|Location and accuracy||Located on spur ridge about 2 mi 3.2 km) west-southwest of VABM Cone, at locality 2 of Barker (1981, p. 25); located to within 3000 ft (915 m).|
Geologic descriptionMineralized (disseminated chalcopyrite and galena) float in phyllites occurs in an east-northeast trending belt 50-150 ft (15-46 m) wide by 1200 ft (366 m) long. Bedrock in the area is black phyllite and interbedded green and maroon argillite of Paleozoic? age locally intruded by porphyritic rhyolite sills and dikes, and mafic dikes (Barker, 1981, p. 64-68).
