A former small surface Mn mine located in South-central sec. 16, T.23S., R.24E, approximately 1 mile W of Lowell. Owned at times, or in part, by the Calumet & Arizona Mining Co. and the Phelps Dodge Corp.

Mineralization is disconnected bodies of hard manganese oxides and manganiferous calcite along fissure zones cutting Pennsylvanian-Permian Naco Group limestone.

Workings are surface openings. Three open cuts and a short adit. The largest open cut was about 150 feet long, 5 to 8 feet wide and 10 feet deep. Drifts run 20 feet south and 16 feet north on the second open cut, which was 15 feet deep and 50 feet long. 2 to 4 feet of manganese mineralization is exposed in the faces of the drifts. A few hundred tons of manganese oxide were produced in 1917-1918.
