Reference information

Comments Chalcopyrite-pyrite, rare molybdenite, associated with quartz diorite and diorite porphyry, plagiogranite. The Tominskiy GOK had an initial planned capacity of 14 Mt/yr of copper ore, which was expected to increase to 28 Mt/yr by the end of the second stage of mine development. RMK was planning to invest a total of 22.2 billion rubles (about $685 million) in the new plant and to produce copper concentrate and copper cathodes. The Tominskiy GOK was expected to be commissioned in December 2014.
