PEA Supports Filo Mining’s Multimetal Filo del Sol Project
Preproduction capital is estimated at $792 million, including $71 million in capitalized pre-stripping. Mine production would be followed by heap leach processing to produce copper cathode and gold-silver doré.
The PEA estimates Filo del Sol’s lifeof- mine C1 cash costs on a co-product basis at $1.42/lb of copper equivalent. The C1 cash costs include at-mine cash operating costs, treatment and refining charges, royalties, selling costs, and transportation costs and are reported on a $/equivalent payable unit of the primary metal.
The Filo del Sol project is located 140 km southeast of Copiapó, Chile, and 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 project is based on a high-sulphidation epithermal copper- gold-silver deposit associated with a large porphyry copper-gold system.
The PEA contemplates mining the gold oxide, copper-gold oxide, and silver zones. Primary sulphide mineralization is not included in the PEA and remains a potentially significant upside opportunity for future development.
