Turquoise Hill to commence arbitration to seek clarity with respect to financing

Turquoise Hill Resources Ltd. (Turquoise Hill or the Company) announced today that it is commencing arbitration proceedings seeking a declaration to clarify the provisions of certain agreements with Rio Tinto International Holdings Limited (RTIHL) and a related party relating to their role and obligations to support the Company in seeking additional financing for the Oyu Tolgoi project. The arbitration is being commenced in British Columbia in accordance with the relevant agreements between the parties.

The commencement of arbitration proceedings follows recent discussions with Rio Tinto relating to the re-profiling of Oyu Tolgoi LLC's existing project debt which was contemplated by the memorandum of understanding (MOU) announced on September 10, 2020. Commencement of the arbitration was approved by the Special Committee of the Company's Board.

The Special Committee concluded that Rio Tinto's approach to the financing of the Oyu Tolgoi project is incompatible with the Company's announced strategy to maximize debt and / or hybrid financing for the Oyu Tolgoi project so as to minimize the size, and defer the timing, of an equity rights offering (if any). The Special Committee believes that the arbitration will provide needed clarity from an independent third party as to the parties' respective rights and obligations with respect to the financing process. The arbitration process is confidential, and it is expected to take between 3 and 5 months to reach a decision. The arbitrator's decision will be final and binding on the parties.

As contemplated in the MOU, the Company is actively advancing its examination and evaluation of financing options for the Oyu Tolgoi project that could address its disclosed funding gap, in whole or in part. Such options include additional debt from banks or international financial institutions, an offering of global medium-term notes and a gold streaming transaction. It is expected that details of the Company's preferred funding options will be presented to Rio Tinto for consideration in accordance with the MOU prior to December 31, 2020.

there may be other factorsthat cause actions, eventsor results not to be as anticipated, estimated or intended. All such forward-looking statements and information are based on certain assumptions and analyses made by the Company's management in light of their

experience and perception of historical trends, current conditionsand expected future developments, aswell asother factorsmanagement believes are reasonable and appropriate in the circumstances. These statements, however, are subject to a variety of risks and

uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statementsor information.

With respect to forward-looking information concerning the continued operation and development of Oyu Tolgoi, the Company hasbased its assumptions and analyses on certain factors which are inherently uncertain. Uncertainties and assumptions include, among others: the timing and cost of the construction and expansion of mining and processing facilities; the timing and availability of a long-term domestic power source (or the availability of financing for the Company or the Government of Mongolia to construct such a source) for Oyu Tolgoi; the ability to secure and draw down on the supplemental debt under the Oyu Tolgoi project financing facility and the availability of additional financing on terms reasonably acceptable to Oyu Tolgoi LLC, Rio Tinto and the Company to further develop Oyu Tolgoi as well as the

status and nature of the Company'songoing discussionswith Rio Tinto plc and itssubsidiarieswith respect to future funding plansand requirements (including as contemplated by the MoU); the potential impact of COVID-19; the impact of changes in, changes in

interpretation to or changesin enforcement of, laws, regulationsand government practicesin Mongolia; the availability and cost of skilled labour and transportation; the obtaining of (and the terms and timing of obtaining) necessary environmental and other government approvals, consents and permits; delays, and the costs which would result from delays, in the development of the underground mine (which could significantly exceed the costsprojected in OTTR20); projected copper, gold and silver pricesand their market demand; and production estimatesand the anticipated yearly production of copper, gold and silver at Oyu Tolgoi.

The cost, timing and complexitiesof mine construction and development are increased by the remote location of a property such as Oyu

Tolgoi. It iscommon in mining operationsand in the development or expansion of existing facilitiesto experience unexpected problems and delaysduring development, construction and mine start-up. Additionally, although Oyu Tolgoi hasachieved commercial production,

there is no assurance that future development activitieswill result in profitable mining operations.
