VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/11/12 -- Nevsun Resources Ltd. (TSX: NSU)(NYSE Amex: NSU) -

Q1 2012 OPERATING HIGHLIGHTS

--  Mined 358,000 tonnes of ore at 4.07 g/t gold
--  Produced 82,000 ounces of gold
--  Maintain 2012 guidance of 190,000 to 210,000 ounces of gold production

Nevsun Resources Ltd. is pleased to announce strong production results of 82,000 ounces of gold for the quarter ending March 31, 2012. Gold production in the quarter was above expectations due to several factors, including a drawdown of gold-in-circuit in the processing plant in preparation for a mill reline and higher than anticipated grades in portions of the high grade stockpile. We reiterate our full year 2012 production guidance of 190,000 to 210,000 ounces of gold production.

A summary of the Company's first quarter operating results are as follows:

The mine performed well in the quarter, producing expected total tonnage and gold head grade. The costs associated with the removal of copper phase prestrip are deferred for accounting purposes.

The reduction in mined head grade for Q1 2012 compared to Q1 2011 is according to plan and fits with the Company's guidance on 2012 production. Q1 2012 plant tonnage was lower than the same period in the prior year due mostly to changing ore characteristics and to lower plant availability. The reduced milling was offset by higher than budgeted gold grades for the quarter. Gold recoveries in Q1 2012 decreased compared to the same period in 2011 due to changing ore characteristics. The lower recovery rate is expected to continue throughout 2012.

Full financial results will be released in mid-May 2012.
