A former small underground W-Au-Ag-Pb-Zn-Cu group of 3 unpatented claims located in the NW ΒΌ sec. 13, T.20S., R.9E., about 2 miles North of Las Guijas. Discovered 1936. Produced 1936-1940. Owned and operated by E. & L.G. Fernstrom (1940).
Mineralization is small, spotty, irregular oreshoots containing wolframite and minor scheelite, and sulfides in a lensing and branching quartz-fissure vein cutting Cretaceous andesite. Ore control was the narrow quartz vein.
Workings include a shallow, 40 foot deep, shaft and a 70 foot adit. Produced some 10,000 pounds of picked tungsten concentrates in the late 1930's. The mine was closed in 1940 when the vein became too narrow to work.
