Mineralization is hosted in andesite, sedimentary breccia and tuff (volcanic breccia [agglomerate]). The ore body is 0.1 meters thick. Psilomelane stringers 1 to 4 inches thick in a crystal lithic andesitic tuff and breccia (dacite ?). General trend of the stringers is NW-SE, dipping SW. Some manganite may be present. Local rocks include Tertiary pyroclastic and volcanic mudflow deposits, unit 9 (Cascade Range).
Workings include surface and underground openings comprised of a 15 foot deep, 28 foot long, 4 foot wide cut with a shaft started at the end. Another cut is caved. There is also a 15 foot tunnel.
