Bradda Head Lithium Ltd. announced that it has commenced the second stage of metallurgical testwork at Basin East (BE), working towards producing a final battery quality lithium product, and associated economic co-products. Results of the work are expected in second half of 2022. Highlights: The company, which already has 305kt Lithium Carbonate equivalent (LCE) compliant JORC resource and an exploration target of up to 6Mt LCE at its Basin Project as identified by the Independent Consultant SRK, is now moving to produce larger quantities of lithiumpregnant leach solution (PLS) from its BE clay in Arizona.

The PLS will then be used to test Bradda's proposed flow sheet to produce lithium end chemicals as well as co-products which will potentially help to enhance the projects economics. The company has agreed terms with Resource Development Inc. (RDi) to carry out the work, which will take roughly 3 months to complete this phase. RDi will sample150kg of lithium clay from BE with a view to producing lithium sulphate in a PLS.

Bradda will then proceed to the production of lithium hydroxide or lithium carbonate from the PLS, depending on the processing route decided by Bradda. Bradda Head is looking into maximising future revenue from its Basin project (Basin) by looking into how to extract economic quantities of co-products, which will help to reduce the overall operating cost at its Basin Project. Once successful, the process will be optimised to apply the technology designed by Bradda on the PLS produced by this metallurgical testwork.

Results from this programme are due in second half of 2022, and if the proposed drill programmes at Basin provide a suitable increase in resource size, then Bradda will incorporate both into a PEA for 2023 (contractor not assigned), which would outline the route forward for Basin and demonstrate the projects economics. Having received positive results from the first stage of metallurgical testwork in January 2022 (See PR dated 12/01/2022), Bradda Head has commenced the second stage of metallurgical testwork at its BE asset, and has awarded the contract to carry out the work to well-known industry experts RDi. Based on recent concept tests, Bradda Head is proposing to carry out bulk tests on 150 kg of Li clay from Basin East to beneficiate it, then leach it, to generate enough lithium sulphate PLS to proceed further with impurity purification steps and then, once the Company is happy with the process, to proceed to production of lithium hydroxide or lithium carbonate.
