VANCOUVER, BC--(Marketwired - July 17, 2017) - Turquoise Hill Resources (NYSE: TRQ) (NASDAQ: TRQ) (TSX: TRQ) today announced second quarter 2017 production for Oyu Tolgoi.

Jeff Tygesen, Chief Executive Officer of Turquoise Hill, said, "Oyu Tolgoi's second quarter production results were as planned. Ore treated in the quarter was impacted by a scheduled five-day maintenance shutdown in May, which was successfully completed. Concentrator throughput for the first half of 2017 continued to perform well as did material mined."

In Q2'17, material mined increased 3.5% over Q1'17 while grades for the quarter were flat compared to Q1'17. Copper and gold production for Q2'17 was essentially in-line with Q1'17 production despite the planned maintenance shutdown. Sales of copper in Q2'17 decreased 5.6% over Q1'17 due to lower concentrate volumes during the quarter. Gold sales in Q2'17 decreased 28.1% over Q1'17 due to sales in Q1'17 including some higher-grade concentrate from Q4'16.

Oyu Tolgoi is expected to produce 130,000 to 160,000 tonnes of copper and 100,000 to 140,000 ounces of gold in concentrates for 2017. Open-pit operations are expected to mine in Phases 4 and 6 during the year. In addition, stockpiled ore will continue to be processed during 2017.
