Abstract

Geological mapping was continued and indicates that most of the faulting within the tenement is N-S trending. Most of the work, consisting of auger soil sampling, RAB drilling and diamond core drilling was concentrated within a biotite-garnet schist occurring as a wedge between amphibole biotite gneiss and porphyritic gravitoid. Some isolated spot high golds are indicated by the RAB drilling, i.e. RAB 313 at 98 ppg Au, whilst no significant uranium was intersected. The core holes intersected garnet rich biotite schists and gneisses, with some amphibolite units and pegmatoidal quartz-feldspar segregations. The radiometrics indicate that the lower counts indicate the amphibolite, while a high count of 700 cps corresponds to a pegmatitic segregation. The BIR 6 anomaly consisting of goethitic fine grained sandstone was further auger soil sampled and it is suggested that the uranium anomaly is due to enrichment by scavenging of radiometric elements from the gneiss to the ferricrete material. The BIR 4 anomaly has been extended by auger drilling. Stream sediment sampling has indicated three areas of anomalous labile uranium, with two of them clustered close to the Anuru Fault. Similarly the -80# samples indicate low gold anomalism close to this fault with values ranging from 6-22 ppb Au. Although an airborne Dighem survey was completed an assessment of the results still has to be made.
