A former surface and underground U-Cu mine located on 21 claims in the SW¼ sec. 24, T5N, R14E, and in sec. 19, T5N, R15E, 500 feet above the floor of Bull Canyon, about 4½ miles E of Asbestos Point (Asbestos Peak), on National Forest land. Owned by the Arizona Globe Uranium Co., Globe.
Mineralization is the Sue deposit, a vein deposit with a linear ore body hosted in the Dripping Springs Quartzite-Upper Member. Host rocks for the deposit are medium- to light-gray siltstone and very fine-grained arkose quartzite with inter-stratified lenses of white to grayish-pink, fine-grained quartzite. Stylolites are abundant in the finer-grained rocks and locally between the siltstone and fine-grained quartzite. Much host rock is bleached and strongly iron-stained, especially near fractures and in certain stratigraphic intervals. The ore zone is about 3 feet thick and host strata dips about 5 degrees SW. An associated rock unit is diabase.
At the surface, the ore appears to be low grade rim concentrations of secondary uranium minerals along the outcrop of favorable strata. Underground the ore is coincident with obscure, discontinuous or en echelon fractures trending north-northeasterly.
Workings include nearly 800 feet of workings. The east adit is 195 feet long and the west adit is 115 feet long, plus a 210 foot long drift. Workings achieved a depth of 59.44 meters.
