Mineralization is disconnected and irregular bodies of argentiferous pyrolusite and wad and oxidized base metal sulfides along fracture zones or in pockets in exotic blocks of Paleozoic limestone in Triassic-Jurassic volcanics.
Local structures include NW-trending bedding, near the intersection with a NE-trending normal fault.
Workings include a shaft, pit and tunnel(s). Some 20 tons of manganese ore and 383 tons of base metal ore were produced in 1917.
