Latest developments and short term objectives 2(2) Permitting Finance Supreme Administrative Court rejected all appeals on the Environmental Permit in November 2008 Environmental Permit now final and binding Moderate capex overrun due to late stage scope changes in metals plant (piping) and cost escalations in earth works Expected cash at year end approx. EUR 90 million Metal hedges well in the money Short term objectives Crushing capacity ramp-up Metals production ramp-up Maintain good cash position 6

The fundamentals - Talvivaara s keys to success 1. Huge resource One of the largest known sulphide nickel resources Very low stripping ratio Exploration potential 2. Technological superiority Low cost heap leaching method Advanced metals precipitation method State-of-the-art metals recovery plant Experienced staff 3. Global demand Global demand will pick up eventually Cut backs are decreasing supply Long term growth drivers intact 7

The fundamentals 1. world-class asset One of the largest known sulphide nickel deposits in Europe and a major polymetallic resource Commercially significant amounts of copper, cobalt and zinc Easy and cost-effective to mine as large open pits; minimal overburden Huge exploration potential resource update proves the point Significant exploration potential 8

Strategy Execute development of the two deposits at Talvivaara Achieve planned annual output Achieve strong financial profile Maintain strong cash position Generate cash through production Maintain operating and capital cost discipline Longer term expansion following ramp-up of operations Increase capacity at Talvivaara Consider acquisitions Seek opportunities to utilise bioheapleaching technology Enhancement of metals processing facility To allow processing of challenging polymetallic concentrates from other sources Manganese recovery technology 11

Expansion at Talvivaara Expansion studies being revised due to new geological information Need to re-examine appropriate scale in view of targeted 20-25 year mine life 50% expansion would cost less than 50 million Permit for expansion expected to be available New cash required from operations or from external sources for incremental development Kuusilampi 3km untested ground Kolmisoppi 12

Business development manganese production and autoclave investment Decisions on autoclave and manganese investments deferred due to the global economical situation Polymetallic Concentrates Autoclave investment Mine projects supplying the autoclave feed have been deferred Talvivaara is technically ready to make the decision any time Autoclave Heap CuS ZnS Manganese production Studies continue High quality manganese metal, manganese oxide and manganese sulphate can be produced Customers / partners difficult to engage due to the market conditions Solution Purification NiCoS MnO 13

Financial Update Saila Miettinen-Lähde, Chief Financial Officer 4 December 2008

Talvivaara low cost producer in the low price environment Early experiences from production costs largely in line with expectations confirming low cost producer status Some positive surprises have been seen: Lower than anticipated sulphuric acid consumption Decreasing prices of sulphur, sulphuric acid, electricity and certain other raw materials Expenditure dominated by variable costs 20% / 80% fixed-to-variable ratio in 2009, decreasing to 10% / 90% by 2011 Materials handling slightly behind schedule, resulting in revised 2009 production target of 15,000-18,000 tonnes of nickel vs. the original estimate of approx. 20,000 tonnes Production targets for 2010 and beyond remain unchanged Capex moderately increased due to certain metals plant scope changes and higher than expected earth works costs Production control room 1

Operational expenditure G&A 5% Mining 19% Maintenance 7% Leasing 8% Other 2% Contracting 18% Metals recovery 35% Electricity 7% Fuel 3% Labour 6% Materials handling 32% Consumables 14% Bioheapleaching and water management 9% Chemicals 35% 2009 Opex estimated at approx.

EUR 150-160 million p.a. depending on level of waste mining Working capital in range of EUR 15-25 million assuming factoring of receivables 1 Excluding treatment charge 2

Competitive cash cost of production Average cash cost 1 2009: 4.1/lb nickel ($ 5.1/lb) 2010: 2.1/lb nickel ($ 2.6/lb) 2011: 1.7/lb nickel ($ 2.1/lb) Higher unit cost in 2009 due to Disproportionally high mining and materials handling cost during ramp-up Learning curve in operations EUR/lb 30 25 20 15 10 Cash cost of production (EUR/lb nickel) 2 5 1 By-product credits with the following assumptions: - Zn 0.45/lb ($ 0.56 /lb); net smelter return to Talvivaara 60% - Cu 0.68/lb ($ 0.85 /lb); net smelter return to Talvivaara 80% - Co 8.00/lb ($ 10.00 /lb); net smelter return to Talvivaara 59% - /$ 1.25 0 Dec-08 Jul-09 Jan-10 Aug-10 Feb-11 2 Including by-product credits and treatment charge 3

Capital expenditure update Moderate increase in Capex seen in Q4 2008 due to Design and scope changes in final stages of metals plant construction (piping) Increased final invoicing of certain earth works contracts due to oil price escalations Increased cost of some earth works contracts due to worse than expected digging-to-excavation ratio Certain works for the second line of the metals plant having been carried out ahead of time during the fall Certain remaining Capex items rescheduled to 2010 in order to conserve cash in 2009 No effect on production volumes EUR million 800 600 400 200 0 Feasibility study Actual Capex Targeted leasing Dec-08 Remaining Capex Committed leasing 4

Financing status Project term loan facility of USD 320 million Fully drawn down Estimated EUR amount 235-240 million Cost overrun account of USD 35 million funded from equity and can be used to fund additional project costs as necessary Economic completion expected in mid 2010 followed by reduction of margin from 2.75% to 2.00% above LIBOR Typical project finance covenants Convertible note of EUR 85 million (May 2008) Strategic uses of proceeds (manganese production, autoclaves) deferred to conserve cash for 2009 Estimated cash at year end approx. EUR 90 million 5
