A former small underground Ag-Au-Pb-Zn-Cu-Hg mine located in the center of sec. 25, T.20S., R.10E. on 1 patented claim and 20 unpatented claims, about 10 miles North of Arivaca. Discovered by early Spanish explorers about 1750. Produced 1856-1937. Closed 1884 to 1901. Mill operating in 1964.
Owned at times, or in part, by the Sonora Exploration & Mining Co.; Consolidated Arizona Mine & Milling Co.; Cerro Colorado Mining & Milling Co.; Udall; the Cerro Cristo Mines Co.; Arivaca Milling & Mining Co., Steinfeld; Baker; and, Snyder. NOTE: Coordinates updated February, 2008, using Garmin hand held GPS unit (at the shaft collar) by Ronald Deblois.
Mineralization is irregular, lensing, drusy, quartz-fissure vein with spotty sulfides and secondary minerals with minor barite, calcite and much iron oxide. The wall rock is an andesite porphyry complex. Ruby silver occurred in the oxidized zone. The veins are cut off by contact of sediments with basal andesite.
Workings include shaft workings. Operated from the 1770's to about 1937, producing some 3,000 tons of ore averaging about 100 oz. Ag/T, 0.1 oz. Au/T and minor amounts of Pb & Cu.
The richest ore on record ran over 12,000 oz. Ag per ton, the average ore mined in 1859 was 770 oz/t, the average of all ore mined since then has been about 225 oz/t. No significant quantities of ore were found below 350 feet.
The main shaft is flooded to 50 feet, other shafts in the vicinity are flooded, caved, or lagged at surface. Some ground on the Cerro Colorado claim might be unstable because large stopes are known to exist not far below the surface.
