The occurrence is in Denali National Park and Preserve.
Location: The Quartz lode No. 1 occurrence is at an elevation of about 1500 feet on the west side of the canyon of Chitsia Creek. It is about 2 miles above the mouth of the canyon, near the center of section 18, T. 11 S., R. 14 W., Fairbanks Meridian. The location is probably accurate within 1500 feet. The occurrence is number 73 of Bundtzen, Smith, and Tosdal (1976), 32 of MacKevett and Holloway (1977), 53 of Hawley and Associates (1978), and 82 of Bundtzen (1981), and corresponds to an unnamed vein in Cobb (1980 [OFR 80-363]).
Geology: This deposit consists of a chalcopyrite- and galena-bearing quartz vein that cuts metarhyolite porphyry of the Upper Devonian and Mississippian Totatlanika Formation (Bundtzen, 1981). The vein is 2- to 3-feet thick, strikes about N 40 W, and dips 70 W. Rocks at the occurrence are coated with malachite. Grab samples assayed 0.58-1 percent copper, as much as 210 ppm lead, 51 ppm molybdenum, and 0.24 ounce of silver per ton. Bundtzen (1981) suggests that molybdenum is a characteristic trace element in deposits affiliated with the metarhyolite. The age of the vein is uncertain. It may be as old as Devonian or Mississippian, the depositional age of the Totatlanika Formation, or as young as Eocene (see MM091).
Workings: The vein was discovered, mapped, and sampled by Bundtzen, Smith, and Tosdal (1976). There are no significant workings.
Age: The age of the vein is uncertain. It may be as old as Devonian or Mississippian, the depositional age of the Totatlanika Formation, or as young as Eocene (see MM091).
Alteration: Oxidation of copper mineral.
