Colorado Reclamation Programs. FCX’s Colorado operations are regulated by the Colorado Mined Land Reclamation Act (Reclamation Act) and regulations promulgated thereunder. Under the Reclamation Act, mines are required to obtain approval of plans for reclamation of lands affected by mining operations to be performed during mining or upon cessation of mining operations. In March 2020, the Division of Reclamation, Mining, and Safety (DRMS) approved Henderson’s proposed update to its closure plan and closure cost estimate. As of December 31, 2021, FCX had accrued reclamation and closure costs of $153 million for its Colorado operations.   
In 2019, Colorado enacted legislation that requires proof of an end date for water treatment as a condition of permit authorizations for new mining operations and expansions beyond current permit authorizations. While this requirement does not apply to existing operations, it may lead to changes in long-term water management requirements at Climax and Henderson operations and AROs. In accordance with its permit from DRMS, Climax will submit an updated reclamation plan and cost estimate in 2024.  
Chile Reclamation and Closure Programs. 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. At December 31, 2021, FCX had accrued reclamation and closure costs of $82 million for its El Abra operation.   
Peru Reclamation and Closure Programs. Cerro Verde is subject to regulation under the Mine Closure Law administered by the Peru Ministry of Energy and Mines. 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, in 2017 Cerro Verde submitted its closure plan and cost estimate updated for the mine expansion, which was approved in February 2018. At December 31, 2021, FCX had accrued reclamation and closure costs of $141 million for its Cerro Verde operation.  
Indonesia Reclamation and Closure Programs. The ultimate amount of reclamation and closure costs to be incurred at PT-FI’s operations will be determined based on applicable laws and regulations and PT-FI’s assessment of appropriate remedial activities under the circumstances, after consultation with governmental authorities, affected local residents and other affected parties and cannot currently be projected with precision. Some reclamation costs will be incurred during mining activities, while the remaining reclamation costs will be incurred at the end of mining activities, which are currently estimated to continue through 2041. The construction time frame for reclamation of the West Wanagon overburden stockpile has been extended from 2025 to 2029 because safety constraints for working in steep and difficult terrain has reduced labor and equipment operating efficiencies. The time frame extension resulted in longer and escalating fixed costs, combined with additional anticipated volumes of stockpile material to be moved. As a result of the change in estimated costs, an ARO adjustment of $397 million was recorded in 2021, with $340 million charged to production and delivery costs, as it relates to the depleted Grasberg open pit. At December 31, 2021, FCX had accrued reclamation and closure costs of $1.1 billion for its PT-FI operations.  
Indonesia government regulations issued in 2010 require a company to provide a mine closure guarantee in the form of a time deposit placed in a state-owned bank in Indonesia. In December 2018, PT-FI, in conjunction with the issuance of its special mining license (IUPK), submitted a revised mine closure plan to Indonesia’s Department of Energy and Mineral Resources to reflect the extension of operations to 2041. At December 31, 2021, PT-FI had restricted time deposits totaling $113 million for mine closure and reclamation guarantees.  
Oil and Gas Properties. Substantially all of FM O&G’s oil and gas leases require that, upon termination of economic production, the working interest owners plug and abandon non-producing wellbores, remove equipment and facilities from leased acreage, and restore land in accordance with applicable local, state and federal laws. Following several sales transactions, FM O&G’s remaining operating areas primarily include offshore California and the Gulf of Mexico (GOM). As of December 31, 2021, FM O&G AROs cover 135 wells and approximately 100 platforms and other structures and it had accrued reclamation and closure costs of $337 million.
