ESGold Corp. has commenced a second-phase Ambient Noise Tomography survey covering approximately 70 km² at its Montauban Gold-Silver Project in Québec. This program represents the largest geological investigation in the property's 110-year history and marks a seven-fold expansion of the company's initial 10 km² ANT survey completed in 2025. The expanded survey's importance lies in its potential to refine high-priority step-out drill targets and guide a focused spring 2026 drilling program. This drilling aims to evaluate the broader district-scale volcanogenic massive sulphide potential at Montauban, which could significantly impact resource estimation and project development timelines.
Results from the initial 2025 survey supported development of an integrated 3D geological model imaging mineralized architecture to approximately 900 metres in depth. That survey outlined at least two kilometres of strike length that remained open at the survey boundaries, suggesting substantial untapped potential that the current expanded investigation seeks to quantify. The scale of the current survey—covering 70 km²—represents a substantial commitment to understanding the property's full geological potential. By employing Ambient Noise Tomography technology across this expanded area, ESGold aims to create a comprehensive subsurface model that could reveal previously unidentified mineralized structures and guide efficient, targeted exploration efforts throughout the district.
This expanded geological work comes as ESGold advances toward anticipated production at Montauban in 2026. The timing of the survey results relative to the planned drilling program creates a critical path for resource definition and project advancement, making this geological investigation particularly significant for the company's operational timeline and strategic planning.
