A Cu-Ag-Au occurrence located in sec. 28, T3S, R13E, SBM, 13.0 km (8.1 miles) W of Eagle Mountain (town), in the western Eagle Mountains, on National Park Service land (Joshua Tree National Park). MRDS database stated accuracy for this location is .
Mineralization is a vein deposit hosted in quartz monzonite. The ore body strikes N and dips 70W at a width of 1.22 meters. Quartz monzonite is cut by a series of parallel diorite dikes. The ore occurs along the contact between the diorite and quartz monzonite. Associated rocks include diorite dikes. Local rocks include Quaternary alluvium and marine deposits.
Workings include underground openings comprised of a 130 foot shaft with drifts N and S on the 100 foot level.
Analytical data results: 4 to 7% Cu, $8 (period values) Au/ton, 6 ounces Ag/ton.
