MAWSON FILES ONE OF FINLAND'S LARGEST CLAIM APPLICATIONS AT ROMPAS

VANCOUVER, May 3 /CNW/ --
VANCOUVER, May 3 /CNW/ - Mawson Resources Limited ('Mawson') TSX-MAW; Frankfurt-MRY; OTC-MWSNF.PK.  Mr. Michael Hudson, President & CEO, announces the Company has filed
684 claims applications for 60,897 hectares around the
Rompas-Rumavuoma-Mustamaa gold-uranium projects in Northern Finland. 
These applications replace the Company's one year old claim
reservations and represent one of the largest contiguous claim
applications made in Finland's history which secures Mawson's title
over a 30km mineralized trend.  In combination with Mawson's existing
claim applications that cover the main 6km gold-uranium mineralized
trend at Rompas, Mawson now holds a total of 833 claim applications for
75,340 hectares at the Rompas Project.

'Besides the outstanding bonanza gold and uranium exploration results
reported by the Company on Feb 22, 2011 from the first year of exploration along the 6km long trend at Rompas,
Mawson has now defined a new and large gold-uranium mineralized camp,
extending over a strike extent of 30km.  The prospectivity of the area
is reflected in the Company applying for one of Finland's largest
contiguous claim applications.  We look forward to putting a large
field team back on the ground later this month.' said Mr Hudson. 

Rompas is a new gold-uranium discovery with bonanza grades within a sampling
footprint of 6.0km strike and 200-250m width.  During 2010 Mawson
discovered 171 grab samples averaged 1,127.9 g/t gold and 3.6% uranium
and ranged from 0.1 g/t to 22,723 g/t gold and 0% to 47.9% uranium and
80 channel samples which averaged 0.59m @ 203.66 g/t gold and 0.73%
uranium. Channel samples are considered representative of the in-situ
mineralization sampled and channel widths quoted approximate the true
width of mineralization, while grab samples are selective by nature and
are unlikely to represent average grades on the property.  A detailed
map showing the location and distribution of channel and grab samples
can be downloaded from the Company's website at: http://www.mawsonresources.com/i/maps/Rompas_PLANFEB22.pdf.

At Rumavuoma, a gold-uranium mineralized trend is located approximately 3km east of
the 6km long Rompas trend.  Rumavuoma is secured by 13 claim
applications for 1,292 hectares.  Nine historic samples taken by Areva
NC within an area of 3.5 kilometres by 400 metres assayed from 0.1g/t
to 1.8g/t gold and averaged 0.3g/t gold and from 5ppm to 3860 ppm
(0.39%) uranium and averaged 517ppm uranium.

The Mustamaa project is located approximately 30km south and along strike of the
Rompas mineralized trend.  Uranium at Mustamaa is locally hosted by a
phosphatic breccia unit. The breccia is contained within greater than
500 metre long and up to 40 metre wide apatite bearing dolomite
horizon. Better drill intersections include: R13: 55.4m @ 0.03% U(3)O(8 )from 104m, including 4.1m @ 0.08% U(3)O(8 )from 120m and R10: 18.1m @ 0.03% U(3)O(8 )from 65m, including 8.4m @ 0.04% U(3)O(8 )from 73m.  Additionally at Mustamaa, a glacial boulder sampled by Mawson
and located approxamitely 500m west of the drilled breccia unit assayed
0.5g/t gold and 165ppm uranium.  This boulder is not sourced from the
same breccias horizon suggesting the potential for further gold
mineralization to be discovered between Rompas, Rumavuoma and Mustamaa.

Mawson has planned an intensive surface exploration program over the
entire area starting in late May, 2011.  The company has budgeted
C$750,000 for the next 5 months at Rompas and field crews will be
mobilized in the 3(rd) week of May due to an unusually warmer start to summer.  The shallow
drill program previously reported by the company on March 30 has been completed earlier than expected due to the early winter
breakup.  In total 28 drillholes for 155.65m were drilled along two
traverses to the north of the 6km mineralized trend at Rompas.  Further
information will be released as it comes to hand.

Under Finnish legislation, prospecting work (non disturbing exploration)
is allowable on a claim application; however disturbing exploration
such as drilling and trenching will be permitted on granting of
exploration claims.
