First annual report on Dunmarra Basin Project

Abstract

The Dunmarra Basin Uranium Project is located approximately 22 kilometres east of Three Ways Motor Inn situated corner of the Stuart and the Carpentaria Highways in the Northern Territory. This report describes the results of literature research and target generation based on re-interpretation of radiometric data and surface rock chip/soil sampling program carried out during the first year of the Licence. The Dunmarra Basin contains many minor copper mineral occurrences. The whole basin in comparisons to other geological provinces in the Northern Territory remains under explored. First and second order radiometric anomalies present within the Project areas still remain not investigated. The radiometric anomalies are associated with the favourable lithologies which have the potential to hosted uranium deposits are found in the Northern Territory, namely the Lower Cretaceous (lateritised claystone, soft grey claystone, impure sandstone, white quartz sandstone, conglomerates). In terms of both regional and project scale structure the Project areas are ideally situated for sandstone and unconformity style and sedimentary uranium roll front type uranium deposits. In August 2008, Arnhem Exploration Services was commissioned to carry out a reconnaissance program on EL 25838. Work carried out included soil sampling (200g, 10-20 cm, -80#), scintillometer readings and collecting rock samples along specified traverses. A total of 8 soil samples and two rock samples were collected. Soil samples are numbered from 10001 to 10008, the one rock samples are numbered 10010R. Assay results outlined several low order uranium anomalies have been delineated within central portion of EL 25838. The remaining traverses in the program were inaccessible: the track shown on the topographic map leading through the main part of the anomaly has not been maintained for many years and is impassable to four wheel drives. It may be possible to gain access on quad bikes from the east or south boundary fences.
