Exploration for possible buried economic Ernest Henry - Olympic Dam style IOCG mineralisation in the Nuckulla Hill area, 120 km north-east of Ceduna, was initiated following interpretation of new SAEI aeromagnetic and radiometric data. Regional calcrete sampling, coupled with soil and rock chip sampling, located several geochemically anomalous areas which were further defined by infill calcrete sampling and ground magnetics. First pass drilling, comprising RAB (249 holes, total 10,381 m) and aircore (62 holes, 577 m) returned encouraging results in the form of several gold, copper and zinc intersections (best, 7 m at 2.47 g/t Au in hole NHAC 26). A detailed low level aeromagnetic survey and various ground geophysical surveys were followed by further drilling at both previously drilled and new prospects, comprising diamond drilling (three holes for 491.5 m of core), plus RAB, reverse circulation and aircore methods (total 318 holes, aggregating 17,136 m). While no economic mineralisation was encountered, it is considered that those prospects along the Yarlbrinda Shear Zone showing significant gold mineralisation (e.g. Bimba prospect with a 24-36 m wide gold-bearing zone still open to the north) warrant further testing.
