  1. March2011 Developing Copper, Zinc and Gold Deposits at the Asmara Project, Eritrea

  2. Sunridge Gold – Highlights The Asmara Project in Eritrea hosts four deposits. Sunridge has completed independent, TSX 43-101 approved resource estimates on three deposits, EmbaDerho, AdiNefas 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. 2

  3. Sunridge Gold – Highlights Feasibility Study at Debarwa focusing on fast tracking high grade copper zone to production Prefeasibility Studyunderway on three Northern Deposits Major drill programs with five rigs operating by end of first quarter Experienced management team “De-riskification” of region continues Discovery of potential new VMS district in Madagascar Well funded – $24 million in treasury 3

  15. Emba Derho 43-101 Resource Model 15

  16. Emba Derho Scoping Study – Base Case • Completed June 2009 by Wardrop UK – Base Case Study: • Open pit mining at 4 M tonnes per year for 10.4 years (42 Mt out of 62 Mt) - potential mine life extension • Base Case IRR - 21.6% • Initial estimated capex: US$331.8 M, sustaining capital US$67.3 M • Base Case NPV -US$203.9 M at 10% discount rate pre-tax • Produce 200,000 t of Cu & Zn concentrates annually containing 55,000 t Zn, 25,000 t Cu, 20,000 oz Au & 0.6 m oz Ag • Total operating costs - US$21.19/tonne milled 16

  17. Scoping Study – Sensitivity to Metal Prices Historical average metal prices sourced from London Metal Exchange as of June/09 17

  18. Emba Derho Optimization • Opportunities for improving EmbaDerho economics: • Include 95,000 ozs Au @ 0.84 g/t from Oxide Gold Zone in pre-feasibility study • Include AdiNefas and Gupo Gold in Prefeasibility Study • Removal of ~20% internal waste with DMS system • Steepen pit slope. • Drill programs at EmbaDerho, AdiNefas, 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. 18
