<div>The Northwest Northern Territory Seismic Survey (NW NT Seismic Survey) was acquired as part of the Australian Government's Exploring for the Future (EFTF) program, conducted from 5 August to 20 September 2023. This ambitious project is a collaboration between Geoscience Australia and the Northern Territory Geological Survey, aimed to systematically map the subsurface geology of a significant yet largely unexplored region of Australia. Covering an extensive area that includes the Birrindudu Basin, Kalkarindji Suite, Tanami, and Wolfe Basin, the survey successfully acquired about 846 kilometers of high-resolution seismic data across four seismic transects, specifically designated as 23GA-NT1 (54.5 km and 184.5 km in two separate sections), 23GA-NT2 (112 km), 23GA-NT3 (221.46 km), and 23GA-NT4 (274.2 km).</div><div><br></div><div>This seismic campaign is part of a strategic effort to illuminate the geological framework and evaluate the resource potential within these regions, which are considered highly prospective for minerals, geoenergy, geological storage and groundwater resources. By deploying advanced seismic acquisition technologies to capture detailed images of the Earth's crust, this survey provides foundational data for identifying the region's geological features and resource potential, such as basin geometry and fault systems. The data derived from this survey are expected to play a pivotal role in guiding future exploration activities, attracting investment to the region, and ultimately contributing to the sustainable development of Australia's natural resources.</div><div><br></div><div>The project underscores the commitment of the Australian Government and its partners to enhance the geoscientific understanding of the continent's frontier regions. The findings from the NW NT Seismic Survey will advance our knowledge of Australia's geology and unlock new opportunities for exploration and economic development in the northwest Northern Territory. Through the dissemination of precompetitive geoscience data, the EFTF program continues to foster innovation and collaboration across the exploration sector, ensuring that Australia remains at the forefront of global efforts to secure a sustainable and prosperous future.</div><div><br></div> <b>To access the survey data and related products, please contact clientservices@ga.gov.au and quote eCat#149287.

<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.
