A former small surface and underground W-Fluorspar-Cu-Pb-Zn mine located in the southern central portion of sec. 1, T.16S., R.22E, 2¼ miles SSE of the town of Johnson, on private land.
Mineralization is a vein deposit with hübnerite, scheelite, fluorite, and minor base metal sulfides in a large sinuous quartz vein in altered Laramide Texas Canyon Quartz Monzonite. The ore zone is 1,219.2 meters long and 1.22 meters thick, strikes N70E and dips 43 to 60S. Ore control was quartz veins. The average tungsten content is low. The thickest and richest parts of the vein are at bends. The vein pinches out locally. Another vein is 1,800 feet long, and as much as 6 feet thick. It strikes N45E and dips 65SE. At the NE part of the vein, small en echelon veins strike N10 TO 20E; at the SW part of the vein, small veins striking N45E appear.
Local structures include Tertiary block faulting trending NW. Regionally, Late Cretaceous or Early Tertiary N- to NW-trending folds and thrust faults override to the NE.
Workings include surface workings (pits) and 4 inclined shafts to a depth of 30.48 meters. A small tonnage of tungsten ore was produced during 1914-1917.
