Atna Receives Large Mine Expansion Permit for Pinson

GOLDEN, Colo., Feb. 5, 2013 /CNW/ - Atna Resources Ltd. ("Atna" or the "Company") (TSX:ATN/OTCQB:ATNAF) is pleased to announce that modification of the Pinson Mine Water Pollution Control Permit has been approved and became effective February 5, 2013. This permit approval authorizes Atna to construct and operate the Pinson Mining Project and to extract by underground mining up to 400,000 tons of ore per year for offsite gold processing. The modification replaces the former Pinson Exploration Project permit which allowed the mining of up to 36,500 tons of ore per year.

"The approval of this permit for our Pinson Gold Mine is a major development for Atna's future growth and profitability. It will allow us to increase mining levels up to our ultimate goal of 1,000 tons of ore production per day. Gold production at Pinson is expected to steadily increase through the year with significantly higher levels of production in the second half of 2013", states James Hesketh, President & CEO.

Work at Pinson is focused on primary development of spiral ramp access and multiple laterals to ore stoping areas, along with development of underground infrastructure including ventilation, water, compressed air, maintenance facilities and ground support. In addition, ore production and backfill operations in developed stoping areas are expanding. The construction of surface infrastructure facilities and dewatering wells is also underway with many tasks nearing completion. Additions to staff and personnel are ongoing to support increased levels of operation and development.
