Location: The Columbia prospect is located in the NE1/4SE1/4 sec. 34, T. 2 N., R. 1 E., Fairbanks Meridian. This prospect is at an elevation of about 1770 feet on the south flank of Tungsten Hill at the head of Steele Creek. It is just southeast of the Spruce Hen group (FB101), approximately 3.2 miles east of the junction of the Steese and Elliott Highways. The prospect is included in locality 29 of Cobb (1972 [MF 410]).
Geology: The Columbia tungsten deposit consists of quartz-mica schist cut by quartz-scheelite stringers, under a hanging wall of porphyritic granite (Byers, 1957; Mertie, 1917). Workings in 1932 consisted of two adits, two shafts, a pit, and four trenches, all of which were caved by the 1950's (Byers, 1957).
