ESGold Confirms Merrill Crowe System as Optimal Processing Method for Montauban Gold-Silver Project

ESGold Corp. (CSE: ESAU) (OTCQB: ESAUF) has confirmed that metallurgical work at its fully permitted Montauban Gold-Silver Project in Quebec validates the company's processing strategy, identifying the Merrill Crowe closed circuit as the optimal processing path for all site feedstock, including railway tailings. The findings represent a significant milestone in de-risking the project's development timeline and equipment procurement strategy.

Gravity separation tests conducted during the metallurgical analysis revealed that concentrate grades were insufficient for direct gold and silver pouring, leading to the definitive conclusion that all material will be processed through the Merrill Crowe system during the final construction phase. This technical validation provides crucial certainty for the project's operational planning and capital allocation decisions. The results, supervised by Edmond St-Jean, P.Eng., and analyzed by ALS Global in Val-d'Or, support ongoing mill construction activities that are reportedly ahead of schedule.

The confirmation of the Merrill Crowe processing method carries substantial implications for the project's economic viability and development timeline. By establishing a clear processing pathway, ESGold can proceed with more confident equipment procurement and operational planning, potentially accelerating the timeline to production. The company noted continued infrastructure expansion at the site, including progress on the gold room and laboratory facilities, further indicating momentum toward operational readiness.

ESGold also reported completion of advanced 3D geological modeling that will guide an expanded exploration program at the Montauban property. This comprehensive modeling approach enhances the company's understanding of the mineral resource and supports targeted exploration efforts. The full details of the metallurgical findings and project updates are available in the company's official release at https://ibn.fm/bHKim.

The validation of the processing strategy comes at a critical juncture for ESGold as the company advances its flagship Montauban property toward production. Located 80 kilometers west of Quebec City, the project represents a significant opportunity in the Quebec mining landscape. The technical confirmation provides investors and stakeholders with increased confidence in the project's operational framework and development pathway, potentially influencing future financing decisions and partnership opportunities in the competitive mining sector.
