Cerro de Pasco conducted over 110 metallurgical tests, achieving approximately 94% silver recovery and over 92.5% total sulphide capture in mini-pilot plant results. The project, located in Cerro de Pasco, targets tailings from historical mining (1921-1992) and plans to utilize a two-concentrate flowsheet, producing high-grade pyrite and base metal concentrates.
Mineralogical analyses indicate significant pyrite content, suggesting applications in fertilizer and chemical industries. Further evaluations for gallium and indium are ongoing. The company anticipates additional metallurgical updates in the second half of 2026 as it prepares for its first mineral resource estimate, with market cap reported at CA$411.79 million.
