VANCOUVER, June 28 /PRNewswire/ --

- Attention Business Editors

Mawson Resources Limited ("Mawson") TSXv - MAW; Frankfurt - MRY. Michael 
Hudson, President & CEO, reports that the Company is pleased to announce 
that the final permitting process at Don Benito uranium investigation 
permits has commenced. The Mining Authorities from the Spanish province of 
Badajoz ("Junta de Extremadura") have requested that Mawson make a 
"Guarantee Payment" for the definitive admission of the uranium 
investigation permits that cover the Don Benito uranium project. Payment of 
this guarantee by Mawson on June 27th 2007 to the Mining Authorities marks 
the final phase of the claim permitting process, and the Company is 
confident that the granting and demarcation of the Don Benito Investigation 
Permits (12684-D and 12686-D) shall be complete by year's end. The Don 
Benito uranium claims cover the La Haba open pit uranium mine which ceased 
operation in 1990, and the adjacent in-situ uranium resources. The mine and 
resource area are currently overlain by the 3,865 hectare La Haba State 
Mineral Reserve. Spanish Mining Law states that on lifting of a State 
Reserve, the mineral rights within the State Reserve, will fall directly to
the holder of the overlying granted permits. In addition to the definitive
admission of the uranium investigation permits, the La Haba Mineral Reserve
is currently in the process of being lifted by the National Authorities of
Spain.

Significant un-mined historic resources remain within the La Haba State
Reserve, including:

- 6.0 million lbs at 0.06% U3O8 at a 200ppm lower cut-off, - 3.0 million
lbs at 0.1% U3O8 at a 600ppm lower cut-off.

The resources were calculated using a computational inverse distance
method based on 3 metre horizontal benches and 40 metre square cells and is
roughly analogous to the CIM definitions "Measured" and "Indicated". The
depth of the resource extends from surface to 130 metres. The quoted
resources are based on the PhD Thesis, "Petrology and Geochemistry of the
Uranium Deposits of South East Badajoz" by Dr Javier Almarza Lopez of the
University of Seville dated March 1996. These data are historical in nature
and were compiled prior to the implementation of Canadian NI 43-101 reporting
standards. Mawson has not completed sufficient exploration to verify the
estimates and is not treating them as National Instrument compliant resources
or reserves verified by a qualified person and the historical estimate should
not be relied upon. The Company believes this historical resource and the
data used to compile the estimate - which represent the most recent estimates
and data available - are generally reliable and relevant. Mr Hudson states,
"We are extremely pleased that the final definitive admission of the Don
Benito permits has commenced. The project is unique in that significant
infrastructure is already in place including power, roads and 30 kilometers
of resource and reserve drilling. Considering the pace of granting, the
Company is now compiling all the past data with the aim to move to a NI
43-101 compliant resource by the December 2007. Concurrently, the Company
will undertake a scoping study aimed at determining the potential economic
scenario of reopening the Don Benito uranium. This study is slated for the
first quarter of 2008." The qualified person for the Mawson's Spanish uranium
projects, 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.
