Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLI) (NYSE American: SLI) (FRA: S5L), a leading near-commercial lithium company, is pleased to announce that its Carbon Capture Pilot Plant has been successfully installed at the final testing location in southern Arkansas (see news release dated 14th September 2021). The Carbon Capture Pilot Plant will assess the technical and financial viability of capturing CO2 directly from natural gas burning flue-gas streams, and will inform how Standard Lithium can use technology to minimize CO2 emissions at future production facilities.

Dr. Andy Robinson, President and COO of Standard Lithium commented, “Standard Lithium is committed to ushering in a new generation of sustainable mineral extraction by exploring novel, cutting-edge technologies designed to minimize carbon emissions. We look forward to testing this innovative carbon capture technology to better understand how Standard Lithium can engage in the most sustainable production processes, while integrating low-carbon lithium products into North America’s energy transition supply chain.”

This pilot testing supports the Company’s wider Carbon Capture Utilization and Sequestration (“CCUS”) strategy, and will be integrated with ongoing work to understand how captured carbon can be utilized in the Company’s lithium brine processing flowsheet, and potentially in permanent geological sequestration (see news release dated 13th July 2022). Standard Lithium is one of the owners of this novel carbon capture technology via a $2.5 million equity investment in Aqualung Carbon Capture AS (“Aqualung”) (see news release dated 12th May 2022).

The Carbon Capture Pilot Plant was designed and constructed in the United Kingdom by Standard Lithium’s partner, Aqualung. Following initial commissioning and testing with a CO2-rich flue-gas stream, the plant was then shipped to the Gulf Coast and installed at the final testing location, a natural gas processing site in southern Arkansas that is owned and operated by Mission Creek Resources LLC (“Mission Creek”). Refer to Figure 1 below for a view inside the Carbon Capture Pilot Plant and to Figure 2 for a view of the initial installation.

About Standard Lithium Ltd.

Standard Lithium is a leading near-commercial lithium development company with a portfolio of projects in process. The Company’s flagship projects, the LANXESS Property Project and the South West Arkansas Project, are located in southern Arkansas near the Louisiana stateline. The Company is focused on the evaluation and testing of commercial lithium extraction and purification from brine sourced from approximately 180,000 acres of unitized leases across these two projects. The Company operates a first-of-a-kind industrial-scale Direct Lithium Extraction (DLE) Demonstration Plant at the LANXESS Property Project. The scalable, environmentally friendly process eliminates the use of evaporation ponds, reduces processing time from months to hours and greatly increases the effective recovery of lithium. A Definitive Feasibility Study (DFS) and Front-End Engineering Study (FEED) for Phase 1A of the LANXESS Property Project commenced in September 2022. A Preliminary Feasibility Study (PFS) of the South West Arkansas Project commenced in May 2022. The Company is also pursuing the resource development of approximately 45,000 acres of mineral leases located in the Mojave Desert in San Bernardino County, California.

Standard Lithium is jointly listed on the TSX Venture Exchange and the NYSE American under the trading symbol “SLI”; and on the Frankfurt Stock Exchange under the symbol “S5L”. Please visit the Company’s website at www.standardlithium.com.
