Grounded Lithium Provides Update on Direct Lithium Extraction Selection Process and Further Lithium Concentration Testing

CALGARY, AB, May 9, 2023 /PRNewswire/ – (TSXV: GRD) (OTCQB: GRDAF) – Grounded Lithium Corp. (“GLC” or the “Company”) is pleased to provide an update on our direct lithium extraction (“DLE“) selection process. As previously communicated in news releases dated March 13, 2023 and March 21, 2023, we selected our top two technology firms, which were deemed the most applicable for our specific brine chemistry, to test Kindersley Lithium Project brine (“KLP Brine“). Large volumes of KLP Brine were shipped earlier in the month to both labs and extraction testing commenced in parallel. As part of the initial gating process both labs independently tested the KLP Brine for qualities and impurities to provide a baseline assessment and characterization. In both cases, concentrations met or exceeded the concentrations previously communicated by the Company of 74-81 mg/l of lithium, providing support to conduct fulsome extraction technology testing which is now nearing completion. Measured lithium concentrations for characterization purposes averaged 80 mg/l. Samples provided to both DLE labs were sourced from the Company’s first initial lithium test well at 4-15-32-23W3 (the “4-15 Well“), specifically brine was collected throughout the open hole section from 966m to 1145m. Grounded produced sufficient quantities of brine from the 4-15 Well during production testing in November 2022 and securely stored those samples at a facility in the Kindersley area. Our handling process maintained strict custody of control during transportation to the respective labs. Once received, these independent labs used industry accepted practices and equipment to determine brine chemistry, specifically testing for concentrations of lithium.
