ESGold Corp. (CSE: ESAU) (OTCQB: ESAUF) (FSE: Z7D) is pleased to provide an update on its 2026 diamond drilling program at the Montauban Project, located approximately 80 kilometres west of Québec City, Québec.

As of September 15, 2026, ESGold had advanced 19 drill holes for a cumulative total of approximately 2,030 metres, marking an important milestone in the Company’s 2026 exploration program.

Importantly, drilling continues to intersect alteration, quartz-carbonate veining and locally sulphide-bearing intervals within the geological environment associated with the historic Montauban mineralized system.

Observed sulphides to date include pyrite, pyrrhotite and galena, locally occurring within or adjacent to quartz-carbonate veins, altered gneissic units and structurally affected intervals.

Approximately 400 core samples have now been submitted to SGS Laboratories in Val-d’Or for analysis, with assay results pending.

“Passing 2,000 metres is an important milestone in our 5,000-metre program, but what is particularly encouraging for us is what we continue to see in the core,” said Gordon Robb, CEO and Director of ESGold. “We are repeatedly encountering alteration, quartz-carbonate veining and sulphide-bearing intervals within the geological environment associated with the historic Montauban mineralized system.

“With approximately 400 samples now at SGS Laboratories in Val-d’Or, the next step is determining the significance of what we are seeing. At the same time, drilling continues as we test how this system may extend beyond the historic workings and at depth. Every hole is giving us more information to integrate with the historic mine data, ANT geophysics and our 3D geological model.”

Highlights

• ESGold has completed approximately 2,030 metres across 19 drill holes as part of its planned 5,000-metre 2026 diamond drilling program.
• Drilling has repeatedly encountered alteration, quartz-carbonate veining and locally sulphide-bearing intervals within the geological environment surrounding the historic Montauban mineralized system.
• Observed sulphides include pyrite, pyrrhotite and galena, locally associated with quartz-carbonate veining, alteration and structurally affected intervals.
• Approximately 400 core samples have been submitted to SGS Laboratories in Val-d’Or for assay.
• Nine drill holes have intersected historic underground workings or voids, providing valuable geological control for reconciling modern drilling with the geometry of the former mine.
• Drilling remains ongoing as ESGold evaluates the potential continuation of the Montauban system outside and below the historic mine workings.

Sulphide-Bearing Intervals Observed in Drill Core

Core logging completed to date has identified repeated sequences of amphibolite and quartz-feldspar, biotite- and muscovite-bearing gneisses together with zones of silicification, chlorite-sericite alteration, deformation and quartz-carbonate veining.

Sulphides have been observed within or adjacent to quartz-carbonate veins, altered gneissic units and structurally affected intervals in holes including MM-26-03, MM-26-04 and MM-26-11.

These observations are significant from a geological targeting perspective because they provide direct information on the alteration, structural features and lithological contacts associated with the historic Montauban mineralized environment.

Visual observations are not necessarily indicative of economic mineralization and laboratory assays are required to determine metal grades.

Testing Beyond the Historic Mine

The 2026 drill program is designed first to confirm the presence and continuity of mineralization along the main mineralized structure, and then to extend beyond the historical underground workings to test additional targets and potential extensions of the system. The drilling program is testing the geological interpretation developed from historical mine information, ESGold’s drillhole compilation, ANT surveys by CAUR Technologies, and 3D geological modelling by Geomatic World.

Each new drill hole provides direct geological information that can be incorporated into the evolving 3D model and compared with features interpreted through the ANT surveys.

Assays and Next Steps

Core logging, cutting and sampling are continuing as drilling advances toward the planned 5,000 metres.

Approximately 400 samples have been submitted to SGS Laboratories in Val-d’Or for analysis. Assay results will be reported as they are received, reviewed and validated under the Company’s QA/QC procedures.

The Company will use the combined geological, structural and assay information to refine the integrated 3D geological model, correlate new drilling with historical mineralized zones and underground workings, and prioritize additional shallow and deeper targets designed to test potential extensions of the Montauban system.

Next Steps

Core logging and sampling are continuing as the drilling program advances.

As part of this first exploration phase, the entire drill core is being sampled and analyzed to ensure that the maximum amount of geological and geochemical information is collected.

The Company intends to use the combined geological, structural and assay information to:

• refine the integrated 3D geological model;
• evaluate the relationship between mineralization, lithological contacts, alteration and structural features;
• prioritize additional shallow and deeper drill targets designed to test potential extensions of the Montauban system.

Laboratory assay results will be reported once received, reviewed and validated in accordance with the Qualified Person’s QA/QC procedures.
