Sunridge Gold – Highlights

The Asmara Project in Eritrea hosts four deposits, three of which, Emba Derho, Adi Nefas and Debarwa, have combined TSX 43-101 approved Indicated resources totaling:

• 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.

Sunridge Gold – Highlights

• Feasibility underway at Debarwa. Option to mine and direct ship 18-20% copper material being studied.  Estimated capital cost of “DSO” mine ~$15 million

• Prefeasibility Study on Northern Deposits (Emba Derho, Adi Nefas, Gupo, and overlap on Debarwa) deposits early in 2011

• Definition drilling begun at Debarwa. Expansion drilling to start at Emba Derho and Adi Nefas in January 2011

• Expansion drilling scheduled for late 2010/early 2011 at Adi Nefas and Debarwa

• “De-riskification” of region continues – Bisha Mine on track for com-missioning late 2010

• Discovery of potential new VMS district in Madagascar – drilling to begin in spring 2011

• Well funded to complete all studies and exploration work over next couple of years – over $28 million in treasury

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

•Removal of ~20% internal waste with DMS system

Madagascar – Besakoa Project

A New Emerging VMS District:• Similar to the initial exploration

data collected at both the Asmara Project and Nevsun’s Bisha Project in Eritrea

• Coincident surface gossans, strong soil and gravity anomalies, airborne EM conductors

• Identified on the project which represent the surface expression of VMS systems

• Over 10 strong copper, zinc, gold, and lead geochemical anomalies between 1 and 4 kilometres in length

• Numerous large (longer than 1 kilometre) strong gravity anomalies, coincident with elevated base and precious metal values

• Initial drill program planned for early 2011
