NORTHERN MINING Explorations Ltd.: Exploration at
Tulawaka West Zone

MONTREAL, QUEBEC--(CCNMatthews - Feb. 28, 2005) - NORTHERN MINING
Explorations Ltd. (Explorations MINIERES du NORD - "MDN") (TSX:MDN) is
pleased to report that it has received a summary of drill hole assay
results from exploration being conducted by the Joint Venture
participants at the Tulawaka project in Tanzania.

These results are from a reverse circulation drilling program totalling
3000 metres conducted on the "West Zone" target, some 4 km to the west
of the East Zone pit currently under development. The project operator
is Pangea Minerals Limited, a wholly-owned subsidiary of Barrick Gold
Corporation. It has reported that intersections obtained from the West
Zone drilling programme include the following:

The objective of this drilling program was to test the boundaries of the
previously identified mineralisation. The drill holes TRC1373 and
TRC1374 were two holes drilled on the north eastern most line in the
programme and therefore follow up drilling will be planned to determine
the extent of this near surface anomaly. A resource estimation on the
West Zone at Tulawaka will be completed by the end of the first quarter
this year.

This work is being carried out and managed by Pangea/Barrick geologists,
and all samples were analysed at the SGS Laboratory in Tanzania.

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 adjacent licences in Tanzania, a majority interest in four
properties in Eritrea, and other gold and base metal exploration
interests in Quebec, Canada.
