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.”

About Standard Lithium Ltd.

Standard Lithium is a leading near-commercial lithium development company with a portfolio of projects in process. The

Company’s flagship projects, the Lanxess Project and the South West Arkansas Project, are located in Southern Arkansas

near the Louisiana state line. The Company is focused on the evaluation and testing of commercial lithium extraction and

purification from brine sourced from approximately 180,000 acres of unitized leases across these two projects. The Company

operates a first-of-a-kind industrial-scale Direct Lithium Extraction (DLE) Demonstration Plant at the Lanxess Project. The

scalable, environmentally friendly process eliminates the use of evaporation ponds, reduces processing time from months to

hours and greatly increases the effective recovery of lithium. A Definitive Feasibility Study (DFS) and Front-End Engineering

Study (FEED) for Phase 1A of the Lanxess Project commenced in September 2022. A Preliminary Feasibility Study (PFS) of

the South West Arkansas Project commenced in May 2022. The Company is also pursuing the resource development of other

projects in the Smackover Formation in East Texas, as well as approximately 45,000 acres of mineral leases located in the

Mojave Desert in San Bernardino County, California.
