Location: This occurrence is at an approximate elevation of 2,850 feet on the east side of the Richardson Highway near Phelan Creek. It is in the SE1/4NE1/4 section 5, T. 19 S., R. 11 E., Fairbanks Meridian. This location is accurate within a quarter-mile. The occurrence corresponds to locality S110 in table 2 of Nokelberg and others (1991).
Geology: At this location, quartz veins in joints cut meta-andesite agglomerate of the Slana Spur Formation of Pennsylvanian age (Nokleberg and others, 1991). A composite chip sample of quartz containing chalcopyrite, malachite, and bornite contained 10,000 parts per million (ppm) copper and 20 ppm silver.
Age: Pennsylvanian or younger.
Alteration: Oxidation of copper minerals.
Commodities (Major) - Ag, Cu
Development Status: No
