Nuvau Minerals has intersected 138.87 grams per tonne gold over 4.45 metres, including 629.15 grams per tonne gold over 0.85 metres, from initial summer drilling at the Thundermine target within its Matagami Mining District Property in Québec.

Drillhole TH-26-08 yielded the high-grade intercept from quartz-tourmaline veins within a broader intrusive-hosted mineralized system. A second hole, TH-26-05, intersected a wider interval of 180.4 metres averaging 0.57 grams per tonne gold, containing multiple mineralized veins including 10.52 grams per tonne gold over 2.70 metres alongside five individual intervals exceeding 10 grams per tonne. All ten summer drillholes intersected the targeted tonalitic intrusive and associated hydrothermal system, with visible gold observed in seven holes.

“These initial assay results from Thundermine, together with the geological data accumulated from 10 holes of drilling, are very encouraging and have established this as a highly prospective gold target. These are the first assays from our summer drill program,” said Christina McCarthy, Nuvau's Chief Executive Officer. “We have intersected high-grade gold veins within a much broader disseminated intrusive and are seeing the same setting continue as we step away from the limited area that was drilled historically.”

“The similarities to the quartz-tourmaline gold systems with the large-scale gold deposits in the Sigma-Lamaque district in Val-d'Or provide a compelling geological model to follow, and Thundermine remains open at depth and along strike. With seven holes still pending and only a small part of the larger prospective trend tested, we are just getting started.”

Assays from seven summer drillholes remain pending. Nuvau acquired a 100% interest in the Matagami property from Glencore Canada Corporation in March 2026. The company subsequently commenced a preliminary economic assessment study in June 2026 to evaluate the potential restart of the Bracemac-McLeod Mine.

Following the current analytical work, Nuvau Minerals plans subsequent step-out drilling along trend and at depth at the Thundermine target.
