Nevsun Continues to Intersect High Grade Mineralization at Harena

Nevsun Resources Ltd. (TSX:NSU) (NYSE MKT:NSU) (Nevsun or the Company) is pleased to announce new assay results from drilling at Harena which is part of the on-going 2015 Regional Exploration program at Bisha.

Highlights

• New drilling demonstrates continuity of Harena mineralization
• New select massive sulphide intersections at Harena include:
  • HX-069: 115.2 m @ 0.79% Cu, 4.95% Zn, 0.45 g/t Au, 14 g/t Ag, including 39.6 m @ 0.60% Cu, 10.21% Zn, 0.58 g/t Au, 19 g/t Ag
  • HX-071: 49.7 m @ 0.66% Cu, 7.94% Zn, 0.32g/t Au, 17g/t Ag, including 35.9 m @ 0.33% Cu, 10.20% Zn, 0.23g/t Au, 13g/t Ag
  • HX-068A: 38.0 m @ 0.86% Cu, 7.30% Zn, 0.35 g/t Au, 13 g/t Ag
• New stringer / semi-massive intersections at Harena include:
  • HX-070: 24.7 m @ 1.95% Cu, 1.25% Zn, 0.93 g/t Au, 86 g/t Ag, including 12.1 m @ 3.44% Cu, 0.44% Zn, 1.17 g/t Au, 128 g/t Ag
  • HX-066: 42.0 m @ 1.11% Cu, 0.93% Zn, 1.46 g/t Au, 55 g/t Ag, including 5.50 m @ 0.67% Cu, 0.33% Zn, 4.79 g/t Au, 141 g/t Ag
• Harena still open with geophysical modeling suggesting further expansion potential possible

Nevsun CEO Cliff Davis commented, 'Our drilling at Harena continues to produce excellent results. We are very encouraged by the higher zinc grades being encountered at depth in addition to the continuous copper-rich zone. Harena remains open at depth and there is still considerable potential along strike to the north and south. Drilling in 2015 has tightened our drill spacing to 100 metre centres down to a depth of 600 metres below surface. An updated mineral resource estimate is due out in early January 2016'.

Harena

Harena is located 10 kilometres south of the Bisha processing plant and drilling continues to expand the deposit along strike and at depth. Many of the results reported in today's update are part of an in-fill program designed to tighten the drill spacing at Harena down to a maximum of 100 metre centres.

Hole HX-069, intersected the thickest zone of massive sulphides yet encountered at Harena. Massive sulphides occur over a 115.2 metre interval which also includes three cross cutting mafic dikes. The upper part of the mineralization is particularly zinc-rich with a grade of 10.21% zinc over 39.6 metres. High zinc grades were also encountered in the massive sulphides intersected in holes HX-068A (8.62% Zn over 31.5 metres) and HX-071 (10.20% Zn over 35.9 metres).

The mineralization continues to display a consistent metal zonation pattern that consists of a sphalerite and pyrite, zinc-rich upper zone and a lower chalcopyrite and pyrite, copper-rich basal zone. Basal copper-rich zones were intersected in holes HX-066 (2.84% Cu over 9.0 metres), HX-068A (3.53% Cu over 6.5 metres), HX-069 (2.31% Cu over 24.2 metres), HX-070 (3.44% Cu over 12.1 metres) and HX-071 (1.61% Cu over 12.7 metres).

Significant extents of copper-rich stringer mineralization with elevated precious metals were intersected beneath the massive sulphides in holes HX-066 (1.11% Cu, 1.46 g/t Au, 55 g/t Ag over 42.0 metres including 2.84% Cu, 0.92 g/t Au, 59 g/t Ag over 9.0 metres and 0.39% Cu, 2.71 g/t Au, 86 g/t Ag over 11.0 metres) and HX-070 (1.95% Cu, 0.93 g/t Au, 86 g/t Ag over 24.7 metres including 3.44% Cu, 1.17 g/t Au, 128 g/t Ag over 12.1 metres).

Borehole Transient Electromagnetic (TEM) surveys continue to help guide the exploration effort. The zinc-rich mineralization is of moderate conductance and correlates with the geophysical plate models based on the responses in holes HX-067 and HX-055 (green plate 67 and blue plate 55-2). The copper-rich basal mineralization correlates with the high conductance geophysical plate 55-1 derived from the modeling of the response in hole HX-055. The modeling also suggests that mineralization is likely to continue down dip and down plunge.

Quality Assurance

A Quality Assurance/Quality Control program was part of the assaying program at Bisha. This program includes chain of custody protocols as well as systematic use of standards, duplicates and blank samples into the flow of samples produced by the sampling. All samples were prepared and analyzed at Bisha's on-site laboratory independently operated by SGS.

Drilling intercept lengths only are reported in the tables and text below.

Mr. Robert Foy P.Geo., BMSC's Exploration Manager, has been overseeing the drilling at Bisha and is a Qualified Person as defined by NI 43-101. Mr. Foy has reviewed the technical content of this press release and approved its dissemination.
