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

VANCOUVER, Jan. 09, 2019 - 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.
