SEC filingStandard Lithium announced major operational milestones at its Arkansas Demonstration Plant, including processing 1 million barrels of real brine and completing 15,000 DLE cycles with high recovery rates.
Standard Lithium's Demonstration Plant in El Dorado, Arkansas, has achieved critical operational benchmarks that validate the scalability and reliability of its direct lithium extraction (DLE) technology. Processing 1 million barrels of real-time brine from the Smackover Formation provides a robust dataset for optimizing the full brine-to-lithium carbonate flowsheet, directly supporting the South West Arkansas (SWA) Project's planned 22,500 tonnes annual capacity. The 15,000 successful DLE cycles confirm key performance metrics of over 95% lithium recovery and 99% rejection of contaminants, using the same process destined for commercial deployment. This six-year track record, encompassing 340,000 man hours without safety incidents, highlights the team's expertise and the facility's continuous operation as the only real-brine processing plant of its kind in the region. These milestones de-risk commissioning and engineering for the SWA Project, positioning Standard Lithium as the first-mover with a shovel-ready initiative nearing Final Investment Decision. Ongoing operations will further refine process flowsheet, gather data, train personnel, and inform sustainable lithium production strategies in partnership with Equinor.
