Filo Mining Corp. announced the results of a positive pre-feasibility study (PFS) at its 100% owned Filo del Sol project located on the border of Region III, Chile and San Juan Province, Argentina. Filo del Sol hosts a high-sulphidation epithermal copper-gold-silver deposit associated with a large porphyry copper-gold system. The project is located in the Andes Mountains on the border of Chile and Argentina, approximately 140 km southeast of the city of Copiapó. The project is covered under the Mining Integration and Complementation Treaty between Chile and Argentina, which provides the framework for the development of cross-border mining projects. The PFS contemplates that Filo del Sol would be mined using conventional open pit methods. From the open pit, ore would be trucked to a conventional two-stage crusher, designed to process 60,000 tonnes per day of ore. Crushed ore would be treated by sequential heap leaching, to extract copper and subsequently gold and silver from the ore followed by hydrometallurgical processing to produce copper cathodes and gold-silver doré. Groundwater for the process plant would be supplied from nearby aquifers to the plant site, and power would be supplied via 127 km of power line construction to connect to the Chilean national grid. Copper cathode and gold-silver doré would be transported by truck to Puerto Caldera which is located approximately 245 km by road from the plant site. Approximately 60 km of the existing road between site and port would require upgrade to accommodate the truck traffic; the remaining distance comprises public highway.
