VANCOUVER, BC, April 20, 2021 /PRNewswire/ -- Lithium South Development Corporation (the "Company") (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ) is pleased announce it has completed a bulk brine sample at the Hombre Muerto North Lithium Project (HMN Li Project), located in Salta Province, Argentina. The purpose of the program is to provide Chemphys Chengdu of Chengdu China, and Lilac Solutions, of Oakland, California, a large brine sample for Direct Lithium Extraction test work. The well head located on the Tramo Claim block was opened and run for 12 hours, and then three 2,000-liter brine samples were obtained. The samples have been processed through Salta, Argentina, and are now in shipment. All work was completed under the supervision of Mr. William Feyerabend, a Qualified Person under NI 43-101.

Conventional lithium extraction involves the construction of large evaporation ponds to concentrate the lithium contained in the raw brine. The costs of pond construction is significant, the environmental footprint is large, and the production lead time is approximately 18 months. These factors contribute to the challenges of applying the traditional evaporation process to meet increasing market demand. The Company is evaluating both conventional evaporation and DLE to determine the optimal process method for the HMN Li Project.
