A former small underground Cu-Ag-Pb-Au-Fe-Be-Bi mine on a group which includes 32 patented and 56 unpatented claims, located in the West & South ½ sec. 16, SW ¼ sec. 15 and North ½ sec. 21, T.14S., R.27E, 2 miles NE of Dos Cabezas, 1½ miles SE of Dos Cabezas Peak, on private land. The location given is for the main Mascot shaft. Produced 1908-1967. Owned by Edwin I. Tout. Operated at times, or in part, by the Consolidated Copper Co.; Mascot Copper Co.; Southwest Metals Co.; Arivaca (Aztec) Mining Co.; American Smelting and Reduction Co; Central Copper Co; Pickrath and Irvin; Utex Exploration Co; and the Arivaca Mining Co.

Mineralization in the group is magnetite with base metal sulfides associated with epidote and other skarn minerals in irregular veins, massive bunches, and disseminations in badly fractured and faulted blocks of pyrometamorphosed Paleozoic limestone and Cretaceous shales and volcanics along, or close to, Laramide granitic intrusives and associated with dikes ranging from rhyolites to basalts. Various irregular bodies from 10 feet X 30 feet to 100 feet X 100 feet. Most of these bodies are eliptical in outline mostly in narrow veins, with associated disseminations. Ore control was E-W faulting, intersecting N-S diabase dikes.

Geology here is similar to other mines in the district as Cretaceous shale is pyrometamorphosed - more complex here because of various intrusive & volcanic rocks of Cretaceous-Paleozoic age. Similar E-W trending fissures to the rest of the district.

Local structures include fractured and faulted blocks of pyrometamorphosed Paleozoic limestone and Cretaceous shale and volcanics. Cretaceous-Paleozoic granitic intrusives at the Mascot shaft qand to the south. Dikes of diabase and rhyolite exist throughout the area. A fissure system is generally striking E-W; the overall Paleozoic strike is E-W, broken up by Cretaceous-Paleozoic faulting and intrusions.

Workings are extensive from long tunnels and shafts and total 13,411.2 meters in length and 182.88 meters deep. There are 2 shafts - the Elma and the Consolidated, plus the Mascot tunnel. Most workings are on the 200 foot and 400 foot levels. One tunnel is 2100 feet long, another is 1700 feet long. This description does not include the Elma Mine. Some 60,000 tons of ore were produced from the group intermittently from the early 1910's to the mid-1950's. The principal production occurred between 1908 and 1928.
