Centamin, the gold mining group with operations in Egypt, is pleased to announce the following upgrade to its gold resources:
v The Sukari gold in-situ mineral resource has increased to 10.99Moz Measured and Indicated, plus 3.5Moz Inferred
v This represents an increased gold resource of 699,000 oz Measured and Indicated, and 74,000 oz Inferred, as at the end of May 2010, and is in spite of a depletion of circa 100,000 ounces of gold due to mining activities
v Measured and Indicated resources represent approximately 76% of global resources
v South of 11312.5N (ie southern half of the Sukari hill outcrop), the Measured and Indicated resource is estimated at 9.29Moz, equal to approximately 83% of the total Measured and Indicated resource
v The resource increase is based on additional assay results from approximately 33,400 metres of drilling
v The resource dataset comprises of 189,983 two metre down hole composites and surface rock chip samples; compared to 173,283 composites (ie an additional 16,700 composites) in December 2009
v High grade intersections included in the resource estimate include 156m @ 2.07g/t Au, 25m @ 3.02g/t Au, 24m @ 3.19g/t Au and 13m @ 4.06g/t Au
v Resource drilling continues with 8 rigs on site

1. The resources are estimates of recoverable tonnes and grades using Multiple Indicator Kriging with block support correction.
2. Measured resources lie in areas where drilling is available at a nominal 25 x 25 metre spacing, Indicated resources occur in areas drilled at approximately 25 x 50 metre spacing and Inferred resources exist in areas of broader spaced drilling.
3. The resource model extends from 9700mN to 12200mN and to a maximum depth of 2mRL (a maximum depth of approximately 1050 metres below wadi level).
4. Mineral resource estimate is adjusted to end of May 2010 mining surface and for historical underground mining voids.
Figure 1 - Sukari resource growth graph from August 2000 to June 2010
The drilling effort has been successful in both conversion of Inferred resources to Measured and Indicated and global growth in the Pharaoh and Amun-Ra Zones targeting the Hapi Zone. Measured and Indicated resources grew by approximately 7% to 10.99Moz. Measured and Indicated resources account for 76% of the global resource (i.e. all categories). Inferred resources grew by approximately 2% to 3.5Moz.
High grade intersections in the estimate are related to the Hapi Zone and deeper zones of mineralization which include from the Amun and Ra Zone; 156m @ 2.07g/t Au from 230m in hole D1529 on section 10625N and 45m @ 2.11g/t Au from 325m in hole D1490 on section 10950N. In the Pharaoh Zone; 13m @ 4.06g/t Au from 600m in hole RCD1509 (11725N) and 24m @ 3.19g/t Au from 311m in hole D1494 (11400N). 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, Chairman of Centamin, said:
"This resource upgrade remains consistent with our average discovery rate of approximately 500,000 oz per quarter over the last few years. The drilling continues to confirm the consistency and scale of the Sukari orebody and places it firmly on the map as one of the major gold discoveries to come into production in recent times."
