DRILL RESULTS FROM THE NORTHWEST ZONE AND BISHA HANGINGWALL COPPER ZONE, ERITREA

Nevsun Resources Ltd. (NSU-TSX and AMEX) (“The Company”) is very pleased to announce assay results from the recent drilling program on the Northwest Zone massive sulphide deposit as well as results of trenching and drilling of the Hangingwall Copper Zone of the Bisha deposit.

Highlights include:
NW Zone
Hole NW-023 averaged 7.08% Zn over 22.0 meters and 4.78% Zn over 10.5 meters
Hole NW-025 averaged 6.76% Zn over 6.15 meters
Hole NW averaged 5.59% Zn over 11.2 meters

Bisha Hangingwall Zone
Hole B-369 averaged 2.11% Cu over 19.6 meters
Hole B-370 averaged 2.64% Cu over 12.0 meters

NW Zone

Initial drilling in 2003 at the Northwest Zone identified low grade massive sulphides but Holes NW-008 and NW015 (press release dated 17 August 2005) intersected significant widths of sphalerite enriched massive sulphides with Hole NW-008 intersecting 22.1 meters averaging 1.42% Cu and 4.67% Zn.

During the Q1 2006 Bisha drill program 4 additional holes were targeted to bracket the previous zinc rich intersections. They returned sphalerite rich massive sulphide mineralization. It is now interpreted that this is a separate massive sulphide lense from the main lower grade Northwest Zone massive sulphide body. The main Northwest Zone is now interpreted to be striking off to the southwest.

The Northwest Zone represents significant massive sulphide bodies that will provide supplemental feed to the proposed Bisha processing facility.

Significant intersections include:

The location of holes drilled to date is shown in Figure 1. A significant amount of drilling will be required to determine the configuration and economic viability of this new massive sulphide body. 

As only one hole was drilled on each section calculating a true width of the sulphide bodies is not possible. It is estimated that the true width of the mineralization encountered in Holes NW-008 and NW-015 is in the order of 20 meters.

Bisha Hangingwall Copper Zone

As has been previously reported, there is a zone of relatively low grade near surface copper mineralization in the hangingwall, immediately west of the high grade Bisha massive sulphide deposit (see Figure 2). Drilling and mechanical trenching was carried out earlier this year to more fully define this zone. Past drill results had intersected up to 56.5 meters averaging 0.81% Cu in Hole B-335 and 0.76% Cu over 31.5 meters in Hole B-109.

Recent drilling 100 meters to the north of the holes mentioned above intersected 19.6 meters averaging 2.11% Cu in Hole B-369. Drilling 100 meters to the south (1715700) Hole B-370 intersected 12.0 meters assaying 2.64% Cu while an intersection (Hole B-371) 200 meters to the south (1715600) encountered 10.9 meters averaging 0.75% Cu.

Mechanical trenching over the latter drill intersection on line 1715600 encountered 86.0 meters averaging 0.55% Cu and 0.69 g/t In at a depth of 3.0 meters. A trench over the mineralized zone on line 1715700 encountered 1.4% Cu and 3.1 g/t In over 24.0 meters.  This may be a separate zone from that encountered in Hole B-370.

The Hangingwall Copper Zone will also add significant supplemental feed to the proposed Bisha processing facility.

Indium is known to be associated with the sulphide mineralization at Bisha and could conceivably be recovered as a byproduct in the metallurgical recovery process.

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