2002-02-07 ASX Announcement Prospectus - Shareholder
Update
PROSPECTUS -NEW ISSUE
The Board of Directors of Gippsland Limited ("Gippsland
or Company") hereby announce that Gippsland
will lodge today at the ASIC and ASX a placement
prospectus for the issue of up to 10,000,000 shares
in Gippsland at the issue price of 12 cents each
to raise up to approximately $1,200,000.
The issue is not underwritten. There is no minimum
level of subscription pursuant to the issue. No
oversubscriptions will be accepted. Gippsland
however is in negotiations with a broking firm
which is a member corporation of the Australian
Stock Exchange Limited, to arrange the placement
on a best endeavours basis. These negotiations
are expected to conclude shortly. Gippsland will
pay a placement fee of 5% (plus GST) of the amount
subscribed (and accepted by Gippsland) to any
holders of dealers licences in respect of application
forms bearing the stamp of such dealers. No brokerage
or stamp duty will be payable by applicants subscribing
for shares.
The purpose of the issue is to raise funds for
the following:
to fund a bankable feasibility study upon the
Abu Dabbab tantalite project located in Egypt
in which the Company has a 50% interest by way
of an incorporated joint venture with the Egyptian
Government; administration of the Company; and
working capital.
This issue opens today and will close on 14 February
2002 or as otherwise determined by the directors
of Gippsland.
The immediate effect of this issue (should it
be fully subscribed) will be to increase cash
reserves by approximately $1,200,000 (less the
expenses of this issue) to enable the Company
to pursue its objectives.
If the maximum number of shares issued pursuant
to this Prospectus are issued they will constitute
14.06% of the presently issued share capital which
currently totals 71,131,127 shares. When aggregated
with the number of options previously issued by
the Company which totals to 500,000 options, the
total percentage of shares in the Company the
subject of this issue will constitute approximately
12.3% of the expanded issued capital of the Company
on a fully diluted basis.
The new ordinary shares will rank equally with
other ordinary shares on issue and will participate
fully in any dividends announced after the date
of allotment. No assurance is given by the directors
of Gippsland as to future dividends since they
are dependent on earnings, the financial condition
of Gippsland and other factors.
ABU DABBAB TANTALITE PROJECT
In order to keep the market fully informed of
the scale and detail of the Abu Dabbab project,
the Company is pleased to provide further details
with respect to geology, past exploration and
the determination of the measured, indicated and
inferred resources announced to the market on
22 January 2002.
Geological Description
The Ta-Nb-Sn mineralization of Abu Dabbab occurs
as disseminated cassiterite and niobio-tantalite,
hosted in a stock of apogranite. The apogranite
has been emplaced along a NW trending shear zone
within a sequence of basic to-ultrabasic rocks
and volcano-clastic sediments. No significant
mineralization is present in the country rocks
surrounding the apogranite, and for modelling
purposes, the deposit limits correspond to the
outline of the apogranitic body.
The apogranite is leucocratic, holocrystalline,
white grey to greenish blue, is mostly fine to
medium grained, and in part shows a porphyritic
texture. The deposit has been subjected to various
alteration processes which are manifest in the
form of greisenization, microclinization, silicification
and albitization.
Previous exploration
As reflected in previous ASX announcements, a
significant amount of exploration work has been
previously completed at Abu Dabbab by successive
Egyptian, Russian and Italian expeditions. The
work was very comprehensive and included in part
the items listed in Table 1.

A second resource estimate was undertaken by
an Egyptian-Italian team which incorporated the
additional sampling data. The method used was
geostatistical in that semi-variograms were determined
using the adit sampling data which were then applied
to a block. The results which were quoted as reserves
(unclassified) and are summarised in Table 3 and
include only that part of the resource above the
level of the adits.

Gippsland Resource Determination
Gippsland has recently completed a resource estimate
for the Abu Dabbab tantalite deposit. The estimate,
which involved a complete reassessment of all
of the available geological data generated from
past exploration programs, brought the resource
categories into line with the JORC Code.
The resources were calculated using a cut-off
of 0.01% Ta2O5. Upper cuts were applied to the
metals based on probability plots of metal distribution.
The method of estimation was oreblock modelling
within a wire frame. Grade interpolation was by
inverse distance squared with appropriate search
radii and orientation determined by semi-variography.
Assignment to the resource categories was based
on sampling density and extent of exploration
work completed. The resource estimation parameters
and criteria are summarised in Attachment "A".
As announced to the ASX on 22 January 2002, the
resource determinations are summarised in Table
4.

of the resource to reserve conversion.
Tantalum Prices - Scoping Study
As is the case with all metals, the price of
tantalum is subject to fluctuation, however contrary
to most industrial metals, the Directors recognise
that the tantalum price is in the long term on
a secular up trend:

TANTALUM - ANALYSIS OF THE METAL & THE MARKET
Robert L Hunziker, M.A. Economic History
Co-Manager NRJ Investment Group Ltd
Los Angeles, California, USA
September 26, 2001
Current long-term contract prices for tantalum
pentoxide (Ta2O5) are generally believed to be
in the order of US$65-75 per pound (US$143 - 187/kg).
Whilst current spot prices for Ta2O5 are in the
order of US$40/lb, due to the long standing price
up-trend for the metal, the Company employed a
price of US$50/lb in the recent Abu Dabbab scoping
study details of which were released to the ASX
market on 4 February 2002.
Whilst the scoping study used the above somewhat
depressed price of US$50/lb for Ta2O5, the Directors
are of the opinion that the long-term price for
the material will be in the order of US$65-75/lb.
It should be noted that the in-situ value of
approximately US$590 million stated in the Company's
ASX announcement dated 22 January 2002 was based
upon the Ta2O5 price of US$70/lb. Had the current
depressed spot Ta2O5 price of US$50/lb been employed,
the in-situ value would total approximately US$412
million. It should be noted also that the value
of in-situ metal does not in itself imply viability
but gives an indication of the scale and potential
of the deposit.
FEASIBILITY STUDY
The Directors are presently considering a number
of proposals from overseas and Australian based
companies wishing to undertake the feasibility
study. The result of these deliberations is expected
to be announced prior to the end of February 2002.
Yours sincerely
John (Jack) Telford
Executive Chairman

The method of estimation was oreblock modelling
within a wire frame. Grade interpolation was
by inverse distance squared with appropriate
search radii and orientation determined by
semi-variography. Assignment to the resource
categories was based on sampling density and
extent of exploration work completed. For
example, Measured resources were restricted
to the zone between 50m below the level of
the adits and the surface. |

Resource
blocks assigned to the Indicated category
are those located above 300m RL which is approximately
50m below the level of the adits, located
within the apogranite and have at least 10
data points within the search ellipse. The
Inferred resources are those blocks having
similar attributes but located below 300m
RL. |
| Effectiveness
of method |
The
ore block modelling technique is an effective
method of determining the resources contained
within the Abu Dabbab deposit. There is sufficient
geological and structural data to be able
to construct a reasonably reliable model upon
which to interpolate the blocks. In all cases,
the criteria used to set up the OBM parameters
were based on geological evidence and supported
by statistical information. |
