Location and accuracy Location plotted is for sample localities 1 and 18 of Barker (1981, p. 122) on unnamed southeast flowing tributary of Coleen River, about 6 mi (9.6 km) south of Boulder Creek junction; located to within 1000 ft (305 m).

Geologic setting

Geologic description

Massive white to gray barite occurs in creek float. Minor Cu and Zn oxides coatings occur on chert float. Nearby outcrops are interlayered gabbro, argillite and chert (Christian River sequence of Brosge and Reiser, 1969) and black shale (Triassic Shublik Fm.) with abundant Fe stain, quartz veins and iron nodules (Barker, 1981, p. 121).

Production and reserves

Workings or exploration Mineralized chert sample contains 0.03% Cu, and 0.077% Zn. Soils contain up to 460 ppm Cu. Heavy mineral concentrate contained more than 10,000 ppm vanadium, but no gold. Mineralization extends in a band 1.5 mi (2.4 km) northeast and 1 mi (1.6 km) southeast (Barker, 1981, p. 121).
