Westwater Resources Announces Issuance of U.S. Patent for Graphite Purification Technology at Kellyton Graphite Plant

Westwater Resources, Inc. (NYSE American: WWR) an energy technology and critical minerals company, focused on developing battery-grade natural graphite (“Westwater,” “Westwater Resources,” or the “Company”), has received U.S. Patent Number 12,415,731 for innovative graphite purification methods. This patent, awarded by the U.S. Patent and Trademark Office, is a significant milestone in Westwater’s technological advancement and reinforces the Company’s dedication to sustainable, domestic graphite production.

“We’re proud to reach this milestone after five years of the patenting process with the U.S. Patent and Trademark Office,” said Terence Cryan, Executive Chairman and Chairman of the Board of Westwater Resources. “This patent protects our environmentally-friendly purification technology and underscores Westwater’s leadership as the most advanced, U.S.-based producer of battery-grade natural graphite. We are dedicated to helping supply the critical minerals that the U.S. needs to support energy independence.”

In August 2020, Westwater Resources filed its first patent application for the proprietary method of graphite purification to be employed at the Kellyton Graphite Processing Plant. This innovative process offers a more sustainable alternative to traditional purification techniques often used in China and other countries. Unlike conventional methods that frequently rely on hydrofluoric acid, Kellyton’s Phase 1 process completely avoids the use of this hazardous substance. Instead, Westwater’s patented process relies on a more environmentally-friendly approach to produce high-purity graphite, positioning the Company as a leader in sustainable production of battery-grade natural graphite.
