Atna's Briggs Mine Reports Near Record Gold Ounces Mined

GOLDEN, CO - Atna Resources Ltd. reported that its Briggs Mine in Inyo County, California, mined over 5,700 ounces of contained gold in the month of June, the highest monthly total since September of 2010. This production is attributable to relatively high grade and strong ore availability from the Goldtooth South pit. Over the last six months Atna has invested in removing waste to access the underlying ore zone in the Goldtooth South pit. Over 5,100 ounces of gold was crushed and placed on the leach pad in June and the mine finished the month with a substantial stockpile of ore in front of the crusher.

"The Goldtooth South pit is performing well above expected levels and is providing a strong supply of ore at higher than average grades. Gold production is increasing with the increase in ounces placed on the leach pad. The Company expects Briggs gold production to fall within the range of its guidance of 35,000 to 43,000 ounces of gold for the year", states James Hesketh, President & CEO.
