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.

Arkansas is sitting atop lithium reserves that could be vast enough to satisfy the entire world’s demand for EV batteries, according to the US Geological Survey (USGS).

Federal and state researchers said there might be five million to 19 million tons of lithium, more than enough to meet the world’s demand for the battery ingredient.

Researchers say the Smackover Formation could hold enough lithium to supply global demand for years to come — if it can be commercially recovered.

A new study by the U.S. Geological Survey found massive lithium reserves in southwestern Arkansas that could have between 5 million and 19 million tons of lithium.

A U.S. Geological Survey (USGS)-led study has revealed an enormous lithium deposit in southwestern Arkansas that could potentially revolutionize the global electric vehicle industry. Using innovative water testing methods combined with machine learning,
