Standard Lithium Commissions Hunt Guillot & Associates LLC for Engineering Services for Arkansas Pilot Plant

VANCOUVER, British Columbia, June 14, 2018 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. ("Standard Lithium" or the "Company") (TSX-V:SLL) (FRA:S5L) is pleased to announce that they have engaged Hunt Guillot & Associates LLC (HGA) of Ruston, Louisiana, to provide engineering services for site preparation, utility connections and brine supply/disposal pipeline connections at the Company's Pilot Plant site location in El Dorado, Southern Arkansas.  HGA experts are very familiar with the plant location, and their scope of work includes geotechnical investigations and civil infrastructure required to site the pilot plant modules; design and tendering of any structures required to house and protect the pilot plant infrastructure; all utility and brine pipeline interconnections; and pilot plant installation.

Dr. Andy Robinson, COO and President of Standard Lithium commented, "Our engagement of HGA is another key step accomplished in our goal to installing our full-scale, continuous Pilot Plant.  The location that has been selected for installation is ideal; utility and brine pipeline connections are immediately adjacent, and we expect that with HGA's extensive experience in the region, installation of the pilot plant will be a relatively straightforward process.  Our process engineering team is now full-swing in the design phase for the pilot and we look forward to observing the build-out of all the pilot plant modules over the second half of 2018."

Robert Mintak, CEO of Standard Lithium commented, "With the engagement of HGA to provide site engineering services, we demonstrate the continued execution of our development strategy.  There are many companies pursuing and proposing extraction technologies and process developments to unlock lithium resources.  We stand apart from the crowd, and have secured brine projects with permitted, producing operators, have signed contracts to build and install our demonstration plant in Southern Arkansas, and we are well funded to meet our development timelines."
