A Pb-Ag-F-Ba-V-Mo-Zn-Au-Cu (As-Se-Be-Sb) mine located in the SW¼ sec. 24 & the North-central sec. 25, T4S, R19W (protracted). One of a group of claims on the Buckeye vein. Started about 1880.
Mineralization is irregular masses of partly oxidized argentiferous galena in a gangue of fluorite and calcite, up to 12 feet wide, and over some 2,000 feet in length, in a lensing vein along a fault zone with intersecting faults containing gouge and mineralization. Some wulfenite and associated vanadinite and vanadiferous mimetite occur in open cavities. Wall rocks are Mesozoic shale, limestone, and sandstone, strongly sericitized with some silicification and chloritization, cut by diorite porphyry dikes. Surface exposures are limited by the gravel cover of the rock pediment.
Workings include stopes worked from a series of shafts down to about 200 feet. Total production for the group would be some 20,000 tons or more of ore.
