Standard Lithium Corporate Update

VANCOUVER, British Columbia, July 13, 2022 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. ("Standard Lithium” or the "Company”) (TSXV: SLI) (NYSE American: SLI) (FRA: S5L), an innovative technology and lithium project development company, provides an update on several corporate and project developments.

Key Highlights:

• Key management additions to drive project execution
• Master Service Agreement with Telescope Innovations to perform CO₂ sequestration R&D
• DFS/FEED Study Award
• Senior management increase shareholdings

The Company recently added key personnel to the executive and management team in newly created positions to expand project delivery expertise in support of its commercial scale developments. Jason Tielker P.Eng. has taken on the role of Vice President Project Delivery, and Angus Remfry CEng has commenced as Director Project Delivery. Mr. Tielker’s initial focus is delivering Standard Lithium’s first plant to commercial operation, currently being planned for the Lanxess South Facility. Mr. Remfry’s primary responsibility is developing the South West Arkansas Project to the PFS stage, and drive several current project development initiatives. Collectively Mr. Tielker and Mr. Remfry have decades of experience managing large energy, mining and infrastructure projects through design and construction in North America and other parts of the world.

The Company is currently reviewing Pre-FEED deliverables related to the first commercial plant (see news release from January 2022) with a goal to awarding the FEED and Definitive Feasibility Study work no later than August.

As part of the Company’s continued focus on reducing carbon intensity (see news releases from September 2021, and May 2022), it has signed a Master Service Agreement ("MSA”) with Telescope Innovations Corp. ("TELI”) to conduct novel CO₂-focussed R&D. TELI is an innovative chemical technology company headed by Professor Jason Hein. Professor Hein has worked successfully with Standard Lithium previously and is the inventor of the Company’s proprietary SiFT lithium carbonate crystallization technology. TELI is working initially on understanding how CO₂ may be permanently sequestered by the Company as part of normal brine reinjection activities. This R&D program will then expand to consider how CO₂ may also be used as an alternative reagent at several points in the Company’s process flowsheet.

Dr. Andy Robinson, President and COO of Standard Lithium commented, "Standard Lithium and our contractors have been working diligently through the Pre-FEED process to refine designs and work towards the award of the FEED and DFS contract. We have been adding several key internal resources and are delighted to have Jason and Angus on board to help us accelerate all our projects; they bring invaluable big-project delivery expertise that will be needed as we move towards construction on our first commercial project and continue to advance our pipeline of development projects. As we contemplate the ever more significant role of CO₂ in the future economy, our engagement with Telescope Innovations is very timely. We have the potential to actively decarbonize our business and sequester significant quantities of CO₂ deep underground as part of our future lithium extraction and brine recycling operations, and as such, a thorough understanding of the chemistry and technology required is paramount. Standard Lithium has previously benefitted from Professor Hein’s expertise and is delighted to work with him and Telescope’s world-class team to better understand this potential future value creation stream.”

The Company also announces that Robert Mintak, Chief Executive Officer of the Company, Dr. Andy Robinson, President of the Company, and Kara Norman, Chief Financial Officer of the Company, have exercised a total of 1,400,000 incentive stock options (the "Options”) previously scheduled to expire on June 16, 2022. The Company has received proceeds of $1,344,000 from the exercise of the Options. To partially fund the option exercise and withholding tax obligations, Mr. Mintak, Mr. Robinson, and Ms. Norman, disposed of a total of 449,545 common shares from their existing holdings, and may in the future dispose of additional shares in order to satisfy tax obligations associated with the Options. As a result of the exercise of the options, and the subsequent dispositions, Mr. Mintak, Mr. Robinson and Ms. Norman have increased their overall ownership interest in the Company by 950,455 common shares.

About Standard Lithium Ltd.
Standard Lithium is an innovative technology and lithium development company. The Company’s flagship project is located in southern Arkansas, where it is engaged in the testing and proving of the commercial viability of lithium extraction from over 150,000 acres of permitted brine operations. The Company operates its first-of-a-kind industrial-scale Direct Lithium Extraction (DLE) demonstration plant at Lanxess’s south plant facility in southern Arkansas. The demonstration plant utilizes the Company’s proprietary LiSTR technology to selectively extract lithium from Lanxess’s tail brine. The demonstration plant is being used for proof-of-concept and commercial feasibility studies. 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. The Company is also pursuing the resource development of over 30,000 acres of separate brine leases located in southwest Arkansas, referred to as the South West Arkansas Lithium Project, and approximately 45,000 acres of mineral leases located in the Mojave Desert in San Bernardino County, California.

Standard Lithium is jointly listed on the TSX Venture Exchange and the NYSE American under the trading symbol "SLI”; and on the Frankfurt Stock Exchange under the symbol "S5L”. Please visit the Company’s website at https://www.standardlithium.com.
