Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	CONTINGENCIES AND COMMITMENTS Environmental Refer to Note 10 of FCX’s 2024 Form 10-K for further discussion of FCX’s environmental obligations. Historical Smelter Sites. In July 2025, the New Jersey Department of Environmental Protection accepted FCX’s proposal for alternative remediation standards for sediment remediation in Arthur Kill, the water body adjacent to the former Carteret smelter site. During third-quarter 2025, FCX will work to develop remedial alternatives to establish a workplan and associated cost estimates, which are expected to result in an adjustment to the related environmental obligation. Litigation There were no significant updates to previously reported legal proceedings included in Note 10 of FCX’s 2024 Form 10-K, other than the matter discussed below. Asbestos and Talc Claims. The claimants in both the Imerys Talc America (Imerys) and Cyprus Mines Corporation (Cyprus Mines) bankruptcy cases previously approved a global settlement, which remains subject to bankruptcy court approvals in both cases. During second-quarter 2025, Imerys agreed to carve out a foreign subsidiary from the bankruptcy cases and the parties agreed to an amended plan to set up a separate sub-trust for foreign claimants. In accordance with the global settlement, as recently amended, Cyprus Amax Minerals Company (CAMC), an indirect wholly owned subsidiary of FCX and Cyprus Mines’ parent company, agreed to contribute $199 million in the aggregate over seven years to a proposed claimant trust, which includes $4 million for a sub-trust for potential foreign claimants that was added in second-quarter 2025. There can be no assurance that the amended plan will be approved by the bankruptcy court. In addition, in 2024, Cyprus Mines and Imerys entered into a settlement agreement with Johnson & Johnson (J&J), which became effective in February 2025. In accordance with the settlement agreement, (i) all indemnity claims against J&J were released, and Imerys and Cyprus Mines waived claims against insurers that could lead to the insurers asserting claims against J&J; and (ii) J&J agreed to pay $505 million to Imerys and Cyprus Mines (shared 50/50 between the two parties). In accordance with the settlement, Cyprus Mines received cash of $229 million during the first six months of 2025, with the remaining $24 million to be received by December 31, 2025. At June 30, 2025, FCX had a total litigation reserve of $452 million associated with the global settlement, including $253 million associated with the J&J settlement. Indonesia Regulatory Matters Refer to Notes 10, 11 and 12 of FCX’s 2024 Form 10-K for further discussion of Indonesia regulatory matters. Concentrate Exports. On March 17, 2025, the Indonesia government granted PTFI a copper concentrate export license through September 16, 2025, for 1.4 million metric tons of copper concentrate, and PTFI re-commenced exports of copper concentrate. Pursuant to current regulations, PTFI is required to pay a 7.5% export duty on copper concentrate exports. Export Proceeds. Effective March 1, 2025, the Indonesia government implemented a new regulation for export proceeds that requires 100% of export proceeds to be deposited in Indonesia banks for 12 months. The regulation allows the use of funds for ongoing business requirements, including dividends to shareholders, payment of taxes and other obligations to the Indonesia government, payment for materials or capital expenditures that are not available domestically and repayment of loans. Because PTFI has the ability to utilize its export proceeds to fund business requirements, these deposits are classified as cash and cash equivalents. Smelter Assurance. In March 2025, assurance bonds and funds required to be held in escrow to support commitment for smelter development were released following approval from the Indonesia government that PTFI’s smelter development obligation had been met. Administrative Fine. In March 2025, PTFI paid $59 million for an administrative fine that was previously assessed by the Indonesia government for delays in smelter development. The fine was fully accrued at year-end 2024. Long-Term Mining Rights. Pursuant to regulations issued during 2024, PTFI is eligible to apply for an extension of its mining rights beyond 2041, provided certain conditions are met, including ownership of integrated downstream facilities that have entered the operational stage; domestic ownership of at least 51% and agreement with a state-owned enterprise for an additional 10% ownership; and commitments for additional exploration and increases in refining capacity, each as approved by the Ministry of Energy and Mineral Resources. Application for extension may be submitted at any time up to one year prior to the expiration of PTFI’s special mining business license (IUPK). PTFI expects to apply for an extension during 2025, pending agreement with PT Mineral Industri Indonesia (MIND ID) on a purchase and sale agreement for the transfer of an additional 10% interest in PTFI to MIND ID beginning in 2041.
