Non-current assets are tested for impairment or impairment reversals when events or changes in circumstances suggest that the carrying amount may not be recoverable. An impairment of a hoist at the Galena Complex was identified during the year ended December 31, 2025 where carrying value of $10.4 million was recognized as an impairment loss to plant and equipment. No other impairment or impairment reversal were identified for the year ended December 31, 2025 and 2024 for each of the Company’s cash-generating units, including non-producing properties and properties placed under care and maintenance.

Right-of-use lease assets consist of long-term commitments on mining equipment and office space leases.
