SnapshotThe Coosa graphite deposit and Kellyton graphite processing plant (currently under construction) together will represent the first fully integrated domestic battery-grade graphite project in the U.S.

During the third quarter of 2023, Westwater continued preparing the preliminary economic assessment (“PEA”) for the Coosa Graphite Deposit. Westwater expects to complete and disclose the results of the PEA in the fourth quarter of 2023.

Upon completion of the PEA, Westwater anticipates commencing a strategic financing review process for the Coosa Deposit. This strategic financing review process will seek to identify financial investment sources and partners for the Coosa Deposit and may include review of strategic investment partners or other strategic transactions.

Westwater Resources Inc. 100 % Indirect
On April 23, 2018, Westwater acquired a 100% interest in Alabama Graphite Corp. as part of a strategic decision to refocus the Company to supply battery manufacturers with low-cost, high-quality, and high-margin natural graphite products. As a result of that business transaction, Westwater became the owner of the Project.

Deposit type

  • Metamorphic hosted

Summary:

Graphite deposits occur in three forms: flake graphite, vein graphite, and amorphous graphite.

Landis (1971) tentatively concluded that graphite formation is primarily dependent on metamorphic temperature and forms above 400°C, with pressure and variation in starting material constituting secondary controls.

The Coosa graphite deposits are flake graphite deposits in high grade metamorphic rocks. They are associated with anomalous vanadium, including the vanadium-mica roscoellite, and nickel, as well as other elements.

Geological mapping of the Coosa resource grid was carried out by Alabama Graphite geologists based on stream sections, road cuts, drill pads, and trenches. The main graphite schist trends northeast and to the south changes to north-south, and joins with another unit of graphite schist to the east. There is garnet schist on the east side of the graphite schist, which dies out to the south. These features may be interpreted as an anticline plunging at a low angle to the south with a core of garnet schist overlain structurally by graphite schist. The graphite schist is underlain structurally on the west side by quartz-muscovite-biotite-graphite schist.
