Wesdome Defines 10 Kilometres of Prospective Strike and Expands Near-Surface Mineralization at Eagle River

The most recent news, dated December 15, 2025, provides a surface exploration update for the Eagle River Mine in Ontario. The key highlights include: - A new interpretation at the Mishi and Magnacon zones has opened up a 10-kilometre potential strike length along the Mishibishu Deformation Zone. - The company completed 9,600 metres of drilling at Mishi, 14,000 m at Dorset, 8,400 m at the Falcon Zone, and 4,300 m at the Cameron Lake Iron Formation. - Drilling at the Mishi Shear Zone returned intercepts such as 4.7 metres of 8.3 g/t Au and 2.5 metres of 6.4 g/t Au. - Drilling at the Falcon 720 Zone returned 5.4 metres of 10.0 g/t Au. - Results from the Dorset Zone and Cameron Lake Iron Formation showed broader, lower-grade mineralization, such as 88.6 metres of 1.0 g/t Au. - Management stated that systematic groundwork is paying off and they are building momentum for an expanded regional exploration program in 2026.

The December 15th exploration update is positive, demonstrating continued progress in defining the large-scale potential of the consolidated Eagle River land package, which was significantly expanded through the acquisition of Angus Gold in mid-2025. The identification of a 10-kilometre prospective trend is significant for the long-term outlook and supports the company's "fill-the-mill" strategy. The drill results, while not spectacular, are solid and confirm the presence of gold in multiple geological settings.

However, this news is routine in nature and does not address the market's primary concern: the persistent operational failures at the Kiena Mine in Quebec. A review of the news flow reveals a stark contrast between the two assets.

• Eagle River: Has consistently over-delivered, leading to an increase in its 2025 production guidance in August. Exploration success, as detailed in the September 3 and December 15 releases, continues to underscore its value as a high-quality, long-life asset.
• Kiena: Has been a major source of disappointment, with two significant downward revisions to its 2025 production guidance.
  • August 13: Guidance was cut from 90-100k oz to 80-90k oz due to equipment constraints and stope underperformance.
  • November 4: Guidance was cut again to 72-78k oz, with the company citing "contractor execution challenges and underperformances at Presqu'ile."

These repeated operational misses at Kiena have materially damaged management's credibility in forecasting and execution. The Q3 earnings call on November 5 confirmed these issues, with management pointing to underperformance by development contractors and the need to bring more functions in-house. A key risk highlighted on the call is a potential delay in receiving the full mining permit for the Presqu'ile zone, which could impact Q1 2026 production if the bulk sample permit is exhausted.

Therefore, while the latest exploration news from Eagle River is encouraging for the long-term picture, it is overshadowed by the near-term execution risk at Kiena. The market will remain skeptical and focused on Kiena's performance until management can deliver a clean quarter and meet its revised targets. The positive exploration news is unlikely to materially rerate the stock until the operational issues are demonstrably resolved.

Wesdome Gold Mines Ltd. is a Canadian-focused gold producer operating two high-grade underground mines. 1. Eagle River Complex (Ontario): This is the company's flagship and most reliable asset. It has been in continuous production for over 30 years. The complex includes the Eagle River underground mine and the Mishi open pit, with all ore processed at a central mill. The operation is performing exceptionally well and is the primary driver of the company's strong financial results. 2. Kiena Mine Complex (Quebec): This is a past-producing mine that was restarted in 2021. It is centered around the high-grade Kiena Deep A Zone. While it has significant growth potential, the asset has been plagued by ramp-up issues, operational challenges, and contractor underperformance throughout 2025, leading to two guidance cuts.

The company's strategy is focused on a "fill-the-mill" approach at both sites, leveraging existing infrastructure to process ore from satellite deposits and newly discovered zones.
