Standard Lithium Ltd. JV Achieves Record Lithium Grades at Smackover Project

Standard Lithium Ltd. (NYSE American: SLI), in collaboration with Equinor through their joint venture Smackover Lithium, has announced a significant milestone in lithium brine exploration at the South West Arkansas (SWA) Project. The completion of sampling from the Lester well revealed the highest lithium concentration recorded to date at 616 mg/L, with average concentrations from three samples reaching 582 mg/L. This achievement concludes the sub-surface exploration activities for Phase 1 of the project.

The joint venture team is now focusing on advancing its Front-End Engineering Design (FEED) study, with expectations to complete a Definitive Feasibility Study by the third quarter of 2025. The aim is to reach a Final Investment Decision by the end of the same year. This progress underscores the potential of the Smackover Formation as a world-class lithium-brine asset, particularly in Arkansas and Texas, where Standard Lithium Ltd. is concentrating its efforts.

The significance of this development lies in the growing demand for lithium, a critical component in the production of batteries for electric vehicles and renewable energy storage systems. The record-breaking lithium grades at the SWA Project not only highlight the quality of the resource but also the efficiency of Standard Lithium Ltd.'s direct lithium extraction (DLE) and purification process. This method is pivotal for achieving sustainable, commercial-scale lithium production, aligning with global efforts to transition towards cleaner energy sources.
