A former small underground Pb-Ag-Zn-Cu-Au (Ba) mine located in the NW ¼ sec. 33, T.22S., R.16E., on the south vein of the Buffalo group, on National Forest land. Discovered 1897 by Sullivan & Powers. Produced 1898-1940. Owned at times, or in part, by Mr. Wieland (1898-1900); the Jefferson Mining Co.(1901-1902); and, the T.E. Mumme Mining Co., San Antonio, TX (circa 1910
Mineralization is a vein deposit with two E-W-trending veins about 600 feet apart, dipping NNE. Ore concentration was secondary enrichment. Country rock is a dark purple porphyritic andesite that is crushed and highly altered to soft vein material. The lode or vein dips NNE. The ore is almost entirely sulphide, although much of it is yellowish with carbonate and chloride of lead, and in places it is associated with a barite gangue. The copper occurs mostly in chalcocite.
Mineralization is narrow quartz-barite veins containing rich, oxidized lead-silver ore in the upper part and mixed argentiferous lead, zinc and copper sulfides in depth. Wall rocks are Cretaceous andesite and rhyolite volcanics.
Local structures include NW- and NE-trending fissures veins cutting thick-bedded, very fine-grained volcanics of Red Mountain and porphyritic to fine-grained, thin to very thick trachyandesite flows.
Tectonic elements are the Red Mountain and Corral Canyon Fault Blocks.
Workings total some 1,200 feet of openings, to a depth of 166 feet, comprised of a shaft, drifts, crosscuts, and stopes on 2 levels. Small production reported.
