The Casa Berardi mine is located 95 kilometres north of La Sarre, Quebec. On March 25, 2026, Orezone Gold Corporation completed its acquisition of Hecla Quebec Inc., a subsidiary of Hecla Mining Company, thereby acquiring a 100% interest in the Casa Berardi mine. The mine, which began commercial operations in 1988, operates as both an underground and open-pit mine. The lower-margin east mine underground operations were closed in July 2023, with underground mining since then focused on the higher-margin stopes of the west mine. Plans were revised to extend this underground mining throughout 2025. Since its opening, the mine has produced over 3.2 million ounces of gold. Orezone plans to integrate the Casa Berardi operations through 2026 and intends to publish an updated mine plan and economic study in the fourth quarter of 2026.

Production overview - 2023: gold 90363 oz, silver 22415 oz.

The Casa Berardi mill has a throughput of 1.4 million tonnes per annum. The metallurgical recovery rate for gold was 85% in 2023, 85% in 2024, and 87% in 2025.

Orezone has initiated studies to evaluate the optimisation of the current mine plan and a potential increase in underground production. The company also plans to start a multi-year exploration drill program of 80,000 to 100,000 metres annually, targeting high-grade extensions and near-mine mineralisation.

The San Juan Silver project is a high-impact development project located in the Creede Mining District, which is one of Colorado's most prolific silver districts.
