ESGold Launches 70 km2 District-Scale ANT Survey at Montauban Following 3D Model Identifying Deep, Expanding 2 km Mineralized Corridor

Executive Summary

• ESGold Corp. launched a second‑phase Ambient Noise Tomography (ANT) survey covering ~70 km² at the Montauban Gold‑Silver Project, a seven‑fold increase over the 2025 pilot survey.
• The expanded program aims to confirm continuation of a mineralized corridor that extends to ~900 m depth and >2 km strike, and to identify additional high‑grade lenses for step‑out drilling planned for spring 2026.
• Results will be integrated into an updated 3D geological model to refine drill targets and support the company’s dual‑track strategy of near‑term production (expected 2026) and district‑scale discovery.

Key Details

• Survey Scope: 70 km² (≈7× the original 10 km² area), covering the most prospective zones of the consolidated Montauban land package.
• Depth Penetration: Imaging from 50 m to at least 900 m, with potential for deeper extension beyond current limits.
• Geophysical Technology: Utilizes Caur Technologies’ ultra‑sensitive “Geodes” (10× more effective than traditional geophones) combined with AI‑driven modeling and satellite‑assisted geophysics.
• Initial Findings (2025 Survey):
• Mineralized architecture extending to ~900 m depth, significantly deeper than historic drilling (max ≈250 m).
• ≥2 km of strike length identified within the original 10 km² footprint.
• Corridor widens at depth and remains open where the survey ended.
• Program Objectives:
• Determine if the interpreted corridor continues along strike beyond the initial boundaries.
• Assess potential for additional mineralized lenses across the broader district‑scale framework.
• Generate high‑resolution, three‑dimensional subsurface images to guide step‑out drill target selection.
• Impact on Exploration Plan: Data will feed into an updated predictive 3D model and define high‑priority drill targets slated for execution in 2026.
• Production Context: ESGold’s processing facility is fully permitted, construction‑ready, with component procurement underway; the survey proceeds alongside near‑term production ramp‑up.
• Qualified Person Review: André Gauthier, P.Geo., Director and QP, has reviewed and approved the technical content under NI 43‑101 standards.
