FINANCIAL RESULTS

In Q2'17, the Company recorded net income attributable to owners of Turquoise Hill of $23.8 million ($0.01 per share) compared with net income attributable to owners of Turquoise Hill of $29.8 ($0.01 per share) in Q2'16, a decrease of $6.0 million as the result of lower copper prices and lower gold sales, partly offset by adjustments to recognize additional deferred tax assets. Cost of sales for Q2'17 was $188.9 million compared with $237.1 million in Q2'16 reflecting lower volumes of concentrates sold, partly offset by an increased cost of production due to grade reductions. Cash generated from operating activities before interest and taxes in Q2'17 was $51.5 million compared with $161.6 million in Q2'16, mainly reflecting the impact of lower production and lower volumes of gold in concentrates sold. Capital expenditure on property, plant and equipment was $205.2 million on a cash basis in Q2'17 compared to $53.3 million in Q2'16, attributed principally to underground and a lesser amount for open-pit capital activities.

Turquoise Hill's cash and cash equivalents at June 30, 2017 were approximately $1.4 billion.

OYU TOLGOI

The Oyu Tolgoi mine is approximately 550 kilometres south of Ulaanbaatar, Mongolia's capital city, and 80 kilometres north of the Mongolia-China border. Mineralization on the property consists of porphyry-style copper, gold, silver and molybdenum contained in a linear structural trend (the Oyu Tolgoi Trend) of deposits throughout this trend. They include, from south to north, the Heruga Deposit, the Oyut deposit and the Hugo Dummett deposits (Hugo South, Hugo North and Hugo North Extension).

The Oyu Tolgoi mine was initially developed as an open-pit operation. The copper concentrator plant, with related facilities and necessary infrastructure, was originally designed to process approximately 100,000 tonnes of ore per day from the Oyut open pit. However since 2014, the concentrator has improved operating practices and gained experience, which has helped achieve a consistent throughput of over 110,000 tonnes per day. This is expected to continue through 2017 with softer ores from the Central zone and eventually the Hugo North Lift 1 block cave.

In August 2013, development of the underground mine was suspended pending resolution of matters with the Government of Mongolia. Following signing of the Oyu Tolgoi Underground Mine Development and Financing Plan (Underground Plan) in May 2015 and the signing of a $4.4 billion project finance facility in December 2015, Oyu Tolgoi received the formal notice to proceed approval by the boards of Turquoise Hill, Rio Tinto and Oyu Tolgoi LLC in May 2016, which was the final requirement for the re-start of underground development. Underground construction recommenced in May 2016.

Oyu Tolgoi is expected to be the world's third-largest copper mine at peak production in 2025. Copper production is expected to increase by more than 300% between 2017 and 2025 when Hugo North Lift 1 reaches peak production. Average production from 2025 to 2030 is expected to be more than 550,000 tonnes of copper per year.

Underground development progress

The main focus of underground development programs during Q2'17 continued to be underground lateral development, sinking of Shafts 2 and 5, support infrastructure and the convey-to-surface system, which all progressed during the quarter. The Company continues to expect production from the first draw bell in mid-2020 and sustainable first production in 2021.

Oyu Tolgoi spent $184.7 million on underground expansion during Q2'17. As of June 30, 2017, total underground project spend since January 1, 2016 was $547.9 million. In addition, Oyu Tolgoi had further capital commitments² of $1.1 billion as of June 30, 2017.

During Q2'17, underground lateral development made good progress with approximately 1.4 equivalent kilometres completed. Since the re-start of development, a total of 4.0 equivalent kilometres of lateral development has been completed.

² Please refer to the NON-GAAP MEASURES section of the press release for further information.

During Q2'17, work at the 1,202 metre level of Shaft 2 was completed. At the end of Q2'17, sinking of the shaft was at 1,220 metres and will continue until the next level at 1,256 metres. Shaft 2 sinking is expected to be complete in 2017 at a final depth of 1,284 metres with fit out occurring over 2018.

Shaft 5 sinking progressed approximately 190 metres during Q2'17. Sinking of Shaft 5 began slower than expected due to an extended construction re-start period and lower productivity with completion now likely in early 2018. During Q2'17, sinking rates increased significantly beyond those seen in Q1'17. The Company expects consistent sinking rates for the balance of 2017. When completed, Shaft 5 will be dedicated to ventilation thereby increasing the capacity for underground activities; however, with good early progress and continued on-plan lateral development, the completion of Shaft 5 sinking in early 2018 is not expected to materially impact the lateral development plan.

The following table outlines the status of shafts for underground development as of June 30, 2017.

Supporting infrastructure progressed during Q2'17 with camp construction activities continuing. The new development crusher and dewatering system were installed and are undergoing commissioning, which will enable additional development crews in the second half of 2017.

During Q2'17, development of the convey-to-surface decline continued to progress. The convey-to-surface system is the eventual route of the full 95,000 tonne per day underground ore delivery system to the concentrator; however, it is not a critical path item for first draw bell planned in mid-2020. Expected completion of the convey-to-surface system is 2022, which will facilitate the ramp up to full production by 2027.

Q2'17 operational performance

Safety is a major focus throughout Oyu Tolgoi's operations and the mine's management is committed to reducing risk and injury. Oyu Tolgoi achieved a strong All Injury Frequency Rate of 0.27 per 200,000 hours worked for the six months ended June 30, 2017.

Key financial metrics for Q2'17 are as follows:

Oyu Tolgoi Key Financial Metrics⁽¹⁾

Revenue of $203.7 million in Q2'17 decreased 14.2% over Q1'17 reflecting lower concentrate sales and lower copper prices.

Q2'17 cost of sales was $188.9 million compared to $194.4 million in Q1'17 reflecting lower volumes of concentrates sold.

Capital expenditure on a cash basis for Q2'17 was $205.2 million compared to $147.9 million in Q1'17, comprising amounts attributed to the underground project and open pit activities of $184.7 million and $20.5 million respectively. Open-pit capital expenditure includes deferred stripping of $11.3 million and tailings storage facility spending of $3.8 million.

Total operating cash costs³ at Oyu Tolgoi were $163.6 million in Q2'17 compared to $168.4 million in Q1'17 driven by lower volumes of concentrates produced. Operating cash costs include the 5% royalty payable to the Government of Mongolia and exclude deferred stripping costs.

Oyu Tolgoi Production Data

All data represents full production and sales on a 100% basis

Oyu Tolgoi's second quarter production results were as planned. Ore treated in the quarter was impacted by a scheduled five-day concentrator maintenance shutdown in May, which was successfully completed. 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. During June 2017, Oyu Tolgoi shipped its three millionth tonne of concentrate.

Operational outlook

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 the year.

New power purchase agreement

On May 12, 2017, Oyu Tolgoi LLC signed a new power purchase agreement (PPA) with the National Power Transmission Grid (NPTG) of Mongolia. The PPA was executed in connection with the power import arrangement between NPTG and the Inner Mongolia Power International Corporation (IMPIC). The new arrangement takes effect on July 4, 2017, subsequent to the expiry of the existing IMPIC agreement, for a term of up to six years, with possibility of early cancelation after the fourth year, if a domestic power plant is commissioned earlier. The extension is essential for Oyu Tolgoi to have secure access to power while it works with the Government of Mongolia on establishing a permanent domestic power source.

With the signing of the Southern Regional Power Sector Cooperation Agreement in August 2014, the Government of Mongolia and Oyu Tolgoi agreed to work together to source bridging power from IMPIC until a permanent domestic power source could be finalized. After approximately two years of collaborative work, the joint negotiation team from the Government and Oyu Tolgoi have secured this bridging power arrangement.

Funding of Oyu Tolgoi by Turquoise Hill

In accordance with the Amended and Restated Shareholders' Agreement (ARSHA) dated June 8, 2011, Turquoise Hill has funded Oyu Tolgoi's cash requirements beyond internally generated cash flows by a combination of equity investment and shareholder debt.

For amounts funded by debt, Oyu Tolgoi must repay such amounts, including accrued interest, before it can pay common share dividends. As of June 30, 2017, the aggregate outstanding balance of shareholder loans extended by subsidiaries of the Company to Oyu Tolgoi was $3.4 billion, including accrued interest of $0.2 billion. These loans bear interest at an effective annual rate of LIBOR plus 6.5%.

In accordance with the ARSHA, a subsidiary of the Company has funded the common share investments in Oyu Tolgoi on behalf of Erdenes. These funded amounts earn interest at an effective annual rate of LIBOR plus 6.5% and are repayable, by Erdenes to a subsidiary of the Company, via a pledge over Erdenes' share of Oyu Tolgoi common share dividends. Erdenes also has the right to reduce the outstanding balance by making cash payments at any time. As of June 30, 2017, the cumulative amount of such funding was $0.8 billion, representing 34% of invested common share equity; unrecognized interest on the funding amounted to $0.3 billion.

CORPORATE ACTIVITIES

Election of directors

The nominees set forth in the Company's management proxy circular dated March 23, 2017 were elected as directors of Turquoise Hill at the Annual Meeting of Shareholders, which took place on May 12, 2017.

NON-GAAP MEASURES

The Company presents and refers to the following non-GAAP measures, which are not defined in IFRS. A description and calculation of each measure is given below and may differ from similarly named measures provided by other issuers. These measures are presented in order to provide investors and other stakeholders with additional understanding of performance and operations at Oyu Tolgoi and are not intended to be used in isolation from, or as a replacement for, measures prepared in accordance with IFRS.

Operating cash costs

The measure of operating cash costs excludes: depreciation and depletion; exploration and evaluation; charges for asset write-down (including write-down of materials and supplies inventory) and includes management services payments to Rio Tinto and management services payments to Turquoise Hill which are eliminated in the consolidated financial statements of the Company.

C1 cash costs

C1 cash costs is a metric representing the cash cost per unit of extracting and processing the Company's principal metal product, copper, to a condition in which it may be delivered to customers net of gold and silver credits from concentrates sold. It is provided in order to support peer group comparability and to provide investors and other stakeholders with additional information about the underlying cash costs of Oyu Tolgoi and the impact of gold and silver credits on the operations' cost structure. C1 cash costs are relevant to understanding the Company's operating profitability and ability to generate cash flow. When calculating costs associated with producing a pound of copper, the Company deducts gold and silver revenue credits as the production cost is reduced as a result of selling these products.

All-in sustaining costs

All-in sustaining costs (AISC) is an extended cash based cost metric providing further information on the aggregate cash, capital and overhead outlay per unit and is intended to reflect the costs of producing the Company's principal metal product, copper, in both the short term and over the life-cycle of its operations; as a result, sustaining capital expenditure on a cash basis is included rather than depreciation. As the measure seeks to present a full cost of copper production associated with sustaining current operations, development project capital is not included. AISC allows Turquoise Hill to assess the ability of Oyu Tolgoi to support sustaining capital expenditures for future production from the generation of operating cash flows.

A reconciliation of total operating cash costs, C1 cash costs and all-in sustaining costs is provided below.

Working capital

Consolidated working capital comprises those components of current assets and liabilities which support and result from the Company's ongoing running of its current operations. It is provided in order to give a quantifiable indication of the Company's short-term cash generation ability and business efficiency. As a measure linked to current operations and sustaining of the business, working capital excludes: non-trade receivables and payables; financing items; cash and cash equivalents; deferred revenue and non-current inventory.

A reconciliation of consolidated working capital to the financial statements and notes is provided below.

Contractual obligations

Section 9 of the MD&A discloses contractual obligations in relation to the Company's lease, purchase and asset retirement obligations. Amounts relating to these obligations are calculated on the basis of the Company carrying out its future business activities and operations as planned at the period end. As such, contractual obligations presented in the MD&A will differ from amounts presented in the financial statements, which are prepared on the basis of minimum uncancellable commitments to pay in the event of contract termination. The MD&A presentation of contractual obligations is provided in order to give an indication of future expenditure, for the disclosed categories, arising from the Company's continuing operations and development projects.

A reconciliation of contractual obligations at June 30, 2017 to the financial statements and notes is provided below.
