Location: This occurrence is on the east side of an unnamed east fork of Whistler Creek at an elevation of 4,000 feet. The occurrence is about 750 feet north of the center of section 4, T. 14 S., R. 5 E., Fairbanks Meridian; the location is probably accurate to about one-quarter mile. The site corresponds to locality N4 in table 2 of Nokleberg and others (1991).
Geology: This occurrence consists of pyritic quartz-white mica-chlorite schist of early to mid-Paleozoic age (Nokleberg and Aleinikoff, 1985; Nokleberg and others, 1991; Lange and others, 1993). The schist is quartz veined. Grab sample 80NK010B of the pyritic schist contained 250 parts per million lead (Nokleberg and others, 1991).
Workings: There are no workings at the site. Reconnaissance samples of pyritic schist contained 250 parts per million lead (Nokleberg and others, 1991).
Age: The pyrite may be a primary constituent of the early to middle Paleozoic schist host rock.
