<b xmlns="http://www.w3.org/1999/xhtml">Westwater Resources, Inc. (NYSE:<a class="ticker" href="https://www.benzinga.com/quote/WWR">WWR</a>)</b>, an energy technology and battery-grade natural graphite company ("Westwater" or the "Company"), today announced that it has submitted a Section 404 permit application to the U.S. Army Corps of Engineers for the Company's Coosa Graphite Deposit in Coosa County, Alabama.

</p><p xmlns="http://www.w3.org/1999/xhtml">
The Section 404 permit application, submitted under the Clean Water Act, represents an important step in the permitting process for Coosa. The application relates to certain potential impacts to water associated with future development activities at the project site.

</p><p xmlns="http://www.w3.org/1999/xhtml">
"Submission of the Section 404 permit application reflects continued progress in advancing Coosa through the permitting process," said Frank Bakker, President and Chief Executive Officer of Westwater Resources. "Coosa is intended to serve as a future domestic feedstock source for our Kellyton Graphite Plant, supporting our objective of developing a secure U.S. vertically-integrated supply of battery-grade graphite."

</p><p xmlns="http://www.w3.org/1999/xhtml">
The Section 404 application follows the Company's previously announced permit application filed earlier this year with the Alabama Department of Environmental Management ("ADEM"). Together, these permitting steps support Westwater's continued advancement of Coosa through environmental review and permitting.

Westwater expects to continue advancing Coosa in alignment with the FAST-41 process and currently anticipates evaluating a final investment decision for the Coosa project following completion of the broader permitting process.

</p><p xmlns="http://www.w3.org/1999/xhtml">
The Coosa Graphite Deposit is located approximately 30 miles from Westwater's Kellyton Graphite Plant in east-central Alabama. Coosa is the largest and most developed graphite deposit in the contiguous United States and will provide a long-term domestic source of natural flake graphite feedstock, while Kellyton is being developed to process natural flake graphite into battery-grade graphite. Together, these assets support Westwater's vertically-integrated, mine-to-market strategy of developing U.S.-based graphite production capacity for domestic battery supply chains.
