Forward-Looking Statements



This announcement includes 'forward-looking statements' within the meaning of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. All statements other than
statements of historical facts included in this announcement, including, without
limitation, those regarding Rio Tinto's financial position, business strategy,
plans and objectives of management for future operations (including development
plans and objectives relating to Rio Tinto's products, production forecasts and
reserve and resource positions), are forward-looking statements. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors which may cause the actual results, performance or achievements of
Rio Tinto, or industry results, to be materially different from any future
results, performance or achievements expressed or implied by such
forward-looking statements.



Such forward-looking statements are based on numerous assumptions regarding Rio
Tinto's present and future business strategies and the environment in which Rio
Tinto will operate in the future. Among the important factors that could cause
Rio Tinto's actual results, performance or achievements to differ materially
from those in the forward-looking statements include, among others, levels of
demand and market prices, the ability to produce and transport products
profitably, the impact of foreign currency exchange rates on market prices and
operating costs, operational problems, political uncertainty and economic
conditions in relevant areas of the world, the actions of competitors,
activities by governmental authorities such as changes in taxation or regulation
and such other risk factors identified in Rio Tinto's most recent Annual Report
on Form 20-F filed with the United States Securities and Exchange Commission
(the 'SEC') or Form 6-Ks furnished to the SEC. Forward-looking statements
should, therefore, be construed in light of such risk factors and undue reliance
should not be placed on forward-looking statements. These forward-looking
statements speak only as of the date of this announcement. Rio Tinto expressly
disclaims any obligation or undertaking (except as required by applicable law,
the City Code on Takeovers and Mergers (the 'Takeover Code'), the UK Listing
Rules, the Disclosure and Transparency Rules of the Financial Services Authority
and the Listing Rules of the Australian Securities Exchange) to release publicly
any updates or revisions to any forward-looking statement contained herein to
reflect any change in Rio Tinto's expectations with regard thereto or any change
in events, conditions or circumstances on which any such statement is based.



Nothing in this announcement should be interpreted to mean that future earnings
per share of Rio Tinto plc or Rio Tinto Limited will necessarily match or exceed
its historical published earnings per share.



Subject to the requirements of the Takeover Code, none of Rio Tinto, any of its
officers or any person named in this announcement with their consent or any
person involved in the preparation of this announcement makes any representation
or warranty (either express or implied) or gives any assurance that the implied
values, anticipated results, performance or achievements expressed or implied in
forward-looking statements contained in this announcement will be achieved.
