Norilsk Division Completes Repairs at Oktyabrsky & Taimyrsky Mines
Nornickel has stopped water inflow at the Oktyabrsky mine and confirms the resumption of production at the Oktyabrsky and Taimyrsky mines in accordance with the remediation plan. On March 25th, the second phase was completed: additional water barriers were installed, the adjacent workings were filled with backfill mix, and water was released. On March 27th, water flow was stopped by closing the valves after the stowing mix had solidified. More than 32 kt of concrete mixture was poured into the mine workings during the two stages.
The third stage of the plan includes a set of measures to restore normal operations of the mines. Under the plan, Oktyabrsky mine (5.0 mtpa of ore production) will fully resume production in the first ten days of May and Taimyrsky mine (4.3 mtpa) is scheduled to resume production in early June.
The company estimates that the 2021 output guidance in the baseline scenario will fall short of the initially announced plans by about 35 kt of nickel, 65 kt of copper and 22 t of platinum group metals.
