Ivanhoe Mines announces that Kakula now contains Indicated Resources of 116 million tonnes at 6.09 copper, plus Inferred Resources of 12 million tonnes at 4.45% copper, at a 3% cut-off

KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO--(Marketwired - May 17, 2017) - Robert Friedland, Executive Chairman of Ivanhoe Mines (TSX:IVN)(OTCQX:IVPAF), and Lars-Eric Johansson, Chief Executive Officer, announced today that the company has completed an independently verified, updated Mineral Resource estimate for the extremely-high-grade Kakula Discovery on the tier one Kamoa-Kakula Copper Project, near the mining centre of Kolwezi in the Democratic Republic of Congo (DRC). The Kamoa-Kakula Project is a joint venture between Ivanhoe Mines, Zijin Mining and the government of the Democratic Republic of Congo.

The new Mineral Resource estimate covers a strike length of approximately 7.7 kilometres along the eastern section of the Kakula Discovery. It boosts the tonnage of Kakula's estimated Indicated Resources by 75% compared to the October 2016 resource estimate - which covered a strike length of 4.1 kilometres.

Kakula's Indicated Resources increased by 50 million tonnes, to the current total of 116 million tonnes at 6.09% copper, at a 3% cut-off grade. This compares to 66 million tonnes at 6.59% copper estimated in October 2016, also at a 3% cut-off grade.

Kakula's new estimated Inferred Resources are an additional 12 million tonnes at 4.45% copper, at a 3% cut-off.

"With 12 rigs currently drilling at Kakula and Kakula West and another two rigs about to begin testing important new targets on the licence area, Kakula is an international story of discovery that has earned the mining world's attention," said Mr. Friedland.

"To keep the mine-planning process driving forward, we need to provide the mining engineers with updated resource numbers for the expanded-case preliminary economic assessment due to be issued in the third quarter."

Mr. Johansson said that the copper grades at Kakula are significantly higher than the average grades found at the adjacent, earlier Kamoa Discovery. "We're highly confident that fast-tracking mine development at Kakula will have a profound, positive impact on the economics of the overall Kamoa-Kakula Project.

"Kakula alone already has enough resources, grading 6% copper or higher, to maintain approximately 20 years of mining at a rate of six million tonnes per year. We're also confident that Kakula West has similar potential."

The new Kakula resource estimate covers approximately two thirds of the known strike extent of the high-grade, chalcocite-rich Kakula trend, which now is approaching 12 kilometres, and remains open along strike in both directions.

Kamoa-Kakula geologists now are planning for a resource estimate at the newly discovered Kakula West area, located approximately three kilometres west of the new Kakula resource boundary. Excellent visual drill intercepts at Kakula West show a rapidly expanding area of shallow copper mineralization characterized by finely disseminated chalcocite in siltstone and maroon diamictite. The style and the overall geometry of mineralization at Kakula West are typical of the high-grade Kakula trend to the east.

The Kakula Discovery is approximately 10 kilometres southwest of Kamoa's initial Kansoko Mine development. Ivanhoe and Zijin have been conducting an aggressive drilling program at the Kakula Discovery since April 2016. More than 85,000 metres of drilling have been completed. Given the outstanding success to date in delineating high-grade copper resources, the Kakula drilling program is expected to continue throughout 2017.

Nearly 200 square kilometres of the approximately 400-square-kilometre Kamoa-Kakula Project area remain untested. The Kamoa-Kakula geology team, with the assistance of its technical advisors, has intensively evaluated the structural and stratigraphic controls on mineralization of the broader Kamoa-Kakula basin. This work has highlighted at least nine high-priority targets located in the untested areas of the Kamoa-Kakula Project that are planned to be drill tested this year.

"The potential exists to find another Kakula. Or perhaps something even better," Mr. Friedland said.

The Kakula Mineral Resource estimate was prepared by Ivanhoe Mines under the direction of Dr. Harry Parker and Gordon Seibel, both RM SME, of Amec Foster Wheeler, of Reno, Nevada, in accordance with the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. Dr. Parker and Mr. Seibel are the Qualified Persons for the estimate, which has an effective date of May 16, 2017.

Highlights include:

• Indicated Mineral Resources total 349 million tonnes at a grade of 3.23% copper, containing 24.9 billion pounds of copper at a 1% copper cut-off. At a 2% copper cut-off, Indicated Mineral Resources total 210 million tonnes at a 4.41% copper grade, containing 20.4 billion pounds of copper. At a higher cut-off of 3% copper, Indicated Mineral Resources total 116 million tonnes at a grade of 6.09% copper, containing 15.6 billion pounds of copper.
  
  
• Inferred Mineral Resources total 59 million tonnes at a grade of 2.26% copper, containing 3.0 billion pounds of copper at a 1% copper cut-off. At a 2% copper cut-off, Inferred Mineral Resources total 27 million tonnes at a 3.19% copper grade, containing 1.9 billion pounds of copper. At a higher cut-off of 3% copper, Inferred Mineral Resources total 12 million tonnes at a grade of 4.45% copper, containing 1.1 billion pounds of copper.
  
  
• The average true thickness of the selective mineralized zone (SMZ) at a 1% cut-off is 12.0 metres in the Indicated Mineral Resources area and 6.4 metres in the Inferred Mineral Resources area. At a higher 3% cut-off, the average true thickness of the SMZ is 5.3 metres in the Indicated Mineral Resources area and 3.9 metres in the Inferred Mineral Resources area.
  
  

A technical report on the new resource estimate will be filed on SEDAR at www.sedar.com and on the Ivanhoe Mines website at www.ivanhoemines.com within 45 days of the issuance of this news release.

The Kakula Mineral Resources are defined within an area covering a total area of 12.8 square kilometres at a 1% copper cut-off. The total areal extent of Indicated Mineral Resources is 9.8 square kilometres at a 1% copper cut-off and the areal extent of the Inferred Mineral Resources is 3.0 square kilometres at a 1% cut-off. The average dip of the mineralized zone in the Indicated Resources area is 15 degrees, while the average dip is 18 degrees in the Inferred Mineral Resources area.

The Kakula Discovery remains open for significant expansion along trend to the west and the southeast, while the remainder of the southern parts of the Kamoa-Kakula mining licence area remains virtually untested (see figures 2 and 3). Twelve rigs now are drilling in the Kakula Discovery Area and more than 25,000 metres have been drilled at Kakula since the start of the year.

The May 2017 Kakula Mineral Resource estimate is based on the results from approximately 61,400 metres of drilling in 121 holes. The May 2017 estimate includes drill holes completed by April 18, 2017 in the eastern section of the high-grade, chalcocite-rich Kakula trend; it does not include any holes drilled in the new Kakula West Discovery area. The October 2016 Kakula Mineral Resource estimate was based on results from approximately 24,000 metres of drilling in 65 holes.

Indicated Resources are defined when the drill-hole spacing approximates a 400-metre grid, while Inferred Resources are defined when the drill-hole spacing approximates an 800-metre grid.

The May 2017 Kakula Mineral Resource estimate was prepared by Ivanhoe Mines under the direction of Dr. Harry Parker and Gordon Seibel, both RM SME, of Amec Foster Wheeler. Dr. Parker and Mr. Seibel are the Qualified Persons for the estimate, which has an effective date of May 16, 2017. A technical report will be filed on SEDAR at www.sedar.com and on the Ivanhoe Mines website at www.ivanhoemines.com within 45 days of the issuance of this news release.

The May 2017 Kakula Mineral Resources, along with sensitivities at various cut-offs, are shown in tables 1, 2 and 3.

Notes:

1. Ivanhoe's Mineral Resources Manager George Gilchrist, a Member of the Geology Society of South Africa and Professional Natural Scientist (Pr. Sci. Nat) with the South African Council for Natural Scientific Professions (SACNASP), estimated the Mineral Resources under the supervision of Dr. Harry Parker and Gordon Seibel, both RM SME, who are the Qualified Persons for the Mineral Resources. The effective date of the estimate is May 16, 2017. Mineral Resources are estimated using the CIM Definition Standards for Mineral Resources and Reserves (2014).
   
   
2. For Kakula, Mineral Resources are reported using a total copper (TCu) cut-off grade of 1% TCu and an approximate minimum thickness of 3 metres. A 1% TCu cut-off is a natural cut-off grade on the Central African Copperbelt. There are reasonable prospects for eventual economic extraction under assumptions of a copper price of US$3.00/lb, employment of underground, mechanized, room-and-pillar and drift-and-fill mining methods, and that copper concentrates will be produced and sold to a smelter. Mining costs are assumed to be $38/t. Concentrator and General and Administrative (G&A) costs are assumed to be $19/t. Metallurgical recovery is assumed to be 77% at the 1% TCu cut-off and 88% at the average grade of the Mineral Resource. Ivanhoe is studying (preliminary economic assessment in progress) reducing mining costs using a convergence backfill method.
   
   
3. Reported Mineral Resources contain no allowances for hanging wall or footwall contact boundary loss and dilution. No mining recovery has been applied.
   
   
4. Rounding as required by reporting guidelines may result in apparent differences between tonnes, grade and contained metal content.

High-grade Kakula Discovery presents transformational opportunities for Kamoa-Kakula development

Mineralization at Kakula is substantively thicker and higher grade than elsewhere on the Kamoa mining licence; it also is consistently bottom-loaded and will support the construction of selective mineralized zone (SMZ) composites at cut-offs up to at least 3% copper. The lateral consistency of mineralization at these higher cut-offs presents significant opportunities for mine planning, with large areas of the resource having average grades in excess of 6% when using the a SMZ at a cut-off of 3% copper.

The Kakula resource model was constructed using a series of nested grade shells at 1%, 2% and 3% cut-offs. A minimum thickness of approximately 3.0 metres was applied to the 3% grade shell and the outer shells were nested above and below this central shell. The resultant model allows the flexibility to show distribution of grades and thicknesses across the various grade shells and highlight Kakula's outstanding, high-grade potential.

Figures 4 and 5, below, show the distribution of grades across the 3% copper shell and the base-case 1% copper shell, respectively.

Kakula West rapidly emerging as another shallow, high-grade discovery

In March 2017, Ivanhoe announced that a new step-out hole - drilled 3.0 kilometres west of the boundary of Kakula's May 2017 Inferred Resources - intersected a relatively shallow, 16.3-metre (true width) zone of typical Kakula-style, chalcocite-rich copper mineralization similar to holes drilled in the centre of the eastern portion of the Kakula Deposit. Assays for the discovery hole - DD1124 - confirmed the high-grade discovery with assays of 5.83% copper over 8.86 metres (true width) at a 2.5% cut-off, including a 6.14-metre (true width) interval at 6.84% copper.

Subsequent drilling in and around DD1124, including DD1138 and DD1144, which both intersected relatively shallow, Kakula-style, chalcocite-rich copper mineralization, has extended the Kakula West mineralized zone to a length of more than one kilometre and a width of approximately 850 metres. The zone still is open in multiple directions. The style of copper mineralization and geometry of the high-grade zone is showing similar characteristics to the profile across the Kakula main trend to the east. Visual results show a rapidly expanding area of shallow mineralization characterized by finely disseminated chalcocite in siltstone and maroon diamictite.

The Kamoa-Kakula geological team is focused on the logging and processing of drill core from recent Kakula West drill holes now that the core processing and assaying have been completed for the drill holes that comprised the May 2017 Mineral Resource estimate.

Three of the 12 rigs currently drilling at Kakula are drilling in the Kakula West discovery area; five rigs are extending the western limit of the currently defined Kakula Resource area; two rigs are drilling expansion holes in the southeast; and two drill rigs will begin drilling infill holes between Kakula West and the Kakula Deposit.

Kakula's updated resources add to an already tier one resource base at the Kamoa-Kakula Project

Kakula is the second major discovery on the Kamoa mining licence in the past nine years. The Kamoa Deposit, which was announced as a major new discovery in 2009, is now under initial development with twin declines nearing completion at the Kansoko Mine. An independent prefeasibility study was completed on the Kamoa Deposit in February 2016 and is the basis of Kamoa's current mineral reserve for the Kansoko Mine.

The combined Kamoa-Kakula Indicated Mineral Resources now total 1.10 billion tonnes grading 2.85% copper, containing 69.1 billion pounds of copper at a 1.0% copper cut-off grade and a minimum thickness of approximately three metres.

At a higher 1.4% copper cut-off grade and a minimum thickness of three metres, the combined Kamoa-Kakula Indicated Mineral Resources now total approximately one billion tonnes grading 3.02% copper, containing approximately 66 billion pounds of copper.

Kamoa-Kakula now also has Inferred Mineral Resources of approximately 191 million tonnes grading 2.37% copper and containing 10.0 billion pounds of copper, also at a 1.4% copper cut-off grade and an approximate minimum thickness of three metres.

The total consolidated Mineral Resource for the Kamoa-Kakula Project is shown in Table 4 and the sensitivity of the resource at various cut-offs is shown in Table 5.

Kamoa-Kakula now ranks as one of the world's five largest copper deposits

The May 2017 Kakula estimate firmly establishes the Kamoa-Kakula Project in the ranks of the five largest copper deposits in the world - and its copper grades are the highest, by a wide margin, of the copper world's top 10 deposits (see Figure 7). Significantly, both the Kakula Discovery and the earlier Kamoa Discovery continue to remain open for expansion.

Research by Wood Mackenzie also shows that the Kamoa-Kakula Project's distinctions include the world's largest, high-grade (>2.5% copper grade) copper deposit and the world's largest, undeveloped copper deposit, based on contained copper in the project's Measured and Indicated Mineral Resources.

Revised preliminary economic assessment underway for two six-million-tonne-per-year mines -- one at Kamoa's Kansoko Sud and one at Kakula

Following completion of the revised Kakula Mineral Resource estimate, Kamoa Copper has retained OreWin Pty. Ltd., of Australia, to prepare a follow-up preliminary economic assessment (PEA) for the development of the Kakula and Kamoa deposits.

The new PEA will be based on the May 2017 Mineral Resource estimate. It is expected that the increased resource base at Kakula will support a mine capacity of approximately six million tonnes per annum (Mtpa). The Kansoko Mine capacity also is expected to be six Mtpa, giving the revised PEA a projected peak mine production of approximately 12 Mtpa from the presently delineated Kamoa and Kakula deposits. In light of the successful step-out drilling at Kakula West, as well as the potential to find additional resources in high-priority targets located in the untested parts of the Kamoa-Kakula Project area, the Kamoa-Kakula development plans will be reassessed and amended as the project advances.

The PEA also will analyze process facilities, mining planning and scheduling, including capital costs and operating costs for both mining and concentrator operations. The PEA will draw on recommendations from the Kamoa 2016 pre-feasibility study and the Kamoa-Kakula PEA issued in December 2016.

Kakula mineralization is characteristically bottom loaded. The resource estimate demonstrates that opportunities exist to mine Kakula at much higher lateral and vertical cut-offs than at Kamoa's Kansoko Sud. The clear zonation and grades in the central high-grade core should provide sequencing opportunities to mine at significantly elevated grades.

To help advance the mine-planning work at Kakula, the Kamoa technical team is proceeding with the construction of a box cut at Kakula to accommodate decline ramps that will provide underground access to the deposit.
