China border checks cut Oyu Tolgoi exports by 70%
Rio Tinto's Oyu Tolgoi mine in Mongolia saw a 70% drop in copper concentrate exports due to Chinese border restrictions, according to AP. Daily truck convoys fell to four from 12-13, impacting a mine that produced 113,500 tonnes of copper in Q3. Oyu Tolgoi accounts for 56% of Rio's copper output. The disruption coincides with Rio's expansion of underground mining at the site, targeting 500,000 tonnes annually from 2028-2036.
