Nuvau Launches 17,500-Metre Drill Program at Matagami

Exploration to target VMS-hosted polymetallic copper-zinc mineralization and gold potential on this district-scale property

Drills have mobilized at Nuvau Minerals Inc.'s (TSXV: NMC,OTC:NMCPF) flagship Matagami Property now that the Company's $21M financing has closed. The overall goal of Nuvau's fully-funded 2026 campaign is to work toward realizing the critical minerals and gold potential of this 1,380 km2 district-scale land package.

"With this launch, we have achieved our third significant corporate milestone in as many months," said Peter van Alphen, Nuvau's CEO. "After closing the financing and the earn-in on the Matagami Property, we are now focused on extending Nuvau's track record of discovery to grow our resource base while advancing our near-term production strategy."

A program with two objectives: adding to copper-rich resources through continued exploration for base metals mineralization and unlocking gold potential.

Approximately 17,500 metres will be drilled across eight prospective sectors on the property, where copper-rich volcanic massive sulphides (VMS) and gold occurrences occur in close proximity. Drilling will initially focus on three target areas: Thundermine, the Daniel 25 area, and the North Central camp.

The program's two primary objectives reflect this unique geological setting:

• Testing VMS-hosted copper targets - Drilling will test targets associated with VMS-hosted critical metal mineralization that have been defined using integrated geophysical surveys, geochemical data, and till anomalies. The goal is to expand Nuvau's resource base, and support advanced engineering studies aimed at near-term production at Matagami

• Unlocking gold exploration potential - Drilling to develop a gold exploration model for the property, building on Nuvau's first gold occurrence discoveries in 2025. The Matagami district occupies a strategic geological position between two major gold-bearing deformation corridors: the Sunday Lake Deformation Zone to the north, host to the Detour Lake Mine, and the Casa Berardi Deformation Zone to the south, host to the Casa Berardi, Joutel, and Vezza deposits.

Nuvau is collaborating with its drilling contractor to extend the drilling season and enable year-round exploration. In a camp like Matagami, which presents logistical challenges due to the extensive wetlands and swamp terrain, drilling is typically restricted to winter conditions. New operational approaches, such as using lightweight drilling rigs and wooden matting, are planned to be implemented during this campaign. Advanced ground preparation during the winter will also minimize environmental disturbance and reduce remediation requirements during the spring thaw.
