Nevsun Drills 88.5m of 11.8% Zinc at Bisha Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 3, 2011) - Nevsun Resources Ltd. (TSX:NSU)(NYSE Amex:NSU) is pleased to report assays from the 41 infill diamond drill holes at the Bisha Main deposit.

Highlights

• High-grade zinc with copper below current Bisha pit design
• Confirmation of mineralization grades and widths at depth

Select High Grade Results Include:

• Hole #B-433 – 88.50m of 11.84% Zn & 0.76% Cu from 268.0m-356.5m
• Hole #B-459 – 94.65m of 8.29% Zn & 0.84% Cu from 308.5m-403.15m
• Hole #B-461 – 85.90m of 10.71% Zn & 0.86% Cu from 275.1m-361.0m
• Hole #B-427 – 103.80m of 4.98% Zn & 1.13 % Cu from 234.0m-363.0m
• Hole #B-434 – 99.60m of 5.78% Zn & 1.27% Cu from 294.4m-394.0m

The objective of this program was to infill drill the inferred resource portion of the Bisha Main deposit to convert those resources to an indicated resource category. The results were positive, and have confirmed the grade and continuity of the Bisha primary zone below the current pit shell design. The resulting resource and reserve restatement is expected in Q1 2012.

Cliff Davis, CEO commented, "Bisha is a world class VMS deposit that we see evolving into a world class VMS mining camp. The high-grade zinc and copper intercepts released today are part of an ongoing program to grow organically through drilling known mineralization in and around the Bisha operation."

The 16,000m of drilling took place May through July 2011. Detailed results are in the attached schedule together with a map of the hole locations.

Note. True thickness is estimated at approximately 85% of the drill intervals reported in the table.

Hole B-424 showed no significant mineralization.

Darin Wasylik, Senior Geologist for Nevsun, a qualified person under National Instrument 43-101, supervised and directed all work associated with the drilling program.

Sample preparation and analysis were conducted at ALS Chemex of Vancouver, Canada.

Forward Looking Statements: The above contains statements regarding positive drill results, and indications that the Bisha resources are likely more extensive than previously disclosed. Although we believe the expectations reflected in our forward looking statements are reasonable, results may vary, and we cannot guarantee future results, levels of activity, performance or achievements.
