A former underground Au-Ag-Cu mine located 4½ miles North of Wickenburg. Started in the 1870's. Discovered by [?] and owned by G.B. Upton (1900- ); Oro Grande Consolidated Mines (1929-1934). Produced 1904-1932.
Mineralization is a tabular ore body hosted in an altered diorite with lenses of basic schist and irregular dikes of aplite and pegmatite. At the mine a fractured to brecciated zone, in places more than 100 feet wide, forms the SE wall of a nearly vertical fault that strikes N.37ºE. Portions of this zone are cut transversely by narrow, irregular veins and stringers of white quartz in the walls of which are developed pseudomorphs of limonite after pyrite. The principal orebody occurs near the SW exposure of the brecciated zone. This body was irregular in shape and several 10's of feet in maximum width. Ore consists of brecciated country rock cemented with brown to black limonite, calcite & coarsely-crystalline, glassy quartz. Ore concnetration was oxidation at near-surface (less than 300 feet of depth).
Area structures include veins and genetically-related [?] dikes that trend N-S or subparallel (N30E) to schist. Foliation in the Precambrian schist trends N35E.
Workings include a 340 foot deep shaft (1900-1903) and a few thousand feet of development work.
