A group of 3 unpatented tungsten claims and former surface and underground mine located in the SE ¼ T.9N., R.2W., on the saddle between Walker and Banty Creeks, about 2 miles SW of Silver Mountain at about 3,500 feet of altitude. Found about 1940 by W.L. Palmer and G.A. Westerdahl. Owned by W.L. Palmer & G.A. Westerdahl.

Mineralization is a lenticular ore body hosted in the prevailing Precabrian Yavapai Schist, intruded on the South by granite and invaded by large sill-like bodies of tourmaline-bearing pegmatite.

In the vicinity of the claims a prominent belt of granular, dark-colored schist a few hundred feet wide strikes generally NE-ward and dips about 60ºNW. It strongly affects a compass needle. This belt is cut at right angles by a fault zone about 2 feet wide marked by strong gouge in the hanging wall, which dips 80ºSE. Walls show some seritization.

Workings include a pit that is 25 feet (8 meters) long and 20 feet (6 meters) deep.
