Feasibility Study Updates on Flagship Arkansas Projects

The Company also announces progress updates on the feasibility studies related to the LANXESS Project (“LANXESS”) and South West Arkansas Project (“SWA”).

“We expect to file the feasibility studies for our flagship Arkansas projects early in the third quarter,” said Dr. Andy Robinson, COO and Director of Standard Lithium. “Our project teams and partners are working diligently to complete the studies, which we are eager to finalize and share with key stakeholders. We look forward to showcasing the hard work our teams have put in over the last 12 months.”

In September 2022, the Company commenced a Definitive Feasibility Study (“DFS”) and Front-End Engineering Study for Phase 1A of the LANXESS Project (see news release dated 7 September 2022). The South West Arkansas Preliminary Feasibility Study (“PFS”) began in May 2022 (see news release dated 2 May 2022); both the DFS and PFS are expected to be complete in early third quarter 2023.

Dr. Robinson shared: “We await final vendor pricing for our LANXESS Project DFS and for critical, third-party analytical data from the SWA drilling work for the PFS. We have analysed all of the brine samples from SWA at our own analytical facility and anticipate sharing the data once we receive verification from the external laboratory. We continue to expect our flagship Arkansas projects to be meaningful contributors to U.S. lithium production in the coming decades.”
