ESGold Corp. (CSE: ESAU | OTCQB: ESAUF | FSE: Z7D) has announced a significant milestone in its 2026 exploration campaign at the Montauban Project in Québec, completing approximately 2,030 metres across 19 drill holes as part of a planned 5,000-metre diamond drilling program. The company reports repeated intersections of alteration, quartz-carbonate veining, and sulphide-bearing intervals within the geological environment of the historic Montauban mineralized system. Approximately 400 core samples have been submitted to SGS Laboratories in Val-d'Or for assay, with results pending. Investors may be watching closely as laboratory results will be key to evaluating the geological significance of what has been observed in the drill core.

Key Points

  • ESGold Corp. (CSE: ESAU | OTCQB: ESAUF | FSE: Z7D) is a pre-production mining company advancing the Montauban Gold-Silver Project in Québec
  • Drilling has surpassed 2,030 metres across 19 holes, marking the halfway point of a 5,000-metre program
  • Sulphides observed include pyrite, pyrrhotite, and galena; approximately 400 samples are at SGS Laboratories in Val-d'Or awaiting assay
  • Investors should watch for assay results, which will be released once received, reviewed, and validated under the company's QA/QC procedures

Sulphide Observations and Core Geology at Montauban

Core logging at the Montauban Project has identified repeated sequences of amphibolite and quartz-feldspar gneisses alongside zones of silicification, chlorite-sericite alteration, deformation, and quartz-carbonate veining. Sulphides — including pyrite, pyrrhotite, and galena — have been observed within or adjacent to quartz-carbonate veins, altered gneissic units, and structurally affected intervals in holes MM-26-03, MM-26-04, and MM-26-11. The company emphasises that visual observations are not necessarily indicative of economic mineralisation, and laboratory assays are required to determine metal grades.

Historic Workings Provide Geological Control for 3D Modelling

Nine drill holes have intersected historic underground workings or voids at the Montauban site, which the company states provides valuable geological control for reconciling modern drilling with the geometry of the former mine. ESGold is integrating new drill data with ANT geophysical surveys conducted by CAUR Technologies and 3D geological modelling by Geomatic World. The release states each new hole is contributing direct geological information that refines the evolving 3D model and supports prioritisation of additional shallow and deeper targets.

Program Design Targets Extensions Beyond Historic Mine Boundaries

The 2026 drill program is structured to first confirm mineralisation continuity along the main mineralised structure, then test potential extensions of the system beyond the historic underground workings and at depth. The company states the entire drill core is being sampled and analysed to maximise geological and geochemical information collected. Assay results will be reported as they are received, reviewed, and validated in accordance with the Qualified Person's QA/QC procedures. The scientific and technical content has been approved by Merouane Rachidi, Ph.D., P.Geo., an independent Qualified Person under National Instrument 43-101.
