Fredonia Mining Inc. Commences 10,000 Metre Drill Program At El Dorado–Monserrat Project Fredonia Mining Inc. announced the commencement of a 10,000-metre diamond drill program at its flagship El Dorado–Monserrat (“EDM”) gold project in the Deseado Massif, Santa Cruz Province, Argentina. The program marks an important step in advancing the Company’s systematic exploration strategy focused on expanding and upgrading the existing mineral resource at EDM. The program builds on the Company’s existing mineral resource estimate of approximately 2.25 million ounces of gold equivalent in the measured and indicated mineral resource categories. Gold equivalent grade (Au Eq) is derived using a gold price of USD 1,800/oz, and silver metal price USD 24/oz. Au Eq assumes Au and Ag recoveries of 90.0%. The limited metallurgical studies by Fredonia to date (selective Bottle rolls from Main Veins material) have indicated high (>90%) recovery of gold in oxide material. The Cerro Vanguardia mine to the east of EDM with similar mineralization reports recoveries higher than 90% for Au. Accordingly, the formula used for Au Eq is: Au Eq (g/t) = Au (g/t) + [Ag (g/t) x (24/1,800) x (0.9/0.9)]. The drilling campaign is designed to test high-priority targets across the broader EDM mineral system, with a focus on extending known zones of mineralization that remain open in multiple directions and increasing geological confidence within selected portions of the current resource through targeted infill drilling. The program will also evaluate newly identified exploration targets that demonstrate strong potential for additional gold-silver mineralization within the wider project area, with the objective of both expanding the overall resource base and enhancing its confidence ahead of ongoing development studies. The EDM project hosts a large-scale epithermal gold-silver system within the highly prospective Deseado Massif, a globally recognized metallogenic belt that contains multiple identified significant precious metals deposits. Fredonia believes the EDM system represents considerable potential for further resource growth, with mineralization remaining open along strike and at depth. The commencement of this drill program reflects Fredonia’s continued commitment to advancing EDM through disciplined, discovery-driven exploration aimed at unlocking the full-scale potential of the district. The Company is focused on systematically expanding the known mineral system and delivering new insights that support the long-term development of the project. Fredonia will provide updates as drilling progresses and as results become available.
