A Large-Scale Copper-Gold and Emerging REE Exploration Opportunity in Western Australia

The Ashburton Project provides Austin Metals Limited (ASX: AYT) with exposure to a substantial copper-gold, base metals and emerging rare earth element (REE) exploration opportunity within the prospective and comparatively underexplored Ashburton Basin of Western Australia.
Located on Ashburton Downs Station, approximately 75km southwest of Paraburdoo, the project encompasses a significant landholding of approximately 527km² across multiple granted exploration licences and a prospecting licence.

Compelling Geological Setting

The project is underlain by Proterozoic sedimentary rocks disrupted by regionally significant faults and folds. This structural architecture provides favourable pathways and potential traps for hydrothermal fluids and supports Austin’s strategy of targeting copper-gold and broader base metal mineralisation.
Previous reconnaissance exploration has also identified hydrothermal breccias within the project area, providing an additional exploration opportunity and potential for epithermal-style mineralisation.

Emerging Rare Earth Element Potential

Importantly, the Ashburton region is also emerging as an area of interest for rare earth element exploration. Regional work has identified REE enrichment within sedimentary units associated with major structures, including the Blair Fault corridor, while high-grade surface REE occurrences have been reported elsewhere within the broader basin.

Austin’s extensive tenure is positioned within this prospective regional geological setting and contains significant areas of Ashburton Basin stratigraphy, regional-scale faults and structural intersections. These geological features may provide favourable pathways and traps for REE-bearing fluids and offer the Company an additional exploration opportunity alongside its existing copper-gold and base metals targets.

The combination of prospective stratigraphy, structural complexity and regional REE anomalism provides a compelling basis for targeted geochemical, radiometric and geological investigation to assess the REE potential across Austin’s tenure.

Building a Pipeline of Exploration Targets

Austin’s strategy at Ashburton is to systematically develop and refine exploration targets through the integration of geological, structural, geochemical and geophysical datasets across its extensive landholding.

Future exploration can incorporate detailed geological mapping, structural interpretation, multi-element geochemical sampling and targeted radiometric assessment. This work will assist in evaluating both the project’s established copper-gold and base metals potential and its emerging REE opportunity, with the objective of identifying priority areas for follow-up field programmes and potential future drill testing.

Strategic Portfolio Diversification

While Austin’s near-term exploration activities have been focused on advancing its flagship Austin Gold Project, Ashburton provides the Company with a substantial second exploration platform and exposure to a broader range of commodities.

With approximately 527km² of prospective tenure, favourable regional structures, multiple potential styles of mineralisation and emerging REE prospectivity, the Ashburton Project represents an important strategic component of Austin Metals’ Western Australian exploration portfolio and offers considerable scope for systematic target generation and future discovery.
