The US Geological Survey (USGS) released findings on Monday (October 21) indicating that Southwestern Arkansas may contain substantial lithium reserves, estimated between 5 million and 19 million metric tons.

A study released this week by the USGS finds the Smackover formation in Southern Arkansas may contain 9 times the estimated global demand for lithium through 2030.

Suspended in the relic of an ancient sea beneath southern Arkansas, there may be enough lithium for nine times the expected global demand for the element in car batteries in 2030. A collaborative national and state government research team trained a machine learning model to predict and map the lithium concentrations of salty water deep within the porous limestone aquifer beneath southern Arkansas,

A new USGS survey, made possible through machine learning and environmental testing, has led to the discovery of an estimated 5 to 19 million tons of lithium reserves under southwestern Arkansas. It's an amount that,

The lithium mine, calculated using a machine-learning model and geological information that predicted maps of lithium concentration, represents 35% to 136% of the current amount of lithium estimated to be in the U.S. Lithium could be extracted from the waste stream of the brines—deposits of groundwater rich in minerals—in the Smackover Formation.
