Westwater Resources Announces First Quarter March 31, 2021 Results

Pilot Program Has Processed 13 Metric Tonnes of Battery Graphite

Feasibility Study Underway with Samuel Engineering

Exploration and Development Drill Program Underway at Coosa Graphite Deposit

Westwater Resources Inc. (NYSE American: WWR), an explorer and developer of U.S. mineral resources essential for batteries for energy storage, today announced its results for the quarter ended March 31, 2021.

"As I mentioned in our 2020 year-end earnings release in February, we had an immensely successful 2020, and I am very proud to state the first quarter ended March 31, 2021 has continued this trend," said Chris Jones, CEO of Westwater Resources. "The President signed a declaration naming graphite critical to the safety and security of the United States. We believe this declaration, and the actions expected to follow it, will have a significant positive impact on our ability to develop and build our graphite business."

"The definitive feasibility study for the Coosa Graphite Project processing facility is underway and, when completed at mid-year 2021, will provide detailed specifications and inform the detailed engineering work we need to execute prior to construction," Jones continued. "This design work is expected to be used to start construction of the plant toward the end of 2021. At this time, we have processed over 13 metric tonnes of our battery product material during our pilot program, and the three products we produced can go to potential customers for testing."

"Exploration and development drilling on the Coosa Graphite Deposit began in April 2021," Jones concluded. "We are expanding our knowledge of the graphite deposit with this 10,000-foot program. Assays for both graphite and vanadium, an important alloy material for high strength and tool steels, will be performed and integrated into our geologic model, then used to re-optimize the extraction of the resource and re-estimate the deposit economics. I'm thrilled with the progress we're making, none of which could have been accomplished without the hard work of our dedicated and innovative management team and drilling contractor.

Financial Summary

• Net Cash Used in Operations. Net cash used in operating activities was $4.9 million for the three months ended March 31, 2021, as compared with $3.5 million for the same period in 2020. The $1.4 million increase in cash used was primarily due to increased graphite product development expenses, general and administrative expenses, and arbitration costs in 2021 compared to 2020, offset by the elimination of costs from discontinued operations and an increase in cash from working capital items of $0.6 million.
• Product Development Expenses. For the three-month period ended March 31, 2021, $1.8 million was spent on product development. Of that, approximately $1.2 million related to the operation of our graphite processing pilot program with the remaining attributable to product testing and other lab work, shipping, travel, and other auxiliary costs associated with the Coosa Graphite Project.
• General and Administrative Expenses. For the three months ended March 31, 2021 general and administrative expenses increased by $0.3 million from the respective period in 2020. The difference is primarily due to increased legal and consulting expenses related to the Company's Coosa Graphite Project.
• Arbitration Costs. During the first quarter of 2021, Westwater incurred arbitration related legal and expert consulting costs of $1.5 million. This represents an increase of 114% or $0.8 million in costs associated with the Request for Arbitration against The Republic of Turkey compared to the first quarter of 2020.
• Net Loss. Our consolidated net loss for the three months ended March 31, 2021 was $5.4 million, or $0.19 per share, as compared with a consolidated net loss of $3.3 million, or $0.82 per share for the same period in 2020. The $2.1 million increase in our consolidated net loss from the respective prior period was largely the result of an increase in product development costs, general and administrative costs and arbitration costs, offset by the elimination of $1.1 million in costs from discontinued operations.
• Cash and Working Capital. On March 31, 2021 the Company's cash balances were $117.9 million and the Company had working capital of $115.1 million, which represented an increase of $66.8 million from a working capital balance of $48.3 million at December 31, 2020. This increase in working capital was primarily the result of a higher cash balance from the sale of shares of common stock for net proceeds of $72.2 million pursuant to our Controlled Equity Offering^SM Sales Agreement with Cantor Fitzgerald & Co. and our Purchase Agreement with Lincoln Park Capital, LLC.
• Shares Outstanding. Total shares outstanding are 32,336,315 as of May 12, 2021.
