Standard Lithium and Equinor Joint Venture Receives Arkansas Approval for South West Arkansas Lithium Project

Standard Lithium Ltd. (NYSE American: SLI), through its 55:45 joint venture with Equinor known as Smackover Lithium, has received unanimous approval from the Arkansas Oil and Gas Commission for its Integration Application covering the Reynolds Brine Unit. This regulatory milestone ensures access to the 20,854-acre brine production area while protecting mineral owners' rights and de-risking the project's resource base. The South West Arkansas Project represents a significant advancement in domestic lithium production capabilities, with plans to produce 22,500 tonnes of battery-quality lithium carbonate annually beginning in 2028.

The approval finalizes a critical regulatory step for the joint venture's flagship project, building on previous unanimous AOGC approvals for unitization and a 2.5% lithium royalty—the first of its kind in Arkansas. This regulatory framework establishes important precedents for future lithium brine development in the region while ensuring proper compensation for mineral rights holders. The project's location in the Smackover Formation, recognized as a world-class lithium brine asset, positions it strategically within the growing North American battery supply chain.

The partnership between Standard Lithium and global energy leader Equinor combines specialized lithium development expertise with substantial energy industry experience, creating a formidable team for advancing large-scale lithium production. The joint venture's focus on sustainable development through scalable and fully integrated direct lithium extraction and purification processes addresses growing concerns about environmental impacts associated with traditional lithium mining methods. This approach aligns with increasing demand for responsibly sourced battery materials as the global transition to electric vehicles accelerates.

The project's advancement comes at a critical time for the North American battery supply chain, which faces increasing pressure to reduce dependence on foreign lithium sources. With annual production capacity equivalent to approximately 500,000 electric vehicle batteries, the SWA Project could significantly contribute to domestic battery manufacturing security. The project's location in southern Arkansas provides access to robust infrastructure, skilled labor, and streamlined permitting processes that support efficient development timelines.

For investors and industry stakeholders, the regulatory approval represents a substantial de-risking event for the project's development pathway. The unanimous nature of the AOGC decision underscores the project's compliance with state regulations and its alignment with Arkansas's economic development objectives.
