COPPER SPRINGS PROJECT (Cu): STRATEGIC HIGHLIGHTS
  • 23 recorded non-continuous malachite, azurite (copper carbonates) and goethite (iron) gossanous occurrences over an 8km strike length.
  • Previous rock chips (external to copper occurrences) peak of 4% Cu & 3.4% Cu.
  • No previous drilling or modern geophysics testing of copper occurrences.
  • Targeting intrusion and shear related Cu-Ag-Au mineralisation.
  • Easy access with key infrastructure.

 

The Copper Springs Project is on Exploration Licence Application E80/6036 located 100km northeast of Halls Creek in Western Australia. The project is within the Halls Creek Orogen and contains rock units of the Sally Downs Supersuite, Tickalara Metamorphics and Red Rock Formation. Three major faults, the Halls Creek Fault, Alice Downs Fault and Mount Ranford Fault pass through the project area.

Mineralisation occurrences recorded at Copper Springs have been documented to contain massive boxwork gossans with malachite encrustations and scattered remnant sulphides, or as malachite, azurite and goethite in vuggy quartz veins or shear zones. Hematite pseudomorphs after pyrite scattered through the country rock in several places have also been recorded.

Previous exploration is recorded across the area since the 1960’s and often the current project has been part of a much larger project area with previous exploration particularly focussing on diamonds and nickel-copper due to the proximity of the Savannah Nickel Mine (12km northwest) and Argyle Diamond Mine (75km north). Stream sediment sampling has largely covered the project area and some soil and rock chip samples are recorded along with two RC drill holes on the eastern project boundary drilled as a program testing the Azura Copper Project to the east. Previous exploration work is still being assessed but sampling of the known copper occurrences is yet to be located. Peak rock chip results located in the project area above 1% Cu in the NE project area include 4% Cu & 0.26g/t Au (sample TK500223), 3.4% Cu & 14.5g/t Ag (Sample TK651412) and 2.6% Cu (Sample TK500220) sampled by Thundelarra Exploration Ltd and 2.95% Cu (Sample 21BATSS5017) sampled by Battery Metals Limited.

Initial exploration is likely to include rock chip sampling and a geophysics program consisting of heliborne EM and ground gravity surveys to rapidly identify targets for drill testing.
