SUKARI GOLD PROJECT RESOURCE UPGRADE
Centamin, the gold mining group with operations in Egypt, is pleased to announce the following upgrade to its resources:
The Sukari mineral resource upgraded to 10.29Moz Measured and Indicated, plus 3.45Moz Inferred
Total Global Resource increased by 374,000 oz Au Measured and Indicated, and 175,000 oz Inferred
Measured and Indicated resources = 75% of global resources
South of 11312.5N (ie southern half of the Sukari hill outcrop), the Measured and Indicated resource is estimated at 8.94Moz, equal to approximately 87% of the total Measured and Indicated resource
The resource increase is based on additional assay results from approximately 23,274 metres of drilling
The resource dataset comprises of 173,283 two metre down hole composites and surface rock chip samples; compared to 161,646 composites (ie an additional 11,637 composites) in July 2009
High grade intersections included in the resource estimate include 19m @ 13.70g/t Au, 16m @ 8.16g/t Au, 32m @ 5.65g/t Au and 19m @ 4.88g/t Au
Resource drilling continues with 8 rigs on site

Figure 1 - Sukari resource growth graph from April 1997 to December 2009
The drilling effort has been successful in both conversion of Inferred resources to Measured and Indicated and global growth in the Pharaoh and Amun Zones targeting the Hapi Zone. Measured and Indicated resources grew by approximately 4% to 10.29Moz. Measured and Indicated resources account for 75% of the global resource (i.e. all categories). Inferred resources grew by approximately 5% to 3.4Moz.
High grade intersections in the estimate are related to the Hapi Zone and deeper zones of mineralization which include from the Ra Zone; 19m @ 13.70g/t Au from 804m in hole RCD1471 on section 10900N and 16m @ 8.16g/t Au from 547m in hole RCD1479 on section 10700N. In the Pharaoh Zone; 32m @ 5.65g/t Au from 691m in hole RCD1454* (11375N) and 19m @ 4.88g/t Au from 583m in hole D1466* (11700N). Details on these and other significant intersections are in the table below.
The drilling shows the high grade Hapi and related zones extend from the far south Amun Zone north to the area of current drilling in the Ra and Pharaoh zones. These zones, along the entire strike length of the Sukari Hill (2.5km), are the target of current infill and extension drilling with eight diamond coring rigs.

Commenting on the resource upgrade, Josef El-Raghy, Chief Executive Officer and Managing Director of Centamin, said:
"The consistency and quality of the Sukari orebody continues as we make further inroads into the northern half of the Sukari Hill. With construction of Stage 2 of the Sukari plant approaching completion and with the Stage 1 plant design throughput remaining on track to be achieved before the end of 2009, we look forward to the next stage of the Company's evolution from a developer into a substantial gold producer."
