RB 60/00054 Geological report no. 1 on the Oolanta anomaly, Hd Stokes, southern Eyre Peninsula (Cummins and Tumby 1-mile sheets).

Author: Robinson, W.B.

10 miles north-west of Tumby Bay, a syncline of jaspilite, with a shallow southerly plunge, could contain 8-13 million tons of magnetic iron ore per vertical 100 feet. Unweathered jaspilite with magnetite occurs. Assessment of the potential of the iron occurrence is hampered by its poor exposure. An aeromagnetic survey shows peaks of 2000 gammas above background over the nose of the syncline, with diminishing values along the flanks. Two diamond drillholes totalling approximately 750 feet are proposed to test the flanks of the structure.
