|Location and accuracy||This occurrence is at an elevation of 4,700 feet west of the head of North Fork Rainy Creek. It is in the SW1/4SW1/4 section 13, T. 18 S., R. 9 E., Fairbanks Meridian. It corresponds to locality 17 of Rose (1965) and to locality S59 in table 2 of Nokleberg and others (1991).|
Geologic descriptionAt this occurrence, chalcopyrite and secondary copper minerals are in a shear zone that strikes N70E (Rose, 1965). The mineralized zone is about 6.5 feet wide by 10 feet long and is hosted in pyrite-altered dacite porphyry that intrudes the Slana Spur Formation of Pennsylvanian age (Nokleberg and others, 1991).
