**Smackover Lithium Receives Key Final Integration Approval from the Arkansas Oil and Gas Commission for South West Arkansas Project**

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.

Unitization of the Reynolds brine production area covering 20,854 acres was unanimously approved on April 24<sup>th</sup> by the AOGC, and a 2.5% lithium royalty was subsequently unanimously approved on May 29<sup>th</sup>, representing the first such royalty for lithium from brine in Arkansas. The Project has plans for initial annual capacity of 22,500 tonnes of battery-quality lithium carbonate, with first production expected in 2028.

*"We thank the AOGC for its attention and support in granting integration approval for our Project,"* said Standard Lithium's President and COO, Dr. Andy Robinson. *"With this key regulatory milestone behind us, we can continue to push towards a Final Investment Decision for the SWA Project as soon as practical."*

*"Arkansas continues to be focused on driving economic growth through regulatory certainty,"* said Allison Kennedy Thurmond, VP for US Lithium at Equinor. *"The unanimous approvals from AOGC for our unitization, royalty and now integration applications provide confidence for the SWA Project to move forward."*
