XXIX Metal Corp. Advances Cooke Drill Program with Visible Gold

XXIX Metal Corp. has made significant progress in its drilling program at the Cooke Gold Zone, located in Ontario, Canada, with promising results that include visible gold and extensive copper intervals. The company reported on November 24, 2025, that it has completed six of the planned 23 drill holes, revealing copper-bearing intervals ranging from 12 to 48 metres in core length. Notably, visible gold was observed in two of these holes, indicating potential for open-pit development.

The drill program targets the crown pillar of the historical Cooke Gold Mine, which is expected to enhance the economic outlook in the forthcoming Pre-Feasibility Study. This initiative is part of a broader strategy aimed at increasing resources at the Opemiska site, where only 55% of the current mineral resource estimate has been factored into the Preliminary Economic Assessment released in June 2025.

Exploration Highlights and Future Potential

The ongoing exploration efforts also focus on the Saddle Zone, a critical area within the planned open pit that has not yet been incorporated into the existing mineral resource estimates. Historical drilling in this zone has indicated high-grade copper mineralization, with notable results including 5.29% copper and 1.20 g/t gold over 11.0 metres. Additional drilling is necessary to fully evaluate this area before it can be included in future resource estimates.

Furthermore, XXIX plans to investigate mineralization below the proposed open pit as a potential underground resource. The Springer and Perry zones within the Opemiska project have demonstrated mineralization extending to depths nearing one kilometre. The company expressed confidence in the likelihood of substantial underground resources that could be integrated into future development plans.

XXIX has mobilized a second drill rig to expedite the program in light of the encouraging results obtained thus far. This expansion will allow the company to target additional high-priority exploration areas.

Previous Assessments and Current Operations

The Cooke Gold Zone has a rich historical background, having produced approximately 1.97 million tonnes with an average grade of 5.04 g/t gold and 0.66% copper. This history positions the current drilling program as a strategic move to tap into underexplored potential.

The Chibougamau Copper Zone, located just north of Cooke, has also shown promise, with seven drill holes completed to date, all intersecting copper mineralization. This area represents additional upside for the company’s copper resources, complementing the existing estimates established in the October 2025 Preliminary Economic Assessment.

XXIX Metal Corp. remains committed to advancing its Opemiska and Thierry Copper projects, both significant Canadian copper assets. The Opemiska Project is recognized as one of Canada’s highest-grade open-pitable copper deposits, spanning 21,333 hectares in Quebec’s Chapais-Chibougamau region. A recent Preliminary Economic Assessment outlined a proposed operation with a 17-year mine life, projecting an after-tax NPV of $505 million and an internal rate of return of 27.2%.

As XXIX Metal Corp. continues to explore and develop its assets, the company reinforces its position as a key player in the Canadian copper sector, with a focus on resource expansion and economic viability.
