PRESS RELEASE 
Public Joint Stock Company «Mining and Metallurgical Company «NORILSK NICKEL» 
(PJSC "MMC "Norilsk Nickel", "Nornickel" or the "Company") 
THE NORILSK DIVISION ADOPTS PLAN TO RESUME OPERATIONS AT OKTIABRSKY AND TAYMIR MINES AND NORILSK CONCENTRATOR 
Moscow, March 16, 2021 - Nornickel, the world's largest producer of palladium and high-grade nickel and a major 
producer of platinum and copper, is planning to restore full capacity of its flooded Oktyabrsky and Taimyrsky mines 
within the next 3-4 months. 
The Company's Norilsk Division has developed a plan, with the base case scenario implying that the Oktyabrsky mine (5.0 
mtpa of ore) will gradually ramp-up in the second half of April - May. The Taimyrsky mine (4.3 mtpa of ore) is 
scheduled to resume mining in early June, with a full recovery expected to take approximately one month. 
The Company is currently implementing a plan to stop the inflow of groundwaters, which has been split into several 
phases: 
  - On March 13th, the first phase was completed with the installation of cofferdams to block the ventilation shaft 
    through which the water is flowing in, which was followed by a water discharge; 
  - On March 15th, the second phase was launched: additional cofferdams are being installed, while the neighbouring 
    workings are being filled with backfill mix, and water is being released. Once the backfill mix has hardened, the 
    water inflow will be shut off by closing the valves.  Over the two phases, approximately 30kt of concrete mix is 
    being poured into the mine workings. 
The process of blocking water inflow is complicated by its high intensity and the geological conditions at the 
locations of the cofferdams' installation. Currently, the Norilsk Division management is operating under the base case 
scenario. Nevertheless, due to the outlined circumstances, the risk of an additional delay in the implementation of 
this plan cannot be completely ruled out. 
At Norilsk Concentrator, the disseminated ore processing circuit (5.2mtpa ore throughput) has been idled and repairs 
are being carried out. The circuit is scheduled to be ready for re-start by April 15th. At the same time, the 
concentrator is currently being inspected by the Federal Service for Environmental, Technological and Nuclear 
Supervision (Rostekhnadzor) and the Company's internal auditors. The exact timing of the restart will be decided based 
on the results of these inspections. 
The Norilsk Concentrator's copper circuit (4mtpa of ore throughput) resumed operations on March 15th after a temporary 
shutdown for technical inspections and repairs. During the downtime, the Zapolyarny mine (the South Cluster project) 
continued mining. 
According to the Company's current base case estimates, metal production volumes are expected to fall short of the 2021 
production guidance as follows: nickel - by approximately 35kt, copper - by 65kt and platinum groups metals - by 22t 
(approximately 710koz). 
"We consistently continue to deliver on the plan to stop the inflow of water into our mines. The company has 
successfully completed phase one, having prepared the necessary groundwork for the suspension of the water inflow. Our 
absolute priority remains health and safety of employees and reliability, we have thus decided to reinforce further the 
water protection structures, which is currently under way. Once the second phase has been completed, the two mines will 
gradually start ramping up. The mining equipment has not been impacted and it is ready to resume operations," said 
Nikolay Utkin, Senior Vice President and Head of the Norilsk Division.
