LILAC
SOLUTIONS ACHIEVES
99% LITHIUM RECOVERY WITH
ION
EXCHANGE PROCESS
Vancouver,
British Columbia, Canada -- April 13, 2021 -- InvestorsHub NewsWire
-- 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.
