Gem Mine , San Benito County, California

A former gemstone and specimen occurrence/mine located in the SW¼NE¼ sec. 25, T18S, R12E, MDM, 1.2 km (0.8 miles; ca. 3,937 feet) SSW of Santa Rita Peak (coordinates of record) at the headwaters of the San Benito River, on formerly private (patented) land, now turned over to the state of California. The MRDS database stated the accuracy for this location is 100 metres.

Mineralisation is a gemstone deposit. The deposit consists of natrolite veins cutting a glaucophane schist inclusion in a serpentinite body. Local rocks include ultramafic rocks, chiefly Mesozoic, unit 3 (Coast Ranges and Western Klamath Mountains).

Note: The majority of specimens from this locality have been prepared by dissolving away the enclosing natrolite with hydrochloric acid.

Workings include unspecified underground openings (the topo map reflects a large shaded area of mining activity with one adit symbol labelled "gem mine" at this point).
