what happened
Thiess, a unit of ACS subsidiary CIMIC, has won two five-year mining services contracts in Mongolia, Reuters said on Wednesday. Under the first deal, the company will carry out underground mining services at the Oyu Tolgoi mine, which is managed by Rio Tinto.
The second contract covers asset management of energy resources at the Ukhaa Khudag mine.
why it matters
The news concerns a contractor rather than output itself: long-term deals give Thiess a steady workload for years ahead. Work at Oyu Tolgoi matters to Rio Tinto, so investors watch how contractors keep large mines running without interruption. The value of the contracts was not disclosed.
market impact
Thiess and CIMIC: long-term contracts support the contractor's workload; Rio Tinto: steady operations at Oyu Tolgoi
