Golden, CO - Atna Resources Ltd. ("Atna") - (TSX:ATN) is pleased to announce that it has filed an NI 43-101 technical report ("Technical Report") titled "NI 43-101 Technical Report, Reward Gold Project, Nye County, Nevada." The Technical Report, prepared by Chlumsky, Armbrust & Meyer LLC of Lakewood, Colorado, envisions development of a conventional open pit mine, ore crushing, and heap leach operation. The Technical Report recommends development of the 100 percent owned Reward Gold Project and Atna is working to fulfill permitting requirements to enable development of the project.

Definitions used in the Technical Report and in this release are consistent with those adopted by the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Council in December 2005, as amended, and prescribed by the Canadian Securities Administrators' National Instrument 43-101 and Form 43-101F1, Standards of Disclosure for Mineral Projects.

The report details an estimate of mineral reserves and mineral resources as summarized in the tables below:

1) Gold price of US$575 per ounce
2) Strip ratio of 2.2 tons of waste per ton of ore
3) Included within total mineral resource
4) Internal economic cutoff grade of $0.01 per ton
5) Gold recovery = 82 percent (including residual)

1) Cutoff Grade = 0.010 oz/ton gold

The measured and indicated resources stated above include reserves, which are a sub-set of resources. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves.

Not included in the above mineral reserves are an additional in-pit inferred resource above the internal cutoff grade and estimated to be 271,000 tons grading 0.018 ounces per ton ("opt"), and containing approximately 5,000 ounces of gold. The Reward gold resource is open along strike and down-dip which will require additional exploration drilling to evaluate.

The report discusses 2 alternative development scenarios:

1) US$525 PIT DESIGN

The Reward operation is expected to produce approximately 117,000 ounces of gold over a four year mine life at estimated average cash costs of $409 per ounce of gold produced. This production would provide an undiscounted cash flow of $14.6 million and an internal rate of return ("IRR") of 13.2 percent at a $700 gold price. The report includes capital costs for crushing and process plants, facilities and infrastructure, mining fleet and pre-production stripping of $24.3 million. Break-even full cost inclusive of capital is $564 per ounce. At a gold price of $900 per ounce, the project would develop an internal rate of return of 32.8 percent and an undiscounted net cash flow of approximately $36 million without allowance for reserve expansion.

2) US$700 GOLD PRICE PIT DESIGN

The report developed an alternative case using a $700 gold price pit design that contains a measured and indicated resource of 6.4 million tons grading 0.025 opt with a waste to ore strip ratio of 2.2 using a variable cutoff grade. This case would require an additional $1.1 million in pre-production capital over the base case. This larger pit is expected to produce 134,100 ounces of gold over a five year mine life at an estimated average cash cost of $412 per ounce generating an IRR of 11 percent and an undiscounted net cash flow of $15.4 million using a $700 gold price. At a $900 gold price, this case produces an IRR of 30 percent and an undiscounted net cash flow of $40.3 million.

Initial capital costs can be reduced in both the $575 and $700 cases by using contract mining. Based on actual contract mining quotes, initial capital purchases for mining equipment and shops can be reduced by approximately $7.5 million, while overall life-of-mine mining costs are increased by approximately $5.3 million for the $575 pit case and higher in the $700 pit case. Further studies will be completed and reviewed comparing the use of contract mining versus owner mining prior to development.

Mining operations at Reward would utilize conventional 100-ton open pit trucks and compatible loaders. Mined ore will be crushed to minus 3/8 inch and placed on a lined pad for leaching and gold recovery. Process solutions will be captured in solution tanks and circulated through activated carbon to capture contained gold. This loaded carbon would subsequently be dewatered, packaged, and transported for final gold recovery to either the CR Briggs Mine in Inyo County, California or to a third party processing facility.

The project has been carefully designed to create the smallest environmental footprint possible and the permitting process is well advanced. Final reclamation and closure cost, which is included in overall production cost, is estimated at approximately $2.5 million for the base case. The cost for reclamation and closure bonds of approximately $5.3 million was estimated using the State of Nevada statutory cost estimating model and is subject to final approval by State regulatory authorities. Bonds may be posted using a number of financial instruments including cash. This amount would be in addition to the capital estimates stated above.
