Mineralization is a vein deposit with a tabular ore body. Ore control was faulting and shearing. Ore concentration was oxidation at near surface. Alteration was sericitization adjacent to some dikes. An associated rock unit is the Crazy Basin Monzonite and rhyolite porphyry dikes.
Area structures include Veins parallel to rhyolite dikes and foliation in Precambrian xenoliths (quartz-mica schist) that trends N40-50E.
