Wesdome Provides Comprehensive Eagle River Exploration Update; High Grade 6 Central Zone Extended by 300 Metres with Intercepts Including 115.9 g/t Gold (Cut) Over 1.6 Metres (True Width)

Executive Summary

• Wesdome reports a series of high‑grade underground drill intercepts across multiple zones at Eagle River, notably 115.9 g/t Au over 1.8 m in the 6 Central Zone and several >30 g/t Au hits in the Falcon and Dorset areas.
• The 6 Central Zone has been extended down‑plunge by ~300 m to a total of >600 m, remaining open laterally and at depth, supporting potential future resource conversion.
• A nine‑month global model drilling program (≈40,000 m) is underway, with results slated for incorporation into an updated technical report in mid‑2026; overall drilling to date in 2025 totals ~80,000 m at Eagle River.

Key Details

• 6 Central Zone
• Hole 758‑E‑580: 115.9 g/t Au (uncapped) over 1.8 m core length (true width 1.6 m).
• Hole 758‑E‑570: 49.1 g/t Au over 2.2 m (true width 2.0 m).
• Hole 25‑805‑12: 47.0 g/t Au over 3.4 m (true width 3.2 m).

• Total drilling in zone to date ≈18,000 m across 65 holes; zone extended ~300 m down‑dip.

• 300 & 300 Fold Zones

• Hole 1201‑E‑87: 18.5 g/t Au over 1.5 m (true width 0.8 m).

• Hole 1224‑E‑04: 23.8 g/t Au over 2.3 m (true width 1.7 m, cut to 17.5 g/t).

• Falcon Zones

• Falcon 720 – Hole 25‑355‑07: 32.6 g/t Au over 1.8 m (true width 1.7 m).

• Falcon 720 – Hole ERS‑2025‑027: 11.0 g/t Au over 1.7 m (true width 1.0 m).

• Falcon 311 Zone

• Hole 857‑E‑108: 28.0 g/t Au over 10.0 m core length (true width 3.9 m, cut to 14.6 g/t).

• Dorset Zone

• Hole GS‑25‑219: 35.2 g/t Au over 1.0 m.

• Multiple lower‑grade intercepts ranging from 1.7–6.8 g/t Au across ~20 holes.

• Overall Drilling Activity (2025)

• ≈80,000 m drilled at Eagle River since Jan 2025.

• Nine‑month global model program underway with four rigs targeting an additional 40,000 m; results to feed a technical report update in mid‑2026.

• Future Plans

• Continue underground drilling through fall 2025 on all zones (6 Central, Falcon 311/720, Dorset, etc.).
• Incorporate high‑grade intercepts (e.g., hole 758‑E‑500) into the next resource update.
• Short‑term focus on ~40 surface targets (including Mishi‑Magnacon and Birch Vein).
• Medium‑term (~1–3 yr) drilling of ~30 priority targets; long‑term (~3+ yr) development of 106 identified targets across the 400 km² land package.

Notable Quotes

• Anthea Bath, President & CEO: “We’re highly encouraged by the latest underground exploration results… High‑grade intercepts over mineable widths are reminiscent of early drill results at similar depths… Work also remains on track across other underground targets.”
