A former small surface and underground Cu-Ag-Au mine located in the SW ΒΌ sec. 28, T.12S., R.6W. (Ajo 15 minute topo map), 2 miles SW od Ajo on private land. Two patented, 21 unpatented claims adjoining the New Cornelia Mine property. Idle in 1943. Owned at times, or in part, by the Cardigan Copper Co.; and, Childs, et al.
Mineralization is narrow, irregular veins containing quartz, specularite, epidote, barite, ankerite, and spotty copper oxides, carbonates and sulfides in altered Cretaceous volcanics near a major fault zone.
Workings include shallow shaft and surface operations. The main shaft is over 100 feet deep at 70 drgrees of incline; numerous shafts 15 to 50 feet deep; A pit was 45 feet by 10 feet by 10 feet in 1918. Some 1,000 tons of hand-picked copper ore were produced intermittently from 1917 through 1926. Ore averaged about 4% Cu and 10 oz. Ag/T.
