Asset Retirement Obligation Disclosure [Abstract]  
RECLAMATION AND MINE CLOSURE
RECLAMATION
Reclamation and mine closure costs are based principally on legal and regulatory requirements. Management estimates costs associated with reclamation of mining properties as well as remediation costs for inactive properties. The Company uses assumptions about future costs, mineral prices, mineral processing recovery rates, production levels, capital costs and reclamation costs. On an ongoing basis, management evaluates its estimates and assumptions, and future expenditures could differ from current estimates.
Changes to the Company’s asset retirement obligations are as follows (in thousands):
