What Happened
Weeks after the announcement that discovery of a significant lithium deposit in Arkansas was made, the U.S. Bureau of Land Management (BLM) gave final permit approval for a lithium/boron mine in Nevada as part of a strategy to boost domestic supplies of the metal, which is crucial to production of rechargeable batteries.
Significance/Outlook
Chile and Argentina supply the U.S. with over 90 percent of its raw lithium supply, which is processed largely by facilities in Canada. The new Nevada mine is scheduled to come fully online in 2028 to become only the third U.S. source for mined lithium. It will have its own processing facilities and could produce enough lithium to support the production of about a third of a million electric vehicles a year, the BLM reported. Meanwhile, the U.S. Geological Survey (USGS) announced the discovery of an estimated 5 million to 13 million tons of lithium dissolved in underground brine reservoirs in Arkansas. The material was found in the Smackover Formation, a geological feature that stretches from Texas to Florida. Companies there are studying ways to extract that lithium directly from the water, a process less prone to contamination of fresh groundwater than evaporative methods commonly used in South America.
