Increased mineral prospectivity in the southeast of NSW

Abstract

Understanding the relationship between mineralisation and magnetic intrusive complexes is pivotal in an exploration program. With the recent release of high resolution airborne geophysical data over the southeast of New South Wales, it is timely to complete a detailed study of the magnetic data that will assist the geological mapping and further understanding of the structure of the area. Preliminary studies in determining the depth to magnetic source have been completed, including analysis of both manual and semi-automatic methods. Results are consistent and viable, and show general agreement between various modelling applications. A more detailed and exhaustive study is underway that will include comparisons using both line and grid data, and with various commercial semi-automatic magnetic modelling packages.
