Nuvau Winter Drilling at Thundermine Returns 5.28 g/t Au over 6.1 m, Including 7.22 g/t Au over 3.1 m

Nuvau Minerals Inc. (NMC) has released initial winter drilling results from the Thundermine target within its 100%-owned Matagami Mining Camp. The primary intercept, TH-26-04, returned 5.28 g/t Au over 6.10 m, including 7.22 g/t Au over 3.1 m. This zone is located approximately 200 metres below historical high-grade intercepts.

The company also intercepted a broad multi-zone gold envelope measuring 45.90 m @ 0.24 g/t Au. This result confirms VMS-style alteration and structurally controlled quartz-carbonate-fuchsite-sericite-chlorite veining. Historical validation is noted from drilling conducted in the 1950s and 1980s, which included an intercept of 1.0 m @ 78.16 g/t Au, although these historical data are not NI 43-101 compliant.

Winter drilling was suspended due to the spring thaw. A second drill rig is fully funded and scheduled to commence operations in early July to test structural extensions and optimize the gold system geometry.

This development follows a strategic progression for Nuvau Minerals Inc. After maiden gold discoveries at Bracemac in July and August 2025 and comprehensive base metal and gold updates in September 2025, the company secured the Matagami property from Glencore in March 2026. Subsequent actions included closing a $21.3M financing, appointing a new CEO, and launching a 17,500m drill program. The June 26 results represent the first material assay return from this newly funded campaign, aligning with the March exploration update.

Nuvau Minerals Inc. (NMC) released results from its Thundermine drill program, marking a routine positive follow-up to the March 2026 announcement. The findings align with previous expectations and the company’s stated objective of testing historical gold targets and expanding its district-scale gold model.

The company confirmed that the Pre-Feasibility Study (PEA) timeline remains targeted for Q4 2026, with no changes to its capital structure. A fully funded second rig has been secured to ensure continuity of the exploration program, thereby mitigating execution risk. While the news does not trigger an immediate financial impact or alter the near-term production restart strategy, it reinforces the geological thesis underpinning the upcoming PEA.

Nuvau Minerals Inc. (NMC) operates the 1,380 km² Matagami Mining Camp in northern Quebec, a Tier 1 jurisdiction located within the prolific Abitibi Greenstone Belt. The company’s flagship asset is the Bracemac-McLeod Mine, a fully permitted underground operation featuring developed infrastructure extending to 1,400 m depth and access to a 3,000 tpd concentrator.

Primary deposits include the Caber Complex, which contains 10.6 Mt at 2.35% CuEq, alongside the McLeod Extension, the Renaissance Deposit, and multiple gold targets such as Thundermine, the Bracemac footwall, and gold-in-till anomalies. Nuvau Minerals is pursuing a strategy of phased redevelopment to restart mining operations, leveraging existing infrastructure to reduce capital expenditures while expanding resources through district-scale exploration. Historical production at the site totaled 8.1 Mt at 6.1% Zn, 0.9% Cu, 24 g/t Ag, and 0.5 g/t Au.
