Location and accuracy This occurrence is at an elevation of 2,700 feet at the north end of Rainbow Ridge about 1.1 miles northeast of the 'Miller Mine' on the Richardson Highway (Hanson, 1963, p. 71). It is near the foot of a steep canyon in the NE1/4NE1/4 section 19, T. 18 S., R. 11 E., Fairbanks Meridian. This location corresponds to locality S101 of table 2 in Nokleberg and others (1991) and to locality 16 of Cobb (1979 [OFR 79-238]).

Geologic setting

Geologic description

At this locality disseminated pyrite and chalcopyrite occur in graywacke and conglomerate with pyrite and chalcopyrite (Hanson, 1963, p. 71). The mineralized rock is iron stained and is exposed over a few hundred square feet. Samples of the mineralized conglomerate assayed 0.12 ounce of gold per ton (Hanson, 1963). The host rocks are part of the Slana Spur Formation of Pennsylvanian age (Nokleberg and others, 1991).
