[{"type":"text","content":" Vancouver, British Columbia--(Newsfile Corp. - March 6, 2025) - ESGold Corp. (CSE: ESAU) (OTCQB: SEKZF) (FSE: Z7D) (\"ESGold\" or the \"Company\") is pleased to report the results of metallurgical test work, conducted in collaboration with Dundee Sustainable Technologies (DST), under the Company's previously announced Gold-Silver Green Processing Initiative. The test work, part of ESGold's Clean Processing Initiative, assessed the applicability of DST's CLEVR Process™, a non-cyanide, environmentally friendly gold-recovery technology, on legacy tailings material from the Montauban Project. The tested sample[1] was collected from an on-site stockpile of tailings material grading 1.21g/t Au and 137g/t Ag (Duplessis et al., 2023*). The metallurgical results indicate high gold recovery potential using the CLEVR Process™, with gold recovery over 90.9%, following an oxidation pre-treatment process. The results provide preliminary insights into the applicability of this technology at the Montauban Project, though further studies are required to confirm economic feasibility. Key Findings: High Gold Recovery: CLEVR leaching achieved over 90.9% gold recovery, with final residue gold levels below the limits of detection, confirming near-total gold extraction. High-Grade Silver Values: The tested sample returned silver assay values of 760 g/t Ag, indicating strong silver recovery potential[2]. Increased Gold Grade After Oxidation: The initial assayed gold grade of the tested sample was 3.69 g/t Au and improved to 6.01 g/t Au post-oxidation. This significant increase in grade resulted from mass-loss associated with sulphide removal, which improved gold recovery (Gold and Silver Non-cyanide CLEVR process report). Successful Sulphide Removal: The oxidative thermal pre-treatment reduced sulphide content from 29.0% to 0.48%, significantly improving processing conditions. Fast Processing Time: Gold leaching was completed in one (1) hour, demonstrating the efficiency of the CLEVR Process™. Potential for Process Optimization: Future work will explore increasing solids concentration, reducing reaction time, and enhancing silver recovery to further enhance economic efficiencies. Note: Samples were processed at Dundee Sustainable Technologies' metallurgical facility in Canada. Standard QA/QC protocols, including the use of certified reference material...
