Nevsun Resources Ltd.: High Grade Base Metal Assays Show Strong Growth Potential With Massive Sulphides Zones Confirmed to Vertical Depths of 300 Meters at Bisha Project, Eritrea
Friday March 5, 1:40 pm ET
VANCOUVER, British Columbia--(BUSINESS WIRE)--March 5, 2004--Nevsun Resources Ltd. (TSX:NSU - News) is pleased to announce the assay results from the first 13 diamond drill holes of the 30,000 meter 2004 program and the final 5 drill holes (B-142 to B-146) completed at its Bisha Project in 2003. The results reflect a continuity of mineralization both along strike and to depth and demonstrate significant potential for a long term mine life from the primary sulphides of the Bisha Project, subsequent to the mining of the gold rich oxide layer at surface and the copper-rich supergene zone. It is becoming more apparent that a specific zonation of zinc rich and copper rich mineralization is present within the primary zone situated below the supergene copper horizon and the high-grade gold oxide cap. Plans are to drill to vertical depths of 400 meters during the current program once all assay results are received and initial interpretations have been completed as to the configuration of the mineralization with depth.

HIGHLIGHTS
High grade zinc mineralization continues to be intersected in the primary massive sulphide zone
Massive sulphides up to 50-60 meters true width intersected to depths of 300 meters vertical
Exploration drilling commenced on targets 2.0 km to the southwest of Bisha Main
Environmental baseline studies commenced
To date, in 2004, 34 diamond drill holes have been drilled in the southern part of the Bisha Main zone. Some of these holes have been drilled to vertical depths of 300 meters in an effort to determine the depth extent of the deposit. The zone remains strong at these depths with true widths of massive sulphides in the order of 50-60 meters being attained. Assay results from the deep holes are pending. The gold bearing oxide zone was not targeted in this stage of the program.
Assay results from the initial 13 diamond drill holes from the 2004 program at the Bisha Main Zone are listed below by mineral zones: O-Oxide, S-Supergene sulphides, Str-Stringers, P-Primary sulphides. .

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.
Nevsun implemented a QA/QC program, consisting of certified standards, for the drill program. The analytical methods used for gold and silver are fire assay with atomic absorption or gravimetric finish. Induced Coupled Plasma (ICP) is used for silver trace level values. The analytical methods used for the base metals are aqua-regia digestion and atomic absorption finish or ICP for trace level values. 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.
