LEWISVILLE, Ark., Oct. 30, 2025 (GLOBE NEWSWIRE) -- Smackover Lithium, a 55:45 owned Joint Venture (“JV”) between Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLI) (NYSE.A: SLI) and Equinor (“Equinor”), is pleased to announce unanimous approval from the Arkansas Oil and Gas Commission (“AOGC”) for its Integration Application for the Reynolds Brine Unit where the initial commercial phase of the JV’s flagship South West Arkansas Project (the “Project” or “SWA Project”) is planned to be developed.   Integration is the formal process which amalgamates any non-leased mineral interests into an approved brine production unit, ensuring the operator’s access to the brine while protecting the correlative rights of mineral owners.   This final AOGC approval is a key de-risking step providing certainty on the resource underpinning the Project.
