Highlights

  • The Flinders Project is highly prospective for IOCG mineralisation with high-grade copper and gold sample results obtained recently from outcropping mineralised breccias over a strike of at least 6.4km
  • Further strike potential of up to 15km identified by reprocessing and modelling of government magnetics
  • Long strike, high-grade results and geochemical signature indicates potential for a large IOCG system
  • The Flinders Project lies at the intersection of two regional structural corridors which host the Olympic Dam and Carrapateena IOCG’s (NW trending) and Beltana Zinc and Leigh Creek Copper (NE trending), and sits only 80km from Carrapateena and 150km from Olympic Dam
  • Significant upside potential with limited modern exploration and multiple high-grade targets

Project overview

The Flinders Project hosts a highly prospective copper-gold target portfolio, in the same structural setting as the giant Olympic Dam (9,080Mt @ 0.87% Cu, 0.32g/t Au and 0.27kg/t U3O8) and Carrapateena (970Mt @ 0.5% Cu and 0.2g/t Au) deposits, with significant outcropping, high grade mineralisation exposed on the lease. The Flinders Project is located 80km from Carrapateena and 150km from Olympic Dam, with power and rail on the lease.

Flinders Project Prospects

  • Woolshed – Mineralised breccia with high-grade copper, gold and silver mineralisation associated with a 3km x 1.6km linear magnetic anomaly.
  • Main Lode – Mineralised breccia with a history of high-grade copper mining – significant copper and cobalt mineralisation with anomalous gold and silver identified.
  • Jenkins North – A large 2.6 x 1.2 km magnetic anomaly known to contain mineralised breccias similar to the Woolshed breccia which hosts high-grade copper and gold
  • Jenkins South – A large 3.6 x 1.2km magnetic anomaly adjacent the Jenkins North Anomaly with similar features to Jenkins North
  • Mt Stephen – A 1.6 x 1km magnetic anomaly associated with the flexture point of the Mt Stephen’s Thrust which hosts Woolshed copper-gold mineralisation further north
  • Rainy Day – Mineralised breccia with an unrecorded artisanal copper mining history and rock-chip results pending
  • Rambla – Sediment hosted, with copper and silver mineralisation associated with a 1.8km striking white-rock alteration feature

Project History

Various artisanal and small-scale copper mining operations occurred within the Warrakimbo Ranges where high-grade copper mineralisation was first noted in the late 1800’s and continued intermittently for 130 years.

Historic exploration failed to recognise the potential connectivity between the outcropping mineralisation in the range and the IOCG affinity of the geochemistry. Only 1 shallow hole has been sunk into Main Lode which intersected mineralised breccia at depth however was never assayed nor followed up. Two shallow holes drilled into the Jenkins North mag anomaly intersected hematite and magnetite altered mafic breccia resembling the Woolshed breccia which hosts high-grade copper and gold. Geophysical modelling indicates the historic drilling fell short of reaching the magnetic source which extends to over a kilometre depth from 4 meters, as a pipe-like feature.

Previous exploration excluded highly detailed geophysics and surface sampling programs which will be an initial focus of our exploration program.

Exploration Plan – Warrakimbo Ranges IOCG Targets

  • Detailed rock-chip, streams and soils program
  • Reprocessing of government geophysics data
  • High-resolution gravity survey to identify non-magnetic hematite-IOCG targets like Main Lode and Rainy Day prospects
  • Commence drill testing of priority targets
