Ivanhoe Mines Updates Ongoing Exploration and Development Work at Its Kamoa Copper Discovery in the Democratic Republic of Congo's Southern Province of Katanga

Recent drill hole intercepted 15.7 metres true thickness of 7.04% copper in Kansoko Sud high-grade area that will be the focus of initial mining

LUBUMBASHI, DEMOCRATIC REPUBLIC OF CONGO--(Marketwired - May 13, 2014) - Robert Friedland, Executive Chairman of Ivanhoe Mines (TSX:IVN), and Lars-Eric Johansson, Chief Executive Officer, today issued a summary of significant, ongoing exploration and development activities at the company's Tier 1 Kamoa copper discovery, near the mining centre of Kolwezi in the Democratic Republic of Congo's southern province of Katanga.

Mr. Friedland said the work has further confirmed that the focus of the company's initial mine development at Kamoa will be on the high-grade Kansoko Sud area, where ongoing infill drilling since the last resource estimate was produced in 2012 has defined a thick, near-surface zone of high-grade copper sulphide mineralization that would be amenable to treatment by a conventional copper flotation plant.

One of the 101 infill holes drilled in this area, for which assays were received in April 2014, intercepted 15.7 metres (true width) of 7.04% copper at a 1.5% total copper cut-off.

Infill drilling confirms overall grade and thickness of 2012 resource estimate

Since issuing an updated, independent preliminary economic assessment (PEA) for the Kamoa Project in November 2013, Ivanhoe has concentrated its exploration drilling activities on the acquisition of samples for metallurgical testing, as well as undertaking drilling on 200-metre close-spaced sections in the Kansoko Sud area. Exploration drilling has been directed at infilling those areas identified as primary mining targets in the PEA.

A total of 60 of the 101 holes with assays returned since the release of the updated PEA six months ago were drilled in the Kansoko Sud area, 29 were in Kansoko Centrale, one in Kansoko Nord, nine in Kamoa Sud and two in Makalu. The final composited assay results are included at the end of this news release.

Infill drilling of the initial mining area has confirmed the overall grade and thickness of the December 2012 resource estimate in these areas and has provided invaluable refinement within localized areas. While traditionally modelled on a 1% total copper cut-off to define a selective mineralized zone, the deposit has shown that grade continuity also exists at an elevated 1.5% total copper vertical cut-off, and that a 2.0% vertical total copper cut-off may be feasible in certain areas.

Initial mine economics should benefit from narrower, higher-grade intervals

Recent work defining the selective mineralized zone (SMZ) at higher vertical cut-offs has shown that narrower, higher-grade intervals create more expansive, contiguous zones, which should improve initial mine economics.

A new base case for future engineering studies is being developed using a 1.5% total copper cut-off with a minimum three-metre mining height and a maximum mining constraint of six metres (a single mining cut); incremental mineralization above six metres will be included only if the grade of the incremental mineralization exceeds 2%. This approach was introduced for thicker intercepts, to ensure initial mining cuts would extract only higher-grade material.

Encouraging results of Kansoko Sud infill drilling and Hole DKMC DD860

The initial mine plan produced in the PEA focused initial mining in the shallower portion of Kansoko Sud, an area previously drilled on 400-metre spacings. Since completion of the PEA, Ivanhoe has concentrated on substantially closing the distances to 100-metre spacings on 200-metre-spaced, east-west lines, with the goal of demonstrating grade and structural continuity of this high-grade zone at potentially elevated cut-offs. Drilling is continuing in this area; results to date are extremely encouraging and have confirmed - and in some locations exceeded - the initial results based on holes spaced 400 metres apart.

Included in the new drill results is Hole DD860, which is a PQ-sized parent hole of a series of wedges drilled for comminution. Assay results received for Hole DD860 show a remarkable combination of grade and thickness, with a copper grade of 6.88% over 17.3 metres (16.2 metres true thickness) at a 1% total copper composite cut-off. Using a higher cut-off of 1.5% total copper, the intercept returned 7.04% total copper over 16.8 metres (15.7 metres true thickness). Sections through Hole 860 displayed good continuity of grade and thickness in the north-south and east-west orientations, as shown in the accompanying sections - which also report the elevated, 1.5% total copper composites.

Exploration continuing in 2014

During the remainder of 2014, Ivanhoe intends to continue its detailed infill program in the initial mining area to cover an area of approximately one square kilometre with a 100-metre detailed grid.

Progress on pre-feasibility study, with initial mining at Kansoko Sud

In line with the phased approach to project development outlined in the 2013 updated Kamoa PEA, the Kamoa pre-feasibility study (PFS) is progressing on the basis of an initial three-million-tonne-per-annum (3Mtpa) mine and concentrator.

Reviews of the resource model, combined with results from recent infill drilling at Kansoko Sud, have confirmed grade continuity, which allows the resource model to be constrained at a higher cut-off grade. The focus in planning the early years of mine production continues to be on the near-surface and high-grade material from Kansoko Sud to maximize margins. The 3Mpta mine and concentrator can be split into modules to potentially better match the underground ramp-up and further reduce the pre-production development capital. This will be examined in more detail as part of the pre-feasibility study to provide flexibility to the development of the Kamoa Project.

Work to begin this year on decline to access the Kamoa underground

Preparations are underway to start the first mine-access decline at Kamoa's Kansoko Sud area. The decline is designed to provide access to the high-grade copper resources that would be targeted for the planned first phase of production using the room-and-pillar mining method.

Large-scale underground mining to use room-and-pillar and drift-and-fill methods

Kamoa is considered amenable to large-scale, mechanized mining using a combination of room-and-pillar and drift-and-fill methods, given the deposit's favourable mining characteristics as derived from the December 2012 mineral resource - including its relatively undeformed, continuous mineralization, local continuity between closely-spaced drill holes and flat-to-moderate dips. The low dip and the flat geometry of the resource make it conducive to room-and-pillar mining in the shallow portions of the deposit, which would transition to drift-and-fill mining in the deeper sections. These conventional mining methods are the accepted industry standards for deposits such as Kamoa.

A minimum mining thickness of 3.5 metres was used for the PEA; any thinner blocks were diluted to 3.5 metres using the average grade of the adjacent hanging wall and footwall blocks. Room-and-pillar panels are designed to be 80 metres wide and 500 metres long, with in-panel extraction ratios ranging from 60% to 80%, depending on the panel depth below surface. Partial extraction of the barrier pillars (up to 50%) is planned at the end of the mining of each section.

The overall extraction ratio in the room-and-pillar areas is expected to be between 56% and 82%, depending on the depth below surface. Higher in-panel extraction ratios of up to 95% are expected within the drift-and-fill areas, with an overall extraction ratio of 85% after partial extraction of barrier pillars.

Kamoa Project description

The Kamoa Project is a newly discovered, very large, stratiform copper deposit with adjacent prospective exploration areas within the Central African Copperbelt, approximately 25 kilometres west of the town of Kolwezi and about 270 kilometres west of the provincial capital of Lubumbashi. Ivanhoe Mines holds its 95% interest in the Kamoa Project through a subsidiary company, Kamoa Copper SPRL. A 5%, non-dilutable interest in Kamoa Copper SPRL was transferred to the DRC government on September 11, 2012, for no consideration, pursuant to the DRC Mining Code. Ivanhoe also has offered to sell an additional 15% interest to the DRC on commercial terms, to be negotiated.

In December 2012, a new, independent mineral resource estimate was prepared for the Kamoa Copper Discovery by AMEC E&C Services, of Reno, Nevada. The new estimate ranked Kamoa as Africa's largest, high-grade copper discovery and the world's largest, undeveloped high-grade copper discovery.

As of January 2013, Ivanhoe Mines had discovered Indicated Mineral Resources of 739 million tonnes grading 2.67% copper, containing 43.5 billion pounds of copper, and Inferred Mineral Resources of 227 million tonnes grading 1.96% copper, containing 9.8 billion pounds of copper. A 1% copper cut-off grade and a minimum vertical mining thickness of three metres were applied in each classification.

Kamoa Mineral Resources December 2012

Copper cut-off	Tonnage (Mt)	Copper Grade	Contained Copper (billion lbs)
Indicated Resource
3.00%	224	3.85%	19.0
2.00%	550	3.04%	36.9
1.00%	739	2.67%	43.5
Inferred Resource
3.00%	19	3.40%	1.4
2.00%	93	2.64%	5.4
1.00%	227	1.96%	9.8

Note: Mineral Resources have an effective date of December 10, 2012. Harry M. Parker and Gordon Seibel, both SME Registered Members, are the Qualified Persons responsible for the Mineral Resource estimate, which was prepared by Mr. Seibel. Mineral Resources are reported using a total copper cut-off grade of 1% copper and a minimum assumed mining thickness of three metres. A 1% copper cut-off grade is typical of analogue deposits in neighbouring Zambia.
