Abstract: 

An Ambient Noise Tomography (ANT) survey was conducted in the Duck Creek Project area, north of Nyngan in the northern part of the Macquarie Arc to explore for porphyry-related copper-gold mineralisation. The area has approximately 400m of post-mineral cover. Regional aeromagnetic and drill data has highlighted zones of porphyry-style alteration. The goal of the ANT survey was to provide a 3D image of the basement rocks down to at least 1.5 km depth and identify deep intrusions and alteration zones associated with porphyry-style mineralization. The ANT survey identified an unknown northeast trending low velocity zone that contains several areas of interest for further analysis and follow-up. This includes at least two, kilometer scale high velocity bodies at 1.2 km depth that could represent intrusions, and an intriguing “donut” feature.

Author Biography: Darren graduated from the University of the Witwatersrand in Johannesburg, South Africa with a Geophysics (Hons) degree. Initially he worked in deep Gold mines analysing mining induced seismicity, to ensure safe underground mining conditions. He then moved to Platinum exploration in the Bushveld Igneous Complex planning drillholes, logging core and managing exploration data. A large part of his career was spent in airborne geophysics with Fugro / CGG / Xcalibur where he has held various roles focusing on geophysical data processing & interpretation as well as business development. At Fleet Space Technologies he entered the emerging field of ambient noise tomography and applies it to solve mineral exploration problems.
