Canada Considers National Interest Status to Support Zinc, Copper and Silver Development

Nuvau Minerals announced encouraging results from its 2026 winter drilling program at the Thundermine target in Quebec’s historic Matagami mining camp. Drill hole TM-26-001 intersected 6.10 meters grading 5.28 g/t gold, including a higher-grade interval of 3.10 meters grading 7.22 g/t gold. Drill hole TM-26-004 also returned 2.50 meters grading 3.15 g/t gold. The Matagami camp has historically been known for large-scale base metals production, having produced more than 10 billion pounds of zinc and nearly 1 billion pounds of copper since the 1960s. The latest Thundermine results suggest that, beyond its traditional VMS-style copper-zinc mineralization, the district may also host significant orogenic gold potential. Nuvau said a follow-up drilling campaign is scheduled to begin in July 2026, focusing on step-out drilling along strike and down dip from the TM-26-001 intercept to test the continuity and resource growth potential of the high-grade gold zone.

Blue Lagoon Resources announced that its Dome Mountain gold-silver mine in British Columbia, Canada, has achieved commercial production and is ramping up throughput from over 100 tonnes per day toward a target rate of 150 tonnes per day. The company expects to produce approximately 15,000 oz of gold over the next 12 months, with annual output potentially increasing to 20,000 oz thereafter. Dome Mountain is a quartz-carbonate vein-hosted gold-silver deposit that also contains lead, zinc and copper credits within its concentrate. Blue Lagoon stated that its next major focus will be exploration, with drilling programs scheduled to resume later this year. The company aims to expand the Boulder vein resource through infill, strike-extension and deep drilling, targeting a long-term resource inventory of 1 million ounces of gold. Current resources at the Boulder vein stand at approximately 234,000 oz of gold, while mineralization remains open along strike and at depth, providing significant resource growth potential.

Appian Capital Advisory, which holds a 90% stake in Namibia’s Rosh Pinah zinc-lead mine, announced the successful commissioning of a new SAG (semi-autogenous grinding) mill, marking the completion of the final major processing component of the RP2.0 expansion project. The new SAG mill replaces the existing ball mill and is expected to double the mine’s processing throughput from approximately 700,000 tonnes of ore per year to 1.4 million tonnes annually following ramp-up. The upgraded facility will also improve the plant’s ability to process harder ore types as mining advances deeper underground. With the SAG mill now operational, the entire RP2.0 circuit—including the new zinc flotation circuit, paste fill plant, water treatment facility, and expanded thickening and filtration systems—has been fully integrated. Appian stated that overall project construction progress has exceeded 95%, and the expansion is expected to extend mine life, improve resource utilization, and support higher zinc concentrate output in the coming years.
