A former underground Au-Ag-Cu-Pb-Zn-Hg mine located 4 miles due south of the Yaeger Mine in the eastern foothills of the Black Hills at 5,800 feet of altitude on 13 claims (listed in the locality name string). Produced 1911-1950. NOTE: Also designated / known as: Patented claims MS 3013, Bucky O'Neil No. 2.
Mineralization is a vein deposit with a lenticular shaped ore body hosted in the Grapevine Gulch Formation. Country rock is principally comprised of Yavapai slates, fissile in places. An embayment of the main Bradshaw Granite area reaches up from the south nearly to the mine. Greenstone schists are in the vicinity. Ore control was fauklting and shearing. Ore concentration was oxidation at near surface. N alteration noted.
The vein strikes ENE and dips 60ºS. The gangue of the vein is chiefly massive white quartz, but includes some ankerite, and tetrahedrite, galena, and sphalerite irregularly distributed through it. The ore is partly oxidized, and cinnabar has been recognized in the oxide zone.
Area structures include foliation and transposed bedding in metamorphic rocks that trends N-S to N15W. Veins cut across foliation nearly at right angles, vein strikes ENE.
Workings include an inclined shaft 1,500 feet deep (1,053 feet on the dip of 60º), plus 2,000 feet of drifts.
