A Fluorspar-Baryte-Pb-Zn-Cu-Ag occurrence located in sec. 29, T5S, R20E.

Mineralization is hosted in limestone and rhyolite.

A former surface and underground Pb-Ag-Zn-Cu-Mn-Au-Fe prospect/mine located on 37 unpatented claims within the group (1943), in sec. 29, T5S, R20E, 2 miles NE of Aravaipa, on National Forest land. Owned and operated by Mr. Frank Landsmen (1925).

Mineralization is a replacement deposit with an irregular ore body hosted in limestone, striking NW and dipping SW. Ore control was bedding, fractures of limestone, shattered rhyolite dikes and some mineralization in schist. An associated rock unit is quartz monzonite.

Area structures include fracturing transverse to bedding and the Landsman Camp Fault.

No ore has been shipped. Assay data: 1% Cu, a little Au.
