Quantitative Mineral Resource Assessment of Lithium Pegmatite Deposits in the Northern Appalachian Orogen, USA | Natural Resources Research | Springer Nature Link
A April 2026 U.S. Geological Survey (USGS) report identified that New Hampshire, along with Maine and the Connecticut, is part of an Appalachian region holding an estimated 2.3 million metric tons of undiscovered lithium. This Appalachian lithium cache could support 130 million electric vehicles and significantly reduce U.S. reliance on imported, critical minerals.
