| Location and accuracy | 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. |
Geologic descriptionThis 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. | |
