MAWSON LAUNCHES SUMMER WORK AT THE ROMPAS GOLD DISCOVERY IN FINLAND

VANCOUVER, June 30, 2011 /CNW/ --
Mineralized footprint expanded in all directions

VANCOUVER, June 30, 2011 /CNW/ - Mawson Resources Limited ('Mawson') (TSX - MAW); (Frankfurt - MRY).  Mr. Michael Hudson, President & CEO, outlines the summer work program
at the Rompas Au-U discovery in Finland where the Company has budgeted
a C$750,000 program for this summer. Initial field results have
expanded the mineralized area in all directions.  Mr. Hudson also
reports on the results of the recently completed stratigraphic drilling
completed north of Rompas.

The second summer of work at Rompas will move from a prospecting
dominated phase to a program focused on understanding the detailed
controls on mineralization over the 6km strike length to define the
highest priority drill targets.  The Rompas project area is secured by
claim applications and drilling and trenching will be permitted on
granting of exploration claims.  An experienced team of fifteen
geologists and support staff is currently onsite and will work until
October to achieve the program objectives.

Work commenced 4 weeks ago and initial radiometric surface spectrometer
surveying has been successful in extending the known mineralized
footprint approximately 50m to the east, as well as 100m north, of
South Rompas.  In addition, a new and continuous 10-15m wide and 100m
long radiometric high has been discovered in the northwestern zone of
North Rompas. Approximately 40 new mineralized sites have been
discovered, stripped of moss and/or soil cover (Photo 1 - http://files.newswire.ca/748/mawsonphoto1.pdf) and channel sampling has commenced in these new areas.  Rock samples
have been submitted to the laboratory for assay and will be released
when available.

The exploration program over the discovery trend will include:

    --  Detailed mapping and prospecting over a 6km trend, with the aim
        to map and refine the understanding of the key structural,
        geological and alteration signatures associated with gold and
        uranium mineralization.  Further mapping will be completed at a
        larger scale over the 30km mineralized trend known to host the
        Rumavuoma and Mustamaa projects areas.

    --  A bedrock sampling program over an area of 8km by 500m with the
        aim to develop a firmer understanding of continuity of
        mineralization.  Sampling will consist of representative
        diamond saw-cut channels as well as pits and short trenches dug
        down to bedrock over areas with higher radiation.

    --  Prospect and regional-scale geochemical sampling of soils and
        organic matter, to better define extent of the mineralized
        trend, especially undercover.

    --  Five line-km of induced polarization geophysics over the
        mineralized sequence to characterize the chargeability and
        resistivity responses of the mineralized host and each distinct
        lithological trend.

    --  A research based project to determine origins and timing of
        gold and uranium mineralization and associated alteration.

Mr Hudson states, 'A substantial exploration program at Rompas is
warranted after the great success of the first year of exploration on
the property in 2010.  Field work this summer has already been
successful in extending the footprint of the mineralized area. 
Although hundreds of sites with high grade gold and uranium have been
discovered within an area exceeding 6km by 200m, much remains to be
learnt from this highly prospective area and we look forward to
delivering a steady and exciting news flow over the next 5 months from
the Rompas project.  The program will give the project the best chance
to be effectively drill tested when drill permits are granted by the
Finnish authorities'.

In other news, the shallow drill program completed in May 2011, of 28
drill holes for 155.65m drilled along two traverses 100m and 300m to
the north of the North Rompas mineralized zone.  The stratigraphic
drill program was designed to test for the presence of the host rock
sequence undercover to the north of Rompas, and not to drill beneath
known mineralized zones.  The program was successful in proving the
altered host sequence continues at least 350m undercover from the last
mineralized site at North Rompas (Figure 1 - http://files.newswire.ca/748/mawsonfig1.pdf).   Glacial cover averaged 3m to 5m over the area drilled while each
drill hole averaged 5.5m depth.
