Nevsun Resources Ltd.: Bisha Royalty Buyout Increases Future Cash Flows

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/23/10 -- Nevsun Resources Ltd. (TSX:NSU)(NYSE Amex: NSU) is pleased to announce that it has bought out a third party royalty on its Bisha project in Eritrea. The removal of this royalty further increases Nevsun's stake in Bisha's future cash flows, resulting in an estimated net benefit of at least $0.20 per share. Nevsun paid Cdn$18,500,000 to acquire the 1.5% net smelter royalty on the project, previously held by an arm's length private company.

The Bisha project continues on time and on budget to advance towards plant commissioning in Q4 of this year. The Company anticipates reaching commercial production before the end of Q1 2011, at which time its annualized output should exceed 400,000 ounces of gold, plus 750,000 ounces of silver, at a cash operating cost of less than $250 per ounce of gold. More details on the Bisha project, including cash flow estimates under various metals price assumptions can be found on the Company's website.
