The Company conducts exploration in three regions of Russia – on the Taimyr and Kola Peninsulas and in the Zabaykalsky Territory. Through exploration at new and existing mine sites, Nornickel drives increases in its high‑grade and cuprous ore reserves to support future production from existing sites, viewing it as a key driver of its long‑term growth.
