Atna Provides Update on Exploration Venture Properties



    GOLDEN, Colo., Feb. 4 /CNW/ -- Atna Resources Ltd. ("Atna") - (TSX: ATN)
is pleased to provide an update on the activities at three of its exploration
ventures.
    

    Clover Gold Property

    
    Atna has received results from Yamana Gold Inc.'s ("Yamana") (TSX:
YRI)(NYSE:   AUY) exploration drilling program at Atna's Clover Project, Elko
County, Nevada. Yamana completed 10 reverse circulation rotary drill holes
(9,240 feet) in the Clover Hill area of the property. The 2008 drilling
focused on extending the Clover Hill structure to the north of Yamana's 2007
drilling which included 35 feet grading 0.302 ounce per ton ("oz/t") gold in
hole CV006. Yamana's 2008 drilling extends gold mineralization in this
structure an additional 650 feet to the north, clearly demonstrating new
discovery potential at the property. Drill results from Yamana's latest effort
are as follows:

    Yamana has informed Atna that it intends to prepare and submit a Plan of
Operations with the Bureau of Land Management commencing in early 2009 to
allow for further drill testing of the Clover Hill zone and other targets
within the Clover project. Project planning continues and permit applications
will follow as soon as drill hole planning is completed.
    

    
    The Clover prospect is a low-sulphidation, vein-hosted, epithermal gold
prospect located adjacent to the Midas trough within the Northern Nevada Rift.
 Clover's geologic setting is similar to Newmont Mining's Ken Snyder (Midas)
mine 8 miles to the east and also adjacent to the Midas trough.
    

    
    Yamana may earn a 51% interest in the Clover property by incurring
exploration expenditures of US$3,300,000 and making payments to Atna totaling
US$635,000 before June 19, 2010. Atna received a payment of US$150,000 in
January 2009, as a portion of the initial earn-in requirements. Yamana may
elect to increase its interest to 70% by completing a pre-feasibility study on
the property.
    

    
    All assay data from Yamana drill holes were completed by ALS Chemex and
ISO certified analytical laboratory. Assays were completed by standard fire
assay methods with an atomic absorption finish for both gold and silver with
over limit assays being re-assayed by standard fire assay with a gravimetric
finish.  Yamana and ALS Chemex have rigorous quality control protocols in
place to insure the quality of the analytical data reported in this press
release.
    

    Adelaide and Tuscarora Properties

    
    Atna has received 2,147,117 common shares of Golden Predator Mines Inc.
("Golden Predator") (TSX: GP) as an option payment under the terms of the
Adelaide Project and Tuscarora Project Option Agreement effective February 15,
2008 between Atna's wholly owned subsidiary Canyon Resources Corporation
("Canyon") and Golden Predator. As part of this Agreement, Golden Predator
assumed Canyon's obligations under the Adelaide Project and Tuscarora Project
Mineral Lease, Sublease and Agreement with subsidiaries of Newmont Gold. Under
these Agreement's, Atna may earn varying option payments through 2011 in
either cash or stock until Golden Predator has met its required spending
commitments on the project. Upon completion of required expenditures, Atna
shall retain a 1.5% Net Smelter Return royalty on both properties, subject to
certain limitations, and shall have the right to pre-production payments
capped at US$250,000.
    

    Adelaide
    
    On January 6, 2009 Golden Predator announced assay results on three core
drill holes and two reverse circulation (RC) drill holes at the Adelaide
Project, located in Southeastern Humboldt County, Nevada. The diamond drill
results were the first of a 13-hole diamond drilling program currently in
progress and which offset high grade intercepts in previous RC drilling. Core
hole GPAD03, targeting the North Margarite Vein, intersected 4.3 m of 15.42
gram per ton ("gm/t") (14 ft of 0.45 oz/t) gold, including 1.5 m of 31.7 gm/t
(5 ft of 0.93 oz/t) gold and 35 gm/t silver, from 85 m (280 ft) drill depth.
For full drill assay results please reference Golden Predator's January 6,
2009 press release at www.goldenpredator.com.
    

    Tuscarora
    
    Golden Predator announced on January 28, 2009 the initiation of drill
permitting for the Tuscarora Project, an early stage property located in Elko
County, NV. The objective is to test various targets generated from
compilation of historical data. Several historic drill intercepts encountered
by past operators contain greater than 1.0 oz/t gold, and merit additional
drilling to test for size potential of interest to the Company.  The Tuscarora
mining district is located approximately 38 miles northwest of Elko in the
Tuscarora Mountains in northeastern Nevada. It sits between the Carlin trend
22 miles to the south, Midas 30 miles to the west, and the Jerritt Canyon
district 12 miles to the northeast. The project covers approximately 8 square
miles lying proximal to the margin of the Mount Blitzen Caldera.
    

    Converse-Sand Creek Uranium Joint Ventures

    
    Effective February 2, 2009, Atna's subsidiary, Canyon Resources, entered
into an Agreement with New Horizon Uranium Corporation ("New Horizon") (TSXV:
NHU) to terminate the Converse Uranium Project Exploration, Development and
Mine Operating Agreement dated January 23, 2006.  New Horizon failed to meet
the spending and work requirements to earn a participating interest in the
project. As part of this Agreement, all of the shares of Horizon Wyoming
Uranium Inc. ("Horizon Wyoming") have been transferred to Canyon and Horizon
Wyoming shall become a wholly owned subsidiary. Horizon Wyoming holds
properties, reclamation bonds and permits related to the Sand Creek joint
venture with Uranium One Exploration USA Inc. a subsidiary of Uranium One Inc.
(TSX: UUU). In addition, New Horizon has also resigned as manager of the Sand
Creek joint venture. Horizon Wyoming shall be the new manager.  Ownership of
the Sand Creek Uranium Joint Venture now becomes 70% Atna, through Horizon
Wyoming, and 30% Uranium One Exploration USA Inc.  Atna will work with Uranium
One to determine the future program for this project.
    

    
    The Sand Creek uranium joint venture area of interest is located to the
south and east of Douglas Wyoming and was identified by Canyon and its former
joint venture partners during an aggressive uranium exploration effort in the
early 1980's. Drilling during 1981 and 1982 in the program area consisted of
88 drill holes for approximately 69,000 feet. In late 2006, a drill program
began in the western portion of the Sand Creek JV area and 14 holes were
completed totaling 10,395 feet, which clearly demonstrated the presence of
"roll front" style uranium mineralization. A follow up drill program
consisting of approximately 16 drill holes totaling 11,700 feet was completed
in mid-2007 and the favorable results were announced in a press release in
August 2007. Three of the 16 holes intercepted significant grades. The
drilling program consisted primarily of wide-spaced, reconnaissance style
drilling with drill hole spacing of 500 to 1,000 feet. Uranium mineralization
in the area is hosted in the Chadron Formation, which is composed of
sandstones, conglomerates, and red to green siltstones and claystones. The
sandstones are lenticular in nature and average from 5 to 20 feet in thickness
and occasionally range up to 45-feet thick.
