Critical accounting policies and estimates used to prepare our financial statements are discussed with our audit committee as they are implemented on an annual basis. The were no significant changes in our critical accounting policies or estimates since December 31, 2023. For further details on the Company’s accounting policies and estimates, refer to the Company’s audited consolidated financial statements for the year ended December 31, 2024.

The preparation of these Consolidated Financial Statements requires management to make judgements, estimates and assumptions about the carrying amounts of assets and liabilities, disclosure of commitments and contingent liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. The determination of estimates requires the exercise of judgement based on various assumptions and other factors such as historical experience, current and expected economic conditions. Actual results could differ from these estimates. The significant judgements and estimates used in the preparation of these Consolidated Financial Statements that have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities and earnings within the next financial year include:

Acquisitions

Determination of whether a group of assets acquired and liabilities assumed constitute the acquisition of a business or an asset may require the Company to make certain judgments as to whether or not the assets acquired and liabilities assumed include the inputs, processes and outputs necessary to constitute a business.

With regard to the acquisition of Paycore, the Company determined that the transaction should be accounted for as an asset acquisition. In such cases, the acquirer identifies and recognizes the individual identifiable assets acquired and liabilities assumed. The cost of the group is allocated to the individual identifiable assets and liabilities on the basis of their relative fair values at the date of purchase. Such a transaction or event will not give rise to recording goodwill. The Paycore transaction was recorded based on the total consideration paid for the assets. Total consideration paid in excess of the acquired assets’ fair values was attributable to the acquired mineral interests.

Valuation of financial instruments and derivatives

The fair value of financial instruments that are not traded in an active market are determined using valuation techniques. The Company uses its judgment to select a variety of methods and makes significant assumptions that are mainly based on market conditions existing at initial recognition and at the end of each reporting period. Refer to Note 21 for further details on the methods and significant assumptions used.

Reclamation liabilities

Management assesses the reclamation liabilities on acquisition, on an annual basis or when new information becomes available. This assessment includes the estimation of the future rehabilitation costs required based on the existing laws and regulations in each jurisdiction the Company operates in, the timing of these expenditures, and the impact of changes in the discount rate. The actual future expenditures may differ from the amount currently provided if the estimates made are significantly different than actual results or if there are significant changes in environmental and / or regulatory requirements in the future.

Valuation of Inventories

Finished goods, work-in-process and stockpile and mineralized material on leach pad are valued at the lower of cost and net realizable value ("NRV"). The assumptions used on mineralized material on leach pad are the amount of gold stacked that is expected to be recovered from the leach pad. The assumptions used in the valuation of work-in-process inventories include estimates of gold in the mill circuits. The determination of NRV involves the use of estimates. The NRV of inventories is calculated as the estimated price at the time of eventual sale based on prevailing and forecast metals prices less estimated future costs to convert the inventories into saleable form and associated selling costs. The NRV of inventories is assessed at the end of each reporting period. Changes in estimates of NRV may result in a write-down of inventories.

Impairment of long-lived assets

The Company assesses the carrying value of its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts of such assets may not be recoverable. Events or circumstances that could indicate that the carrying value of an asset may not be recoverable include, but are not limited to, significant adverse changes in the business climate including changes in future metal prices, significant changes to the extent or manner in which the asset is being used or its physical condition including significant decreases in production or mineral reserves, and significant decreases in the market price of the assets.

In evaluating long-lived assets for recoverability, estimates of undiscounted future cash flows of the Company's mines are used. Estimates of future cash flows are derived from current business plans which are developed using metal price assumptions; estimates of costs; resource, and exploration potential estimates, including timing and costs to develop and produce the material; and the use of discount rates in the measurement of fair value. These estimates generally rely on scientific and economic assumptions, which in some instances may not be correct, and could result in the expenditure of substantial amounts of money on a deposit before it can be determined whether or not the deposit contains economically recoverable mineralization.

Income taxes

The provision for income taxes which is included in the consolidated statements of operations and comprehensive loss and composition of deferred income tax liabilities included in the consolidated statements of financial position is based on factors such as tax rates in the different jurisdictions, changes in tax law and management’s assessment of future results and have not yet been confirmed by the taxation authorities. The Company does not recognize deferred tax assets where management does not expect such assets to be realized based on current forecasts.

In the event that actual results differ from these estimates, adjustments are made in future periods and changes in the amount of amount of deferred tax assets recognized may be required. These adjustments could materially impact the financial position and income (loss) for the period.

The utilization of U.S. net operating loss carryforwards, tax credit carryforwards, and recognized built-in losses may be subject to limitation under the rules regarding a change in stock ownership as determined by the Internal Revenue Code and state tax laws. Section 382 of the Internal Revenue Code of 1986, as amended, imposes annual limitations on the utilization of net operating loss carryforwards, tax credit carryforwards, and certain built-in losses upon an ownership change as defined under that Section. Generally, an ownership change may result from transactions that increase the aggregate ownership of certain shareholders in the Company’s stock by more than 50 percentage points over a three-year testing period. If the Company experiences an ownership change, an annual limitation would be imposed on certain of the Company’s tax attributes, including net operating losses and certain other losses, credits, deductions or tax basis. Based on management’s calculations, the Company does not expect any of its U.S. tax attributes to expire unused as a result of the Section 382 annual limitations. However, the annual limitations may impact the timeframe over which the net operating loss carryforwards can be used, potentially impacting cash tax liabilities in a future period. We continue to maintain a full valuation allowance on our U.S. net deferred tax assets since it is more likely than not that the related tax benefits will not be realized.
