Doré Copper Acquires Majority Stake in Claims Near Corner Bay Project

Doré Copper Mining has entered into an agreement with SOQUEM to acquire a 56.41% interest in a group of contiguous claims located immediately north and east of its flagship high-grade Corner Bay copper project in the Chibougamau mining camp, about 55 kilometers by road from Chibougamau, Québec.

The Claim Group consists of 17 claims covering an area of 446 hectares within Doré Copper's 100%-owned Corner Bay-Devlin Property, which spans 5,446 hectares. Historical exploration in the 1970s included 36 diamond drill holes totaling approximately 7,610 meters, while further activities from 1992 to 1998 by SOQUEM added another 28 diamond drill holes totaling 5,327 meters.

Several parallel shear zones trending northwest-southeast were identified over a 1.4-kilometer strike length. These mineralized zones, characterized by narrow quartz and calcite veins containing between 10% and 40% chalcopyrite and pyrite, have been tested to a vertical depth of 400 meters. Significant historical drill intercepts on the Claim Group include:

• 13.15% Cu over 0.61 meters
• 5.45% Cu over 2.40 meters, including 13.9% Cu over 0.80 meters
• 8.92% Cu over 0.91 meters
• 12.45% Cu over 0.43 meters
• 15.26% Cu over 0.76 meters
• 9.8% Cu over 1.25 meters
• 12.37% Cu over 0.91 meters

The potential northern strike extension of the Corner Bay deposit, which has not been tested on the Claim Group, could provide an additional 800 meters along strike for exploration. Additionally, the intersection area between the north-south Corner Bay shear zone and the northwest-southeast shear zones of the Claim Group presents another target of interest.

Ernest Mast, President and CEO of Doré Copper, stated, "The acquisition of SOQUEM's Claim Group further consolidates the land position around our flagship Corner Bay copper deposit. High-grade copper shear zones, with similar mineralization to the Corner Bay deposit, have already been identified on the Claim Group. We plan to review and incorporate all the available data into our geological model to better define the areas which have not been adequately followed for future exploration plans."

SOQUEM will receive a cash payment of $20,000 and the equivalent of $125,000 in common shares of Doré Copper upon execution of the agreement. If a mineral resource estimate in accordance with NI 43-101 is completed on the Claim Group, Doré Copper will pay SOQUEM $100,000. Upon commencement of commercial production, defined as greater than 200 tonnes per day for seven consecutive days, Doré Copper will pay SOQUEM $250,000 and a 1% Net Smelter Return royalty (NSR) on the production of copper and gold. Doré Copper has the option to purchase 50% of the NSR for $500,000 and the remaining 50% for $1,000,000 at any time prior to commercial production. The agreement is subject to approval by the TSX Venture Exchange.
