Quartz vein breccia in rhyolite tuff from the base of the hill, low in the alteration cap in the southeast quadrant of the potassium anomaly, with a pervasive quartz-adularia-pyrite alteration of both groundmass and fragments, drusy quartz lining open space vugs, and late sericite overprint of adularia.
