HAGENS BERMAN, NATIONAL TRIAL ATTORNEYS, Encourages Standard Lithium Ltd. (SLI) Investors to Contact Firm's Attorneys, Firm Investigating Possible Securities Law Violations

4:31 pm ET November 29, 2021 (Globe Newswire) Print

Standard Lithium Ltd. (SLI) Investigation:

The investigation focuses on Standard Lithium's claims that its proprietary LiSTR technology has achieved proof of concept ("POC") demonstrating its feasibility for extracting and processing lithium within hours instead of months and claims it will do so on a commercial scale at a plant built on the LANXESS AG bromine facility located in the southwestern region of Arkansas.

Standard Lithium's statements were brought into question on Nov. 18, 2021, when analyst Blue Orca published a scathing report based, in part, on production records filed by the company with the Arkansas Oil & Gas Commission.

According to the report, Standard Lithium's repeated claims that its technology will achieve 90% lithium recovery rates at the project are contradicted by data submitted to the Arkansas regulator indicating an average lithium recovery rate of just 13%.

Blue Orca also observed that, during LANXESS' Aug. 11, 2021 earnings call, its CEO (Matthias Zachert) directly contradicted Standard Lithium's Dec. 3, 2020 claim that its technology achieved POC.

This news sent the price of Standard Lithium shares sharply lower.

"We're focused on investors' losses and whether Standard Lithium lied about the viability of its technology and proposed project," said Reed Kathrein, the Hagens Berman partner leading the investigation.
