Atna Drills 385 Feet Grading 0.053 oz/ton Gold at Reward Project

 
Golden, CO - Atna Resources Ltd. ("Atna" or the "Company") (TSX:ATN/ OTCBB:ATNAF) is pleased to report strong gold intercepts at its Reward Gold Mine, Nye County, Nevada. Atna completed the 2011 drill program of fifteen drill holes totaling 8,880 feet (2,700 m) in mid-October and has now received assay results on all drill holes in this campaign.

Highlights of the final drill results include:
  • 385 feet grading 0.053 oz/ton gold, including 90 feet grading 0.130 oz/ton gold (117.3 m grading 1.80 g/t, including 27.4 m grading 4.46 g/t) in hole number RW11-032
  • 150 feet grading 0.026 oz/ton gold including 55 feet grading 0.040 oz/ton gold (45.7 m grading 0.89 g/t, including 16.8 m grading 1.36 g/t) in hole number RW11-031
  • 90 feet grading 0.034 oz/ton gold (27.4 m grading 1.17 g/t) in hole number RW11-030
"The 2011 drill program produced very encouraging results and should help to strengthen the economics of the project. Gold mineralization along the southeastern 1,000 feet (305 m) of the main deposit has been expanded to the east by up to 200 feet (60 m) and remains open to further extensions. This program clearly indicates the potential to expand and increase mine life at Reward," said James Hesketh, President & CEO.

Gold mineralization is hosted within gently dipping siltstone units of the Woods Canyon Formation and the Good Hope fault zone. The Good Hope fault zone is a high-angle normal fault and is considered to be the main hydrothermal feeder for gold mineralization at the project.
