A former undergound Cu-Au-Ag-Fe mine. Located in the E½ sec. 2, T.8N., R.3W. (Morgan Butte 7.5 minute topo map), near the head of Amazon Wash, about 16 miles NE of Wickenburg, on the western flanks of the Bradshaw Mountains. Produced 1928-1958. Claims also extend into the NE¼NW¼ of sec. 2 and the W½NW¼ of sec. 12.
Mineralization is a vein deposit with a tabular ore body hosted in coarse, Precambrian granite complexly faulted & deeply oxidized. The principal mineralization is 2 nearly vertical veins, some 250 feet apart, that strike N.20ºW. & are traceable on surface for more than a mile.
The eastern vein (stronger mineralization) is generally 3 to 6 feet wide but pinches out in places. It is accompanied by an altered dike, apparently of intermediate composition, and has been cut by numerous transverse faults.
Ore control was faulting, shearing and igneous dikes. Ore concentration was oxidation at near surface. Alteration was minor to none.
Area structures include veins (and genetitically-related [?] dikes trend N10W to N40W and crosscut Precambrian fabric. The foliation in the Precambrian schist and gneiss trends N25E to N65E.
Workings include a 500 foot deep shaft.
