Financial Results

At December 31, 2009, cash and cash equivalents totaled $13.1 million. Net cash used in 2009 for operating activities was $11.5 million, primarily consisting of the net cash loss from operations plus cash expended to build gold inventory-in-process of approximately 8,300 ounces with an inventory value of $6.9 million. Net cash used in investing activities of $6.0 million was due to purchases of property, plant and equipment at the Briggs Mine partially offset by proceeds from sales of assets. Net cash provided by financing activities of $13.8 million included $13.6 million in net proceeds from the issuance of the Gold Bonds and $1.4 million in net proceeds from the issuance of debentures partially offset by $1.1 million of payments on capital leases.

For the year ended December 31, 2009, Atna recorded a net loss of $6.0 million, or a loss per share of $0.07, on revenues of $8.7 million. This compares to net income of $15.8 million, or income per share of $0.20, on revenues of $0.2 million for the year ended December 31, 2008.

2010 Outlook and Objectives

• Further increase reserves/resources at both the Briggs and Reward mines
• The Briggs Mine is expected to produce positive cash flow in 2010 at a production target of 36,000 to 40,000 ounces of gold for the year
• Cash cost of production for 2010 is estimated to range from $600 to $625 per ounce of gold
• The 2010 goal for Briggs is to improve operational productivity while containing costs
• Complete infrastructure development at the Reward Mine and initiate project construction
• Complete an economic assessment of the Columbia project; continue permitting activities, baseline environmental sampling, metallurgical test work and initiate feasibility study
• Advance our opportunities arising from the interest held in the Pinson project

Briggs Mine, California (100%)

Commercial production at Briggs was declared on February 26, 2010, when the mine produced 80 ounces of gold per day for a period of greater than 30 days. At this production rate, the mine should produce sufficient cash flow to support both its operational and capital requirements, as well as support corporate overheads and return cash to the Company. The Briggs Mine is expected to produce positive cash flow in 2010 at a production target of 36,000 to 40,000 ounces of gold for the year. Cash cost of production for 2010 is estimated to decline to $600 to $625 per ounce of gold. The life of mine cash cost of production for current reserves is expected to range from $500 to $525 per ounce of gold.

Approximately $15.7 million in capital has been spent on the Briggs project through December 31, 2009. Capital spending for 2010 at Briggs is projected to be approximately $5.1 million, primarily for capital lease payments for major mining equipment and leach pad expansion. The pad expansion will add an additional seven million tons of leach pad capacity, which will be sufficient for all ores included in the current reserves.

Briggs Satellite Project (100%)

The Cecil R satellite project is located four miles north of the Briggs Mine. In March 2010, Atna declared a measured and indicated gold mineral resource containing 73,490 ounces and an inferred gold mineral resource containing 99,390 ounces (at a 0.01 oz/ton Au cut-off). Gold mineralization at Cecil R is hosted by the same geologic unit which hosts the nearby Briggs Mine gold deposit. The gently west dipping blanket-like zone of gold mineralization dips beneath Quaternary gravel cover and is distributed over an area 1,500 feet by 1,200 feet and has a thickness of 10 to 60 feet.

Work on the Cecil R project will continue during 2010 with economic evaluation of the newly defined resource, baseline environmental studies, infill drilling to upgrade resource classification, metallurgical testing, and permitting.

Reward Project, Nevada (100%)

The Company has received all major permits required to initiate development activities. A project manager has been retained for the project and an office has been opened in Beatty, Nevada. Immediate development activities include the completion of design engineering, development of contractor bid packages, and initial infrastructure development. Infrastructure development includes access road improvements, fencing, and placement of orders for long lead-time items, power line and water supply development. Anticipated cost for this phase of work will be approximately $3.0 million to be expended over a period of up to six months beginning in March 2010.

The Reward operation is expected to produce approximately 139,000 ounces of gold over a five year mine life at estimated average cash cost of $435 per ounce of gold produced. The feasibility study included capital costs of $24.3 million for crushing and process plants, leach pads, other facilities and infrastructure, mining fleet and deferred stripping. The Company is currently updating project capital and economic estimates to reflect higher gold prices, more accurate operating costs and increased gold reserves.

Pinson Project, Nevada (30%)

Atna owns a 30 percent equity interest in the Pinson joint venture. Pinson Mining Company ("PMC"), a subsidiary of Barrick Gold, owns 70 percent and PMC acts as operator of the project. The project is under further evaluation and Atna's share of project expenditures for 2009 and January 2010 totaled $0.5 million.

In 2009, PMC completed an in-house review of the project for both underground and open pit mining potential. They are currently reviewing their strategic options in regards to the project, which may include sale of their interest. Should they decide to sell their interest Atna retains a right of first refusal to match any offer within 60 days of that offer being presented to Atna. The 2010 budget for the Pinson project includes ongoing underground pumping and maintenance operations. Atna's share of the 2010 budget is $0.3 million.

In January 2010, Atna acquired a 1.5 percent net smelter return royalty ("NSR") on approximately four sections of land within the area of interest. The NSR was acquired from Barrick Turquoise Ridge Inc., a subsidiary of Barrick Gold. One of these sections contains gold resources previously announced by Atna.

Columbia Gold Property, Montana (100%)

Atna completed an NI 43-101 compliant Technical Report and Mineral Resource Estimate on the property in October 2009 (filed on SEDAR on October 21, 2009). The Technical Report declared a measured and indicated mineral resource of 741,700 ounces of gold and 2.1 million ounces of silver. Inferred mineral resource totaled 453,600 ounces of gold and 1.0 million ounces of silver (at a 0.01 oz/ton Au cut-off).

Montana state law currently prohibits the development of the Columbia project as an open-pit mine using cyanide based recovery technology. As a result, the Company is conducting conventional gravity and froth flotation recovery analysis on bulk samples from the mineralized zones. Initial results are promising, but additional test work and economic analysis is required to economically optimize this process route. The Columbia project will be required to complete an environmental impact statement and the permitting process before any development activities can take place on the property.

During 2010, the Company is planning to conduct additional metallurgical test work, environmental base-line studies, and a preliminary economic assessment of development alternatives for the property.
