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.

Operations at a quartz mine in western North Carolina have been shut down for more than five days after Hurricane Helene dumped 2 feet of rain on the town of Spruce Pine, washing out roads and cutting power to an area with an industry critical to semiconductor manufacturing across the world.

Those mines are now closed indefinitely, after Hurricane Helene dumped 2 feet of water on Spruce Pine, devastating the area. And with this singular supply of ultra-pure quartz cut off for the foreseeable future, the world’s supply of chips hangs in the balance.
