Emba Derho Optimization
Wardrop - opportunities for improving Emba Derho economics:
•Include 95,000 ozs Au @ 0.84 g/t from Oxide Gold Zone in pre-feasibility study
•Include Adi Nefas and Gupo Gold will be included in Prefeasibility Study
•Medrizien, compelling gold target , is located 500 meters away from Emba Derho and could add surface gold resources
•4,000 meters drilling at Gupo and 1,000 meters in initial drill program for Medrizien, fall 2010
•Steepen pit slope. A generic shallow pit slope (45 degrees) was used in scoping study
