GRANITE CREEK OBTAINS SECURITYHOLDER APPROVAL FOR ARRANGEMENT

Granite Creek Copper Ltd. received securityholder approval for its previously announced plan of arrangement, pursuant to which, among other things, Cascadia Minerals Ltd. will acquire all of the issued and outstanding common shares of Granite Creek, following a vote at the special meeting of Granite Creek's securityholders held on Aug. 5, 2025. At the meeting, Granite Creek securityholders voted approximately 92 per cent in favour of the arrangement.

The arrangement remains subject to obtaining a final order from the Supreme Court of British Columbia approving the arrangement and the satisfaction of certain customary closing conditions. It is currently expected that the transaction will close on or about Aug. 13, 2025.

In accordance with the policies of the TSX Venture Exchange, Granite Creek also provides the following disclosure with respect to its previously announced non-interest-bearing bridge loan from Cascadia. Cascadia provided Granite Creek with the bridge loan in the principal amount of $375,000 to finance transaction expenses incurred in connection with the arrangement. The bridge loan is evidenced by two tranches of promissory notes issued by Granite Creek to Cascadia, consisting of: (i) a first tranche promissory note in the amount of $125,000 dated June 18, 2025; and (ii) a second tranche promissory note in the amount of $250,000 dated June 27, 2025. The bridge loan has a term of one year and includes a conversion right, whereby Cascadia may convert all or a portion of the outstanding principal amount into Granite Creek shares at a price per Granite Creek share of five cents. The Granite Creek shares underlying the promissory notes are subject to a hold period of four months and one day from the date of the issuance of each respective promissory note.
