Nevsun Continues to Generate Free Cash Flow in Q2 2015

Nevsun Resources Ltd. (TSX:NSU)(NYSE MKT:NSU) (Nevsun or the Company) is pleased to report its financial and operating results for the three and six months ended June 30, 2015. Unless otherwise noted, with the exception of earnings per share and realized price and cost per pound figures, all financial results are in millions of US dollars.

Second quarter 2015 highlights

• Earned $0.05 per share
• Generated $58 million cash from operating activities
• Working capital of $499 million, including $452 million of cash
• Produced 32.4 million pounds of copper
• Continued lowest-quartile C1 cash costs1 of $0.97 per payable pound sold
• Paid quarterly dividend of $0.04 per share
• Continued zinc expansion project - on-time and on-budget
• Discovered a new VMS mineral deposit in the Bisha District
• Monetized stockpiled precious metals concentrate

Financial Review

(1) C1 cash cost per payable pound sold is a non-GAAP measure - see page 12 of the Q2 2015 MD&A for a discussion of non-GAAP measure.

Cliff Davis, CEO of Nevsun, commented, "Despite copper price declines and some planned and unplanned plant stoppages in Q2, we had another quarter of strong earnings and free cash flow generation. The sale of the precious metals concentrate and a focus on cost control made a significant contribution to our bottom line. We are pleased to report our overall cash balance increased during the quarter even with a weaker quarter of copper production and significant capital spending on the zinc expansion, which remains on-time and on-budget."

Operations Review

(1) During the three and six months ended June 30, 2015, 267,000 and 394,000 tonnes of primary ore were mined and stockpiled for future production.
(2) Q1 2014 included 4.5 million pounds or 2,000 tonnes of pre-commercial production. Receipts from pre-commercial production sales were credited against mineral property, plant and equipment, net of cost of sales.

Cliff Davis went on to say, "Due to the unplanned plant stoppages in 2015 we are revising our 2015 guidance to 140 to 150 million pounds for 2015. However, our cost outlook has significantly improved and we are pleased to report that we are maintaining our C1 cash costs per payable pound of copper guidance of $1.20 to $1.40 despite the lower production, ensuring another profitable year for our shareholders. For the longer term outlook, I am really pleased with the continued exploration success and that the zinc expansion remains firmly on track and on budget. We are maintaining maximum optionality for zinc offtake which remains 100% uncommitted. We expect further exploration results from Bisha regional drilling throughout 2015 and are increasingly optimistic the current commodity price environment will generate M&A opportunities."
