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.

As well, the results of the preliminary economic assessment of
the Kamoa Project constitute forward-looking information, including
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, and estimates of capital and operating costs.
Furthermore, with respect to this specific forward-looking
information concerning the development of the Kamoa Project, the
company has based its assumptions and analysis on certain factors
that are inherently uncertain. Uncertainties include among others:
(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; (vi) the availability of
equipment and facilities necessary to complete development, (vii)

This release also contains references to estimates of Mineral
Resources. The estimation of Mineral Resources is inherently
uncertain and involves subjective judgments about many relevant
factors. 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 Kamoa Project, 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 may ultimately prove to be inaccurate.
Mineral Resource estimates may have to be re-estimated based on:
(i) fluctuations in copper price; (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 (vi) the possible
failure to receive required permits, approvals and licenses.
Forward-looking
statements 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, including, but not limited to, the
factors discussed here, 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.
