The Nevada Central mine is located in sec. 36, T. 20 N., R. 18 E. approximately 4.5 miles west of Reno and 2 miles south of Peavine Peak. There is no recorded production from the mine.
The workings at the Nevada Central property include several open cuts, pits, and trenches, several short adits and one ad it, now caved, which was 600 feet long, and a shaft. These workings explore a mass of pyritized, hydrothermally altered rock which has undergone intense, near-surface bleaching. The bleached rock occurs in the zone of weathering and consequent oxidation of pyrite. The resultant rock is a mixture of quartz, iron oxides, sericite, clay minerals and minor gypsum and calcite.
The altered zone is a crudely circular area, approximately 1 mile in diameter, centered over a granodiorite porphyry intrusive of Tertiary age. The granodiorite porphyry intrudes Mesozoic granodiorite, Mesozoic metavolcanic rocks, and andesite of the Alta Formation. All of these rocks have been hydrothermally altered, pyritized, and bleached, and it is very difficult to discriminate between the various rock types within the altered area.
The altered rock from beneath the zone of weathering consists essentially of pyrite, quartz, and sericite. The pyrite occurs in veinlets and also disseminated throughout the rock. Much of the altered rock is brecciated and is cut by small veinlets of pyrite-bearing quartz. Hill (1915, p. 195) reported that minor amounts of chalcopyrite occurred in the "ore body."
