WESDOME ANNOUNCES SECOND QUARTER 2025 PRODUCTION RESULTS; ON TRACK TO ACHIEVE FULL-YEAR CONSOLIDATED PRODUCTION GUIDANCE

Wesdome Gold Mines Ltd. has released its production results for the three and six months ended June 30, 2025. The company is also providing notice that it will release its Q2 2025 financial results after markets close on Wednesday, Aug. 13, 2025, and host a conference call and webcast the following morning.

Anthea Bath, president and chief executive officer of Wesdome, commented: "We delivered a solid second quarter supported by safe and disciplined execution at both operations, keeping us on track to achieve our full-year consolidated production guidance with Eagle River's production trending to the high end of its guidance range and Kiena pacing at or slightly below the low end. As outlined in our 2025 outlook earlier this year, production remains weighted toward the second half, with the fourth quarter expected to contribute nearly one-third of total annual output.

"At Eagle River, stronger grades and improved productivity drove a meaningful increase in production, helped by reduced long-hole stope dilution. A planned two-week shutdown in May was completed safely, and maintenance carried out during this time is now enhancing mill performance.

"At Kiena, production was slightly ahead of the first quarter despite continued equipment availability constraints that limited access to planned stopes. Improved mobile fleet availability through enhancements to maintenance practices, and recent changes to site leadership point to a stronger second half. With one mining front currently in production, improving discipline in the planned mining sequence and priority development will be essential to support long-term performance. The addition of two new horizons, levels 136 and Presqu'ile, are expected to provide increased flexibility over the coming year.

"It was also a strategically important quarter for Wesdome. We closed the acquisition of Angus Gold, expanding our footprint in Ontario and strengthened our balance sheet by upsizing our credit facility to $300-million (U.S.), including a $50-million (U.S.) accordion feature. These initiatives reflect our disciplined approach and demonstrate our ability to act on opportunities that align with our growth strategy and support continued investment in our asset base."
