The Appalachian Mountains are starting to look less like a scenic backdrop and more like the front end of America’s battery supply chain. Federal researchers say the region holds a massive, previously underappreciated cache of lithium, and Albemarle’s long-idled Kings Mountain site in Cleveland County has now cleared key federal reviews, nudging the local mine from the planning boards toward a possible restart.
How Big Is the Find?
The U.S. Geological Survey estimates the Appalachian region contains about 2.3 million metric tons of economically recoverable lithium oxide, with roughly 1.43 million tons concentrated in the southern Appalachians, largely in the Carolinas, and about 900,000 tons in the northern Appalachians. At recent U.S. consumption levels, that amount could replace lithium imports for hundreds of years and mark a major step toward domestic mineral security, according to the U.S. Geological Survey.
What’s at Kings Mountain?
The Kings Mountain site is one of the better-known hard-rock lithium districts in the United States, and Albemarle’s public project plan calls for open-pit mining that would process roughly 3.1 million tons of ore a year to yield about 420,000 tons of spodumene concentrate for off-site conversion. Albemarle’s project materials show the operation would sit on an industrial footprint bisected by I-85 and within an existing, previously mined complex near the town of Kings Mountain, a short drive from Charlotte. Albemarle details the mine layout and long-range plan for the site.
Permits, Federal Backing and the Economics
Federal permitting under the FAST-41 process was completed for the Kings Mountain material processing project this spring, removing a major administrative obstacle to restarting surface mining operations. The Department of Energy’s review produced a Finding of No Significant Impact that clears the way for federal cost-share grants tied to the project, and the Department of Defense previously placed a $90 million agreement in support of expanding domestic lithium capacity at Kings Mountain. The DOE environmental assessment also estimates roughly 1,000 construction jobs and about 400 operational positions tied to the project and documents NPDES-authorized pit dewatering and a multi-year water-treatment plan to manage site discharges.

Community Concerns and Environmental Checks
Local reaction has been mixed. Supporters are focused on jobs and domestic supply-chain gains, while neighbors and environmental advocates have pressed regulators for tight safeguards on water, wetlands and wildlife. Local reporting and public comment records highlight scrutiny of water treatment, potential impacts to streams and wetlands, and long-term monitoring requirements as the project moves through state and federal reviews.

What Happens Next
With the federal steps in place, Albemarle still needs state and local permits and community agreements before any large-scale mining can begin. The company has said it plans to seek initial permitting for a defined operating window and to phase construction and processing over multiple years. The USGS assessment and the federal reviews together put Kings Mountain at the center of efforts to onshore more of the battery supply chain, but how fast things move will depend on remaining approvals, market conditions and how the company and regulators handle the environmental safeguards laid out in the DOE assessment.
