|Location and accuracy||The Silver Kitty prospect is at an elevation of about 5,500 feet, above the north head of Christy Creek. The site is in the SE1/4 of sec. 23, T. 20 S., R. 12 W., of the Fairbanks Meridian. Accuracy of location is within 0.25 miles. This is locality 9-12 of Hawley and others (1969); and locality 27 of Hawley and Clark (1974).|
Geologic descriptionThe Silver Kitty prospect is hosted in Lower Jurassic and Upper Triassic redbed sandstone and argillite. An Upper Cretaceous quartz diorite porphyritic stock cuts the argillite. The prospect consists of chalcopyrite- and sphalerite-bearing skarn adjacent to the stock (Hawley and Clark, 1974), along with some disseminated sulfides. Samples contain 0.4 ounce of gold per ton and 1.8% copper (Balen, 1990: OFR 34-90).
