MDN Inc. ("MDN")(TSX:MDN) is pleased to announce that it has entered into an
agreement with SOQUEM Inc. for the MCGold project in Chibougamau also known as
MOP II . The agreement grants MDN the option to acquire a 50% interest in the
project in consideration of a payment schedule and exploration expenses of up to
$5.25 million over five years. Work commitments are $350,000 for the first year
and $500,000 for the second year. MDN will become the operator once the project
reaches the feasibility study stage. 


"This advanced exploration project with a 43-101 resource is a good fit with our
strategy of acquiring and developing gold resources with potential for increased
tonnage and grade. Our goal is to define a resource with a potential gold
content of over one million ounces," stated Serge Bureau, President and Chief
Executive Officer of MDN. 


In 2006, SOQUEM retained Scott Wilson Roscoe Postle Associates Inc. to carry out
a 43-101-compliant estimate of the inferred mineral resource. The estimate was
calculated at a gold price of US $500/ounce and a cut-off grade of 1.0 g/t Au. 




Inferred Category       Tonnes    Au g/t   Ounces Au      Cu %
Main Zone            3,216,000      1.61     166,200      0.04
North Zone              24,000      1.32       1,000      0.12
Total                3,240,000      1.61     167,200      0.04



"We feel that this project has potential for porphyry-type Au-Cu deposits, which
means that it should be developed based on a high-tonnage/low-grade deposit
model, where cut-off grade selection is important. With this type of deposit and
a gold price currently above US $1,000 per ounce compared to the US $500 per
ounce used for the 2006 estimate, the cut-off grade chosen will have a huge
impact on tonnage," noted Marc Boisvert, Vice President, Exploration of MDN. 


Deposit History

Since 1957, a number of drilling programs have been carried out by various
companies, for an approximate total of 36,000 metres of surface drilling, 1,400
metres of underground drilling and 1,000 metres of underground development. The
previous work aimed mostly at exploring for high-grade vein occurrences, not for
disseminated-type mineralization. Metallurgical testing by SGS Lakefield
Research Ltd. in 2005 returned positive results, showing 85% to 95% gold
recovery. 


Prior to SOQUEM's involvement, only 48% of the drill cores were sampled (13,537
m of the 27,924 m drilled), being only the sections with a high sulphide
content. In 2000, SOQUEM located the core from six earlier holes that had
intersected the mineralized zone, and was thus able to sample the totality of
the mineralization, including sections with low sulphide content. Three of the
six holes returned average grades that were higher than the previous results. 


The deposit mineralization is associated with a large envelope of disseminated
pyrite in the order of 200 m wide by 800 m long, and remains open at depth and
along strike. The gold mineralization is hosted in a quartz-feldspath porphyry
intrusive, and also occurs in the rocks immediately adjacent to the intrusive.
