VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug. 21, 2013) - Turquoise Hill Resources (TSX:TRQ)(NYSE:TRQ)(NASDAQ:TRQ) announced today that it has entered into a pre-bid acceptance deed with Shanxi Donghui Coal Coking & Chemicals Group Co., Ltd ("Shanxi") in respect of 108,502,084 ordinary shares representing approximately 14.9% of the issued and outstanding ordinary shares (the "Sale Shares") in Inova Resources Limited (formerly Ivanhoe Australia Limited) ("Inova") (TSX:IVA)(ASX:IVA) and notes Shanxi's announcement regarding its intention to make a takeover bid for all of the issued shares in Inova at AUD$0.22 cash (equivalent to approximately CAD$0.21 on today's date) per share (the" Takeover Offer"). The Takeover Offer is subject to a number of conditions, including regulatory approvals and a 51% minimum acceptance condition.

Under the pre-bid acceptance deed:

• Turquoise Hill agreed to procure that its wholly-owned subsidiary, IAL Holdings Singapore Pte Ltd ("IAL"), accept the Takeover Offer in respect of the Sale Shares by not later than five business days after the day on which Shanxi declares or announces that (except for the 51% minimum ownership condition) all of the conditions to the Takeover Offer have been satisfied or waived.
• IAL is not required to accept the Takeover Offer in respect of the Sale Shares earlier than two weeks after the date of the offers under the Takeover Offer or if a superior proposal is publicly announced or made which is not at least matched by Shanxi within five business days.

Turquoise Hill has advised Inova that, unless a superior proposal emerges, it intends to procure that IAL accept the Takeover Offer in respect of all of the other Inova shares held by IAL, but it does not intend to do so before IAL accepts the Takeover Offer in respect of the Sale Shares. In total (including the Sale Shares), IAL currently holds 409,488,666 ordinary shares representing approximately 56.2% of the issued and outstanding ordinary shares in Inova, which, based on the announced AUD$0.22 cash per share offer price, equates to approximately AUD$90 million. If Turquoise Hill accepts the the Takeover Offer only in respect of the Sale Shares, Turquoise Hill will continue to own 300,986,582 ordinary shares representing approximately 41.3% of the issued and outstanding ordinary shares in Inova.

A copy of the pre-bid acceptance deed, and further details of the Takeover Offer (including the bid conditions), have been released by Shanxi in its announcement earlier today.

Rio Tinto plc indirectly owns approximately a 51% interest in Turquoise Hill.
