Our current geographic focus for future corporate growth is the State of Nevada. Nevada is highly prospective for gold; it has a stable regulatory environment and a well established mining sector. Nevada is the third largest producer of gold in the world behind South Africa and Australia. In addition to our Reward Project, we have seven exploration properties in Nevada. Please visit our Nevada Projects page for more information on each property. The Reward project is our most advanced, 100% Atna owned project in Nevada.

REWARD GOLD PROJECT

FEASIBILITY STUDY (NI 43-101-Compliant)

Atna's wholly owned subsidiary Canyon Resources completed a feasibility study for the Reward gold project in February 2008. The feasibility study, prepared by Chlumsky, Armbrust & Meyer LLC of Lakewood, Colorado, envisions development of a conventional open pit mining, ore crushing, and heap leach gold production operation. The study recommended development of the project. Proven and probable mineral reserves estimated in the feasibility study total 5.2 million tons averaging 0.027 ounces per ton (opt) containing 138,000 ounces of gold based on a gold price of US$575 per ounce and a strip ratio of 2.0 tons of waste per ton of ore.

The Reward operation is expected to produce approximately 117,000 ounces of gold over a four year mine life at an estimated average cash cost 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 of 13.2% at a $700 gold price. The feasibility study includes capital costs for crushing and process plants, facilities and infrastructure, mining fleet and pre-production stripping of $24.3 million. Break-even full cash 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% and an undiscounted net cash flow of approximately $36 million without allowance for reserve expansion.

The feasibility study also developed an alternative case using a $700 pit design that contains in-place mineralized material 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 $449 per ounce generating an IRR of 11% 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% and an undiscounted net cash flow of $40.3 million.

We've entered into an agreement to lease water rights for use in potential future operations at Reward and have extended our land positions around the site. We've completed a detailed leach pad design, a waste dump stability analysis and have initiated a geotechnical study. Cuttings from our drilling program were utilized to conduct bottle roll leach recovery tests which confirmed past test results.

A Plan of Operations and Reclamation Plan for the Reward Project were submitted to the Las Vegas office of the BLM and to the Nevada Bureau of Mining Regulation and Reclamation in November 2006. This submittal initiates the permitting process for Reward and forms a basis for the development of operating permits.

The Reward property contains an intensely sheeted, north-south-trending shear zone and associated veins, which vary from steeply dipping to modest dip (45 degrees) to the east, within a sequence of quartzitic beds, schists, and dolomites. The Reward gold-mineralized structure has been sampled by more than 308 holes totaling 106,965 feet drilled by a number of mining entities over the past 15 years, including 21 holes for 6,140 feet drilled by us in 2006. Gold mineralization has been encountered over a strike length of more than 2,400 feet and to a depth of 400 feet along the Reward structure. The width of mineralization within the structural zone ranges from a few feet to up to 200 feet. The mineralized structure remains open and untested at depth and along strike to the south.
