Orezone Reports First Quarter 2026 Gold Production

All dollar amounts are in USD unless otherwise indicated and abbreviation "M" means millions

Orezone Gold Corporation (TSX: ORE,OTC:ORZCF | ASX: ORE | OTCQX: ORZCF) (the "Company" or "Orezone") is pleased to announce its operating results for the three months ended March 31, 2026.

Patrick Downey, President and CEO, commented "The first quarter of 2026 included several important milestones for the Company. In late March, the Company closed its acquisition of Hecla Quebec, which included the operating Casa Berardi gold mine and a portfolio of exploration properties, all located in Quebec. With this transaction, Orezone is now a multi-asset diversified producer with an established and self-funded growth profile.

At Bomboré, the Company achieved commercial production of the 2.5Mtpa stage 1 hard rock expansion on January 16^th, which was accomplished in just over a month from the announcement of first gold. This achievement is a testament to the hard work and dedication of the operating team at Bomboré. During the quarter, mine sequencing was affected by intermittent deliveries of emulsion for planned hard rock blasting, resulting in lower than planned grades to the hard rock mill. Despite this, the mill performed extremely well and overall production costs trended in line for the quarter. Deliveries of emulsion have steadily improved, with gold production from the hard rock plant increasing month over month, with production weighted towards H2-2026 as originally guided."

PRODUCTION RESULTS

OPERATIONS COMMENTARY

Bomboré Operations

Mining rates in the first quarter were in line with budget. However, intermittent deliveries of emulsion for blasting necessitated an adjustment to the hard rock mining sequence which resulted in lower tonnes of high-grade hard rock ore being mined and processed in the quarter. The Company has since secured a second emulsion supplier which is expected to support more consistent deliveries. Orezone reiterates its 2026 Bomboré production guidance of 160,000 to 180,000 ounces.

Following the announcement of first gold on December 15, 2025, the 2.5Mtpa stage 1 hard rock plant achieved commercial production on January 16, 2026, with throughput exceeding nameplate design by 10% during the quarter.

All major components of the stage 2A hard rock expansion have now been procured and earthworks initiated. The stage 2A expansion consisting of a rock breaker, thickener and oxygen plant is expected to be completed in late Q3-2026 and will serve to incrementally improve recoveries and throughput.

Casa Berardi Operations

The Company closed its acquisition of Hecla Quebec on March 25, 2026. Following a scheduled shutdown for mill maintenance, five days of gold production from Casa Berardi were attributable to Orezone in the first quarter.

At quarter end, Orezone entered into an agreement with an underground mining contractor, which is now in the process of mobilizing to site. The contractor will be utilized to ramp-up development rates in support of increasing underground production as well as to establish exploration platforms for planned drilling in 2026 and 2027.

Surface and underground exploration drilling are underway with three drills, with an additional two drills to be added within the next month.

The Company plans to provide 2026 post-acquisition guidance for Casa Berardi in the second quarter.
