FOX RIVER ANNOUNCES AMENDED INTERIM ORDER

Fox River Resources Corp. has been informed that the Ontario Superior Court of Justice (commercial list) has issued an amendment to the interim order of the court dated May 21, 2026, to remove the requirement that only registered shareholders of common shares as of the record date of May 14, 2026, may exercise their dissent rights in connection with the proposed plan of arrangement involving Fox River and Avenir Minerals Ltd.

The effect of the amended interim order is to extend dissent rights in accordance with Section 190 of the Canada Business Corporations Act, as modified by the interim order, to each registered shareholder at the time dissent rights are otherwise validly exercised, irrespective of whether that shareholder was a registered shareholder as of the close of business on the record date.

As previously announced, the company's special meeting of holders of common shares and other securities of the company will be held on June 23, 2026, to consider and, if deemed advisable, pass a special resolution approving the arrangement. If the requisite approval is obtained at the meeting, the company intends to apply to the court for a final order approving the arrangement. Additional information regarding the arrangement and the meeting is available in the management information circular dated May 21, 2026, which, together with the amended interim order, is available on SEDAR+ under Fox River's profile.
