Location: This placer gold occurrence is on Bull River, a tributary of the West Fork Chulitna River. The map site is in the NW1/4 of sec. 3, T. 20 S., and R. 10 W., of the Fairbanks Meridian. Placer activity has occurred downstream from the map site to the mouth of Costello Creek. This is location E-14 of Balen (1990: OFR 34-90).
Geology: The Bull River drainage area includes the Chulitna mineral district (for example, HE043), whose porphyry, skarn, and vein deposits all could be sources of placer gold. The richest of four samples of unspecified material collected by balen (1990: OFR 34-90) contained 1.5 ppm gold.
