About the South West Arkansas Project

The South West Arkansas Project (“SWA” or the “Project”) is located in Lafayette and Columbia Counties, Arkansas, and is being developed in partnership with Equinor, which holds a 45% non-operating interest in the Project. SWA’s Indicated and Inferred Mineral Resource of 1.4 Mt and 0.4 Mt lithium carbonate equivalent, with an average lithium concentration of 437 mg/L, has some of the highest reported lithium brine concentrations in North America. The design engineers working on behalf of the Company are developing Front-end Engineering Design (“FEED”) and a Definitive Feasibility Study (“DFS”) that contemplates total production of up to 45,000 tonnes per annum of lithium carbonate, to be developed in two phases of 22,500 tonnes per annum each.

SWA’s direct lithium extraction and lithium carbonate facilities are planned to be located on a 118-acre property in rural Lafayette County, approximately 7 miles south of Lewisville, Arkansas. The Project is expected to create up to 300 construction jobs and 100 direct jobs and dedicate millions of dollars to community impact efforts that will benefit the local area through infrastructure improvements, community health initiatives, educational partnerships, and workforce development programs.

The Company completed a Preliminary Feasibility Study for the project in 2023, and a DFS and FEED are currently underway.
