Key metrics: 22,500 tpa battery‑quality lithium carbonate capacity; 20‑year modeled life; 447,000 tonnes LCE proven reserves (38% of 1,177,000 t Measured & Indicated); average starting brine concentration 549 mg/L; processed brine volume 0.50 km3.

Economics: 20.2% unlevered pre‑tax IRR; average cash operating cost $4,516/t; all‑in cost $5,924/t; Class III capex estimate $1.45B (12.3% risked contingency). Schedule: 34 months construction, FID recommendation, construction expected 2026, first production targeted 2028.

Smackover Lithium (NYSE.A: SLI), a joint venture between Standard Lithium and Equinor, has announced a significant maiden inferred resource for its Franklin Project in East Texas. The project revealed 2.2M tonnes of Lithium Carbonate Equivalent (LCE) with the highest reported lithium-in-brine grades in North America at 668 mg/L.

The resource assessment also identified 15.4M tonnes of potash and 2.6M tonnes of bromide within 0.61 km³ of brine volume. The project spans approximately 80,000 acres, with over 46,000 acres already leased. The highest concentration of 806 mg/L lithium was measured from the Pine Forest 1 well.

This development marks a crucial step toward the JV's goal of achieving 100,000 tonnes annual lithium chemicals production in Texas through multiple phases, supported by two additional planned projects that triple the portfolio area in the state.

TETRA Technologies (NYSE:TTI) announced significant upgrades to its Arkansas bromine project resources in an updated Definitive Feasibility Study. The company reported a 173% increase in Measured and Indicated bromine resources to 431 ktons in the Evergreen Unit, while maintaining proven and probable bromine reserves at 744 ktons.

Key highlights include a 163% increase in lithium resources to 585 ktons of lithium carbonate equivalent (LCE) and the identification of new critical minerals: 2.18 million tons of magnesium and 47,000 tons of manganese resources.
