Standard Lithium Make First Pilot-Scale Battery Quality Lithium Carbonate, Engages Investor Relations Firm, LHA

Metallurgy & Processing Marketing Announcement

Standard Lithium Make First Pilot-Scale Battery Quality Lithium Carbonate, Engages

Investor Relations Firm, LHA

09 January 2019 – Vancouver, BC – Standard Lithium Ltd.(“Standard Lithium” or the

“Company”) (TSXV: SLL) (OTC-Nasdaq Intl. Designation: STLHF) (FRA: S5L), announced that

the Company has produced its first quantity of battery quality (>99.56% purity) lithium

carbonate.

Dr. Andy Robinson, President and COO of Standard Lithium, commented, “We continue to be

very pleased with the performance of our prototype pilot. Whilst we had previously made

‘battery quality’ carbonate at bench scale using our proprietary technology, we consider it an

important milestone that we can achieve the same very high levels of purity at the larger scale

of our prototype pilot. This has provided Standard Lithium, our Technical Team and our design

partners with all the confidence needed to commence detailed design on the main crystallisation

pilot plant, and this work is now ongoing.”

The battery quality lithium carbonate was produced at the Company’s prototype Lithium

Carbonate Crystallisation Pilot Plant operated by Saltworks Technologies Inc., at their facility in

Richmond, British Columbia, Canada. The Crystallisation Pilot Plant is based on Standard

Lithium’s proprietary technology, and information regarding its commissioning and first results

were reported in news dated December 12, 2018 . As previously reported, the synthetic feed

solution to the crystallisation process was relatively ‘impure’; similar to, but less pure than that

produced by the Company’s Lithium Extraction Process (as per ongoing testing at the

Company’s mini-pilot plant in Ontario).

Lithium Carbonate Crystallisation Pilot Plant

The prototype crystallisation plant was operated as a two-stage crystallisation process. The

initial solids produced from the first run (as previously reported December 12, 2018), were re-

solubilised and crystallised a second time. The solids produced from this second run (second

stage as reported here) were then hot-washed, filtered and dried. The resulting lithium

carbonate crystals were a fine free-flowing powder and were >99.56% pure. Despite the fact

that the synthetic starting solution had more impurities than are anticipated to be present in the

solution the upstream process will produce, lithium carbonate purity targets were met, giving a

measure of comfort that the crystallisation process is robust. Additional optimisation is now

being performed, and the technical team will also be adjusting the composition of the input feed

stream so as to optimise how the two parts of Standard Lithium’s proprietary technologies work

together.

stage; resource, political & geographic, regulatory & permitting, and by leveraging advances in

lithium extraction technologies and processes. The Company’s flagship project is located in

southern Arkansas, where it is engaged in the testing and proving of the commercial viability of

lithium extraction from over 150,000 acres of permitted brine operations utilising the Company’s

proprietary selective extraction technology. The Company is also pursuing the resource

development of over 30,000 acres of separate brine leases located in southwestern Arkansas

and approximately 45,000 acres of mineral leases located in the Mojave Desert in San

Bernardino County, California.
