Sukari Gold Project Resource Upgrade 9.01 Moz Measured and Indicated, Plus 3.3 Moz Inferred
Centamin Egypt Limited ("Centamin" or "the Company") (TSX: CEE)(ASX: CNT)(AIM: CEY) announces upgrades to the Sukari Gold Project in Egypt.
HIGHLIGHTS
- The Sukari mineral resource upgraded to 9.01 Moz Measured and Indicated, plus 3.3 Moz Inferred
- Measured and Indicated resource increased by 454,552oz or 5% to 9.01 Moz (from 8.56 Moz in July 2008)
- Measured and Indicated resources equal to 73% of global resources
- South of 11312.5N (ie 1.3km of the 2.3km outcrop) the resource is estimated at 8.24 Moz Measured and Indicated and 2.7 Moz Inferred, equal to 89% of global resource
- The resource increase is based on additional assay results from approximately 14,076 metres of drilling received from 30 June 2008 to 02 October 2008
- Total drilling to date exceeds 350,000 metres and drilling continues with 8 rigs on site
- Deepest hole drilled at Sukari (1,018.30 metres) to date stopped due to rig capacity in porphyry mineralization
- Results include 22m @ 14.26g/t Au, 10m @ 45.90g/t Au and 81m @ 4.07g/t Au

Note to Table: Figures in table may not add correctly due to rounding.
The last three months drilling has been very successful in both conversion of Inferred resources to Measured and Indicated resources, and in global resource growth. Measured and Indicated resources grew by approximately 5% to 9.01Moz and the Inferred resource grew by approximately 4% to 3.3Moz. Measured and Indicated resources now account for 73% of the global resource (ie all categories).
Resource growth at Sukari occurred within the Amun Zone from 10100N to 10625N, testing the offset Down Thrust shear structure and deeper porphyry mineralization where mineralization remains open at greater than 1km below wadi level. Drilling also focused on the definition and conversion of Inferred resources to higher confidence categories (Measured and Indicated) around underground mining target the Hapi Zone. In the Pharaoh Zone, significant resource addition occurred from 11250N to 11425N where the Hapi Zone has been defined further along strike. The structure remains open.
Some of the high grade intersections in the estimate included the Hapi Zone at 10250N where hole D1386 intersected highly mineralised porphyry returning 22m @ 14.26g/t Au from 257m. In the Down Thrust structure at 10275N, hole D1366 intersected 10m @ 45.90g/t Au from 511m and in the Pharaoh Zone at 11275N, hole D1364 returned 81m @ 4.07g/t Au from 473m. Details on these and other significant intersections are in the table below.

Note to table: Intervals shown are down hole intercepts, drilled at high
angles relative to the internal mineralized structures and
the Sukari Porphyry.
Planned drilling will continue in the Pharaoh Zone to define the Hapi Zone and related high grade structures north along strike. In the Amun Zone, drilling will continue to outline the promising porphyry mineralization at depth below the Down Thrust structure.
