Location: At milepost 16.2 of the Steese Highway, a mining road follows Steamboat Creek to the northwest. Dozer cuts of the Lundgren-Rowley prospect are located 0.4 miles up the road on the east side of the road; NW1/4SE1/4 sec. 10, T. 2 N., R. 1 E., of the Fairbanks Meridian.
Geology: Samples of quartz diorite with scheelite contained from 0.045 to 0.35% tungsten (Conwell, 1972). Petrographic examination of the quartz diorite identified the following minerals associated with the tungsten ore: quartz, plagioclase, potassium feldspar, biotite, and amphibole. No significant gold or silver was found upon atomic absorption analysis (0.002 to 0.008 ounces of gold per ton; 0.015 to 0.02 ounces of silver per ton) (Conwell, 1972).
Workings: Surface samples were taken in the early 1970's from bedrock exposed by a dozer trench (Conwell, 1972).
