Annual report for EL 25340 Illogwa Creek to 7 February 2008

Abstract

EL 25340 was acquired to investigate airborne radiometric uranium anomalies within the Palaeoproterozoic eastern Arunta Province. The work carried out on EL 25340 during the first 12 months included a review of geophysical data and a helicopter-assisted reconnaissance sampling program over airborne radiometric anomalies. Further work is warranted on the EL to follow-up radiometric anomalies under cover. The main zone of high radiometrics was traversed with an Exploranium GR135 spectrometer and 8 rock chip samples were taken for multi-element analysis at ALS Chemex laboratories in Alice Springs. The maximum uranium value assayed was 5.4 ppm in a sheared quartz-feldpspar-tourmaline vein. Traversing across the anomaly revealed thin colluvium and alluvium with abundant augen gneiss and amphibolite boulders and tourmaline lag in a matrix of red-brown soil. Protruding through the colluvium were sporadic outcrops of sheared coarse-grained granitic augen gneiss containing porphyroblasts of tourmaline, minor pegmatite and amphibolite.
