Standard Lithium Files Definitive Feasibility Study for its First Commercial Lithium Extraction Plant – Phase 1A
EL DORADO, Ark., Oct. 18, 2023 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV:SLI) (NYSE American:SLI) (FRA:S5L), a leading near-commercial lithium company, today announced that the Definitive Feasibility Study (the “Report”) for its first commercial lithium project (“Phase 1A”) proposed to be located at the LANXESS South Plant has been filed.
With expected first production in 2026, Phase 1A is anticipated to be the first US-based lithium production project built in six decades, and the first commercial direct lithium extraction facility in North America with potential to double current United States lithium production from current levels.
Phase 1A will process lithium-rich brine currently flowing through existing infrastructure and represents production of only five percent of the total Measured and Indicated Resource of 2.8 Mt lithium carbonate equivalent (“LCE”)¹. The Definitive Feasibility Study demonstrates strong economics, assuming initial annual production of 5,700 tonnes, and an average annual production of 5,400 tonnes of battery-quality lithium carbonate over a 25-year operating life based on Proven and Probable Reserves of 208 Kt LCE at an average concentration of 217 mg/L. Phase 1A represents a modest 60-times scale up from the operational Demonstration Plant, which over a three-and-a-half-year period of effective and efficient lithium extraction, has used the same brine that will feed the proposed commercial plant. The Company expects to make a final investment decision for Phase 1A in the first half of 2024.
Standard Lithium intends to scale and replicate the development model for the Phase 1A project across its portfolio of projects in the Smackover Formation, including the South West Arkansas Project and highly prospective East Texas landholdings. The lithium concentrations of the Company’s projects tend to improve from east to west across the Smackover Formation. Most recently, East Texas drilling results delivered the new, highest grade lithium brine concentrations in North America that the Company is aware of, at 663 mg/L. Higher lithium concentrations paired with economies of scale through the advancement of multiple projects is expected to afford the Company a competitive advantage as it expands its footprint through the Smackover Formation.
Standard Lithium's filing of the Definitive Feasibility Study highlights its commitment to commercialize direct lithium extraction technology, starting with Phase 1A. This approach aims to unlock the resource potential of the Smackover Formation and address critical mineral needs in the U.S. sustainably and responsibly.
