Red Hill Extends Anabama Copper-Gold Strike to Over 6km with New IP Survey

Expanding the Anabama Copper-Gold Prospect

Red Hill Minerals Limited (ASX – RHI) has announced a significant advancement in its exploration efforts at the Anabama copper-gold target in South Australia. The company recently completed an additional six induced polarisation (IP) survey lines, bringing the total survey line length to 20.4 kilometres. This latest geophysical work has extended the strike length of chargeability anomalism along the prospective Anabama-Redan Shear Zone to over six kilometres, nearly tripling the previously defined target area.

Geophysical Insights and Historic Correlations

The IP survey results reveal extensive chargeability and resistivity anomalies that strongly correlate with historic copper and gold mineralisation identified in previous drilling campaigns. Notably, the areas exhibiting the highest chargeability remain untested by drilling, highlighting new zones of potential mineralisation. The survey lines were strategically oriented perpendicular to the shear zone to provide unbiased sampling of the geological structures controlling mineralisation.

Strategic Location and Joint Venture Framework

The Anabama Project covers 840 square kilometres within the Olary Province, approximately 140 kilometres southwest of Broken Hill, New South Wales. It forms part of Red Hill’s Curnamona Earn-In Joint Venture with Peel Mining Limited (ASX – PEX). The region is known for its copper, gold, and uranium prospects, with historic workings concentrated around the Anabama and White Rocks targets. Despite previous exploration dating back to the late 2000s, the recent geophysical data suggest that significant mineralisation remains to be delineated along the shear zone.

Upcoming Drilling Campaign

Building on these encouraging geophysical results, Red Hill is progressing heritage surveys and drill planning with the aim of commencing a substantial drilling program by the end of 2025. The planned campaign includes up to 6,000 metres of reverse circulation (RC) drilling and 2,000 metres of diamond drilling. This first-pass drill testing will target the newly identified IP anomalies to validate the geophysical indications and potentially expand the known mineralised footprint.

Balancing Optimism with Caution

While the IP survey provides a well-constrained target along the Anabama-Redan Shear Zone, it is important to note that chargeability anomalies can sometimes be caused by non-mineralised sulphides such as pyrite. Therefore, drill results will be critical to confirm the presence and extent of economically viable copper-gold mineralisation. The company’s methodical approach, including quality assurance measures and alignment with historical data, lends credibility to the prospectivity of the target.
