A former underground Pb-Ag-F-Ba-V-Mo-Zn-Au-Cu (As-Se-Be-Sb) mine group located in SW¼ sec. 24 & the North-central sec. 25, T4S, R19W (protracted), on the W side of the Castle Dome Mountains; about 3 miles N of Castle Dome Mine, 4 miles SW of Castle Dome Peak, on federal land. Started in 1863. Owned at times, or in part, by Castle Dome Mining & Smelting Co., Gondolfo & Sanquinetti, Mrs. Elizabeth De Luce, Castle Dome Mining Co., Hull Mines, Rialto Co., Joplin Lead Co., Wall, Desert Lead Co., and Taylor. Owned by Mr. G. Hull (1933). The Rialto-Hull group is considered as part of the Castle Dome Mine group.

Mineralization is irregular masses of partly oxidized argentiferous galena in a gangue of fluorite and calcite, up to 12 feet (3.66 meters) wide, and over some 2,000 feet (609.6 meters) in length, in a lensing vein along a fault zone with intersecting faults containing gouge and mineralization. The ore zone has a depth to bottom of 91.44 meters, strikes N30W, and dips 70NE. 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. A related rock unit is the Kofa volcanics. Tectonic influences include basin and range block faulting. Ore control was the fault zone containing intersecting faults and gouge. Ore concentration was supergene enrichment.

The vein follows a fault zone in shale. Green, purple, and rose coloured fluorite is associated with calcite, baryte, galena and wulfenite in veins where metasediments have been intruded by rhyolite and diorite porphyry. Veins split and branch but are traceable for as much as 4000 feet. The fluorspar ore is usually < 5 feet thick.

Workings include stopes worked from a series of shafts down to about 200 feet, and total 518.16 meters in length. Most ore was mined prior to 1900 but fill & dumps were worked to 1960. Total production for the group would be some 20,000 tons or more of ore; about 8333 tons of ore averaging 5% Pb, 2% Cu, 1.96% oz/t Ag, minor Au.
