Following the farm-in of Anglo American Exploration to this tenement in March 2003, new activity has focussed on the rapid definition of drilling targets in a search for possible Archaean basement volcanic or sediment-hosted base metal massive sulphide deposits of Golden Grove or Kidd Creek type, and for potential mafic intrusive - related Ni or PGE mineralisation associated with the Polda Basin tectonic margin. No basement outcrop occurs in the 3 licence sub-areas; previous limited drilling indicates that it subcrops at depths of 20-100 m below surface. Initial ground TEM surveying performed by Anglo American at BHP Billiton's Pb-Zn and ?Mn mineralised Tooligie prospect failed to identify a conductive anomaly, but subsequent TEM work to follow-up a nearby existing EM anomaly at Oakdale prospect was successful in defining several conductive zones which were then investigated by drilling 6 RC holes totalling 1130 m. Concurrently, soil sampling was completed over two prominent magnetic features at Bramfield and Kappawanta that suggested the presence of buried mafic igneous intrusions. This work detected weak PGE/Ni anomalism in the Kappawanta area where regolith thickness is slight, but was unsuccessful over the Bramfield anomaly where the cover is moderately thick. Assaying of 297 basement rock samples recovered by the RC drilling returned anomalous base metal intercepts from all of the holes. The best result came from the depth interval 201-222 m in hole BLRC002, averaging 1.21% Zn, 0.32% Pb and 3.6 ppm Ag. Additional analyses of zinc-rich intervals in holes BLRC001, BLRC002 and BLRC006 for Au, Pt and Pd returned slightly elevated Au (46 ppb) from BLRC001, but gave no other significant precious metal values. One sample of galena from BLRC002 was selected for Pb isotope determination, but yielded somewhat equivocal results concerning the age of its crystallization. Petrological investigations of 46 basement rock samples selected from stored drill chips of previous RC drillholes have resulted in the recognition of a previously unknown volcano-sedimentary package comprising meta-komatiites, mafic volcanics and associated variably carbonaceous metasediments. The sequence, which is strongly weathered, has been interpreted to correlate with the Hall Bay Volcanics.
