East Park City Mining District
The Elkhorn (East Park City) mining district is in the Wasatch Range about 6 mi east-southeast of Park City in northernmost Wasatch County. The district was organized in 1975 and is an insignificant Pb-Ag producer. The Park Konold is the only mine in the district with recorded production.
The Elkhorn district is situated on the Bingham-Park City mineral belt in the Middle Rocky Mountain province. The district is largely underlain by the five phases of the Park Premier stock intruding partly coeval volcanic rocks. The area was explored by the Anaconda Company from the 1950s to 1980s for porphyry Cu and related skarn mineralization. The geology of the area is well described by John (1989). The Park Premier stock exhibits multiple granodiorite porphyry phases, stockwork veining, and large areas of pervasive porphyry-style alteration: hydrothermal biotite ±actinolite, quartz-sericite-pyrite, propylitic, and advanced argillic. Biotite alteration has been dated at about 33.5 Ma (John and others, 1997). Indicated grades of the porphyry mineralization are less than 0.2% Cu, 0.01% Mo, and 617 ppb Au (USGS Model 17). The porphyry mineralization is overprinted by younger high-sulfidation epithermal veins (USGS Model 25e) (John, 1989).
The western part of the Elkhorn district and much of the known porphyry system is now covered by the Jordanelle Reservoir.
