VANCOUVER, BC, April 13, 2021 /CNW/ -- 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,
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.
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. Prior Direct Lithium Extraction (DLE) technologies
have also struggled due to high water and energy consumption.
Lilac's new lithium extraction process enables rapid and low cost
extraction of lithium from brine with minimal water and energy. The
Company is evaluating both conventional evaporation and DLE to
determine the optimal process method for the HMN Li Project.
The next phase of test work will involve Lilac expanding test
work with a natural brine sample sourced from the HMN project. The
results will be analyzed under the supervision of a Qualified
Person along with third party ISO Certified laboratory
verification. This will provide confirmation of the results on
synthetic brine as well as an indication of expected costs for a
commercial scale process.
About Lithium South
LIS is focused on developing the HMN Li Project, located on the
Hombre Muerto Salar, the premier 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 U.S. $280 million. The
Company completed a Preliminary Economic Assessment of the HMN Li
Project in 2019, utilizing conventional evaporation extraction. The
Company is focused on evaluating alternative extraction methods for
the HMN Li Project and plans to become a leader in the application
of Direct Lithium Extraction technology at the project level.
