Status: DFS completed for Uley 2 Stage 1
Location: Eyre Peninsula, SA; 20km west-south-west of Port Lincoln
Government approvals: All approvals obtained pursuant to Program for Environment Protection and Rehabilitation
Scheduled start of development: Q2 2022
Stage 1 mine life: 12 years
Stage 1 production level: Uley 2 processing plant will produce a minimum of 55,000 tonnes of high purity coarse flake.
Graphite mineral processing: Liberation of graphite particles through crushing and grinding followed by floatation and polishing sections. Multi-stage polishing critical to enhanced flake graphite recoveries and maximising purity and coarse flake size.
Graphite beneficiated to 99%: Following mineral processing, graphite flakes will be beneficiated to 99% utilising Sunlands Co. technology. DFS for beneficiate process to be completed by mid 2022.
Offtake agreements in place: Joint Venture arrangement with The Sunlands Company Pty Ltd (thermal storage applications) approx. 20% of annual production.
