Geographic coordinates

Geographic coordinates: -148.92789, 64.08268 (WGS84)
Relative position This unnamed prospect is located in sec. 4, T. 10 S., R. 7 W., Fairbanks Meridian. Although this occurrence is called Spruce Creek, Cobb plotted it at the head of Rex Creek, just west of Spruce Creek. The coordinates reflect Cobb's location; it is unclear if this location is accurate, and this occurrence may be a mile or more away. The occurrence is locality 38 of Cobb (1972 [MF 410]).

Comments on the geologic information

  • Geologic Description = Bedrock in the area is gray quartz-orthoclase-sericite schist and augen gneiss of the California Creek Member of the Totalanika Schist (Wahrhaftig, 1970 [GQ-810]). Berg and Cobb (1967, p. 202-203) reported a few gold-bearing lodes and small jamesonite-bearing veins. Samples from an antimony-bearing vein contained 0.44 ounce of gold per ton and 5.4 ounces of silver per ton (Joesting, 1943 [ATDM Pamph. 2, p. 14]).
