Last Resort Mine; Doyle-Smith claims
A former surface Mn mine located in the NE¼ sec. 36, T10N, R14W, GSRM, 9.6 km (6.0 miles) SW of the Alamo Lake Dam, and about 15 miles from Artillery Peak. Started in the mid-1950's and closed in the late 1950's. Owned at times, or in part, by the Doyle Brothers; Stovall & Associates; Brown, Maddox, Dasco Mines Corp. MRDS database stated accuracy for this location is 100 meters.
Mineralization is pyrolusite, psilomelane, and manganite, with brecciated igneous and sedimentary rock fragments and calcite, in Tertiary sandy sediments, similar to the Artillery Peak area, that unconformably underlie Precambrian gneiss. Strong fault and shear zones are present. Manganese mineralization varies greatly in thickness. The best ore is closely associated with strong shearing and close to a thrust fault plane. Tertiary conglomerate with manganiferous lenses that range from 3 to 7 feet thick. The conglomerate consists of quartz & granite boulders between 2 and 8 inches in diameter. Manganese oxides coat the surface of the boulders and form part of the conglomerate matrix. Local rocks include Middle Miocene to Oligocene sedimentary rocks.
Workings include surface openings comprised of an open pit. Production was some 70,000 long tons of 15-16% Mn ore in the late 1950's. Some 1,460 long tons of 40% Mn ore was produced in 1958 by concentration.
