  • Silver and Copper Ore, Culberson County, Texas

    Silver and Copper Ore, Culberson County, Texas

    Location: listed as being from 1 mile north of Mica Tanks, in the Plato Verde Prospect, Van Horn Mountains County: Culberson County, Texas Minerals: assume disseminated Cerargyrite (synonym for Chlorargyrite) from the mine description text below. Chemical Formula: AgCl Crystal system: Isometric (typically clear when fresh with waxy, adamintine luster) Specimen size: 6 x 3 x 1.5 inches Specimen weight: 690 grams Collection Reference: TMM 1310 In the Jackson School of Geosciences Collection, at the University of Texas at Austin. Additional Information: Very specific information on this mine is found on the Supporting Text on the Geologic Quadrangle Map No. 23, Geology of the Van Horn Mountains, By Page C. Twiss, August 1959. "The Plata Verde mine, a mile northwest of the Mica Mine area along the western base of the Van Horn Mountains, contains small quantities of cerargyrite (horn silver). The mine was worked sporadically during the 1930's and 1940's. Most of the production occurred between 1936 and 1939, when 10,800 tons of ore were shipped to the El Paso smelter of American Smelting and Refining Company. The silicious silver chloride ore contained 9 to 26 ounces of silver and 0.23 to 0.46% copper, 68% silica, 13% alumina, 2% ferric iron oxide, 1% lime, 0.1% zinc, and 0.3% sulfur. The most recent exploratory work was done during 1951-1955, when a vertical shaft was sunk at the south end of the old workings (Peter T. Flawn, personal communication). According to Flawn, the mineralization is controlled by at least two major north trending gravity faults which border the shafts and inclines on the east and west. Small blebs of cerargyrite are concentrated along bedding planes and shear zones (parallel to the bedding) in the steeply dipping muscovite sandstone beds of the Permian Powwow conglomerate in the Wolfcamp Series."
