WESDOME ANNOUNCES FIRST QUARTER 2025 PRODUCTION; PROVIDES TIMING OF FIRST QUARTER FINANCIAL RESULTS AND WEBCAST

Wesdome Gold Mines Ltd. has released its production results for the first quarter ended March 31, 2025. The company is also providing notice that it will release its Q1 2025 financial results after market close on Tuesday, May 13, 2025, and host a conference call and webcast on May 14, 2025.

Anthea Bath, president and chief executive officer of Wesdome, commented: "We are pleased to report that total gold production for the first quarter exceeded our expectations, and we remain on track to meet our full-year production guidance. As previously outlined, we expect a second-half-weighted production profile with the fourth quarter projected to account for approximately 30 per cent, and all-in sustaining costs per ounce in the first half of the year to be approximately 15 per cent above full-year guidance, reflecting the timing of production and sustaining capital expenditures.

"Eagle River had a strong start to the year, driven by higher-than-anticipated average head grade from the 300 zone. The operations team continues to execute well against the planned mining sequence, benefiting from positive grade reconciliation and the processing of ore stockpiled in late 2024. We continue to expect Eagle River to produce between 100,000 and 110,000 ounces of gold in 2025.

"Kiena's production in the first quarter nearly doubled compared to the same period last year, reflecting the ongoing ramp-up of high-grade feed from the Kiena Deep zone that commenced in April, 2024. Underground mining activities in select areas of the south and north limbs as well as Kiena Deep A2 zone are transitioning from a primarily long-hole mining method to a hybrid approach, combining cut-and-fill and long-hole stoping. We are steadily ramping up this new approach, which is already delivering encouraging results early in the second quarter and helping to drive more predictable performance.

"With a strong first quarter, we are well positioned to achieve our operational targets for the remainder of the year."
