Nevsun Resources Ltd.: Massive Sulphides Intersected at
375 Meters, Extending the Vertical Depth of the Bisha
Main Zone by a Further 75 Meters
VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Apr 7, 2004) - Nevsun
Resources Ltd. (NSU/TSX) is pleased to announce the assay results
from an additional 14 diamond drill holes as part of the 30,000
meter current drill program. One of these holes, B-212, has been
drilled to depths of 375 meters to determine the vertical extent
of the deposit and intersected massive sulphides over true widths
of 60+ meters. Assays are pending for this hole. The zone remains
open at depth.
The results continue to reflect a continuity of mineralization
both along strike and down dip and demonstrate significant
potential for a long term mine life from the primary sulphides of
the Bisha Project, subsequent to the mining of the high grade
oxide gold and copper supergene zones near surface.
HIGHLIGHTS:
- Hole B-212 intersected massive sulphides from 346.1 to 418.4
meters, extending the mineralized zone to 375 vertical meters
- Hole B-169 with 33.0 meters grading 6.59% Zn, 1.94% Cu, 92.34 g/t
Ag and 0.97 g/t Au
- Hole B-171 with 35.2 meters grading 8.88% Zn, 1.55% Cu, 72.56 g/t
Ag and 0.93 g/t Au
- Hole B-172 with 30.0 meters grading 8.36% Zn, 1.15% Cu, 55.60 g/t
Ag and 1.09 g/t Au
- Hole B-175 with 22.4 meters grading 9.11% Zn, 1.28% Cu, 74.80 g/t
Ag and 0.72 g/t Au
- Hole B-178 with 35.8 meters grading 6.47% Zn, 1.49% Cu, 55.06 g/t
Ag and 0.73 g/t Au.
Assay results from 13 diamond drill holes at the Bisha Main Zone are
listed below by mineral zones: O-Oxide, S-Supergene sulphides,
P-Primary sulphides.

.........................
Hole B-182 was an exploration hole drilled 2 kilometers to the
southwest of the Main Zone that targeted geophysical responses.
It encountered disseminated sulphides containing 0.93% Zn over
7.1 meters. The targeted gravity anomaly is not adequately
explained and further work is planned. Assays on additional holes
drilled will be released as available.
The reverse circulation drill has arrived on the property and is
operational. A total of 8,000 meters of reverse circulation
drilling is planned to infill the Bisha Main Zone targeting
mostly the oxide gold and supergene copper horizons. The Company
is on schedule to have a third party calculate a resource
statement for the Bisha Main Zone at the end of the second
quarter of this year.
Detailed drilling of the Northwest Zone, another massive sulphide
body discovered in 2003, will be implemented in October of this
year. Additional exploration drilling will also take place during
this time frame.
Recently completed gravity work along with EM, soil geochemical
and geological surveys have earmarked another exploration target
located approximately 8 kilometers southwest of Bisha Main. The
target is interpreted to have a massive sulphides signature.
Drill testing is planned for later this year.
Bill Nielsen, Vice-President of Exploration for Nevsun, a
qualified person under National Instrument 43-101, supervised and
directed all work associated with the drilling program. Nevsun
implemented a QA/QC program, consisting of certified standards,
for the drill program. The analytical methods used for gold and
silver are fire assay with atomic absorption or gravimetric
finish. Induced Coupled Plasma (ICP) is used for silver trace
level values. The analytical methods used for the base metals are
aqua-regia digestion and atomic absorption finish or ICP for
trace level values. Sample preparation and analysis were
conducted at ALS Chemex of Vancouver, Canada.
Forward Looking Statements: The above contains forward looking
statements that are subject to a number of known and unknown
risks, uncertainties and other factors that may cause actual
results to differ materially from those anticipated in our
forward looking statements. Factors that could cause such
differences include: changes in world gold markets, equity
markets, costs and supply of materials relevant to the mining
industry, change in government and changes to regulations
affecting the mining industry. 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.
