ATNA RESOURCES LTD.

Atna Resources announce the results of its second phase of drilling into the newly discovered Briggs Main Deep area at its Briggs Mine, Inyo County, California. The results of the second phase of drilling, targeting the Briggs Main Deep, continues to indicate a significant zone of gold mineralization located directly beneath the current mineable reserves at Briggs Mine. The eight new reverse circulation rotary drill holes (7,450 feet) have extended the BMD mineralization to the north, south, and east of the previous drilling results. Mineralization has now been intersected in drill holes over a north-south distance of 1,000 feet and an east-west distance of 750 feet. Thickness of the sub-horizontal mineralized zone varies significantly within the drilled area ranging from 25 feet in the southern most intercepts to over 250 feet in the northern portion of the zone. The BMD mineralization remains open to the east and north.
