Global Lithium Resources Limited announced that it has commenced a detailed Metallurgical processing program for the Manna Lithium Project, located 100km east of Kalgoorlie in the Goldfields region. Leading resources engineering firm Wave International has been appointed to undertake the Study, which will define and test the metallurgical upgrade processes to produce an industry standard spodumene concentrate for the Manna Lithium Project. The Scoping Study that is currently underway for the Manna Lithium Project uses industry standards for spodumene concentrate recoveries to establish the parameters for the Study.

The outcomes of this Study will underpin actual recovery and grade information to be used in the subsequent Feasibility Study that is scheduled to commence in first quarter calendar year 2023, whilst also identifying key risks and opportunities. Wave, in conjunction with Global Lithium, will develop the forward work plan summarising the necessary engineering and plant requirements, through to project implementation. Wave is a development consultant with over 20 years of global experience in engineering, project strategy, feasibility studies, detailed design, project delivery and operational support.

has established significant capability in the battery minerals market across the lithium, vanadium, graphite and cobalt sectors and also have an established reputation for enabling successful commercialisation for junior and mid-tier battery mineral companies. The key deliverables of the Study include: Stage 0 ­ Characterisation: Sample receipt, preparation, and handling of core samples from GL1; Characterisation of samples into defined zones; Mineralogy on characterised samples; Comminution testwork on characterised samples. Stage 1 ­ Preliminary Heavy Liquid Separation (HLS) and flotation: HLS testwork on characterised samples; Whole of Ore (WOO) flotation testwork on characterised samples; Interim report, including analysis and recommendations for Stage 2. Stage 2 ­HLS /or flotation development: Following analysis of the preliminary HLS results, Stage 2 testwork will be undertaken on a more defined flowsheet and will comprise the following; HLS testwork on samples; Mica removal via batch reflux classifying; Dense Media Separation (DMS) testwork at selected crush size; Magnetic separation on DMS concentrate; Further flotation development; Interim report, including analysis and recommendations for preferred flowsheet configuration and key process design criteria for engineering development.

Stage 3 ­ Variability: Sample receipt, preparation, and handling of core samples from throughout the Manna Project; HLS testwork on preferred regime form previous stages (unless ruled out by previous testwork); Flotation testwork on selected samples on preferred regime from previous stages; Additional testwork iterations to understand adjustments required to the flow sheet; Process design criteria to achieve acceptable results. Stage 4 ­ Final report, including any recommendations and final flow sheet.
