Turquoise Hill Announces Third Quarter 2015 Production

VANCOUVER, BC--(Marketwired - October 15, 2015) - Turquoise Hill Resources (NYSE: TRQ) (NASDAQ: TRQ) (TSX: TRQ) today announced the third quarter 2015 production for Oyu Tolgoi.

Jeff Tygesen, Turquoise Hill Chief Executive Officer, said, "Third quarter mine production at Oyu Tolgoi was at record levels while concentrate produced and contained copper were on par with the previous quarter even considering the planned concentrator shutdown in July. Gold production decreased in the third quarter as a result of lower grades but is expected to increase in the fourth quarter."

During Q3'15, mined production increased 8.5% over Q2'15 due to shorter hauling routes and ongoing productivity initiatives. Copper in concentrates for Q3'15 increased 1.3% due to higher head grades. Gold in concentrates for the quarter decreased 48.5% over Q2'15 due to slower than anticipated access to gold-rich ore. Increased copper and gold production is expected in Q4'15 as higher-grade ore is accessed in the open pit.

Turquoise Hill continues to expect Oyu Tolgoi to produce 175,000 to 195,000 tonnes of copper and 600,000 to 700,000 ounces of gold in concentrates in 2015. The Company expects copper production to be at the top of the range while gold production is expected to be in the middle of the range.

Following the filing of revised schedules for the 2015 Oyu Tolgoi Feasibility Study with the Mongolian Minerals Council in August, pre-start activities are underway in parallel with an update to the capital estimate, which is expected to be completed in Q1'16. Pre-start activities include ramp-up of the owners and EPCM team, re-estimate activities, detailed engineering and early procurement for equipment and materials required for necessary critical works that are key enablers for recommencement of underground lateral development mining activity. The Company continues to expect signing of project financing by the end of 2015 and the decision for underground construction in early Q2'16.
