Focus Will Be Entirely on Graphite Development Going Forward

Patent Application Submitted for Graphite Purification Technology

Company Anticipates $4 Million Annual Cost Reduction

CENTENNIAL, Colo.--(BUSINESS WIRE)--#graphite--Westwater Resources, Inc. (Nasdaq: WWR), an energy materials development company, today announced a binding letter of intent to sell its uranium assets located in New Mexico and Texas to enCore Energy Corp. of Vancouver, British Columbia, Canada, a Toronto Venture Exchange-listed company (TSX.V:EU). Total compensation accruing to Westwater as part of the deal is expected to be in excess of $1.95 million in enCore shares and royalties from future production from the New Mexico properties. All remaining reclamation liabilities and bonding obligations for the Company�s Texas uranium properties will be transferred to enCore at the time of sale, with the transaction expected to close on or before December 31, 2020. This transaction is subject to further due diligence, the execution of a definitive agreement, and other customary conditions. Westwater is retaining its uranium interests in Turkey, which are subject to an ongoing international arbitration proceeding.

Christopher M. Jones, President and Chief Executive Officer of Westwater said, �We are happy to place these uranium assets in the hands of a company like enCore where they can be developed further as part of a larger, consolidated land position, while we devote our full focus and attention on advancing our battery-grade graphite product business. We are excited to continue our participation in the uranium sector as a significant shareholder of enCore and royalty holder, while transferring responsibility for remaining reclamation to them. We believe that the enCore organization has a strong foundation of highly experienced former operators of uranium mines and processing facilities, and we are putting this business in good hands. At the same time, we expect to save over $4 million per year for the next several years in land payments, reclamation expenses and operating costs associated with the uranium properties � money that can be used for our Coosa Graphite Project.�

�The Coosa Graphite Project in Alabama is perfectly timed to take advantage of the advances in the electrification of our transportation system and grid electricity storage for renewable energy here in the United States and the rest of the world. These systems need graphite as a critical ingredient � and our development plan puts battery graphite in the marketplace and accelerates Westwater�s path to cash flow. Getting our foot in the door early is good for business and good for our shareholders.�

William M. Sheriff, Chairman of enCore Energy Corp said, �Upon the completion of the reclamation activities commenced by Westwater, we look forward to the revitalization of the licensed Rosita plant in Texas, located in one of the most progressive uranium jurisdictions in the United States. In addition, with the New Mexico assets, enCore is the first company to control and consolidate the leading land position in New Mexico, the largest uranium belt in the United States. With our team�s track record and expertise, we have the capacity to take these valuable assets and create a leader amongst domestic uranium producers.�

Graphite Purification Patent Application

Westwater has applied for a Provisional Patent with the U.S. Patent and Trademark Office for its proprietary graphite purification technology. This proprietary process, which does not utilize hydrofluoric acid, is a purification methodology that has a more sustainable footprint than those currently used in China and elsewhere. Our purification process is an integral component in our pilot plant program, which we announced on August 8, 2020.

Commenting on this important development, Chris Jones stated, �This patent application, and all the hard work and innovation that went into developing this technology by our technical teams, is another example of Westwater�s dedication and energy � characteristics that we believe will propel the Company further down the road in the green energy storage space that our graphite business is designed to serve.�

The invention claimed in the provisional patent application relates to a method of obtaining highly purified graphite � having a graphitic carbon (Cg) grade of at least 99.9% � from a natural flake graphite concentrate sample. The method consists of three steps: (1) caustic roasting of the graphite concentrate sample; (2) acid leaching of the roasted sample; and (3) thermal treatment of the sample. Additional steps involving water washing and drying are included in some methods. The methods provided in the application may further include any combination of varying the weight percentage of the caustic solution, varying the temperature of and time for the caustic roasting, varying the temperature of and time for the acid leaching, and/or varying the temperature of, time for, and the atmosphere used in the thermal treatment.

Pilot Plant Update

On August 20, 2020, Westwater announced it had engaged Dorfner Anzaplan of Hirschau, Germany to execute its pilot plant that will advance the development of processes needed to purify graphite concentrates and to produce Westwater�s battery grade products: ULTRA-PMG^TM, ULTRA-CSPG^TM and ULTRA-DEXDG^TM. Dorfner Anzaplan is an internationally recognized and highly regarded organization that specializes in high-purity industrial and strategic metals businesses. Dorfner Anzaplan will employ state-of-the-art analytical methods and facilities and use innovative processing technologies to provide effective solutions tailored to Westwater�s requirements. Planning and construction of an operational pilot plant is underway.

Westwater has developed proprietary processes for the production of battery grade graphite from non-Chinese sources that are designed to manufacture high performing products while ensuring a sustainable environmental footprint and low production costs. Test work on the products from these processes has been performed already in laboratories in Germany and the United States, and those results show that the performance of the Coosa Project�s graphite is on par with or exceeds that of currently available battery products. The next step in Westwater�s development process is the operation of a pilot plant that is designed to process approximately 30-tonnes of graphite concentrate and to produce more than ten metric tons of ULTRA-PMG^TM, ULTRA-CSPG^TM and ULTRA-DEXDG^TM products, now scheduled for later this year and the first part of 2021.

The Company will provide updates on this exciting project as they occur over the coming weeks and months.

Return of Lithium Claims

Westwater has returned its lithium claims in Nevada and Utah to the United States government, thereby focusing all financial and technical resources on the continued development of its graphite business. Estimated savings from the return of these claims will be on the order of at least $200,000 per year.
