ESGold Confirms Final Processing Methodology at Montauban as Construction Nears Completion

Metallurgical work validates processing approach for railway tailings; construction progressing ahead of schedule and exploration planning accelerating

VANCOUVER, BRITISH COLUMBIA / ACCESS Newswire / October 28, 2025 / ESGold Corp. ("ESGold" or the "Company") (CSE:ESAU)(OTCQB:ESAUF)(FSE:Z7D) is pleased to report that recent metallurgical work conducted at its fully permitted Montauban Gold-Silver Project in Quebec has validated the Company's processing strategy for the railway tailings and other feedstock at the site.

Gravity separation tests confirmed that concentrate grades from the railbed material were not sufficient to allow for direct gold and silver pouring. The results confirmed that while gravity separation did not produce a concentrate sufficient for direct gold or silver pouring, all Montauban feedstock, including the railway tailings, will be processed directly through the Merrill Crowe closed circuit as part of the final phase of mill construction. This outcome provides valuable validation of the process and confirms the Company's path forward before finalizing equipment procurement.

All metallurgical work was supervised by Edmond St-Jean, P.Eng., with testing completed at the Montauban facility and laboratory analyses performed by ALS Global in Val-d'Or, Quebec.

Key Highlights

• Processing Strategy Confirmed: Metallurgical results validated the Merrill Crowe closed circuit as the optimal processing path for all Montauban feedstock, ensuring operational efficiency across tailings and railbed material.

• De-Risked Equipment Procurement: The results provide critical technical confirmation ahead of finalizing purchase and installation of processing components.

• Construction Advancing Ahead of Schedule: The main mill building is nearing completion, with concrete curing and interior finishing underway.

• Infrastructure Expansion: The gold room and on-site laboratory are being constructed to support production assays and future exploration analysis.

• Exploration Momentum: Advanced 3D geological modeling is in its final stages and will guide an expanded exploration program designed to test deeper and newly defined mineralized structures.

Gordon Robb, CEO of ESGold, commented:

"This work gave us exactly what we needed - confirmation of the correct processing path before finalizing our equipment procurement. The metallurgical data supports our plan to process all Montauban feedstock through the Merrill Crowe circuit to be built during the final phase of construction, giving us the confidence to move ahead decisively. The site looks excellent, and construction is progressing faster than anticipated. Our gold and lab rooms are coming together beautifully, and we're preparing to transition into the installation phase. I want to thank our team for their dedication and precision in getting us to this point. With construction nearing completion and exploration planning accelerating, ESGold is entering a very exciting phase as we move closer to first production."
