Ladies and Gentlemen:

We are acting as counsel to Westwater Resources, Inc., a Delaware corporation (the “Company”), in connection with the proposed sale of up to $10,000,000 of the Company’s common stock, par value $0.001 per share (the “Common Stock”), by the selling stockholder (the “Selling Stockholder”) identified in the Registration Statement (as defined below). The shares to be sold by the Selling Stockholder are included in a registration statement on Form S-1 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission on October 28, 2019 (as amended, the “Registration Statement”). The Registration Statement relates to the registration of up to 959,000 shares of Common Stock (the “Purchase Shares”) that may be issued and sold to the Selling Stockholder from time to time by the Company, pursuant to a purchase agreement dated June 6, 2019 between the Selling Stockholder and the Company (the “Agreement”). The term “Purchase Shares” shall include any additional shares of Common Stock registered by the Company pursuant to Rule 462(b) under the Act in connection with the offering contemplated by the Registration Statement. This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. § 229.601(b)(5), in connection with the Registration Statement.

For purposes of this opinion letter, we have examined copies of such agreements, instruments and documents as we have deemed an appropriate basis on which to render the opinions hereinafter expressed. In our examination of the aforesaid documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all documents submitted to us, the authenticity of all original documents and the conformity to authentic original documents of all documents submitted to us as copies (including pdfs). As to all matters of fact, we have relied on the representations and statements of fact made in the documents so reviewed, and we have not independently established the facts so relied on. This opinion letter is given, and all statements herein are made, in the context of the foregoing.

This opinion letter is based as to matters of law solely on the Delaware General Corporation Law, as amended. We express no opinion herein as to any other statutes, rules, or regulations.

Based upon, subject to and limited by the foregoing, we are of the opinion that the Purchase Shares will be duly authorized for issuance and, when issued, delivered and paid for in accordance with the terms of the Agreement, will be validly issued, fully paid and non-assessable.

This opinion letter has been prepared for use in connection with the Registration Statement.  We assume no obligation to advise of any changes in the foregoing subsequent to the date of this opinion letter.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the Registration Statement and to the reference to this firm under the caption “Legal Matters” in the prospectus constituting a part of the Registration Statement.  In giving this consent, we do not thereby admit that we are an “expert” within the meaning of the Act.

Very truly yours,
