Exploration in the Wanilla - Cummins area searching for economic accumulations of heavy minerals in Eocene sands comprised 2 phases of aircore drilling (167 holes, total 4049 m). A resulting drill intersection yielded a 0.72% heavy-mineral concentrate containing up to 40% ilmenite, 23% leucoxene, 21% zircon, 6% rutile and 2% monazite. The best mineral sands grade obtained was 3 m at 1.41% TiO2 and 0.15% ZrO2. Although this work has disclosed a new heavy mineral sands province with favourable mineralogy, no sizeable reworked marine deposits were identified, and the disproving of the original exploration concept has downgraded the area's potential. A subsequent switch of objective to finding possible Proterozoic Broken Hill - style stratiform metallic ore occurrences involved undertaking soil, rock chip and BLEG stream sediment sampling, ground magnetics, and aircore drilling (97 holes, total 3250 m), which disclosed low-order Pb/Zn and Au/As anomalies in Hutchison Group BIF, amphibolites, graphitic schist and calc-silicate rocks beneath shallow lateritic cover.
