Battery Grade Lithium Carbonate to be Produced at HMN Li Project

October 19, 2021 / Vancouver, BC / Lithium South Development Corporation (the “Company”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ) is pleased to announce that Eon Minerals of Miami Florida, through its laboratory located in Salta, Argentina, will be conducting test work to produce battery grade lithium carbonate from a bulk sample of brine to be recovered from the Hombre Muerto North Lithium Project (HMN Li Project), Argentina. Conventional process technology, based upon the proven evaporation extraction process of lithium will be utilized in this test phase.

The testing will begin with a pre-concentration process of 15 cubic meters of brine in ponds located at the project site.  Work will include liming, solid-liquid separation, removal of boron through Solvent Extraction, polishing of the brine, precipitation of primary lithium carbonate, bi-carbonation, polishing of the brine by Ion Exchange, resulting in a targeted-battery grade lithium carbonate product.  The process will also produce a lithium chloride solution with a targeted concentration up to 6% wt., which will be shipped to Chemphys Chengdu in China for further refinishing to their customer specifications.

The process test work will result in hard data for the design of a pilot test plant.  Recovery rates of lithium under salar conditions will provide the information required for a National Instrument 43-101 Technical Report.   The process test work will be supervised by Mr. Alex Mezei, a Qualified Person for the purposes of N.I. 43-101 and a recognized expert within the industry.

Company President, Adrian F.C. Hobkirk is quoted: “We are very pleased to move our project forward towards the pilot plant stage, as part of our evaluation of the best process to use in achieving lithium production at the HMN Li Project.”
