DEREGISTRATION OF SECURITIES; TERMINATION OF REGISTRATION STATEMENT

This Post-Effective Amendment (the “Post-Effective Amendment”) constitutes the Post-Effective Amendment No. 1 to the registration statement on Form S-3 (File No. 333-151189) (the “Registration Statement”) filed by Uranerz Energy Corporation (the “Company”).

On January 5, 2015, the Company entered into an Agreement and Plan of Merger, as amended (the “Merger Agreement”), with Energy Fuels Inc. (“Energy Fuels”) and EFR Nevada Corp. (“Merger Sub”), a wholly owned indirect subsidiary of Energy Fuels. Pursuant to the Merger Agreement, on June 18, 2015, Merger Sub merged with and into the Company, and the Company continued as the surviving corporation and as a wholly-owned indirect subsidiary of Energy Fuels (the “Transaction”).

As a result of the Transaction, the offering pursuant to the Registration Statement has been terminated because the Company intends to deregister its Common Stock under the Securities Exchange Act of 1934, as amended. In accordance with undertakings made by the Company in the Registration Statements to remove from registration, by means of a post-effective amendment, any securities which remain unsold at the termination of the offerings thereunder, the Company hereby removes from registration all shares of common stock registered but not sold under the Registration Statement.
