Drilling expands near-surface uranium at Tasjo, Sweden



    VANCOUVER, June 11 /CNW/ - Mawson Resources Limited ("Mawson") TSXv -
MAW; Frankfurt - MRY. Michael Hudson, President & CEO, announces results from
additional drill holes completed by Mawson at its Kronotorpet uranium - rare
earth element (REE) prospect at the Company's Tasjo project in northwestern
Sweden.
    Results are available for a further 19 drill holes (KRODD06020 to
KRODD07038) of a 53-drill hole program. Results for these holes plus the first
19 holes released on March 19, 2007 are in the attached table.
    Uranium was targeted in a mineralized sedimentary horizon from surface to
approximately 40 metres vertical depth, across an area 1,100 metres in strike
and 250 metres wide. Drilling was performed on a grid of 25 or 50-metre
spacing, on sections separated by 100 metres. The aim of the program was to
collect sufficient samples to perform metallurgical test work, and to define
an initial CIM-compliant resource within the Kronotorpet area.
    Better results are included below with a full list of results presented
in the attached table 1.

    Tasjo is a sedimentary uranium deposit where uranium mineralization is
associated with concretions of carbonate-fluorapatite, which constitute up to
20% of the rock. Mass balance calculations indicate that the uranium grade of
the fluorapatite is 0.16%. Significant rare earth element mineralization is
contained within the uranium bearing sequence, again associated with the
carbonate-fluorapatite. Drilled intersections range from 0.03% to 0.12%
combined REE and averaged 0.09% combined REE. The dominant REE at Tasjo are
yttrium (Y), cerium (Ce), neodymium (Nd), europium (Eu) and ytterbium (Yb).
    Mawson controls a 40-km strike extent of the uranium-mineralized unit in
the Tasjo field. Based on 80 historic drill holes and the report, "Geological
Investigations in the Tasjo area in 1963 and 1964" (G. Armands, Swedish Atomic
Energy Company) it is estimated that 75 to 150 million tonnes exist at Tasjo,
with a grade range of 0.03% to 0.07% uranium oxide (U(3)O(8)), 0.11% to 0.24%
REE and 3.75% to 7.5% phosphate (P(2)O(5)). Total contained metal within the
field is estimated to be between 104 to 116 million pounds of U(3)O(8),
165,000 to 180,000 tonnes of REE and 5.63 million tonnes of P(2)O(5). This
exploration target estimate is based on the aforementioned report. The
potential quantity and grade is conceptual in nature, as there has not been
sufficient exploration to define the target at this time; and it is uncertain
that further exploration would result in the definition of a resource.
    The magnitude of the exploration target was confirmed in a recent
independent NI43-101 technical report by Andrew Browne of Geosynthesis Pty
Ltd, the current qualified person at the Jabiluka uranium project in
Australia, after a review of Swedish Geological Survey documentation, a field
visit and check analysis of core samples.
    Further information regarding the Tasjo project and the current drilling
program may be found at
http://www.mawsonresources.com/index.php?page=ProjectsTasjo. In addition,
after a test program, a ground EM survey commenced at the Tasjo project to map
accurately the near-surface host rock to uranium mineralization over a
20-kilometre strike length. Furthermore, a preferred metallurgical consulting
group has been identified with extensive uranium and REE processing
experience, with which terms of reference for metallurgical research are being
discussed.
    Mr. Hudson stated: "The new drill results from Tasjo continue to
demonstrate consistent at or near-surface uranium mineralization. The Company
continues to be encouraged by the regularity of grade, the strike extent and
the shallow depth of uranium mineralization. Drilling results from the final
third of the program will be released as they become available."
    Uranium was analyzed by the ME-MS81u technique by ALS Chemex Ltd's
laboratory in Vancouver, Canada, where duplicates, repeats, blanks and known
standards were inserted according to standard industry practice. The qualified
person for the Tasjo project, Mark Saxon, Director and Vice-President of
Exploration for Mawson, and a member of the Australasian Institute of Mining
and Metallurgy, has reviewed and verified the contents of this release.

    About the Company: Mawson Resources holds significant uranium resources
in the nuclear energy reliant countries of Spain, Sweden and Finland. As the
European Union reduces its reliance on carbon-based energy sources, Mawson is
well placed as the Company develops its exploration portfolio towards the
sustainable production of uranium in the shortest possible time frame.
