This includes:• 1.4% growth for rich ore (107,000 tonnes);• 5.3% growth for cuprous ore (195,000 tonnes); and• 9.2% growth for disseminated ore (302,000 tonnes).Oktyabrsky mine is the most productive mine in the TaimyrPeninsula, it accounted for 34% of the total mining outputand contributed 44% of nickel extraction, 61% of copperextraction and 51% of PGM extraction.Ore extraction by mine on the Taimyr Peninsulain 2003-2005(%)Kola PeninsulaDuring 2005, the Group continued to put into operation thefirst start-up set of facilities at the Severny-Gluboky mine,which allowed it to compensate for the reduction in ore productionin the Tsentralny open pit mines due to the plannedcurtailment of production because of the depletion of resourcesand increase the nickel grade of the ore from 0.67% to 0.69%and the copper grade – from 0.29% to 0.32%.Ore extraction by mines on the Kola Peninsulain 2003-2005(%)Ore mined and metal grades at the Group's mines(excluding Polus and Stillwater Mining Company)('000 tonnes or as noted)Type of ore 2005 2004 2003Taimyr PeninsulaOktyabrsky mine Rich 3,684 3,855 3,960Cuprous 1,214 1,055 896Disseminated 26 26 28Total 4,924 4,936 4,884Taimyrsky mine Rich 3,263 3,165 2,971Talnakh Mining Department (1) Rich 492 312 128Cuprous 2,456 2,420 2,419Disseminated 502 505 518Total 3,450 3,237 3,065Zapolyarny mine Disseminated 1,223 1,206 1,195Medvezhy Ruchey mine Disseminated 1,528 1,240 1,006Summary Rich 7,439 7,332 7,059Cuprous 3,670 3,475 3,315Disseminated 3,279 2,977 2,746Total ore mined 14,388 13,784 13,120Average metal grades(% or as noted)Nickel 1.70 1.74 1.73Copper 2.97 3.03 3.13PGM (g/tonne) 9.43 – –Kola PeninsulaTsentralny mine Disseminated 4,774 5,124 5,305Severny mine Disseminated 1,302 675 656Severny-Gluboky mine (2) Disseminated – 194 –Kaula-Kotselvaara mine Disseminated 726 699 657Summary Total ore mined 6,802 6,692 6,618MMC NORILSK NICKEL NOT INCLUDINGGOLD MINING ASSETS (POLUS)8Average metal grades(%)Nickel 0.69 0.67 0.66Copper 0.32 0.29 0.29Notes:(1) In 2003, Mayak, Skalistaya and Komsomolskaya mines were included in the Talnakh Mining Department.(2) In 2005, Severny-Gluboky mine was merged with Severny mine.Note:(1) In 2005, Severny-Gluboky mine was merged with Severny mine.Ore and metals extraction by mineson the Taimyr Peninsula in 2005(%)Ore and metals extraction by mineson the Kola Peninsula in 2005(%)
