Leases [Abstract]

Leases

Leases

The Company primarily enters into rental agreements for certain mining equipment that are for periods of 12 months or less, some of which include options to extend the leases. Leases that are for periods of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense on these agreements on a straight-line basis over the lease term. Additionally, the Company has certain finance leases for mining equipment that expire over various contractual periods. The leases have remaining lease terms of one to four years. These leases do not include an option to renew. Amortization expense for finance leases is included in depreciation and depletion expense.
