About the South West Arkansas Project

The South West Arkansas Project is located approximately 15 miles west of the City of Magnolia in southwestern Arkansas. The SWA Project’s Indicated and Inferred Mineral Resource of 1.4 Mt and 0.4 Mt lithium carbonate equivalent, respectively, has some of the highest reported lithium brine concentrations in North America, averaging above 400 mg/L. The recently announced results of a Preliminary Feasibility Study demonstrate robust economics (see press release dated 8 August 2023), assuming production of at least 30,000 tonnes per year of battery-quality lithium hydroxide beginning in 2027. Currently, the Project contemplates 91 full-time equivalent employees upon reaching commercial production.

The Company anticipates completing a FEED and Definitive Feasibility Study for the SWA Project in 2024 and beginning construction in 2025. The SWA Project is expected to reach commercial production in 2027, subject to continuing project definition, due diligence, project financing and receipt of future feasibility studies.
