Geographic coordinates

Geographic coordinates: -147.53195, 64.95167 (WGS84)
Relative position The Tanana propsect is located in the SE1/4SW1/4 sec. 34, T. 2 N., R. 1 E., Fairbanks Meridian. The Tanana prospect is on the northeast side of Tungsten Gulch, a headwater tributary of First Chance Creek. It is about 3 miles east of the junction of the Steese and Elliott Highways at Fox. The prospect originally consisted of six scheelite lodes on five claims (Mertie, 1917). This prospect is included in locality 27 of Cobb (1972 [MF 410]).

Comments on the geologic information

  • Geologic Description = The Tanana prospect lies along the western edge of a Cretaceous granite porphyry. Gold and tungsten are found in auriferous quartz-scheelite veinlets that cut decomposed schist (Mertie, 1917). Berg and Cobb (1967, p. 220), reported that the scheelite deposits were found in tactite, silicified limestone, granite dikes, pegmatitic dikes, and in small quartz veins in schist. The schistosity strikes N. 30 E. and dips 35 NW.; one gold-quartz vein strikes N. 8 W. and dips 60 E. (Mertie, 1917). In 1942 and 1943, the only workings that could be found were a caved shaft and several small prospect pits. These workings revealed little geologic information because they had become filled with slope wash and were overgrown with vegetation (Byers, 1957).
