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.

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.
