Nuvau Provides Comprehensive Exploration Update at Matagami

Executive Summary

• Nuvau Minerals announced multiple high‑grade base‑metal intercepts and the first significant gold discovery (8.87 g/t Au over 1.05 m) at its Bracemac orogenic gold system on the Matagami Project.
• Ongoing drilling across Caber Complex, Renaissance Zone, and McLeod Extension generated several notable copper‑zinc‑gold‑silver intersections, supporting pending updates to Mineral Resource Estimates (MREs) and a forthcoming Pre‑Feasibility Study (PEA).
• The company highlighted forward‑looking plans to incorporate the new gold system into future economic studies and potential restart of the permitted Bracemac‑McLeod mine.

Key Details

• McLeod Extension – 5,526 m drilled

• Discovery hole MCL‑13‑31W1 (2023): 15.9 m grading 2.81 % Cu, 14.80 % Zn, 0.39 g/t Au.

• New intersections: 0.52 % Cu, 10.96 % Zn, 0.42 g/t Au, 11.71 g/t Ag over 4.20 m; 2.45 % Cu, 0.24 % Zn, 0.11 g/t Au, 11.39 g/t Ag over 7.75 m.

• Resource & Study Updates

• Caber Complex: drilling aimed at resource conversion and metallurgical sampling for a future Feasibility Study; revised MRE in progress.
• Renaissance Zone: initial MRE underway.

• McLeod Extension: results to be incorporated into an updated MRE and considered in restart economics for Bracemac‑McLeod mine.

• Forward‑Looking Plans

• Continue gold‑focused drilling on the newly identified shear zone (four holes spaced 25–40 m, a fifth hole targeting 100 m depth).
• Integrate gold system into upcoming PEA and economic analyses for potential mine restart.

Notable Quotes

“Multiple new discoveries, including the recent discovery of gold mineralization, demonstrate the potential of this large‑scale property that was historically recognized solely for its base metal potential.” – Peter van Alphen, President & CEO, Nuvau Minerals Inc.
