Mineralization is a lens-shaped orebody hosted in the Santa Fe formation. Alteration is sericitically altered andesite, potassic alteraton, and silicification. Mineralization occurs along or near the Frisco Mine Fault, in splays and rollovers, usually associated spatially with the replacement of Tertiary-age rhyolite sill/dike swarms.
