VANCOUVER, BC, July 7, 2022
/CNW/ -- Lithium South Development
Corporation (the "Company") (TSX-V: LIS) (OTCQB: LISMF)
(Frankfurt: OGPQ) is pleased to provide an update
on process test work currently underway at the Hombre Muerto North
Lithium Project (HMN Li Project), located in Salta, Argentina. The purpose of the test
work is to validate evaporation as a viable concentration method in
preparation for a potential on site pilot plant and subsequent
Feasibility Study. The work is being performed by Eon Minerals a
Delaware based company with
laboratory facilities in Salta, Argentina. The work was supervised by
Alex Mezei, P. Eng., a Qualified
Person under N.I. 43-101.
Lithium South Development Corporation
is pleased to announce the results of the testwork to
date aiming to demonstrate the possibility of producing battery
grade lithium carbonate.
Accordingly, a representative Hombre Muerto North ("HMN") salar
brine sample of 7,359 L (8.874 t) containing 874 mg/L Li+ was
subjected to pre-concentration by evaporation at the site. About
92% of the lithium was recovered in 600 L (744 kg) preconcentrated
brine assaying about 6.8 g/L Li+. Subsequent liming followed by
concentration-evaporation yielded about 60 L of brine (80 kg)
assaying 32.7 g/L Li+. The overall lithium recovery was 60%
compared to 51% recovery predicted in the 2019 NI 43-101 Technical
Report. Current work on this sample aims to increase the lithium
concentration while assessing the possible impact on purity and
recovery. The interim maximum lithium concentration attained to
date was 47.8 g/L Li.
The next step in the process test work will be to advance the
concentration process aiming for 6% Li in the final brine,
rendering it potentially suitable for the production of Lithium
Chloride, a marketable commodity. Following this milestone, the
ongoing-parallel testwork aiming for the production of battery
grade lithium carbonate will further confirm the suitability of
evaporation as a concentration method for the lithium contained in
the Hombre Muerto North brine.

About Lithium South
Lithium South is focused on developing the Hombre Muerto North
Lithium Project (HMN Li Project), located on the Hombre Muerto
Salar, a major lithium-producing salar in Argentina. The property is adjacent to land
under development by the Korean multinational corporation POSCO,
which acquired the ground from Galaxy Resources Ltd. for US
$280 million. The Company
completed a Preliminary Economic Assessment of the HMN Li Project
in 2019, utilizing conventional evaporation extraction.
