Annual report year ending 12 May 1998 EL 5891

Abstract

Work conducted during the year included ongoing geological and regolith mapping, follow up of airborne anomalism, geochemical sampling included stream sediment, rock chip, ferricrete, auger and RAB hole. Radiometric sandstone anomalies were followed up within the Kombolgie mudstone and are located in a linear NNW trending zone extending for 6Km and include the Marligur Pass, Arg 11, 12 anomalies. They are characterised by haematite alteration, bleaching, heavy mineral banding and some quartz veining. RAB and diamond drilling show that the Kombolgie Sandstone overlies basement gneiss of the Nimbuwah Complex, with radiometric anomalism being associated with Aurari Fault. Basement anomalies were located at ANG 1 and Angarlban prospects and are characterised by potassium alteration with some minor U anomalism. In addition at prospect ANG 3 a number of 'spot' radiometric anomalism is associated with rubbly ferricrete but RAB drilling did not indicate radiometric anomalism below the surficial sediments.
