NEWS: Standard Lithium Completes Installation of Final Modules of Its “LiSTR” Direct Lithium Extraction Demonstration Plant at the Arkansas Project Site

Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLL) (OTCQX: STLHF) (FRA: S5L), is pleased to announce that the final modules of the Company’s “LiSTR” direct lithium extraction Demonstration Plant have been transported to and are currently being installed at Lanxess’ South Plant facility in southern Arkansas (the “Site”).

Fabrication and initial QA/QC testing of the final Phase 3 Modules of the Demonstration Plant was completed in early October, and the modules (8 modules in this final Phase 3, plus spare parts) were separated and shipped to the Site.  The Phase 3 modules have now arrived at the Site and are in the process of being installed and connected. Current photos of the Demonstration Plant Site, showing the installed modules in Figures 1 and 2 below.

Once all the modules are installed, the project engineers and contractors will continue connecting and testing all the modules and installing the tie-ins to utilities and services.  The commissioning process is scheduled to begin in November.

The Demonstration Plant is designed to continuously process an input tailbrine flow of 50 gallons per minute (gpm; or 11.4 m3/hr) from the Lanxess South Plant, which is equivalent to an annual production of between 100-150 tonnes per annum Lithium Carbonate Equivalent (LCE). The Demonstration Plant is based on Standard Lithium’s proprietary LiSTR technology, that uses a solid sorbent material to selectively extract lithium from Lanxess’ tailbrine. 

The environmentally friendly process eliminates the use of evaporation ponds, reduces processing time from months to hours and greatly increases the effective recovery of lithium.

Dr Andy Robinson, Standard Lithium President and COO, commented “our roll-out of the LiSTR direct lithium extraction Demonstration Plant continues to be executed on-schedule, and Standard Lithium would like to thank our project partners for all their efforts in keeping this Project constantly moving forward.  We now have a full project team in place, and plant operators are currently undergoing process-specific training.  We look forward to beginning the commissioning phase in November and starting the next exciting step of this Project.
