Kazakhstan's largest copper producer Kazakhmys Corp and Kazakh miner KAZ Minerals will also participate in the project, state media added.

CNMC did not respond to a Reuters request for comment.

A major company that has taken the lead in developing China's overseas non-ferrous mineral resources with numerous investments, CNMC also has an electrolytic aluminium project in Kazakhstan.
