<div><strong>Output Type: </strong>Exploring for the Future Extended Abstract</div><div><br></div><div><strong>Short Abstract: </strong>As part of the Exploring for the Future (EFTF) program, Geoscience Australia acquired new 2D seismic reflection data across the northwestern Northern Territory (NT). Identified as an area of little knowledge during the Birrindudu Basin Inventory activity the Northwest Northern Territory Seismic Survey was acquired between August and September 2023 by Geoscience Australia and co-funded by the Northern Territory Government. The survey crosses the Proterozoic rocks of the Birrindudu Basin that are thought to be age equivalent to those within the McArthur Basin and Mount Isa Province to the east, which contain some of the world’s largest sediment-hosted base metals deposits, including McArthur River and Century and Mt Isa Pb-Zn-Cu mines. Further, additional complimentary studies provide evidence for an effective petroleum system in the Birrindudu Basin, demonstrated by the occurrence of live oil bleeds in the drill hole 99VRNTGSDD1 and good source rocks were identified mostly in the Paleoproterozoic Limbunya Group. However, many data gaps exist and much of the prospectivity for hydrocarbons in the Birrindudu Basin is inferred from the presence of equivalent-aged rocks in the highly prospective Paleo- to Mesoproterozoic McArthur Basin. To address data gaps, this new regional 2D seismic data was acquired and combined with a comprehensive sampling and analytical program on newly collected drill core samples, to assess the basin’s resource potential. The Northwest Northern Territory Seismic Survey has increased the seismic coverage of the Birrindudu Basin by ~900 km, and links to surveys in both the Beetaloo Sub-basin and Tanami. Interpretation of these deep seismic lines in combination with newly acquired data from drill cores and legacy 2D seismic lines will substantially improve the knowledge of mineral and energy systems in the northwestern Northern Territory.</div><div><br></div><div><strong>Citation: </strong>Henson, P., Anderson, J.R., Southby, C., Carson, C., Costelloe, R.D., Jorgensen, D., Grosjean, E. & Carr, L.K., 2024.
