peru comes from renewable sources through a series of storage reservoirs on the Rio Chili watershed that collects water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant constructed by us. Ongoing El Niño weather patterns have contributed to ongoing drought conditions in the area and water shortages at our Cerro Verde operation are possible, which could impact our operations. Water for our El Abra mining operation in Chile currently comes from the continued pumping of groundwater from the Salar de Ascotán aquifer. The agreement to pump from this aquifer is subject to continued monitoring through 2029 of the aquifer water levels and select flora species to ensure that environmentally sensitive areas are not impacted by our pumping, which if impacted could cause reductions in pumping to restore water levels and could have an adverse effect on production from El Abra. Our permit for pumping of groundwater will expire in 2029 and any renewal may be challenging. We are evaluating water infrastructure alternatives to provide options to extend existing operations and support a future expansion, while continuing to monitor Chile’s regulatory and fiscal matters, as well as trends in capital costs for similar projects. In parallel, as part of the permitting process for the potential expansion, we are planning for a potential submission of an environmental impact statement during 2025, subject to ongoing stakeholder engagement and economic evaluations.

Construction progress of the Manyar smelter (with a capacity to process approximately 1.7 million metric tons of copper concentrate per year) is advancing on schedule with a target of May 2024 for mechanical completion, which will be followed by a ramp-up period through December 2024. Construction of the smelter has an estimated cost of $3.0 billion, including $2.8 billion for a construction contract (excluding capitalized interest, owner’s costs and commissioning) and $0.2 billion for investment in a desalination plant. The PMR is being constructed to process gold and silver from the Manyar smelter and PT Smelting. Construction is in progress with commissioning expected during 2024. Current cost estimates total $665 million, reflecting updated costs for construction, materials, labor and engineering. Atlantic Copper. Our wholly owned Atlantic Copper smelter and refinery is located on land concessions from the Huelva, Spain, port authorities, which are scheduled to expire in 2038. The design capacity of the smelter is approximately 300,000 metric tons of copper per year, and the refinery has a capacity of 286,000 metric tons of copper per year. Atlantic Copper’s anode production from its smelter totaled 261,900 metric tons of copper in 2023, 215,000 metric tons in 2022 and 278,600 metric tons in 2021. Copper cathode production from its refinery totaled 260,300 metric tons of copper in 2023, 218,400 metric tons in 2022 and 277,000 metric tons in 2021. During 2023, Atlantic Copper purchased 40% of its concentrate from our copper mining operations (20% from PT-FI, 17% from South America mining and 3% from the North America copper mines) and 60% from third parties. Atlantic Copper completed a 78-day major maintenance turnaround in 2022. Atlantic Copper’s major maintenance turnarounds typically occur approximately every eight years, with shorter-term maintenance turnarounds in the interim. Atlantic Copper is developing an e-material recycling project as a result of the significant and continued growth in electronic waste material. Atlantic Copper’s existing smelting and refining facilities provide synergies to recycle this type of material, and the project, which is expected to commence operations in 2025, would include an addition of a smelting furnace and associated equipment to recover copper, gold, silver, palladium, tin, nickel and platinum from electronic materials. Atlantic Copper estimates that the initial project capital will approximate $345 million. PT Smelting. PT Smelting, an Indonesia company, owns a copper smelter and refinery in Gresik, Indonesia. On April 30, 2021, PT-FI acquired an additional 14.5% of the outstanding common stock of PT Smelting, increasing its ownership interest to 39.5%. Mitsubishi Materials Corporation (MMC) owns the remaining 60.5% and serves as the operator of PT Smelting. In November 2021, PT-FI completed agreements with MMC to implement the expansion of PT Smelting’s capacity by 30% to 1.3 million metric tons of copper concentrate per year. In December 2023, the project was successfully completed on time and within budget. The project was funded by PT-FI with borrowings that are expected to convert to equity in 2024, increasing PT-FI’s ownership in PT Smelting to approximately 65%. Refer to Note 3 for further discussion. Beginning in 2023, PT-FI’s commercial arrangement with PT Smelting changed from a copper concentrate sales agreement to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee (which PT-FI records as production costs in the consolidated statements of income) to smelt and refine its copper concentrate and PT-FI retains title to all products for sale to unaffiliated third parties (i.e., there are no further sales to PT Smelting). Refer to MD&A and Note 3 for further discussion. PT Smelting’s anode production from its smelter totaled 251,300 metric tons of copper in 2023, 316,700 metric tons in 2022 and 280,400 metric tons in 2021. Copper cathode production from its refinery totaled 212,000 metric tons of copper in 2023, 268,400 metric tons in 2022 and 256,900 metric tons in 2021. PT Smelting’s major scheduled maintenance turnarounds (which approximate 30 days to complete) are expected to occur every two years, with short-term maintenance turnarounds in the interim. PT Smelting completed an 18-day maintenance turnaround during October 2022, a 72-day shutdown in July 2023 associated with its expansion 25 25 25 25 25 25 Table of Contents Table of Contents Table of Contents project and a 7-day shutdown in November 2023 to complete final tie-in of the expansion project. The next maintenance turnaround is scheduled for mid-year 2025. Miami Smelter. We own and operate a smelter at our Miami mining operation in Arizona. The smelter has been operating for over 100 years and has been upgraded numerous times during that period to implement new technologies, improve production and comply with air quality requirements. The Miami smelter processes copper concentrate primarily from our North America copper mines. Concentrate processed through the smelter totaled 810,900 metric tons in 2023, 781,000 metric tons in 2022 and 674,000 metric tons in 2021, and copper anode production from the smelter totaled 222,000 metric tons in 2023, 202,000 metric tons in 2022 and 194,000 metric tons in 2021. In addition, because sulfuric acid is a by-product of smelting concentrate, the Miami smelter is also the most significant source of sulfuric acid for our North America leaching operations. Major maintenance turnarounds are anticipated to occur approximately every three years for the Miami smelter. We performed a major maintenance turnaround during 2021. The next major maintenance turnaround is scheduled for mid-year 2025. Rod & Refining Operations. Our Rod & Refining operations consist of conversion facilities located in North America, including a refinery in El Paso, Texas, and rod mills in El Paso, Texas and Miami, Arizona. We refine our copper anode production from our Miami smelter at our El Paso refinery. The El Paso refinery has the potential to operate at an annual production capacity of approximately 410,000 metric tons of copper cathode, which is sufficient to refine all of the copper anode we produce at our Miami smelter. Copper cathode production from the El Paso refinery totaled 217,800 metric tons in 2023, 208,900 metric tons in 2022 and 187,300 metric tons in 2021. Our El Paso refinery also produces nickel carbonate, copper telluride and autoclaved slimes material containing gold, silver, platinum and palladium. Molybdenum Conversion Facilities. We process molybdenum concentrate at our conversion plants in the U.S. and Europe into such products as technical-grade molybdic oxide, ferromolybdenum, pure molybdic oxide, ammonium molybdates and molybdenum disulfide. We operate molybdenum roasters in Sierrita, Arizona; Fort Madison, Iowa; and Rotterdam, the Netherlands, and we operate a molybdenum pressure-leach plant in Bagdad, Arizona. We also produce ferromolybdenum for customers worldwide at our conversion plant located in Stowmarket, United Kingdom. Other North America Copper Mines. We have five non-operating copper mines – Ajo, Bisbee, Tohono, Twin Buttes and Christmas, which are located in Arizona – that have been on care and maintenance status for several years and would require new or updated environmental studies, new permits, and additional capital investment, which could be significant, to return them to operating status.",

In November 2021, PT-FI completed agreements with MMC to implement the expansion of PT Smelting’s capacity by 30% to 1.3 million metric tons of concentrate per year, which is expected to be completed by the end of 2023. PT-FI is funding the cost of the expansion with a loan that is expected to convert to equity, increasing its ownership in PT Smelting from 39.5% to a majority ownership once the expansion is complete. Refer to Note 3 for further discussion. Prior to 2023, PT-FI’s contract with PT Smelting provided for PT-FI to supply 100% of the copper concentrate requirements (subject to a minimum or maximum treatment charge rate) necessary for PT Smelting to produce 205,000 metric tons of copper annually on a priority basis. PT-FI could also then sell copper concentrate to PT Smelting at market rates for quantities in excess of 205,000 metric tons of copper annually. Beginning in 2023, PT-FI's commercial arrangement with PT Smelting converted to a tolling arrangement. Under the arrangement, PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sale to third parties. This arrangement is not expected to result in a significant change in PT-FI's economics but will impact the timing of PT-FI’s sales during 2023. We estimate that approximately 90 million pounds of copper and 120 thousand ounces of gold from PT-FI’s first-quarter 2023 production will remain in inventory until final sale later in 2023. PT Smelting received a one-year extension of its anode slimes export license, which currently expires November 3, 2023. Refer to Item 1A. “Risk Factors” for further discussion of risks associated with PT Smelting’s export of anode slimes. PT Smelting’s anode production from its smelter totaled 316,700 metric tons of copper in 2022, 280,400 metric tons in 2021 and 276,900 metric tons in 2020. Copper cathode production from its refinery totaled 268,400 metric tons of copper in 2022, 256,900 metric tons in 2021 and 273,000 metric tons in 2020. PT Smelting’s maintenance turnarounds (which range from two weeks to a month to complete) typically are expected to occur approximately every two years, with short-term maintenance turnarounds in the interim. PT Smelting completed a 30-day maintenance turnaround during December 2020 and an 18-day maintenance turnaround in October 2022.

If we fail to recruit, retain, develop and advance qualified, inclusive and diverse personnel necessary for the efficient operation of our business, we could continue to face labor challenges, which may result in, but are not limited to, decreased profitability, further decreases to productivity and efficiency, ongoing safety performance challenges, and the further delay of current and potential development projects, any of which may have a material adverse effect on our performance.",
      "prior_body": "Our success is dependent on the contributions of our highly skilled and experienced workforce. Our business depends on our ability to recruit, retain, develop and advance a qualified, inclusive and diverse workforce at all levels. Our ability to recruit qualified personnel is affected by the available pool of workers with the training and skills necessary to fill the available positions, the impact on the labor supply because of general economic conditions and our ability to offer competitive compensation and benefit packages. Beginning in 2021 and during 2022, we experienced an increasingly competitive labor market and labor shortages at our North America operations. As a result of this labor shortage, we hired more contract workers in 2022, which increased our costs. If we fail to recruit, retain, develop and advance qualified, inclusive and diverse personnel necessary for the efficient operation of our business, this could result in decreased profitability, productivity and efficiency, safety performance challenges, and the delay of current and potential development projects, any of which may have a material adverse effect on our performance."

Maintaining the operational integrity and performance of our assets is crucial to protect our people, the environment and communities in which we operate. Our mines are very large in scale and, by their nature are subject to significant operational risks, some of which are outside of our control, and many of which are not covered fully, or in some cases even partially, by insurance. These operational risks, which could materially adversely affect our business, operating results and cash flows, include earthquakes, rainstorms, floods, wildfires and other natural disasters; environmental hazards, including discharge of metals, concentrates, pollutants or hazardous chemicals; surface or underground fires; equipment failures; accidents, including in connection with mining equipment, milling equipment or conveyor systems, transportation of chemicals, explosives or other materials and in the transportation of employees and other individuals to and from sites (including where these services are provided by third parties such as vehicle and aircraft transport); wall failures and rock slides in our open-pit mines, and structural collapses of our underground mines or tailings impoundments; underground water and ore management; lower than expected ore grades or recovery rates; and seismic activity resulting from unexpected or difficult geological formations or conditions (whether in mineral or gaseous form). For a discussion of risks specific to our tailings management, see the risk factors below relating to our management of waste rock and tailings, including our river transport system for tailings management in Indonesia. We are facing continued geotechnical challenges because of the older age of some of our open-pit mines and a trend toward mining deeper pits and more complex deposits. There can be no assurance that unanticipated geotechnical and hydrological conditions may not occur, nor whether these conditions may lead to events such as landslides and pit wall failures, or that such events will be detected in advance. Geotechnical instabilities can be difficult to predict and are often affected by risks and hazards outside of our control, such as seismic activity or severe weather, which may lead to floods, mudslides, pit-wall instability and possibly even slippage of material. For example, in late 2022, significant rainfall events impacted production at Morenci. Further, in early 2019, our El Abra 55 55 55 55 55 55 Table of Contents Table of Contents Table of Contents operation experienced heavy rainfall and electrical storms. As a result, our operating results for 2019 were impacted by a suspension of El Abra’s crushed leach stacking operations for approximately 35 days. We also experience mining induced seismic activity, including landslides, from time to time in the Grasberg minerals district in addition to severe weather. The mine site is in an active seismic area and has experienced earth tremors from time to time. In addition to the usual risks encountered in the mining industry, our Indonesia mining operations involve additional risks given their location in steep mountainous terrain in a remote area of Indonesia. These conditions have required us to overcome special engineering difficulties and develop extensive infrastructure facilities. The area also receives extreme rainfall, which has led to periodic floods and mudslides. In February 2023, PT-FI’s operations were temporarily disrupted because of significant rainfall and landslides, which restricted access to infrastructure near its milling operations. We cannot predict whether similar weather-related or seismic events will occur in the future or the extent to which any such event would affect these, or any of our other operations. Our business is dependent upon our workforce being able to safely perform their jobs. The occurrence of one or more of these events in connection with our exploration activities and development of and production from mining operations may result in the death of, or personal injury or illness to, our employees, other personnel or third parties, the loss of mining equipment, damage to or destruction of mineral properties or production facilities, significant repair costs, monetary losses, deferral or unanticipated fluctuations in production, extensive community disruption (including short- and long-term health and safety risks), loss of licenses, permits or necessary approvals to operate, loss of workforce confidence, loss of infrastructure and services, disruption to essential supplies or delivery of our products, environmental damage and potential legal liabilities, any of which may adversely affect our reputation, business, prospects, results of operations and financial position. Further, the impacts of any serious incidents that occur may also be amplified if we fail to respond timely or in an appropriate manner. Underground mining operations have unique risks that can be particularly dangerous, such as those associated with supporting the underground openings. In May 2013, the rock structure above the ceiling of an underground training facility at the Grasberg minerals district collapsed, which resulted in 28 fatalities and 10 injuries. While we have implemented preventative measures, we cannot guarantee that any incidents will not occur in the future. In addition, we could also be subject to operational risks at our smelters and refineries once PT-FI is fully dependent on its ability to smelt and refine domestically all its concentrates and slimes produced by its mining operations at the PT Smelting and the Indonesia smelter projects. Any delay, loss of access or limited availability and capacity related to these smelting and refinery facilities, including equipment failures, unanticipated or extended shutdowns, inability to sell certain by-products, lack of capacity to store certain by-products, severe weather, social or political unrest or any major public health crisis, any of which may not be recognized by the Indonesia government as a force majeure event, may significantly impact our ability to export and sell our copper and gold products, even if alternative refineries or smelters outside of Indonesia are available, and could adversely impact our revenues and results of operations. We maintain insurance at amounts we believe to be reasonable to cover some of these risks and hazards; however, our insurance may not sufficiently cover losses from certain of these risks and hazards. There can be no assurance that such insurance will continue to be available, maintained or available at economically feasible premiums, that the proceeds of such insurance will be paid in a timely manner or that we will be adequately compensated for losses actually incurred, if at all. We may elect to not purchase insurance for certain risks because of the high premium costs associated with insuring such risk or for various other reasons. We do not have coverage for certain environmental losses and other risks, including the legal liabilities associated with these risks. The lack of, or insufficiency of, insurance coverage could adversely affect our cash flows and overall profitability.",

Given the long-term nature of planning for mining investments, the Indonesia government is updating regulations that would enable PT-FI to apply for an extension of its IUPK beyond 2041. We cannot predict whether the regulations will be updated or that PT-FI will be successful in applying for the extension of its IUPK beyond 2041.",
      "prior_body": "On December 21, 2018, PT-FI was granted an IUPK to replace its former COW, enabling PT-FI to conduct operations in the Grasberg minerals district through 2041. Under the terms of the IUPK, PT-FI has been granted mining rights through 2031, with rights to extend its mining rights through 2041, subject to, among other things, PT-FI’s completion of construction of additional domestic smelting capacity totaling 2 million dry metric tons of 55 55 55 55 55 55 concentrate per year by the end of 2023 (an extension of which has been requested because of COVID-19 mitigation measures, subject to the approval of the Indonesia government), and fulfilling its defined fiscal obligations to the Indonesia government. Refer to Note 13 for a summary of the IUPK’s key fiscal terms. The expansion of PT Smelting is expected to be complete by the end of 2023 and the construction of the greenfield smelter is expected to be completed during 2024, which is subject to, among other things, no additional COVID-19 related disruptions. The IUPK also requires PT-FI to pay duties on concentrate exports of 2.5% now that development progress for additional smelting capacity in Indonesia has exceeded 30%, which may be eliminated upon receiving verification and approval from the Indonesia government that development progress for additional smelting capacity in Indonesia has exceeded 50%. Refer to Note 12 for further discussion of the administrative fine paid by PT-FI to the Indonesia government for failing to achieve physical development progress on the greenfield smelter. The current capital cost estimate for the greenfield smelter and related precious metal refinery approximates $3 billion (excluding capitalized interest, owner’s costs and commissioning). Capital expenditures for the Indonesia smelter projects are being funded with proceeds from PT-FI's senior notes and its available revolving credit facility. PT-FI’s ability to raise and service any additional sources of capital, if needed, would be a function of macroeconomic conditions, and future market prices as well as PT-FI’s operational performance, cash flows and debt position, among other factors. Additional financing may not be available if and when needed or, if available, the terms of such financing may not be favorable to PT-FI. See the risk factor below regarding increasing scrutiny and evolving expectations from stakeholders, including creditors, with respect to our ESG practices, performance and disclosures. Our proven and probable mineral reserves in Indonesia reflect estimates of minerals that can be recovered through the end of 2041, and PT-FI’s current long-term mine plan and planned operations are based on the assumption that PT-FI will abide by the terms and conditions of the IUPK and will be granted the 10-year extension from 2031 through 2041. As a result, PT-FI will not mine all of these mineral reserves during the initial term of the IUPK. Prior to the end of 2031, we expect to mine 46% of aggregate proven and probable recoverable mineral reserves at December 31, 2022, representing approximately half of our net equity share of recoverable copper and gold reserves. If PT-FI does not complete the construction of additional domestic smelting capacity totaling 2 million metric tons of concentrate per year by the end of 2023 (an extension of which has been requested because of COVID-19 mitigation measures, subject to the approval of the Indonesia government), or fulfill its defined fiscal obligations to the Indonesia government as set forth in the IUPK, the IUPK may not be extended from 2031 through 2041, and PT-FI would be unable to mine all of its proven and probable mineral reserves in the Grasberg minerals district, which would adversely affect our business, results of operations and financial position. PT-FI and the Indonesia government have begun preliminary discussions regarding the extension of PT-FI's IUPK beyond 2041. We cannot predict whether PT-FI will be successful in the extension of its IUPK beyond 2041."

      "current_body": "Indonesia Indonesia has long faced separatist movements and civil and religious strife in a number of provinces. Several separatist groups have sought increased political independence for the province of Central Papua, where our Grasberg minerals district is located. In Central Papua, there have been attacks on civilians by separatists and conflicts between separatists and the Indonesia military and police. In addition, illegal artisanal miners have clashed with police who have attempted to move them away from our facilities. Social, economic and political instability in Central Papua could materially adversely affect us if it results in damage to our property or interruption of our Indonesia operations. Shooting incidents have occurred within the PT-FI project area, including along the road leading to our mining and milling operations, which in some instances have involved fatalities or injuries to our employees, contractor employees, government security personnel and civilians.

During the first half of 2020, there were several shooting incidents, including an incident near a PT-FI office building where one employee was killed and two others injured. In January 2021, a helicopter contracted by PT-FI was fired upon and struck by a single gunshot in an area adjacent to the project area. In 2023, outside of the PT-FI operational area but within the province of Central Papua, there were at least 40 incidents of separatist violence, resulting in 20 fatalities. Separatist security incidents, including shootings, attacks on civil infrastructure and arson, continue to occur in Central Papua and other areas near the PT-FI project area. PT-FI actively monitors security conditions and the occurrence of incidents both within the project area and regionally. The safety of our workforce is a critical concern, and PT-FI continues to work with the Indonesia government to enhance security and address security-related issues within the PT-FI project area and in nearby areas. Although we have implemented measures and safeguards consistent with both international standards and our own internal standards relating to the use of force and respect for human rights, the implementation of these measures and safeguards does not guarantee that personnel, national police or other security forces will uphold these standards in every instance. We continue to limit the use of the road leading to PT-FI’s mining and milling operations to secured convoys, including transport of personnel by armored vehicles in designated areas. Once the PMR is commissioned, we expect to be exposed to security risks relating to loss and theft of refined precious metals. Any such loss or theft could lead to financial loss or a failure to satisfy our customers, which could have an adverse impact on our reputation and business. We cannot predict whether additional incidents will occur that could result in loss of life, or disruption or suspension of PT-FI’s operations. If other disruptive incidents occur, they could adversely affect our results of operations and financial condition. South America South America countries have historically experienced uneven periods of economic growth, as well as recession, periods of high inflation and general economic and political instability. In Peru, political uncertainty has created instability in the regulatory environment. Beginning in December 2022 and continuing in 2023, heightened tensions, protests and social unrest emerged in Peru following a change in the country’s political leadership, which temporarily resulted in delays in the transport of supplies, products and people at our Cerro Verde mine. During first-quarter 2023, Cerro Verde also operated at reduced rates from time-to-time until it resumed normal operations in March 2023. Other mining operations in the region temporarily halted mining activities as a result of the civil unrest. While demonstrations and road blockages subsided in 2023, the potential for civil unrest and disruption of commerce and supply chains continues. Other operations in the region have encountered significant issues with trespassers, illegal artisanal miners and civil demonstrations that impact their current operations, expansion projects, logistical supply and product transport. Such protests have occasionally been accompanied by acts of violence and property damage and continue intermittently in the region. In Chile, despite the overwhelming electoral approval of a proposal to rewrite the constitution in a 2020 referendum, the product of the constitutional assembly was rejected by a majority of voters in 2022 and 2023. Uncertainty in the resolution of constitutional reform may contribute to incidents of social unrest. We cannot predict whether similar or more significant incidents of civil unrest or political instability will occur in the future in Peru or Chile. Although such civil unrest has not significantly impacted our results, similar events in the future could cause our South America operations to be materially impacted, in which case, we may not be able to meet our production and sales targets.",

South America countries have historically experienced uneven periods of economic growth, as well as recession, periods of high inflation and general economic and political instability. Since 2019, both Peru and Chile have experienced significant civil unrest unrelated to our operations. For example, in 2022, an unaffiliated copper producer in southern Peru repeatedly curtailed or suspended operations because of repeated and sustained community protests on the government-designated concentrate transport route along public roads, which have constrained such producer and at times other local producers from shipping their products. Such protests are ongoing. Other operations in the region have encountered significant issues with trespassers, illegal artisanal miners, and civil demonstrations that impact their current operations, expansion projects, logistical supply and product transport. Such protests have occasionally been accompanied by acts of violence and property damage, and continue intermittently in the region. Although such civil unrest has not significantly impacted our results, similar events in the future could cause our South America operations to be materially impacted, in which case, we may not be able to meet our production and sales targets. Political uncertainty has created potential instability in the regulatory environment in Peru. In December 2022, Peru’s congress impeached President Castillo, who was subsequently taken into custody by Peruvian authorities, and Vice President Boluarte was sworn in as president. Following these events, there have been widespread and sometimes violent political protests, including attacks on civil infrastructure and businesses, which have resulted in delays in the transport of supplies, products and people at our Cerro Verde mine. Other mining operations in the region have temporarily halted mining activities as a result of the civil unrest. A national state of emergency has been declared, and military forces deployed to augment national police, which have resulted in civilian and police fatalities. Although there has been a limited impact on Cerro Verde’s operations, the situation in Peru remains uncertain, and a prolonged disruption of logistics and supply chains could impact future operations. In Chile, despite the overwhelming electoral approval of a proposal to rewrite the constitution in a 2020 referendum, the product of the constitutional assembly was rejected by over 60% of voters in 2022. While support for constitutional reform remains strong, uncertainty in the resolution of constitutional reform may contribute to incidents of social unrest. We cannot predict whether similar or more significant incidents of civil unrest or political instability will occur in the future in Peru or Chile. 60 60 60 60 60 60"

      "current_body": "Mining operations on the scale of our Indonesia operations involve significant environmental risks and challenges. Our primary challenge is to dispose of the large volume of tailings. In 2023, PT-FI produced approximately 69 million metric tons of tailings. Our tailings management plan, which has been approved by the Indonesia government, uses an unnavigable river in the highlands to transport the tailings from the mill to an engineered tailings management area in the lowlands. Levees have been constructed along both sides of the lowlands tailings management area to act as containment structures to laterally contain the footprint of the tailings deposition within the approved tailings management area. Another major environmental challenge at PT-FI is managing overburden, which is rock that was required to be moved aside in the open pit mining process to reach the ore in the Grasberg open pit. In the presence of air, water and naturally occurring bacteria, some overburden can generate acid rock drainage, or acidic water containing dissolved metals that, if not properly managed, can adversely affect the environment. In addition, the Grasberg overburden stockpiles experienced erosion over time, caused by the large amounts of rainfall, with the eroded stockpile material eventually entering into the lowlands tailings management area. This eroded overburden affects the volume as well as the physical and chemical characteristics of the sediment material deposited in the lowlands tailings management area, which can, if not properly managed, result in environmental impacts. The underlying overburden erosion and run-off are being managed and controlled through an extensive re-sloping and water management project, and PT-FI has not experienced similar erosion issues since 2018. However, PT-FI continues to monitor for potential impacts resulting from past erosion or the possibility of erosion recurrence. PT-FI’s current tailings deposition management plan and environmental monitoring program consider the presence of this overburden in the lowlands tailings management area. PT-FI has expanded the scope of its ongoing management and monitoring, which assesses possible impacts to the environment and human health from overburden erosion and tailings. During 2023, PT-FI continued its routine assessments of surface waters, groundwaters, sediments and soils, dust and terrestrial and aquatic tissues. As part of the expanded scope, in 2022 57 57 57 57 57 57 Table of Contents Table of Contents Table of Contents and 2023, PT-FI also assisted the Mimika local health authority with an extensive regency-wide community health survey, which provided further data on a broad range of community health issues. The local health authority then prioritized those items having the greatest expected impact on public health. There were no impacts attributable to PT-FI’s operations (inclusive of tailings and overburden erosion) that were determined to be a priority focus following the results of the local health authority’s assessment. In response to the health survey results, PT-FI and the local health authority have agreed to collaborate on public health challenges. Future testing and community health surveys may be used to assess the effectiveness of the local health authority’s priority programs and educational efforts. In the past, the Indonesia government, stakeholders and other third parties have raised questions with respect to our tailings and overburden management plans, including a suggestion that we implement a tailings pipeline and dam rather than the river transport system for tailings management. Our Indonesia mining operations are remotely located in steep mountainous terrain and in an active seismic area, which also experiences extreme weather events; such that, the pipeline infrastructure required to convey the volume of material is not feasible. Based on our own studies and others conducted by third parties, we believe that our controlled riverine transport system is the best site-specific option for tailings management at the Grasberg minerals district. Overtopping or failure of any of the PT-FI tailings containment structures (levees or protection structures) induced by extreme weather events such as floods, a major seismic event or naturally-occurring weak ground under the structures, are potential risks. The potential impacts from any such occurrence could vary significantly depending upon the specific location of the failure. Unanticipated structural failure of these structures in certain areas in the future could result in flooding of the nearby communities and related loss of lives and/or severe personal, property and environmental damages. Under certain conditions, a failure may necessitate evacuation or relocation of communities or other emergency action, financial assistance to the communities impacted, and remediation costs to repair and compensate for the social, cultural and economic impacts associated with such failure. In addition, in the southern (estuary) portion of the approved tailings management area, mathematical modeling of certain sediment transport scenarios indicate tailings have the potential to be deposited outside of the approved lateral levees in adjacent mangroves. PT-FI has proposed additional extensions to the existing levees to the Indonesia regulators and is further evaluating the potential benefits and impacts. Indonesia regulators have further proposed a different strategy involving efforts to increase sediment retention through various methods as well as increase beneficial use of tailings. If the additional retention efforts are not successful, or if the permitting for these proposed protection structures is not reconsidered, any such depositional impacts outside of our existing approved footprint could impact the environment and communities. Refer to Items 1. and 2. “Business and Properties” for further discussion of our environmental obligations in Indonesia. Managing these environmental challenges at our Indonesia operations could result in reputational harm and increased costs that could be significant. There can be no assurance that future environmental changes affecting the mining industry in Indonesia will not be introduced or unexpectedly altered or repealed, or that new interpretations of existing Indonesia environmental laws and regulations will not be issued, which could have a significant impact on PT-FI.",

During 2022, PT-FI continued routine assessment of surface waters, groundwaters, sediments and soils, dust and terrestrial and aquatic tissues. Furthermore, PT-FI has been assisting local health authorities with an extensive regency-wide community health survey, which is providing further data on community health issues, including any potential impacts from operations.

In addition, in the southern portion of the approved tailings management area, tailings have the potential to create depositional impacts outside of the approved boundary unless the protection structures (as proposed by PT-FI) are extended. An extension of these protection structures is planned and is currently awaiting permitting, which continues to progress. If the permitting for these protection structures is not received in a timely manner, or not received at all, there is a risk that the tailings in the lower portion of the tailings management area could create depositional impacts outside of our approved footprint and potentially impact the environment and communities.

Partially because of the Grasberg minerals district’s significance to Indonesia’s economy, the environmentally sensitive area where it is located, and the number of local people employed, our Indonesia operations have been the subject of political debates and criticism in the Indonesia press, 53 53 53 53 53 53 Table of Contents Table of Contents Table of Contents and have been the target of protests and occasional violence. Improper management of our working relationship with the Indonesia government, MIND ID or the local population could lead to a disruption of operations and/or impact our reputation in Indonesia and in the region where we operate, which could adversely affect our business. The mining industry is subject to extensive regulation within Indonesia, and there have been major developments in laws and regulations applicable to mining concession holders, some of which have conflicted with PT-FI’s contractual rights and may conflict with PT-FI’s contractual rights in the future. The enactment of Law No. 4 of 2009 on Coal and Mineral Mining on January 12, 2009 (the Mining Law) replaced the previous regulatory framework which allowed concession holders, including PT-FI, to conduct mining activities in Indonesia under a contract of work system. Notwithstanding provisions in PT-FI’s former Contract of Work (COW) prohibiting it from doing so, the Indonesia government sought to modify PT-FI’s former COW to address provisions contained in the Mining Law and implementing regulations adopted thereunder, some of which were not required under or conflicted with PT-FI’s former COW. In addition, in early 2017, the Indonesia government issued new regulations to address exports of unrefined metals, including copper concentrates and anode slimes, and other matters related to the mining sector. On December 21, 2018, PT-FI was granted an IUPK to replace its former COW, enabling PT-FI to conduct operations in the Grasberg minerals district through 2041, subject to certain requirements. Refer to Note 13 for a summary of the IUPK’s key fiscal terms and requirement to develop additional smelting and refining capacity. Since 2019, the Indonesia government has enacted various laws and regulations related to downstream processing of various products. Refer to “Operations – Indonesia Mining” in MD&A and Notes 12, 13 and 14 for a discussion of Indonesia regulatory matters, including those related to export licenses, export duties, export proceeds, smelter assurance bonds and smelter development progress, including assessing administrative fines. In 2023, PT-FI was granted export licenses for copper concentrates and anode slimes, both of which are valid through May 2024. PT-FI has requested approvals to continue exports of copper concentrates and anode slimes beyond May 2024 and until the Manyar smelter and precious metals refinery (PMR) in Indonesia (collectively, the Indonesia smelter projects) are fully commissioned and reach designed operating conditions. We cannot predict if PT-FI will be able to obtain approval timely or at all to continue exports beyond May 2024, including of sufficient volumes of copper concentrates and anode slimes. If any limitations on exports or additional financial impacts resulting from Indonesia regulations were to be assessed prior to PT-FI’s Indonesia smelter projects becoming operational later in 2024, PT-FI would be required to reduce production levels or be subject to additional costs, which could adversely impact our revenues and operations. Further, PT-FI continues to discuss the applicability of the revised regulation for export duties with the Indonesia government because of inconsistencies with its IUPK. If PT-FI is unable to successfully dispute the export duties, it may be unable to recover the assessed duties and would be required to continue paying such duties until the Manyar smelter construction is completed and operational. There can be no assurance that future regulatory changes affecting the mining industry in Indonesia will not be introduced or unexpectedly repealed, or that new interpretations of existing laws and regulations will not be issued, any of which may conflict with PT-FI’s contractual rights, which could adversely affect our business, financial condition and results of operations. Beginning in 2022, the Indonesia government divided the Indonesia portion of the island of New Guinea from two provinces into a total of six provinces, which has resulted in public protest and civil unrest. For further discussion of violence, civil and religious strife, and activism affecting our operations in Indonesia, see the related risk factor below. Further, we cannot predict the impact of splitting provinces on local and regional regulations, permits and other governmental administrative functions, which could have an adverse impact on our business. In 2024, Indonesia is holding national legislative elections, including the presidential election. Political considerations leading up to and resulting from these elections could affect, among other things, national and local policies pertaining to foreign investment, permitting and export restrictions, which could adversely affect our Indonesia mining operations. 54 54 54 54 54 54 Table of Contents Table of Contents Table of Contents",
      "prior_body": "Maintaining a good working relationship with the Indonesia government, PT Indonesia Asahan Aluminium (Persero) (PT Inalum, also known as MIND ID), an Indonesia state-owned enterprise and shareholder in PT-FI and the local population, is important because of the significance of our Indonesia operations to our business, and because our mining operations there are among Indonesia’s most significant business enterprises. Partially because of the Grasberg minerals district’s significance to Indonesia’s economy, the environmentally sensitive area where it is located, and the number of people employed, our Indonesia operations have been the subject of political debates and criticism in the Indonesia press, and have been the target of protests and occasional violence. Improper management of our working relationship with the Indonesia government, MIND ID or the local population could lead to a disruption of operations and/or impact our reputation in Indonesia and in the region where we operate, which could adversely affect our business. The mining industry is subject to extensive regulation within Indonesia, and there have been major developments in laws and regulations applicable to mining concession holders, some of which have conflicted with PT-FI’s contractual rights in the past. In particular, the enactment of Law No. 4 of 2009 on Coal and Mineral Mining on January 12, 2009 (the Mining Law) replaced the previous regulatory framework which allowed concession holders, 54 54 54 54 54 54 including PT-FI, to conduct mining activities in Indonesia under a contract of work system. Notwithstanding provisions in PT-FI’s former Contract of Work (COW) prohibiting it from doing so, the Indonesia government sought to modify PT-FI’s former COW to address provisions contained in the Mining Law and implementing regulations adopted thereunder, some of which were not required under or conflicted with PT-FI’s former COW. In early 2017, the Indonesia government issued new regulations to address exports of unrefined metals, including copper concentrate and anode slimes, and other matters related to the mining sector. Copper concentrate sales to PT Smelting (PT-FI’s 39.5% owned copper smelter and refinery located in Gresik, Indonesia) totaled over 10% of our consolidated revenues for each of the years ended December 31, 2022, 2021 and 2020. PT-FI’s export license for copper concentrate is valid for one-year periods, subject to review by the Indonesia government every six months, depending on greenfield smelter construction progress. PT-FI’s current export license remains valid through March 19, 2023. Refer to Note 12 for further discussion of the administrative fine paid by PT-FI to the Indonesia government in March 2022 for failing to achieve physical development progress on the greenfield smelter. The 2017 regulations also permit the export of anode slimes, which is necessary for PT Smelting to continue operating. PT Smelting’s export license for anode slimes expires on November 3, 2023. As discussed in Note 3, beginning in January 2023, PT-FI’s commercial arrangement with PT Smelting converted to a tolling arrangement, under which PT-FI pays PT Smelting a tolling fee to smelt and refine its concentrate and will retain title to all products for sales to third parties. Notwithstanding PT-FI’s rights to export copper concentrate through 2023 under its IUPK (subject to force majeure considerations), its current copper concentrate export license and PT Smelting’s current anode slimes export license, PT-FI may not be able to obtain administrative approval for such exports if the Indonesia government bans exports of copper concentrate and anode slimes prior to completion of the greenfield smelter and precious metals refinery (PMR). Recent press reports have indicated that the Indonesia government is considering a ban of copper concentrate exports effective in June 2023 under regulations that were issued in 2020 and 2021. In addition, PT Smelting exports may also be restricted (contrary to the expiration date of PT Smelting’s current export license noted above). If such limitations on exports were to be instituted prior to PT-FI’s greenfield smelter and PMR becoming operational (currently expected in 2024), PT-FI would be required to reduce production levels or be subject to additional costs. Further, even if the Indonesia government does not ban exports of copper concentrate or anode slimes, we cannot predict when and if PT-FI’s copper concentrate export license and PT Smelting’s anode slimes export license may be renewed. PT-FI’s sales of copper concentrate and anode slimes could be interrupted if the export licenses are not timely renewed or if PT-FI or PT Smelting is unable to operate because of other operational or financial constraints, which would adversely impact our revenues and operations. There can be no assurance that future regulatory changes affecting the mining industry in Indonesia will not be introduced or unexpectedly repealed, or that new interpretations of existing laws and regulations will not be issued, which could adversely affect our business, financial condition and results of operations. In 2022, the Indonesia government divided the Indonesia portion of the island of New Guinea from two provinces into a total of six provinces, which has resulted in public protest and civil unrest. For further discussion of violence, civil and religious strife, and activism affecting our operations in Indonesia, see the related risk factor below. Further, we cannot predict the impact of splitting provinces on local and regional regulations, permits and other governmental administrative functions, which could have an adverse impact on our business. In 2024, Indonesia will hold national legislative elections. The presidential election will be held in February 2024. Political considerations leading up to these elections could affect, among other things, the country’s policies pertaining to foreign investment, permitting and export restrictions, which could adversely affect our Indonesia mining operations."

As our dependence on information systems, including those of our third-party service providers and vendors, grows, we have become more vulnerable to an increasing threat of continually evolving cybersecurity risks. In recent years, 60 60 60 60 60 60 Table of Contents Table of Contents Table of Contents cybersecurity events have increased in frequency and magnitude and the methods used to gain unauthorized access change frequently, making it increasingly difficult for us to prevent cybersecurity incidents or detect and remediate incidents in a timely and effective manner. Attacks have included and may include, but are not limited to, installation of malicious software, phishing, ransomware, social engineering tactics and credential attacks, insider threats, denial of service attacks, unauthorized access to data and other advanced and sophisticated cybersecurity breaches and threats, including those that increasingly target critical operational technologies and process control networks and those that are increasingly using artificial intelligence (AI) and quantum computing. Such attacks may be perpetrated by a variety of bad actors, some of which may reside in jurisdictions where law enforcement measures to address such attacks are ineffective. We have experienced targeted and non-targeted cybersecurity events in the past and may experience them in the future. In August 2023, we determined that we were subject to a cybersecurity incident that affected certain of our information systems. We performed an investigation of the incident and its associated impact and incurred costs to remediate, which were not material. We cannot guarantee that events of a similar nature, with potentially greater exposure, will not occur in the future. Cybersecurity threats could subject us to manipulation or improper use of our systems and networks, production downtimes, loss of sales, communication interruption or other disruptions and delays to our operations or to the transportation of products or infrastructure utilized by our operations, unauthorized release of proprietary, commercially sensitive, confidential or otherwise protected information, a misappropriation or loss of funds, the corruption of data, significant health and safety consequences, physical destruction of assets, environmental damage, loss of intellectual property, fines, penalties, litigation, regulatory or governmental investigation, liability under or termination of our contracts with third parties, damage to our reputation or financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, results of operations and financial condition, and which in addition could adversely impact the effectiveness of our internal control over financial reporting. We do not maintain cyber risk insurance, and the lack of insurance coverage could adversely affect our cash flows and overall profitability in the event of a material cybersecurity incident. While the August 2023 cybersecurity incident and other cybersecurity events have not had a material impact on us, we can provide no assurance that we will not experience any such impact or additional interruptions to our operations in the future. Given the unpredictability of the timing and the evolving nature and scope of information and operational technology system disruptions, the various procedures and controls we use to monitor and protect against cybersecurity threats and to mitigate potential risks arising from such threats have not been effective in some instances and may not be sufficient in preventing future cybersecurity incidents. Further, as cybersecurity threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate vulnerabilities to cybersecurity threats. We could also be adversely affected by system or network disruptions if new or upgraded information or operational technology systems are defective, not installed properly or not properly integrated into our operations. System modification failures could have a material adverse effect on our business, financial position and results of operations and could, if not successfully implemented, adversely impact the effectiveness of our internal control over financial reporting. Further, we increasingly depend on our information technology infrastructure for electronic communications among our operations, personnel, customers and suppliers around the world, including as a result of remote working and flexible working arrangements. These information technology systems, some of which are managed by third parties that we do not control, may be susceptible to damage, disruptions or shutdowns because of failures during the process of upgrading or replacing software, databases or components thereof, cutover activities in our restructuring and simplification initiatives, power outages, hardware failures, telecommunication failures, human errors, catastrophic events or other problems. Refer to Item 1C. “Cybersecurity” for further information on our cybersecurity governance, risk management and strategy. Artificial Intelligence and Other New Technologies Information and operational technology systems continue to evolve and, in order to remain competitive, we must implement new technologies in a timely, cost-effective and efficient manner. For example, we may develop and apply AI in decision support systems, material characterization, equipment reliability, mineral extraction and remote/autonomous operation. These applications may become important in our operations over time. We also are advancing a series of initiatives to incorporate new applications, technologies and data analytics to our leaching 61 61 61 61 61 61 Table of Contents Table of Contents Table of Contents processes. For additional information on our leaching innovation initiatives, see MD&A. Our failure to successfully implement new technologies, including AI, may adversely affect our competitiveness and, consequently, our results of operations. In addition, we may utilize AI and other new technologies in software provided by third parties to enhance our capabilities in producing copper, improving business processes and responding to threats to our technology platforms. The use of AI may increase our exposure to cybersecurity risks and additional risks relating to the protection of data, including increased exposure of confidential or otherwise protected information to unauthorized recipients, which could result in liability under or termination of our contracts with third parties, misuse of our intellectual property or other unintended consequences.",

      "current_body": "In addition to mineral reserves, our properties contain mineral resources that we believe could be brought into production should market conditions warrant. However, permitting and significant capital expenditures may be required before mining of these resources could commence at these properties. A mineral resource is a concentration or occurrence of material of economic interest in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. Such a deposit cannot qualify as recoverable proven and probable mineral reserves until engineering, legal and economic feasibility are confirmed based upon a comprehensive evaluation of development and operating costs, grades, recoveries and other material factors. Mineral resources include measured, indicated and inferred mineral classifications. •A measured mineral resource is a resource for which the quantity and grade are estimated from detailed, closely spaced sampling, and geologic characterization that defines the size, shape, depth and mineral content to a high degree of confidence. •An indicated mineral resource is a resource for which quantity and grade are estimated from information similar to that used for measured mineral resources where the samples are farther apart, and the geological characterization is adequate. •An inferred mineral resource is a resource for which quantity and grade are estimated from information similar to that used for measured and indicated mineral resources, but with limited geological evidence and sampling. Inferred mineral resource grade and mineralization continuity have a lower degree of confidence. Our estimates of mineral resources have been prepared in accordance with the disclosure requirements of Subpart 1300 of SEC Regulation S-K. No assurance can be given that the estimated mineral resources not included in mineral reserves will become proven and probable mineral reserves.

      "prior_body": "In addition to mineral reserves, our properties contain mineral resources that we believe could be brought into production should market conditions warrant. However, permitting and significant capital expenditures may be required before mining of these resources could commence at these properties. A mineral resource is a concentration or occurrence of material of economic interest in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. Such a deposit cannot qualify as recoverable proven and probable mineral reserves until engineering, legal and economic feasibility are confirmed based upon a comprehensive evaluation of development and operating costs, grades, recoveries and other material factors. Mineral resources include measured, indicated and inferred mineral classifications. •A measured mineral resource is a resource for which the quantity and grade are estimated from detailed, closely spaced sampling, and geologic characterization that defines the size, shape, depth and mineral content to a high degree of confidence. •An indicated mineral resource is a resource for which quantity and grade are estimated from information similar to that used for measured mineral resources where the samples are farther apart, and the geological characterization is adequate. •An inferred mineral resource is a resource for which quantity and grade are estimated from information similar to that used for measured and indicated mineral resources, but with limited geological evidence and sampling. Inferred mineral resource grade and mineralization continuity have a lower degree of confidence. Our estimates of mineral resources have been prepared in accordance with the disclosure requirements of Subpart 1300 of SEC Regulation S-K. No assurance can be given that the estimated mineral resources not included in mineral reserves will become proven and probable mineral reserves.

These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors other than the candidates nominated by the Board. Refer to Exhibit 4.1 for further discussion of our anti-takeover provisions. Further, our By-Laws provide to the fullest extent permitted by law that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, the U.S. District Court for the District of Delaware) will be the sole and exclusive forum for any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim that is based upon a violation of a duty by any of our current or former directors, officers, employees or stockholders in such capacity, (iii) action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or to which the Delaware General Corporation Law confers jurisdiction upon the Court of Chancery of the State of Delaware, (iv) action asserting a claim governed by the internal affairs doctrine, or (v) action asserting an “internal corporate claim” as that term is defined in Section 115 of the Delaware General Corporation Law. The exclusive forum provision may increase costs to bring a claim, discourage claims or limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us or our directors, officers and other employees. Alternatively, if a court were to find the exclusive forum provision contained in our By-Laws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions. The exclusive forum provision in our By-Laws will not preclude or contract the scope of exclusive federal or concurrent jurisdiction for actions brought under the federal securities laws including the Securities Exchange Act of 1934, as amended, or the Securities Act of 1933, as amended, or the respective rules and regulations promulgated thereunder. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit large stockholders from consummating a merger with, or acquisition of, us. These provisions may deter an acquisition of us that might otherwise be attractive to our stockholders."

As a result, our ability to service our indebtedness, pay dividends, and repurchase shares and debt is dependent on the generation of cash flows by our subsidiaries and their ability to make such cash available to us, by dividend, loan, debt repayment or otherwise. Our subsidiaries do not have any obligation to make funds available to us to service our indebtedness, pay dividends, or repurchase shares and debt. Dividends from subsidiaries that are not wholly owned are shared with other equity owners. Cash at our international operations is also typically subject to foreign withholding taxes upon repatriation into the U.S. In addition, our subsidiaries may not be able to, or be permitted to, make distributions to us or repay loans to us, to enable us to service our indebtedness, pay dividends, or repurchase shares and debt. Each of our subsidiaries is a distinct legal entity and, under certain circumstances, legal restrictions, as well as the financial condition and operating requirements of our subsidiaries, may limit our ability to obtain cash from our subsidiaries. Certain of our subsidiaries are parties to credit agreements that restrict their ability to make distributions or loan repayments to us if such subsidiary is in default under such agreements, or to transfer substantially all of the assets of such subsidiary without the consent of the lenders. Our rights to participate in any distribution of our subsidiaries’ assets upon their liquidation, reorganization or insolvency would generally be subject to the prior claims of the subsidiaries’ creditors, including any trade creditors. As more fully described in Note 10, during 2021, our Board of Directors (Board) adopted a performance-based payout framework, which currently includes base and variable dividends and a share repurchase program. Our ability to continue to pay dividends (base or variable) and the timing and amount of any share repurchases is at the discretion of our Board and management, respectively, and is subject to a number of factors, including not exceeding our net debt target, capital availability, our financial results, cash requirements, global economic conditions, changes in laws, contractual restrictions and other factors deemed relevant by our Board or management, as applicable. Repurchases of our common stock under our repurchase program are discretionary up to the Board-approved limit, and our share repurchase program may be modified, increased, suspended or terminated at any time at the Board’s discretion. Our dividend payments and share repurchases may change, and there can be no assurance that we will continue to declare dividends or repurchase shares at all or in any particular amounts. A reduction or suspension in our dividend payments or share repurchases could have a negative effect on the price of our common stock. 69 69 69 69 69 69 Table of Contents Table of Contents Table of Contents"

      "current_body": "We are required by U.S. federal and state laws and regulations to provide financial assurance sufficient to allow a third party to implement approved closure and reclamation plans for our mining properties if we are unable to do so. As of December 31, 2023, our financial assurance obligations totaled $1.8 billion for closure and reclamation costs of U.S. mining sites. Refer to Note 12 for additional information regarding our financial assurance obligations and Items 1. and 2. “Business and Properties” for a discussion of certain of such U.S. federal and state laws and regulations applicable to us. A substantial portion of our financial assurance obligations are satisfied by guarantees by us and certain of our subsidiaries. Our ability to continue to provide guarantees depends on state and other regulatory requirements, our financial performance and our financial condition. Other forms of assurance, such as letters of credit and surety bonds, are costly to provide and, depending on our financial condition and market conditions, may be difficult or impossible to obtain. Failure to provide or maintain the required financial assurance could result in the closure of the affected properties. Plans and provisions for mine closure, reclamation and remediation may change over time as a result of changes in stakeholder and other third-party expectations, legislation, standards, and technical understanding and techniques, which may cause our actual costs of closure, reclamation and remediation to be higher than estimated for asset retirement obligations (AROs) and environmental obligations and could materially affect our financial position or results of operations. For example, our implementation of the Global Industry Standard for Tailings Management (the Tailings Standard) (refer to Items 1. and 2. “Business and Properties” for further discussion) has required changes and could require additional changes to our closure and reclamation plans or modifications to previously completed reclamation actions, although it is uncertain if these changes would result in material capital or operating cost increases. In addition, climate change could lead to changes in the physical risks posed to our operations, which could result in changes in our closure and reclamation plans to address such risks. Any modifications to our closure and reclamation plans that may be required to address physical climate risks may increase our financial assurance obligations and may materially increase the actual costs associated with implementing closure and reclamation at any or all of our active or inactive mine sites or smelter sites.

      "current_body": "Our estimates of mineral reserves and mineral resources have been prepared in accordance with the disclosure requirements of Subpart 1300 of U.S. Securities and Exchange Commission (SEC) Regulation S-K. There are numerous uncertainties inherent in mineral estimates. Such estimates are, to a large extent, based on assumed long-term prices for the commodities we produce, primarily copper, gold and molybdenum, and interpretations of geologic data obtained from drill holes and other exploration techniques, which may not necessarily be indicative of future results. Our mineral estimates are based on the latest available geological and geotechnical studies. We conduct ongoing studies of our ore bodies to optimize economic values and to manage risk. We revise our mine plans and estimates of recoverable proven and probable mineral reserves as required in accordance with the latest available studies. Geological assumptions about our mineral resources that are valid at the time of estimation may change significantly when new information becomes available. Estimates of mineral reserves, or the cost at which we anticipate the mineral reserves will be recovered, are based on assumptions, such as metal prices and other economic inputs. Changes to such assumptions may require revisions to mineral reserve estimates which could affect our asset carrying values and may also negatively impact our future financial condition and results. Until mineral reserves are actually mined and processed, the quantity of ore and grades must be considered as an estimate only. In addition, if the market prices for the commodities we produce decline from assumed levels, if production costs increase or recovery rates decrease, or if applicable laws and regulations are adversely changed, there can be no assurance that the indicated level of recovery will be realized or that mineral reserves can be mined or processed profitably. If we determine that certain of our estimated recoverable proven and probable mineral reserves have become uneconomic, this may ultimately lead to a reduction in our aggregate reported mineral reserves, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, the term “mineral resources” does not indicate recoverable proven and probable mineral reserves as defined by the SEC. Estimates of mineral resources are subject to further exploration and evaluation of development and operating costs, grades, recoveries and other material factors, and, therefore, are subject to considerable uncertainty. Mineral resources do not meet the threshold for mineral reserve modifying factors, such as engineering, legal and/or economic feasibility, that would allow for the conversion to mineral reserves. Accordingly, there can be no assurance that the estimated mineral resources not included in mineral reserves will become recoverable proven and probable mineral reserves."

We participated in developing these Voluntary Principles with other major natural resource companies and international human rights organizations and they are incorporated into our Human Rights Policy. The Voluntary Principles provide guidelines for our security programs, including interaction with host-government security personnel, private security contractors and our internal security employees. Our Human Rights Policy reflects our commitment to implementing the United Nations Guiding Principles on Business and Human Rights. We conduct site-level human rights impact assessments (HRIAs) at our global operations, which help us to embed human rights considerations into our business practices. We completed HRIAs at our PT-FI Grasberg operations in 2023, Arizona operations in 2022, El Abra in 2021, New Mexico operations in 2018 and Cerro Verde in 2017. In 2023, we initiated a second HRIA at Cerro Verde, which is expected to be completed later in 2024, and we initiated the planning phase for HRIAs at the Manyar smelter and our Colorado operations. We continue to participate in a multi-industry human rights working group to gain insight from peer companies and experts in the field to learn how best practices are evolving. We believe that our social and economic development programs are responsive to the issues raised by the local communities near our areas of operation and help us maintain good relations with the surrounding communities and avoid disruptions of mining operations. As part of our ongoing commitment to our community stakeholders, we have made and expect to continue making investments in certain social programs, including in-kind support and administration, across our global operations from time to time.

Nevertheless, social and political instability in the areas of our operations may adversely impact our mining operations. Refer to Item 1A. “Risk Factors” for further discussion. South America. Cerro Verde has provided a variety of community support projects over the years. Following engagements with regional and local governments, civic leaders and development agencies, in 2006, Cerro Verde committed to support the costs for a new potable water treatment plant to serve Arequipa. In addition, an agreement was reached with the Peru government for development of a water storage network that was financed by Cerro Verde and a distribution network that was financed by the Cerro Verde Civil Association. Cerro Verde constructed a wastewater treatment plant for the city of Arequipa, which was completed in 2015. The wastewater treatment plant supplements existing water supplies to support Cerro Verde’s concentrator expansion and also improves the local water quality, enhances agriculture products grown in the area and reduces the risk of waterborne illnesses. In addition to these projects, Cerro Verde annually makes significant community development investments in the Arequipa region. Security Matters. Consistent with our operating permits in Peru and our commitment to protect our employees and property, we have taken steps to provide a safe and secure working environment.

PT-FI provides funding and technical assistance to support various community development programs in areas such as health, education, economic development and local infrastructure. In 1996, PT-FI established a social investment fund with the aim of contributing to social and economic development in the Mimika Regency. Prior to 2019, the fund was mainly managed by the Amungme and Kamoro Community Development Organization, a community-led institution. In 2019, a new foundation, the Amungme and Kamoro Community Empowerment Foundation (Yayasan Pemberdayaan Masyarakat Amungme dan Kamoro, or YPMAK), was established, and in 2020, PT-FI appointed YPMAK to assist in distributing a significant portion of PT-FI’s funding to support the development and empowerment of the local Indigenous Papuan people. YPMAK is governed by a Board of Governors consisting of seven representatives, including four from PT-FI. In addition, since 2001, PT-FI has voluntarily established and contributed to land rights trust funds administered by Amungme and Kamoro representatives that focus on socioeconomic initiatives, human rights and environmental issues. PT-FI is committed to the continued funding of YPMAK programs and the land rights trust funds, as well as for other local-community development initiatives through 2041 and has made and expects to continue making annual investments in public health, education, and local economic development.

Safford is located in Graham County, Arizona, 8 miles north of the town of Safford and 170 miles east of Phoenix. The site is accessible by a paved county road off U.S. Highway 70. The Safford mine includes three copper deposits that have oxide mineralization overlaying primary copper sulfide mineralization. The predominant oxide copper minerals are chrysocolla and copper-bearing iron oxides with the predominant copper sulfide material being chalcopyrite. The only Safford deposit currently being mined is Lone Star, which began leaching operations in the second half of 2020 and production from oxide ores averaged 265 million pounds of copper per year over the past three years. We continue to advance plans to increase volumes to achieve 300 million pounds of copper per year from oxide ores, which reflects a continuing expansion of the initial design capacity of 200 million pounds of copper per year. Positive drilling conducted in recent years indicates opportunities to expand production to include sulfide ores in the future. We are completing metallurgical testing and mine development planning and expect to commence pre-feasibility studies during 2024 for a potential significant expansion. Safford is a mine-for-leach operation that produces copper cathode. The operation consists of three open pits, of which only Lone Star is currently being mined, feeding a crushing facility with a design capacity of 103,500 metric tons of ore per day. The crushed ore is delivered to a leach pad by a series of overland and portable conveyors. Leach solutions feed a SX/EW facility with a capacity of 305 million pounds of copper per year.

These laws and regulations are subject to change and to changing interpretation by governmental agencies and other bodies vested with broad supervisory authority. As a mining company, compliance with environmental, health and safety laws and regulations is an integral and costly part of our business. In addition, we must obtain regulatory permits and approvals to start, continue and expand operations. 64 64 64 64 64 64 Table of Contents Table of Contents Table of Contents Certain federal and similar state laws and regulations may expose us to joint and several liability for environmental damages caused by our operations, or by previous owners or operators of properties we acquired or are currently operating or at sites where we previously sent materials for processing, recycling or disposal. As discussed in more detail in the risk factor below relating to costs incurred for remediating environmental conditions on our properties that are no longer in operation, we have substantial obligations for environmental remediation on properties previously owned or operated by Freeport Minerals Corporation (FMC) and certain of its affiliates. Noncompliance with these laws and regulations could result in material penalties or other liabilities. In addition, compliance with these laws may from time to time result in delays in or changes to our development or expansion plans. Compliance with these laws and regulations imposes substantial costs, which we expect will continue to increase over time because of increased regulatory oversight, adoption of increasingly stringent environmental standards, and other factors. New or revised environmental regulatory requirements are frequently proposed, many of which have resulted and may in the future result in substantially increased costs for our business, including those regarding financial obligations. Regulations have been considered at various governmental levels to increase financial responsibility requirements for mine closure and reclamation. Federal regulations obligating additional hazardous air pollutant controls at our Miami, Arizona smelter are also under consideration. Adoption of such environmental regulations or more stringent application of existing regulations may materially increase our costs, threaten certain operating activities and constrain our expansion opportunities. In addition, there can be no assurance that restrictions relating to conservation will not have an adverse impact on expansion of our operations or not result in delays in project development, or constraints on exploration or operations in impacted areas. We have incurred and expect to incur environmental capital expenditures and other environmental costs (including our joint venture partners’ shares) to comply with applicable environmental laws and regulations that affect our operations. The timing and amounts of estimated payments could change as a result of changes in regulatory requirements, changes in scope and costs of reclamation activities, the settlement of environmental matters and the rate at which actual spending occurs on continuing matters. We are also subject to extensive regulation of worker health and safety. Our mines are inspected on a regular basis by government regulators who may issue citations and orders when they believe a violation has occurred under applicable mining regulations. If inspections result in an alleged violation, we may be subject to fines and penalties and, in instances of alleged significant violations, our mining operations or industrial facilities could be subject to temporary or extended closures. Many other governmental bodies regulate other aspects of our operations, and our failure to comply with these legal requirements can result in substantial penalties. In addition, new laws and regulations, including executive orders, or changes to or new interpretations of existing laws and regulations by courts or regulatory authorities occur regularly, but are difficult to predict. Any such variations could negatively impact the mining sector, including our business, substantially increase costs to achieve compliance or otherwise have a material adverse effect on our cash flows, results of operations and financial condition.

(19.58%) and other stockholders whose Cerro Verde shares are publicly traded on the Lima Stock Exchange (5.86%). Cerro Verde is an open-pit copper and molybdenum mining complex that has been in operation since 1976. Cerro Verde is located 20 miles southwest of Arequipa, Peru. Prior to being acquired in 1994 by a predecessor of Phelps Dodge, the mine was previously operated by the Peru government. The property is located at latitude 16.53 degrees south and longitude 71.58 degrees west using the WGS 84 coordinate system. The site is accessible by paved highways. Cerro Verde’s copper cathode and concentrate production that is not sold locally is transported approximately 70 miles by truck and by rail to the Port of Matarani for shipment to international markets. Molybdenum concentrate is transported by truck to either the Ports of Callao or Matarani for shipment. 18 18 18 18 18 18 Table of Contents Table of Contents Table of Contents The Cerro Verde mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper minerals are brochantite, chrysocolla, malachite and copper “pitch.” Chalcocite and covellite are the most important secondary copper sulfide minerals. Chalcopyrite and molybdenite are the dominant primary sulfides. Cerro Verde’s operation includes 2 concentrating facilities with an annual average permitted milling capacity of 409,500 metric tons of ore per day (and the ability to annually treat up to 5% more for a total of 430,000 metric tons of ore per day). As a result of several efficiency initiatives implemented over the past several years, in 2023, Cerro Verde’s 2 concentrators were able to achieve a combined average milling rate of 417,400 metric tons of ore per day in 2023. Cerro Verde also operates SX/EW leaching facilities, which have a production capacity of approximately 200 million pounds of copper per year. In 2023, Cerro Verde began to dismantle its crushed leach facility (which had a capacity of 39,000 metric tons of ore per day) as a result of pit expansion but continues to utilize its 100,000-metric-ton-per-day ROM leach system. The available fleet consists of fifty-four 300-metric-ton haul trucks (1 of which is currently on standby), ninety-three 250-metric-ton haul trucks (10 of which are currently on standby) and 7 leased 380-metric-ton haul trucks loaded by 13 electric shovels with bucket sizes ranging from 33 to 57 cubic meters. This fleet is capable of moving an average of approximately 1,000,000 metric tons of material per day. Cerro Verde’s net PP&E and mine development costs at December 31, 2023, totaled $5.9 billion. Cerro Verde’s production totaled 1.0 billion pounds of copper and 22 million pounds of molybdenum in 2023, 1.0 billion pounds of copper and 23 million pounds of molybdenum in 2022, and 0.9 billion pounds of copper and 21 million pounds of molybdenum in 2021. Cerro Verde is located in a desert environment with rainfall averaging less than two inches per year and is in an active seismic zone. The highest bench elevation is 2,768 meters above sea level and the ultimate pit bottom is expected to be 1,538 meters above sea level. The Peru general mining law and Cerro Verde’s mining stability agreement grant the surface rights of mining concessions located on government land. Government land obtained after 1997 must be leased or purchased. Cerro Verde has a mining concession covering approximately 175,000 acres, including 62,000 acres of surface rights and access to 14,600 acres granted through an easement from the Peru National Assets Office, plus 151 acres of owned property, and 1,151 acres of rights-of-way outside the mining concession area leased from both government agencies and private parties. Cerro Verde currently receives electrical power, including hydro-generated power, under long-term contracts with ElectroPeru and Engie Energia Peru S.A. During 2023, Cerro Verde entered into a new power purchase agreement that is expected to transition its electric power to fully renewable energy sources in 2026. Water for our Cerro Verde processing operations comes from renewable sources through a series of storage reservoirs on the Río Chili watershed that collect water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant operated by Cerro Verde. We believe the Cerro Verde operation has sufficient water sources to support current operations, but we are closely monitoring ongoing El Niño weather patterns.

El Abra is an open-pit copper mining complex that has been in operation since 1996. El Abra is located 47 miles north of Calama in Chile’s El Loa province of the northern Chilean region of Antofagasta. The site is accessible by paved highways and by rail. The El Abra mine is a porphyry copper deposit that has sulfide and oxide mineralization. The predominant primary sulfide copper minerals are bornite and chalcopyrite. There is a minor amount of secondary sulfide mineralization as chalcocite. The oxide copper minerals are chrysocolla and pseudomalachite. There are lesser amounts of copper bearing clays and tenorite. The El Abra operation consists of a SX/EW facility with a capacity of 500 million pounds of copper cathode per year from a 125,000-metric-ton-per-day crushed leach circuit and a ROM leaching operation. The available fleet consists of twenty-three 242-metric-ton haul trucks loaded by 4 electric shovels with buckets ranging in size from 29 to 41 cubic meters, which are capable of moving 217,000 metric tons of material per day. El Abra’s net PP&E and mine development costs at December 31, 2023, totaled $0.8 billion. El Abra’s copper production totaled 217 million pounds in 2023, 202 million pounds in 2022 and 160 million pounds in 2021. Higher mining and stacking activities at El Abra over the past two years resulted in the increase in production compared to 2021. We have identified a large sulfide resource that would support a potential major mill project similar to the large-scale concentrator at Cerro Verde. Technical and economic studies continue to be evaluated to determine the optimal scope and timing for the sulfide project. Capital cost requirements are being updated to reflect current market conditions. We are evaluating water infrastructure alternatives to provide options to extend existing operations and support a future expansion, while continuing to monitor Chile’s regulatory and fiscal matters, as well as trends in capital costs for similar projects. In parallel, as part of the permitting process for the potential expansion, we are planning for a potential submission of an environmental impact statement during 2025, subject to ongoing stakeholder engagement and economic evaluations. El Abra is located in a desert environment with rainfall averaging less than one inch per year and is in an active seismic zone. The highest bench elevation is 4,225 meters above sea level and the ultimate pit bottom is expected to be 3,385 meters above sea level. El Abra controls a total of approximately 183,900 acres of mining claims covering the ore deposit, stockpiles, process plant, and water wellfield and pipeline. In addition, El Abra has land surface rights for the road between the processing plant and the mine, the water wellfield, power transmission lines and for the water pipeline from the Salar de Ascotán aquifer. El Abra currently receives electrical power under a long-term contract with Engie Energia Chile S.A. Water for our El Abra processing operations currently comes from the continued pumping of groundwater from the Salar de Ascotán aquifer pursuant to regulatory approval. We believe El Abra has sufficient water sources to support current operations, although we are evaluating options for water infrastructure alternatives to provide options to extend existing operations and support a future expansion.

PT-FI is a limited liability company organized under the laws of the Republic of Indonesia. On December 21, 2018, we completed the transaction with the Indonesia government regarding PT-FI’s long-term mining rights and share ownership (the 2018 Transaction). Following the 2018 Transaction, we have a 48.76% share ownership in PT-FI and the remaining 51.24% share ownership is collectively held by PT Mineral Industri Indonesia (MIND ID), an Indonesia state-owned enterprise, and PT Indonesia Papua Metal Dan Mineral (formerly known as PT Indocopper Investama), which is expected to be owned by MIND ID and the provincial/regional government in Central Papua, Indonesia. Refer to Note 3 for further discussion of the economics related to the 2018 Transaction. IUPK. Concurrent with closing the 2018 Transaction, the Indonesia government granted PT-FI a special mining license (IUPK) to replace its former Contract of Work, enabling PT-FI to conduct operations in the Grasberg minerals district through 2041. Under the terms of the IUPK, PT-FI has been granted an extension of mining rights through 2031, with rights to extend mining rights through 2041, subject to PT-FI completing the construction of additional domestic smelting and refining capacity in Indonesia and fulfilling its defined fiscal obligations to the Indonesia government. The IUPK, and related documentation, contains legal and fiscal terms and is legally enforceable through 2041. In addition, we, as a foreign investor, have rights to resolve investment disputes with the Indonesia government through international arbitration. Given the long-term nature of planning for mining investments, the Indonesia government is updating regulations that would enable PT-FI to apply for an extension of its IUPK beyond 2041. An extension would enable continuity of large-scale operations and provide growth options through additional resource development opportunities in the Grasberg minerals district. Refer to Item 1A. “Risk Factors” and Note 13 for discussion of PT-FI’s IUPK and risks associated with our Indonesia mining operations. Indonesia Smelting and Refining Capacity. In connection with PT-FI’s 2018 agreement with the Indonesia government to secure the extension of its long-term mining rights, PT-FI agreed to expand its domestic smelting and refining capacity. At the end of 2023, progress of the Manyar smelter and precious metals refinery (PMR) (collectively, the Indonesia smelter projects) was measured at over 90%. Refer to “Smelting Facilities and Other Mining Properties” below, Item 1A. “Risk Factors,” MD&A and Notes 12 and 13 for additional discussion of the Indonesia smelter projects. Grasberg Minerals District. PT-FI operates in the remote highlands of the Sudirman Mountain Range in the province of Central Papua, Indonesia, which is on the western half of the island of New Guinea. Since 1967, we and our predecessors have been the only operator of exploration and mining activities in the approximately 24,600-acre operating area. The operating area is accessible by coastal portsite facilities on the Arafura Sea and by the Timika 21 21 21 21 21 21 Table of Contents Table of Contents Table of Contents airport. The project site is located at latitude 4.08 degrees south and longitude 137.12 degrees east using the WGS 84 coordinate system. The project area includes a 70-mile main service road from portsite to the mill complex. PT-FI’s net PP&E and mine development costs at December 31, 2023, totaled $19.1 billion. Production from the Grasberg minerals district totaled 1.7 billion pounds of copper and 2.0 million ounces of gold in 2023, 1.6 billion pounds of copper and 1.8 million ounces of gold in 2022, and 1.3 billion pounds of copper and 1.4 million ounces of gold in 2021. Over a multi-year investment period, PT-FI has successfully commissioned three large-scale underground mines in the Grasberg minerals district (Grasberg Block Cave, Deep Mill Level Zone (DMLZ) and Big Gossan), which provided 100% of production volumes. Milling rates for ore from these underground mines averaged 198,300 metric tons of ore per day in 2023, an approximate 3% increase from 192,600 metric tons of ore per day in 2022, and an approximate 31% increase from 151,600 metric tons of ore per day in 2021. PT-FI set a number of annual operating records during 2023, including total underground ore mined (and milled) and volume of concentrate produced. Production from these underground mines is expected to continue through 2041 and an extension of PT-FI’s operating rights beyond 2041 would extend the lives of these mines. Refer to Item 1A. “Risk Factors” for discussion of risks associated with development projects and underground mines. In December 2023, PT-FI completed the installation of new milling facilities, which will enable PT-FI to further leverage the success of the underground mines and provide sustained large-scale production volumes. PT-FI is also advancing a mill recovery project with the installation of a new copper cleaner circuit that is expected to be completed in the second half of 2024 to provide incremental production of approximately 60 million pounds of copper and 40 thousand ounces of gold per year. Our principal source of power for our Indonesia operations is a coal-fired power plant that we built in 1998. Diesel generators supply peaking and backup electrical power generating capacity. In 2023, PT-FI commissioned a dual-fuel power plant to support increased power requirements and diversify its energy sources. PT-FI is advancing plans to transition its existing energy source from coal to liquefied natural gas, which is expected to meaningfully reduce PT-FI’s Scope 1 GHG emissions at the Grasberg minerals district. The project includes investments in a new gas-fired combined cycle facility. Capital expenditures for the new facilities, to be incurred over the next four years, approximate $1 billion representing an incremental cost of $0.4 billion compared to previously planned investments to refurbish the existing coal units. A combination of naturally occurring mountain streams and water derived from our underground operations provides water for our operations. Our Indonesia operations are in an active seismic zone and experience average annual rainfall of approximately 200 inches. Grasberg Block Cave Underground Mine The Grasberg Block Cave ore body is the same ore body historically mined from the surface in the Grasberg open pit. Undercutting, drawbell construction and ore extraction activities in the Grasberg Block Cave underground mine continue to track expectations. As of December 31, 2023, the Grasberg Block Cave underground mine had 425 open drawbells. Ore milled from the Grasberg Block Cave underground mine averaged 117,300 metric tons per day in 2023, 103,300 metric tons per day in 2022 and 70,600 metric tons per day in 2021. The Grasberg Block Cave fleet consists of approximately 870 pieces of mobile equipment. The primary mining equipment directly associated with production and development includes an available fleet of 98 LHD units and 22 haul trucks. Each production LHD unit typically carries approximately 11 metric tons of ore and transfers ore into the rail haulage system. The Grasberg Block Cave has a rail haulage system currently operating with 13 locomotives and 143 ore wagons that haul the ore to 3 gyratory crushers located underground via an automated rail system. Each ore wagon typically carries 35 metric tons. The crushed ore is conveyed to surface stockpiles for processing. 22 22 22 22 22 22 Table of Contents Table of Contents Table of Contents DMLZ Underground Mine The DMLZ ore body lies below the Deep Ore Zone (DOZ) underground mine at the 2,590-meter elevation and represents the downward continuation of mineralization in the Ertsberg East Skarn system and neighboring Ertsberg porphyry. Hydraulic fracturing operations have been effective in managing rock stresses and pre-conditioning the cave following mining-induced seismic activity experienced from time to time. As of December 31, 2023, the DMLZ underground mine had 132 open drawbells. Ore milled from the DMLZ underground mine averaged 75,900 metric tons per day in 2023, 76,300 metric tons per day in 2022 and 58,000 metric tons per day in 2021. The DMLZ fleet consists of 425 pieces of mobile equipment, which includes 60 LHD units and 33 haul trucks used in production and development activities. Each production LHD unit typically carries approximately 9 metric tons of ore and transfers ore into the truck haulage system. The haul trucks have a capacity of 55 to 60 metric tons and load ore from chutes fed by the LHDs and transfer it to one of two gyratory crushers. The crushed ore is conveyed to surface stockpiles for processing. Big Gossan Underground Mine The Big Gossan ore body lies underground and adjacent to the current mill site. It is a tabular, near vertical ore body with approximate dimensions of 1,200 meters along strike and 800 meters down dip with varying thicknesses from 20 meters to 120 meters. The mine utilizes a blasthole stoping method with delayed paste backfill. Stopes of varying sizes are mined and the ore dropped down passes to a truck haulage level. Trucks are chute loaded and transport the ore to a jaw crusher. The crushed ore is then hoisted vertically via a two-skip production shaft to a level where it is loaded onto a conveyor belt. The belt carries the ore to one of the main underground conveyors where the ore is transferred and conveyed to the surface stockpiles for processing. Ore milled from the Big Gossan underground mine averaged 7,900 metric tons per day in 2023, 7,600 metric tons per day in 2022 and 7,500 metric tons per day in 2021. The Big Gossan fleet consists of 79 pieces of mobile equipment, which include 10 LHD units and 8 haul trucks used in development and production activities. Kucing Liar Underground Mine Long-term mine development activities are ongoing for PT-FI’s Kucing Liar deposit in the Grasberg minerals district, which is expected to produce over 7 billion pounds of copper and 6 million ounces of gold between 2029 and the end of 2041. An extension of PT-FI’s operating rights beyond 2041 would extend the life of the project. Pre-production development activities commenced in 2022 and are expected to continue over an approximate 10-year timeframe. Capital investments are estimated to average approximately $400 million per year over this period. At full operating rates of approximately 90,000 metric tons of ore per day, annual production from Kucing Liar is expected to approximate 560 million pounds of copper and 520 thousand ounces of gold, providing PT-FI with sustained long-term, large-scale and low-cost production. Kucing Liar will benefit from substantial shared infrastructure and PT-FI’s experience and long-term success in block-cave mining. DOZ Underground Mine PT-FI began production from the DOZ ore body in 1989 and the ore body was depleted at the end of 2021. Grasberg Open Pit PT-FI began open-pit mining of the Grasberg ore body in 1990 and the final phase was mined during 2019. In aggregate, the Grasberg open pit produced over 27 billion pounds of copper and 46 million ounces of gold in the 30-year period from 1990 through 2019. Description of Indonesia Ore Bodies. Our Indonesia ore bodies are located within and around two main igneous intrusions, the Grasberg monzodiorite and the Ertsberg diorite. The host rocks of these ore bodies include both carbonate and clastic rocks that form the ridge crests and upper flanks of the Sudirman Range, and the igneous rocks of monzonitic to dioritic composition that intrude them. The igneous-hosted ore bodies (the Grasberg Block Cave and portions of the DMLZ) occur as vein stockworks and disseminations of copper sulfides, dominated by chalcopyrite and, to a lesser extent, bornite. The sedimentary-rock hosted ore bodies (portions of the DMLZ and Kucing Liar and all of the Big Gossan) occur as “magnetite-rich, calcium/magnesian skarn” replacements, whose 23 23 23 23 23 23 Table of Contents Table of Contents Table of Contents location and orientation are strongly influenced by major faults and by the chemistry of the carbonate rocks along the margins of the intrusions. The copper mineralization in these skarn deposits is dominated by chalcopyrite, but higher bornite concentrations are common. Moreover, gold occurs in significant concentrations in all of the district’s ore bodies, though rarely visible to the naked eye. These gold concentrations usually occur as inclusions within the copper sulfide minerals, though, in some deposits, these concentrations can also be strongly associated with pyrite. The following diagram indicates the relative elevations (in meters) of our reported Indonesia ore bodies. The following map, which encompasses an area of 42 square kilometers, indicates the relative positions and sizes of our reported Indonesia ore bodies and their locations. 24 24 24 24 24 24 Table of Contents Table of Contents Table of Contents"

Activities that occurred in the late 19th century and the 20th century prior to the advent of modern environmental laws were not subject to environmental regulation and were conducted before U.S. industrial companies fully understood the long-term effects of their operations on the surrounding environment. Companies like FMC are now legally responsible for remediating hazardous substances released into the environment on or from properties owned or operated by them as well as properties where they arranged for disposal of such substances, irrespective of when the release into the environment occurred or who caused it. That liability is often asserted on a joint and several basis with other prior and subsequent owners, operators and arrangers, meaning that each owner or operator of the property is, and each arranger may be, held fully responsible for the remediation, although in many cases some or all of the other responsible parties no longer exist, do not have 65 65 65 65 65 65 Table of Contents Table of Contents Table of Contents the financial ability to respond or cannot be found. As a result, because of our acquisition of FMC, many of the subsidiary companies we now own are potentially responsible for a wide variety of environmental remediation projects throughout the U.S., and we expect to spend substantial sums annually for many years to address those remediation issues. We are also subject to claims where the release of hazardous substances is alleged to have resulted in injury, destruction or loss of natural resources. At December 31, 2023, we had more than 80 active remediation projects in 22 U.S. states. In addition, FMC and certain affiliates and predecessor companies were parties to agreements relating to the transfer of businesses or properties that contained indemnification provisions relating to environmental matters, and from time to time these provisions become the source of claims against us. Our environmental obligation estimates are primarily based upon: •Our knowledge and beliefs about complex scientific and historical facts and circumstances that in many cases occurred many decades ago; •Our beliefs and assumptions regarding the nature, extent and duration of remediation activities that we will be required to undertake and the estimated costs of those remediation activities, which are subject to varying interpretations; and •Our beliefs regarding the requirements that are imposed on us by existing laws and regulations and, in some cases, the clarification of uncertain regulatory requirements that could materially affect our environmental obligation estimates. Significant adjustments to these estimates are likely to occur in the future as additional information becomes available. The actual environmental costs may exceed our current and future accruals for these costs, and any such changes could be material. In addition, remediation standards imposed by the U.S. Environmental Protection Agency and state environmental agencies have generally become more stringent over time and may become even more stringent in the future. Imposition of more stringent remediation standards, particularly for arsenic and lead in soils, poses a risk that additional remediation work could be required at our active remediation sites and at sites that we have already remediated to the satisfaction of the responsible governmental agencies, and may increase the risk of toxic tort litigation. Refer to Items 1. and 2. “Business and Properties” and Note 12 for further discussion of our environmental obligations."

A significant portion of our employees are represented by labor unions in a number of countries under various collective bargaining agreements with varying durations and expiration dates. Refer to Items 1. and 2. “Business and Properties” for additional information regarding labor matters, and expiration dates of such agreements. As of December 31, 2023, approximately 29% of our global labor force was covered by collective bargaining agreements and approximately 16% of our global labor force was covered by agreements that will or were scheduled to expire during 2024 or that had expired as of December 31, 2023, and continue to be negotiated. Labor agreements are negotiated on a periodic basis and may not be renewed on reasonably satisfactory terms to us or at all. If we do not successfully negotiate new collective bargaining agreements with our union workers, we may incur prolonged strikes and other work stoppages at our mining operations, which could adversely affect our financial condition and results of operations. Additionally, if we enter into a new labor agreement with any union that significantly increases our labor costs relative to our competitors, our ability to compete may be materially adversely affected. We have in the past and could in the future experience labor disruptions such as work stoppages, work slowdowns, union organizing campaigns, strikes, or lockouts that could adversely affect our operations. For example, in third-quarter 2020, we experienced a five-day labor-related work stoppage related to COVID-19 travel restrictions when a small group of workers at PT-FI staged protests and a blockade restricting access to the main road to the mining operations area. We reached an amicable resolution with the group of workers while upholding our COVID-19 safety protocols. There were no strikes or lockouts at any of our operations for the three years ended December 31, 2023. We cannot predict whether additional labor disruptions will occur. Significant reductions in productivity or protracted work stoppages at one or more of our operations could significantly reduce our production and sales volumes or disrupt operations, which could adversely affect our cash flows, results of operations and financial condition. 62 62 62 62 62 62 Table of Contents Table of Contents Table of Contents"

(15%) and SMM Morenci, Inc. (13%). Each partner takes in kind its share of Morenci’s production. Morenci is an open-pit copper mining complex that has been in continuous operation since 1939 and previously was mined through underground workings. In the 1880s, Phelps Dodge & Company (Phelps Dodge) first invested in the area, and through acquisition, consolidated all mining operations in the area by the 1920s. Phelps Dodge was acquired by FCX in 2007. Morenci is located in Greenlee County, Arizona, approximately 50 miles northeast of Safford on U.S. Highway 191. The property is located at latitude 33.07 degrees north and longitude 109.35 degrees west using the World Geodetic System (WGS) 84 coordinate system. The site is accessible by a paved highway and a railway spur. The Morenci mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, with chalcopyrite as the dominant primary copper sulfide. The Morenci operation consists of two concentrators with a milling design capacity of 132,000 metric tons of ore per day, which produce copper and molybdenum concentrate; a 72,500 metric ton-per-day, crushed-ore leach pad and stacking system; a low-grade run-of-mine (ROM) leaching system; four SX plants; and three EW tank houses that produce copper cathode. Total EW tank house capacity is approximately 900 million pounds of copper per year. Morenci’s available mining fleet consists of one hundred and forty-one 235-metric-ton haul trucks loaded by 13 electric shovels with bucket sizes ranging from 47 to 57 cubic meters. Morenci’s mining fleet is capable of moving an average of 785,000 metric tons of material per day. Our share of Morenci’s net property, plant, equipment (PP&E) and mine development costs at December 31, 2023, totaled $2.2 billion. Morenci’s production, including our joint venture partners’ share, totaled 0.8 billion pounds of copper and 3 million pounds of molybdenum in 2023, 0.9 billion pounds of copper and 4 million pounds of molybdenum in 2022, and 0.9 billion pounds of copper and 5 million pounds of molybdenum in 2021. Morenci is located in a desert environment with rainfall averaging 13 inches per year. The highest bench elevation is 1,900 meters above sea level and the ultimate pit bottom is expected to have an elevation of 760 meters above sea level. The Morenci operation encompasses approximately 61,700 acres, comprising 51,300 acres of fee lands and 10,400 acres of unpatented mining claims held on public mineral estate and numerous state or federal permits, easements and rights-of-way. The Morenci operation’s electrical power is supplied by our wholly owned subsidiary, The Morenci Water & Electric Company (MW&E). MW&E sources its generation services through our wholly owned subsidiary, Freeport-McMoRan Copper & Gold Energy Services LLC, through capacity rights at the Luna Energy Facility in Deming, New Mexico, and other power purchase agreements. Although we believe the Morenci operation has sufficient water sources to support current operations, we are a party to litigation that may impact our water right claims or rights to continued use of currently available water supplies, which could adversely affect our water supply for the Morenci operation.

Bagdad is located in Yavapai County in west-central Arizona, approximately 60 miles west of Prescott and 100 miles northwest of Phoenix. The property can be reached by U.S. Highway 93 to State Route 97 or Arizona Highway 96, which ends at the town of Bagdad. The closest railroad is at Hillside, Arizona, 24 miles southeast on Arizona Highway 96. The Bagdad mine is a porphyry copper deposit containing both sulfide and oxide mineralization. Chalcopyrite and molybdenite are the dominant primary sulfides and are the primary economic minerals in the mine. Chalcocite is the most common secondary copper sulfide mineral, and the predominant oxide copper minerals are chrysocolla, malachite and azurite. The Bagdad operation consists of a concentrator with a milling design capacity of 77,100 metric tons of ore per day that produces copper and molybdenum concentrate, a SX/EW plant that can produce approximately 9 million pounds per year of copper cathode from solution generated by low-grade stockpile leaching, and a pressure-leach plant to process molybdenum concentrate. The available mining fleet consists of thirty-five 235-metric-ton haul trucks loaded by 8 electric shovels with bucket sizes ranging from 30 to 48 cubic meters, which are capable of moving an average of 236,000 metric tons of material per day. In 2023, we announced a project to convert Bagdad’s fleet of haul trucks to become fully autonomous over the next three years. Bagdad’s net PP&E and mine development costs at December 31, 2023, totaled $0.8 billion. Bagdad’s production totaled 146 million pounds of copper and 10 million pounds of molybdenum in 2023, 165 million pounds of copper and 9 million pounds of molybdenum in 2022, and 184 million pounds of copper and 9 million pounds of molybdenum in 2021. We have a potential expansion project to more than double the concentrator capacity of the Bagdad operation. Bagdad’s reserve life currently exceeds 80 years and supports an expanded operation. In late 2023, we completed technical and economic studies, which indicated the opportunity to construct new concentrating facilities to expand capacity from 77,000 metric tons of ore per day to between 165,000 to 185,000 metric tons of ore per day. Estimated incremental project capital costs approximate $3.5 billion (excluding infrastructure that would be required in the long-range plans) and is expected to increase production by approximately 200-250 million pounds per year, which would more than double Bagdad’s current production. Expanded operations also are expected to provide improved efficiency and reduce unit net cash costs through economies of scale. Project economics indicate that the expansion would require an incentive copper price in the range of $3.50 to $4.00 per pound and would require approximately three to four years to complete. The decision to proceed and timing of the potential expansion will take into account overall copper market conditions, availability of labor and other factors, including progress on conversion of the existing haul truck fleet to autonomous and expanding housing alternatives to support long-range plans. In parallel, we are advancing activities for expanded tailings infrastructure projects required under long-range plans in order to advance the potential construction timeline. Refer to Item 1A. “Risk Factors” for further discussion. Bagdad is located in a desert environment with rainfall averaging 15 inches per year. The highest bench elevation is 1,250 meters above sea level and the ultimate pit bottom is expected to be 120 meters above sea level.

Investor advocacy groups, certain institutional investors, investment funds, creditors and other influential investors are increasingly focused on our ESG practices and in recent years have placed increasing importance on the ESG implications of their investments and lending decisions. Organizations that provide information to investors and financial institutions on ESG performance and related matters have developed quantitative and qualitative data collection processes and ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. In addition, many investors have created their own proprietary ratings that inform their investment and voting decisions. Unfavorable ratings or assessment of our ESG practices, including our compliance with certain voluntary disclosure standards and frameworks, may lead to negative investor sentiment toward us, which could have a negative impact on our stock price and our access to and cost of capital. Similarly, many financial institutions are increasingly incorporating ESG ratings or assessments into their credit risk assessments, and screen companies based on their ESG practices and performance when making lending decisions.

Proven and probable mineral reserves were determined from the application of relevant modifying factors to geological data to establish an operational, economically viable mine plan. The estimates are based on mapping, drilling, sampling, assaying and evaluation methods generally applied in the mining industry. Mineral reserves, as used in the mineral reserve data presented here, means the economically mineable part of a measured or indicated resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. Proven mineral reserves mean the economically mineable part of a measured mineral resource, from geological evidence revealed in outcrops, trenches, workings or drill holes with grades and/or quality estimates from detailed, closely spaced sampling, and geologic characterization that defines the size, shape, depth and mineral content to a high degree of confidence. Probable mineral reserves means the economically mineable part of an indicated mineral resource, for which quantity and grade are estimated from information similar to that used for measured mineral resources where the samples are farther apart, and the geological characterization is adequate. Probable mineral reserves can also include remaining portions of a measured mineral resource. The degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation. Our estimates of recoverable proven and probable mineral reserves are prepared by and are the responsibility of our employees. These estimates are reviewed and verified regularly by independent experts in mining, geology and reserve determination.

For additional information regarding recent macroeconomic and geopolitical factors, see risk factor 48 48 48 48 48 48 Table of Contents Table of Contents Table of Contents below regarding the price and availability of consumables and components we purchase and constraints on supply and logistics, and transportation services. There has been a history of significant volatility in the commodities markets, including the copper market. Fluctuations in commodities prices are caused by varied and complex factors beyond our control, including global supply and demand and inventory levels; global economic and political conditions (such as level of economic growth or recession and political or geopolitical conflicts); international regulatory, trade and/or tax policies, including national tariffs; commodities investment activity and speculation; interest rates; expectations regarding future inflation rates; the strength of the U.S. dollar compared to foreign currencies; the price and availability of substitute products; and changes in technology. Volatility in global economic growth, particularly in developing economies, has the potential to affect adversely future demand and prices for commodities. Geopolitical uncertainty and protectionism have the potential to inhibit international trade and negatively impact business confidence, which creates the risk of constraints on our ability to trade in certain markets and has the potential to increase price volatility. For additional information regarding the historical fluctuations of the prices of copper, gold and molybdenum, refer to “Markets” in MD&A. In addition to the factors discussed above, copper prices may be affected by demand from China, which is currently the largest consumer of refined copper in the world, including as a result of geopolitical uncertainty between the U.S. and China as well as uncertainties about China’s economy. The adoption and expansion of trade restrictions, or other governmental action related to tariffs or trade agreements or policies are difficult to predict and could adversely affect copper prices, demand for our products, our costs, our customers, our suppliers and the U.S. economy, which in turn could have a material adverse effect on our business, results of operations or financial condition. Copper prices also may be affected by the construction industry, the markets for automobiles and appliances, the global focus on a transition to new technologies for clean energy, advancement in communications and enhanced public health, and inadequate investment in and limited production from copper mining operations in South America, as well as demand from North America, Europe, and Asian countries other than China. Additional factors affecting gold prices may include purchases and sales of gold by governments and central banks, demand from China and India, two of the world’s largest consumers of gold, and global demand for jewelry containing gold. If market prices for the primary commodities we produce were to decline and remain low for a sustained period of time, we may have to revise our operating plans, including curtailing or modifying our mining and processing operations, as we have done in the past, and our cash flows, ability to return capital to shareholders and capital expenditure plans could be negatively affected. We may be unable to decrease our costs in an amount sufficient to offset reductions in revenues, in which case we may incur losses, and those losses may be material. Declines in prices of commodities we sell could also result in metals inventory adjustments and impairment charges for our long-lived assets."
