Asset Retirement Obligation Disclosure [Abstract]  
RECLAMATION RECLAMATION
Reclamation and mine closure costs are based principally on legal and regulatory requirements. Management estimates costs associated with reclamation of mining properties. On an ongoing basis, management evaluates its estimates and assumptions, and future expenditures could differ from current estimates. The estimated reclamation and mine closure costs were discounted using credit-adjusted, risk-free interest rates ranging from 6.7% to 9.6%. The asset retirement obligation increased in 2024 due to increased reclamation and mine closure costs associated with the continued build-out of the new leach pad at Rochester and the extended duration of water treatment as a result of new permitting requirements at Silvertip.
