Critical Accounting Estimates

Previous report

The Company has three critical accounting estimates. The ounces of gold contained in process and concentrate inventory is based on assays taken at the time the ore is processed and the ounces of gold contained in shipped concentrate which is based upon assays taken prior to shipment, however, subject to final assays at the refinery, these shipments are also subject to the fluctuation in gold prices between shipment date and estimated and actual final settlement date. Additionally, the reclamation bond obligation on the Company’s balance sheet is based on an estimate of the future cost to recover and remediate its properties as required by permits upon cessation of operations and may differ when operations are actually ceased. Finally, the amortization of development costs at the Golden Chest Mine is based on an estimate of reserves and measured and indicated resources calculated annually by the Company’s mine engineers.

The Company’s concentrate sales sometimes involve variable consideration, as they can be subject to changes in metals prices between the time of shipment and their final settlement. However, the Company can reasonably estimate the transaction price for the concentrate sales at the time of shipment using forward prices for the estimated month of settlement, and previously recorded sales and accounts receivable are adjusted to estimated settlement metals prices until final settlement for financial reporting purposes. The embedded derivative contained in the Company’s concentrate sales is adjusted to fair value through earnings each period prior to final settlement. It is unlikely a significant reversal of revenue for the concentrate receivable will occur upon final settlement of the lots. As such, the Company uses the expected value method to price the concentrate until the final settlement date occurs, at which time the final transaction price is known. At March 31, 2026, metals that had been sold but not finally settled included 7,819 ounces of which 7,102 ounces were sold at a predetermined price with the remaining 717 exposed to future price changes until prices are locked in based on the month of settlement. The Company has received provisional payments on the sale of these ounces with the remaining amount due reflected in gold sales receivable.

Previous report

The asset retirement obligation and asset on the Company’s balance sheet is based on an estimate of the future cost to recover and remediate its properties as required by permits upon cessation of operations and may differ when operations are actually ceased. At March 31, 2026 the Company reviewed its December 31, 2025 estimate that the cost of the machine and man hours probable to be needed to put its properties in the condition required by permits once operations are ceased. The March 31, 2026 estimated costs would be $104,000 for the Golden Chest Mine property and $224,000 for the New Jersey Mine and Mill. For purposes of the estimate, the Company evaluated the expected life in years and costs that, initially, are comparable to rates that it would incur at the present. An expected present value technique is used to estimate the fair value of the liability. This includes inflating the estimated costs in today’s dollars using a reasonable inflation rate up to the date of expected retirement and discounting the inflated costs using a credit-adjusted risk-free rate. Upon initial recognition of the liability, the carrying amount of the related long-lived asset is increased by the same amount. The liability is accreted over time through periodic charges to earnings. In addition, the asset retirement cost is amortized over the life of the related asset. The Company is adding to the liability each year, and amortizing the asset over the estimated life, which decreases net income in total each year. Changes resulting from revisions to the timing or amount of the original estimate of undiscounted cash flows are recognized as either an increase or a decrease in the carrying amount of the liability for an asset retirement obligation and the related asset retirement cost capitalized as part of the carrying amount of the related long-lived asset. Upward revisions of the amount of undiscounted estimated cash flows are discounted using the current credit-adjusted risk-free rate. Downward revisions in the amount of undiscounted estimated cash flows are discounted using the credit-adjusted risk-free rate that existed when the original liability was recognized. The Company reviews, on an annual basis, unless otherwise deemed necessary, the asset retirement obligations. Separately, the Company accrues costs associated with environmental remediation obligations when it is probable that such costs will be incurred and able to be reasonably estimated.

Amortization of development costs is calculated using the units-of-production method over the expected life as per the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 360-10-35-4. This includes the cost to define proven and probable reserves and measured and indicated resources accessible via the Main Access Ramp (“MAR”). Measured resources are 90-100% interpolated, and indicated resources 75-80% interpolated, using a 2 grams per tonne gold cut-off grade at the diluted minimum mining width. Conservative estimation parameters (three samples within 25 meters for measured, two within 50 meters for indicated) and economic factors ensure viability. Inferred resources are excluded to reduce uncertainty, and therefore, the volumes are risk-adjusted. Assumptions are regularly evaluated, with material deviations disclosed to ensure a systematic and rational cost allocation. More information on the Company’s reserves and resources can be found in the Technical Report Summary For the Golden Chest Mine which was included as Exhibit 96.1 to the Company’s Form 10-K filed with the Securities and Exchange Commission on March 23, 2026.
