Cobra’s Western Eyre Peninsula Project in South Australia consists of three granted tenements (EL 6966, 6967 & 6806) and one tenement application covering a total of 3,895 km2.

The tenement package covers some ~2,000 km2 of the Narlaby, Yaninee and Thulga palaeochannel systems which are considered prospective for both sandstone-hosted uranium and for further ionic REE mineralisation as defined at the Boland Project.

Similar geological mechanisms dictate REE and uranium mobilisation through the palaeochannel systems where economic occurrences may be recoverable through low-cost, low-disturbance ISR mining.


  • Previous uranium exploration has defined palaeochannel hosted roll-front mineralisation with grades exceeding >250 ppm U3O8 at a number of prospects across the Narlaby, Corrobinnie, Yaninee, and Thurlga palaeochannels
  • EL 6967 (“Pureba”) covers the eastern roll-front mineralisation of the Yarranna South East prospect with significant historical results of between 209 ppm and 708 ppm U3O8 defining roll-front mineralisation across a >4km roll-front
  • EL 6806 (“Yaninee”) covers the Kattata uranium prospect hosted by sediments of the Yaninee Palaeochannel, located ~30km southwest of the Boland Project

Next Steps

Cobra’s exploration strategy to demonstrate scale to the Boland Project incorporates uranium testing and targeting, because the controls that drive ionic REE mineralisation are likely to be maximised in front of REDOX (roll-front) boundaries. Further work will include:

  • Confirming the regional scalability of ionic REE mineralisation within the Narlaby, Yarranna, Corrobinnie and Yaninee palaeochannels.
  • Reviewing historical drillhole data including downhole geophysics (gamma)
  • Improving roll-front models and identifying roll-front extensions for the Yarranna South East prospect
  • Further re-assaying of historical samples to validate historical uranium results
  • Evaluate spatial relationships between uranium and potential ionic REE mineralisation to advance dual resource growth capable of being recovered through ISR mining
  • Define and prioritise targets for follow-up AC drilling subsequent to the company gaining native title, landholder, and regulatory approvals
