Drilling Reveals 4.2 g/t Gold Over 4m and 0.3% Copper at Austin Metals’ Sites

Exploration Breakthrough at Austin Project

Austin Metals Limited has announced significant progress in its Western Australian exploration efforts, with drilling results from the Austin and Ashburton Projects underscoring the potential for substantial mineral resources. At the Austin Project’s Mt Sandy Prospect, the company confirmed high-grade gold mineralisation hosted within a west-dipping shear zone extending over 500 metres along strike and remaining open in all directions. Notable intercepts include 4.0 metres at 4.2 grams per tonne gold, highlighted by a 1.0 metre section grading 12.6 grams per tonne.

These results are bolstered by a strong bismuth-gold correlation identified through laboratory analysis, which Austin Metals is leveraging as a pathfinder to refine ongoing exploration targeting. This geochemical relationship is a promising indicator of structurally controlled gold mineralisation typical of the region.

New Structural Insights at Brunswick Hill

At the nearby Brunswick Hill Prospect, drilling revealed a previously unrecognised northeast–southwest trending fault zone west of the main mineralised horizon. This discovery marks the first confirmed mineralisation outside the primary west-dipping lens, suggesting the presence of multiple mineralised structures within the Brunswick Hill system. Intercepts here include 1.0 metre at 3.0 grams per tonne gold, indicating additional zones worthy of follow-up.

Copper-Gold Potential at Ashburton’s Donnelly’s Prospect

The Ashburton Project, situated in the Pilbara region, revealed a laterally extensive copper-gold system at Donnelly’s Prospect, defined over 900 metres along strike and open in all directions. Drilling intercepted multiple mineralised zones with epithermal characteristics, including a 10-metre interval grading 0.6 grams per tonne gold and 0.3% copper. The mineralisation is associated with intense alteration zones and hydrothermal breccias, suggesting a magmatic-hydrothermal fluid source that could support significant copper-gold deposits.

These findings are particularly encouraging given the project's geological setting within the Ashburton Basin, known for orogenic gold and potential SEDEX and epithermal-style mineralisation.

Next Steps and Exploration Outlook

Austin Metals plans to expand the high-grade gold zones at Mt Sandy and test the newly identified fault structures at Brunswick Hill with further drilling. A targeted auger regolith sampling program is also planned to delineate mineralisation extensions and assess gold-bismuth anomalies along strike. Ground geophysical surveys will support targeting thicker zones of structurally controlled mineralisation.

At Ashburton, the company will continue target generation work, including commissioning expert assessment of the epithermal potential of hydrothermal breccias. These strategic steps aim to build on the current momentum and refine the understanding of mineralisation controls across both projects.
