OREZONE REPORTS Q2 2026 PRODUCTION AND PROVIDES CASA BERARDI OPERATIONS UPDATE

Orezone Gold Corp. has released its production results for the three and six months ended June 30, 2026. The company expects to release its second quarter 2026 financial results after market close on Wednesday, Aug. 12, 2026. Conference call and webcast details are provided at the end of this release.

Patrick Downey, president and chief executive officer, commented: "The second quarter marked Orezone's first full quarter as a multimine producer following the acquisition of Casa Berardi, with both operations performing in line with our expectations. At Casa Berardi, we continued investing in underground development, exploration and equipment to support higher underground throughput and production over time, leveraging the established resource base and infrastructure already in place. As outlined in our 2026 guidance, Bombore is expected to deliver a stronger second half of the year as access to higher-grade hard rock ore continues to improve, while Casa Berardi's production profile reflects planned mine sequencing, with a lower expected third quarter before strengthening in the fourth quarter."

Bombore operations

During the second quarter, Bombore delivered strong mining performance, with total tonnes and ore tonnes mined exceeding plan. Following the intermittent explosives supply experienced during the first quarter, mining activities advanced in line with the revised mining sequence with additional contractors and drilling capacity mobilized, providing improved access to higher-grade hard rock ore in the last half of the year. As previously guided, production is expected to be weighted toward the second half of 2026, with the fourth quarter anticipated to be the strongest as ore deliveries from the higher-grade P17 pit increase.

Processing performance remained strong in the quarter, with both the oxide and hard rock circuits continuing to achieve throughput rates above nameplate design while maintaining recoveries in line with expectations.

Casa Berardi operations

During the second quarter, Casa Berardi invested in underground development through additional mine development, expanded definition drilling, and the mobilization of new equipment and labour in support of higher underground throughput and production in future quarters.

Open pit mining at F160 continued through the quarter. The current pit schedule is for higher-grade direct feed ore to increase during the fourth quarter with third quarter mill feed supplemented by existing lower-grade stockpiles, in line with guidance.

Processing performance remained strong throughout the quarter, with continuing mill improvements contributing to average throughput of just over 4,000 tonnes per day, exceeding the planned rate of 3,900 tonnes per day.

The operation also continued advancing several strategic initiatives, including completion of the expanded F134 and F160 pit designs, advancement of the life-of-mine study, and increased exploration activities to support future mine planning and underground production growth.

Casa Berardi operations update -- local wildfire

On July 10, a wildfire commenced approximately 12 kilometres to the southwest of the Casa Berardi mine. As a precautionary measure, the company voluntarily suspended operations which remains in effect. With favourable weather conditions over the last 48 hours and the continuing wildfire suppression efforts by SOPFEU (Societe de protection des forets contre le feu), the company anticipates lifting the voluntary suspension in the coming days.

Orezone does not expect that the temporary suspension in operations will impact its 2026 production guidance for Casa Berardi.
