Atna Resources Ltd. To Be Delisted From TSX

GOLDEN, Nov. 25, 2015 - Atna Resources Ltd. (TSX: ATN and OTCQB: ATNAF) (the "Company" or "Atna") today announces that as a result of the commencement of proceedings under chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the District of Colorado ("the Bankruptcy Court"), and ancillary recognition proceedings in Canada pursuant to the Companies' Creditors Arrangement Act, it fails to meet the continued listing requirements of the Toronto Stock Exchange ("TSX"). As a result, the Company has received a notice from the TSX that the common shares of the Company will be delisted by the close of the market on December 29, 2015.

The Company's common shares were suspended on November 19, 2015 and will remain suspended from trading until delisting. The Company has commenced discussions with the intent to potentially have its common shares listed on another recognized exchange. However, there can be no assurance that a listing on another exchange will be obtained before the Company is delisted from the TSX.

On Wednesday, November 18, 2015, Atna Resources, Inc. and 6 affiliates (Atna Resources Ltd., Canyon Resources Corporation, CR Briggs Corporation, CR Kendall Corporation, CR Montana Corporation and Horizon Wyoming Uranium, Inc.) (collectively, the "Debtors") each filed a voluntary petition for relief under chapter 11 of the United States Bankruptcy Code. The Cases are pending before the Honorable Sidney B. Brooks in the United States Bankruptcy Court for the District of Colorado (the "Bankruptcy Court") under jointly-administered case no. 15-22848.  Following hearings on Friday, November 20 and Monday, November 23, 2015, the Bankruptcy Court authorized the Debtors to borrow up to $4 million in new financing from its existing secured lender, Waterton Precious Metals Fund II Cayman, LP, on a senior secured priming and superpriority basis, and also approved certain customary "first day" motions for relief on an emergency basis.  The Debtors are continuing to operate their businesses as debtors in possession during their bankruptcy cases. Additional information is available about the Debtors' bankruptcy cases at no charge at: www.upshotservices.com/atna.

The Company continues to focus its efforts on the restructuring and refinancing of its outstanding debts.
