Basis of Presentation and Preparation

The consolidated financial statements are prepared by management in accordance with U.S. generally accepted accounting principles ("U.S. GAAP”) and are presented in US dollars. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.

Use of Estimates

The preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Significant estimates made by management in the accompanying consolidated financial statements include the adequacy of the Company’s reclamation and environmental obligation, valuation of deferred tax asset, and assessment of impairment of mineral properties.

Cash and Cash Equivalents

All highly liquid investments with maturities of three months or less at the date of purchase are classified as cash and cash equivalents. The carrying amount of these securities approximates fair value because of the short-term maturity of these instruments.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents. The Company maintains cash in accounts which may, at times, exceed federally insured limits. At June 30, 2025 and 2024, the Company had $1.1 million and $5.2 million, respectively, of balances in excess of federally insured limits. The Company deposits its cash with financial institutions which it believes have sufficient credit quality to minimize the risk of loss.

Fair Value Measurements

The Company has adopted FASB ASC 820, Fair Value Measurements and Disclosures, which defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The Company has adopted FASB ASC 825, Financial Instruments, which allows companies to choose to measure eligible financial instruments and certain other items at fair value that are not required to be measured at fair value. The Company has not elected the fair value option for any eligible financial instruments.

Stock Based Compensation

Stock-based compensation cost is measured at the grant date and based on the calculated fair value of the award. For grants to employees an expense is recognized over the employee’s requisite service period (generally the vesting period of the equity grant) using the graded vesting method. For grants to non-employees, an expense is recognized when the good or service is received.

For options with performance conditions, the Company accrues compensation if it is probable that the performance condition will be achieved and recognizes the compensation cost over the requisite service period. The requisite service period for options with performance conditions is estimated based on the analysis of the terms of the award and the specific performance conditions. The

Company shall recognize the effect of forfeited awards in compensation cost when they occur. New shares of the Company’s common stock will be issued for any options exercised.

The fair value of Restricted Share Units ("RSUs") and stock awards are based on the Company's stock price on the day of grant. Stock based compensation expense related to RSUs and stock awards is generally recognized over the requisite service period using the graded vesting method. Vesting dates for RSUs with performance conditions are determined by an analysis of the implicit service period of the performance target. The Company shall recognize the effect of forfeited awards in compensation cost when they occur. New shares of the Company's common stock will be issued for any RSUs that vest to the recipient.

Mineral Properties

Mineral property acquisition costs are capitalized when incurred and will be amortized using the units-of-production method over the estimated life of the reserve following the commencement of production. If a mineral property is subsequently abandoned or impaired, any capitalized costs will be expensed in the period of abandonment or impairment.

Acquisition costs include cash consideration and the fair market value of shares issued on the acquisition of mineral properties. Net proceeds from the sale of royalties are deducted from the carrying value of the mineral properties.

The recoverability of the carrying values of our mineral property is dependent on the ability of the Company to advance the projects to production, upon future profitable production or from proceeds from the sale of properties or production royalties. If the Company is unable to obtain additional funding, we may be unable to continue its operations, and amounts realized for assets may be less than amounts reflected in these consolidated financial statements.

Exploration Costs

Exploration costs, which include maintenance, development and exploration of mineral claims, are expensed as incurred. When it is determined that a mineral deposit can be economically developed as a result of establishing proven and probable reserves and all regulatory operating permits have been secured, the costs incurred after such determination will be capitalized until the commencement of production and amortized over their useful lives. To date, the Company has not established the commercial feasibility and received the necessary regulatory operating permits for any of its exploration prospects; therefore, all exploration costs are being expensed.

Property and Equipment

Equipment is recorded at cost less accumulated depreciation. All equipment is depreciated over its estimated useful life.

Impairment of Long-Lived Assets

The Company tests long-lived assets or asset groups for recoverability when events or changes in circumstances indicate that their carrying amount may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed significantly before the end of its estimated useful life.

The Company assesses the carrying value of mineral properties for whenever information or events indicate the potential for impairment. This would include our inability to obtain all the necessary regulatory permits to build and operate mines related to our mineral properties, government actions, the results of exploration activities and technical evaluations and changes in key economic conditions such as the price of gold and silver or key inputs to the building and operating of a mine including initial capital, yearly production levels and operating expenses. We compare estimated future net cash flows with our carrying costs and future obligations on an undiscounted basis. The undiscounted cash flows are based on the amounts we expect to receive from the sale of gold and silver produced from the mine, the level of operating expenses we expect to incur to produce the gold and silver that is recovered from the mineral deposit and the level of capital expected to build, operate and sustain the mine operations. If it is determined that the estimated future undiscounted cash flows are less than the carrying value of the property, a write-down to the estimated fair value will be reported in our Consolidated Statement of Operations for the period. There has been no impairment of our mineral properties for the fiscal years-ended June 30, 2025 and 2024.

Reclamation and Environmental Obligation

The Company follows the provisions of ASC 410, “Asset Retirement and Environmental Obligations”, which establishes the standards for the initial measurement and subsequent accounting for obligations associated with the sale, abandonment, or other disposal of long-lived tangible assets arising from the acquisition, construction or development and for normal operations of such assets. The fair value of a liability for an asset retirement obligation will be recognized in the period in which it is incurred if a reasonable estimate of

fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset. An accretion cost, representing the increase over time in the present value of the liability, is recorded each period. As reclamation work is performed or liabilities are otherwise settled, the recorded amount of the liability is reduced. Future reclamation costs are accrued based on management’s best estimate at the end of each period of the discounted costs expected to be incurred for the asset. Such costs include facilities removal, earthworks, revegetation and on-going monitoring. Changes in estimates are reflected prospectively in the period an estimate is revised.

Net Loss per Share

Basic loss per share is computed by dividing net loss available to common shareholders by the weighted average number of shares outstanding during each period. Diluted loss per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

For the years ended June 30, 2025 and 2024, the shares of common stock equivalents related to outstanding stock options, restricted share units have not been included in the diluted per share calculation as they are anti-dilutive as the Company has recorded a net loss from continuing operations for each year.

Leases

The Company determines if an arrangement is, or contains, a lease at the inception date. Right-of-use (“ROU”) assets related to operating leases are included in Other assets, non-current with related liabilities included in Accrued liabilities and Other long-term liabilities. ROU assets under finance leases, which primarily represent property and equipment, are included in Property, plant and equipment, net with related liabilities in debt, current and debt, non-current on the Consolidated Balance Sheet.

Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. Currently, the Company does not have any leases with terms greater than 12 months.

Convertible Debt

The Company reviews the terms of its convertible notes payable to determine whether to account for any portion of the proceeds towards the conversion feature. In general, when the convertible notes instrument has the following characteristics and terms no portion of the proceeds from the issuance shall be accounted for as attributable to the conversion feature: a) is convertible into common stock of the Company at a specified price at the option of holder; b) the debt is sold at a price or has value at issuance not significantly in excess of the face amount; c) an interest rate that is lower than the Company could establish for nonconvertible debt; d) an initial conversion price that is greater than the fair value of the common stock at time of issuance and; e) a conversion price that does not decrease except pursuant to antidilution provisions. When proceeds are not attributable to the conversion features of the debt, the Company records the entire amount as a liability. If the fair value option is not elected, the Company will reduce the initial carrying amount of the debt by any direct and incremental issuance costs paid to third parties that are associated with the convertible debt issuance.

The Company also reviews the terms of its convertible notes payable to determine whether there are embedded derivatives, including the embedded conversion option, that are required to be bifurcated and accounted for as individual derivative financial instruments. In circumstances where convertible debt contains embedded derivatives that are required to be separated from the host contracts, the total proceeds received are first allocated to the fair value of the derivative financial instruments determined using the binomial model. The remaining proceeds, if any, are then allocated to the debenture cost contracts, usually resulting in those instruments being recorded at a discount from their principal amount. This discount is accreted over the expected life of the instruments to profit (loss) using the effective interest method.

The debenture host contracts are subsequently recorded at amortized cost at each reporting date, using the effective interest method. The embedded derivatives are subsequently recorded at fair value at each reporting date, with changes in fair value recognized in profit (loss).

Derivative Liability

The Company reviews the terms of its convertible loans to determine whether there are embedded derivatives that are required to be bifurcated and accounted for as individual derivative financial instruments. The Company determined that a conversion feature embedded in its convertible loan is required to be accounted for separately from the convertible loan as a derivative liability and recorded at fair value and the remaining value allocated to the convertible loan net the unamortized debt issuance costs. The

derivative liability will be fair valued at each reporting period, with changes in fair value recorded as a gain or loss in the Consolidated Statement of Operations.

Income Taxes

Income taxes are determined using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. In addition, a valuation allowance is established to reduce any deferred tax asset for which it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized.

Potential benefits of income tax losses are not recognized in the accounts until realization is more likely than not. Potential benefits of net operating losses have not been recognized in these financial statements because the Company cannot be assured it is more likely than not it will utilize the net operating losses carried forward in future periods; and accordingly is offset by a valuation allowance.

To the extent interest and penalties may be assessed by taxing authorities on any underpayment of income tax, such amounts would be accrued and classified as a component of income tax expense in our Consolidated Statements of Operations and Comprehensive Loss.
