Esgold talks ANT 3-D geological model for Montauban

Executive Summary

• Esgold Corp. has completed an integrated 3-D geological model using Ambient Noise Tomography (ANT) for its Montauban project in Quebec, revealing a deep, expanding mineralized corridor with significant district-scale exploration potential.
• The model identifies mineralization extending to depths of approximately 900 meters and along a strike length of at least two kilometers, with trends remaining open beyond the current survey area, suggesting substantial upside beyond historically mined zones.
• The company plans to expand ANT coverage, integrate additional geophysical data, and initiate a stepout diamond drilling program in early spring 2026 to validate these targets, while simultaneously advancing toward near-term production in 2026.

Key Details

• Model Depth and Scale: The ANT-based 3-D model illustrates mineralized architecture extending to depths of approximately 900 meters, significantly deeper than historical exploration which was mostly confined to shallow depths (~50 meters) with the deepest holes reaching only ~250 meters.
• Strike Length: The model outlines approximately two kilometers of strike length within the current survey area, with mineralization appearing to widen at depth.
• Open Trends: Mineralized trends remain open and are bounded by the limits of the existing ANT coverage, indicating potential continuation beyond the current study area in multiple orientations.
• Geological Controls: The model identifies coherent lithological and structural corridors comparable to historical Montauban mineralization. Dominant north-northwest- and northeast-trending structures are interpreted as first-order controls on hydrothermal fluid flow, consistent with large polymetallic volcanogenic massive sulphide (VMS) systems.
• Exploration Plan: Next steps include expanding ANT coverage to evaluate the district-scale corridor, integrating additional geophysical datasets, and developing a stepout diamond drilling program to test high-priority targets.
• Drilling Timeline: The company anticipates commencement of drilling in early spring 2026, subject to permitting, access, and logistics.
• Production Context: Exploration activities are advancing in parallel with the company's tailings project, with Montauban moving toward production in 2026. Any additional mineralization delineated has the potential to be integrated into future mine plans.
• Technical Methodology: The model was prepared by Geomatic World Inc. using seismic velocity data acquired by CAUR Technologies. ANT is a passive seismic method leveraging ambient vibrations to image subsurface density contrasts.
• Qualified Person: The technical information was reviewed and approved by Andre Gauthier, PGeo, a director of Esgold and a qualified person under National Instrument 43-101. The interpretations are conceptual and do not constitute a mineral resource or reserve.

Notable Quotes

• Gordon Robb, CEO: "This is the most important technical milestone in Esgold's history. The integrated 3-D model has fundamentally changed how we understand Montauban... The scale indicated by this work is beyond what we had originally envisioned, and it reinforces our conviction that Montauban has the potential to evolve into a much larger mineral system."
• Andre Gauthier, Director/Senior Consulting Geologist: "The identification of deep-seated structural corridors, lithological continuity and coincident geochemical anomalies in areas that have never been drilled is highly encouraging... This level of structural continuity at depth is particularly notable given the complexity of Grenville-age terranes and helps explain why this system was not previously recognized."
