Nuvau Minerals Inc. (TSXV: NMC) has announced new assay results from its summer 2026 drill programme at the Thundermine property near Matagami, Québec, reporting 17.37 g/t gold over 2.40 metres in drill hole TH-26-11. The intersection sits approximately 50 metres shallower than drill hole TH-26-08, which previously returned 138.9 g/t gold over 4.4 metres, adding a new data point that the company says confirms mineralisation continuity. With six additional drill holes still awaiting assay results and the system remaining open, investors may be watching closely for further updates from this orogenic gold target.

Key Points

  • Nuvau Minerals Inc. (TSXV: NMC) released summer 2026 drill results from the Thundermine property, Matagami, Québec
  • Drill hole TH-26-11 returned 17.37 g/t Au over 2.40 metres within a broader 165-metre mineralised interval averaging 0.37 g/t Au
  • TH-26-11 is located approximately 50 metres shallower than TH-26-08, bridging the gap to historical drill holes and confirming system continuity
  • Six additional summer 2026 drill holes remain pending assay; the system is described as open along trend and at depth

TH-26-11 Drill Results and Mineralised Interval at Thundermine

Drill hole TH-26-11 intersected a 165-metre composite interval from 112.8 metres to 277.7 metres grading 0.37 g/t gold, hosting a higher-grade core of 17.37 g/t gold over 2.40 metres between 178.00 and 180.40 metres downhole. The release states that multiple sub-intervals within the broader composite exceeded 1 g/t gold, with individual half-metre samples reaching up to 39.83 g/t Au. The company notes that vein density and gold grade vary considerably within the tonalitic intrusive host, consistent with its interpretation of a structurally controlled orogenic system analogous to those found in the Val-d'Or camp.

Structural Significance: Bridging TH-26-08 and Historical Drill Holes

According to the announcement, TH-26-11 is positioned approximately 50 metres shallower than TH-26-08 and roughly midway between that hole and historical drill intercepts, providing an additional correlation point within the mineralised system. The company states that all summer 2026 drill holes analysed to date have returned gold mineralisation, and that the same altered tonalitic intrusive and quartz-tourmaline vein network has been identified consistently across the programme. The disclosure suggests the mineralised footprint at Thundermine is building a coherent structural picture that the company says supports significant vertical persistence.

Thundermine's 40-Year Exploration Gap and Open System

Nuvau notes in the release that the Thundermine property has not seen systematic exploration in more than 40 years. The company controls approximately 1,380 square kilometres of tenure within the Matagami mining district, which also hosts a zinc-copper VMS exploration target alongside the newly emerging gold potential. The system remains open along its interpreted southeast trend and at depth. Six drill holes from the summer 2026 programme are still pending laboratory results, meaning the dataset from this campaign is not yet complete.

Quality Assurance and Qualified Person Sign-Off

Assay work was conducted by MSALABS in Val-d'Or, Québec, an ISO/IEC 17025-accredited independent laboratory, using PhotonAssay™ technology on nominal 500-gram aliquots. The company's QA/QC programme included certified reference materials, blanks, and duplicates representing approximately 11 per cent of submitted samples. The scientific and technical content of the announcement was reviewed and approved by Bastien Fresia, Professional Geologist (Québec) and Qualified Person under National Instrument 43-101.
