Located in the Noatak Wilderness.
Location: This occurrences is at an elevation of about 600 feet, adjacent to Kivivik Creek about 5 miles above its confluence with the Noatak River. It is in section 24, T. 29 N., R. 14 W., of the Kateel River Meridian. Schmidt and Allegro (1988), location 4; field stations 84JS026A-D and 84PF070R.
Geology: At the occurrence, basalts of probable Jurassic age contain both disseminated chalcopyrite and pyrite, and pyrite and epidote in vesicles. A 30- by 40-meter area of red-orange-stained, pillow basalt contains pyrite, minor chalcopyrite and ochre. Magnetite occurs in the sediment of the stream draining this occurrence. A sample of pyrite contained 120 ppm Zn, 1 ppm Ag, 50 ppm Co, 300 ppm Cu, and 1000 ppm Mn. A sample from a heavily stained area contained 150 ppm Cu and 1000 ppm Mn. An ochre sample contained 110 ppm Zn and 200 ppm Cu. A sample of pyrite and epidote in vesicles contained 20 ppm As, 0.5 ppm Ag, and 1500 ppm Mn. A sample of chalcopyrite and pyrite in basalt contained 2 ppm Ag, 50 ppm Co and 500 ppm Cu (Schmidt and Allegro, 1988).
Workings: Area was visited and sampled by the U.S. Geological Survey (Schmidt and Allegro, 1988).
Age: Jurassic?
Alteration: Iron-oxide staining.
Commodities (Major) - Cu; (Minor) - Ag, Co, Mn, Zn
Development Status: None
Deposit Model: Basaltic copper (Cox and Singer, 1986; model 23).
