Smackover Lithium Releases Maiden Inferred Resource for its Franklin Project Comprising a Portion of Significant Brine Position in East Texas

LEWISVILLE, Ark., Sept. 24, 2025 (GLOBE NEWSWIRE) -- Smackover Lithium, a Joint Venture (“JV”) between Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV:SLI.VN) (NYSE.A: SLI) and Equinor (“Equinor”) (OSE:EQNR) (NYSE:EQNR), announced today a maiden inferred resource for its Franklin Project (the “Project”) in the northeast region of Texas, USA. This report for the JV’s first project in the East Texas region of the Smackover highlights the size and quality of its brine position. It contains the highest reported lithium-in-brine grades in North America and marks a key step towards the ultimate goal of reaching production of over 100,000 tonnes of lithium chemicals per year in Texas through multiple phases. This goal is further supported by two additional projects that the JV is planning to develop in East Texas that roughly triples the size of the portfolio area in the state.
