Centamin Egypt Limited26 July 2006 Centamin Egypt Limited Quarterly Report for the Quarter Ended 30 June 2006 Highlights • The Sukari JORC compliant geological resource upgraded to 5.99 millionounces of gold. • Amun Zone resource infill definition programme completed, confirming tenorand extent of mineralisation and increasing the measured and indicatedcategories. Significant results included: RCD497 - 4m @ 13.70g/t RCD498 - 80m @ 2.30g/t RCD499 - 40m @ 2.86g/t RCD508 - 60m @ 2.40g/t RCD509 - 34m @ 3.08g/t RCD513 - 5m @ 10.13g/t & 32m @ 1.91g/t Au RCD522 - 24.6m @ 4.90g/t Au (incl. 8m @ 12.04g/t Au) RCD524 - 45m @ 3.26g/t RCD525 - 18m @ 3.07g/t Au, 49m @ 1.51g/t & 28m @ 2.02g/t RCD526 - 62m @ 2.01g/t Au • Drilling continued in the Pharaoh, Ra and Gazelle Zones, targeted atdefining the continuation of mineralisation to the northern end of the hill.Significant results included: RCD461 - 75m @ 1.91g/t Au (incl. 1m @ 49.8g/t Au) RCD536 - 26m @ 1.65g/t Au from surface D543 - 20m @ 1.86g/t Au 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 theRa - Gazelle zone. • Minister Sameh Fahmy and members of Parliament revisited site, resultingin positive media coverage and increased public interest in the Project. • During the quarter the metallurgical and process flow sheet elements ofthe Feasibility Study were completed. Feasibility Study ("BFS") / Process Plant Acquisition During the fourth quarter the metallurgical and process flow sheet elements ofthe BFS were completed which has allowed the company to commence a search forappropriate items of used process plant. The company is considering the purchase of used process plant items in an effortto reduce both the procurement time and the cost for major plant items. Thesearch has identified a recently closed operation that contains most of theprocess plant items that Centamin will require for the Sukari project. The potential purchase of this plant represents an opportunity to materiallyreduce the cost of development and also accelerate the construction timetable.Testing of the structural integrity of key plant items has been arranged andnegotiations with the plant owner are at an advanced stage. Consequently the completion of the BFS will be delayed while a thorough reviewof this process plant is completed. Sukari Project Resource Modelling The Geological Resource was upgraded by Hellman and Schofield Pty Ltd during thequarter and currently stands at 128.5Mt @ 1.45g/t Au for 5.99 Moz Au at a 0.5g/tAu cut-off. Resources by Confidence Category - Total Resource - Global All DataCut-off Measured Indicated Inferred Total Total Tonnes Grade Tonnes Grade Tonnes Grade Tonnes Grade Ounces 0.50 35,232,233 1.44 49,764,840 1.47 43,502,598 1.44 128,499,671 1.45 5,994,550 1.00 17,921,275 2.13 25,577,226 2.19 20,417,375 2.26 63,915,876 2.19 4,510,536 Note to Table: Figures in table may not add correctly due to rounding The measured resources lie in areas where drilling is available at a nominal 25x 25 metre spacing, whilst indicated resources are in areas drilled atapproximately 25 x 50 metre spacing and inferred resources in areas of broaderspaced drilling. The resources are estimates of recoverable tonnes and gradesusing Multiple Indicator Kriging with block support correction. The latest resource report is based on 118,038.45 metres of diamond ("DD") andreverse circulation ("RC") drilling in 607 holes and 10,540 metres of surfacerock chip lines spaced on approximately 25 metre spaced sections. These coverabout 2,500 metres strike length of the deposit and (the drilling extends) to adepth of approximately 700 metres. A database of 55,175 two-metre drill holesample composites and 4,908 two-metre surface rock chip samples provides thebasis for resource estimation. All zones drilled during the quarter recorded significant assay results, whichis very encouraging for defining additional resources and extending themineralisation 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 InfillResource definition drill programme for the BFS during the June quarter 2006.The drilling was designed to convert inferred resources to measured andindicated, to add ounces inside the optimised pit shell, infill identified datagaps in the geological model and to fully define the extent of the porphyrywithin the BFS mine area for infrastructure and mine planning. All these aimswere achieved by the drilling. The mineralisation and porphyry is still open at depth and to the north of theproposed 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 P1porphyry associated with moderate east dipping quartz vein, breccia - shearzones, with haloes of stacked extensional quartz veins andsilica-sericite-carbonate-sulphide-kaolin alteration (Figure 1). Higher gradesare associated with strongly sulphidic (particularly arsenopyrite), hydrothermalbrecciated 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 ofstrong gold mineralisation, confirming the extension of gold mineralisationnorthwards. Drilling is primarily at an inferred resource category on 50m spacedsections, 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 explorationadit, which has previously recorded 38m @ 7.73g/t from rock chip channelsampling. Coarse visible gold in quartz veins were logged at 572 - 575m,corresponding to an assay result of 3m @ 440.6g/t Au, within a massiveintersection of 111m @ 15.06g/t Au (uncut) from 473m. This newly defined high grade zone is outside the main BFS study Amun orebodyand currently defined pit shells, but is similar in style to the Amun Zone MainLode of the old mine that was exploited in ancient times, and seems to representa 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 inthe Ra-Gazelle zone higher up in the porphyry and from mapping, from 11,025N to11,175N, and from 10,650E to the eastern contact of the porphyry. Current pitoptimisations show a deepening of the pit shell in this area. The assay resultshighlight the strong potential for further high grade zones at depth in SukariHill, and in the Ra-Gazelle zone in particular.

RC drillingcontinued on the Mike Track, northern Pharaoh Zone from 11,850N north, andfurther south in the Pharaoh zone on Adit and Accra South tracks. Several zonesof anomalous looking porphyry were intersected near surface from the Mike Trackdrilling, assay results are awaited. DD continued in several areas from the Ra/Gazelle zones to 11,800N, tailing RC pre-collars and following up previouslyintersected mineralisation and is targeted at adding resource ounces. Several RC pre-collars intersected anomalous mineralisation in a near surfaceenvironment (Table 2). 579 returned significant near surface mineralisation of24m @ 1.13g/t Au from 5m, supported by adjacent hole 482. RCD578 had two highergrade zones in weakly mineralised rock all the way downhole (16m @ 1.78g/t from65m). Hole D546, drilled at -10o west into the massive part of the porphyryintersected 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 morethan 200m in strike, and 80m wide, with depth of significant mineralisation upto 40m from surface. This drilling confirms the presence of significant near surface mineralisationand extends the strike length of it south of 11,600N, and north of previouslydefined mineralisation from 11,800N. Diamond tailing of pre-collars in thePharaoh zone is underway, results are awaited.
