SUKARI GOLD PROJECT RESOURCE UPGRADE
520,000oz Gold increase in Measured and Indicated Resource
HIGHLIGHTS
The Sukari mineral resource upgraded to 9.91Moz Measured and Indicated, plus 3.3Moz Inferred
An increase in the Measured and Indicated resource of approximately 520,000oz or 6%
New resource ounces based on assay results of 20,000m of drilling largely from the Pharaoh and Amun Zones, and the deeper Hapi Zone
Drilling indicates that mineralization continues further North of the existing reserve, with continuous high grades in the deeper zones
Significant results included in this upgrade 79m @ 4.48g/t Au and 43m @ 17g/t Au

The recent 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 6% to 9.91Moz, and account for 75% of the global resource (i.e. all categories).
High grade intersections included in the estimate are related to the Hapi Zone and deeper zones of mineralization which include in the Pharaoh Zone; 43m @ 17.00g/t Au from 499m in hole RCD1435* (11250N), 79m @ 4.48g/t Au from 662m in hole D1420* (11275N) and 17m @ 10.49g/t Au from 610m and 55m @ 3.48g/t Au from 641m in hole D1431* (11400N). Please refer to Table 2 below for details on these and other significant intersections.
The drilling shows the high grade Hapi and related zones extend from the far south Amun Zone over 1.5km north to the area of current drilling, and may possibly continue to the northern end of the hill. These zones along the entire strike length of Sukari Hill (2.5km) are the target of current comprehensive infill and extension drilling with 8 diamond drilling rigs.
