Atna Cuts 120 feet Grading 0.057 oz/ton Gold at Reward Gold Project


GOLDEN, Colo., March 25, 2013 /PRNewswire/ -- Atna Resources Ltd. ("Atna" or the "Company") (TSX:ATN/OTCQB:ATNAF) is pleased to provide results from the remaining drill holes in the recently completed Reward gold project drilling program near Beatty, NV. The drilling program is designed to expand the existing resource and reserves at Reward. Fourteen holes were completed in the program for a total footage of 9,013 feet (2,747 m). Assays have been received on all holes with continued promising results in the new zone announced last month (February 25th, 2013 press release).

Highlights from the new drill results include:

  • 145 feet (44.2 m) grading 0.020 oz/ton gold (0.68 g/t gold) in hole RW13-038
  • 115 feet (35.1 m) grading 0.020 oz/ton gold (0.68 g/t gold) in hole RW13-042
  • 80 feet (24.4 m) grading 0.041 oz/ton gold (1.42 g/t gold) and 50 feet (15.2 m) grading 0.016 oz/ton gold (0.55 g/t gold) in hole RW13-049
  • 120 feet (36.6 m) grading 0.057 oz/ton gold (1.95 g/t gold) which includes 45 feet (13.7 m) grading 0.109 oz/ton gold (3.73 g/t gold) in hole RW13-050.

"The second round of results along the eastern and southeastern flank of the main Reward gold deposit has confirmed the presence of a new gold zone at Reward. The zone has now been traced for over 800 feet (240 m) along strike and remains open to the north, south and down dip to the east. An additional drilling program is being designed to follow-up on these promising results," states Atna's President & CEO, James Hesketh.

* True thickness is an estimated value based upon interpreted strike and dip of the mineralized zone and drill hole intercept orientation through the mineralization. The actual thickness may be less than or greater than the estimated value given in the table if geologic interpretation changes with increased drill hole density.

Gold mineralization at Reward is controlled principally by the Good Hope fault zone; a sheeted, steeply dipping, north-south-trending quartz-vein zone. Adjacent to the Good Hope fault, the phyllitic quartzite, siltstone, and shales dip moderately to the east (45 degrees) and are host to more disseminated gold mineralization associated with narrow iron oxide veinlets (after pyrite) and minor quartz veining. The Reward gold deposit has been sampled by more than 350 holes totaling more than 130,000 feet drilled by a number of mining entities over the past 15 years including the Company. Gold mineralization has been encountered over a strike length of more than 2,400 feet and to a depth of 750 feet along the Good Hope structure. The width of mineralization within the structural zone ranges from a few feet to up to 200 feet and the bedded zones along the southeastern flank of the main Reward deposit attains thicknesses in excess of 300 feet. The Reward gold project has received both US and State permits that will allow construction of the mine.

Analytical results contained within this press release were completed by standard fire assay methods with an atomic absorption finish by American Assay Laboratories, an independent, IAS accredited Testing Laboratory (ISO/IEC Standard 17025:2005) serving the mining industry of northern Nevada located in Sparks, Nevada.
