Location: Located above Shungnak River on Bismark Mountain in T. 19 N., R. 7 E., Kateel River Meridian. Shown as locality 18 in Mayfield and Grybeck (1978) and accurate to within 1000 ft. (300 m).
Geology: Network of low grade cross-and slip-fiber chrysotile veinlets 0.5-2.0 in. (1-4 cm) wide in area of serpentine float 800 ft. (244 m) long, several hundred feet (60 m) wide and up to 8 ft. (2.5 m) deep. Nearby magnesite veinlets and asbestos as well as residual boulders of nephrite occurr over a wide area of serpentinized ultramafic rocks cutting schist (Heide and others, 1949, p.16-18).
Workings: 4 or 5 surface trenches dug by USBM circa WW II. Small test shipment made during World War ll but no production (Anderson, 1945, p. 19-20).
