Nevsun Resources Ltd.: Initial Assay Results From
Nevsun's 2005 Drill Program at the Bisha Main
Gold/Copper/Zinc VMS Deposit, Eritrea

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 29, 2005) - Nevsun
Resources Ltd (TSX:NSU)(AMEX:NSU) is very pleased to announce the
initial assay results from the 2005 drilling program on its Bisha Main
gold/copper/zinc VMS deposit located in western Eritrea. These results
constitute the start of the Nevsun's 2005 drill program results from
Eritrea.

The vast majority of the holes listed below were drilled to relatively
shallow depths in order to extend known mineralized zones that had not
been fully defined by previous drilling. Oxide and supergene copper
mineralization were the primary targets. These results provide some
growth potential to the Bisha Main oxide and supergene resources. They
will allow the open pit mining profile for the Bisha feasibility study
to be more fully delineated.



Highlights include:
Oxide Zone
Hole B-314 intersected 12.43g/t Au over 15.35 meters
Hole B-316 intersected 7.75g/t Au over 23.25 meters
Hole B-318 intersected 18.06g/t Au over 27.33 meters
Hole B-320 intersected 17.04 g/t Au and 367.9g/t Ag over 15.0 meters


Supergene

Hole B-310 targeted primary massive sulphides towards the south end of
the deposit. Two distinct zones of massive sulphides were intersected,
one being zinc rich while the other was more copper rich. The lower zone
may represent a lower footwall lens that has not been previously
identified. Future drilling will provide an opportunity to test this
area where the deposit is interpreted to remain open to depth and along
strike.

Holes B-322, B-325 and B-328 were testing the boundaries of the deposit
and did not intersect any significant mineralization, however, they did
contribute to a better understanding of the overall configuration of the
deposit Hole B-328 was drilled to a depth of 430 meters. It has been
lined so that it can be surveyed with downhole EM when the geophysical
crew arrives at Bisha in early April.

Hole B-323 intersected a sulphide sand layer at the interface between
the oxide zone and the massive sulphide zone. It assayed 98.22g/t Au
over 4.0 meters.

It should be noted that in addition to the oxide intercept shown in the
table above hole B-321 also intersected 4.5 meters of copper
mineralization that assayed 0.90% Cu relatively close to the surface in
the oxide layer. The copper is in the form of malachite and is seen
relatively often in the near surface environment but has not been
modeled.

The overall results of the infill program have been very positive with
the average grade of the drill intersections being somewhat higher than
the average grades estimated in the October 2004 Bisha resource model.
Further drilling is in progress at the Bisha Main deposit testing the
opportunities to depth for the primary sulphides.

Nevsun's current 2005 drill program includes Bisha concession VMS
targets as well as epithermal gold targets at the adjoining Okreb
concession. The Bisha concession VMS targets include Bisha Main (as
reported in the current press release), the NW Zone (located 1.5km to
the north west of Bisha Main) and the new Harena Zone (located 9km to
the south west of Bisha Main). Assay results from the NW Zone and Harena
will be reported separately. Ground mapping, geochemical surveys and
mechanical trenching are currently in progress at Okreb.

Bill Nielsen, Vice-President of Exploration for Nevsun, a qualified
person under National Instrument 43-101, supervised and directed all
work associated with the drilling program.

Sample preparation and analysis were conducted at ALS Chemex of
Vancouver, Canada.

Forward Looking Statements: The above contains forward looking
statements that are subject to a number of known and unknown risks,
uncertainties and other factors that may cause actual results to differ
materially from those anticipated in our forward looking statements.
Factors that could cause such differences include: changes in world gold
markets, equity markets, costs and supply of materials relevant to the
mining industry, change in government and changes to regulations
affecting the mining industry. Although we believe the expectations
reflected in our forward looking statements are reasonable, results may
vary, and we cannot guarantee future results, levels of activity,
performance or achievements.
