Initial Assay Results
from the 2005 Drill Program at the NW Zone
Massive Sulphide Deposit, Eritrea
INITIAL ASSAY RESULTS FROM THE 2005 DRILL
PROGRAM AT THE NW
ZONE
MASSIVE SULPHIDE DEPOSIT,
ERITREA
April 18, 2005
Nevsun Resources Ltd wishes to announce
assay results from the initial 13 diamond
drill holes of the 2005 drill campaign it
has established at the Bisha concession NW
Zone volcanogenic massive sulphide deposit.
The NW Zone is located 1.5 kilometers to the
northwest of the Bisha Main deposit.
The Bisha volcanogenic massive sulphide
discoveries (Bisha Main, the NW Zone and the
Harena Zone) are all characterized by having
a gold bearing gossanous surface oxide cap
overlying a supergene sulphide layer, which
in turn lies on top of a main primary
sulphide structure. Typically the oxide cap
has provided an exploration target for gold
and silver, and the supergene sulphides and
primary sulphides have been exploration
targets for base metals (copper and zinc).
Nevsun views the NW Zone massive sulphide
and gold deposit as a potential source of
supplemental feed for the proposed
processing facility at Bisha. The
Company is pleased to continue to build
auxiliary deposits for future growth of the
Bisha Project.
Highlights include:
Gold
Hole NW-012 intersected 8.3 g/t Au over
4.5 meters in oxide
Hole NW-001 intersected 26.84 g/t Au over
3.0 meters in supergene
Hole NW-007 intersected 3.04 g/t Au over
6.0 meters in primary
Hole NW-009 intersected 22.21 g/t Au over
4.7 meters in primary
Copper
Hole NW-002 intersected 1.79% Cu over
12.2 meters in supergene
and 1.51% Cu over 10.82 meters in
primary
Hole NW-009 intersected 1.07% Cu over
33.0 meters in supergene
Hole NW-012 intersected 1.23% Cu over
12.8 meters in primary
Copper and Zinc
Hole NW005 intersected 0.88% Cu and 3.12%
Zn over 13.8 meters in primary
Hole NW008 intersected 1.42% Cu and 4.67%
Zn over 22.1 meters in primary
