A former underground manganese mine located on 5 claims, in sec. 20, T7S, R16E, about 8½ miles NNW of Mammoth, 3 miles West of the San Pedro River and 15 miles South of Winkleman at 3,300 feet of altitude, on private land. Started in early 1918. Owned by J.W. Norton.
Mineralization is a vein of coarse-grained calcite which projects in places a foot or two above decomposed granite country rock. The vein is 76.2 meters long, 0.61 meters wide, strikes N45W and dips 45SW. It can be traced continuously for 350 feet and its greatest width is 10 feet. Ore occurs principally in the hanging wall side of the vein & the ore shoot is about 250 feet long and 2 feet wide. The ore occurs mainly in the hanging wall side of the vein. The psilomelane exhibits a concentric structure.
Workings include 2 prospect holes (the largest is about 25 feet long by 6 feet deep). No production record.
Assay data: 25 to 40% Mn, 4% silica.
