Polyus Gold International has announced a delay in the launch of operations on Russia's largest gold deposit, Natalka.

      The miner's shares fell 2.4 percent on the London Stock Exchange following the news.

      Investors have not received any clear explanation, but expert point to extreme frosts in the Magadan Region and the delay in construction works related to it.

      Polyus Gold now plans to launch production in mid-2014 instead of early 2014.
