Prismo Metals identifies copper porphyry target at Silver King

Prismo Metals has refined the geological profile of its Silver King project in Arizona, located approximately 3.4 kilometers from the major Resolution copper deposit operated by Rio Tinto and BHP. Following the completion of a surface program in the Pioneer Mining District, the company has identified a consistent system model suggesting a large-scale, deep-seated copper porphyry system rather than isolated silver veins.

The hydrothermal system now covers an area of 2.1 by 2.4 kilometers. A significant milestone includes the doubling of the mapped potassic alteration zone to approximately 650 by 300 meters. Geological findings, including rock samples from historical shafts, show enrichment in pyrite, magnetite, and secondary biotite. The company is currently preparing for deep drilling tests based on the observed Lowell-Guilbert zoning and hydrothermal signatures.
