A former small underground Cu-Ag-Pb-Zn-Mo-Au-Baryte-Fluorspar mine located in the NE ΒΌ sec. 4 T.12S., R.8E. (Vaca Hills 15 minute topo map), 2Β½ miles NW of Silver Bell. First produced 1865. Owned at times, or in part, by the Huachuca Mining & Smelting Co.; Pima County Mining & Smelting Co.; Silver Bell Mining Co.; Albert Steinfeld Co.; Imperial Copper Co.; and the American Smelting & Refining Co. (ASARCO).
Mineralization is copper, and minor lead and zinc, carbonates and sulfides in fissure veins and irregular disseminations in pyrometasomatic deposits in garnetized or altered Paleozoic limestone blocks engulfed in Laramide dacite porphyry and monzonite intrusives, along a major fault zone. Alteration was hydrothermal metasomatism. Tactite present.
Local structures include a major fault zone.
Prospected and worked from the 1870's to 1931 as an underground mine. Over 1,000,000 tons of ore were produced, averaging better than 3% Cu and about 1 oz. Ag/T with minor Pb, Zn & Au.
