BISHA MAIN – 128 M OF MASSIVE SULPHIDES INCLUDING  12.74% ZN OVER 83.9 METERS

April 18, 2005

Nevsun Resources Ltd, is very pleased to announce the results from Hole B-329 drilled on the Bisha Main deposit that intersected massive sulphides an outstanding 8.4% Zn over 128.4 meters. Included in the intersection were 0.66 g/t Au, 49.1 g/t Ag, 0.96% Cu and 0.32% Pb. The sulphide mineralization extended from down hole depths of 288.6 to 417.0 meters.

372.5	417.0	44.5	0.56	22.9	1.05	0.30	0.30

The intersection is comprised of two distinct zones of massive sulphides. An upper sphalerite rich zone that assays 0.72 g/t Au, 62.0 g/t Ag, 0.92% Cu, 0.49% Pb and 12.74% Zn over 83.9 meters followed by a copper enriched zone that returned 0.56 g/t Au, 22.9 g/t Ag, 1.05% Cu, 0.30% Pb and 0.30% Zn over 44.5 meters. Zinc assays are cut to 30%.

The hole was drilled on section 1715550 and represents one of the deepest intersections on the deposit to date (a vertical depth of 385 meters). Hole B-212 drilled in 2004 intersected 0.61 g/t Au, 56.9 g/t Ag, 0.62% Cu, 0.43% Pb and 8.45% Zn over 58.5 meters a further 75 meters to the south, at a similar depth.

The intersection in Hole B-329 represents the style of mineralization that makes Bisha a world class VMS deposit. It is a depth extension to the mineralization on section 1715550 and extends the deepest intersection of the resource northwards. This hole provides further positive indication of the continued growth potential of the Bisha Main massive sulphide deposit to depth.

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