A group of 26 Cu-U claims/occurrence with surface and underground workings located in sec. 34, T17S, R11E, on private land. Owned by Richard Siebeck, Oliver Palmer and Roy Gill (1956).
Mineralization is a vein deposit with ore in lenses and along the fault, hosted in quartz monzonite. The ore zone is 304.8 meters long, 0.91 meters thick, strikes N57E and dips 80E. Alteration includes hematitic and kaolinization. Radioactivity: background 0.02 mr/hr, max 6.0 mr/hr.
Workings include one drift and location pits. The tunnel is 16.76 meters long.
