Eon Minerals Inc. to Evaluate HMN Brine using Direct Lithium Extraction Technology

May 17, 2021 / Vancouver, BC / Lithium South Development Corporation (the “Company”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt OGPQ) is pleased to provide an update on the continued evaluation of Direct Lithium Extraction (DLE) technology for its Hombre Muerto North Lithium Project (HMN Li Project), located in Salta Province, Argentina.

LIS is working with Eon Minerals Inc. (EMI), a Miami Florida based technology company. EMI is headed by Mr. Fernando Villarroel, Vice-President and a director of the Company. The EMI process is an innovative absorbent consisting of specific nanoparticles and is currently patent pending at the United States Patent Office. A 2,000-liter brine sample has been received at the EMI laboratory in Salta, and test work is anticipated to begin this week.

A first phase in evaluation of the process will be to analyze a computational chemistry brine with the absorbent to determine the reliability and duration of the absorbent. The second phase will involve test work utilizing a natural brine sample taken from the 2,000-liter reserve. The testing will be conducted under the supervision of a Qualified Person along with third party ISO Certified laboratory verification.

LIS is now utilizing four options to determine the optimal plan for the development of the project. Three DLE processes are now under evaluation, and the Company is continuing to move forward with test work utilizing conventional evaporation.
