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 2023 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. In the first quarter of 2024, the Company completed a review of the estimated recoverable ounces of gold and silver on its leach pads and determined that as a result of longer expected leach time and favorable recoveries relative to previous estimates, that the estimated recoverable gold and silver on the Rochester legacy (Stages 2, 3 and 4) leach pads supported an upward revision. An additional 6,000 ounces of gold and 900,000 ounces of silver were added to the legacy leach pads in the first quarter of 2024. 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 have not historically been significant. The updated recoverable ounce estimate is considered a change in estimate and was accounted for prospectively. As of June 30, 2024, the Company’s estimated recoverable ounces of gold and silver on the leach pads were 38,092 and 5.6 million, respectively. Recently Issued 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 are currently evaluating the potential impact of adopting this new guidance on our Condensed Consolidated Financial Statements and related disclosures. 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. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. We are currently evaluating the potential impact of adopting this new guidance on our Condensed Consolidated Financial Statements and related disclosures.
