The discovery could supply 300 years of US lithium imports but faces decade-long permitting and production delays.
The US Geological Survey identified 2.3 million metric tons of lithium in the Appalachian region, primarily in the Carolinas. This volume could replace over 300 years of current US lithium imports or power 130 million electric vehicles, according to estimates.
However, the gap between discovery and production remains significant. US permitting for hardrock pegmatite mining typically spans seven to 10 years, followed by another three to five years to build processing infrastructure. Historically, such projects face 10-20 year timelines before commercial output.
Retail investors may misinterpret the announcement as an immediate opportunity. Companies often fund development through dilutive equity raises, with share-count increases of 50% or more over a decade not uncommon. Only one US company currently produces lithium domestically.
