COMMENCEMENT OF COPPER-NICKEL EXPLORATION
Previous exploration results from shaft and cross-cut sampling returned 8m at
1.77% Ni & 4.11% Cu and 10m at 1.53% Ni & 1.87% Cu.
Gippsland Limited today announces that it is mobilising electromagnetic ("EM")
and induced polarisation ("IP") equipment to commence exploration at the Abu
Swayel copper-nickel prospect in Egypt.
The Abu Swayel copper-nickel prospect was one of two known major sources of
copper in ancient Egypt. This ancient mine is situated 160km southeast of Aswan
35km to the northeast of the Company's western group of Wadi Allaqi gold
deposits.
Copper at Abu Swayel was mined by the ancient Egyptians during the Twelfth
Dynasty of the Middle Kingdom (1991-1786 BC) from shallow open cut workings
which can be traced over a length of 180m. In the early part of the 1900s the
Nile Valley Company Limited sank a shallow shaft with a cross-cut at the 22m
level to test the vertical continuity of the mineralisation. This shaft was
deepened to 69m in the 1960s in conjunction with a diamond drilling program of
ten holes to test the down dip continuity of the mineralisation over a strike
length of 200m. Of the 1,205m of drilling completed, only 21 samples ranging
from 1-2m in length were assayed. Three of the holes (DH01, DH02 & DH14)
returned significant Cu and Ni values.
Sampling of the cross-cut in the 1960s gave an average 4.11% Cu, 1.77% Ni,
17.81% Fe and 9.94% S over 8m.

The mineralised host unit is an elongated, lenticular amphibolite body which can
be traced for some 500m along a northwest-southeast strike and enclosed by a
garnet-mica schist. Copper-nickel mineralisation occurs both in the amphibolite
body and in enclosing host. The mineralisation contains chalcopyrite, pyrite,
nickel-bearing violarite, and ilmenite. The relict textures of the pyrite and
the violarite show the primary ores to be pyrrhotite, pentlandite and
chalcopyrite. The drilling intersected a persistent, apparently stratiform,
sulphide-bearing zone of variable thickness, that hosts the mineralised
amphibolite body.
Except for geological mapping undertaken by Gippsland there has been no
exploration outside of the immediate vicinity of the ancient workings since the
early 1960s. The results of the previous exploration clearly show that
mineralisation is present at grades and over widths that would be readily
detected by geophysical methods such EM and IP techniques.
The Abu Swayel licence covers 16km2 of favourable stratigraphy along strike from
the old workings which have not been tested for Cu-Ni mineralisation. Much of
the area is covered by thin wadi sediments which can be readily explored by
means of ground geophysical methods.
The previous exploration results clearly show that copper and nickel
mineralisation is present at substantial grades and a programme of exploration
is required to quantify the contained tonnage of mineralisation. The exploration
programme will include geological mapping, geochemical sampling, EM / IP
together with follow-up drilling of the geophysical anomalies.
Gippsland Executive Chairman stated "Assuming the historical Cu & Ni grades the
mineralised material has an in-situ value of approximately US$1,060 per tonne.
This value, together with a potential platinum credit, presents a very exciting
opportunity for the Company".
