Mineralization is spotty, disseminated sphalerite, galena, and chalcopyrite, partly oxidized, in narrow pyrometasomatic lenses of Permian Naco Group limetone along the contact with Laramide granodiorite.
Workings include relatively shallow openings. Produced some 100 tons of ore averaging about 12% Zn, 7% Pb, 0.7% Cu, and 9 oz. Ag/T.
