Lithium content in South Arkansas brine pleases standard lithium

SMM8, 30 March: standard Lithium Co., Ltd. said Tuesday that its laboratory results show that the company's project area in southwestern Arkansas has recovered high-quality lithium salt from the Smackover formation.

Four brine samples recovered from two existing wells in the project area showed that the lithium concentration was between 347 and 461 mg / L, with an average lithium content of 450 mg / L in one well and 350 mg / L in the other well.

Dr. Andy Robinson, President and Chief operating Officer of Standard Lithium, said: "the latest brine data from the Smackover group is an excellent testament to the quality of lithium salt water available to the company in its southwestern Arkansas project. We have now completed all the geological modeling of our project areas in Lafayette and Columbia County, and with these recent geochemical data, we are making final changes to our first resource report. It is also hoped that this important resource will be released in the near future. "

Salt water is collected from pre-existing oil and gas wells previously drilled into the Smackover formation and completed at a depth of about 9300 feet. Some historical infrastructure (production pipes, Packers, etc.) was removed from the two holes and new production pipes were installed in the wells to allow sampling. In addition to this minimal work, it was found that these wells were in good condition, pierced in the correct saline production area ("Reynolds units" in the Smackover group) and produced large amounts of salt water from the formation using the following methods. Available workover rig. All work is done by and in cooperation with the oil and gas operators responsible for the wells.

Salt water samples were sent to the WETLAB Test Laboratory in Sparks, Nevada for total saline analysis.

Robert Mintak, CEO of Standard Lithium, said: "recent sampling results confirm our development strategy of using large amounts of data and existing infrastructure to acquire assets. Because we can complete this work plan to the company and shareholders at the lowest cost. With our major agreements and partnerships, first resource reporting and demonstration plants, we believe that the company's project in southern Arkansas will play a leading role in the next wave of lithium producers. "

The Canadian company uses the company's proprietary selective extraction technology to test and demonstrate the commercial feasibility of lithium extraction from more than 150000 acres of licensed brine operations in South Arkansas. The company is also looking for more than 30000 acres of separately leased salt water resources in southwestern Arkansas.

In June, the company said it had commissioned Saltworks Technologies Inc. A selective crystallization plant was designed and built to continuously produce battery-grade lithium carbonate at El Dorado.

Crystallization equipment will be automated and machine learning will be used to optimize crystallization conditions. The selective crystallization plant will be designed, built and tested in Vancouver and will then be deployed at the company's pilot plant in Union County.
