ROTTENSTONE GOLD INC. CLOSES PREVIOUSLY ANNOUNCED FINANCING

Rottenstone Gold Inc. today closed a non-brokered common share unit financing by way of the issuance of two million units at a price of five cents per unit (see the news release by the issuer dated April 30, 2025). Each unit consisted of one common share of the corporation and one transferable common share purchase warrant that in turns entitles the holder of a warrant, upon further payment to Rottenstone Gold, to acquire one additional common share of the corporation at an exercise price of six cents per warrant share on any date prior to the date that is 60 months following the closing date of the financing. The financing and its terms are governed by policies of the Canadian Securities Exchange, on which the issuer is listed.

Rottenstone Gold intends to use the proceeds of the financing for near-term working capital.

There were no finders' fees paid by the corporation under the financing.

The units issued under the financing remain subject to any requisite regulatory approval and will be placed under a statutory hold period, being a four-month-and-one-day hold period pursuant to applicable securities laws of Canada.

Rottenstone Gold has 29,236,400 common shares issued and outstanding following completion of the financing.

Rottenstone project

Among other uses, the company has deployed working capital during 2025 to stake incremental dispositions for its Rottenstone project in Saskatchewan, including, as example, those activities highlighted within monthly activity reports filed by the corporation and found on its Canadian Securities Exchange disclosure hall. In the ordinary course, the corporation is continuing to evaluate areas that may, where appropriate, provide opportunity to augment its Rottenstone project in a cost-effective manner, principally on a Crown fee basis. Rottenstone Gold favourably views its disposition holdings in Saskatchewan's Rottenstone domain, from which it garners it corporate name, and is closely monitoring third party developments in the region.

Multilateral Instrument 61-101 disclosure

One insider of Rottenstone Gold (as that term is defined by securities regulations), being an officer/director, participated both directly and indirectly in the financing, and purchased an aggregate of $100,000 in units from the corporation. To public disclosure and during the past 12 months, the participating insider has not received any cash compensation for his executive roles with the corporation. The participation by such insider (the provision of working capital to the corporation through the financing) is still considered a related party transaction within the meaning of MI 61-101, Protection of Minority Security Holders in Special Transactions. The corporation has relied on exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(b) and 5.7(1)(b), respectively, of MI 61-101, as no securities of the corporation are listed or quoted on the Toronto Stock Exchange, Aequitas NEO Exchange Inc., the New York Stock Exchange, the American Stock Exchange, the Nasdaq Stock Market or a stock exchange outside of Canada, and neither the fair market value of the units to be acquired by the participating insider nor the consideration to be paid by such insider exceeds $2.5-million. The corporation did not file a material change report more than 21 days before the expected closing of the financing as the details of the participation therein by related parties of the corporation were not settled until shortly prior to closing of the financing and the corporation wished to close on an expedited basis for sound business reasons.
