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

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

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

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

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?

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

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

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
