Gippsland Limited is pleased to announce the
results of the recently completed resource estimate
for the Abu Dabbab tantalite deposit in Egypt.
The estimate, which involved a complete reassessment
of all of the available geological data generated
from past exploration programs, brings the resource
categories into line with the JORC Code.

Note: minor mismatch in totals due to
rounding of tonnes and grade
The above resources were determined by wire-frame
constrained ore block modelling at a cut-off of
0.01% Ta2O5 (tantalum pentoxide).
The above grades may be compared with the 220g/t
Ta2O5 ores mined at Greenbushes in Western Australia.
To put the scale of the project into perspective,
the combined Measured and Indicated Resources
of 14.1 million tonnes have an in-situ contained
metal value of approximately US$590,000,000 at
present, typical on-going contract Ta2O5 prices
of US$65-75 per pound. This may be equated to
2 million ounces of gold.
The Company plans to commence work on a Bankable
Feasibility Study during January 2002. The study
will be based upon open pit mining and an initial
feed-rate of 1 million tonnes per annum producing
420,000 lbs/year Ta2O5 which the Company believes,
will rank the facility as the world's second largest
Ta2O5 producer. The initial plant design will
make allowance for future expansion to 2 million
tonnes per annum producing 840,000 lbs/year Ta2O5.
Gippsland has commenced discussions with 3 major
consumers of Ta2O5 located in Europe, Japan and
the United States with the view to conclude long-term
off-take agreements.
Gippsland Director and Chief Geologist Dr John
Chisholm stated that the modelling of the deposit
had been completed following a comprehensive review
of the extremely extensive and detailed database
resulting from past exploration undertaken in
the 1970s by Russian geologists and supplementary
Italian exploration in the early 1990s. The mineralisation
occurs within a granitic intrusion with the tantalum
and niobium being distributed relatively consistently
throughout the deposit. The tin content, which
occurs as cassiterite (SnO2), decreases slightly
with depth. The deposit does not contain significant
radioactive elements which cause difficulties
in the exploitation of many tantalite deposits
within Australia and overseas.
Executive Chairman John Telford stated that following
the detailed exploration programs of the 1970s
and the early 1990s, the project was mothballed
due to the then low tantalum pentoxide price and
the lack of suitable technologies capable of processing
fine-grained tantalum ores. Since the mid 1990s,
significant metallurgical advances have been achieved,
particularly with respect to enhanced gravity
separation techniques, such that Abu Dabbab style
ores are now successfully processed in a number
of mining operations both within Australia and
overseas.
Mr Telford stated: "These metallurgical
advances plus the steadily increasing demand for
Ta2O5, provide a most positive outlook for the
project which seats Gippsland as a major force
in the global tantalite business. Over the past
two decades, new applications for tantalum have
been discovered with regularity. Because of the
metal's unique characteristics, research for new
applications is ongoing. Tantalum is a metal of
the future".
The Abu Dabbab project is subject to a 50:50
joint venture between the Egyptian Geological
and Mining Authority (EGSMA) and Gippsland's 100%
owned subsidiary Tantalum International Pty Ltd.
Abu Dabbab is located 770km south of Cairo adjacent
to the western shore of the Red Sea, 75km from
the seaport of Quseir, and 25km from the Marsa
Alam international airport.
Abu Dabbab has free access to unlimited quantities
of process water and is situated in an area which
poses no environmental or archaeological complications.
The project is fully supported by the Egyptian
government and will enjoy a 100% exemption from
Egyptian profits taxation for a period of 20 years.
