National scale critical and strategic mineral potential assessments to support decision making in the net zero transition

With the projected increase in demand for critical minerals and strategic materials required to meet net zero objectives by 2050, a series of national-scale mineral potential assessments are being delivered as part of the Resourcing Australia's Prosperity initiative at Geoscience Australia. In addition to providing an evidence-base for supporting government decision-making, these precompetitive assessments aim to support the discovery of deposits that host critical minerals and strategic materials by reducing the exploration search space and promoting increased exploration investment. The mineral potential assessments integrate both new and legacy geoscience data and aim to delineate prospective belts or districts where favourable geological, geophysical, and geochemical criteria that represent evidence of relevant mineral systems processes are present. To date, assessments for nickel-copper-platinum group element, sediment-hosted base metal, carbonatite-related rare earth element, and iron oxide-copper-gold mineral systems have been undertaken at a national-scale by Geoscience Australia as part of previous programs, with additional mineral systems currently being assessed. The methodology used in each assessment is reviewed on a case-by-case basis due to the widely varying availability of known deposits and occurrences that can be used to train data-driven models using statistics or machine learning for each mineral system. Using a mineral systems-based approach as a basis, the Resourcing Australia's Prosperity initiative aims to deliver a series of commodity potential maps for all of Australia’s critical minerals and strategic materials. An example of how this may be achieved for copper will be presented, with an interim map highlighting Australia’s copper potential based on the mineral systems modelled to date.

Report on organic petrology and maturation in a suite of samples from the Birrindudu basin, Northern Territory

This study was commissioned by Geoscience Australia (GA) as part of the Resourcing Australia's Prosperity initiative to produce a report on the organic petrology of rock samples from drill holes in the Birrindudu Basin, Northern Territory, Australia. A suite of 97 drill core samples from 5 drill holes was analysed using standard organic petrological methods to identify the types of organic matter present, assess their relative abundances and determine the levels of thermal maturity attained by the sedimentary organic matter using the reflectance of organoclasts present. The primary organic matter identified was non-fluorescing coalified alginite, likely from filamentous cyanobacteria, along with significant graphite in 10 samples from the undifferentiated basement. The graphite likely formed through contact metamorphism and tectonic shearing. Secondary organic matter included bitumen, diffused unstructured organic matter, and dead oil droplets.

Empowering Exploration with National Scale Maps

Geoscience Australia (GA) is committed to enabling a strong resources sector through its landmark Resourcing Australia's Prosperity initiative. A focus for this initiative is integrated and standardised geoscientific mapping to improve understanding of what lies on and beneath the land surface. National-scale surface and subsurface geological maps and derivative thematic maps that highlight geology of interest provide the framework needed to map Australia’s onshore resource potential, including for critical minerals and strategic materials, thereby reducing exploration risk and accelerating new discoveries. Digital flagship products such as the national-scale Layered Geology of Australia and Alkaline Rocks Atlas of Australia are compiled from published datasets at a variety of scales and with geological information harmonised across state and territory borders. The 1:1 million scale Layered Geology dataset extrapolates Australia’s surface geology beneath cover to produce seamless geology for five time slices. Geological units captured in these layers are attributed with rich information sourced from the Australian Stratigraphic Units Database. Augmenting these layers with depth points using GA’s Estimates of Geological and Geophysical Surfaces database will add that critical third dimension and fundamentally change the exploration landscape, opening up that depth component and broadening the resource search space. Higher resolution products such as the Alkaline Rocks Atlas capture smaller scale units of interest, like alkaline igneous rocks, which are volumetrically minor but a significant source of critical minerals such as rare earth elements. Thematic maps like this can provide vectors to regions of potential mineralisation and are important inputs for national resource prospectivity assessments.

West Musgrave 3D palaeovalley point dataset ~ Base of Cenozoic depth estimates made using AusAEM (airborne electromagnetic) conductivity models

As part of the Exploring for the Future program, Geoscience Australia undertook an investigation into palaeovalley groundwater resources within the West Musgrave region of Australia (Symington et al., 2024). The investigation, which spans the WA, SA and NT borders, inferred the architecture of the region’s palaeovalleys via interpretation of airborne electromagnetic conductivity models, borehole data and geologic outcrop. This record presents the base of Cenozoic depth estimates made along the AusAEM airborne electromagnetic (AEM) conductivity models used in this investigation.

To maximize the value of depth estimates from projects across Geoscience Australia, the Estimates of Geological and Geophysical Surfaces (EGGS) database was developed to store standardised interpretations of stratigraphic horizons (Mathews et al., 2020).

Standardisation in part aims to maintain the ability for users to take point data/depth estimates from the EGGS database and recombine them back into their original line data/interpreted horizons. To achieve this, all points along any particular segment need to maintain identical metadata. This requirement means that annotations made to a single point will propagate across the whole segment of which it is part.

As such, the base of Cenozoic depth estimates from this investigation, originally created with Petrel, were annotated to enhance the value of the data and then standardised to comply with the requirements of the database. These modifications facilitate the integration of these depth estimates into future models delivered under the Resourcing Australia's Prosperity initiative (RAPi).

A Stratigraphic Reconstruction of Bulk Volatile Chemistry from Fluid Inclusions in MSFDD001, Birrindudu Basin, Australia

This report presents the results from a fluid inclusion stratigraphy (FIS) study on the drill hole MSFDD001 (Longitude 130.4428; Latitude -17.0478) located in the central Birrindudu Basin, Northern Territory. FIS analysis, where volatile components trapped with fluid inclusions are released and analysed revealing the level of exposure of the drill hole section to migrating fluids, was performed on 162 core samples from 89-502 m. 

These data form part of a drill core analytical program undertaken as part of the Birrindudu Deep Dive project. This project is delivered under the Resourcing Australia's Prosperity initiative, the Australian Government’s 35-year precompetitive geoscience initiative, led by Geoscience Australia, to accelerate the discovery of critical minerals and other resources, to support Australia’s net zero transition and enable responsible management of all resources.

Continental-scale interpretation of airborne electromagnetics. Supporting regional groundwater systems understanding and management.

In Australia, widespread sedimentary basin and regolith cover host groundwater resources while obscuring underlying hydrostratigraphic units of interest, presenting challenges for hydrogeologists, environmental managers, communities, and decision makers. As an attempt to address these challenges, we interpret conductivity-depth models derived from Geoscience Australia’s 20 km line-spaced AusAEM airborne electromagnetic (AEM) data and other AEM state and industry-flown surveys.

Integration of AEM conductivity sections with supporting information such as boreholes, geophysics, surface and subsurface geology maps, and stratigraphic unit information facilitates the production of chronostratigraphic AEM interpretations. These interpretations help characterise the near-surface geology to depths of up to ~300&nbsp;m.

Homogenous layered chronostratigraphic interpretation of AEM conductivity sections currently covers over 115,000 line-km, providing consistently formatted line segments (~30,000) or depth estimate points (600,000) across approximately 27% of the Australian continent, or 46% of the 20km line-spaced data. Furthermore, rich stratigraphic, confidence and other interpretation-specific metadata are attributed to these interpretations.

These interpretations provide a multidisciplinary tool for a range of uses. In a groundwater context, they offer valuable information about palaeovalley presence, morphology, hydrostratigraphic unit distribution, structure and depth, and can also support interpretations of groundwater flow direction, salinity and availability.

The data are available in multiple formats compatible with a wide range of software packages, providing extensive data to academia, government and industry. Applications include regional hydrogeological studies, water resource identification, extraction and management, management of groundwater dependent ecosystems, and mapping seawater intrusion.

Combining old and new, a 35 year vision to map Australia's groundwater under the Resourcing Australia's Prosperity Initiative

Resourcing Australia's Prosperity is a 35-year initiative, led by Geoscience Australia, to enhance knowledge of Australia’s&nbsp;geology and groundwater systems.&nbsp;The groundwater project under the Initiative&nbsp;enhances understanding, management, and sustainable use of Australia’s groundwater by assessing groundwater systems, their connectivity and relationships with other natural resources across the continent. The groundwater project is taking national groundwater mapping to the next level and builds on foundational work under the recently completed Exploring for the Future Program.

The groundwater project comprises three key components. National 3D Groundwater Systems Mapping is enhancing National 3D geology models to incorporate hydrostratigraphy and build consistency in national groundwater databases through multi-agency collaboration. The National Hydrogeological Inventory provides a unified, multi-tier repository of hydrogeological data, ensuring consistency and accessibility for groundwater studies and management. The Groundwater Atlas&nbsp;integrates 3D models and hydrogeological data for priority regions, presented as a map compendium. The groundwater Atlas is designed to present groundwater conceptual models in a visually engaging manner for a broad audience.

By delivering these outcomes, the project strengthens Australia’s capacity to sustainably manage groundwater resources for current and future generations. It supports the clean energy transition by providing critical groundwater data, enhances national groundwater information access for government, industry, and communities, and improves data coverage and model confidence across state and territory jurisdictions. 

Ongoing engagement with the Australian and International groundwater community will be critical to design and deliver groundwater products that meet the needs of all Australians.

L216 Boodjamulla-Croydon Seismic Survey

The Geological Survey of Queensland (GSQ) and Geoscience Australia (GA) acquired 842 km of seismic data in northern Queensland between 24 July and 3 September 2025. The L216 Boodjamulla–Croydon seismic survey was designed to image crustal architecture from the Western Subprovince of the Mount Isa Inlier, across the Carpentaria Basin and into the Croydon Province of the Georgetown Inlier. The survey comprises three transects routed along existing roads to minimise new ground disturbance and streamline land access, with active engagement across the Burke, Carpentaria, Mount Isa City, Cloncurry and Croydon shires. Field operations were delivered by Terrex Seismic under joint GSQ–GA management and were co-funded through the Queensland Government and the Australian Government’s Resourcing Australia's Prosperity initiative (RAPi).

&nbsp;

In earlier deep-crustal surveys in Queensland and the Northern Territory, night-time acquisition was used to reduce noise and improve imaging of deeper structures. Building on this approach, the current survey introduced a complementary daytime program using the same receiver layout to improve resolution of upper-crustal and near-surface features. In addition, nodes recorded continuously, producing a passive seismic dataset suitable for ambient noise tomography and interferometric analyses. This is the first survey to combine all these approaches to generate three complementary datasets from a single program. Further details on the acquisition parameters and deployment logistics are provided in the accompanying acquisition report.

&nbsp;

This eCat record provides the central long-term access point for data products associated with the L216 Boodjamulla–Croydon seismic survey. Data will be released in stages as it becomes available.

&nbsp;

Raw field data for this survey are now available from Geoscience Australia. To request access, please email client services at ClientServices@ga.gov.au quoting eCat #150760.
