Atna Resources Reports 2013 Production Results

GOLDEN, CO - Atna Resources Ltd. reported operating results for 2013. Atna's gold sales totaled 37,080 ounces for the year, which includes 31,700 ounces sold from the Briggs Mine and approximately 5,380 payable ounces from the sale of ores mined during development at the Pinson underground mine.

The Briggs Mine successfully reduced cash and all-in sustaining costs in response to declining gold price. Production was lower than projected due to high waste stripping during the first half of the year and intermittent mechanical and productivity issues in the second half of the year. At the Pinson Mine, declining gold price and a shortfall in working capital caused mine development to be halted prior to achieving sustainable commercial production. Mine dewatering and maintenance operations are ongoing at Pinson.

James Hesketh, President & CEO said, 2013 was a challenging year for Atna. Our Company has redoubled its efforts to improve all facets of operations at the Briggs Mine and throughout the company. Atna's primary goal in 2014 is to improve productivity at the Briggs Mine and to continue reducing production costs. Our 2014 gold production estimate at Briggs is 40,000 to 45,000 ounces based on the expectation of higher ore grades in the 2014 mine plan. Key development activities for 2014 include completing a pre-feasibility study for the Mag open pit adjacent to the Pinson underground and modifying the underground mine plan at Pinson based on experience gained in 2013."
