Atna Commences Small Scale Production at Pinson

GOLDEN, Colo., June 24, 2014 /PRNewswire/ -- Atna Resources Ltd. ("Atna" or the "Company") (TSX:ATN /OTCQB:ATNAF) is pleased to report that it has commenced small scale mining and gold production at its Pinson underground mine near Winnemucca, Nevada. Pinson entered into a contract mining agreement on a risk-sharing basis with Small Mine Development LLC of Boise, Idaho and renewed its prior gold ore purchase and sales agreement with Newmont. The first shipment of ore has been mined and sold to Newmont's Twin Creeks oxide mill.

Initial mining started in a previously developed oxide ore stope in the Ogee zone. Two additional oxide stopes have been identified for mining over the next quarter with one of these stoping areas to be mined by long-hole stoping, a bulk-mining method versus the selective underhand cut-and-fill mining method previously used at Pinson. Ore will be screened on surface to eliminate waste and upgrade the average grade shipped as was learned to be effective in prior operations.

Atna plans to mine previously developed ore zones at Pinson with minimal investment requirements, and to make regular ore sales as tonnages are produced. The Company does not intend to provide forward guidance on production, but will report results periodically as the program proceeds. Mining rates may be increased with experience and as justified by the gold market and profitability of Pinson-underground operations.        

Work is progressing on producing updated resources, reserves and long-term mine plan for the Pinson underground operation. In addition, work is nearing completion on an open pit, heap leach mining study for the private land sections at Pinson. Atna plans to combine these two studies into a single NI 43-101 compliant report for release. 

This press release was prepared under the supervision and review of William Stanley, V.P. Exploration of Atna, a Registered Member of the Society for Mining, Metallurgy, and Exploration (No. 3069054), a Licensed Geologist and qualified person, as defined in NI 43-101, who has verified the authenticity and validity of the technical information contained within this news release.
