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.

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.

New research suggests that Arkansas may be home to upwards of 19 million tons of lithium reserves, which would give the United States an opportunity to lead in the electric vehicle industry. The United States Geological Survey unveiled the findings on Monday,

Shares of lithium producers surge as new research reveals massive lithium reserves in Arkansas, potentially meeting global demand for EV batteries.

A study conducted by the USGS estimates that Arkansas's Lithium reserves could be 9x more than the projected global Lithium demand for EVs in 2030.

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

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.
