Wongamine Project

The Wongamine project (E70/ 4692) is located 14km northeast of Toodyay. Historically a gold project in the 1930s, however the source of anomalous gold readings was never found.

Target Commodities

  • Ni-Cu-PGE hosted in mafic / ultra-mafic intrusive rocks
  • Orogenic Gold

Project History

  • Extensive shallow drilling for bauxite;
  • Considerable exploration for Iron ore – including Cliffs Asia Pacific Iron Ore, Reedy Lagoon Corporation, Western Mining, and others.

Exploration Analysis

  • Large fold (2.5km) truncated by shear zone (8km);
  • High amplitude discordant magnetic anomalies may indicate mafic-ultramafic intrusive rocks;
  • Ultramafic rocks mapped at surface;
  • 5 moderate and 3 strong conductors identified in an Airborne Electromagnetic survey conducted by NRL (2022);
  • An Induce Polarisation survey by NRL showed a strong chargeability anomaly across both lines,
  • Sulphides identified in ultramafic rocks drilled in 2019 – not assayed.
