Next Steps Toward Production

ESGold has initiated procurement of the processing equipment required to complete the Merrill Crowe circuit, including clarifying tanks, filtration units, and vacuum systems. Once all components are received, the team will move into system integration and commissioning, ensuring seamless alignment with the plant’s clean, closed-circuit design.

The Company anticipates commissioning activities to follow shortly after installation, leading to the first gold and silver production from Montauban in 2026.

Quote from Gordon Robb, CEO

“Completing the mill building is a defining achievement for ESGold. This milestone transitions us from construction to commissioning and represents tangible progress toward near-term production,” said Gordon Robb, CEO of ESGold Corp. “Our team has done an incredible job keeping the project on schedule. We are now focused on ordering, installing, and integrating equipment to bring Montauban online.

Exploration Planning and 3D Model Progress

As construction advances, ESGold’s geological and technical teams are completing the final stages of the comprehensive 3D geological model for the Montauban district. This model integrates geophysical, historical, and ANT survey data to refine drill targets and identify deeper mineralized structures. The results will form the foundation for an expanded exploration strategy designed to unlock Montauban’s broader discovery potential.

Upcoming Milestones

Completion and public release of the Montauban 3D geological model to guide exploration and resource expansion.
Initiation of a targeted exploration and drill program based on newly interpreted structural data.
Sourcing and procurement of key processing equipment to advance construction and readiness for commissioning.
Delivery and installation of Merrill-Crowe circuit components to enable on-site gold and silver recovery.
Progress toward first gold and silver production in 2026, marking the transition from construction to operations.

Why This Matters to Investors

Completion of the Montauban mill building de-risks ESGold’s transition to production and demonstrates the Company’s ability to execute efficiently. With funding secured, construction complete, and procurement underway, ESGold is well positioned to move from build to commissioning. The combination of near-term cash flow potential and large-scale exploration upside continues to define ESGold as one of Canada’s most advanced, scalable clean-mining developers.

Qualified Person

The technical content of this news release has been reviewed and approved by John Langton (P.Geo.), a Qualified Person under National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The bench testing summarized in this press release was supervised by Edmond St-Jean, Ing., whose underlying report notes that samples were collected from the Montauban site and used as received for metallurgical analysis. Data and results are preliminary but considered reliable for disclosure purposes.

Reliance on Updated Preliminary Economic Assessment (PEA)

ESGold’s advancement of the Montauban Project is supported by the results of its Updated Preliminary Economic Assessment (PEA), which remains the current technical study for the property. The PEA outlined an after-tax NPV (5%) of C$24.27 million and an after-tax IRR of 60.3 percent, along with a pre-tax NPV (5%) of C$44.53 million and a pre-tax IRR of 105.1 percent, underscoring robust economics with a payback period of less than two years from production start. The study demonstrated strong project economics with low capital intensity and high operating margins, highlighting the potential for early cash flow from reprocessing of historical tailings and production of gold and silver dore

Cautionary Note on Production Decision

The Company cautions that its decision to proceed with site construction and procurement of processing equipment at the Montauban Project is not based on a feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly, there is increased uncertainty and a higher risk of economic or technical failure associated with the Project’s development compared with projects supported by a full feasibility study and defined mineral reserves. The Company’s production decision has been made using information contained in its updated PEA, historical operating data, metallurgical testing, and management’s assessment of the Project’s potential for sustainable operations.
