On February 24, Nornickel announced that it has partially suspended its mines Oktyabrsky and Taimyrsky.

On February 12, during tunnelling operations, natural groundwater inflow was detected at the 350 meters depth mark in the mine headwall at Oktyabrsky mine. Due to the increased water inflow to the drainage systems of the mine and in accordance with safety procedures and applicable law, the Company has partially suspended operations at the mine until flooding ceases. The waterlogging is currently being eliminated.

Operations at the Taimyrsky mine have also been partially suspended, since there are connected underground workings between the two mines, and water has found its way into this mine's horizon.
