Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES General Estimated losses from loss contingencies are accrued by a charge to income when information is available prior to the issuance of the financial statements that indicates it is probable that a liability could be incurred, and the amount of the loss can by reasonably estimated. Legal expenses associated with the loss contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss has been incurred. Environmental matters CC&V - Carlton Tunnel In December 2021, CC&V entered into a Settlement Agreement (“Settlement Agreement”) with the Water Quality Control Division of the Colorado Department of Public Health and Environment (the “Division”) with a mutual objective of resolving issues associated with the new discharge permits issued by the Division in January 2021 for the Carlton Tunnel. The Carlton Tunnel was a historic tunnel completed in 1941 with the purpose of draining the southern portion of the mining district, subsequently consolidated by CC&V. CC&V has held discharge permits for the Carlton Tunnel since 1983, primarily to focus on monitoring, with the monitoring data accumulated since the mid-1970s indicating consistency in the water quality discharged from the Carlton Tunnel over time. In 2006, legal proceedings and work with the regulator confirmed that the water flowing out of the Carlton Tunnel portal is akin to natural spring water and did not constitute mine drainage. However, this changed with the January 2021 permit updates, when the regulator imposed new water quality limits. The Settlement Agreement involves the evaluation of a reasonable and achievable timeline for treatment and permit compliance, acknowledging the lack of readily available technology, and the need to spend three years to study and select the technological solution, with three additional years to construct, bringing full permit compliance to the November 2027 timeframe. In 2022, CC&V studied various interim passive water treatment options, reported the study results to the Division. CC&V continues to study alternative long-term remediation plans for water discharged from the Carlton Tunnel, and is also working with regulators on site specific standards, a Discharger Specific Variance ("DSV") and other potential approaches to identify highest feasible alternative treatment in the context, based on limits such as area topography. CC&V formally submitted its proposal for the DSV and the matter will be presented to the Water Quality Control Commission in a June 2025 rulemaking hearing. Depending on the outcome of the hearing and other ongoing engagement with the Division, and the plans that may ultimately be agreed with the Division, a material adjustment to the liability may be required. Refer to Note 3 for further information on the acquisition of CC&V. Surety bonds The Company uses surety bonds to support certain environmental bonding obligations. As of March 31, 2025 and December 31, 2024, the Company had surety bonds totaling $492.4 million and $153.0 million outstanding, respectively. Other commitments and contingencies Following the Çöpler Incident, the Company has been named as a defendant in securities class actions in the United States and Canada and is subject to various risks and contingencies arising in the normal course of business. Based on the information currently available to the Company, no liability has been recorded for these lawsuits because the Company believes that any such liability is not probable and reasonably estimable at this time.
