The DeSoto Mine was discovered 1890. Produced Cu-W-Ag-Au-Pb-Zn-Fe from 1890-1972. Workings include a main tunnel 600 feet below the outcrop; a total of 4 tunnels (1928). Production was 180,000 tons of ore averaging 3.75% Cu & 1 oz. Ag/T plus 0.02 oz. Au/T.
The Swatstika Mine was discovered in 1874 by T.N. Alexander, W. Cole, E.G. Peck, and C.C. Bean. Its name comes from the pattern of tunnels if viewed from a height as the tunnels are in the shape of a swatstika. Main production period was 1907-1940. Workings include shafts (125 feet deep), drifts and tunnels. Workings include several shafts and drifts plus a tunnel nearly 400 feet long. The shaft is 400 feet deep. Production was some $40,000 of Ag (1883)(period values), and 600,000 oz. Ag (1910-1915). Production was $480,000 of silver (1875-1908)(period values). Ore assayed at 113 oz. Ag/T. This info referenced from Mindat.org. This ATV trip was a great ride and not too difficult to get to. The Desoto Mine is extremely dangerous as much of the over reaching rocks and dirt have fallen into the main area of the mine shafts creating a 60 degree incline into the shafts. Dropping a rock into the 600 ft. shafts generated sounds for up to a minute. Be very careful near this mine.
