FORWARD-LOOKING STATEMENTS
This prospectus supplement contains and incorporates by reference certain forward-looking statements with respect to the financial condition, results of
operations and business of the Rio Tinto Group. These statements are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 (the
"Securities Act") and Section 21E of the Exchange Act. The words "intend," "aim," "project," "anticipate," "estimate," "plan," "believe," "expect," "may," "should,"
"will" or similar expressions, commonly identify such forward-looking statements.
Examples of forward-looking statements contained in or incorporated by reference in this prospectus supplement include those regarding estimated ore reserves,
anticipated production or construction dates, costs, outputs and productive lives of assets or similar factors. Forward-looking statements involve known and unknown
risks, uncertainties, assumptions and other factors set forth in this document that are beyond the Group's control. For example, future ore reserves will be based in part
on market prices that may vary significantly from current levels. These may materially affect the timing and feasibility of particular developments. Other factors include
the ability to produce and transport products profitably, demand for our products, the effect of foreign currency exchange rates on market prices and operating costs, and
activities by governmental authorities, such as changes in taxation or regulation, and political uncertainty.
In light of these risks, uncertainties and assumptions, actual results could be materially different from projected future results expressed or implied by these
forward-looking statements which speak only as at the date of this prospectus supplement. Except as required by applicable regulations or by law, the Group does not
undertake any obligation to publicly update or revise any forward-looking statements, whether as a result of new information or future events. The Group cannot
guarantee that its forward-looking statements will not differ materially from actual results.
