Rio Tinto halts underground work at Oyu Tolgoi copper mine

· Politics · Mongolia · Australia

Rio Tinto Group suspended underground operations at its massive Oyu Tolgoi copper mine in Mongolia, one of the world's largest copper developments. The suspension affects a key source of copper supply at a time when demand for the metal is rising because of electrification and data-centre construction, adding to price risk for manufacturers.

Why it matters：Copper is a bottleneck commodity for electrification and AI infrastructure, so a halt at a major mine tightens an already strained global market.

Key points

  • Rio Tinto suspended underground operations at Oyu Tolgoi.
  • The mine is in Mongolia.
