COOSA Graphite-Vanadium Project

Vanadium and Westwater Resources

In early 2018 Westwater Resources’ technical staff carried out a review of historical data and geologic information derived from previous graphite exploration drilling and surface trenching programs at the Coosa Graphite Project in Alabama to determine the potential for the presence of substantial vanadium mineralization at the project, and this work identified significant potential for the discovery of vanadium mineralization in the project area. In late 2018 Company personnel carried out an extensive geochemical sampling program, collecting nearly 2,000 samples from many previously completed drill holes and trenches, to determine the presence and intensity of vanadium mineralization at the Coosa Project. The laboratory analytical results of this sampling program outlined wide-spread and strong vanadium mineralization in very close association with strong flake graphite mineralization at numerous localities within the project area.

The vanadium mineralization at the Coosa project occurs principally as the mineral roscoelite, a medium to dark green mica mineral that has been a global source for vanadium for more than one-hundred years. In addition to the presence of wide-spread vanadium mineralization in drill hole and trench samples, impressive zones of vanadium mineralization have been outlined in surface exposures at several locations within the project area, especially at the Roscoe Ridge exploration target.

The resultant technical analysis of the recently generated geochemical data highlights the high degree of prospectivity for the discovery of important levels of vanadium mineralizaion in association with equally important concentrations of flake graphite at the Coosa Project. A comprehensive exploration drilling program to further evaluate the vanadium resources, in addition to further evaluating the graphite resources of the Coosa Project is planned for late 2019 to follow-up on the results of geochemical sampling program, with the overall objectives of defining the magntude and intensity of the vanadium mineralization and associated graphite mineralization. Details of this program are discussed in the attached report on vanadium mineralization at the Coosa Project.
