Orezone hits positive drill results at Bomboré ahead of Q1 2027 resource update

Orezone Reports Positive Drill Results at Bomboré Demonstrating Growth Potential Ahead of Mineral Resource and Reserve Update in Q1 2027

VANCOUVER, British Columbia, Aug. 11, 2026 (GLOBE NEWSWIRE) -- Orezone Gold Corporation (TSX: ORE | ASX: ORE | OTCQX: ORZCF) (the “Company” or “Orezone”) is pleased to provide additional drill results from its Bomboré Gold Mine.

Patrick Downey, President and CEO, commented “These latest exploration drill results continue to demonstrate the growth potential at Bomboré, confirming the continuity of gold mineralization beyond the current Mineral Resources and Mineral Reserves.

Step-out drilling continues to highlight significant exploration upside along strike, demonstrated by follow-up drilling at P16, that confirmed the zone’s 600 metre strike extension and its overall sub-parallel orientation to the P17 high-grade trend. As with P17, the emerging P16 trend hosts notably higher-grade zones within a broader envelope of lower grade mineralization. Ongoing structural studies and future exploration drilling will focus on refining the controls and continuity of these higher-grade zones, which are potentially amenable to underground mining and could significantly enhance the production profile.

In addition to our successful expansion drilling programs, the 2026 resource definition program focused on converting Inferred Resource to the Indicated category, supporting a Mineral Resource and Mineral Reserve update which is expected to be released in the first quarter of 2027. The updated estimate will incorporate the results of approximately 100,000m of additional drilling, in addition to an adjusted cut-off grade reflective of current operating costs and higher gold prices. Given Orezone’s ongoing exploration success in extending mineralization to depth and along strike, we expect that t
