As shaft sinking advances, two additional stations will be developed at mine-working depths of 850 metres and 950 metres. Shaft 1 is expected to reach its projected, final depth of 982 metres below surface in early 2020. Shaft 1 ultimately will become the primary ventilation intake shaft during the project’s initial, four-Mtpa production case.

Shaft 2 early-works construction progressing

Shaft 2, to be located approximately 100 metres northeast of Shaft 1, will have an internal diameter of 10 metres. It will be lined with concrete and sunk to a planned, final depth of more than 1,104 metres below surface. It will be equipped with two, 40-tonne, rock-hoisting skips capable of hoisting a total of six million tonnes of ore a year – the single largest hoisting capacity at any mine in Africa.

The headgear for the permanent hoisting facility was designed by South Africa-based Murray & Roberts Cementation. The first seven blasts for Shaft 2’s box cut were successfully completed, with the last two remaining blasts expected to take place before the end of 2018. The blasting will enable the excavation of the box cut to a depth of approximately 29 metres below surface and the construction of the concrete hitch (shaft collar foundation) for the 103-metre-tall concrete headgear that will house the shaft’s permanent hoisting facilities and support the shaft collar. Excavation of the box cut and construction of the hitch foundation is expected to be completed in early 2019, enabling the beginning of the pre-sink that will extend 84 metres below surface.

Underground mining to incorporate highly productive, mechanized methods

Ivanhoe plans to develop the Platreef Mine in phases. The initial annual production rate of four Mtpa is designed to establish an operating platform to support future expansions. This is expected to be followed by a potential doubling of production to eight Mtpa, and then a third expansion phase to a steady-state 12 Mtpa, which would establish Platreef among the largest platinum-group-metals mines in the world.

The mining zones in the current Platreef mine plan occur at depths ranging from approximately 700 metres to 1,200 metres below surface. Shaft 2 will provide primary access to the mining zones; secondary access will be via Shaft 1. During mine production, both shafts also will serve as ventilation intakes. Three additional ventilation exhaust raises are planned to achieve steady-state production.

Planned mining methods will use highly productive, mechanized methods, including long-hole stoping and drift-and-fill mining. Each method will utilize cemented backfill for maximum ore extraction. The ore will be hauled from the stopes to a series of internal ore passes and fed to the bottom of Shaft 2, where it will be crushed and hoisted to surface.

The current mine plan has been improved beyond earlier projections in the 2015 PFS mine plan by optimizing stope design, employing a declining Net Smelter Return (NSR) strategy and targeting higher-grade zones early in the mine’s life. This strategy has increased the grade profile by 23% on a 3PE+Au basis in the first 10 years of operation and by 10% during the life of the mine.

Platreef project financing continuing to advance

Ivanhoe continues to advance the arrangement of project financing for the development of the Platreef Project. Negotiation of a term sheet is progressing well with the Initial Mandated Lead Arrangers (IMLAs), which are KfW IPEX-Bank, a 100% subsidiary of the German promotional bank KfW; Swedish Export Credit Corporation; Nedbank Limited (acting through its Nedbank Corporate and Investment Banking division); and Societe Generale Corporate & Investment Banking.

In October 2018, Export Development Canada (EDC) advised Ivanhoe that it would not renew its IMLA mandate, as it is currently reviewing its market position for South Africa. EDC informed Ivanhoe that its decision was not, based on the due diligence completed to date, related to any specific concern it had with the company or the Platreef Project. In addition preliminary discussions are underway with leading South African financial institutions regarding the financing of the black economic empowerment partners’ contribution to the development capital which would thereby reduce the amount that would otherwise have to be contributed by Ivanhoe on their behalf.

Long-term supply of bulk water secured for the Platreef Mine

On May 7, 2018, Ivanhoe announced the signing of a new agreement to receive local, treated water to supply most of the bulk water needed for the first phase of production at Platreef. The Mogalakwena Local Municipality has agreed to supply a minimum of five million litres of treated water a day for 32 years, beginning in 2022, from the town of Mokopane’s new Masodi Treatment Works. Initial supply will be used in Platreef’s ongoing underground mine development and surface infrastructure construction.

Under terms of the agreement, which is subject to certain suspensive conditions, Ivanplats will provide financial assistance to the municipality for certified costs of up to a maximum of R248 million (approximately $19.6 million) to complete the Masodi treatment plant. Ivanplats will purchase the treated wastewater at a reduced rate of R5 per thousand litres for the first 10 Ml/day to offset a portion of the initial capital contributed.

Development of human resources and job skills

Work progressed on the implementation of Ivanhoe’s Social and Labour Plan (SLP). The company has pledged a total of R160 million ($13 million) during the first five years, culminating in November 2019. The approved plan includes R67 million ($6 million) for the development of job skills among local residents and R88 million ($7 million) for local economic development projects.

2. Kipushi Project
68%-owned by Ivanhoe Mines
Democratic Republic of Congo

The Kipushi copper-zinc-germanium-lead mine, in the DRC, is adjacent to the town of Kipushi and approximately 30 kilometres southwest of Lubumbashi. It is located on the Central African Copperbelt, approximately 250 kilometres southeast of the Kamoa-Kakula Project and less than one kilometre from the Zambian border. Ivanhoe acquired its 68% interest in the Kipushi Project in November 2011; the balance of 32% is held by the state-owned mining company, La Générale des Carrières et des Mines (Gécamines).

Health, safety and community development

At the end of Q3 2018, the Kipushi Project had achieved a total 1,724,816 work hours free of lost-time injuries. On September 16, 2018, it had been a year since a lost-time injury had occurred at the Kipushi Project.

The Kipushi Project operates a potable-water station to supply the municipality with water. This includes power supply, disinfectant chemicals, routine maintenance, security and emergency repair of leaks to the primary reticulation. The Kipushi Project also installed and commissioned new overhead powerlines to the pump station. Other community development projects continued during Q3 and included the Kipushi women’s literacy project.

Kipushi Mineral Resources

The Kipushi Project’s current Mineral Resource estimate was updated with an effective date of June 14, 2018, and was prepared by the MSA Group, of Johannesburg, South Africa, in compliance with 2014 CIM Definition Standards.

Zinc-rich Measured and Indicated Mineral Resources, primarily in the Big Zinc Zone, total 11.78 million tonnes at grades of 35.34% zinc, 0.80% copper, 23 g/t silver and 64 g/t germanium, at a 7% zinc cut-off – containing an estimated 9.2 billion pounds of zinc. Zinc-rich Inferred Mineral Resources total an additional 1.14 million tonnes at grades of 33.77% zinc, 1.24% copper, 12 g/t silver and 62 g/t germanium. The Inferred Mineral Resources are contained partly in the Big Zinc Zone and partly in the Southern Zinc Zone.

Copper-rich Measured and Indicated Mineral Resources contained in the adjacent Fault Zone, Fault Zone Splay and Série Récurrente Zone total an additional 2.29 million tonnes at grades of 4.03% copper, 2.85% zinc, 21 g/t silver and 19 g/t germanium, at a 1.5% copper cut-off – containing 144 million pounds of copper. Copper-rich Inferred Mineral Resources in these zones total an additional 0.44 million tonnes at grades of 3.89% copper, 10.77% zinc, 19 g/t silver and 55 g/t germanium.

The new Mineral Resource estimate incorporates Ivanhoe’s second phase of underground drilling at Kipushi that was completed in 2017.

Pre-feasibility study for Kipushi completed in December 2017;
definitive feasibility study underway

The Kipushi Project’s PFS, announced by Ivanhoe Mines on December 13, 2017, anticipated annual production of an average of 381,000 tonnes of zinc concentrate over an 11-year, initial mine life at a total cash cost of approximately $0.48 per pound of zinc.

Highlights of the PFS, based on a long-term zinc price of $1.10 per pound, include:

• After-tax net present value (NPV) at an 8% real discount rate of $683 million.
• After-tax real internal rate of return (IRR) of 35.3%.
• After-tax project payback period of 2.2 years.
• Pre-production capital costs, including contingency, estimated at $337 million.
• Existing surface and underground infrastructure allows for significantly lower capital costs than comparable greenfield development projects.
• Life-of-mine average planned zinc concentrate production of 381,000 dry tonnes per annum, with a concentrate grade of 59% zinc, is expected to rank Kipushi, once in production, among the world’s largest zinc mines.

Estimated life-of-mine average cash cost of $0.48 per pound of zinc is expected to rank Kipushi, once in production, in the bottom quartile of the cash-cost curve for zinc producers internationally.

The planned primary mining method for the Big Zinc Deposit in the PFS is sublevel, long-hole, open stoping, with cemented backfill. The crown pillars are expected to be mined once adjacent stopes are backfilled using a pillar-retreat mining method. The Big Zinc Deposit is expected to be accessed via the existing decline and without any significant new development. The main levels are planned to be at 60-metre vertical intervals, with sublevels at 30-metre intervals.

Geology and exploration

Work is focused on additional information required for the ongoing feasibility study as well as planning the geological delineation drilling for the underground mine development. The design criteria targeted areas along the edge of the Big Zinc, which presently are inaccessible from the historic workings.

Project development and infrastructure

Significant progress has been made in modernizing the Kipushi Mine’s underground infrastructure as part of preparations for the mine to resume commercial production. In Q3 2018, the Kipushi Project successfully completed initial, pre-production testing as part of the equipment commissioning process for the new, large-capacity rock crusher that has been installed 1,150 metres below surface. The Sandvik jaw crusher has a maximum capacity of 1,085 tonnes an hour. The 54-tonne machine was re-assembled and installed in the crusher chamber after it was disassembled on surface and its pieces were lowered down Shaft 5, which is the Kipushi Mine’s main production shaft.

Ivanhoe completed the upgrading of a significant amount of underground infrastructure at the Kipushi Project, including a series of vertical mine shafts to various depths, with associated head frames, as well as underground mine excavations. A series of crosscuts and ventilation infrastructure still are in working condition. The underground infrastructure also includes a series of pumps to manage the influx of water into the mine.

Shaft 5 is eight metres in diameter and 1,240 metres deep. It now has been upgraded and re-commissioned. The main personnel and material winder has been upgraded and modernized to meet international industry standards and safety criteria. The Shaft 5 rock-hoisting winder now is fully operational, with new head- and tail-ropes also installed. The two newly manufactured rock conveyances (skips) and the supporting frames (bridles) have been installed in the shaft to facilitate the hoisting of rock from the main ore and waste storage silos feeding rock on the 1,200-metre level.

The main haulage way on the 1,150-metre level between the Big Zinc access decline and Shaft 5 rock load-out facilities has been resurfaced with concrete so the mine now can use modern, trackless, mobile machinery.

With the underground upgrading program nearing completion, the project’s focus now will shift to modernizing and upgrading Kipushi’s surface infrastructure to handle and process Kipushi’s high-grade zinc and copper resources.

3. Kamoa-Kakula Copper Project
39.6%-owned by Ivanhoe Mines
Democratic Republic of Congo

The Kamoa-Kakula Copper Project, a joint venture between Ivanhoe Mines and Zijin Mining, has been independently ranked as the largest copper discovery ever made on the African continent – with adjacent prospective exploration areas within the Central African Copperbelt in the Democratic Republic of Congo. The project is approximately 25 kilometres west of the town of Kolwezi and about 270 kilometres west of Lubumbashi.

Ivanhoe sold a 49.5% share interest in Kamoa Holding Limited (Kamoa Holding) to Zijin Mining in December 2015 for an aggregate consideration of $412 million. At the time, Kamoa Holding held a 95% interest in the Kamoa Project. In addition, Ivanhoe sold a 1% share interest in Kamoa Holding to privately-owned Crystal River Global Limited (Crystal River) for $8.32 million – which Crystal River will pay through a non-interest-bearing, 10-year promissory note. Since the conclusion of the Zijin transaction in December 2015, each shareholder has been required to fund expenditures at the Kamoa-Kakula Project in an amount equivalent to its proportionate shareholding interest in Kamoa Holding.

A 5%, non-dilutable interest in the Kamoa-Kakula Project was transferred to the DRC government on September 11, 2012, for no consideration, pursuant to the 2002 DRC mining code. Following the signing of an agreement with the DRC government in November 2016, in which an additional 15% interest in the Kamoa-Kakula Project was transferred to the DRC government, Ivanhoe and Zijin Mining now each hold an indirect, 39.6% interest in the Kamoa-Kakula Project, Crystal River holds an indirect 0.8% interest and the DRC government holds a direct 20% interest. Kamoa Holding holds an 80% interest in the project.

Health and safety at Kamoa-Kakula

At the end of Q3 2018, the Kamoa-Kakula Project had achieved a total of 11,271,678 work hours free of lost-time injuries. It has been approximately seven years since the last lost-time injury occurred at the project. This outstanding achievement reflects the dedication and safety-focused culture of the entire Kamoa-Kakula exploration and development teams.

Kamoa-Kakula Mineral Resources

Ivanhoe issued an updated Mineral Resource estimate for the Kamoa-Kakula Project on February 26, 2018. It included an updated Kakula Mineral Resource estimate and was prepared by Ivanhoe Mines under the direction of Amec Foster Wheeler E&C Services Inc., of Reno, USA, in accordance with the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. The Qualified Persons for the Kamoa-Kakula Mineral Resource estimate are Dr. Harry Parker, RM, SME, and Gordon Seibel, RM, SME, both of Amec Foster Wheeler E&C Services Inc.

Indicated Mineral Resources for the combined Kamoa-Kakula Project now total 1,340 million tonnes grading 2.72% copper, containing 80.7 billion pounds of copper at a 1.0% copper cut-off grade and a minimum thickness of three metres. Kamoa-Kakula also has Inferred Mineral Resources of 315 million tonnes grading 1.87% copper and containing 13.0 billion pounds of copper, also at a 1.0% copper cut-off grade and a minimum thickness of three metres.

The Kakula estimate covers a mineralized strike length of 13.3 kilometres and is based on results from approximately 151,000 metres of drilling in 271 holes completed by December 31, 2017. Indicated Mineral Resources total 585 million tonnes at a grade of 2.92% copper, containing 37.7 billion pounds of copper at a 1% copper cut-off. At a 2% copper cut-off, Indicated Mineral Resources total 330 million tonnes at a 4.07% copper grade, containing 29.6 billion pounds of copper. At a 3% copper cut-off, Indicated Mineral Resources total 174 million tonnes at a grade of 5.62% copper, containing 21.5 billion pounds of copper.

Inferred Mineral Resources total 113 million tonnes at a grade of 1.90% copper, containing 4.7 billion pounds of copper at a 1% copper cut-off. At a 2% copper cut-off, Inferred Mineral Resources total 44 million tonnes at a 2.59% copper grade, containing 2.5 billion pounds of copper. At a 3% copper cut-off, Inferred Mineral Resources total nine million tonnes at a grade of 3.66% copper, containing 0.7 billion pounds of copper.

The average true thickness of the selective mineralized zone (SMZ) at a 1% copper cut-off is 10.1 metres in the Indicated Mineral Resources area and 6.7 metres in the Inferred Mineral Resources area. At a higher 3% copper cut-off, the average true thickness of the SMZ is 4.7 metres in the Indicated Mineral Resources area and 3.3 metres in the Inferred Mineral Resources area.

The Kakula Mineral Resources are defined within a total area of 24.9 square kilometres at a 1% copper cut-off. At the same cut-off grade, the areal extent of Indicated Mineral Resources is 19.4 square kilometres and the areal extent of the Inferred Mineral Resources is 5.5 square kilometres. The Kakula Discovery remains open for significant expansion in multiple directions, while the remainder of the southern parts of the Kamoa-Kakula mining-licence area is virtually untested.

Kakula PFS currently underway

A PFS for phase 1 of the Kamoa-Kakula Project is underway. The study is considering a six-Mtpa mine and concentrator at Kakula, and is expected to be completed early in 2019.

Underground development progressing at the Kakula Deposit

Each of the twin declines at Kakula had been advanced more than 1,000 metres from the portal face toward the mineralized zone at the end of Q3 2018. Construction of the 1,050-metre-level dam has started and is planned to be commissioned by mid-2019. The next priority will be the drifts to the development tip and bottom of Ventilation Shaft 1, which will be developed via raise boring. The 3,535-metre decline development contract is scheduled to be completed by the end of 2018.

The detailed design and tenders for the conveyor system for the main decline, the development tip and west tip one are well advanced. The earthworks design for the surface conveyor drive station has been completed and construction is due to start shortly. All tenders for major conveyor components, including steelwork, drives, belting and pulleys, have been received and are being adjudicated. Tenders for the rock breaker and apron feeders have been adjudicated. Adjudication for the steelwork fabrication has been completed and the order will be placed shortly. Commissioning of the conveyor system is planned to be completed by September 2019.

Contract discussions have been concluded for construction of Ventilation Shaft 1 by raise boring. Bottom access to the shaft is expected via the Kakula declines by January 2019 and reaming of the shaft is expected to start in February 2019.

Exploration activities continue at Kakula and Kamoa North

Exploration drilling during Q3 2018 was split between Kakula and Kamoa North, with 25,298 metres drilled during the quarter in 66 holes. A total of 21 holes were completed in Kamoa North.

Drilling at Kamoa North focused on continued testing of previously identified, shallow, high-grade trends that were not fully evaluated in the 2017 program. The results of this program are due to be released when the final assays are returned. Exploration has continued at Kakula, with known mineralization remaining open and unconstrained to the north of Kakula West.

Regional geophysical surveys

The seismic survey to complete the final part of seismic transects toward the northern part of the area was completed early in Q3 2018. Vertical seismic profiles (VSPs), were completed down a number of boreholes during the quarter. VSPs are used to calibrate the seismic survey and facilitate a more accurate conversion of travel time of the seismic signal to depth below surface.

Ongoing upgrading work enables Mwadingusha power station to supply 32 megawatts of clean electricity to national grid

In January 2018, Ivanhoe announced that ongoing upgrading work at the Mwadingusha hydropower plant in the DRC had almost tripled the plant’s interim power output from 11 to 32 megawatts (MW). This represents 45% of the plant’s designed capacity. Three of Mwadingusha’s six generators now have been modernized. The remaining three generators are due to be upgraded and fully operational by the end of 2019 – restoring the plant to its installed output capacity of approximately 71 MW of power.

The work at Mwadingusha, part of a program to eventually overhaul and boost output from three hydropower plants, is being conducted by engineering firm Stucky, of Lausanne, Switzerland, under the direction of Ivanhoe Mines and its joint-venture partner, Zijin Mining, in conjunction with the DRC’s state-owned power company, La Société Nationale d’Electricité (SNEL). Once fully reconditioned, the three plants will have a combined installed capacity of approximately 200 MW of electricity for the national grid, which is expected to be more than sufficient for the Kamoa-Kakula Project.

The Kansoko Mine, Kakula Mine and Kamoa camp have been connected to the national hydroelectric power grid since the completion of a 12-kilometre, 120-kilovolt, dual-circuit power line between Kansoko and Kakula last December. The design of permanent, 11-kilovolt reticulation to the vent shafts and mine has started, which includes substations, overhead lines and surface cables.

Continued focus on community and sustainability

The Kamoa-Kakula Sustainable Livelihoods program is committed to sustainable development in the communities within the project’s footprint.

The main objective of the livelihoods program is to enhance food security and the living standards of the people who reside within the project’s footprint. The program is mainly implemented through fish farming and food crops, including farming of maize (corn) and vegetables, plus poultry production and beekeeping.

Additional, non-farming-related activities for Q3 2018 included education and literacy programs; the completion of a new school at the Muvunda village; a community water program; the continuation of the brick-making program; the creation of unskilled job opportunities; and the completion of the Kakula mine resettlement project.

4. Western Foreland Exploration Project
100%-owned by Ivanhoe Mines
Democratic Republic of Congo

Exploration continuing on Ivanhoe’s 100%-owned Western Foreland exploration licences west of Kamoa-Kakula

Ivanhoe’s DRC exploration group is targeting Kamoa-Kakula-style copper mineralization through a regional drilling program on its 100%-owned Western Foreland exploration licences, located to the north and west of the Kamoa-Kakula Project.

During Q3 2018, the team commissioned two extra rigs for its dry-season exploration drilling campaign. Three rigs began drilling north and west of Kamoa at the Kamilli, Mbali and Kiala targets, with one remaining at Makoko. A total of 8,895 metres in 17 diamond drill holes were completed during the quarter.

Four holes have been completed at Kiala and a further eight at Kamilli and Mbali. Detailed geological interpretation and assay results are pending. Drilling continued at Makoko throughout the quarter; 11 holes were completed.

Makoko Copper Discovery

On October 1, 2018, Ivanhoe announced the Makoko Copper Discovery on its 100%-owned Western Foreland Exploration licences, near Kamoa-Kakula in the DRC. The Makoko Discovery is Ivanhoe’s third major copper discovery in the DRC and shows characteristics identical to Ivanhoe’s tier-one Kamoa-Kakula Discoveries.

Selected drill holes at the Makoko Discovery include:

• DD004 (the Makoko discovery hole) intersected 3.94 metres (true width) of 5.46% copper, at a 2.0% copper cut-off, and 3.94 metres (true width) of 5.46% copper at a 1.0% copper cut-off, from a downhole depth of 306 metres.
• DD010 intersected 3.21 metres (true width) of 6.78% copper, at a 2.0% copper cut-off, and 3.95 metres (true width) of 5.81% copper at a 1.0% copper cut-off, from a downhole depth of 441 metres.
• DD017 intersected 3.19 metres (true width) of 6.49% copper at a 2.0% copper cut-off, and 4.64 metres (true width) of 4.88% copper, at a 1.0% copper cut-off, from a downhole depth of 471.7 metres.
• DD025 intersected 3.00 metres (true width) of 7.61% copper at a 2.0% copper cut-off, and 3.00 metres (true width) of 7.61% copper, at a 1.0% copper cut-off, from a downhole depth of 406 metres.
• DD046 intersected 7.44 metres (true width) of 7.81% copper at a 2.0% copper cut-off, and 9.39 metres (true width) of 6.51% copper, at a 1.0% copper cut-off, from a downhole depth of 523.51 metres.

The initial discovery hole at Makoko, DD004, was drilled in September 2017; follow-up and infill drilling has been ongoing since then. Drilling to date at Makoko has defined a flat-lying, near-surface stratiform copper deposit, similar to the Kamoa and Kakula deposits. The structure contour map indicates that the mineralized formation in the Makoko area is within 1,000 metres of surface. The majority of the drilling to date at Makoko has intersected the copper-rich zone between 400 metres and 800 metres below surface. The mineralized zone at Makoko strikes approximately south-southeast. It has been tested over a strike length of 4.5 kilometres and a dip extent of between one and two kilometres. Copper mineralization remains open both along strike and down dip.

The Grand Conglomerate unit (coarse-grained clastic sedimentary rock), the base of which hosts copper mineralization in the Western Foreland area, underlies the majority of the area covered by Ivanhoe’s exploration licences, with the base of the unit interpreted to be generally within 600 metres of surface.

At the nearby Kakula Discovery, the highest copper grades are associated with a siltstone-sandstone unit occurring within the Grand Conglomerate, located approximately one metre above the top of the Mwashia sandstone unit. Mineralization at Kakula consistently is bottom loaded, with grades increasing down-hole toward the contact between the host Grand Conglomerate and the underlying sandstone unit.

Copper mineralization at the Makoko Discovery similarly is located at the base of the Grand Conglomerate, just above the contact with the underlying Roan footwall rocks. This location is consistent with copper mineralization seen in earlier drilling into the Kakula Discovery and elsewhere in the Western Foreland area.

High-grade copper intersections at Makoko are associated with a rhythmically-banded, fine-grained siltstone-sandstone unit similar to the siltstone-hosted mineralization at Kakula, although at Makoko the host package of rocks also includes zones of reworked diamictite. The siltstone-rich zones appear to have been controlled by the underlying basin architecture at the time of deposition.

Sulphide copper mineralization generally is fine-grained and shows typical downward vertical zonation of chalcopyrite to bornite to chalcocite, similar to Kakula. The dominant copper sulphide mineral at Makoko tends to be bornite.

Selected quarterly financial information

The following table summarizes selected financial information for the prior eight quarters. Ivanhoe had no operating revenue in any financial reporting period and did not declare or pay any dividend or distribution in any financial reporting period.

Discussion of results of operations

Review of the three months ended September 30, 2018, vs. September 30, 2017

The company recorded a total comprehensive loss of $7.9 million for Q3 2018 compared to a total comprehensive loss of $21.2 million for the same period in 2017. Exploration and project expenditure for Q3 2018 amounted to $2.4 million and was $9.2 million less than for the same period in 2017 ($11.6 million). The decrease in exploration and project expenditure was the main reason for the decrease in the total comprehensive loss and is attributable to the capitalization of costs incurred at the Kipushi Project subsequent to the finalization of its PFS in December 2017.

With the focus at the Kipushi and Platreef projects being on development and the Kamoa-Kakula Project being accounted for as a joint venture, the total $2.4 million exploration and project expenditure in the three months ended September 30, 2018, related to exploration at Ivanhoe’s 100%-owned Western Foreland exploration licences. In Q3 2017, $10.8 million of the total $11.6 million exploration and project expenditure related to the Kipushi Project.

The company’s share of losses from the Kamoa Holding joint venture increased from $6.8 million in Q3 2017 to $7.8 million in Q3 2018. The following table summarizes the company’s share of the comprehensive loss from Kamoa Holding for the three months ended September 30, 2018, and for the same period in 2017:

The costs associated with mine development are capitalized as development costs in Kamoa Holding, while the exploration expenditure is expensed. Capitalization of costs at Kakula commenced during Q2 2017, coinciding with the start of the Kakula box cut. Expenditure attributable to exploration at Kamoa North, Kakula West and in the saddle area between Kakula West and Kakula still is expensed.

The interest expense in the Kamoa Holding joint venture relates to shareholder loans where each shareholder is required to fund Kamoa Holding in an amount equivalent to its proportionate shareholding interest. The company is advancing Crystal River’s portion on its behalf in return for an increase in the promissory note due to Ivanhoe.

Finance income for the three months ended September 30, 2018, amounted to $12.1 million, and was $4.1 million more than for the same period in 2017 ($8.0 million). The increase mainly was due to interest earned on loans to the Kamoa Holding joint venture to fund operations that amounted to $10.4 million in 2018, and increased by $3.3 million as the accumulated loan balance increased.

Review of the nine months ended September 30, 2018, vs. September 30, 2017

The company’s total comprehensive loss of $42.0 million for the nine months ended September 30, 2018, was $4.5 million higher than for the same period in 2017 ($37.5 million). The increased loss mainly was due to an exchange loss on translation of foreign operations of $23.9 million for the nine months ended September 30, 2018, resulting from the weakening of the South African Rand by 14% from December 31, 2017, to September 30, 2018, compared to an exchange gain on translation of foreign operations recognized in the same period of 2017 of $1.4 million.

Exploration and project expenditure for the nine months ended September 30, 2018, amounted to $6.6 million and was $22.9 million less than for the same period in 2017 ($29.5 million). Exploration and project expenditure for the nine months ended September 30, 2018, related to Ivanhoe’s 100%-owned Western Foreland exploration licences, while $28.4 million for the same period in 2017 related to the Kipushi Project.

Finance income for the nine months ended September 30, 2018, amounted to $33.4 million, and was $9.8 million more than for the same period in 2017 ($23.6 million). The increase mainly was due to interest earned on loans to the Kamoa Holding joint venture to fund operations that amounted to $28.7 million in 2018, and increased by $9.4 million as the accumulated loan balance increased.

The company’s share of losses from the Kamoa Holding joint venture increased to $21.7 million for the nine months ended September 30, 2018, from $17.3 million for the same period in 2017. The following table summarizes the company’s share of the comprehensive loss of Kamoa Holding for the nine months ended September 30, 2018, and for the same period in 2017:

Financial position as at September 30, 2018 vs. December 31, 2017

The company’s total assets increased by $576.4 million, from $1,271.3 million as at December 31, 2017, to $1,847.7 million as at September 30, 2018. The increase mainly was due to the proceeds received on completion of the equity investment by CITIC Metal Africa Investments Limited (CITIC Metal Africa) and Zijin exercising its anti-dilution rights, for gross proceeds of $555 million and $60 million respectively.

Cash and cash equivalents and short-term deposits increased by $358.1 million and $116.2 million respectively. The company utilized $8.3 million of its cash resources in its operations, which includes interest of $2.9 million received during the nine months ended September 30, 2018.

The company’s investment in the Kamoa Holding joint venture increased by $44.5 million from $552.4 million as at December 31, 2017, to $596.9 million as at September 30, 2018, with each of the current shareholders funding the operations equivalent to their proportionate shareholding interest. The company’s portion of the Kamoa Holding joint venture cash calls amounted to $37.4 million during the nine months ended September 30, 2018, while the company’s share of comprehensive loss from the joint venture amounted to $21.7 million.

The net increase of property, plant and equipment amounted to $64.1 million, with a total of $92.4 million being spent on project development and to acquire other property, plant and equipment. Of this total, $40.6 million and $50.9 million pertained to development costs and other acquisitions of property, plant and equipment at the Platreef Project and Kipushi Project respectively.

The main components of the additions to property, plant and equipment at the Platreef and Kipushi projects for the nine months ended September 30, 2018, and for the same period in 2017, are set out in the following table:

The company’s total liabilities increased by $1.3 million to $61.1 million as at September 30, 2018, from $59.8 million as at December 31, 2017.

Liquidity and capital resources

The company had $539.5 million in cash and cash equivalents and $116.2 million in short-term deposits as at September 30, 2018. At this date, the company had consolidated working capital of approximately $646.7 million, compared to $181.9 million at December 31, 2017.

On September 19, 2018, Ivanhoe announced the completion of a major strategic equity investment totalling C$723 million ($555 million) in Ivanhoe Mines by CITIC Metal Africa, a direct subsidiary of CITIC Metal Co., Ltd. (CITIC Metal), one of China’s leading international resources companies. Ivanhoe Mines issued 196,602,037 common shares to CITIC Metal Africa through a private placement at a price of C$3.68 per share. Zijin exercised its anti-dilution rights, generating additional proceeds for Ivanhoe of C$78 million ($60 million). The exercise by Zijin of its anti-dilution rights also was at a price of C$3.68 per share.

The Platreef Project’s restricted cash, which were funds of $290 million invested by the Japanese consortium of ITOCHU Corporation, Japan Oil, Gas and Metals National Corporation and Japan Gas Corporation, has been fully utilized and the project’s current expenditure is being funded solely by Ivanhoe as the Japanese consortium has elected not to contribute to current expenditures. Since the Platreef Project’s restricted cash was fully utilized, the company has contributed a total of $10.0 million on behalf of the Japanese consortium.

Since December 8, 2015, each shareholder in Kamoa Holding has been required to fund Kamoa Holding in an amount equivalent to its proportionate shareholding interest. The company is advancing Crystal River’s portion on its behalf in return for an increase in the promissory note due to Ivanhoe.

The company’s main objectives for 2018 at the Platreef Project are the continuation of Shaft 1 construction, securing a bulk-water supply and completion of early-works construction of Shaft 2. At Kipushi, the principal objectives are the completion of the feasibility study and continued upgrading of mining infrastructure. At the Kamoa-Kakula Project, priorities are the continuation of decline construction at Kakula and the completion of a PFS for Kakula. The company has budgeted to spend $13 million on further development at the Platreef Project; $25 million at the Kipushi Project; $3 million on regional exploration in the DRC; and $5 million on corporate overheads for Q4 2018 – as well as its proportionate funding of the Kamoa-Kakula Project, expected to be $32 million for Q4 2018.

The company has a mortgage bond outstanding on its offices in London, United Kingdom, of £3.2 million ($4.2 million). The bond is fully repayable on August 31, 2020, secured by the property and incurs interest at a rate of LIBOR plus 1.9% payable monthly in arrears. Only interest will be payable until maturity.

In 2013, the company became party to a loan payable to ITC Platinum Development Limited, which had a carrying value of $26.6 million as at September 30, 2018, and a contractual amount due of $32.2 million. The loan is repayable once the Platreef Project has residual cashflow, which is defined in the loan agreement as gross revenue generated by the Platreef Project, less all operating costs attributable thereto, including all mining development and operating costs. The loan attracts interest of LIBOR plus 2% calculated monthly in arrears. Interest is not capitalized. The difference of $5.6 million between the contractual amount due and the fair value of the loan is the benefit derived from the low-interest loan.

As well, all of the results of the pre-feasibility study of the Kamoa-Kakula Project and preliminary economic assessment of development options for the Kakula deposit, the feasibility study of the Platreef Project and the pre-feasibility study of the Kipushi Project, constitute forward-looking statements or information, and include future estimates of internal rates of return, net present value, future production, estimates of cash cost, proposed mining plans and methods, mine-life estimates, cash-flow forecasts, metal recoveries, estimates of capital and operating costs and the size and timing of phased development of the projects. Furthermore, with respect to this specific forward-looking information concerning the development of the Kamoa-Kakula, Platreef and Kipushi projects, the company has based its assumptions and analysis on certain factors that are inherently uncertain. Uncertainties include: (i) the adequacy of infrastructure; (ii) geological characteristics; (iii) metallurgical characteristics of the mineralization; (iv) the ability to develop adequate processing capacity; (v) the price of copper, nickel, zinc, platinum, palladium, rhodium and gold; (vi) the availability of equipment and facilities necessary to complete development; (vii) the cost of consumables and mining and processing equipment; (viii) unforeseen technological and engineering problems; (ix) accidents or acts of sabotage or terrorism; (x) currency fluctuations; (xi) changes in regulations; (xii) the compliance by joint-venture partners with terms of agreements; (xiii) the availability and productivity of skilled labour; (xiv) the regulation of the mining industry by various governmental agencies; and (xv) political factors.

This release also contains references to estimates of Mineral Resources and Mineral Reserves. The estimation of Mineral Resources is inherently uncertain and involves subjective judgments about many relevant factors. Estimates of Mineral Reserves provide more certainty but still involve similar subjective judgments. 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 estimated future production from the company’s projects, the anticipated tonnages and grades that will be mined and the estimated level of recovery that will be realized), which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that ultimately may prove to be inaccurate. Mineral Resource or Mineral Reserve estimates may have to be re-estimated based on: (i) fluctuations in copper, nickel, zinc, platinum group elements (PGE), gold or other mineral prices; (ii) results of drilling; (iii) metallurgical testing and other studies; (iv) proposed mining operations, including dilution; (v) the evaluation of mine plans subsequent to the date of any estimates and/or changes in mine plans; (vi) the possible failure to receive required permits, approvals and licences; and (vii) changes in law or regulation.

Forward-looking statements and information involve significant risks and uncertainties, should not be read as guarantees of future performance or results and will not necessarily be accurate indicators of whether or not such results will be achieved. A number of factors could cause actual results to differ materially from the results discussed in the forward-looking statements or information, including, but not limited to, the factors discussed below and under the “Risk Factors” section and elsewhere in the company’s Q3 2018 Financial Statements and Management’s Discussion and Analysis, as well as unexpected changes in laws, rules or regulations, or their enforcement by applicable authorities; the failure of parties to contracts with the company to perform as agreed; social or labour unrest; changes in commodity prices; and the failure of exploration programs or studies to deliver anticipated results or results that would justify and support continued exploration, studies, development or operations.

Although the forward-looking statements contained in this release are based upon what management of the company believes are reasonable assumptions, the company cannot assure investors that actual results will be consistent with these forward-looking statements. These forward-looking statements are made as of the date of this release and are expressly qualified in their entirety by this cautionary statement. Subject to applicable securities laws, the company does not assume any obligation to update or revise the forward-looking statements contained herein to reflect events or circumstances occurring after the date of this release.

The company’s actual results could differ materially from those anticipated in these forward-looking statements as a result of the factors set forth in the “Risk Factors” section and elsewhere in the company’s Q3 2018 Financial Statements and Management’s Discussion and Analysis.
