This occurrence is located within the Kobuk Valley National Park.
Location: The Hub prospect is at an elevation of about 1,850 feet in a small, north-facing valley about 3 miles east of the junction of Kanaktok Creek and the Salmon River. It is in section 5, T. 27 N., R.4 W., of the Kateel River Meridian. Schmidt and Allegro (1988), locations 34 and 35.
Geology: Bedrock at the Hub prospect is Devonian Skajit limestone and dolomite underlain by green phyllite. The Skajit limestone in this area is bounded on the east, west and north by lower Paleozoic schists and phyllites (Schmidt and Allegro, 1988). Some chalcopyrite and malachite occur in stream float in the upper reaches of the Salmon River. Follow-up work identified copper minerals in two outcrops about 1,000 feet apart. The minerals are in small, quartz-calcite veins that cut dolomite. Rock units strike N. 30 W. and dip 50 degrees W. A rock sample from the east side of the valley assayed 0.35% Cu and a rock sample from the west side assayed 1.1% Cu. Stream silt samples failed to detect anomalous copper. This may be attributed to the abundance of carbonate rocks in this area which may suppress chemical transport of metal ions (Degenhart and others, 1978).
Workings: Selected samples from the mineralized veins contained 1.1% Cu, 0.9-2.2 ppm Ag and 5 ppb Au (Degenhart and others, 1978).
Age: Devonian?
