Feasibility Study
Centamin Egypt Limited
10 September 2002
Centamin Egypt announces completion of Bankable Feasibility Study
- Resource increased from 1.73 million ounces to 2.04 million ounces gold (Southern end of Sukari Hill
only)
- IRR of 28.4% for 2 million tonne per annum processing plant
- Recent drilling on Ra zone of Sukari Hill highly promising for further increase in resources
Centamin Egypt Limited (UK/ASX Ticker: CEY/ CNT) today announces the completion
of the independent review of the Bankable Feasibility Study for the development
of a 2 million tpa processing facility for the Sukari Gold Project in Egypt.
Speaking today, Managing Director Josef El-Raghy said that 'the study forms the
foundation of the company's strategy to become a substantial producer of gold.'
The study which, as a result of recent infill drilling at the Amun Zone and
drilling into the Ra zone also resulted in an increase of the 1.73m ounce
resource to 2.04m ounces, showed cash costs of US$182/ ounce and, at a 8%
discount rate , a NPV of US$23 million. 'When we take into account the company's
view that the resource base will be greatly increased as a result of infill
drilling, then the cash costs have the potential to fall to US$164 /ounce, with
NPV rising to US$55 million on the 2 million tonne per annum scenario' added Mr
El-Raghy.
SNC-Lavalin Australia Pty Ltd (SNA) conducted the review of the metallurgy,
process plant (including tailings disposal), capital cost, operating costs,
infrastructure and implementation. The mine scheduling, pit optimisation and
design work was carried out by Mining Solutions Consultancy Pty Ltd (MS) and are
based on the Measured and Indicated Resources of 2.04m ounces (0.5g/t cut-off)
prepared by Hellman & Schofield Pty Ltd (H&S). Corporate CVs relating to SNA, MS
and H&S are appended to this announcement.
The financial model that was prepared by the company as a result of this
feasibility study is referred to as the Sukari Base Case Model and is derived
from data relating to only the Amun zone (10% of the volume of the Sukari Hill).
It does not take into account the full potential of the project where an
exhaustive drilling campaign continues and has resulted in some spectacular
grades such as 28m @ 6.85g/t including 3m @ 56.83g/t.
The Sukari Base Case Model is the foundation for an additional study for a
larger processing facility in the region of 5 million tonne per annum based on
an upgraded resource figure which is expected to be announced by the end of the
year.
In support of this concept, two additional studies referred to as the Sukari
Base + Inferred Model and the Sukari Inferred Pit Expansion Model have been
developed. These additional models demonstrate the potential upside of the
Project. The Base + Inferred Model takes into account inferred resources, rather
than only the measured and indicated resources used in the Base Case model. The
Inferred Pit Expansion Model assumes that the base case ultimate pit limits
would expand to the larger pit shell limits optimised with the inclusion of the
Inferred resources.

BASE CASE
(Recovered Ounces - 589,411 oz): The base case scenario includes Measured and
Indicated resources and considers the opening of an open pit mine and
construction of a CIP operation treating 2 million tonne per annum of ore.
Forecast cash costs per ounce for the 2 million tonne per annum operation are
$182 per oz over the 6.5 year processing period which includes processing of the
low grade stockpiles after the mining has ceased. During the 5 year mining
period cash costs average $167 per oz.
BASE + INFERRED MODEL
(Recovered Ounces - 646,555 oz): As well as the project reserves (based on
Measured and Indicated resources), the Inferred resources reported in the base
case pit designs have been included in this case. The production schedule and
the cash flow model have been adjusted for longer operation life and lower
mining rates at the later years of the operation.
INFERRED PIT EXPANSION CASE
(Recovered Ounces - 942,452oz): It is assumed that the base case ultimate pit
limits would expand to the larger pit shell limits optimised with the inclusion
of the Inferred resources. The Base + Inferred Case production schedule has been
further extended with mining of quantities in the Stage 5 cutback expansion to
the north.
RESOURCE INCREASE
Infill drilling continues to focus on the Amun zone and into the Ra zone located
in the south of the Sukari hill where approximately 43,000m of drilling has
outlined the following current resources and reserves.
Resources are:-
Cut-off grade Measured and Indicated Inferred Total
g/t Au Mt g/t Au Mt g/t Au Mt g/t Au Ounces(M)
0.5 26.39 1.42 16.88 1.54 43.27 1.47 2.04
1.0 13.48 2.09 8.70 2.33 22.19 2.18 1.56
Mining reserves are:-
Cut-off Proven Probable Total
Tonnes Au g/t Tonnes Au g/t Tonnes Au g/t
0.8 - 1.0g/t 1,353,000 0.89 1,304,000 0.91 2,657,000 0.90
>1.0g/t 5,063,000 2.07 4,828/,000 2.07 9,891,000 2.07
Total >0.8g/t 6,416,000 1.82 6,132,000 1.82 12,548,000 1.82
Due to recent slower than anticipated drilling rates being achieved by the
current contractor (particularly due to equipment breakdowns), the company has
engaged Stanley Mining Services Pty Ltd who are deploying two diamond rigs from
Tanzania. These rigs are expected to arrive at site by the end of the month.
The current infill and step out drilling into the RA Zone has resulted in
additional higher grade Inferred Resources that are outside the existing
optimised pit shell used for the above resource calculations and justifies the
company's decision to continue drilling to expand the current resource.
The Sukari Deposit is a large mineralised system that outcrops for 2.5 km
and is up to 400m wide. The system has been divided into 4 zones; the AMUN, RA,
GAZELLE and PHARAOH with drilling to date focussed in the Amun zone and just
beginning to step out into the RA zone. The mine and plant capacity will be
up-graded as further resources are converted into reserves. It is anticipated
that the Sukari resources will support a 4 to 5 million tonne per annum
operation at the next bankable feasibility study review.
Yours faithfully
Josef El-Raghy
