NOTE 9 - PROPERTY, PLANT AND EQUIPMENT, PAGE 78
- -----------------------------------------------

PLEASE  PRESENT THE KEY  ARGUMENTS AS TO WHY YOU BELIEVE THAT THE  EXPENDITURES
IDENTIFIED  IN NOTE 9  RELATING  TO THE  EXPLORATION  SHAFT  (CAPITAL  WORKS IN
PROGRESS  AT  DECEMBER  31,  2005  CONSISTED  MAINLY OF  SURFACE  ASSETS  BEING
CONSTRUCTED FOR THE EXPLORATION  SHAFT AT OYU TOLGOI ($21.4 MILLION)) SHOULD BE
CAPITALIZED. IN FORMULATING YOUR RESPONSE PLEASE REFER TO SEC INDUSTRY GUIDE 7,
WHICH PROVIDES GUIDANCE ON THE CAPITALIZATION OF EXPLORATION EXPENDITURES.

RESPONSE
- --------

Ivanhoe Mines has been exploring the Oyu Tolgoi  properties  since May 2000. In
2002,  Ivanhoe Mines  exercised its earn-in right to acquire a 100% interest in
the Oyu Tolgoi  project from BHP  Minerals  International  Exploration  Inc. In
December  2003,  Ivanhoe  Mines  converted  its 4  exploration  licenses on the
properties into 60 year mining licenses,  which are renewable for an additional
40 years.

From  2000 to 2005,  the  Company  has  expensed  exploration  expenditures  of
approximately  $293 million.  These  expenditures  primarily consist of payroll
expenses, contractor costs, drilling expenditures and camp costs.

Property,  plant and equipment acquired from May 2000 onward including moveable
equipment, were capitalized where the equipment had an alternative use.

In September 2005 the Company issued its  Integrated  Development  Plan ("IDP")
which outlined the framework for the  development  of the project.  The project
consists of two deposit  groups,  called the Southern Oyu Deposits and the Hugo
Dummett North and South Deposits. The IDP schedules development to occur over a
15-year period,  providing for an ultimate mine life that is expected to exceed
40 years.

The IDP consisted of:

    1.  a feasibility-level  evaluation of an initial,  large open-pit mine
        developed on the near-surface Southern Oyu deposits; and

    2.  pre-feasibility  and  scoping-level  evaluations  of the associated
        infrastructure,  such  as  power  supply,  and  of  an  underground
        block-cave  mining  operation at the Hugo  Dummett  North and South
        deposits.

During the second half of 2005, Ivanhoe Mines commenced  constructing Shaft No.
1. In certain  disclosure  documents  Ivanhoe Mines has made  reference to this
shaft as the Exploration Shaft, mainly to differentiate it from Shaft No. 2, or
the Production  Shaft.  These terms are used  internally for ease of reference;
however,  the current  plan for  development  would result in both shafts being
used in the exploration, development, construction and production stages of the
Oyu Tolgoi mine.  This shaft will be 1,340 meters in depth once  completed  and
will be used for  drilling  of the  underground  deposits  in order to quantify
reserves.  The Company  estimates  that the cost to  construct  Shaft 1 will be
approximately  $135 million,  consisting of  approximately  $30 million for the
shaft surface assets and $105 million for the below surface costs.

The surface assets include the Head Frame, control room, hoisting equipment and
ancillary  facilities.  The surface  assets were  considered  capital  works in
progress at December 31, 2005 and became available for use in January 2006. The
below surface shaft costs consist of the excavation costs,  concrete associated
with the shaft liner and other  associated  sinking costs.  Pre-sinking for the
shaft was  completed  in January  2006 and sinking for the shaft  commenced  in
February 2006 and is expected to be completed in late 2007.

At December 31, 2005,  $21.4  million had been spent on the surface  assets for
Shaft No. 1. These amounts were  capitalized  as "capital works in progress" as
disclosed in Note 9 to the Financial Statements.  This accounting treatment was
based on Ivanhoe Mines assessment that these expenditures met the definition of
an asset under Statement of Financial  Accounting Concepts No. 6 ("CON 6"). CON
6 provides  the  following  definition,  "Assets are probable  future  economic
benefits  obtained or  controlled  by a  particular  entity as a result of past
transactions  and events."  (paragraph  25).  Management  determined that these
surface  assets  have the three  essential  characteristics  of an asset  (CON6
paragraph 26):

o   Embodies a probable  future  benefit that involves a capacity  singly or in
    combination  with other  assets,  to  contribute  directly or indirectly to
    future cash net inflows.  The surface assets will be used for either future
    underground  exploration at the existing or alternative  sites, the results
    of which we believe  will bring  probable  future net cash  inflows;  or to
    facilitate production activities.
o   A particular entity can obtain the benefit and control others access to it.
    Ivanhoe  Mines can obtain the  benefit and  control  others'  access to the
    assets; and
o   The  transaction  or other event  giving rise to the  entity's  right to or
    control of the benefit has already occurred. Ivanhoe Mines already owns and
    controls the assets.

Management  further determined that the surface assets are tangible assets that
can be sold or transferred to other locations to further either  exploration or
production  activities.  This is in contrast to the below  surface  shaft costs
which cannot be transferred to other  locations or dismantled and sold to third
parties.  The Company has also confirmed with independent  third parties that a
market does exist for used mining equipment and above ground infrastructure.

The Company also concluded that the sinking costs  amounting to $2.4 million at
December 31, 2005,  did not meet the definition of an asset since they were not
tangible or  exchangeable  (CON6 paragraph 26). These costs relate to the below
surface  costs that cannot be moved or reused at other sites.  These costs have
been expensed as  exploration  costs as incurred  during 2005.  From January 1,
2006 to October  31, 2006 a further  $27  million of below  surface  costs were
expensed. Future sinking costs will be treated in the same manner.

Ivanhoe Mines determined based on this analysis that an asset had been acquired
and it was appropriate to capitalize the  acquisition  costs. At the end of the
reporting  period the Company  considered  whether a day two  impairment of the
surface  assets had  occurred.  In  establishing  whether an  impairment of the



Page 4 of 6


assets had occurred under FASB  Statement No 144,  Accounting for Impairment or
Disposal of Long-Lived Assets,  reference was made to EITF 04-3: Mining Assets:
Impairment and Business Combinations.

A major issue addressed by the EITF was Issue 2:

        "Whether an entity should consider the future cash flows associated
        with value beyond proven and probable  reserves  (VBPP) in the cash
        flow  analysis  used to test  mining  assets for  impairment  under
        Statement 144".

The conclusion of the Task Force was:

        "On  Issue 2, the Task  Force  reached a  consensus  that an entity
        should include the cash flows  associated with VBPP in estimates of
        future  cash flows  (both  discounted  and  undiscounted)  used for
        determining whether a mining asset is impaired under Statement 144.
        The Task Force noted that  estimated cash flows also should include
        the  estimated  cash  outflows  required to develop and extract the
        VBPP."

Ivanhoe Mines considered the potential  impairment of these assets by comparing
the carrying  value of property,  plant and equipment and the mineral  property
assets to the cash flows that are  contained in the IDP and the disposal  value
that could be obtained from a timely  disposition  of the surface  assets.  The
conclusion of management  was that the assets were not impaired at December 31,
2005.  Ivanhoe Mines continues to consider  whether an indication of impairment
is present at each reporting period.

OTHER CONSIDERATIONS
- --------------------

The Division of Corporation Finance issued FREQUENTLY  REQUESTED ACCOUNTING AND
FINANCIAL REPORTING INTERPRETATIONS AND GUIDANCE in March 31, 2001 which stated
with respect to mining exploration costs that:

        "Recoverability  of capitalized costs is likely to be insupportable
        under FASB Statement No. 121 prior to determining  the existence of
        a commercially minable deposit, as contemplated by Industry Guide 7
        for a mining company in the  exploration  stage.  As a result,  the
        staff  would  generally  challenge  capitalization  of  exploration
        costs, and believes that those costs should be expensed as incurred
        during the exploration stage under US GAAP."

Ivanhoe  Mines  believes  that the  Company's  accounting  policy  follows this
guidance in that exploration  costs,  including  amortization of capital assets
used in  exploration  activities,  are expensed prior to the  establishment  of
proven and probable reserves. Management believes that the presumption that the
"recoverability  of  capitalized  costs is likely to be  insupportable"  can be
rebutted with respect to costs  capitalized  by the Company to property,  plant
and equipment.

CONCLUSION
- ----------

Based on the above, the Company  concludes that its accounting  policies are in
accordance  with US GAAP and SEC  Industry  Guide 7.  Specifically  the Company
considers that the  expenditures  in question  represent an asset in accordance
with CON 6 and that  recoverability  of costs is supportable in accordance with
the  provisions  of FASB 144 and EITF  04-3.  Therefore  it is  appropriate  to
capitalize  the surface  expenditures  as assets and depreciate the assets over
their useful lives.  Depreciation  charges during the exploration stage will be
expensed as exploration costs whereas thereafter the depreciation  charges will
be  capitalized  as  development  costs,  or  as  a  cost  of  production,   as
appropriate.  This  treatment  is  consistent  with  our  property,  plant  and
equipment accounting policy in Note 2 (h) of the Financial Statements.

As a follow-up  to the IDP, on January 30, 2006 the Company  announced  that an
independent  estimate  prepared by GRD Minproc  Limited,  of Perth,  Australia,
upgraded the Measured and Indicated gold and copper resources  contained within
the planned open-pit  deposits in the southern part of the Company's Oyu Tolgoi
Project to the Proven and Probable Mineral Reserve  categories.  The conversion
of previously classified resources to proven and probable reserves evidence the
merits of this property,  however this subsequent  event was not the basis upon
which the Company considered it appropriate to capitalize the surface assets.
