A former small underground Au-Pb-Ag-Cu mine located in the SE ¼ sec. 21 and the SW ¼ sec. 20, T.14S., R.27E. (Dos Cabezas 7.5 minute topo map), immediately East of the Dives group and about 2½ miles North of Dos Cabezas village. Discovered and started in 1878. Reopened in 1915-1917 timeframe. Ultimately closed 1935. Owned at times, or in part, by Mrs. J.H. Huntsman of Tucson, and the Dos Cabezas Gold Ridge Mining Co. (1917- ); and, the Chicago and Arizona Copper Co.. William Dorsey operated the mine with 12 to 15 sub-lessees (1933-1934). NOTE: Alternate coordinates provided: 31.93028N, 109.59028W (Latitude varies greatly!).
Mineralization is scattered bunches and disseminations of auriferous galena, pyrite and chalcopyrite, plus oxidized copper minerals, in bands of coarse-textured quartz along a major fault and parallel shears separating blocks of Cretaceous graphitic shale and pyrometamorphosed Paleozoic (Bisbee group)limestone to the north from Precambrian granitic rocks (Rapakivi Quartz Monzonite) to the south. The Cretaceous beds strike E-W and dip 60 or more degrees N.
Workings include numerous shaft and adit openings. Some 1,000 or more tons of ore were produced intermittently in the 1880's and 1890's and from 1915 to 1936.
