No offering of securities shall be made into the United States except pursuant to registration under the US Securities Act of 1933, as amended, or an exemption therefrom.

Neither this presentation nor any copy of it may be taken or transmitted or distributed or redistributed (directly or indirectly) in Canada or Japan. The distribution of this document in other jurisdictions may be restricted by law and persons into whose possession this document comes should inform themselves about, and observe, any such restrictions. This presentation is directed only at persons who (i) are persons falling within Article 49(2)(a) to (d) (“high net worth companies, unincorporated associations etc.”) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended) (the “Order”) or (ii) have professional experience in matters relating to investments falling within Article 19(5) of the Order or (iii) are outside the United Kingdom (all such persons being referred to as “relevant persons”). This presentation must not be acted on or relied on by persons who are not relevant persons. Information about Rio Tinto and Alcan Inc. (“Alcan”) included in this presentation is based on public information which has not been independently verified. Certain statistical and other information about BHP Billiton included in this presentation is sourced from publicly available third party sources. As such it presents the views of those third parties, but may not necessarily correspond to the views held by BHP Billiton.

Certain statements in this presentation are forward-looking statements. The forward-looking statements include statements regarding contribution synergies, future cost savings, the cost and timing of development projects, future production volumes, increases in production and infrastructure capacity, the identification of additional mineral Reserves and Resources and project lives and, without limitation, other statements typically containing words such as “intends”, “expects”, “anticipates”, “targets”, “plans”, “estimates” and words of similar import. These forward-looking statements speak only as at the date of this presentation. These statements are based on current expectations and beliefs and, by their nature, are subject to a number of known and unknown risks and uncertainties that could cause actual results, performance and achievements to differ materially from any expected future results, performance or achievements expressed or implied by such forward-looking statements. The forward-looking statements are based on numerous assumptions regarding BHP Billiton’s present and future business strategies and the environments in which BHP Billiton and Rio Tinto will operate in the future and such assumptions may or may not prove to be correct.

Disclaimer (Continued)

There are a number of factors that could cause actual results or performance to differ materially from those expressed or implied in the forward-looking statements. Factors that could cause actual results or performance to differ materially from those described in the forward-looking statements include, but are not limited to, BHP Billiton’s ability to successfully combine the businesses of BHP Billiton and Rio Tinto and to realise expected synergies from that combination, the presence of a competitive proposal in relation to Rio Tinto, satisfaction of any conditions to any proposed transaction, including the receipt of required regulatory and anti-trust approvals, Rio Tinto’s willingness to enter into any proposed transaction, the successful completion of any transaction, as well as additional factors such as changes in global, political, economic, business, competitive, market or regulatory forces, future exchange and interest rates, changes in tax rates, future business combinations or dispositions and the outcome of litigation and government actions. Additional risks and factors that could cause BHP Billiton results to differ materially from those described in the forward-looking statements can be found in BHP Billiton’s filings with the US Securities and Exchange Commission (“SEC”), including BHP Billiton’s Annual Report on Form 20-F for the fiscal year-ended June 30, 2007, and Rio Tinto’s and Alcan’s filings with the SEC, including Rio Tinto’s Annual Report on Form 20-F for the fiscal year-ended December 31, 2006 and Alcan’s Annual Report on Form 20-F for the fiscal year-ended December 31, 2006, which are available at the SEC’s website (http://www.sec.gov). Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. The information and opinions expressed in this presentation are subject to change without notice and BHP Billiton expressly disclaims any obligation (except as required by law or the rules of the UK Listing Authority and the London Stock Exchange, the UK Takeover Panel, or the listing rules of ASX Limited) or undertaking to disseminate any updates or revisions to any forward-looking statements contained herein to reflect any change in BHP Billiton’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based.

None of the statements concerning expected cost savings, revenue benefits (and resulting incremental EBITDA) and EPS accretion in this presentation should be interpreted to mean that the future earnings per share of the enlarged BHP Billiton group for current and future financial years will necessarily match or exceed the historical or published earnings per share of BHP Billiton, and the actual estimated cost savings and revenue benefits (and resulting EBITDA enhancement) may be materially greater or less than estimated.

The SEC generally permits mining companies in their filings with the SEC to disclose only those mineral deposits that the company can economically and legally extract. Certain measures in this presentation, including “Resources”, “potential mineralisation” and “targeted mineralisation”, would not generally be permitted in an SEC filing. The material denoted by such terms is not proven or probable Reserves as such terms are used in the SEC’s Industry Guide 7, and there can be no assurance that BHP Billiton will be able to convert such material to proven or probable Reserves or extract such material economically. BHP Billiton urges investors to refer to its Annual Report on Form 20-F for the fiscal year ended June 30, 2007, for its most recent statement of mineral Reserves calculated in accordance with Industry Guide 7.

Goldman Sachs International and its affiliates and Gresham Partners are acting for BHP Billiton and no-one else in connection with the proposals referred to in this presentation and will not be responsible to any other person for providing the protections afforded to their respective clients, or for providing advice in relation to such proposals or any other transaction, arrangement or matter referred to herein.

In connection with BHP Billiton’s proposed combination with Rio Tinto by way of the proposed Schemes of Arrangement (the “Schemes”), the new BHP Billiton shares to be issued to Rio Tinto shareholders under the terms of the Schemes have not been, and will not be, registered under the US Securities Act of 1933, as amended, or under the securities laws of any state, district or other jurisdiction of the United States, and no regulatory clearances in respect of the new BHP Billiton shares have been, or (possibly with certain limited exceptions) will be, applied for in any jurisdiction of the United States. It is expected that the new BHP Billiton shares will be issued in reliance upon the exemption from the registration requirements of the US

Securities Act provided by Section 3(a)(10) thereof.

In the event that the proposed Schemes do not qualify (or BHP Billiton otherwise elects pursuant to its right to proceed with the transaction in a manner that does not qualify) for an exemption from the registration requirements of the US Securities Act, BHP Billiton would expect to register the offer and sale of the securities it would issue to Rio Tinto US shareholders and Rio Tinto ADS holders by filing with the SEC a registration statement (the “Registration Statement”), which would contain a prospectus (“Prospectus”), as well as other relevant materials. No such materials have yet been filed. This communication is not a substitute for any Registration Statement or Prospectus that BHP Billiton may file with the SEC.

US INVESTORS AND US HOLDERS OF RIO TINTO SECURITIES AND ALL HOLDERS OF RIO TINTO ADSs ARE URGED TO READ THE REGISTRATION STATEMENT AND PROSPECTUS AND ANY OTHER DOCUMENTS MADE AVAILABLE TO THEM AND/OR FILED WITH THE SEC REGARDING THE POTENTIAL TRANSACTION, AS WELL AS ANY AMENDMENTS AND SUPPLEMENTS TO THOSE DOCUMENTS, IF AND WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION. If and when filed, investors and security holders will be able to obtain a free copy of the Registration Statement and Prospectus as well as other relevant documents filed with the SEC at the SEC’s website (http://www.sec.gov), once such documents are filed with the SEC. Copies of such documents may also be obtained from BHP Billiton without charge, once they are filed with the SEC.

Competent Persons for Mineral Resources and Ore Reserves are named in the BHP Billiton Annual Report 2007, which can be viewed at www.bhpbilliton.com. Heath Arvidson, who is a member of AusIMM and a full time employee of BHP Billiton and has the required qualifications and experience, is a Competent Person for the probabilistic assessment of Potential Mineralisation, which is reported under Section 18 of the JORC code. Heath Arvidson verifies that the relevant content of this document is based on and fairly reflects the information in the supporting documentation relating to Potential Mineralisation.

Notes:

• Bar size represents the high range of announced potential mineralisation.

• BHP Billiton Source: Reserves and resources – BHP Billiton 2007 Annual Report. Resources are quoted inclusive of Reserves. The Potential Mineralisation (Exploration Target) was announced by BHP Billiton in October 2007, and is based on probabilistic assessment of areas across the Pilbara using surface mapping, geophysics, known regional geology and some limited drill results acquired over the last 40 years of exploration. The target range is conceptual in nature, there has not been sufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource; BHP Billiton Mineral Resource information should be read together with and subject to the notes set out in the BHP Billiton Annual Report 2007. This document can be viewed at: www.bhpbilliton.com

• Rio Tinto: Reserves and Resources – Rio Tinto 2006 Annual Report (Rio Tinto Resources on the chart shown inclusive of Reserves); potential Mineralisation based on Rio Tinto Investor Presentation, 26 November 2007, “Delivering exceptional growth”.

• The measures “Resources”, “potential mineralisation” and “targeted mineralisation” are not defined in the SEC’s Industry Guide 7 and the material denoted by such terms is not proven or probable reserves as defined therein. There can be no assurance that we will be able to convert such material to proven or probable reserves or to extract it economically. We urge investors to refer to our Annual Report on Form 20-F for the fiscal year ended June 30, 2007 for our most recent statements of mineral reserves calculated in accordance with Industry Guide 7.
