Interview with Mark Petersen, Senior Geological Consultant of Wallbridge Mining Our previous interview: https://www.cruxinvestor.com/posts/wallbridge-mining-wm-updated-resource-will-delight-market-2169 Recording date: 27th November 2025 Wallbridge Mining is pursuing a calculated two-pronged approach across its Quebec gold assets, balancing near-term development at Fenelon with aggressive exploration at the Martiniere system. Mark Peterson, Senior Geological Consultant with over 40 years of experience, leads the geological strategy following his tenure at New Gold. At Fenelon, the company has fundamentally restructured its resource model, simplifying mineralized domains from over 100 discrete zones to 16 user-friendly envelopes. This redesign better aligns with the project's 40-meter drill spacing and creates practical targets for underground mining operations. The deposit features coarse visible gold throughout all rock types, supporting bench-scale metallurgical test results showing 30% initial gravity recovery and 96% total recovery—characteristics that could enable simpler processing and lower operating costs. The company's preliminary economic assessment incorporates existing underground infrastructure from a flooded historic pit, providing capital-efficient portal access. Despite higher upfront costs, Wallbridge selected dry-stack tailings to address both industry trends and site-specific challenges posed by Quebec's saturated glacial overburden terrain. Approximately one million ounces of resource remain excluded from the current mine plan, offering future expansion potential. At Martiniere, Peterson has pivoted to testing fundamental system scale rather than incremental resource growth. The exploration team employs aggressive 150-meter drill spacing across a two-kilometer strike length, rapidly covering prospective ground while accepting that subsequent infill will be required. First-principles structural remodeling identified 14 distinct fault structures along the Bug Lake deformation corridor, with recent drilling encountering mineralization including three meters at approximately seven grams per tonne half a kilometer from the Horsefly area. The critical next phase involves a 50,000-75,000 meter infill drilling program at Fenelon to convert inferred resources to indicated category, while a mineral inventory assessment at Martiniere will determine whether data supports the target of a two-million-ounce-plus system before committing to closer-spaced delineation drilling.
