Definitive Feasibility Study Completed – Contractor Proposals Initiated

Coosa Graphite Deposit Exploration to Continue for Remainder of 2021

Westwater Resources, Inc. (NYSE:AMERICAN) ("Westwater Resources" or "the Company"), a battery grade natural graphite development company, today announced its third quarter results for the period ended September 30, 2021 and provided an update on its Coosa Graphite Project ("Project").

During the nine months ended September 30, 2021, Westwater substantially completed its pilot program at facilities located in Amberg and Frankfort Germany, Chicago, IL, and Buffalo, NY. These facilities produced 13.2 metric tonnes of battery-grade graphite which provided product samples for testing by potential customers. Results from the pilot program operations were also used to inform and enhance design work for the commercial production facility, which was incorporated into the Definitive Feasibility Study ("DFS").

On October 11, 2021, Westwater Resources announced the results of the DFS pertaining to Phase I of the Project and a plan and design for Phase II of the Project at a pre-feasibility level ("PFS"). The capital costs of Phase I are estimated at $202 million and, after processing and purification, the Company expects to produce approximately 7,500 mt per year of purified graphite products. The capital costs of Phase II are estimated at $464 million and, after processing and purification, the Company expects to produce approximately 32,400 mt per year of purified graphite products from both phases. The Company intends to initiate a second DFS for Phase II upon completion and commissioning of Phase I.

On October 11, 2021, the Westwater Resources Board of Directors approved the construction and commissioning plan for Phase I of the Project. Construction activities are expected to begin before the end of 2021 and, beginning in early 2023, Phase I of the facility is expected to begin production operations with purchased graphite feedstock from outside sources until at least 2028; after 2028, Westwater Resources expects to produce graphite feedstock from its Coosa Graphite Deposit (near Rockford, AL). The Company anticipates financing Phase I expenditures using its current treasury and its existing finance facilities and may evaluate opportunities for project financing utilizing debt and equity instruments.

On October 13, 2021, Westwater completed the purchase of two buildings that total approximately 90,000 sq. ft. to support the Project. These buildings are adjacent to the graphite processing facility and will be used for the Project's administrative offices, laboratory and warehousing space. The purchase of these two buildings mitigates the need for certain construction activities.

Immediate next steps are the creation of the construction management team, which will be led by Chad Potter, Westwater Resources' Chief Operating Officer. Westwater Resources is in the process of soliciting proposals for construction management, engineering and procurement and for various contractors who will build and assemble the processing facility.

The Coosa Graphite Deposit exploration effort will continue throughout the remainder of the year, and the Company is actively drilling various targets to expand its knowledge of the geology and improve the existing resource model. In addition, vanadium mineralization is expected to be evaluated to ascertain any economic potential.

The President of the United States signed an executive order that seeks to provide for a more resilient supply chain to revitalize and rebuild domestic capacity of graphite and vanadium to reduce the United States' heavy dependence on China. Both minerals have been given critical metal status. With regard to graphite, the United States is almost 100 percent dependent on imports for battery-grade graphite, which is currently the primary anode material in the Lithium-Ion batteries that power smartphones, laptops, electric vehicles and store power generated from intermittent renewable energy sources. It is expected that the Project will ultimately supply natural flake graphite for beneficiation into battery-grade graphite for all types of batteries.

"The past nine months have been the most productive period in the Company's recent history," said Christopher Jones, CEO of Westwater Resources. "We completed our pilot program which produced 13.2 metric tonnes of graphite for final testing. We sent samples of our products to several customers for evaluation and are in contact with more potential customers. Our marketing efforts have resulted in engagements with potential customers with various battery manufacturers, original equipment manufacturers and battery developers."

"We are excited about the results of the DFS for the Project," Jones continued. "Our Board of Directors approved an investment of $202 million to build Phase I of our graphite processing facility, which is expected to be operational in early 2023. We also purchased two buildings which will support the development of the Project. These buildings are adjacent to the proposed site of the graphite processing facility and will be used for the Project's administrative offices, laboratory, and warehouse space. We have requested proposals from contractors, with construction expected to begin before the end of the year."

"Westwater Resources is grateful to the Governor of Alabama and other state and local leaders who worked with us to bring this unique graphite project to the state," Jones concluded. "We expect to benefit from the Alabama Jobs Act by securing certain tax credits and other incentives for over 10 years and the grant of land for the siting of the processing facility at minimal cost. At the Westwater Resources corporate level, this year we joined the Russell Microcap Index, an important milestone for us, and we transferred our listing to the NYSE American. All around, it's been a productive nine months for us."

Net Cash Used in Consolidated Operations

Net cash used in operating activities for the first nine months of 2021 increased $2.9 million compared to the same period in the prior year. The increase was due primarily to increased graphite product development, exploration, general and administrative, and arbitration costs in 2021.

Product Development Expenses

Product development expenses for the third quarter 2021 increased $0.2 million, compared to the same prior-year quarter. Product development costs were primarily comprised of expenses for our DFS, which began in February 2021 and was completed in October 2021, and our product development program continued through the first nine months of 2021. The product development program includes costs incurred to collaborate with outside experts for lab work, product testing and other auxiliary costs associated with the Coosa Project.

General and Administration Costs

General and Administration expenses for the third quarter 2021 increased $0.2 million compared to the same prior-year quarter, due primarily to higher stock compensation, and sales and marketing efforts that began in the third quarter of 2020 and have continued throughout 2021. These increases were offset partially by lower personnel costs due to the sale of Westwater's uranium business on December 31, 2020.

Net Loss

Net loss for the three months ended September 30, 2021, was $4.6 million, or $0.13 per share, as compared with a net loss of $9.8 million or $1.23 per share in 2020. The $5.2 million decrease in the net loss was due primarily to the elimination of costs from our former uranium business, and an unrealized gain related to the enCore common stock of $0.5 million. These decreases were offset partially by increases in general and administrative, arbitration, exploration and product development expenses.

Cash and Subsequent Financing Activity

As of September 30, 2021, the Company's cash balance was $119.0 million compared to $5.5 million as of September 30, 2020. The significant increase in 2021 was due to capital raises utilizing the company's financing facilities with Cantor Fitzgerald & Co. and Lincoln Park Capital LLC.

Subsequent to September 30, 2021, and through the date of this release, the company has sold 637,200 common shares for net proceeds of $2.3 million – pursuant to its financing facility with Cantor Fitzgerald & Co. – and liquidated its holdings of enCore common stock for net cash proceeds of $3.6 million.

Shares Outstanding

Total shares outstanding are 35.3 million as of November 11, 2021.
