GIANT MINING ANNOUNCES AUTOMATIC CONVERSION OF SPECIAL WARRANTS. PROSPECTUS SUPPLEMENT AVAILABLE ON SEDAR+

Giant Mining Corp. has filed a prospectus supplement dated July 17, 2025, to its short-form base shelf prospectus dated May 29, 2025, to qualify the distribution of securities underlying 15,187,293 special warrants issued by the company on June 27, 2025.

The prospectus supplement qualifies the distribution of 15,187,293 common shares and 15,187,293 common share purchase warrants comprising the units of the company issuable on the exercise or deemed exercise of the special warrants in the provinces of British Columbia, Alberta and Ontario. Each warrant entitles the holder thereof to acquire one common share at an exercise price of 32 cents until 4 p.m. Pacific Time on the date that is four years following the closing date of the offering. The warrants are subject to an accelerated expiry if the trading price of the common shares on the Canadian Securities Exchange, or such other market as the common shares may trade from time to time, is or exceeds 80 cents for any five consecutive trading days, in which event the warrantholder may, at the company's election, be given notice by way of a news release that the warrants will expire 30 days following the date of such notice. The warrants may be exercised by the warrantholder during the 30-day period between the notice and the expiration of the warrants.

The special warrants will be deemed to be converted into common shares and warrants on July 22, 2025. No action is required on the part of any holder of special warrants to convert their special warrants into underlying securities.

The qualification rights of holders of special warrants are further described in the prospectus supplement and the shelf prospectus, which can be found under the company's profile on SEDAR+.

Access to the shelf prospectus and the prospectus supplement and any amendment to the documents is provided in accordance with securities legislation relating to procedures for providing access to a shelf prospectus supplement, a base shelf prospectus and any amendment. The shelf prospectus and the prospectus supplement are accessible on SEDAR+. An electronic or paper copy of the prospectus supplement, the corresponding shelf prospectus and any amendment to the documents may be obtained, without charge, from the company at Suite 1500, 1055 West Georgia St., Vancouver, B.C., V6E 4N7, or by e-mail at info@giantminingcorp.com and by providing the contact with an e-mail address or address, as applicable.
