THE WOODLANDS, Texas, Sept. 21, 2022 /PRNewswire/ -- TETRA Technologies, Inc. ("TETRA" or the "Company") (NYSE: TTI) announced the completion of its maiden inferred bromine and lithium brine resource estimation report for its brine minerals leased acreage in the Smackover Formation in Southwest Arkansas. The technical report summary, which is available in its entirety on TETRA's website Investor Relations - Presentations (tetratec.com), reflects the following.

TETRA has identified a direct lithium extraction (DLE) technology based on adsorption/desorption using a proven, commercially available resin that is currently being successfully used in commercial lithium extraction operations from salar brines. Using our lithium-rich Arkansas brine samples from our recently completed test well, our inferred resource report details the excellent DLE laboratory and pilot unit results from our research group at our TETRA Innovation Group Technology Center in Conroe, Texas.

"The inferred resource report also confirms that the Smackover Formation is enriched in bromine (an average of 5,371 mg/liter) and lithium (an average of 416 mg/liter), which we expected based on our previously disclosed test well fluid sampling results. Based on the recent test well drilled on the TETRA 5,000 acres, the brine samples from the Upper Smackover Member within that well yielded the highest recorded lithium values (461-489 mg/liter) within the Upper Smackover Member, which may indicate uniquely elevated lithium brine within the targeted acreage where TETRA retains both the bromine and lithium rights.
