Red Hill Minerals Begins 1,200m Diamond Drilling at Expanded Anabama Project

Red Hill Minerals has kicked off a 1,200 metre diamond drilling campaign targeting a strong off-hole conductor at its recently expanded Anabama copper-gold project in South Australia, aiming to extend known mineralisation along a now 25-kilometre shear zone.

  • Diamond drilling targets off-hole conductor from DHEM survey
  • Project strike length extended to over 25 kilometres with Cronje Dam addition
  • Previous drilling confirmed high-grade copper-gold-silver mineralisation at depth
  • Two holes planned to test along strike of geophysical anomalies
  • Drilling expected to complete by late August with follow-up DHEM surveys

Diamond Drilling Targets Hidden Mineralisation at Anabama

Red Hill Minerals Limited (ASX:RHI) has commenced a 1,200 metre diamond drilling program at its Anabama copper-gold project in South Australia, part of the Curnamona Earn-In Joint Venture with Spectre Metals. The program aims to test along strike of a strong off-hole conductor identified by downhole electromagnetic (DHEM) surveying of drillhole 25ANDD001, which previously intercepted high-grade copper-gold-silver mineralisation hosted in quartz-carbonate veins.

The first hole is designed to extend 150 metres southwest of the conductor plates detected in 25ANDD001, drilling to 700 metres, while the second hole will test a further 450 metres along strike to the southwest, targeting an anomaly defined by a 20.4 line kilometre induced polarisation (IP) survey. Drilling is expected to finish by late August, with both holes to be cased for subsequent DHEM surveys to refine conductor locations near the collars.

Expanding the Anabama-Redan Shear Zone

The Anabama Project has been expanded with the addition of the adjacent Cronje Dam tenement, granted through South Australia’s Exploration Release Area process. This acquisition increases the prospective strike length of the Anabama-Redan Shear Zone to over 25 kilometres, extending the known structural corridor that hosts copper-gold mineralisation.

Historical drilling focused mostly on near-surface mineralisation over a two-kilometre section, but recent diamond drilling in December 2025 confirmed the continuation of mineralisation at depth, some 130 metres below previous drillholes. Notable assays from 25ANDD001 include 20 metres at 0.6% copper, 0.2 g/t gold, and 3.0 g/t silver starting from 313.1 metres, with higher-grade intercepts within this interval.

Geophysical Surveys Highlight New Targets

The DHEM survey over 25ANDD001 recorded two conductive plates aligned along strike with modelled copper mineralisation, providing compelling targets for the current drill program. The IP survey also identified a significant anomaly along strike, which the second planned hole will test.

Executive Chairman Joshua Pitt highlighted the importance of these geophysical results, stating that the off-hole conductor shares a similar dip to known mineralisation and represents an exciting target for undiscovered mineralisation beneath the historic drill area.

Next Steps in Exploration

Following completion of drilling, Red Hill plans to conduct DHEM surveys on both holes to detect any conductors near the drill collars that might indicate additional mineralisation. The proximity of the new drillhole 26ANDD001 to the prior 25ANDD001 will help build high-confidence models of the conductor system over a significant strike length.

The Cronje Dam tenement, now part of the JV, has seen limited deeper drilling despite historic anomalous copper results from shallow RAB drilling. This makes it a compelling target for further exploration, with ongoing work to digitise and analyse historic data underway.

Bottom Line?

The current drilling and geophysical program at Anabama could significantly expand the known copper-gold system along a 25-kilometre shear zone, but results and assays over coming months will be critical to assess the project’s resource potential.

Questions in the middle?

  • Will the new drillholes confirm extensions of high-grade mineralisation along strike?
  • How will the DHEM survey results influence targeting for future drilling campaigns?
  • Could the Cronje Dam tenement reveal a new zone of mineralisation within the extended shear zone?
