RESTON, Va. — The Appalachian region of the eastern United States contains an estimated 2.3 million metric tons of undiscovered, economically recoverable lithium, enough to replace 328 years of U.S. imports at last year’s level, according to new research by the U.S. Geological Survey. The southern Appalachians hold an estimated 1.43 million metric tons of lithium oxide, concentrated in the Carolinas, and the northern Appalachians hold an estimated 900,000 metric tons, concentrated in Maine and New Hampshire, according to estimates in a new USGS scientific paper published in Natural Resources Research. The lithium is present in pegmatites, large-grained rocks similar to granite. “This research shows that the Appalachians contain enough lithium to help meet the nation’s growing needs – a major contribution to U.S.

mineral security, at a time when global lithium demand is rising rapidly,” said USGS Director Ned Mamula. “USGS mineral science is the leading edge in the effort to restore America’s mineral independence by mapping our nation’s mineral resources. Everything else follows on the science: permitting reform and other policy changes to support investment in clean, responsible mining to 21st century standards, and mining workforce training for new American jobs. The United States was the dominant world producer of lithium three decades ago, and this research highlights the abundant potential to reclaim our mineral independence.” The United
