|Location and accuracy||This placer prospect is at an elevation of about 150 feet about midway along the unnamed creek flowing from Taku Lake to Taku Harbor. It is in the NW1/4SE1/4 section 6, T. 44 S., R. 70 E. of the Copper River Meridian. The location is accurate within 1/4 mile.|
Geologic descriptionThe Bum Cat placer prospect is in gravel overlying black phyllite and felsic phyllite that have been intruded by Cretaceous diorite and metagabbro (Redman and others, 1989). The phyllites contain disseminated and stratiform pyrrhotite and pyrite. The placer was discovered in 1905. The U.S. Bureau of Mines collected a 0.1-cubic-yard pan-concentrate sample of the gravel that contained 89.0 ppm gold and 12.0 ppm silver (Redman and others, 1989).
