Mineralization is hosted in Pliocene andesite. This deposit is in the same alteration - silicification zone as the Morning Star, Curtz & Georgiana Mines. NES. The mineralized vein is probably associated with the shear zone. Local rocks include Tertiary pyroclastic and volcanic mudflow deposits, unit 9 (Cascade Range).

Workings include underground openings comprised of 2 drift adits at 300 and 200 feet long. A 100 foot deep shaft is located near the top of the hill. All workings were inaccessible by 1969. The lower adit is near the Mogul Canyon floor.
