Nevsun Drills 37.5m of 8.26% Copper Adjacent to Bisha Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 27, 2011) - Nevsun Resources Ltd. (TSX:NSU)(NYSE Amex:NSU) is pleased to report the assays from the final four diamond drill holes from the hanging wall copper phase one drilling at the Bisha Deposit. These four holes were delayed due to mining operations in the area.

Highlights

• Extension of Bisha Main Sulphide Lens
• Near surface copper mineralization adjacent to Bisha Main deposit
• Likely additional feed for Bisha supergene copper phase

Select High Grade Results Include:

• Hole B-464 – 37.5m at 8.26% Cu, from 31.5 meters to 69.0 meters
• Hole B-465 – 12.0m at 1.29% Cu, from 76.0 meters to 88.0 meters

Drill holes B-464 and B-465 intersected the same supergene sulphide lens that was intersected by drill hole B-395 and B-396 that were previously reported in the press release issued August 31, 2011. Drill hole spacing is approximately 50m x 50m. The sulphide lens appears to be an extension of the northwest lens of Bisha that was faulted off and is not included in currently disclosed resources.

Detailed results are in the following table together with a map of the hole locations.

Note: True thickness is estimated at approximately 90% of the drill intervals reported in the table.

Phase II drilling of the hanging wall copper zone, designed to further infill drill the zone as well as the newly identified lens is complete and assay results are expected later in Q4.

The Company also completed a 16,000 meter diamond drill program on the Bisha Main deposit below the existing planned pit. Final results of this drill program are expected soon with a second resource and reserve re-statement now targeted for Q1 2012. Nevsun had previously guided Q4 2011 but has pushed back the date due to additional drilling follow-up on the above and availability of third party engineers.

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.
