Atna Reports Additional Pinson Drill Results



    GOLDEN, Colo., June 4 /CNW/ -- Atna Resources Ltd. ("Atna") - (TSX: ATN)
is pleased to report that Barrick Gold has delivered all assay results from
its recent drilling programs at the Pinson Mine Project, Humboldt County,
Nevada. The Pinson Mine Project is a Mining Joint Venture with Pinson Mining
Company ("PMC") a subsidiary of Barrick Gold, owning a 70 percent interest,
and Atna owning a 30 percent interest. PMC is the operator of the venture.

    "The Pinson project continues to host numerous high grade gold intercepts
on a number of structures all located in a relatively small area. We feel that
Pinson has a good potential for development due to its gold grade, location in
the heart of the northern Nevada gold belt and close proximity to existing
autoclave, roaster and mill complexes. PMC is evaluating the results of its
extensive drilling program and data review to determine the future program for
property. Between three and four months will be required to complete this
technical analysis that will be the basis for the future development of the
project," states James Hesketh, President & CEO.

    From mid 2007 through December 2008, Barrick completed 163 surface and
underground drill holes totaling 112,578 total feet of drilling (91,892 feet
from surface drill sites and 20,686 feet underground) as part of its earn-in
obligations. Total reverse circulation footage was 50,721 feet and core
footage totaled 61,857 feet. In addition, PMC completed an extensive review
and quality control analysis of historic drill information and data. PMC's
focus included both shallow drill targets to be evaluated for open pit mining
potential as well as high grade drill targets at depth for potential
underground development.

    The joint venture has agreed to a property budget that allows for
continued dewatering of the underground workings while the technical
evaluation is being completed. Atna's share of the current budget for the
remainder of 2009 is estimated to be $237,000.

    Drilling reported by Barrick included a significant number of infill
drill holes within the Ogee, the CX-West, the Range Front (and hanging wall
splays), and Mag Pit mineral zones. This new information, along with the
existing drilling data developed by Atna and prior operators, will serve as
the basis for PMC's ongoing evaluation of the project's potential. Highlights
of the drill results not previously reported are tabulated below.

    * Intercept lengths do not represent true widths of the mineralized zones.
    
    ** Many intercepts are carbonaceous and pyritic and may have refractory
characteristics.

    The vast majority of the surface drill holes were pre-collared with RC
drill rigs, cased, and finished by diamond drilling through the targeted zones
and underground drilling was principally diamond drilling.

    All sample preparation and assay results reported in this press release
were completed by American Assay Laboratories in Reno, Nevada, an independent
