Atna Resources Ltd. Reports on 2015 Mining Operations

GOLDEN, Jan. 18, 2016 - Atna Resources Ltd. ("Atna" or the "Company") announces that the Company sold approximately 31,470 ounces of gold for the year ended December 31, 2015, at an average gold price of $1,162 per ounce.

The Briggs Mine in Inyo County, California sold 19,526 ounces of gold. Mining and crushing operations were discontinued in July 2015, and production operations are now recovering gold from crushed ore inventory on the leach pads and contained in the processing plants. Year-end recoverable gold inventory remaining on the leach pads and in the plants is estimated at approximately 10,800 ounces to be recovered over the next two years. Gold production at Briggs will sequentially decline over time, as gold ounces are recovered and inventory balances are reduced.

Approximately 49,200 tons ore at an estimated grade of 0.360 ounces per ton was shipped from the Pinson Underground mine to Newmont's nearby Twin Creeks metallurgical facility in 2015. Subject to final settlements, Pinson sold an estimated 12,000 ounces of gold in 2015. Due to a lack of developed working faces and the working capital needed for further development, the Company has placed the Pinson mine on care and maintenance.

On November 18, 2015, Atna and its subsidiaries (together with Atna, the "Debtors"), filed voluntary petitions for relief under Chapter 11 of Title 11 of the United States Code in the United States Bankruptcy Court for the District of Colorado (the "Court"). Simultaneously with the Chapter 11 filings, the Debtors filed for ancillary relief in Canada pursuant to the Companies' Creditors Arrangement Act in the Supreme Court of British Columbia in Vancouver, Canada. On December 29, 2015, Atna Resources was delisted from the Toronto Stock Exchange. Further information concerning the Chapter 11 restructuring can be found at www.upshotservices.com/atna

Atna is currently in the process of marketing assets and properties for sale to meet its obligations to its creditors subject to approval by the Court. Maxit Capital LP, of Toronto, Ontario, is the investment banker assisting Atna in this process.
