Smackover Lithium, a joint venture (JV) between Standard Lithium and Norwegian energy company Equinor has completed sampling from its newest exploration well in the South West Arkansas (SWA) Project area and has recorded the highest lithium concentration to date at 616 mg/L lithium in brine.

The Lester well was completed in the second quarter of this year and concludes all sub-surface exploration activities for Phase 1 of the SWA Project.

Sampling of brines and subsequent analysis of the brine by an independent third-party certified laboratory demonstrated higher than expected lithium concentrations in the Lester brine. The average lithium concentration from three brine samples was 582 mg/L.

“We completed this final well in a part of the project area where we expected the lithium concentration to be approximately 500 mg/L, so we’re encouraged with these latest sampling results that show the highest lithium concentrations in the whole SWA Project area at a maximum of 616 mg/L,” said Dr. Andy Robinson, President and COO of Standard Lithium. “With all of the fieldwork complete, the joint Smackover Lithium team is working to complete the FEED study. A Definitive Feasibility Study is expected later in the third quarter of this year and a Final Investment Decision targeted by year-end 2025.”
