09:47 AM EST - Lithium South Development Corporation : Provided an update on the continued evaluation of Direct Lithium Extraction (DLE) technology for its Hombre Muerto North Lithium Project, located in Salta Province , Argentina. Lilac Solutions of Oakland California, a lithium extraction company providing technology and services to lithium brine developers, has advised the Company that they have completed their own testing using their patented Ion Exchange (IX) media on a synthetic sample of the HMN Li Project brine, identical in chemical composition to that contained within the projects NI 43-101 Preliminary Economic Assessment previously filed by the Company. The results produced a lithium chloride eluate solution recovering 99% of the lithium with very low reagent consumption. The eluate composition showed high purity and low total dissolved solids. This eluate would be concentrated using reverse osmosis and mechanical evaporation to feed a conventional plant for the production of lithium hydroxide or lithium carbonate. Both acid and base reagents used in the process can be produced on site using a chlor-alkali system. Water consumption was 18 metric tonnes for each tonne of Lithium Carbonate Equivalent produced. The results and values reported were provided by Lilac Solutions and were not conducted in an ISO Certified Laboratory under the supervision of a Qualified Person, and the results presented have not been verified by a Qualified Person.
