Sunridge Gold – Highlights

The Asmara Project in Eritrea hosts four deposits. Sunridge has completed independent, TSX 43-101 approved resource estimates on three deposits, Emba Derho, Adi Nefas and Debarwa. Combined Indicated resources total:

• 1.28 billion lbs (580,000 tonnes) copper

• 2.5 billion lbs (1,130,000 tonnes) zinc

• 1.05 million oz gold

• 31.8 million oz silver

In addition a fourth deposit, the Gupo Gold deposit, contains an Inferred resource of 189,000 ounces of gold.

•Include Adi Nefas and Gupo Gold in Prefeasibility Study

•Removal of ~20% internal waste with DMS system

•Steepen pit slope.

•Drill programs at Emba Derho, Adi Nefas, Gupo Gold, and Medrizien as part of Prefeasibility study and exploration

•Much stronger copper, zinc, gold, and silver prices since scoping study

•New metallurgical tests show positive recovery results, 92%Cu with 28% concentrate and 88%Zn with 62% concentrate.
