Talvivaara Mining Company Plc. is an internationally significant base metals producer with its primary focus on nickel and zinc. Talvivaara´s main asset is the Talvivaara nickel mine in Sotkamo, Finland. The Talvivaara polymetallic deposits, Kuusilampi and Kolmisoppi, comprise one of the largest known sulphide nickel resources in Europe with 1 121 million tonnes of ore in measured and indicated categories, sufficient to support an anticipated production for several decades. Production at the mine started in October 2008 with the precipitation of the first metal sulphides. The planned annual nickel production is 50,000 tonnes and as by-products the mine will also produce aprox. 90,000 tpa of zinc, aprox.15,000 tpa of copper and c.1,800 tpa of cobalt.
The Group supplies metal intermediaries to companies with metal refining operations and has entered into a 10-year off-take agreement with Norilsk Nickel Harjavalta Oy for the entire output of the mine's nickel and cobalt production at market prices.
On the 25th of January 2010 Talvivaara entered into a long-term Zinc in concentrate streaming agreement with Nyrstar NV. Talvivaara will deliver all of its Zinc in concentrate production to Nyrstar until 1,250,000 metric tonnes has been delivered. Click here to read the Stock Exchange Release.
Talvivaara applies bioheapleaching to extract the metals from ore. The Group demonstrated the viability of this technology first on large on-site pilot trials using the Talvivaara ore and subsequently, since July 2008, in production scale heaps. The leaching process has been shown to be heat generating and therefore suitable for the sub-arctic climatic conditions of Eastern Finland.
The Talvivaara ore body is well-suited for open pit mining due to thin overburden, favourable resource geometry and a low waste to ore ratio. The ore is relatively low grade, but well-suited to bioleaching due to its high sulphide content.
