Title: Atna Confirms New Gold Zone at Briggs Mine
Golden, CO - Atna Resources Ltd. ("Atna") - (TSX:ATN) is pleased to announce that the 2008/2009 exploration program at its Briggs Mine, which focused on targets with potential to extend the mine life has confirmed a deeper zone of gold mineralization beneath the current minable reserves in the Briggs Main pit. Atna has intersected this new Briggs Main Deep ("BMD") zone with 14 holes. The BMD drill holes have intercepted a gently dipping tabular zone over an area 800 feet long (north-south) by 700 feet wide. Apparent thickness of the zone ranges from 30 to 90 feet. The mineralization comes within 40 to 50 feet of the $750 ounce per gold design pit bottom. The BMD remains open for expansion to the north, south and east of the current intercepts.
The apparent thickness, grades, and broad distribution of the mineralization warrant a follow-up drill program to further define the BMD mineralization. The follow-up drilling at BMD will begin immediately following the drilling currently underway at the Cecil R satellite deposit to the Briggs Mine, located approximately four miles north of the Briggs Mine.
Atna's President and CEO, James Hesketh states, "These exploration results at Briggs Main Deep are very positive for the mine operation. If the next phase of drilling is successful, it may very well set the stage for adding significantly to the project's mine-life and profitability."

The Briggs Mine is located in Inyo County, California. The mine has open pit proven and probable reserves containing 267,000 ounces of gold with an average grade of 0.021ounce per ton (see press release dated February 18, 2009). An additional 650,367 tons of inferred resource containing 9,510 ounces of gold are contained within the pit shell limits, but are not included in the reserves. An updated NI 43-101 technical report is nearing completion and will be filed shortly. Open pit mining is underway and construction of the leach pad expansion has been completed. Crushing of stockpiled ore is expected to commence in March, with first gold production expected in April 2009.
The latest mine plan, excluding results for this drill program, projects a mine life of six years. The plan produces approximately 213,000 ounces of gold with an annual average full year production rate that ranges from 40,000 to 50,000 ounces per year during the years 2010 to 2013 with residual gold recovery in 2014. Gold production and sales for 2009 is expected to be over 20,000 ounces. Life-of-mine cash cost and full cost is projected to be $468 and $587 per ounce of gold, respectively. Life-of-mine pre-tax cash flow at a gold price of $750 is approximately $36 million net of capital recapture including sustaining capital and project closure costs. Total project pre-tax cash flow increases by over $20 million for every $100 increase in gold price.
Analytical results contained within this press release were completed by standard fire assay methods with an atomic absorption or gravimetric finish by Inspectorate America Corporation, an ISO certified, commercial analytical laboratory, located in Sparks, Nevada.
