About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Mine Description
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."

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Workings): 36 MATCHES DESCRIPTIONS BY BOTH HILL (1915, P 193,) AND BONHAM (1969, P 78)
Comment (Workings): ALTERED ZONE CRUDELY CIRCULAR, APPROX 1 MILE IN DIA, CENTERED OVER A GRANODIORITE PORPHYRY OF TERTIARY AGE. THE GD PORPHYRY INTRUDES MESOZOIC GRANODIORITE, MESOZOIC METAVOLCANIC ROCKS, AND ANDESITE OF THE TERTIARY ALTA FORMATION. ALL OF THESE ROCKS HAVE BEEN HYDROTDERMALLY ALTERED, (PYRITIZED) BLEACHED. THE ALTERED ROCK FROM BENEATH THE ZONE OF WEATHERING CONSISTS ESSENTIALLY OF PYRITE, QUARTZ, SERICITE. PYRITE OCCURS IN VEINLETS AND DISSEMINATED THROUGHOUT THE ROCK.

Nevada Gold
Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
