Orezone resumes operations at Casa Berardi; reaffirms 2026 production guidance

VANCOUVER, British Columbia, July 20, 2026 (GLOBE NEWSWIRE) -- Orezone Gold Corporation (TSX: ORE | ASX: ORE | OTCQX: ORZCF) (the “Company” or “Orezone”) is pleased to announce that operations resumed at its Casa Berardi mine in Quebec on the evening of July 17, following the voluntary suspension of operations announced on July 14 due to nearby wildfire activity.

During the temporary suspension, a skeleton workforce remained on site to preserve the operation while advancing planned maintenance activities originally scheduled for later in the year. As a result, the Company expects to benefit from reduced planned maintenance downtime over the balance of 2026.

The Company reaffirms its 2026 production guidance of 62,000 to 67,000 ounces from Casa Berardi. Orezone would like to thank SOPFEU (Société de protection des forêts contre le feu), our employees and contractors, and local authorities for their professionalism, dedication, and support throughout the voluntary suspension.
