Wesdome Intersects New Zone at Kiena's Dubuisson Deposit
None
On October 27, 2025, Wesdome Gold Mines announced the discovery of a new mineralized zone at the Dubuisson deposit, part of the Kiena Mine Complex in Quebec. The discovery was made during a 41-hole, 11,361-metre drill program. The key highlight was drill hole DB-25-068, which intersected 25.8 metres of 4.1 g/t gold (Au). This new zone is located approximately 100 metres below and lateral to the known Dubuisson North Zone and is within 350 metres of existing underground infrastructure (Level 33 exploration drift).
This exploration news is materially positive. It follows a series of strong corporate and operational updates, including record Q3 2025 production, the announcement of a Normal Course Issuer Bid (NCIB), and the appointment of a highly experienced new CFO.
The discovery's significance lies in several key areas: 1. Reinforces the Kiena "Fill-the-Mill" Strategy: After a mixed Q2 2025 report where Kiena's production guidance was lowered due to operational challenges, consistent exploration success is critical to rebuilding confidence in the asset's long-term potential. This discovery of a new zone, rather than just an extension, adds a potential new source of ore to the mine plan. 2. Favorable Economics: The intercept's characteristics—a wide 25.8-metre interval with a decent grade of 4.1 g/t Au—suggest potential for bulk mining methods. Crucially, its proximity (350 metres) to existing underground development drastically reduces the potential capital cost and timeline to bring it into production, significantly improving its economic viability. 3. Demonstrates Exploration Upside: The discovery validates management's exploration strategy and highlights the untapped potential of the Kiena land package beyond the well-known Kiena Deep zones. The Dubuisson satellite deposit now appears more significant than its current resource estimate implies.
This news, viewed in the context of the strong Q3 operational rebound (over 50,000 oz produced) and the company's robust financial health ($266M cash, no debt), provides further evidence that Wesdome is successfully executing on its organic growth strategy. While a single drill hole does not define an orebody, it is a very strong start and a clear positive catalyst.
Wesdome Gold Mines is a Canadian gold producer focused on high-grade underground mining. The company operates two flagship assets: 1. Eagle River Complex: Located in Wawa, Ontario. It has been in continuous production since 1995. The company recently acquired Angus Gold Inc. in June 2025, quadrupling the land package around Eagle River to create a district-scale opportunity. 2. Kiena Complex: A past-producing mine located in Val-d'Or, Quebec, which was restarted in 2021. The current focus is on mining the high-grade Kiena Deep A Zone and exploring satellite deposits like Presqu'île and Dubuisson to utilize the full capacity of its 2,040 tpd mill.
The company's overarching strategy is "fill-the-mill" through organic growth, driven by aggressive exploration programs at both sites to expand resources and extend mine life.
