NATURE OF OPERATIONS AND GOING CONCERN The principal business activity of Opus One Gold Corporation (the "Company" or "Opus") is the acquisition and exploration of exploration and evaluation assets, primarily in Canada. The Company was incorporated in British Columbia on August 29, 1979 and was continued under the Canada Business Corporations Act on July 13, 2012. The Company’s head office is located at 2075 Victoria Avenue., Suite 220, Saint-Lambert, Qc., Cana --- da. These financial statements have been prepared on the basis of accounting principles applicable to a going concern, which assumes that the Company will be able to continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The Company does not generate sufficient cash flow from operations to adequately fund its activities and has therefore relied principally upon the support of creditors, related parties and issuance of securities for financing. Future capital requirements will depend on many factors including the Company's ability to execute its business plan. The Company intends to continue relying upon the issuance of securities to finance its future activities but there can be no assurance that such financing will be available on a timely basis under terms acceptable to the Company. Although these financial statements do not include any adjustments that may result from the inability to secure future financing, such a situation would have a material adverse effect on the Company's recoverability of assets, classification of assets and liabilities, and results of operations should the Company be unable to continue as a going concern. The business of mining and exploration involves a high degree of risk and there can be no assurance that current exploration programs will result in profitable mining operations. The Company has no source of operating revenue and has significant cash requirements to meet its administrative overhead and maintain its exploration and evaluation assets. The recoverability of amounts shown for exploration and evaluation assets is dependent on several factors. These include the discovery of economically recoverable reserves, the ability of the Company to obtain the necessary financing to complete the development of these properties, and future profitable production or proceeds from disposition of exploration and evaluation assets. The carrying value of the Company's exploration and evaluation assets do not reflect current or future values. The Company has not yet determined whether its exploration and evaluation assets contain economically recoverable ore reserves. The recovery of the amounts comprising exploration and evaluation assets are dependent upon the confirmation of economically recoverable reserves, the ability of the Company to obtain necessary financing to successfully complete the exploration and development of those reserves and upon future profitable production or, alternatively, upon the Company's ability to dispose of its interest on an advantageous basis. The Company estimates that additional funding will be required to continue operations and planned exploration activites over the next 12 months. These material uncertainties may cast doubt upon the entity's ability to continue as a going concern. February 28, 2026 August 31, 2025 Deficit $ (22,145,702) $ (21,540,185) Working capital (deficiency) $ 1,001,993 $ (84,123) 6 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION Statement of Compliance These financial statements have been prepared in accordance with IFRS Accounting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The Board of Directors approved the financial statements on April _ --- _, 2026. Basis of presentation These financial statements have been prepared on an accrual basis and are based on the historical costs, except for certain financial instruments which are measured at fair value. The financial statements are presented in Canadian dollars, which is also the Company's functional currency. Use of estimates The preparation of these financial statements in conformity with IFRS requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported revenues and expenses during the year. Although management uses historical experience and its best knowledge of the amount, events or actions to form the basis for judgments and estimates, actual results may differ from these estimates. The most significant accounts that require estimates as the basis for determining the stated amounts include the recoverability of exploration and evaluation assets, valuation of share-based compensation and other equity-based payments, the recoverability, and the accrual of refundable mining tax credits. Key estimates made in applying accounting policies that have the most significant effects on the amounts recognized in the financial statements are as follows: Economic recoverability and probability of future economic benefits of exploration and evaluation assets Management has determined that exploration, evaluation, and related costs incurred which were capitalized may have future economic benefits and may be economically recoverable. Management uses several criteria in its assessments of economic recoverability and probability of future economic benefits including, geologic and other technical information, a history of conversion of mineral deposits with similar characteristics to its own properties to proven and probable mineral reserves, the quality and capacity of existing infrastructure facilities, evaluation of permitting and environmental issues and local support for the project. Valuation of share-based compensation The Company uses the Black-Scholes Option Pricing Model for valuation of share-based compensation. Option pricing models require the input of subjective assumptions including expected price volatility, interest rate, and forfeiture rate. Changes in the input assumptions can materially affect the fair value estimate and the Company's profit or loss and equity reserves. 7 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Use of estimates (cont’d) Accrual of refundable mining tax credits The provincial government of Quebec provides for a refundable tax on net qualified mining exploration expenditures incurred in Quebec. The credit is calculated as a percentage of qualified mining exploration expenses. Management has estimated and accrued the likely refundable amount arising from expenditures incurred. Exploration and evaluation assets Pre-acquisition costs are expensed as incurred. Costs directly related to the exploration and evaluation of mineral properties are capitalized once the legal rights to explore the mineral properties are acquired or obtained. When the technical and commercial viability of a mineral resource have been demonstrated and a development decision has been made, the capitalized costs of the related property a --- re first tested for impairment and then transferred to mining assets and amortized on a units of production basis following commencement of commercial production. If it is determined that capitalized acquisition, exploration and evaluation costs are not recoverable, or the property is abandoned or management has determined an impairment in value, the property is written down to its recoverable amount. Exploration and evaluation assets are reviewed for impairment when facts and circumstances suggest that the carrying amount may exceed its recoverable amount. The costs include the cash or other consideration and the assigned value of shares issued, if any, on the acquisition of exploration and evaluation assets. Costs related to properties acquired under option agreements or joint ventures, whereby payments are made at the sole discretion of the Company, are recorded in the accounts at such time as the payments are made. The Company does not accrue estimated future costs of maintaining its exploration and evaluation assets in good standing. Capitalized costs as reported on the statements of financial position represent costs incurred to date and may not reflect actual, present, or future values. Recovery of carrying value is dependent upon future commercial success or proceeds from disposition of the exploration and evaluation property interests. Management evaluates each mineral interest on a reporting period basis or as events and circumstances warrant, and makes a determination based on exploration activity and results, estimated future cash flows and availability of funding as to which costs are capitalized or charged as impairment charges. Write-downs due to impairment in value are charged to profit or loss. Exploration and evaluation assets, where future cash flows are not reasonably determinable, are evaluated for impairment based on results of exploration work, management's intentions and determination of the extent to which future exploration programs are warranted and likely to be funded. General exploration costs not related to specific properties and general administrative expenses are charged to profit or loss in the year in which they are incurred. Restoration and environmental obligations The Company recognizes liabilities for statutory, contractual, constructive or legal obligations associated with the retirement of long-term assets, when those obligations result from the acquisition, construction, development or normal operation of the assets. The net present value of future restoration cost estimates arising from the decommissioning of plant and other site preparation work is capitalized to exploration and evaluation assets along with a corresponding increase in the restoration provision in the period incurred. Discount rates using a pre-tax rate that reflect the time value of money are used to calculate the net present value. The restoration asset will be depreciated on the same basis as other mining assets. 8 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Restoration and environmental obligations (cont'd...) The Company's estimates of restoration costs could change as a result of changes in regulatory requirements, discount rates and assumptions regarding the amount and timing of the future expenditures. These changes are recorded directly to the --- related asset with a corresponding entry to the restoration provision. The Company's estimates are reviewed annually for changes in regulatory requirements, discount rates, effects of inflation and changes in estimates. Changes in the net present value, excluding changes in amount and timing of the Company's estimates of reclamation costs, are charged to profit or loss for the period. The net present value of restoration costs arising from subsequent site damage that is incurred on an ongoing basis during production are charged to profit or loss in the period incurred. For the years presented, there were no significant restoration and environmental obligations. Mining and exploration tax recoveries The Company recognizes mining and exploration tax recoveries in the period in which the related qualifying resource expenditures are incurred. The amount recoverable is subject to review and approval by the taxation authorities and is adjusted for in the period when such approval is confirmed. Impairment of assets The carrying amount of the Company's assets (which include exploration and evaluation interests) is reviewed at each reporting date to determine whether there is any indication of impairment. If such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss. An impairment loss is recognized whenever the carrying amount of an asset or its cash generating unit exceeds its recoverable amount. Impairment losses are recognized in profit or loss. The recoverable amount of assets is the greater of an asset's fair value less cost to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects the current market assessments of the time value of money and the risks specific to the asset. For an asset that does not generate cash inflows largely independent of those from other assets, the recoverable amount is determined for the cash-generating unit to which the asset belongs. An impairment loss is only reversed if there is an indication that the impairment loss may no longer exist and there has been a change in the estimates used to determine the recoverable amount, however, not to an amount higher than the carrying amount that would have been determined had no impairment loss been recognized in previous years. Assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment. Share capital Financial instruments issued by the Company are classified as equity only to the extent that they do not meet the definition of a financial liability or financial asset. The Company's common shares, share purchase warrants, and stock options are classified as equity instruments. Incremental costs directly attributable to the issue of new shares or options are recognized as a deduction from equity, net of tax. 9 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Valuation of equity units issued in private placements: The Company uses a residual value method with respect to the measurement of shares and warrants issued as private placement units. The residual value method first allocates value to the more easily measurable component based on fair value and then the residual valu --- e, if any, to the less easily measurable component. The fair value of the common shares issued in private placements is determined to be the more easily measurable component and are valued at their fair value, as determined by the closing price on the issuance date, the balance, if any, is allocated to the attached warrants. Any value attributed to the warrants is recorded to reserves. Share-based compensation The Company uses the fair value-based method of accounting for stock options granted to directors for compensatory warrants. Under this method, the fair value of the stock options and compensatory warrants are determined using the Black-Scholes option pricing model. The fair value of stock options is recognized to expense over the vesting period. The fair value of share-based compensation to non-employees is measured at the date the goods or services are received, at either the fair value of the goods or services received or the fair value of the equity instruments issued using the Black-Scholes option pricing model, if the fair value of the goods or services received cannot be readily measured. Basic and diluted loss per share Basic earnings (loss) per share is computed by dividing net earnings (loss) available to common shareholders by the weighted average number of shares outstanding during the reporting period. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share except that the weighted average shares outstanding are increased to include additional shares for the assumed exercise of stock options and warrants, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and warrants were exercised and that the proceeds from such exercises were used to acquire common stock at the average market price during the reporting periods. Financial instruments Financial assets The Company classifies its financial assets in the following categories: at fair value through profit or loss (“FVTPL”), at fair value through other comprehensive income (“FVTOCI”) or at amortized cost. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition. Financial assets at FVTPL Financial assets carried at FVTPL are initially recorded at fair value and transaction costs are expensed to profit or loss. Realized and unrealized gains and losses arising from changes in the fair value of the financial asset held at FVTPL are included in profit or loss in the period in which they arise. The Company has no assets classified as FVTPL. Financial assets at FVTOCI Investments in equity instruments at FVTOCI are initially recognized at fair value plus transaction costs. Subsequently they are measured at fair value, with gains and losses arising from changes in fair value recognized in other comprehensive income. There is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. The Company does not have any financial assets classified as FVTOCI. 10 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Financial instruments (cont'd...) Financial assets (cont'd...) Financial assets at amortized cost Financial assets at amortized cost are initial --- ly recognized at fair value and subsequently carried at amortized cost less any impairment. They are classified as current assets or non-current assets based on their maturity date. Gains and losses on derecognition of financial assets classified as amortized cost are recognized in profit or loss. Gains or losses on financial assets classified as FVTOCI remain within accumulated other comprehensive income. Cash and receivables have been classified and measured at amortized cost. Impairment of financial assets The Company assesses at each reporting date whether a financial asset is impaired. The Company recognizes a loss allowance for expected credit losses on financial assets that are measured at amortized cost. At each reporting date, the loss allowance for the financial asset is measured at an amount equal to the lifetime expected credit losses if the credit risk on the financial asset has increased significantly since initial recognition. If at the reporting date, the financial asset has not increased significantly since initial recognition, the loss allowance is measured for the financial asset at an amount equal to twelve month expected credit losses. For trade receivables the Company applies the simplified approach to providing for expected credit losses, which allows the use of a lifetime expected loss provision. Impairment losses on financial assets carried at amortized cost are reversed in subsequent periods if the amount of the loss decreases and the decrease can be objectively related to an event occurring after the impairment was recognized. b) Financial liabilities The Company classifies its financial liabilities in the following categories: financial liabilities at amortised cost and FVTPL. Financial liabilities at amortised cost Financial liabilities classified as amortised cost are initially recognized at fair value less directly attributable transaction costs. After initial recognition, financial liabilities at amortised cost are subsequently measured at amortized cost using the effective interest method. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or, where appropriate, a shorter period. The Company’s accounts payable and accrued liabilities and, amounts due to related parties are classified and measured at amortised cost. FVTPL Financial liabilities classified as FVTPL include financial liabilities held for trading and financial liabilities designated upon initial recognition as FVTPL. Derivatives, including separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments. Fair value changes on financial liabilities classified as FVTPL are recognized through profit or loss. The Company has not classified any financial liabilities as FVTPL. For the years presented, the Company did not have any derivative financial assets and liabilities. 11 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Leases At inception of a contract, the Company assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease --- if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company assesses whether the contract involves the use of an identified asset, whether it has the right to obtain substantially all of the economic benefits from use of the asset during the term of the arrangement and if it has the right to direct the use of the asset. As a lessee, the Company recognizes a right-of-use asset, and a lease liability at the commencement date of a lease. The right-of-use asset is initially measured at cost, which is comprised of the initial amount of the lease liability adjusted for any payments made at or before the commencement date, plus any decommissioning and restoration costs, less any lease incentives received. The right-of-use asset is subsequently depreciated from the commencement date to the earlier of the end of the lease term, or the end of the useful life of the asset. In addition, the right-of-use asset may be reduced due to impairment losses, if any, and adjusted for certain measurements of the lease liability. A lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by the interest rate implicit in the lease, or if that rate cannot be readily determined, the incremental borrowing rate. Lease payments included in the measurement of the lease liability are comprised of: o fixed payments, including in-substance fixed payments, less any lease incentives receivable; o variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date; o amounts expected to be payable under a residual value guarantee; o exercise prices of purchase options if it is reasonably certain the option will be exercised; and o payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease. The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, or if there is a change in our estimate or assessment of the expected amount payable under a residual value guarantee, purchase, extension or termination option. Variable lease payments not included in the initial measurement of the lease liability are charged directly to profit or loss. The Company does not recognize right-of-use assets and lease liabilities for short-term leases that have a lease term of 12 months or less and leases of low-value assets (below US $5,000). The lease payments associated with these leases are charged directly to profit or loss on a straight-line basis over the lease term. 12 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Income taxes Current income tax Current income tax assets and liabilities for the current period are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date, in the country where the Company operates and generates taxable income. Current income tax relating to items recognized directly in other comprehensive income or equity is r --- ecognized in other comprehensive income or equity and not in profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Deferred tax Deferred tax is provided for based on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. The carrying amount of deferred tax assets is reviewed at the end of each reporting period and recognized only to the extent that it is probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. Deferred tax assets and deferred tax liabilities are offset, if a legally enforceable right exists to set off current tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority. Newly adopted standards, interpretations and amendments New standards adopted during the year: IAS 1 – Presentation of Financial Statements: The amendments to IAS 1 provide a more general approach to the classification of liabilities based on the contractual agreement in place at the reporting date. These amendments are effective for reporting periods beginning on or after January 1, 2024, but did not have have a material impact on the Company. New accounting standards issued but not yet effective: IFRS 18 - Presentation and Disclosure in Financial Statements IFRS 18 is effective for reporting periods beginning on or after January 1, 2027. It introduces several new requirements that are expected to impact the presentation and disclosure of most, if not all, entities. The Company is in the process of assessing the impact on the financial statements of the new standard. 13 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Fair values Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of significant judgment, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair values. The fair value hierarchy has the following levels: Level 1 - quoted prices (unadjusted) in active markets for identical assets and liabilities; Level 2 - inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and Level 3 - inputs for the asset or liability that are not based on observable market data (unobservable inputs). The carrying values of cash, receivables, accounts payable and accrued liabilities, and due to related parties approximate their fair values due to the short-term maturity of these financial instruments. Financial instrument risk exposure and risk management Th --- e Board of Directors has overall responsibility for the establishment and oversight of the Company's risk management framework. The Company considers the fluctuations of financial markets and seeks to minimize potential adverse effects on financial performance. The Company is exposed in varying degrees to a variety of financial instrument related risks. The Board approves and monitors the risk management process. (a) Credit risk Credit risk is the risk of a financial loss to the Company if a counterparty to a financial instrument fails to meet its contractual obligation. The Company's exposure to credit risk includes cash and receivables. The Company manages credit risk, in respect of cash, by placing its cash with a major Canadian financial institution in accordance with the Company's investment policy. In regard to the receivables, the Company has a significant estimate of an amount due from governmental agencies, which based on past experience, has been both reasonable and collectible. Concentration of credit risk exists with respect to the Company's cash as all amounts are held at a single major Canadian financial institution. The Company's concentration of credit risk and maximum exposure thereto is considered minimal. The maximum exposure to credit risk is equal to the carrying value of the financial assets. 14 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026 and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2. MATERIAL ACCOUNTING POLICY INFORMATION (cont’d) Financial instrument risk exposure and risk management (cont'd...) (b) Liquidity risk Liquidity risk is the risk that the Company will encounter difficulty in obtaining funds to meet commitments. The Company's ability to continue as a going concern is dependent on management's ability to raise required funding through future equity issuances. The Company manages its liquidity risk by forecasting cash flows from operations and anticipating any investing and financing activities. Management and the Board of Directors are actively involved in the review, planning and approval of significant expenditures and commitments. The Company is exposed to liquidity risk. (c) Market risk Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risk comprises three types of risk: interest rate risk, foreign currency risk and commodity price risk. i. Interest rate risk The Company has cash balances which earn interest subject to fluctuations in the prime rate. The Company's current policy is to invest excess cash in investment-grade demand deposit certificates issued by its banking institutions. Management believes that interest rate risk is remote. A 1% change in the interest rate would have no significant impact on interest income reported at August 31, 2025. ii. Foreign currency risk The Company is not exposed to foreign currency risk as all monetary assets and liabilities are denominated in Canadian currency. 15 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 2.

CAPITAL RISK MANAGEMENT The Company manages common shares, stock options and share purchase warrants as capital. The Company's objectives when managing capital are to safeguard the Company's ability to continue as a going concern in order to pursue the development of its exploration and evaluation assets and to maintain a flexible capital structure which optimizes the costs of capital at an acceptable risk. The Company manages its capital structure and makes adjustments to it in light of economic conditions and the risk characteristics of the underlying assets. To maintain or adjust the capital structure, the Company may attempt to issue new shares, issue debt, acquire or dispose of assets, or adjust the amount of cash on hand. The Board of Directors does not establish a quantitative return on capital criteria for management but rather relies on the expertise of the Company's management to sustain future development of the business. The Company currently has no source of revenues. As such, the Company is dependent upon external financings to fund activities. In order to carry future projects and pay for administrative costs, the Company will spend its existing working capital and raise additional funds as needed. Management reviews its capital management approach on an ongoing basis and believes that this approach, given the relative size of the Company, is reasonable. There were no changes in the Company's approach to capital management during the period ended February 28, 2026. The Company is not subject to externally imposed capital requirements. 23 OPUS ONE GOLD CORPORATION NOTES TO THE FINANCIAL STATEMENTS SIX MONTHS ENDED FEBRUARY 28,2026 and 2025 (Unaudited – Prepared by Management) (Expressed in Canadian Dollars) 12.
