The Company announced that it has closed its previously announced Offering for aggregate gross proceeds of $36,085,000. The Offering was led by Stifel Nicolaus Canada Inc., as lead underwriter and sole bookrunner, together with National Bank Financial Inc., Paradigm Capital Inc. and Canaccord Genuity Corp. (the “Underwriters”).

In connection with the Offering, the Company issued: (i) 28,409,090 charity flow-through shares (the “CFT Shares”) at a price of $0.44 per CFT Share for total gross proceeds of $12,500,000; (ii) 40,322,580 hard dollar common shares (the “HD Shares”) at a price of $0.31 per HD Share for total gross proceeds of $12,500,000; (iii) 26,315,790 flow-through common shares (the “FT Shares”), at a price of $0.38 per FT Share for total gross proceeds of $10,000,000; and (iv) 3,500,000 hard dollar common shares (the “Hold Shares” and together with the FT Shares, HD Shares and CFT Shares, the “Offered Shares”) at a price of $0.31 per Hold Share for total gross proceeds of $1,085,000. The issuance of FT Shares and the CFT Shares will entitle the holders thereof to receive the tax benefits applicable to flow-through shares, in accordance with provisions of the Income Tax Act (Canada) (the “Act”). The CFT Shares were purchased by the initial purchasers, who intend to sell the CFT Shares to end purchasers.

Gross proceeds from the sale of CFT Shares and FT Shares will be used to incur eligible “Canadian exploration expenses” that qualify as flow-through mining expenditures, as defined in the Act (“Qualifying Expenditures") related to the Company's Moss Gold Project in Ontario, on or before December 31, 2026, and to renounce all the Qualifying

Expenditures in favour of the purchasers of the FT Shares and the CFT Shares effective December 31, 2025.

The CFT Shares and the HD Shares were offered to purchasers resident in all provinces and territories of Canada (excluding Quebec) pursuant to the listed issuer financing exemption under Part 5A (the “Listed Issuer Financing Exemption”) of National Instrument 45-106 – Prospectus Exemptions (“NI 45-106”). Offered Shares sold pursuant to the Listed Issuer Financing Exemption in Canada are not subject to resale restrictions under applicable Canadian securities laws and policies of the TSX Venture Exchange (“TSXV”). The Offered Shares may be re-offered or re-sold on a private placement basis in offshore jurisdictions as permitted and in the United States pursuant to an exemption from the registration requirements of the United States Securities Act of 1933 (the “U.S. Securities Act”), as amended. The FT Shares and Hold Shares were offered to purchasers resident in all provinces and territories of Canada pursuant to other applicable exemptions from the prospectus requirements of NI 45-106.

The FT Shares and Hold Shares issued under the Offering have a hold period of four months and one day from the date of closing. The securities described herein have not been, and will not be, registered under the U.S. Securities Act, or any state securities laws, and accordingly may not be offered or sold within the United States except in compliance with the registration requirements of the U.S. Securities Act and applicable state securities requirements or pursuant to exemptions therefrom. This press release does not constitute an offer to sell or a solicitation to buy any securities in any jurisdiction.

In connection with the Offering, the Underwriters received a cash commission of $2,038,394.59. Eventus Capital Corp. is an advisor to the Company.

Brian Paes-Braga (the “Acquiror”) purchased 3,500,000 Hold Shares for total consideration paid by Acquiror of $1,085,000, the Acquiror has beneficial ownership, control or direction of 45,580,500 common shares representing 9.80% of the issued and outstanding common shares, and would have beneficial ownership, control or direction of 45,780,500 common shares representing 9.84% of the common shares on a partially diluted basis assuming the conversion of the Acquiror’s restricted share units (“RSUs”) and stock options. The Acquiror has beneficial ownership of 80,000 RSUs and 120,000 stock options. Prior to the Offering, the Acquiror had beneficial ownership, direction or control of 42,080,500 common shares, representing 11.48% of the issued and outstanding common shares. The Company has been advised that the Acquiror acquired these securities for investment purposes and their acquisition will be disclosed in an early warning report to be filed under the Company’s SEDAR+ profile. The Acquiror may in the future acquire or dispose of securities of the Company through the market, privately or otherwise, as circumstances or market conditions warrant. Additionally, as a result of common share issuances by the Company, including the Offering, Lutry Investments Limited has beneficial ownership, control or direction over less than 10% of the Company’s outstanding common shares. Lutry Investments Limited has beneficial ownership, control or direction of 34,674,083

common shares representing 7.46% of the issued and outstanding common shares following the completion of the Offering.

Related parties of the Company purchased an aggregate of 4,422,580 common shares in the Offering. The issuance of such securities to these related parties are each considered to be a related party transaction within the meaning of TSXV Policy 5.9 – Protection of Minority Security Holders in Special Transactions (“Policy 5.9”) and Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company has relied on the exemptions from the valuation and minority shareholder approval requirements of MI 61-101 (and Policy 5.9) as the fair market value of the securities issued to such parties does not exceed 25% of the Company's market capitalization.

DuMoulin Black LLP acted as counsel for the Company and Wildeboer Dellelce LLP acted as counsel for the Underwriters.

The Offering remains subject to the final approval of the TSXV.

Not applicable.
