By leveraging the existing infrastructure and operational expertise of the largest brine processing facilities in North America, Standard Lithium (SLI) is leading a new wave of U.S. lithium production. Utilizing strategic partnerships, sustainable modern extraction and processing technologies, the Company is setting a new Standard for environmentally responsible lithium production in the U.S.

The Company’s two flagship projects, the Phase 1A Project and the South West Arkansas Project provide growth opportunities within the prolific Smackover Formation located in Southern Arkansas near the Louisiana border. Arkansas is a business-friendly environment with a rich history of chemical and energy production, with a deep talent pool, in the geographic center of the Electric Mobility Manufacturing Corridor. Combined, the two projects cover over 180,000 acres of unitized brine leases with a target production of 50,000+ tonnes of sustainably produced, battery quality lithium chemicals.

Phase 1A: First Commercial Lithium Extraction Plant
Most advanced is the Phase 1A Project, which is a brownfield project being developed in cooperation with the region’s largest brine operator, specialty chemical company LANXESS Corp. Standard Lithium has entered into agreements that allow the Company to leverage LANXESS existing, permitted processing infrastructure to develop it’s first commercial lithium extraction plant (link to press release). With this infrastructure head start and limited resource definition risks, the Company’s flagship project represents the fastest and most environmentally-friendly opportunity for new U.S. lithium production.

A Definitive Feasibility Study (“DFS”) was completed in the third quarter of 2023 (link to press release) for the Company’s first commercial lithium extraction plant project (“Phase 1A”) proposed to be located at the LANXESS South Plant. The DFS contemplates production of battery-quality lithium carbonate averaging 5,400 tpa over a 25-year operating life. Phase 1A represents production of approximately 5% of the Measured and Indicated Resources of 2.8 Mt lithium carbonate equivalent; the current Proven and Probable Reserve supports production over a 40-year operating life. The Company expects to make a Final Investment Decision in the first half of 2024, begin development and deliver first commercial production in 2026.

South West Arkansas Project
The South West Arkansas Project (“SWA”) is a greenfield project located approximately 15 miles to the west of the LANXESS facilities and the Company’s proposed Phase 1A Project. SWA is easily accessible via a paved highway and extensive regional infrastructure including water, power, gas and rail. A Preliminary Feasibility Study (“PFS”) was completed in the third quarter of 2023 (link to press release). The PFS contemplates production of battery-quality lithium hydroxide averaging 30,000 tpa over a 20-year operating life. The project includes an Indicated and Inferred Resource of 1.4 Mt and 0.4 Mt lithium carbonate equivalent, respectively, with an average lithium concentration of 437 mg/L that supports the potential for greater than 20 years of operation. The Company is targeting development to begin in 2025 and production to commence in 2027.
