Abstract
<div>Geoscience Australia’s Exploring for the Future (EFTF) program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to a low emissions economy, strong resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.</div><div><br></div><div>As part of the program, Geoscience Australia (GA) provides a range of established techniques to capture precompetitive geoscience data across underexplored regions to stimulate industry investment in frontier regions of Australia. The Paleo to Mesoproterozoic Birrindudu Basin is an underexplored frontier basin located in northwestern Northern Territory and northeastern Western Australia. The Birrindudu Basin is a region of focus for the second phase of the EFTF program (2020–2024) as it contains strata of similar age to the prospective McArthur Basin, South Nicholson region and Mount Isa Province, but remains comparatively poorly understood. Furthermore, much of the age of the stratigraphy of the Birrindudu Basin, particularly the younger stratigraphic units, and regional correlations to the greater McArthur Basin remains provisional and speculative. Interpretation of industry seismic data indicates that Proterozoic strata in the western Beetaloo Sub-basin and eastern Birrindudu Basin are continuous in sub-surface. </div><div><br></div><div>In order to provide an improved understanding of the stratigraphy, basin architecture and resource potential of the Birrindudu Basin and surrounding region, GA, in collaboration with the Northern Territory Geological Survey, is acquiring geophysical, geochronological, isotopic, geochemical and geomechanical data as part of phase two of EFTF. The data and results will be released, as they are available, through GA’s eCat Product Catalogue.</div><div><br></div><div>This report presents SHRIMP U-Pb zircon geochronology results on a single igneous sample taken from exploration drillhole LBD2, located in the Birrindudu Basin, intersecting both Paleoproterozoic Limbunya Group and underlying low-grade basement metamorphic rocks.</div>

Lineage
<div>A sample of altered porphyry from the exploration drillhole LBD2 (Limbunya region of northwestern Northern Territory) was analysed by SHRIMP (U-Pb zircon) to assess the age of igneous intrusion and better constrain the age of sedimentation in the region. This work forms part of the EFTF program under the Officer-Musgrave-Birrindudu module.</div>
