|Location and accuracy||This occurrence of placer gold is on an unnamed southeast-flowing tributary of the East Fork Chulitna River. The placer extends upstream from the map site, which is in the SE1/4 of sec. 19, T. 20 S., R. 7 W., of the Fairbanks Meridian. This is location D-3 of Balen (1990: OFR 34-90).|
Geologic descriptionThis tributary drains an area underlain by Lower Cretaceous or Upper Jurassic turbidites and Lower Tertiary volcanic rocks (Wilson and others, 1998). Of 13 placer samples collected the highest values were 360 ppb gold and 110 ppm tin (Balen, 1990: OFR 34-90). The source of the placer gold and tin is unknown.
