A former small surface and underground Fluorspar mine located in the center of sec. 34, T.17S., R.11E., on the NW flank of Gunsight Mountain. Owned at times, or in part, by Neptune; and, Fluxore.
Mineralization is ore in lenses and stringers in a shear zone along a Mesozoic quartz-mica-schist-granitic contact zone with associated aplite dikes. Lenses of fluorite 2 to 5 feet thick and perhaps 25 feet long and 25 feet deep, with minor calcite and silica. Fault breccia and gouge are present.
Workings include shaft, adits and pits. A few tons of 80% F ore may have been shipped in 1918-1920 and in the 1940's.
