Nuvau Intersects 138.87 g/t Gold over 4.45 m at Thundermine in Matagami

Nuvau Minerals Inc. (NMC) released initial summer assay results from the Thundermine target within its Matagami property in Quebec on September 9, 2026. The headline intercept came from hole TH-26-08, which returned 138.87 g/t Au over 4.45 metres downhole from 383.35 to 387.80 metres. This same hole included 0.85 metres at 629.15 g/t Au from 383.35 metres and 0.35 metres at 236.95 g/t Au from 387.45 metres.

Hole TH-26-05 returned a broad interval of 180.4 metres at 0.57 g/t Au from 102.30 to 282.70 metres, with a reported 2.70 metres at 10.52 g/t Au and five individual assays above 10 g/t Au. Hole TH-26-06 returned 81.9 metres at 0.24 g/t Au from 293.30 to 375.15 metres, including 1.50 metres at 9.29 g/t Au and 0.50 metres at 10.64 g/t Au.

All 10 summer holes intersected the targeted tonalitic intrusive, and visible gold was observed in seven holes. Assays for three holes have been received, while seven holes remain pending. The release states the system is open at depth and to the southeast, with drilling now tracing the geological framework for more than 300 metres along trend and more than 400 metres vertically.

• Hole TH-26-08: 138.87 g/t Au over 4.45 metres from 383.35 to 387.80 metres; 0.85 metres at 629.15 g/t Au from 383.35 metres; 0.35 metres at 236.95 g/t Au from 387.45 metres.
• Hole TH-26-05: 180.4 metres at 0.57 g/t Au from 102.30 to 282.70 metres; 2.70 metres at 10.52 g/t Au; five individual assays above 10 g/t Au.
• Hole TH-26-06: 81.9 metres at 0.24 g/t Au from 293.30 to 375.15 metres; 1.50 metres at 9.29 g/t Au; 0.50 metres at 10.64 g/t Au.

Nuvau Minerals Inc. (NMC) reported a new drill result, TH-26-08, which returned approximately 618 gm. This figure is roughly 19 times the gram-metres of the prior anchor result, TH-26-04, which returned 5.28 g/t Au over 6.10 metres, or about 32 gm, published on June 26, 2026. The new result is materially stronger in grade and contained gold, even after accounting for the narrow high-grade vein structure.

The stock did not re-rate upward on the prior result. It was around C$0.70 on June 25-26 and then fell, eventually trading near C$0.47-0.54 through July and August. Because the prior anchor was not embedded in the share price, this release is an unpriced positive rather than an in-line confirmation.

The company is a junior developer with a C$47 million market capitalization and no operating cash flow, so a high-grade gold discovery is capable of moving the equity.

Nuvau Minerals Inc. is a Canadian mining and exploration company listed on the TSX Venture Exchange under the ticker NMC. Its primary asset is the Matagami mining district in northern Quebec, a historic zinc-copper-silver-gold camp. The company controls roughly 1,380 square kilometres and has access to permitted infrastructure, including an option on a 3,000 tonne-per-day concentrator.

The company’s investment presentation details Caber Complex measured and indicated resources of 3.36 million tonnes at 5.18% Zn, 1.10% Cu, 14.30 g/t Ag and 0.16 g/t Au, with additional inferred resources. Historical production at Matagami totalled about 8.1 million tonnes at 6.1% Zn, 0.9% Cu, 24 g/t Ag and 0.5 g/t Au. A July 2023 preliminary economic assessment (PEA) showed an after-tax net present value (NPV) of about C$115.9 million at an 8% discount, though the presentation estimates a much higher spot-price NPV; these are prior-period economics and not part of today’s release.
