Latitude & Longitude (WGS84): 35° 48' 12'' North , 115° 57' 35'' West
Latitude & Longitude (decimal): 35.80333,-115.95972


A former Zn-Au-Pb-Ag mine located in sec. 25, T20N, R9E, SBM, 0.9 km (0.6 mile) N of Crystal Spring (spring), on Bureau of Land Management land (located claim). Discovered and first operated in 1910. Owned & operated by John and Sylvia Prato (99% ?) (time frame uncertain). MRDS database stated accuracy for this location is 10 meters.

NOTE: There is another Crystal Spring Mine (primary name), located at Crystal Spring, listed as lying in San Bernardino County; however, it straddles the county line and part of it is apparently in Inyo County (as per adit symbols on the topo map).

The ore body strikes N70W and dips 60N at a thickness of 3 meters, a width of 75 meters and a length of 100 meters. The depth-to-top is 75 meters. The body is tabular in a fissure vein. The primary mode of origin was hydrothermal. Primary ore control was faulting and the secondary was lithology. The degree of wallrock alteration is unknown. Local rocks include Precambrian rocks, undivided, unit 1 (Death Valley).

Workings include underground openings.
