A former surface and underground Mn mine located in sec. 33, T6S, R32E, 7.5 miles ESE of York on Willow Creek, on private land. Discovered in 1952 by L.A. Billingsley and Lewis Dean. First produced in 1953. Owned by L.A. Billingsley and Lewis Dean (1961).

Mineralization is lens-shaped ore bodies with Mn minerals occurring in lenses along two narrow parallel veins, 800 feet apart, that strike northward and dip steeply to the east (80E), and traverse volcanic rocks. The ore zone is 0.76 meters wide. The ore lenses are separated along both the strike and dip by barren intervals or by stringers of ore too narrow to mine. Surface oxidation present.

Area structures are steep northerly-trending zones of shearing and brecciation in volcanic rocks.
