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.

New research suggests Arkansas may be home to up to 19 million tons of lithium reserves, potentially giving the U.S. the chance to lead in the EV industry.

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.

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.

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

A study completed by the USGS found that there are lithium reserves located under southwestern Arkansas that's estimated to between 5 and 19 million tons.

Researchers now estimate how much “white gold” may be found in southern Arkansas's vast lithium reserves: up to 19 million tons, or enough to meet the projected 2030 world demand nine times over.
