Vancouver-based Standard Lithium, reported on Tuesday it has recovered high-quality lithium brines from the Smackover Formation from its project area in southwestern Arkansas.
The company extracted four brine samples from two existing wells in the project area. Laboratory testing showed lithium concentrations ranging between 347-461 mg/L lithium. One of the wells averaged 450 mg/L lithium and the other averaged 350 mg/L.
Dr. Andy Robinson, President and COO of Standard Lithium commented, “the latest brine data from the Smackover Formation are an excellent demonstration of the quality of lithium brine.”
He added “we are now at the point where we’ve completed all geological modelling of our project area in Lafayette and Columbia counties, and with these recent geochemical data, we are putting the finishing touches to our maiden resource report and hope to be able to release the report describing this important resource in the near future.”
According to the company, the brines were sampled from pre-existing oil and gas wells that had been drilled into the Smackover Formation, and were completed at depths of about 9,300 feet below ground level.
The company says some production tubing, packers and other historical infrastructure had to be removed from the two holes and new production tubing was installed in the wells for sampling.
“Other than this minimal work, the wells were found to be in good condition, were perforated in the correct zone for brine production, and produced large volumes of brine from the formation using a readily-available workover rig,” said the company in a press release.
All the work was completed by, and in partnership with, the oil and gas operator responsible for the wells. Brine samples were then sent to WETLAB Testing Laboratory in Sparks Nevada for full brine analysis.
Robert Mintak, CEO of Standard Lithium said “The recent sampling results confirm our development strategy of acquiring assets with substantial data and existing infrastructure, as we were able to complete this work program at minimal cost to the company and shareholders”.
He added “we believe the company’s southern Arkansas projects are set to play a leading role in the next wave of lithium producers.”
Along with the Smackover Formation project, Standard Lithium is pursuing the resource development of over 30,000 acres of separate brine leases located in southwestern Arkansas and about 45,000 acres of mineral leases located in the Mojave Desert in San Bernardino County, California.
