A former small surface and underground Cu-Ag mine group located in the NW ΒΌ sec. 21, T.17S., R.16E. (Empire Mts 15 minute topo map), 25 miles SE of Tucson. Produced in the mid 1950's. Owned at times, or in part, by Cardiello & Serasio; and the Aricu Mining Co.
Mineralization is spotty secondary copper minerals and sulfides with sooty magnetite along fault and fracture intersections in a silicified, garnetized, and epidotized Paleozoic limestone block engulfed in Laramide intrusive. Ore control was fault and fracture intersections.
Workings include tunnels, shafts, and open cuts. Some 150 tons of ore averaging about 3.5% Cu and 2 oz. Ag/T were produced in the mid-1950's.
