INITIAL ASSAY RESULTS FROM NEVSUN’S 2005 DRILL PROGRAM AT THE BISHA MAIN GOLD/COPPER/ZINC VMS DEPOSIT, ERITREA


March 29, 2005


Nevsun Resources Ltd 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:

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.
