Turquoise Hill Resources Ltd. ("Turquoise Hill" or the "Company") announces that it was successful in obtaining a temporary order (“Order”) on its application for urgent interim relief in the arbitration proceedings with Rio Tinto International Holdings Limited (RTIHL) and a related party. As
a result of the Order, until further order of the arbitrator, Rio Tinto may not use the parties’ existing contractual arrangements to:
• authorize re-profiling negotiations with project lenders in a manner that would render Oyu Tolgoi LLC unable to execute an offering of bonds in 2021; or
• restrict Turquoise Hill from engaging on funding and other matters with its fellow OT stakeholders, including its valued partner Erdenes Oyu Tolgoi LLC and the Government of Mongolia.
Pursuant to the Order, the parties are to return before the arbitrator on March 2, 2021 to apply for any further relief considered necessary prior to the hearing of the arbitration, including whether the Order’s temporary injunction should continue.
