MDN/Eritrean Exploration Results

MONTREAL, QUEBEC--(CCNMatthews - March 17, 2005) - MDN NORTHERN MINING
(MINIERES du NORD - "MDN")(TSX:MDN) is pleased to report results from
its Eritrean exploration programs in 2004. As previously announced,
Eritrean Minerals Corporation ("EMC"), the Company's 75% owned
subsidiary, has been invited to restart its operations in Eritrea by the
Ministry of Energy and Mines and hereby confirms that it is recommencing
exploration in Eritrea.

MDN Northern Mining holds three groups of Exploration Licences in
Eritrea: Harab Suit, Matite and Seroa. During 2004 exploration programs
were conducted in Harab Suit and Matite.

The Harab Suit exploration program in 2004 focussed on surface sampling
of two of the parallel shear zones that are exposed in the area striking
in a North-North-East direction approximately one kilometre apart, and
cutting a sequence of metavolcanic sediments and quartz diorite
intrusives. One shear zone has been traced over an intermittent outcrop
length of 9 km and hosts the abandoned Tamanti gold mine, which was
operated in the late 1930s. The sampling method was based on traverses
of, as far as possible contiguous, surface channels cut with diamond
impregnated saw blades, operated by hand-held machines. This sampling
method proved to be highly effective in providing rock samples for assay
from two-metre long channels approximately 10 cm wide and 5-10 cm deep,
comparable in dimensions to typical diamond drill core. A total of 1002
such samples were taken.

At Harab Suit, the assay results of this program indicated three areas
with significant results, which are considered to merit further work.
One such area was the old Tamanti gold mine sector itself, where surface
quartz vein sample values ranged up to 6.34 g/t. The other two areas are
located approximately two and four kilometres to the south-south-west in
the Harab Suit Central sector, where apparently the same shear zone is
exposed in occasional outcrops in the alluvial plain of the Barka river.
This latter area included one traverse of 15 successive channel samples
representing approximately 30 sampled metres, in about 50 m across
strike, assaying an average of 2.09 g/t Au, with highest values (twice)
of 6.25 g/t Au over 2 m. Anomalous assay results in a less deformed
volcanic environment delineated a further area of interest, showing
values of 1.14 g/t gold, 0.3% copper, 13.7 g/t silver and, separately
0.05% lead.

A similar but smaller scale program was undertaken at the Matite licence
area, where a small and isolated outcrop of a mineralised breccia
discovered by EMC was investigated with identical, but one-metre,
channel samples. A total of 20 samples were collected covering an
outcrop area of approximately 20 m2. The assay results average 4.5 g/t
Au with the highest reported grade of 42.55 g/t Au. Further
investigation will have to await the possible availability of a portable
drill rig, due to the steep local topography.

The rock samples were prepared in Eritrea and assayed in Australia by
Genalysis Laboratory. These programs were conducted under the direction
of Dr Tim Williams MIMM C.Eng, a Qualified Person in terms of NI 43-101.

Carlos Bertoni, Northern Mining's CEO stated: "We have been very
encouraged with the results of our work in Eritrea. The country remains
one of the most prospective regions of Africa with the least amount of
modern exploration, a place where one still can walk over mineralized
outcrop that nobody has ever sampled. We are happy to be able to
continue our exploration effort and remain confident that significant
mineral deposits will be discovered. We are immediately launching
further exploration programs at the Harab Suit and Seroa areas and
planning to expand our project portfolio in the country."

NORTHERN MINING is a Montreal-based Canadian exploration company that
holds a 30% interest in the Tulawaka gold mine and a majority interest
in 20 licences in the vicinity of the mine, a majority interest in three
properties in Eritrea, and other gold and base metal exploration
interests in Quebec, Canada.
