A Cu-Zn occurrence/prospect with surface workings located in sec. 29, T13S, R12E.

Mineralization is brown-weathering garnet-calcite skarn with minor chalcopyrite, pyrite, & possibly sphalerite. The ore zone is 20 meters long and is hosted in Late Cretaceous latite. Some late white calcite veins carry minor chalcopyrite partly oxidized to tenorite(?) and malachite. Alteration is skarn. An associated rock unit is quartz monzonite.

Workings include a pit.
