RCD526 - 62m @ 2.01g/t Au
* Drilling continued in the Pharaoh, Ra and Gazelle Zones, targeted at
defining the continuation of mineralisation to the northern end of the hill.
Significant results included:

RCD569 - 44m @ 2.26g/t Au
RCD570 - 11m @ 2.66g/t Au
RCD578 - 16m @ 1.76g/t Au
* Spectacular intersection of 111m @ 15.06g/t Au recorded in RCD553,
identifying a new high grade, thick quartz vein - shear system at depth in the
Ra - Gazelle zone.
* Minister Sameh Fahmy and members of Parliament revisited site, resulting
in positive media coverage and increased public interest in the Project.
* During the quarter the metallurgical and process flow sheet elements of
the Feasibility Study were completed.
Feasibility Study ("BFS") / Process Plant Acquisition
During the fourth quarter the metallurgical and process flow sheet elements of
the BFS were completed which has allowed the company to commence a search for
appropriate items of used process plant.
The company is considering the purchase of used process plant items in an effort
to reduce both the procurement time and the cost for major plant items. The
search has identified a recently closed operation that contains most of the
process plant items that Centamin will require for the Sukari project.
The potential purchase of this plant represents an opportunity to materially
reduce the cost of development and also accelerate the construction timetable.
Testing of the structural integrity of key plant items has been arranged and
negotiations with the plant owner are at an advanced stage.
Consequently the completion of the BFS will be delayed while a thorough review
of this process plant is completed.
Sukari Project
Resource Modelling
The Geological Resource was upgraded by Hellman and Schofield Pty Ltd during the
quarter and currently stands at 128.5Mt @ 1.45g/t Au for 5.99 Moz Au at a 0.5g/t
Au cut-off.

The measured resources lie in areas where drilling is available at a nominal 25
x 25 metre spacing, whilst indicated resources are in areas drilled at
approximately 25 x 50 metre spacing and inferred resources in areas of broader
spaced drilling. The resources are estimates of recoverable tonnes and grades
using Multiple Indicator Kriging with block support correction.
The latest resource report is based on 118,038.45 metres of diamond ("DD") and
reverse circulation ("RC") drilling in 607 holes and 10,540 metres of surface
rock chip lines spaced on approximately 25 metre spaced sections. These cover
about 2,500 metres strike length of the deposit and (the drilling extends) to a
depth of approximately 700 metres. A database of 55,175 two-metre drill hole
sample composites and 4,908 two-metre surface rock chip samples provides the
basis for resource estimation.
All zones drilled during the quarter recorded significant assay results, which
is very encouraging for defining additional resources and extending the
mineralisation zone at Sukari at depth and to the northern end of the hill
(12,200N).
Amun Zone (9900N - 10,900N)
All drilling was completed and assay results received for the Amun Zone Infill
Resource definition drill programme for the BFS during the June quarter 2006.
The drilling was designed to convert inferred resources to measured and
indicated, to add ounces inside the optimised pit shell, infill identified data
gaps in the geological model and to fully define the extent of the porphyry
within the BFS mine area for infrastructure and mine planning. All these aims
were achieved by the drilling.
The mineralisation and porphyry is still open at depth and to the north of the
proposed mining operations, and although it appears to narrow in the south,
hasn't conclusively been closed off.
Drilling intersected strong zones of mineralisation in the main Sukari P1
porphyry associated with moderate east dipping quartz vein, breccia - shear
zones, with haloes of stacked extensional quartz veins and
silica-sericite-carbonate-sulphide-kaolin alteration (Figure 1). Higher grades
are associated with strongly sulphidic (particularly arsenopyrite), hydrothermal
brecciated zones, shear zones and milky quartz veins.
Sterilisation drill programmes have been planned for proposed plant site,
tailings and waste dump areas.
Drilling Programmes
Ra - Gazelle Zone (10,900 - 11,400N)
Drilling continued in the Ra - Gazelle zones, intersecting several zones of
strong gold mineralisation, confirming the extension of gold mineralisation
northwards. Drilling is primarily at an inferred resource category on 50m spaced
sections, with some areas 25m spaced.
RCD553 (11,075N) returned spectacular gold grades in several zones down hole
(Table 1). The hole was collared just above the historical Gazelle exploration
adit, which has previously recorded 38m @ 7.73g/t from rock chip channel
sampling. Coarse visible gold in quartz veins were logged at 572 - 575m,
corresponding to an assay result of 3m @ 440.6g/t Au, within a massive
intersection of 111m @ 15.06g/t Au (uncut) from 473m.
This newly defined high grade zone is outside the main BFS study Amun orebody
and currently defined pit shells, but is similar in style to the Amun Zone Main
Lode of the old mine that was exploited in ancient times, and seems to represent
a new zone in the stacked system of high grade quartz veins and shear zones.
The hole was designed to follow up strong mineralisation previously defined in
the Ra-Gazelle zone higher up in the porphyry and from mapping, from 11,025N to
11,175N, and from 10,650E to the eastern contact of the porphyry. Current pit
optimisations show a deepening of the pit shell in this area. The assay results
highlight the strong potential for further high grade zones at depth in Sukari
Hill, and in the Ra-Gazelle zone in particular.

Pharaoh Zone (11,400N - 12,200N)
Drilling is continuing in the Pharaoh Zone, with several holes returning
significant assay results in the northern part of the hill. RC drilling
continued on the Mike Track, northern Pharaoh Zone from 11,850N north, and
further south in the Pharaoh zone on Adit and Accra South tracks. Several zones
of anomalous looking porphyry were intersected near surface from the Mike Track
drilling, assay results are awaited. DD continued in several areas from the Ra/
Gazelle zones to 11,800N, tailing RC pre-collars and following up previously
intersected mineralisation and is targeted at adding resource ounces.
Several RC pre-collars intersected anomalous mineralisation in a near surface
environment (Table 2). 579 returned significant near surface mineralisation of
24m @ 1.13g/t Au from 5m, supported by adjacent hole 482. RCD578 had two higher
grade zones in weakly mineralised rock all the way downhole (16m @ 1.78g/t from
65m).
Hole D546, drilled at -10o west into the massive part of the porphyry
intersected visible gold in a very high grade zone of 3m @ 9.47g/t from 2m,
confirming the surface mineralisation. Even taking into account the non-optimal,
fan-like drilling density in the area, the surface gold zone looks to be more
than 200m in strike, and 80m wide, with depth of significant mineralisation up
to 40m from surface.
This drilling confirms the presence of significant near surface mineralisation
and extends the strike length of it south of 11,600N, and north of previously
defined mineralisation from 11,800N. Diamond tailing of pre-collars in the
Pharaoh zone is underway, results are awaited.
