Annual report for EL 24867 Rum Jungle 15 March 2006 to 14 March 2007

Abstract

During 2006 Uranium West engaged geological consultants Ravensgate Pty Ltd to conduct a geological assessment of the economic potential of its tenure in the northern Territory, concentrating on Uranium potential. Ravensgate identified the main target style for uranium mineralisation within the tenure as Proterozoic unconformity-related, where deposits occur proximal to unconformities, generally between fractured, brecciated uranium enriched basement rocks and overlying porous sediments. Several occurrences of this type-mineralisation lie near to the project area (Dysons (U), Whites (U-Cu-Co), Intermediate (Cu-Co) and Browns (Pb-Cu-Co-Ni-Zn) deposits). Recommendations for exploration from Ravensgate included geological mapping in order to identify the unconformity between the Mt Partridge group and the Rum Jungle Complex, if it exists within EL 24867. A second study by Southern Geoscience Pty. Ltd. (Southern Geoscience) a geophysical consulting group was commissioned later in the year, with geophysics as a focus (Southern Geoscience 2006). Open-file government geological and geophysical data were compiled and assessed for geological setting, mineralization potential and quality of existing geophysical data. The primary aim of this assessment was to evaluate the uranium prospectivity of the area, identify potential targets and provide exploration recommendations. Evaluation of the polymetallic/base metal potential was a secondary objective. Government airborne magnetic and radiometric surveys across the tenement comprise 200 m line spaced data. Regional gravity stations are sparsely located along regional roads and traverses at 200-500 m station spacings. Landsat and SRTM digital elevation data are also available. The extent of outcropping bedrock and residual cover is sufficient for the airborne radiometrics to be representative of the bedrock from a mapping point of view. No specific targets were delineated during the study. The southwestern half of EL 24867 is considered moderately to strongly prospective for unconformity-related and epigenetic uranium and stratabound-stratiform polymetallic/base metal mineralization. Recommendations from this study were that these areas should be flown with high-resolution airborne magnetics and radiometrics.
