A group of W-Cu-Au-Fluorspar group of claims/prospect with surface and underground workings, located on 4 unpatented claims in the western part of sec. 5, T.16S., R.22E., across the ridge SE of the Tungsten King property. Discovered by J.J. Wien and A.H. Yeagley in 1931. Discovered by J.J. Wien & A.H. Yaegley. Owned by R.C. Wise (1940).

Mineralization includes disseminated scheelite with minor copper, gold and fluorite, associated with quartz fissure veins cutting the amphibolite unit of the Precambrian Pinal Schist and Abrigo Formation. At various places fissures parallel to the schistosity have been mineralized for widths of a few inches to a foot wide with quartz & tungsten minerals. Schist strikes NE dips steeply NW-ward. It is intruded about ½ mile (0.8 km) further South by granite. An associated rock unit is the Texas Canyon Quartz Monzonite.

Local structures include Tertiary block faulting trending NNW. Regionally, Late Cretaceous or Early Tertiary N- to NW-trending folds and thrust faults override to the NE.

Work includes a few shallow cuts, short adits & shallow shafts. Little or no production is noted.
