Partial relinquishment report for EL 25881 for the period 12 October 2008 to 11 October 2009

Abstract

This report details exploration undertaken over the area of 50% 3rd year compulsory drop off for EL 25881 for the period from 12th October 2007 and 11th October 2009. Exploration carried out on the drop off area EL 25881 included compilation of geophysical data sets. A review of remotely sourced geophysical data sets identified areas within EL 25881 with elevated responses for Uranium, Thorium and Potassium. The anomalous responses located within EL 25881are interpreted to correspond directly to a window within the Laingang Formation and directly onto the Goobaieri Formation. The window of Goobaieri Formations may be close to the basement. The presence of Whitewater Volcanic units which are Lower Proterozoic ages may be a source of uranium or alternatively a host for remobilised uranium mineralisation. No areas of anomalous values for U, Th and K fall within the areas for the 50% drop off.
