WESDOME FILES UPDATED TECHNICAL REPORTS

FOR EAGLE RIVER AND KIENA MINES; ESTABLISHES LONG LIFE RESERVE PLANS

WITH SUBSTANTIAL UPSIDE POTENTIAL

Toronto, Ontario – August 6, 2026 – Wesdome Gold Mines Ltd. (TSX:WDO , OTCQX:WDOFF) (“Wesdome” or the

“Company”) today announced that it has filed independent technical reports (the " Technical Reports ") prepared in

accordance with National Instrument 43-101 – Standards for Disclosure for Mineral Projects ("NI 43-101") for its Eagle

River Mine ("Eagle River") in Ontario and its Kiena Mine ("Kiena") in Québec.

The Technical Reports entitled “Independent Technical Report for the Eagle River Mine, Ontario, Canada ” and “NI 43-

101 Technical Report and Feasibility Study for the Kiena Mine Complex , Val-d’Or, Québec, Canada” support and are

consistent in all material respects with the updated mineral reserve and mineral resource estimates and additional

disclosure in the Company's news release "Wesdome Extends Reserve Life to 8 Years at Both Mines, Establishes

Robust Free Cash Flow Profile, and Outlines Significant Organic Growth Pipeline ”, dated June 24, 2026.

Anthea Bath, President and Chief Executive Officer, stated: “The Technical Reports filed today provide independent

validation of the significant work our team has undertaken over the past several years to strengthen the foundation of

Wesdome. They establish the most robust reserve -based mine plans in the Company’s history, with both Eagle River

and Kiena now supported by eight -year operating plans that provide a resilient platform for disciplined execution and

sustainable growth.

“Importantly, at Kiena, we see a pathway to increasing annual production by approximately 10 –15% through additional

mining fronts, productivity improvements and continued technical optimization, while advancing Kiena East as a potential

future mining centre with meaningful scale. At Eagle River, our priority remains to maximize the value of our high -grade

underground operation while continuing to extend mine life and test the broader mineral system. Beyond Eagle River’s

underground mine, Mishi-Magnacon has the potential to support an open pit operation, and we expect to evaluate this

opportunity through a conceptual study over the next 12 to 18 months.

“Across both land packages, the Technical Reports define a substantial pipeline of exploration opportunities, ranging

from near-mine extensions to large-scale targets. We believe these opportunities demonstrate that Wesdome is evolving

beyond individual mines into two emerging mining districts, each with multiple pathways to extend mine life, enhance

infrastructure utilization and create long-term shareholder value.

“Wesdome is well positioned to capitalize on tangible opportunities to scale production and extend mine life. Our focus

remains on converting that potential into per -share value through disciplined execution and continued technical

advancement, while delivering returns to shareholders.”

The Technical Reports are available under the Company's profile on SEDAR+ at www.sedarplus.ca and on the
