Rio Tinto-backed Turquoise Hill Resources Ltd. said Dec. 14 that concentrate shipments from its Oyu Tolgoi copper-gold mine in Mongolia have resumed.

After discussions with Chinese and Mongolian authorities, Oyu Tolgoi will follow a new joint coal and concentrate crossing route at the Chinese-Mongolian border.

Based on completed trial shipments, Oyu Tolgoi expects shipments to return to pre-suspension levels over the coming weeks.

The shipments were suspended Dec. 1 following new requirements at the China-Mongolia border for using the crossing route. Production at Oyu Tolgoi, however, was unaffected during this period.
