Standard Lithium Provides Update on Phase 1A Commercialization Progress, Announces Engagement of Citi for Strategic Financing and Partnerships

EL DORADO, Ark., Dec. 04, 2023 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLI) (NYSE American: SLI) (FRA: S5L), a leading near-commercial lithium development company, is pleased to provide an update on the commercial progress of its Phase 1A Project at LANXESS' South Plant near El Dorado, Arkansas. The Company has engaged Citi to facilitate strategic financing and partnership options for the Phase 1A Project, as well as for advancing the broader South West Arkansas project and the Company’s initiatives in East Texas.

In line with its strategic focus on core operations, LANXESS Corporation (“LANXESS”) has communicated its plans to commercialize its role in the Phase 1A Project alongside Standard Lithium. The cooperative framework is to include a brine supply and disposal agreement, a lease agreement for the production facility site, and the provisioning of certain infrastructure services. Details of the future cooperation are the subject of ongoing negotiations. These agreements will form the basis of the operational framework for the Phase 1A Project.

With the Phase 1A Project’s ownership and operational structure now clearly defined, Standard Lithium is well-placed to optimize project partnerships and structure off-take agreements that capture the full potential value of the project. With this increased clarity, supported by Citi for strategic financing and partnerships and BNP Paribas for debt financing and off-take negotiations, the Company is now positioned to accelerate project development and execute on its strategy to unlock the full potential of its Smackover resources.

The recent U.S. Treasury Department's announcement on the Inflation Reduction Act’s Foreign Entity of Concern (FEOC) underscores the importance of domestic critical minerals for EV batteries. This strengthens the appeal of Standard Lithium's Smackover projects, given their U.S. location and potential to provide a secure, local supply of lithium in line with the Act's objectives, highlighting Standard Lithium's advantageous position in a market seeking domestic sources for these crucial materials.

This opportunity leverages the proven and replicable Direct Lithium Extraction (“DLE”) process, tailored for the Smackover Formation. Developed over three and a half years and demonstrated at the South Plant, this DLE technology is designed for replicability across the Company's Smackover projects and is currently the only DLE process in the industry ready for commercial scaling.

The Phase 1A Project is detailed in the Company's recently reported Definitive Feasibility Study (“DFS”). The DFS anticipates the first production of battery-quality lithium carbonate in 2026, using direct lithium extraction from Smackover brine currently produced by LANXESS from their South Brine Unit. The DFS projects an average annual production of 5,400 tonnes per annum (tpa) over the operating life with peak annual production of 5,700 tpa and a 25-year minimum operating life. Proven and Probable Reserves of 208 kt lithium carbonate equivalent (LCE) at an average concentration of 217 mg/L over the entire mine-life support up to 40 years of operations.
