A former underground Au-Ag-Mo-Mn-Cu mine located on 88 claims (1920) in sec. 1, T1N, R8E, about ¾ mile SE of Goldfield, 2 miles ESE of Saddle Rock, between the Superstition and Goldfield Mountains, 36 miles East of Phoenix, on private land. Started in the early 1890's and originally owned by C. Hall & D. Sullivan. Open 1893-1894, when a flood buried workings. The Young Mines Co., Ltd., headed by G.U. Young, acquired the property in 1910 and spent about 15 years exploring it. Produced 1893-1978. Extends into Maricopa County. Operators included Young Mines Co.; Goldfield Mines; E.L. Jones; E.H. Shumway; and Hebner & Funk.
Mineralization is hosted in rhyolite.
The geological setting is a pediment floored by coarse-textured granite, indurated conglomerate and granite breccia. The principal workings are in the vicinity of 2 Northward-trending, steeply Westward-dipping faults that outcrop about 300 feet apart. Tertiary volcanic fields are adjacent to this mine, both NW & SE of the drainage where it is located.
Width below the 426 foot level ranges from 16-36 feet, all worked for the 1240 foot length. Worked extensively to the 200 foot level before 1914. Sporadic operation until 1929. Recent cyanide leaching.
Workings include at least three shafts. The main shaft was sunk to the 1000 foot level. Additionally, thousands of feet of drifts were driven. Workings overall totalled 377.95 meters in length and 304.8 meters in depth. One named working is the 'Mormon stope.'
