Standard Lithium (SLI) announced that director Karen Narwold will resign from its Board of Directors effective September 15, 2026, after accepting a new executive position with greater time commitments.
After her resignation, the Board will comprise eight directors. The company has started a search for a new independent director whose background is expected to complement the existing Board experience and support Standard Lithium’s growth and strategic objectives. An appointment will be announced once this process is complete.
Smackover Lithium (SLI) released a positive Preliminary Economic Assessment for the Franklin lithium brine project in East Texas, its first project in the region.
The PEA outlines an unlevered after-tax NPV8 of $4.99 billion, an after-tax IRR of 24% and a 3.1-year after-tax payback, based on a flat lithium carbonate price of $22,400/t over a 20-year modelled life. The project targets up to 70,000 tpa battery-quality lithium carbonate capacity, with average production of about 64,600 tpa, supported by average brine lithium concentration of 515 mg/L.
Initial lithium CAPEX is estimated at $3.5 billion (including 20% contingency), implying capital intensity of about $49,945/t. Average cash operating cost is projected at $4,226/t, with all-in costs of $5,054/t. The updated Mineral Resource includes 1.77 Mt LCE Indicated and 2.13 Mt LCE Inferred, plus sizeable bromide and potash resources that could provide additional future upside not included in the base case economics. Standard Lithium holds a 55% economic interest in the project.
Smackover Lithium (NYSE.A: SLI), the partnership between Standard Lithium and Equinor, signed a second binding take-or-pay offtake agreement for the South West Arkansas Project with LG Energy Solution. The Project will supply 8,000 metric tonnes per year of battery-quality lithium carbonate over 10 years after commercial start-up, with pricing structured to support project financing.
Combined with the previously announced 8,000 tpa Trafigura offtake, roughly 90% of the SWA Project’s targeted offtake volume (aiming for ~80% of 22,500 tpa nameplate capacity) is now committed. The offtake and financing processes are linked, with indications of interest for over $1 billion in project debt from three export credit agencies. The partnership targets a Final Investment Decision in 2026, construction shortly thereafter, and first commercial production in 2029.
Nano One (TSX:NANO, OTCQB:NNOMF) has produced LFP cathode active material and in-house battery test cells using battery-quality lithium carbonate supplied by Standard Lithium (TSXV:SLI, NYSE American:SLI) from its South West Arkansas pilot plant.
Using its patented One-Pot process, Nano One reports that the material met target chemical and physical parameters, achieved intended particle morphology and delivered initial electrochemical performance of approximately 155 mAh/g on first discharge. This work supports Nano One’s staged A-to-C sample qualification strategy and expands pre-qualified feedstock options for prospective licensees and customers. Nano One is also expanding capacity at its Candiac facility to about 800 tpa, with detailed engineering 85% complete as of July 2026 and commissioning of the expanded demonstration line targeted for the first half of 2027.
Standard Lithium (NYSE American: SLI) reported that lithium carbonate produced from its South West Arkansas (SWA) Project pilot plant was successfully used by Nano One to manufacture lithium iron phosphate (LFP) cathode active material and coin cells in North America.
According to Standard Lithium, approximately one kilogram of battery-quality lithium carbonate from its SWA brine and process flowsheet was processed via Nano One’s One-Pot method. The LFP material showed desired chemical and physical properties, appropriate particle morphology and delivered around 155 mAh/g on first discharge, providing further validation of the SWA flowsheet and the suitability of its lithium carbonate for downstream battery applications and domestic supply chain development.
Standard Lithium (TSXV/NYSE American: SLI) reported Q2 2026 results, highlighting major de-risking steps for the South West Arkansas (“SWA”) lithium project. The U.S. Department of Energy completed its NEPA review and issued a Finding of No Significant Impact (FONSI), satisfying a key requirement linked to the previously awarded $225 million DOE grant.
The company executed an EPCC contract with S&B Engineers and Constructors for the central processing facility and an EPCM contract with Wood Group for the upstream well field, both with Limited Notices to Proceed ahead of a Final Investment Decision (“FID”). At its Arkansas demonstration plant, Standard Lithium reached 1 million barrels of brine processed, over 15,000 DLE cycles and about 340,000 man hours with zero incidents. As of June 30, 2026, cash was $137.3 million with no term or revolving debt. The company continues to target FID later in 2026 and first commercial production in 2029.
Smackover Lithium (TSXV, NYSE.A: SLI), a partnership between Standard Lithium and Equinor, signed an EPCC agreement with S&B Engineers and Constructors for the Central Processing Facility of the South West Arkansas lithium project.
The CPF covers about two-thirds of estimated capex and is designed for 22,500 tpa battery-quality lithium carbonate. A Limited Notice to Proceed enables detailed engineering, permitting and early procurement ahead of a targeted 2026 Final Investment Decision.
Smackover Lithium (NYSE American:SLI), a partnership between Standard Lithium and Equinor, awarded an EPCM contract to Wood for the upstream well field of the South West Arkansas lithium project.
The project targets 22,500 tpa battery-quality lithium carbonate; FID is expected in 2026, with a Limited Notice to Proceed enabling early engineering, permitting and procurement.
Smackover Lithium (NYSE:SLI), the partnership between Standard Lithium and Equinor, received a Finding of No Significant Impact (FONSI) from the U.S. Department of Energy for its South West Arkansas Project under NEPA, with no additional mitigation required.
