This certainly seems like good news:

The USGS is saying that Appalachia 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. …

As lithium demand is projected to grow more than 48-fold by 2040, driven by electric vehicles and energy storage technologies, securing new domestic sources has become increasingly critical.

USDS Director Ned Mamula notes that the US was the dominant world producer of lithium three decades ago. The newly published lithium resource estimates are preliminary, and much more work is needed to fully realize our current mineral capacity.
