Atna Reports Strong Production at Briggs Mine

October 6, 2010

GOLDEN, Colo., Oct. 6 /PRNewswire/ — Atna Resources Ltd. (“Atna”) – (TSX: ATN – OTC Bulletin Board: ATNAF) is pleased to report strong operating results at the Briggs Mine for the third quarter ending September 30, 2010. The following results are in comparison to results reported for the second quarter ending June 30, 2010.

  • Gold contained in mined ore increased by 88% to 12,390 ounces
  • Total tons mined increased by 5% to 2.7 million short tons
  • Gold in crushed ore placed on the leach pad increased by 44% to 10,300 ounces
  • Gold sales increased by 10% to 6,190 ounces
  • The average price for gold sold was $1,201, an increase of 3%
  • Gold dore produced for the first three quarters of 2010 totaled 17,160 ounces

“We are very pleased with operations at Briggs for the third quarter. Mine productivity has improved and we expect to see continued strong production results in the fourth quarter. Through September 30, we have placed 6,000 ounces on the leach pads that will be recoverable in the fourth quarter. This is over 50 percent of our estimated quarter’s production. We remain confident that our second quarter estimate for gold production in 2010 of 25,000 to 30,000 ounces at Briggs will be achieved,” stated James Hesketh, President & CEO.

Strong production results from the mine are a result of increased mining productivity and a 41 percent increase in ore grade for the period. Improved mine productivity resulted from a stronger focus on equipment availability and opening up new working faces which made the available equipment more efficient. Mine activities in the first half of the quarter focused on waste stripping to increase ore sources. This resulted in increased ore tons and grade delivered to the crusher in the second half of the quarter. Recovered gold production lagged ore deliveries for the third quarter as initial gold recovery from ores placed on the leach pad occurs 30 to 40 days after placement. The majority of the ounces placed in the second half of the third quarter will be recoverable in the fourth quarter.
