The forward looking statements in this document reflect views held only as of the date of this document.

    3. Overview of European Nickel • Emerging mid-tier nickel laterite producer focused on growth • Production potential of over 50,000tpa Ni within 5 years • Developers of innovative, simple, low cost heap leach process • Technology partner with BHP Billiton • Geographic diversification: Turkey, the Philippines and Albania • Attributable nickel resource base of ≈2.1 million tonnes (JORC 1Mt) • Highly experienced and strong management team • Listed on London’s AIM with good liquidity. Ticker: ENK • Ambition: To be mid-tier, low cost global Ni laterite producer 3

    4. Nickel Laterite Processing • Laterites are the future of nickel – majority of resources in the ground • Unlike sulphides, no upgrade steps • Two main processing routes • Ferronickel smelting • Reduce total orebody in kilns with coal/oil • Smelt total orebody to molten state • Production of 20-40% ferronickel product • High Pressure Acid Leach (HPAL) • Subject total orebody to high temperatures & pressure in sulphuric acid • Refiner liquor • Production of 99.99% nickel metal 4

    5. Drawbacks • Limited use of orebody • Narrow constraints of “other” ore components • Ferronickel smelting, low iron saprolites • HPAL, low magnesium limonites • Rest of ore body waste • High capital costs • $2-4bn for 40-60ktpa nickel production • Operating costs • Energy dependant 5

    6. Alternatives • Caron process • Ammonia leach, one operation • Chinese processing • Pig nickel • Blast furnaces • High coking coal, inefficient, 4-8% ferronickel, impure, polluting, high operating costs, very low capital • Ferronickel smelters • High energy consumption, 8-12% ferronickel, impure, polluting, high operating costs, low capital costs • Heap leaching 6

    7. Heap Leaching • Common in copper, gold industry • 25 years experience to very large scale • Low capital costs, plastic and pumps • Low operating costs, no moving parts • Environmentally benign • Wider range of orebody can be treated Ideal for nickel laterite treatment? 7

    8. Metallurgical Development • Metallurgical development can be expensive • Akin to geological exploration, maybe not as black and white • Can be time consuming and difficult to stage develop • Laboratory work • Large scale tests • Pilot scales tests • Full scale development • Short-cuts could be expensive • Aim is to have the Financing Bank’s engineers sign off on the process 8

    9. Development of the Çaldağ Project, Turkey • Initial laboratory tests positive • Decision to fast track into pilot scale to reduce time & development costs • New intermediary product, Mixed Hydroxide product (MHP) to further reduce full scale capital costs • Higher risk but risk assessment identified: • Major risk in scale up to full height heap • New product MHP required market development so sufficient material required • Demonstration of process to local stakeholders identified as critical 9

    14. The Financing Route • Private equity funded for first 2 years • Convertible note from Standard Bank $2.5m November 2003 • IPO on AIM £15m March 2004 • Options exercised by BHP Billiton $10m 2004/2005 as milestones achieved • Bankable feasibility study completed March 2006 • Equity raising $155m May 2006 • Development started 17

    15. Technology development • From start of project to bankable equity raising was approx. 30 months • Heap leaching demonstrated to independent engineers satisfaction • Product circulated to various refineries & smelters and price structure developed • Local stakeholders satisfied with environmental aspects of the technology • Government EIA granted 18

    16. Not All Risks Can Be Factored In….. • EIA approved by Turkish Govt. in January 2006 • Equator Principles compliant ESIA in April 2006 • Forestry application in June 2006 • Furore over 1 million trees felled by developer outside Istanbul in Sept 2006 • Freeze on grant of forestry permits • Turkish Govt. election period from July – Sept 2007 • Visit by Minister Eroğlu to the site in Dec 2007 • ENK planted over 11,000 trees during 2007 • ENK’s 1st Sustainability Review published in March 2008 • Implementing ICMM Principles for Sustainable Development & Voluntary Principles on Security and Human Rights • Forestry permit application submitted May 2008 19

    17. Overview of the Çaldağ Project • 100% ownership • JORC proven reserve of 375,000t contained Ni • Production target 20,000tpa Ni, 1,200tpa Co • Life of Mine 15 years • Total nickel production 258,000t Ni • Open pit, low cost operation • LOM off-take agreement with BHP Billiton • Located close to deep water port Izmir • Awaiting forestry permit 20

    18. Establishing a Mid-Tier Nickel Producer • European Nickel is leveraging off its simple, low cost technology to become a mid-tier nickel producer • Heap leach technology applicable on equatorial laterites • Permeability & recovery in a high rainfall region • Product enhancements • Technology has enabled European Nickel to acquire strategic stakes in juniors with large resources but no metallurgical ‘know how’ • JV with Rusina Mining on Acoje deposit in Philippines • 19.3% stake in Toledo Mining • Combined, these 3 projects have potential of 90,000tpa 21

    19. Conclusion • Metallurgical development • Not for the faint hearted • Will cost more than you budgeted • Assistance from Major (BHPB) invaluable • Clear target required • Short-cuts traded off against risk and expenditure • Financing development • Continued evaluation on economics, meeting the investment grade 22

    20. The New Industry Paradigm • Costs through the roof – construction, materials, diesel, raw materials • Skills shortage – all key disciplines across all continents • Rise of NGOs in 24/7 news media world • Credit crunch 23

    21. European Nickel Investment Case • Exposure to nickel - strong fundamentals • Low cost entry into laterites – the future of nickel • Simple heap leach process offers competitive edge over other expensive laterite technologies • Geographic diversification • Large resource base and growing • Project pipeline potential of +100,000tpa Ni Focused on a Clear Vision To become a mid-tier global nickel producer, targeting 50,000tpa in five years, by leveraging off the competitive edge offered from proprietary, low cost process 24
