Key Highlights • Ongoing optimisation testwork on the Manna Lithium Project Whole-of-Ore (WOO) flotationflowsheet achieving excellent improvements in lithia recovery
• Optimisation testwork focussing on magnetic separation and mica pre-flotation stages hasincreased Li2O recoveries from 70% to 75% for spodumene composite ore samples.
• Further optimisation testwork is pursuing improvements in recovery via reduced slimes losses,reprocessing of magnetic separation tails, and engaging with reagent suppliers to optimisespodumene flotation circuit operating conditions
• Testwork results continuing to achieve >5.5% Li2O spodumene concentrate (SC), with ongoingoptimisation targeting grade increases• A total of 66 flotation tests have been completed to-date producing a SC product of5.6 - 6.5% Li2O and 0.4 - 0.8% Fe2O3
• Preparations for the next phase of ore sorting testwork are well advanced with trials imminent atSteinert’s industrial testwork facility in Perth
• This increase in lithia recovery will have a positive impact on project economics at Manna
