Recharge Metals Eyes Higher-Grade Copper Potential At Brandy Hill South

Recharge Metals Ltd (ASX:REC) has proposed a new model for copper mineralisation from its recent technical review at the Brandy Hill South Project, situated in the Murchison region of Western Australia.

As part of the technical review, highly regarded geologist Dr Steve Beresford assessed the project’s development potential.

Encouragingly, Dr Beresford highlighted the potential for higher grade porphyry style copper mineralisation at Brandy Hill South.

Technical Review Summary

The technical review incorporated visual logging, pXRF data, laboratory assay results from Recharge’s previous drilling programs and Tornado micro XRF imagery of the drill core.

Notably, the key data supporting the proposed porphyry model included geochemical data as well as geological relationships observed in the drill core and the Tornado imagery.

Consequently, the exploration data supports evidence of a porphyry copper system, which is well preserved compared to similar deposits in WA.

“We are encouraged by Steve’s observations and findings, which has provided a relatively simple low-cost work program to advance the project,” said MD Felicity Repacholi

Previous drilling

Previous drilling at Brandy Hill South intersected:

  • 33m @ 0.97% Cu from 59m;
  • 77m @ 0.33% Cu from 209m;
  • 52m @ 0.45% Cu from 54m incl. 1m @ 1.11% Cu, 1m @ 1.81% Cu & 1m @ 1.72% Cu; and
  • 5m @ 1.02% Cu from 375.5m incl. 7.5m @ 1.65% Cu.

Importantly, the copper mineralisation is defined over a strike length of 500 metres.

The mineralisation remains open along strike and at depth.

What’s next

Dr Beresford’s review highlighted several key features in historical data as well as the next steps to advance Brandy Hill South.

Looking ahead, the proposed next steps at the project include:

  • Trial the use of induced polarisation (IP) to detect disseminated sulphides associated with copper mineralisation;
  • A detailed paragenetic study (including re-logging of existing drillcore) of a cross-section including BHRCD018 to ascertain the number of porphyries and vein paragenesis;
  • Short Wave IR (SWIR) scanning of a single hole or the use of a portable infra-red mineral analyser (PIMA) / ASD mineral spectrometer) to quantify alteration styles and expand the lithogeochemical interpretation.
