Wallbridge Mining Company (WM) 2025 Precious Metals Summit Beaver Creek Conference summary

Project overview and resource updates

• Controls 830 sq km of prospective ground along the Sunday Lake Break, adjacent to a major producing gold mine.

• Fenelon project has 3.4 million ounces in combined indicated and inferred resources at ~3.5 g/t; Martinière has 730,000 ounces.

• Company transitioned from nickel to gold focus, divesting all nickel assets.

• Strong shareholder base includes major industry figures and long-term supporters.

Fenelon project: new PEA and development plan

• New PEA envisions a 16-year, mostly underground mine with 107,000 oz/year average production.

• Average annual free cash flow projected at CAD 120 million; initial capex CAD 580 million, sustaining capex CAD 450 million.

• Phased approach: 2 years pre-production, 15 years underground mining at 3,000 tpd, final 2 years with a small open pit.

• Shifted from previous 7,000 tpd open pit/underground concept to a 3,000 tpd underground-only plan for manageability and permitting advantages.

• Only 50% of current resource included in mine plan, leaving significant future upside.

Engineering, environmental, and operational highlights

• Dry stack tailings and underground waste rock backfill minimize surface footprint and water management needs.

• Camp-based operation with good road access and proximity to power grid; potential for further cost reductions.

• Pre-feasibility study roadmap in development, with more clarity expected by early next year.

• Base case NPV of $706 million, 21% IRR, 4-year payback at $2,200 gold; at $3,000 gold, IRR exceeds 30% and payback drops to 2.5 years.
