Standard Lithium hits key milestones at Arkansas plant, processing 1M barrels of brine with zero safety incidents.

Standard Lithium has achieved major operational milestones at its Arkansas Demonstration Plant, processing 1 million barrels of real-time brine from the Smackover Formation and completing over 15,000 cycles of its direct lithium extraction (DLE) process. The plant demonstrated lithium recovery rates above 95% and contaminant rejection over 99%, supporting the scalability of its technology for the South West Arkansas Project. With 340,000 man hours logged without any safety incidents, the facility continues to optimize processes and train staff, strengthening the company's position for a Final Investment Decision and sustainable lithium production in the U.S.
