Location: This unnamed occurrence is located on a southeast ridge about 200 meters from the summit of VABM Big (White Mountain), at an elevation of 3,100 feet (945 m) in the SE1/4 sec. 11, T. 24 N., R. 30 W., of the Seward Meridian. The location corresponds to prospect number 11 in Gilbert (1981); at station no. 79WG199.
Geology: This unnamed occurrence is a cinnabar-bearing breccia in a diabase dike that intrudes an unnamed algal limestone, a subdivision of the Nixon Fork subterrane (Gilbert, 1981; Wilson and others, 1998). The host dike trends east-west and dips steeply into the hillside. One sample of cinnabar-bearing breccia contained 214 ppm copper; mercury was not analyzed.
Workings: W.G. Gilbert found the occurrence during geologic mapping for the Alaska Division of Geological and Geophysical Surveys in 1979 (Gilbert, 1981). One sample of cinnabar-bearing breccia contained 214 ppm copper; mercury was not analyzed.
Reserves: None.
Commodities (Major) - Cu, Hg; (Minor) - Ag
Development Status: No
Deposit Model: Polymetallic vein (?) (Cox and Singer, 1986; model 22c).
