Ivanhoe Mines Ltd.: Alert Issued About False and Misleading Statements Published by the Australian and Business Spectator

MELBOURNE, AUSTRALIA -- (Marketwire) -- 09/15/10 -- Ivanhoe Mines Ltd. (TSX: IVN)(NYSE: IVN)(NASDAQ: IVN) -

Editors and journalists are advised that stories published in The Australian newspaper on September 15, 2010, and on the Business Spectator website on September 14, 2010, contained false and misleading information concerning Ivanhoe Mines and the rapidly advancing Oyu Tolgoi mine development project.

Flouting fundamental, fair journalistic practice, none of the instances of conjecture and blinkered speculation presented as facts were checked with Ivanhoe Mines in advance of publication.

For example:

--  The curiously similar claims by both publications that Ivanhoe Mines
    alone has delayed the selection of an arbitrator to evaluate a complaint
    by Rio Tinto are false. Ivanhoe has negotiated in good faith throughout
    the process in an effort to reach agreement on an arbitrator who is
    entirely independent of the parties and the issues to be considered in
    the arbitration. The truth is that Ivanhoe Mines and Rio Tinto
    previously reached agreement on an arbitrator, but were unable to
    proceed because of a conflict later identified by the proposed
    arbitrator involving a company associated with Rio Tinto. Rio Tinto and
    Ivanhoe Mines subsequently have reached a tentative agreement on a new,
    independent arbitrator, subject to his clearance of conflicts, and
    Ivanhoe expects that the selection process will be concluded shortly.

--  The claim that Ivanhoe Mines has stated that the cost to build and
    initiate operations at the first phase of the Oyu Tolgoi copper-gold
    project will be US$4 billion is false. As Ivanhoe Mines announced on May
    11, 2010, prominent, independent consultants estimated that the required
    investment during the next three years would be approximately US$4.6
    billion - which includes a $1 billion investment on a portion of the
    phase-two development of the planned underground mine.

--  The allegation by The Australian that Ivanhoe Mines is substantially
    underestimating the capital cost is glib editorializing, masqueraded as
    news, unsupported by any offered evidence and has no foundation in fact.
    The project is ahead of schedule and major contracts are within budget.

--  The claim by the Business Spectator, that Ivanhoe Mines 'purported to
    introduce' a shareholders' rights plan earlier this year, is just plain
    bizarre. It is a matter of unquestionable public record that the
    introduction of a rights plan was endorsed by 95% of the votes cast by
    minority shareholders at Ivanhoe's annual general meeting on May 7,
    2010, in part to prevent a creeping takeover of the company.

--  Rio Tinto is not limited to a 44% stake in Ivanhoe Mines under its
    current agreement; presently, it is eligible to acquire up to 46.65% of
    Ivanhoe's common shares.
