A Pb-Ag-F-Ba-V-Mo-Zn-Au-Cu (As-Se-Be-Sb) mine. Started before 1880 and owned in part, or at times by the Castle Dome Mining & Smelting Co., New York; Mrs. William DeLuce (1899); and, Dr. A. G. Hull (1933). Additional names: Lola claim.
Mineralization is the Buckeye vein. The Railroad portion of the vein is 12 feet thick. 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 5 shafts at 45, 60, 85, 300 & 470 feet deep, respectively. Stopes were worked from a shaft at 250 feet deep (1881). Connected to the Surprise claim (Pocahontas Mine) by a 200 foot long drift. Total production for the group would be some 20,000 tons or more of ore.
