Rio Tinto is progressively restarting underground mining at Oyu Tolgoi in Mongolia after a seismic event caused a localised rockfall and injured three employees on October 29. The company said the incident had no structural impact on the underground cave or its operating infrastructure, while safety reviews have been completed, according to its investor materials.

Rio Tinto stock traded at 75.39 euros on Lang & Schwarz at 18:03 CET on Thursday, November 5, 2026. The real-time quote of Rio Tinto stock is available for investors.

Oyu Tolgoi drives copper growth

The latest operating picture strengthens the strategic role of Oyu Tolgoi. Copper production at the Mongolian mine rose 27 percent year over year in the third quarter and 29 percent in the first nine months of 2026. The operation ran at an annualised rate of about 450,000 tonnes during the quarter.

Rio Tinto continues to target average recoverable copper production of about 500,000 tonnes a year from Oyu Tolgoi between 2028 and 2036. That ambition gives the restart importance beyond the immediate disruption, because sustained underground output is central to the group's copper growth profile.

Group output keeps the risk visible

Group copper production was little changed at 205,000 tonnes in the third quarter, while output for the first nine months increased 1 percent. The contrast shows how strongly Oyu Tolgoi is offsetting weaker performance elsewhere in the portfolio.

The company has not quantified lost production or set a timetable for completing the restart. Investors should therefore focus on the next operating updates, including the pace of underground recovery, the normalisation of shipments and whether the ramp-up remains on track.
