Westwater Resources, Inc. (NYSE American: WWR), an energy technology and battery-grade natural graphite company (“Westwater” or the “Company”), today announced continued progress related to the Coosa Graphite Mine (“Coosa”) in Coosa County, Alabama.

Coosa is advancing as a covered project under FAST-41, which provides a coordinated and transparent framework for federal environmental review and permitting. Westwater continues to work with participating agencies in accordance with the project timetable published on the federal Permitting Dashboard, which currently targets completion of the permitting process for Coosa in June 2027.

“We are making steady progress across the permitting workstreams required to advance Coosa responsibly,” said Frank Bakker, President and Chief Executive Officer of Westwater Resources. “The completion of the Endangered Species Act consultation ahead of schedule, advancement of the Section 404 permit beyond public comment and completion of important environmental fieldwork reflect the work underway. Coosa remains an important component of our mine-to-market strategy and is intended to provide a secure, long-term domestic source of natural graphite feedstock for our Kellyton Graphite Plant.”

Federal Permitting

  • Section 404 permit: Westwater submitted its Clean Water Act Section 404 individual permit application to the U.S. Army Corps of Engineers (“USACE”) in June 2026. The public-comment period has concluded, and USACE is reviewing the comments received as the application advances through the next phase of review.
  • Endangered Species Act consultation: The consultation concluded ahead of the FAST-41 timetable following comprehensive environmental fieldwork, habitat assessments and coordination with the relevant agencies.
  • Cultural resources: Cultural-resource fieldwork is complete for the proposed project footprint, including additional acreage associated with the planned tailings-disposal area. No sites were identified as potentially eligible for inclusion on the National Register of Historic Places, and the survey results have been submitted to USACE.
  • Wetlands and streams: Wetland-delineation and stream-assessment fieldwork and reporting are complete. Westwater recently submitted the supporting materials requested by USACE to determine which wetlands and streams fall under federal jurisdiction, an important step in defining the scope of the Section 404 permit review.

State Permitting

  • NPDES permit: Westwater submitted its application for a National Pollutant Discharge Elimination System (“NPDES”) permit to the Alabama Department of Environmental Management (“ADEM”) during the first quarter of 2026. Technical review is underway, including the submission and evaluation of site-specific information regarding the proposed mining and processing methods, water-treatment technologies and discharge controls.
  • Water-quality certification: The Company submitted its application for the state water-quality certification associated with the Section 404 permit to ADEM in June 2026. The application has been accepted and is progressing through the state review process.

Westwater will continue advancing Coosa in alignment with the FAST-41 timetable while working closely with USACE, ADEM, the U.S. Fish and Wildlife Service and other federal, state and local stakeholders. As the permitting process progresses, Westwater is also advancing the technical work needed to support future mine planning and design at Coosa.

Preliminary Mine Planning and Design Underway at Coosa

Westwater has initiated studies to advance preliminary mine planning and design for the Coosa Graphite Mine. These studies will evaluate the potential value of the vanadium mineralization at Coosa and its inclusion in the mine plan.
