Transport In Winter, Norilsk, Krasnoyarsk Krai, Russia

The ore was formed when the erupting magma became saturated in sulfur, forming globules of pentlandite, chalcopyrite, and other sulfides. These sulfides were then "washed" by the continuing torrent of erupting magma, and upgraded their tenor with nickel, copper, platinum, and palladium.
The current resource known for these mineralized intrusion exceeds 1.8 billion tons. MMC Norilsk Nickel, headquartered in Moscow, is the principal mining operator in Norilsk-Talnakh. The ore is mined underground via several shafts, and a decline. The ore deposits are currently being extracted at more than 1,200 m (3,900 ft) below ground. The ore deposits are drilled from the surface. Nickel production for 2008 amounted to 299.7 thousand metric tonnes. Copper production for 2008 amounted to 419 thousand metric tonnes.
The deposits are being explored by a Russian Government-controlled company. The company is known to be using electromagnetic field geophysics, with loops on surface which are over 1,000 m (3,300 ft) on a side. They are conclusively able to image the conductive nickel ore at depths in excess of 1,800 m (5,900 ft).
