|Location and accuracy||This prospect is at an elevation of about 4,000 feet in the headwaters of Virginia Creek, a tributary of the Wood River. The site is in sec. 32, T.12 S., R. 1 W., of the Fairbanks Meridian. The location is accurate to within one-quarter mile.|
Geologic descriptionThis deposit is a steeply-dipping stratabound massive sulfide horizon up to 13.1 feet thick in pelite and quartzite of the lower Paleozoic to possibly Upper Precambrian Birch Creek Schist (Wilson and others, 1998). The metasediments are cut by a lower Tertiary to Cretaceous intrusive stock on the southeastern boundary of the prospect area. The sulfide minerals are chalcopyrite, galena, pyrrhotite, and sphalerite. At least six drill holes have tested the deposit. Samples contain up to 0.53% copper, 1.89% lead, 6.51% zinc, 185.1 grams of silver per ton and 0.38 grams of gold per ton (www.grayd.com, 1999).
