Atna Extends Gold Mineralization at Cecil R Project



    GOLDEN, Colo., April 7 /CNW/ -- Atna Resources Ltd. ("Atna") - (TSX: ATN)
is pleased to announce that recently completed drilling at the Cecil R project
located four miles north of the Briggs Mine, in Inyo County, California, has
significantly extended the known zone of gold mineralization. The drilling
program included 8,070 feet of reverse circulation rotary drilling in 23 drill
holes designed to expand the known mineralized zone to the south and increase
drill hole density in the main area of gold mineralization. The program
successfully extended mineralization 700 feet to the south and defined the
western and eastern limits of the mineralization within the known mineral
horizon.
    

    
    Gold mineralization at Cecil R has been intercepted in a total of 94
drill holes totaling 21,956 feet distributed over an area 2,000 feet
(north-south) by 1,000-1,200 feet (east-west). The mineralization is located
directly beneath Quaternary alluvial cover and is hosted along an iron
oxide-rich, gently dipping zone within strongly weathered
quartz-muscovite-feldspar gneiss and amphibolite. The zone's thickness is
variable, ranging in thickness from 10 feet to over 100 feet and occasionally
several subparallel zones are present. Within the principal zone of
mineralization there are 647 drill samples grading over 0.01 ounce per ton
gold, representing 3,214 lineal feet of drilling, which have an average grade
of 0.028 ounce per ton gold. This compares to the average grade of proven and
probable reserve at the nearby Briggs Mine of 0.021 ounce per ton gold.
    

    
    The Cecil R project is being evaluated as a satellite project to the
Briggs Mine where Atna will begin gold production in the second quarter of
2009.  The work completed in this program and the data from previous drilling
is being compiled and is anticipated to provide sufficient information to
allow the first NI 43-101 compliant resource calculation for the property to
be completed during the summer of 2009.
    

    
    Atna's President and CEO, James Hesketh, states, "We are encouraged by
these new assay results and expansion of the mineralized zone at Cecil R. The
Cecil R project may allow us to add additional years of operating life in the
Briggs Mine district should an economic reserve be developed at Cecil R. The
project should benefit from the close proximity of the Briggs Mine
infrastructure, management, and staff. Cecil R will require stand-alone
permitting under existing regulations in California which may be feasible due
to the favorable geometry of mineralization."

      need for and ability to obtain additional financing; the possibility
      that the Company may not be able to secure permitting and other
      governmental clearances necessary to carry out the Company's mine
      development plans at the Briggs Mine; the possibility that the Company
      may not be able to secure permitting and other governmental clearances
      necessary to carry out the Company's mine development plans at the
      Cecil R project; and the other risk factors discussed in greater
