Shaft sinking north of the Arctic Circle: After a three-year bidding and negotiation phase, THYSSEN SCHACHTBAU GMBH was awarded a contract in September 2007 by OJSC MMC NORILSK NICKEL (MMC Norilsk Nickel) for "Design, construction and installation of the shaft object complex WS-10 ventilation shaft, Skalistij mine" for the ore mining combine in Norilsk on the Taimyr Peninsula, a Siberian region north of the Arctic Circle. The Norilsk mining district is located in central Siberia in the Arctic Circle region, east of the Yenisey River. In these latitudes, the permafrost thaws to a maximum depth of 6 meters for a short time only during the two summer months due to the constantly prevailing, extremely icy temperatures. The Norilsk mining region is home to very rich ore bodies, from which mainly nickel, copper and platinum are extracted. The WS-10 ventilation shaft is also planned above a very rich ore body and is part of the new "Skalistij" mine complex to be opened up, whose deposit will secure ore production from the Norilsk mining region for decades from the end of 2015. Work on sinking the SKS-1 production shaft, which is positioned around 1,500 meters adjacent to the WS-10 site, is also scheduled to start in the near future. Here, too, we were awarded the contract. The contract volume, which was awarded to THYSSEN SCHACHTBAU GMBH as general contractor, ultimately comprises the construction of two complete mine installations. These two orders were to become the start of extensive follow-up contracts with well-known customers in the raw materials industry in the Russian Federation.
