Auroch Minerals Limited (ASX:AOU) (Auroch or the Company) is pleased to advise that the ground IP survey has been completed over the Nepean North Prospect of the Nepean Project (Nepean) in Western Australia (Auroch Minerals 80%).


  • Ground Induced Polarisation (IP) survey over the Nepean North Prospect has been completed, with consistent strong bedrock chargeability anomalies identified that represent priority targets for follow-up drilling
  • 3,000m Reverse-circulation (RC) drill programme planned to test the peak response of the modelled IP targets in prospective, largely untested, geological positions for both gold and nickel sulphide mineralisation
  • RC programme includes seven drill-holes to test three shallow gold targets in the south of the Nepean Project, where previous drilling has intersected mineralisation ranging between 3 – 14 g/t Au1
  • Metallurgical test work is well advanced on the shallow high-grade nickel sulphide mineralisation identified near the historic Nepean nickel mine, with two of the three bulk samples tested to-date successfully producing a saleable nickel concentrate grade
  • Results are pending for pegmatite samples re-assayed for lithium-caesium-tantalum (LCT) mineralisation from two RC drill-holes along strike from a rock-chip sample that assayed 2.26% Li2O2
  • Diamond drilling at the Ragless Range Zinc Prospect of the Arden Project in South Australia has been completed, with down-hole radial IP surveys now underway
The ground Dipole-Dipole Induced Polarisation (DDIP) survey successfully identified strong chargeability anomalies (>37mV) located below the weathering profile on 16 of the 19 survey lines (Figure 1). Inversion models of the surveyed lines show the strong chargeability features are associated with both intrusive and extrusive mafics (orogenic gold targets) and on the contacts of the prospective ultramafic units (nickel sulphide targets). The IP chargeability anomalies represent priority targets for follow-updrill-testing.
