en.Wedoany.com Reported - Rio Tinto's Oyu Tolgoi copper mine in Mongolia has resumed copper concentrate shipments. The resumption came one day after protesters blocked a key transport route, causing a brief disruption in exports from this world-class copper mining project. In a statement on social media, Oyu Tolgoi LLC said that reform movement organizers intercepted cargo trucks heading to the China-Mongolia border on Wednesday, and concentrate exports have now returned to normal, though the company did not disclose whether an agreement had been reached with the protesters.

The core demand of the protest is for Mongolia to receive a higher share of mining revenue. The mine has proven reserves of approximately 31.1 million tons of copper, 1,328 tons of gold, and 7,600 tons of silver, making it one of the world's largest copper-gold mines. Against the backdrop of rising copper prices and mining value driven by global electrification and new energy demand, the mine has become a key pillar for Rio Tinto's expansion of copper production capacity.

Rio Tinto holds a 66% stake in the Oyu Tolgoi project. The mine produced 345,000 tons of copper concentrate in 2025, a 61% year-on-year increase, primarily driven by the continued ramp-up of underground mining operations. The company expects that with further capacity release from the underground mine, the site could become the world's fourth-largest copper mine by 2030.
