FINANCIAL RESULTS

Income in 2017 was $110.9 million compared with $106.6 million in 2016. The increase mainly reflects the impact of adjustments to deferred tax assets, cost reductions and higher copper prices, partially offset by reduced sales volumes resulting from lower production due to lower head grades. Cost of sales for 2017 was $763.8 million compared to $861.8 million reflecting lower volumes of concentrates sold and reduced cost of production as a result of cost savings. Cash generated from operating activities in 2017 was $118.0 million compared with $230.6 million in 2016 reflecting the impact of lower gold revenues and higher interest payments, partly offset by higher copper prices and production cost savings. Capital expenditure on property, plant and equipment was $917.5 million on a cash basis in 2017 compared to $326.3 million in 2016, attributed principally to underground ($835.7 million) with the remainder related to open-pit capital activities.

Turquoise Hill's cash and cash equivalents at December 31, 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 continued through 2017 with softer ores from the Central zone. Due to increased processing of harder ore from Phase 4, concentrator throughput for 2018 is expected to be approximately 102,000 tonnes per day.

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 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. Prior to suspending underground construction in August 2013, underground lateral development at Hugo North Lift 1 had advanced approximately 16 kilometres off Shaft 1.

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 340% between 2018 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

Throughout 2017, the main focus of underground development was underground lateral development, sinking of Shafts 2 and 5, support infrastructure and the convey-to-surface system, which all progressed during the year. In January 2018, the Company announced the sinking of Shaft 2 was complete. At the end of 2017, approximately 89% of the underground workforce were Mongolian nationals. The Company continues to expect the first draw bell in mid-2020 and sustainable first production in 2021.

During Q4'17, Rio Tinto undertook a schedule and cost review. Rio Tinto has provided Turquoise Hill with a high-level overview of the review's outcomes, in which Rio Tinto concluded there were no material changes in project scope, cost or schedule.

Oyu Tolgoi spent $309.0 million on underground expansion during Q4'17 and $835.7 million for 2017. Total underground project spend from January 1, 2016 to December 31, 2017 was approximately $1.1 billion. At the end 2017, the 2016 Oyu Tolgoi Technical Report (the 2016 Technical Report) projected a cumulative underground project spend of approximately $1.5 billion. The approximate $0.4 billion difference between actual and projected spend is primarily comprised of deferred contingency allowances, foreign exchange differences as well as delayed spending associated with Shaft 2 schedule impact and the mine dry. In addition, Oyu Tolgoi had further capital commitments2 of $1.2 billion as of December 31, 2017. At the end of 2017, the underground project had committed 56% of direct project contracts and procurement packages, of which 71% were to Mongolian companies.

During Q4'17, underground lateral development made strong progress, with over 2.2 equivalent kilometres completed, resulting in 6.1 equivalent kilometres for 2017. Lateral development progress for 2017 was in line with development timeline in the 2016 Technical Report. Since the re-start of development, a total of 7.7 equivalent kilometres of lateral development has been completed. The following table provides a breakdown of the various components of completed lateral development since project restart:

During Q4'17, the newly installed 3,500 tonne per day development crusher was consistently operating above nameplate capacity. During Q4'17, eleven underground workshops were completed and were in the process of commissioning. Based on the 2016 Technical Report, lateral development is expected to advance approximately 10.0 kilometres during 2018.

During Q4'17, Shaft 2 sinking reached final depth of 1,284 metres and shaft sinking was completed in January 2018. At the end of 2017, the shaft bottom station was approximately 50% complete and headframe works progressed with the positioning of hoist equipment. Fit out of Shaft 2 is expected to occur throughout 2018. Shaft 2 is key to future increases in lateral development activity.

Shaft 5 sinking progressed approximately 200 metres during Q4'17 and is expected to be complete in Q1'18. During Q4'17, installation of the shaft exhaust fan commenced and is on target to be completed in early Q2'18. 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 December 31, 2017.

Supporting infrastructure progressed during Q4'17. Construction of the new camp was approximately 70% complete at the end of Q4'17, including completion and occupancy of the first two buildings. At the end of 2017, the camp's four remaining buildings were mechanically complete and approved for occupancy by the state commissioning authorities.

During Q4'17, development of the convey-to-surface decline continued to progress with month-on-month improvement resulting from the use of project-wide process optimization techniques. 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.

Full-year 2017 and Q4'17 open-pit operations 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 year ended December 31, 2017.

Full year 2017

Revenue of $939.8 million in 2017 decreased 21.9% over 2016 reflecting lower sales volumes due to reduced copper and gold grades as a result of mining lower grade ore from the open-pit. The reduction in grades, particularly gold grades, was partly offset by record-setting open-pit material mined at Oyu Tolgoi and higher copper prices.

Cost of sales in 2017 was $763.8 million compared to $861.8 million in 2016 reflecting a 12.5% reduction in volumes of concentrates sold and reduced cost of production as a result of cost savings.

Capital expenditure on a cash basis for 2017 was $917.5 million compared to $326.3 million in 2016, comprising amounts attributed to the underground project and open-pit activities of $835.7 million and $81.8 million respectively. Open-pit capital expenditure includes deferred stripping of $34.4 million and tailings storage facility spending of $13.1 million.

Total operating cash costs3 at Oyu Tolgoi were $711.6 million in 2017 compared to $775.3 million in 2016. Lower operating cash costs reflect mining and production efficiency improvements, benefits from cost reduction programs and reduced royalty expense due to lower revenue. This was partly offset by higher open pit material mined and concentrator throughput in 2017, compared to 2016. Operating cash costs include the 5% royalty payable to the Government of Mongolia and exclude deferred stripping costs.

Cost of sales were $2.32 per pound of copper sold in 2017, compared with $2.07 per pound of copper sold in 2016 reflecting lower volumes of metals in concentrate sold and reduced head grades.

Oyu Tolgoi's C1 cash costs3 in 2017 were $1.92 per pound of copper produced, an increase from $1.02 per pound of copper produced in 2016, and are presented net of revenues from gold and silver sales. The increase was mainly due to lower grades and recoveries resulting from the mining of low-grade ore, particularly gold, in 2017.

All-in sustaining costs3 in 2017 were $2.39 per pound of copper produced, compared with $1.48 per pound of copper produced in 2016. The increase was mainly due to reduced gold credits per pound of copper produced.

Fourth Quarter 2017

Revenue of $251.7 million in Q4'17 increased 1.9% over Q3'17 reflecting higher copper prices partly offset by lower concentrate sales volumes.

Q4'17 cost of sales was $182.7 million compared to $197.8 million in Q3'17 reflecting the processing of softer Phase 6 ore and higher average mill head grades.

Capital expenditure on a cash basis for Q4'17 was $330.4 million compared to $234.0 million in Q3'17, comprising amounts attributed to the underground project and open-pit activities of $309.0 million and $21.4 million respectively.

Total operating cash costs4 at Oyu Tolgoi increased to $217.7 million in Q4'17 compared to $161.9 million in Q3'17 mainly due to higher open pit maintenance costs and lower capitalization of production phase stripping costs. Operating cash costs include the 5% royalty payable to the Government of Mongolia and exclude deferred stripping costs.

Cost of sales was $2.32 per pound of copper sold in Q4'17, compared with $2.43 per pound of copper sold in Q3'17 resulting from reduced cost of production due to higher head grades.

Oyu Tolgoi's C1 cash costs4 in Q4'17 were $2.05 per pound of copper produced, an increase from $1.83 per pound of copper produced in Q3'17, due to the impact of higher operating cash costs, partly offset by lower gold sales.

All-in sustaining costs4 in Q4'17 were $2.40 per pound of copper produced, compared with $2.76 per pound of copper produced in Q3'17, mainly due to net inventory write-down reversals incurred in Q4'17 and a decrease in sustaining capital.

Key operational metrics for 2017 and Q4'17 are as follows:

Effective March 1, 2018, Oyu Tolgoi lifted force majeure notice to customers. Safe and normal operations, including underground development, were maintained during the force majeure period, and no production impact is expected. Turquoise Hill expects any force majeure-related sales impact to be made up over the next few quarters.

Oyu Tolgoi power supply

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 took 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 cancellation 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.

On February 15, 2018, Oyu Tolgoi received notification the Government of Mongolia (Government) had cancelled the Power Sector Cooperation Agreement (PSCA), which was signed in August 2014. The Government's cancellation, under Section 1.3 of the PSCA, indicated the Tavan Tolgoi power project was no longer a viable option. As a result of the Government's cancellation, effective February 15, 2018, long-term power for Oyu Tolgoi must be domestically sourced within four years, in accordance with the 2009 Oyu Tolgoi Investment Agreement (Investment Agreement). Oyu Tolgoi, Turquoise Hill and Rio Tinto are committed to fulfilling all requirements under the Investment Agreement and are continuing to evaluate all viable power options, including construction of an Oyu Tolgoi based power plant. A final decision on the outcome, cost or financing of a permanent domestic power supply has not been concluded.

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 December 31, 2017, the aggregate outstanding balance of shareholder loans extended by subsidiaries of the Company to Oyu Tolgoi was $3.9 billion, including accrued interest of $0.4 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 December 31, 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 $0.4 billion.

In June 2016, Oyu Tolgoi drew down approximately $4.3 billion of the project finance facility and used all net proceeds, after settlement of withholding taxes and transaction costs, to pay down shareholder loans payable by Oyu Tolgoi to Turquoise Hill. A $4.2 billion related-party receivable with a Rio Tinto subsidiary was recorded in 2016, as the net proceeds from draw down were placed on deposit with Rio Tinto in accordance with the Company's Cash Management Services Agreement. The Company draws upon this related-party receivable as required in order to fund development and financing of the underground mine. As of December 31, 2017, $1.0 billion had been re-drawn from this related-party receivable, leaving a balance of $3.2 billion. The project finance lenders have agreed a debt cap of $6.0 billion. In addition to the funding drawn down to date, this is an additional $0.1 billion available, subject to certain conditions, under the Company's facility with the Export-Import Bank of the United States, and the potential for an additional $1.6 billion of supplemental debt in the future.

Anti-Corruption Authority Information Request

On March 9, 2018, Oyu Tolgoi LLC (Oyu Tolgoi) received an information request from the Mongolian Anti-Corruption Authority (ACA) to provide financial information relating to Oyu Tolgoi. The request relates to an investigation about possible abuse of power by authorized officials during negotiation of the 2009 Oyu Tolgoi Investment Agreement. There is no indication in the ACA information request to suggest that Oyu Tolgoi is a subject of the investigation.

CORPORATE ACTIVITIES

Effective December 18, 2017, Stephen Jones was appointed to the Company's Board of Directors. Mr. Jones has more than 20 years of experience working for Rio Tinto in Growth and Innovation, Copper and Coal, Aluminium, Iron Ore as well as Technology and Innovation in Australia, Canada, Mongolia and the U.S.

Management changes

In February 2017, Turquoise Hill announced the retirement of Steeve Thibeault, the Company's Chief Financial Officer, effective May 23, 2017. During the search process for Mr. Thibeault's successor, Turquoise Hill's Controller, Owen Thomas, served as acting CFO.

Turquoise Hill appointed Luke Colton as Chief Financial Officer effective October 9, 2017. Mr. Colton has more than 15 years of financial experience and since 2013 served as Chief Financial Officer of Richards Bay Minerals in South Africa.

NON-GAAP MEASURES

The Company presents and refers to the following non-GAAP measures, which are not defined in International Financial Reporting Standards (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.

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 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; the impact of changes in, changes in interpretation to or changes in enforcement of, laws, regulations and government practices in 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 costs projected in the 2016 Oyu Tolgoi Feasibility Study and the 2016 Oyu Tolgoi Technical Report); projected copper, gold and silver prices and their market demand; and production estimates and the anticipated yearly production of copper, gold and silver at Oyu Tolgoi.

The cost, timing and complexities of mine construction and development are increased by the remote location of a property such as Oyu Tolgoi. It is common in mining operations and in the development or expansion of existing facilities to experience unexpected problems and delays during development, construction and mine start-up. Additionally, although Oyu Tolgoi has achieved commercial production, there is no assurance that future development activities will result in profitable mining operations.

The December 31, 2017 MD&A (the MD&A) also contains references to estimates of mineral reserves and mineral resources. The estimation of reserves and resources is inherently uncertain and involves subjective judgments about many relevant factors. The mineral resource estimates contained in the MD&A are inclusive of mineral reserves. Further, mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation (including future production from Oyu Tolgoi, the anticipated tonnages and grades that will be achieved or the indicated level of recovery that will be realized), which may prove to be unreliable. There can be no assurance that these estimates will be accurate or that such mineral reserves and mineral resources can be mined or processed profitably. See the discussion under the headings "Language Regarding Reserves and Resources" and "Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources" in Section 20 - CAUTIONARY STATEMENTS - of the MD&A. Such estimates are, in large part, based on the following:

  • Interpretations of geological data obtained from drill holes and other sampling techniques. Large scale mineral continuity and character of the deposits can be improved with additional drilling and sampling; actual mineralization or formations may be different from those predicted. It may also take many years from the initial phase of drilling before production is possible, and during that time the economic feasibility of exploiting a deposit may change. Reserve and resource estimates are materially dependent on prevailing metal prices and the cost of recovering and processing minerals at the individual mine sites. Market fluctuations in the price of metals or increases in the costs to recover metals or the actual recovery percentage of the metal(s) from the Company's mining projects may render mining of ore reserves uneconomic and affect the Company's operations in a materially adverse manner. Moreover, various short-term operating factors may cause a mining operation to be unprofitable in any particular accounting period;
  • Assumptions relating to commodity prices and exchange rates during the expected life of production, mineralization of the area to be mined, the projected cost of mining, and the results of additional planned development work. Actual future production rates and amounts, revenues, taxes, operating expenses, environmental and regulatory compliance expenditures, development expenditures, and recovery rates may vary substantially from those assumed in the estimates. Any significant change in these assumptions, including changes that result from variances between projected and actual results, could result in material downward revision to current estimates;
  • Assumptions relating to projected future metal prices. The Company uses prices reflecting market pricing projections in the financial modeling for Oyu Tolgoi which are subjective in nature. It should be expected that actual prices will be different than the prices used for such modeling (either higher or lower), and the differences could be significant; and
  • Assumptions relating to the costs and availability of treatment and refining services for the metals mined from Oyu Tolgoi, which require arrangements with third parties and involve the potential for fluctuating costs to transport the metals and fluctuating costs and availability of refining services. These costs can be significantly impacted by a variety of industry-specific as well as regional and global economic factors (including, among others, those which affect commodity prices). Many of these factors are beyond the Company's control.

Readers are cautioned not to place undue reliance on forward-looking information or statements. By their nature, forward-looking statements involve numerous assumptions, inherent risks and uncertainties, both general and specific, which contribute to the possibility that the predicted outcomes will not occur. Events or circumstances could cause the Company's actual results to differ materially from those estimated or projected and expressed in, or implied by, these forward-looking statements. Important factors that could cause actual results to differ from these forward-looking statements are included in the "Risks and Uncertainties" section in the MD&A.

Readers are further cautioned that the list of factors enumerated in the "Risks and Uncertainties" section of the MD&A that may affect future results is not exhaustive. When relying on the Company's forward-looking statements and information to make decisions with respect to the Company, investors and others should carefully consider the foregoing factors and other uncertainties and potential events. Furthermore, the forward-looking statements and information contained in the MD&A are made as of the date of this document and the Company does not undertake any obligation to update or to revise any of the included forward-looking statements or information, whether as a result of new information, future events or otherwise, except as required by applicable law. The forward-looking statements and information contained in the MD&A are expressly qualified by this cautionary statement.
