Airborne geophysical survey, Flora River, Northern Territory

Abstract

In September 2012 the Flora River NT Airborne Geophysical Survey was flown over EL 26899 which is held by Century Hill Pty Ltd., a subsidiary company of Consolidated Global Investment Limited (CGI). It is an airborne magnetic-radiometric survey which was flown at 200m line spacing. This survey was conducted in collaboration with the Northern Territory Government. The objective of the survey was to upgrade magnetic-radiometric coverage over the tenement from a current coverage of 1500m line spacing. The survey was flown between 11 September and 14 September 2012 and it included 1,835 line km. The work was proposed by CGI to extend the quality of data coverage further into this greenfields area to enable assessment and further exploration to proceed on the basis of necessary data density. The survey has provided high quality data which has enabled detailed identification of geological structure. Radiometric data has been interpreted and elevated values of U/Th have been identified. These anomalies are proposed to be indicators of potential Heavy Rare Earth Elements (HREE) mineralisation based on similar anomalies documented to the north.
