Location and accuracy | This occurrence is at an elevation of 5,200 feet approximately 1 mile east-southeast of the toe of McCallum Glacier. It is in the NW1/4SW1/4 section 12, T. 19 S., R. 11 E., Fairbanks Meridian. The occurrence is described by Hanson (1963, locality 12), and it corresponds to locality 26 in Cobb (1979 [OFR 79-238]) and locality S119 in table 2 of Nokelberg and others (1991). |
Geologic descriptionThis occurrence consists of chalcopyrite and galena in scattered areas of small quartz veins in metadacite tuff of the Slana Spur Formation of Pennsylvanian age (Hanson, 1963; Nokleberg and others, 1991). Samples of the mineralized quartz veins assayed 0.4 to 0.5 percent copper, 0.4 to 0.5 percent lead, and a trace of gold (Hanson, 1963). | |
