Standard Lithium and Equinor move toward a year-end investment decision on the first large-scale lithium site in the Smackover Formation, targeting 2029 output despite falling prices.
MoneyTurkey Commodities Desk | 3 November 2026
Key points
- Standard Lithium is targeting a year-end investment decision on its $1.45-billion capex South West Arkansas project, which would produce 22,500 tonnes of battery-grade lithium carbonate annually.
- The Smackover Lithium joint venture holds 1.18 million measured and indicated tonnes of LCE at SWA and 1.77 million indicated tonnes at Franklin, with lithium concentrations of 442-572 mg per litre.
Standard Lithium is advancing its South West Arkansas project toward a final investment decision by year-end, with construction slated to begin in early 2027 and first output in 2029. The $1.45-billion direct lithium extraction facility would mark the first large-scale lithium production in the Smackover Formation, a region long known for oil, gas and bromine output. The company and partner Equinor are positioning the venture as a catalyst for regional development, with plans to reach at least 100,000 tonnes per year across their portfolio within a decade.
What happened
Standard Lithium, operator of the Smackover Lithium joint venture with Equinor, is preparing to decide on full funding for the South West Arkansas project by the end of this year. The site would extract lithium from brines in the Smackover Formation, which stretches from central Texas to the Florida panhandle and contains some of the highest lithium concentrations outside South America.
The first stage of SWA is designed to produce 22,500 tonnes per year of battery-grade lithium carbonate over a 20-year life, with potential for later expansion. A separate Franklin project in Texas holds a preliminary economic assessment for up to 70,000 tonnes of lithium carbonate equivalent annually, with initial output possible in the early 2030s.
Standard owns 55 percent of the joint venture and acts as operator, while Equinor holds 45 percent. The partners cite Equinor’s oil and gas subsurface expertise as complementary to brine handling and lithium extraction.
Resource base and timeline
A September 2025 resource estimate shows SWA contains 1.18 million measured and indicated tonnes of lithium carbonate equivalent at an average grade of 442 milligrams per litre, plus 278,000 inferred tonnes at 355 mg per litre. Franklin holds 1.77 million indicated tonnes at 562 mg per litre and 2.13 million inferred tonnes at 572 mg per litre, according to a July resource.
Standard’s vice president of government affairs, Jesse Edmondson, told The Northern Miner that the Smackover portfolio could support 100,000 to 150,000 tonnes per year within ten years. The company’s immediate focus is securing the SWA investment decision and moving into construction.
Why it matters
U.S. authorities are seeking to reduce reliance on imported lithium, and the Smackover Formation has drawn interest from oil majors including ExxonMobil, Chevron and Occidental Petroleum. These companies see overlap between their existing drilling, brine handling and subsurface skills and the requirements of lithium extraction.
BMO Capital Markets analyst Raj Ray noted that Standard is well positioned as an early mover in the region and that Equinor’s expertise will support project development. The push comes even as lithium prices have fallen, with developers betting that domestic supply security and geological advantages will support long-term output growth.
What to watch
- Year-end investment decision on SWA project
- Financing terms and construction start in early 2027
- Progress on Franklin preliminary economic assessment
- Further interest from oil majors in Smackover brines
