Accounting Policies [Abstract] |
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The Company's Condensed Consolidated Financial Statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”). The preparation of the Company's Condensed Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to metal prices and mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of production amortization calculations, environmental, reclamation and closure obligations, estimates of recoverable silver and gold in leach pad inventories, estimates of fair value for certain reporting units and asset impairments, valuation allowances for deferred tax assets, and the fair value and accounting treatment of financial instruments, equity securities, asset acquisitions, the allocation of fair value to assets and liabilities assumed in connection with business combinations, and derivative instruments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will differ from the amounts estimated in these financial statements.
Recent Accounting Standards | Recently Issued Accounting Standards In March 2022, the FASB issued ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method” which is intended to make amendments to the fair value hedge accounting previously issued in ASU 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities”. The new standard is effective for reporting periods beginning after December 15, 2022. The standard introduced the portfolio layer method allowing multiple hedged layers of a single closed portfolio when applying fair value hedge accounting. The Company adopted the new derivatives and hedging standards effective January 1, 2023, which did not have a material effect on our financial position, results of operations or cash flows.
