News Release: Nevsun Resources Ltd.: High Grade Base Metals Within Massive Sulphides Zone Confirmed to Vertical Depths of 300 Meters at Bisha Project, Eritrea
Nevsun Resources Ltd. (TSX:NSU) is pleased to announce the assay results from an additional 9 diamond drill holes as part of the 30,000 meter 2004 program. The results continue to 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. Plans to drill to vertical depths of 400 meters on one section in the heart of the primary massive sulphide zone are being finalized.
HIGHLIGHTS: High-grade mineralization extends depth to 300 vertical meters. Some of the high grade intercepts include Hole B-164 with 74.65 meters true width grading 9.7% Zn, 1.15% Cu, 72 g/t Ag and 0.77 g/t Au, Hole B-163 with 25 meters grading 9.76% Zn, 0.92% Cu, 88.76 g/t Ag and 0.71 g/t Au, Hole B-162 with 41.75 meters grading 9.60% Zn, 1.49% Cu, 85.35 g/t Ag and 0.98 g/t Au, Hole B-161 with 26 meters grading 10.71%Zn, 0.72% Cu, 52.21 g/t Ag and 0.70 g/t Au and Hole B-160 with 25.50 meters grading 13.20% Zn, 1.36% Cu, 109.44 g/t Ag and 0.83 g/t Au.
To date, in 2004, 52 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 60-75 meters being attained. The gold bearing oxide zone was not targeted in this stage of the program.
Assay results from the 9 diamond drill holes at the Bisha Main Zone are listed below by mineral zones: O-Oxide, S-Supergene sulphides, Str-Stringers, P-Primary sulphides.

Assays on additional holes drilled will be released as available.
The reverse circulation drill has arrived in the country and is being mobilized to the project site for immediate start up on defining the oxide and supergene zones especially in the northern part of the Main Zone. The Company is on schedule to have a third party calculate a resource statement at the end of the second quarter of this year.
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.
