Standard Lithium Ltd. (TSXV: SLI), a leading near-commercial lithium company, has announced that as part of some resource definition work at its southwest Arkansas project, it has sampled the highest confirmed lithium grade brine in Arkansas, with a grade of 581mg/L. These sampling data follow similar high-grade results from the company’s resources in Texas.
Dr. Andy Robinson, president and COO of Standard Lithium commented, “We continue to be very pleasantly surprised by the lithium grades sampled from our projects in Arkansas and Texas.”
The company’s LANXESS and southwest Arkansas flagship projects, in southern Arkansas near the Louisiana state line.
Standard is focused on the evaluation and testing of commercial lithium extraction and purification from brine, sourced from approximately 180,000 acres of leases across these two projects.
The lithium brine samples were taken from a pre-existing, well located in the central-eastern part of the company’s project area. This well (the Beulah-Taylor#1) was first drilled in July 1982 and subsequently decommissioned in August 1982.
Standard Lithium commenced drilling on 21 February 2023 and deepened the hole to a measured depth of 8,940ft.
All brine samples were analysed at multiple analytical laboratories to confirm sample quality and maintain QA/QC procedures.
“This recent infill drilling work to further define the lithium resource has resulted in a marked upside to the in-situ lithium grade. In our experience, the grade of lithium in brine used for direct lithium extraction (DLE) has a meaningful impact on both capital expenditures and operating costs in connection with the extraction process, so a higher- grade typically results in lower overall costs and should have a positive effect on project economics in the forthcoming preliminary feasibility study (PFS),”
“We are delighted that sampling from this recent well has led us to find lithium brine with the highest confirmed grade in Arkansas, and we look forward to incorporating these into the forthcoming PFS.”
