Rio Tinto resumes copper exports from massive Mongolian mine www.bloomberg.com
Rio Tinto Group has resumed exports of copper concentrate from its vast Oyu Tolgoi copper mine in Mongolia following a short protest.
The protesters began a blockade of a key road on Wednesday morning local time, preventing trucks from hauling mined copper to the border with China. The reason for the action wasn’t immediately clear, but the mine is controversial in Mongolia, where the government has demanded a bigger share of revenue from operations.
“Concentrate export shipments have resumed normal operations,” the mining giant said through its local subsidiary in a statement on social media.
Oyu Tolgoi is one of the world’s biggest copper mines and is being expanded as part of Rio’s strategy to expand sales of the metal underpinning electrification, the global energy transition and increasing demand from data centers.
Rio operates the mine with 66% ownership. The Mongolian government holds the rest.
