WCCB Charlotte's CW July 19, 2021 GASTON CO., N.C. – Tuesday night, neighbors hope to learn more about plans for a proposed lithium mine in Gaston County. The material would be used to power batteries for electric cars, but neighbors worry about the environmental impact. Piedmont Lithium wants to build the mine on a site off Highway 150, east of Cherryville. Company officials will make a presentation to Gaston County Commissioners on Tuesday night. The company claims the site will be one of the world’s largest and lowest-cost produces of lithium hydroxide, and would be more sustainable than other lithium mines in China and South America.
