FILE UNDER CONSTRUCTION - 1/16/20. Chet
A former Mn-V-Au-Ca occurrence/mine with traces of Au-V located in the NW¼SE¼NE¼ sec. 6, T11+N, R12W, G&SRM, 11 miles SE of Signal, on Bureau of Land Management administered land and/or private land (located claim). Discovered 1941. Owned by G. H. Lewis, J. Lewis and Mrs. B. Thompson (time frame unknown). Owned by the World Manganese Corporation of California (1973). Owned by the Homestake Mining Company, Colorado (1979). The USGS MRDS database stated accuracy for this locality is 1,000 meters.
Mineralization is a Mn deposit hosted in Pliocene conglomerate of the Artillery Formation. The ore body(ies) cover an area of 130 HA, strikes N25W and dips 62NE at a width of 2.44 meters, and consists of stringers and irregular nodules. Ore body No. 1 is a fissure vein, as is ore body No. 2. Ore body No. 3 is a shear zone. The primary mode of origin was contact metasomatism. Primary ore control was igneous activity. Wallrock alteration is slight (unknown, propylitic and advanced argillic, respectively). The Mn content decreases toward the vein hanging wall. Hosted in unnamed metamorphic units and undivided Green Gulch volcanics. Local rocks include Middle Miocene to Oligocene sedimentary rocks.
Workings include surface and underground openings . Workings at the site
