Location: Prospect located above northeast bank of Grubstake Gulch, 4,500 ft southwest of VABM Home. Accurate within 2,500 ft. Locality 2 of Cobb (1972) and locality 2 of MacKevett and Holloway (1977).
Geology: According to Jasper (1962) a 17 inch quartz vein carrys pyrite, massive hematite, and bands of schist cuts Jurassic (?) quartz-muscovite-albite-chlorite (+/- garnet-biotite) pelitic schist. There is no visible gold, but high gold values were reported. Vein cuts across schistosity of country rock at orientations favorable to persistence of the vein structure over long distance, probably along a strongly developed shear zone.
Workings: Auger-hole sampling led to discovery of two caved open cuts which were reexcavated in 1962. Vein reported to have been traced in auger holes for several thousand feet. No gold visible, but high gold values reported (Jasper, 1962).
Age: Jurassic (?) or younger; vein cuts Jurassic ? schist.
