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 and Martiniere deposits together host 2.1 Moz indicated and 2.0 Moz inferred gold resources as of 2025.

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

• Strong shareholder base includes major industry figures and long-term supporters, with major shareholders such as Agnico Eagle (15%), Eric Sprott (9.9%), William Day Construction (5.4%), and management/insiders (0.7%).

• As of June 30, 2025, 1,099.8M shares outstanding (basic), 1,152.2M fully diluted, and ~$9.8M in cash.

Fenelon Project: PEA and Development Plan

• Positive PEA announced in March 2025, projecting a 16-year, mostly underground mine with after-tax NPV (5%) of $706 million at US$2,200/oz gold and 21% IRR.

• Average annual gold production estimated at 107,000 oz, with 127,000 oz/year in the first five years.

• Initial capex CAD 580 million, sustaining capex CAD 450 million; annual after-tax free cash flow projected at CAD 120 million.

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

• 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.

• Capital allocation covers mill, paste plant, tailings, water treatment, and infrastructure, with detailed breakdowns provided.

• Total cash costs estimated at US$851/oz and all-in sustaining costs at US$1,046/oz over the life of mine.

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