Abstract: | This report describes the results of the third year of exploration for unconformity - related uranium deposits on the tenement. Five diamond drill holes were completed and detailed core analyses were carried out (XRD, PIMA, geochemistry, and downhole probing). Nimbuwah Complex granitoid forms basement in the area and is overlain by a variable thickness of Kombolgie formation sandstone. A minor zone of anomalous radioactivity associated with thin haematite vein was logged in one of the holes. Five Nano TEM traverses were done across a major structure and a test regional gravity line was completed in the west of the tenement. Nine airborne radiometric anomalies were followed up by field checking with a spectrometer. Most of the anomalies are related to surface concentrations of uranium in soil and laterite. None of the anomalies are caused by underlying uranium mineralisation. A regional stream sediment survey was undertaken to detect any uranium or gold anomalies not detected by the airborne radiometric surveys. The U results were generally not anomalous. Higher values tend to be related to areas of laterite developed on Nungbulgarri Volcanics, which are known to contain higher U values. One sample has the most anomalous U value (17ppm U) and requires field checking. The contact zone between the Nimbuwah Complex and the metasediments of the Cahill Formation is thought to occur close to the western border of the tenement and this zone is considered to be prospective for uranium mineralisation. The granitic rocks of the Nimbuwah Complex are thought to be less prospective. |
