USGS Confirms 2.5 Million Tons of Lithium in Appalachian Mountains
The Appalachian Mountains contain an estimated 2.5 million tons of lithium, sufficient for 500 billion smartphones and 130 million electric vehicles. This discovery is crucial as global demand for battery materials escalates, highlighting the region's potential to bolster domestic lithium supplies.

The US Geological Survey (USGS) reports that the Appalachian Mountains hold approximately 2.5 million tons of lithium, enough to cover US lithium imports for about 328 years at last year's levels. This resource, locked in pegmatite formations, is distributed with an estimated 990,000 tons in the northern region and 1.57 million tons in the south, particularly in states such as North Carolina and South Carolina, which historically contributed to US lithium production.
While the findings indicate substantial resources, the extraction process poses significant environmental risks and challenges, requiring careful management to avoid habitat disruption and soil contamination. Moreover, the limited current domestic production, with only one active lithium mine in Nevada, underscores the potential impact of developing these resources on US energy security and supply chains.
