Annual report for EL 25850 Barry Creek, period ending 22 October 2008

Abstract

The NuPower Resources Ltd Victoria River joint venture project comprises 6 tenements, mostly in the Victoria River region of the northern part of the Northern Territory. NuPower entered into this joint venture with Jupiter Mines Limited on 19th August 2008. This annual report is concerned with the Barry Creek tenement (EL 25850). No prior exploration was conducted by Jupiter Mines. A reconnaissance visit was conducted and involved identification of access routes and investigation of radiometric anomalies within the tenement. This involved geological mapping and ground checking of the anomalies using a hand held scintillometer. Outcrop is generally subdued with radiometric anomalies thought to represent minor surface enrichment of uranium associated with the widespread development of ferruginous and lateritic weathering profiles developed over the strongly weathered Antrim Plateau Volcanics. Exploration by NuPower Resources in year 1- A reconnaissance visit was conducted to identify access routes and investigate the nature of the radiometric anomalies within the tenement. This involved geological mapping, ground checking of the anomalies using a hand held scintillometer and sampling of selected outcrops. Note that they are confined to the higher ground and are generally flat-lying. Escarpments and steep changes in slope, associated with gully incision, occur on their margins where the lateritic palaeosurface has been eroded by modern drainage. It is clear that the radiometric anomalies are associated with mapped occurrences of ferruginous and lateritic units (Czl) whilst occurrences of Cenozoic soils (Czb and Czs) and modern alluvium (Qa) exhibit a lower radiometric response. These anomalies are most pronounced on the margins of the escarpments (due to mass effects and the sharp change in relief) and extend downslope in the form of a broad apron of lateritic scree flanking the escarpments. Downslope, the anomalies are highlighted by the contrast between the weakly radioactive lateritic material and the nonradioactive soils and alluvium within the modern drainage courses.
