Ivanhoe Mines (TSX:IVN) Executive Chairman Robert Friedland and Chief Executive
Officer Lars-Eric Johansson today announced the start of construction on the box
cut for the initial portal to planned decline ramps that will provide
underground access to the proposed Kamoa copper mine in the Democratic Republic
of Congo's Katanga province.


A contract for construction of the box cut was awarded to Lubumbashi-based
Mining Company Katanga Sprl (MCK), which has extensive local experience in
contract mining and earthworks and has worked on other significant Katanga
copper mining projects, including Kinsevere, Kipoi and Kolwezi.


Construction of the box cut is expected take approximately five months, after
which development of the first set of twin declines can commence. The declines
have been designed to intersect the high-grade copper mineralization in Kansoko
Sud area, approximately 150 metres below surface. Ivanhoe's drilling program in
this area has defined a thick, near-surface zone of high-grade copper
mineralization in Kansoko Sud, where a recent drill hole, 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.


"This first development step is an important milestone in Ivanhoe's schedule to
begin realizing the tremendous potential of Kamoa's high-grade resource to
deliver meaningful benefits to all of our stakeholders," said Mr. Friedland.


"Industry experts recognize that Kamoa is a world-class copper deposit, both in
terms of size and grade. In our mine planning, Kamoa's tabular form and
relatively undeformed geometry, allows utilization of simple and low-cost mining
methods; no complex metallurgical processes are required and the inherent
scalability of the deposit means that it can provide significant returns over a
range of production scenarios."


Kamoa is the world's largest high-grade (greater than 2.5% Cu) copper resource.
As such, Ivanhoe's initial, independent preliminary economic assessment (PEA)
was based on an initial mining rate of three million tonnes per annum (Mtpa),
which could be scaled up in phases to a steady state rate of up to 15 Mtpa.


Mr. Johansson said it is important for Ivanhoe to strike the correct balance
between capital efficiency and operational risk.


"This principle will be adopted during the project's first phase, which is being
scoped to target several high-grade areas in Kansoko Sud in the initial build
up. The approach is to target early cash-generation opportunities, while
allowing organizational learning and operational refinements to be incorporated
into the subsequent expansion phases," Mr. Johansson added.

Underground mining to use mechanized room-and-pillar and drift-and-fill methods

Given the favourable geological characteristics of the Kamoa Deposit as derived
from the December 2012 mineral resource - including its relatively undeformed,
continuous mineralization - it is considered amenable to large-scale,
mechanized, room-and-pillar and drift-and-fill mining. The overall dip and
geometry of the resource make it conducive to room-and-pillar mining in the
shallow portions of the deposit, which will transition to drift-and-fill mining
in the deeper or steeper sections. These methods are the accepted industry
standards for mining deposits such as Kamoa.


Infill drilling of the planned initial mining area from the PEA has confirmed
the overall grade and thickness of the December 2012 resource estimate in these
areas and provided invaluable refinement within localized areas. While
traditionally modelled on a 1% total copper cut-off to define a selective
mineralized zone (SMZ), the deposit has shown that grade continuity also exists
at an elevated 1.5% total copper vertical cut-off, and that a 2.0% total copper
vertical cut-off may be feasible in certain areas. Applying higher cut-offs in
defining the SMZ will allow for implementation of higher-grade, narrower mining
options which should improve overall mine economics. Defining the SMZ at higher
vertical cut-offs also has created more expansive, contiguous zones of
high-grade mineralization.


Progress on pre-feasibility study, with initial development planned 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 (3 Mtpa) mine and
concentrator. Development plans will be refined following completion of the PFS.


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 3 Mtpa 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.

Cautionary statement on forward-looking information

Certain statements in this release constitute "forward-looking statements" or
"forward-looking information" within the meaning of applicable securities
laws.Such statements involve known and unknown risks, uncertainties and other
factors which may cause the actual results, performance or achievements of the
company, or industry results, to be materially different from any future
results, performance or achievements expressed or implied by such
forward-looking statements or information. Such statements can be identified by
the use of words such as "may", "would", "could", "will", "intend", "expect",
"believe", "plan", "anticipate", "estimate", "scheduled", "forecast", "predict"
and other similar terminology, or state that certain actions, events or results
"may", "could", "would", "might" or "will" be taken, occur or be achieved. These
statements reflect the company's current expectations regarding future events,
performance and results and speak only as of the date of this release.


Forward looking statements in this release include, but are not limited to:
statements regarding the timing and results of a pre-feasibility study at the
Kamoa Project; statements regarding the expected time it will take for
construction of the box cut; statements regarding the expectation that the
development of the first set of twin declines is expected to begin upon
completion of the box cut; statements regarding the declines have been designed
to intersect the high-grade copper mineralization in the Kansoko Sud mining
area, approximately 150 metres below surface; statements regarding underground
mining to use mechanized room-and-pillar and drift-and-fill methods. 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) 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 availability and productivity of skilled labour; (xiii) the regulation
of the mining industry by various governmental agencies; and (xiv) political
factors.


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 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 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 below and under "Risk Factors", 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 most recent Management's
Discussion and Analysis report and Annual Information Form, available at
