Please see Note 11—Reclamation and Remediation in Item 8—Financial Statements and Supplementary Data for additional information.

In the first quarter of 2022, the gold regrind and dry stack tailings projects were completed and transferred out from construction-in-progress to mill facilities and infrastructure. We also added various machinery and equipment to the process plant and the underground mine (including filter press trays, mine equipment, low profile concrete mixer, etc.). The Company recorded depreciation and amortization expense for the years ended December 31, 2022 and 2021 of $28.0 million and $16.1 million, respectively.
