Location: Camp Six was an exploration camp with two trailers and several smaller buildings that El Paso Natural Gas Company used in the 1970's. Still and others (2002) retained that name for the prospect. It is about 0.4 mile southwest of Peak 4362 at the head of Groundhog Basin. The prospect is about 0.6 mile southeast of the center of section 7, T. 62 S., R. 86 E. The location is accurate.
Geology: The rocks in the prospect area are part of a belt of Mesozoic or Paleozoic sedimentary and volcanic rocks that have been metamorphosed to Tertiary or Cretaceous schist and gneiss. The belt is about 1 1/2 mile wide and strikes northwest (Brew, 1997; George and Wyckoff, 1973). The metamorphic rocks are bounded on the east by a thick, regionally extensive, 60 to 70 Ma tonalite sill and on the west by a 90 Ma granodiorite pluton (Brew, 1997 Still and others, 2002). On the north side of Groundhog Basin, about a mile to the northwest, the metamorphic rocks are intruded by a 16.3 Ma biotite 'tin' granite pluton about 1,000 by 2,0000 feet in size. The granite is probably the source of the numerous rhyolite dikes and sills that extend from it and the mineralization in the area (Newberry and Brew, 1989). Camp Six was an exploration camp with two trailers and several smaller buildings that El Paso Natural Gas Company used in the 1970's for their work in the area. Still and others (2002) retained that name for the prospect here where El Paso did some surface geology and sampling. As Still and others did later, El Paso identified the mineralization as narrow silicified, sheared zones along the margins of rhyolite sills and in gneiss. The zones contained pyrrhotite, chalcopyrite, galena, and sphalerite. Samples collected by Still and others contained up to 58 parts per million (ppm) silver, 1,976 ppm copper, 1,324 ppm lead, and 9.5 percent zinc. The mineralization is almost certainly of the same origin and age as the nearby Groundhog Basin prospect (PE040).
Workings: Camp Six was an exploration camp with two trailers and several smaller buildings that El Paso Natural Gas Company used in the 1970's. Still and others (2002) retained that name for the prospect here. El Paso did some surface geology and sampling, as did Still and others later.
Age: Probably 16.3 Ma based on a genetic tie to a nearby, zinnwaldite 'tin' granite (Newberry and Brew, 1989).
