A former underground Cu-Au-Pb prospect with underground workings located in sec. 13, T20S, R14E, just north of Littleshot Camp at an elevation of 6,275 feet, 9 miles W of Mt. Wrightson, about 13 airline miles NNW of Patagonia, on National Forest land. Discovered 1915. The Littleshot Mine could be the same as the Iron Cliff; can't tell from the literature.

Mineralization involves a 5 foot (1.52 meter) wide, iron-stained fault of shear zone in granite. The zone strikes ENE and dips 75ºNNW. It contains streaks of crushed rock or gouge-like material, which on the hanging wall side carries some pyrite and chalcopyrite with a fair amount of gold. On the opposite, or east side of the creek, a tunnel on the same ledge shows much pyrite and galena with a little pyrite and some arsenopyrite on the footwall. The host rocks include the Josephine CAnyon Diorite and the Madera Canyon Granodiorite. Ore control was the shear zone.

Regional trends include tilting and broad open folds in the south and extensive faulting in the north; thrust and normal faulting, shear zones.

Workings include a short tunnel.
