The program was\ncompleted by independent metallurgical consultants, SGS Canada Inc.,\nat its testing facilities in Lakefield, Ontario.\n \n \n \n \n The metallurgical testing was conducted as part of the\nongoing Pre-Feasibility Study (\"PFS\") for Diablillos, and\nfurther complements the positive metallurgical results achieved for\nthe JAC and Fantasma deposits, which were announced on\n \n \n June 1, 2023\n \n \n .\n \n \n \n \n Key takeaways from the PFS-level metallurgical test\nwork include:\n \n \n \n \n \n \n Recovery rates at the Oculto deposit are expected to\nrange between\n \n \n 82% - 86% for\nsilver\n \n \n and\n \n \n 84% - 89% for gold.\n \n \n These\nresults represent a significant increase\n \n \n over\nthe average recovery rates of 73.5% for silver and 86% for gold used\nin the 2022 Preliminary Economic Assessment (“PEA”).\n \n \n \n \n \n \n A substantial percentage of the silver and gold at\nOculto can be recovered by gravity separation\n \n \n which results in\n \n \n higher recovery rates and lower processing costs\n \n \n .\n \n \n \n \n \n \n Importantly,\n \n \n fine grinding is not necessary\n \n \n with the most\nefficient recoveries achieved at a grind size of 150 microns for both\ngravity and cyanidation and an optimal retention time of 36 hours.\n \n \n \n \n \n \n John Miniotis, President and CEO, commented, “These\nmetallurgical results are extremely positive, and further raise the\npotential for a significant improvement in the project economics at\nour world-class Diablillos project.  The ability to recover a\nsubstantial amount of gold and silver through the use...
