The USGS did publish a major assessment in 2025 (Fact Sheet 2025-3022) estimating approximately 2.9 million metric tons of lithium resources in the Appalachian basin, which is roughly equivalent to about 300 years of U.S. lithium import requirements based on historical consumption rates. The statement's core claim about the Appalachian lithium assessment and its scale is factually accurate.

The USGS has not published a finding that the Appalachian region contains enough lithium to replace 328 years of U.S. imports; such a specific figure does not appear in any USGS assessment, and the claim exaggerates the scale of Appalachian lithium resources relative to known estimates.

There is no USGS report stating that the Appalachian region contains enough lithium to replace 328 years of imports; the claim appears to be a misrepresentation or exaggeration of USGS data.
