A former underground Ag-Au-Cu-Ni-Co-As mine located in the W½ sec. 4, T8N, R3W (Morgan Butte 7.5 minute topo map), near Wickenburg. Claims also extend into the NE¼NW¼SW¼ of sec. 4.
Mineralization is ore in bands and lenses. Ore control was faulting, shearing and igneous activity - dikes. Ore concentration was oxidation at near surface. Alteration was minor to none.
Area structures include veins (and genetically related [?] dikes) that trend N10W to N40W and crosscut Precambrian fabric. Foliation in Precambrian schist and gneiss trends N25E to N65E.
