Montreal. April 14th /CNW Telbec/ - The concerned shareholders (the "Concerned Shareholders") announced today that they have mailed an information circular (the Circular") to the shareholders of Atna Resources Ltd. ("Atna") (TSX:ATN) seeking to elect three highly qualified nominees to the Atna board of directors (the "Board") at the Annual General Meeting of Shareholders to be held on May 6, 2011 (the "Meeting") to replace three members of the current Board.

The reasons the Concerned Shareholders are taking this action include the following:

*The current Board has delivered poor operating results and has issued common shares at historically low prices and at a significant discount to the market. Atna's share price has declined approximately 65% since its high in 2008.

*The value destruction to shareholders has been amplified by Atna completing a material financing at a significant discount to market.

*There is no indication whatsoever of any clear strategy for value enhancement and thus the Concerned Shareholders believe that a change of leadership is necessary.

"As the largest beneficial shareholder of Atna with over 12,310,133 shares of Atna, represently approximately 12.2% of the outstanding Atna shares, we are deeply concerned with the current leadership at Atna. The current Board has had its chance to bring value to Atna and has failed," stated Lloyd Miller of the Concerned Shareholders.

We ask for your support at the Meeting to replace three members of the current Board. We are nominating three new independent directors and are confident that they will bring accountability and leadership, add value and protect the interests of all shareholders. Our nominees will provide an injection of new ideas and strategic perspectives to Atna. We believe that by acting as the catalyst on behalf of the many suffering shareholders who want to see the decline in stock price halted and sustainable growth for Atna created, all shareholders will benefit
