A former underground Pb-Ag-F-Ba-V-Mo-Zn-Au-Cu (As-Se-Be-Sb) mine located in the center of E½ sec. 36, T4S, R19E, and sec. 1 & East-central sec. 12, T5S, R19W (protracted), and extend southward from the Union shaft, 6 miles SW of Castle Dome Peak, on federal land. Owned at times, or in part, by Mrs. E. Lincoln (1933); Mr. A.P. Modesti, Laguna and Hudson (before 1900).
Mineralization is a vein deposit with spotty bunches and pockets of partly oxidized, argentiferous galena in a gangue of calcite, fluorite, and minor barite, with copper staining, in lensing, 1- to 8-foot wide veins along fissures at the contacts of Mesozoic shale and limestone with diorite porphyry dikes. The ore zone is 60.96 meters depth to bottom. Wall rocks show strong silicification and sericitization. Ore shoots extend downward about 200 feet. Ore control was along fissures at shale and limestone contacts with diorite porphyry dikes. The associated rock unit is the Kofa volcanics. Tectonics included block faulting. croppings partially covered by surface gravels overburden.
Workings include stoping operations from shafts in the late 1800's and early 1900's. Total estimated and recorded production would be some 965 to 1,400 tons of ore averaging about 43% Pb and 38 oz. Ag/T. Some fluorspar was also shipped. Fill and dumps were reworked in the late 1940's.
