A former surface and underground W-Au mine located in the SW¼ sec. 24, T6N, R15W. Produced in 1951. Owned at times, or in part, by Brusco; Wood & Huthmacher; Aplington; Floreen & Associates; and, Fleming. Owned and operated by Mr. R. Wreggit (Transverse Mines Inc.) of Arizona (1982).
Mineralization is small grains and pods of scheelite in discontinuous quartz lenses in Mesozoic calcareous schist and in quartz fissure veins in Laramide granitic intrusive. The ore zone is 152.4 meters long, 61 meters wide, 46 meters thick, strikes N53E and dips 60S. There is strong fracturing and associated diabase dikes.
The strike and dip shown is only one of several different attitudes of the ore bodies. Other strike and dips include N50-56E, 50-70SE; N70-75E, 50-60SE; E, 40S; and N80W, 55SW.
This mine was worked from shafts, adits, pits, tunnels and open cuts from 1951 to the present (1978), producing some 1,200 tons of ore yielding about 600 units of WO3.
