STANDARD LITHIUM LTD. (SLI) Form 6-K — Oct 20, 2026
Standard Lithium filed an NI 43-101 Preliminary Economic Assessment for its Franklin Project in Hopkins, Franklin, and Titus Counties, Texas, outlining a 20-year direct lithium extraction operation. The base case shows an after-tax NPV8 of $4,992 million, a 24% IRR, and a 3.1-year payback, with an upgraded bromine co-product case lifting after-tax NPV8 to $5,560 million. The project holds an estimated 2,128 kt of contained lithium carbonate equivalent (400 kt lithium) in the Smackover Formation, with plans to produce roughly 1,292 kt of LCE over the project life at a $22,400/t lithium price and 89.25% process recovery. Total capital cost is estimated at $3.83 billion.
