Shortwave infrared spectral analysis of hydrothermal alteration in the main and southwest Tintic mining district and exploration implications of the Silver City porphyry Cu-Mo-Au prospect, Tintic mining district, Utah, USA
The Main subdistrict of the Tintic Mining District located approximately 65 km south of Rio Tinto’s Bingham Mine, near Salt Lake City, Utah, has historically produced ~12.9 Mt of ore (Au, Ag, Cu, Pb and Zn) principally from Pb-Zn-Ag rich carbonate replacement deposits (CRD) and some Cu-Au rich fissure vein deposits. However, the causative intrusion, which may have formed a potential porphyry copper deposit, has never been identified. The Silver City Prospect area is situated on the southern edge of the Main subdistrict and the northern edge of the Southwest subdistrict and hosts multiple northeast ...
