The owner of a North Carolina quartz mine that’s a key source for high-purity quartz used in global semiconductor manufacturing said its operations sustained only minor damage in the wake of Hurricane Helene.

Two facilities that produce high-purity quartz essential in semiconductors, solar panels, and fiber-optics have been shut down.

Closures from storm damage could lead to supply-chain bottlenecks — and price increases — for the chips used in smartphones, computers and cars.
