Impairment of Long-lived Asset |
    The Company evaluates the carrying amounts of its long-lived assets for impairment whenever events and circumstances indicate the carrying value may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. Estimated undiscounted future net cash flows from each mineral property are calculated using estimated future production, three-year average metals prices, operating capital and costs, and reclamations costs. An impairment loss is recognized when the estimated discounted future cash flows expected to result from the use of an asset are less than the carrying amount of the asset. The Company’s estimates of future cash flows are subject to risks and uncertainties. It is reasonably possible that changes in estimates could occur which may affect the expected recoverability of the Company’s investments in mineral properties.
