      Mawson Files One of Finland's Largest Claim Applications at
      Rompas

=======================================================================

Vancouver, Canada -- 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% U3O8 from 104m, including 4.1m @ 0.08% U3O8 from 120m and R10:
18.1m @ 0.03% U3O8 from 65m, including 8.4m @ 0.04% U3O8 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 3rd 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.

About Mawson Resources Ltd

the highly prospective Cordillera of Peru, with a focus on a new
gold-copper discovery at Alto Quemado.

With a strong cash position and a multi-jurisdiction European and South
American portfolio, Mawson is ideally positioned to enhance its status
as a leader in the uranium and gold industries.

Shares Outstanding: 51,645,753. Cash: approximately C$13 million.
