Nevsun Reports Final High Grade Infill Drill Results at Timok Upper Zone

VANCOUVER, July 19, 2017 /CNW/ - Nevsun Resources Ltd. (TSX:NSU) (NYSE MKT:NSU) ("Nevsun" or the "Company") is pleased to announce final assay results from the recently completed infill drilling of the Upper Zone at the Company's Timok copper-gold project ("Timok Project") in Serbia. 

HIGHLIGHTS

• Drilling confirms continuity and the high-grade nature of the Upper Zone
• New massive and semi-massive sulphide intersections include:
• • 16.94% Cu and 6.97g/t Au over 25.5m, within 4.46% Cu and 2.38g/t Au over 280.0m in TC160146B
  • 15.86% Cu and 7.69g/t Au over 27.0m, within 5.18% Cu and 2.28g/t Au over 274.5m in TC170157
  • 20.57% Cu and 9.17g/t Au over 49.5m, within 6.77% Cu and 3.67g/t Au over 265.5m in TC160147
  • 15.63% Cu and 12.28g/t Au over 19.5m, within 5.37% Cu and 4.94g/t Au over 177.0m in TC160142
• Exploration drilling for additional Upper Zone type deposits underway

Nevsun CEO, Peter Kukielski, commented, "The high-grade assays reported today are the final holes from the infill drill program for the Timok Upper Zone.  This drilling is enabling development of improved geological and geotechnical models and we expect an upgrade to a high percentage of the resources. We are also excited to have exploration for additional Upper Zone type deposits underway.  At the Bor operation, just five kilometres away, there were in excess of twenty separate high sulphidation epithermal "upper zone" type deposits, we believe the possibility of finding additional deposits should be high."

Detailed drill results, sections and a plan map of drill hole locations are attached to this news release.  Holes are designed to intersect the high sulphidation mineralization at 80 to 95% of true width.

Timok Copper-Gold Project

The Timok Project is located in eastern Serbia near the Bor mining and smelting complex. The Timok Project is focussed on the Cukaru Peki ("Timok") deposit which includes the high grade Upper Zone (characterized by massive and semi-massive sulphide mineralization) and the Lower Zone (characterized by porphyry-style mineralization).

Timok Upper Zone

The high sulphidation epithermal mineralization (HSE) in the Upper Zone comprises massive sulphide, semi-massive and also vein, stockwork, dissemination and hydrothermal breccia matrix sulphide hosted by strongly altered andesite. The HSE mineralization forms a single coherent zone at depths ranging from 400 to over 800m below surface. Pyrite is the dominant sulphide mineral and covellite the principal copper mineral with lesser enargite, bornite and chalcocite occurring in veins, hydrothermal breccias, disseminations and replacement. Gold correlates with the copper sulphides preferentially occurring within pyrite bordering the copper sulphides.

Quality Assurance                                                                                 

Drill core samples were collected in accordance with protocols that are compatible with accepted industry procedures and best practice. The Company conducts its own analysis of QAQC generated by the systematic inclusion of certified reference materials, blank samples and duplicate samples. The analytical results from the quality control samples have been evaluated and have been demonstrated to conform to best practice standards.
