SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Significant Accounting Policies Please see Note 2 — Summary of Significant Accounting Policies contained in the 2024 10-K. 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 on stockpiles and 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. Ore on Leach Pads The heap leach process extracts silver and gold by placing ore on an impermeable pad and applying a diluted cyanide solution that dissolves a portion of the contained silver and gold, which are then recovered in metallurgical processes. The Company uses several integrated steps to scientifically measure the metal content of ore placed on the leach pads. As the ore body is drilled in preparation for the blasting process, samples are taken of the drill residue which are assayed to determine estimated quantities of contained metal. The Company then processes the ore through crushing facilities where the output is again weighed and sampled for assaying. A metallurgical reconciliation with the data collected from the mining operation is completed with appropriate adjustments made to previous estimates. The crushed ore is then transported to the leach pad for application of the leaching solution. As the leach solution is collected from the leach pads, it is continuously sampled for assaying. The quantity of leach solution is measured by flow meters throughout the leaching and precipitation process. After precipitation, the product is converted to doré at the Rochester mine and a form of gold electrolytic cathodic sludge at the Wharf mine, representing the final product produced by each mine. The inventory is stated at lower of cost or net realizable value, with cost being determined using a weighted average cost method. The historical cost of metal expected to be extracted within 12 months is classified as current and the historical cost of metals contained within the broken ore expected to be extracted beyond 12 months is classified as non-current. Ore on leach pads is valued based on actual production costs incurred to produce and place ore on the leach pad, less costs allocated to minerals recovered through the leach process. The estimate of both the ultimate recovery expected over time and the quantity of metal that may be extracted relative to the time the leach process occurs requires the use of estimates, which are inherently inaccurate due to the nature of the leaching process. The quantities of metal contained in the ore are based upon actual weights and assay analysis. The rate at which the leach process extracts gold and silver from the crushed ore is based upon laboratory testing and actual experience of more than 20 years of leach pad operations at the Rochester mine and 30 years of leach pad operations at the Wharf mine. The assumptions used by the Company to measure metal content during each stage of the inventory conversion process includes estimated recovery rates based on laboratory testing and assaying. The Company periodically reviews its estimates compared to actual experience and revises its estimates when appropriate. The ultimate recovery will not be known until leaching operations cease. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted for on a prospective basis. There are five reusable heap leach pads (load/offload) used at Wharf. Each pad goes through an approximate 24-month process of loading of ore, leaching and offloading which includes a neutralization and denitrification process. During the leaching cycle of each pad, revised estimated recoverable ounces for each of the pads may result in an upward or downward revision from time to time, which generally have not been significant. Updated recoverable ounce estimates are considered changes in estimate and were accounted for prospectively. As of June 30, 2025, the Company’s estimated recoverable ounces of gold and silver on the leach pads were 61,533 and 8.3 million, respectively. Goodwill Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in a business acquisition. Goodwill is allocated to reporting units and tested for impairment annually as of December 31 and when events or changes in circumstances indicate that the carrying value of a reporting unit exceeds its fair value. Each operating mine is considered a distinct reporting unit for purposes of goodwill impairment testing. The Company may elect to perform a qualitative assessment if it is more likely than not that the fair value exceeds the carrying value. If the Company determines that it is more likely than not that the fair value is less than the carrying value, a quantitative goodwill impairment test is performed to determine the fair value of the reporting unit. The fair value of a reporting unit is determined using either the income approach utilizing estimates of discounted future cash flows or the market approach utilizing recent transaction activity for comparable properties. These approaches are considered Level 3 fair value measurements. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Recently Adopted Accounting Standards In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The guidance is to be applied retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. We have adopted the new standard effective December 31, 2024 retrospectively for all periods presented. See Note 4 -- Segment Reporting for all periods presented with the new required disclosures. The new standard did not impact our Consolidated Financial Statements. Recently Issued Accounting Standards In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, which modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Although early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance, the Company believes that there is no material impact to the reader in early adoption. The Company plans to adopt this new guidance on our Consolidated Financial Statements and related disclosures on reporting year ending December 31, 2025. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures, which includes amendments to require the disclosure of certain specific costs and expenses that are included in a relevant expense caption on the face of the income statement. Specific costs and expenses that would be required to be disclosed include: purchases of inventory, employee compensation, depreciation and intangible asset amortization. Additionally, a qualitative description of other items is required, equal to the difference between the relevant expense caption and the separately disclosed specific costs. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, and are applied either prospectively or retrospectively at the option of the Company. We are evaluating the impact of the amendments on our Condensed Consolidated Financial Statements and related disclosures.
