The name, business address, present principal occupation or employment and citizenship of each of the executive officers and directors of each of the Rio Tinto Companies are set forth in Schedule A hereto and are incorporated by reference herein.

During the last five years, none of the Rio Tinto Companies nor, to the best of their knowledge, any of the persons listed in Schedule A hereto has been: (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of the Schedule 13D is hereby amended and supplemented as follows:

On June 28, 2013, the Rio Tinto Companies acquired the right to convert the total amount of the bridge funding agreement entered into between Rio Tinto’s affiliate, Rio Tinto South East Asia Limited (the “Rio Tinto Funding Company”), and the Company (the “OT Bridge Funding Agreement”) into Shares. By way of an example, had a conversion notice been served on the Company as at June 28, 2013 and subject to the assumptions below, Rio Tinto would have been entitled to acquire 47,545,691 Shares, representing 4.5 per cent of the outstanding Shares, at a conversion price per Share equal to 85 per cent of the volume weighted average trading price of the Shares on the NYSE for the five consecutive trading days prior to the date on which notice of the conversion was given to the Company.

The funds for the OT Bridge Funding Agreement were obtained from the working capital of Rio Tinto.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

The information in Item 6 is hereby incorporated by reference in this Item 4.

Except as otherwise set forth in Item 4 of the Schedule 13D, as amended hereby, none of the Rio Tinto Companies has any present plan or proposal that would relate to, or result in, any of the matters set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D. Notwithstanding the foregoing, the Rio Tinto Companies reserve their rights in full to change their intentions with respect to any and all matters referred to in Item 4 of Schedule 13D as they deem appropriate.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and supplemented as follows:

The responses of the Rio Tinto Companies to Rows (11) through (13) of the cover pages of this Schedule 13D and the information set forth in Item 3 are hereby incorporated by reference in this Item 5.

Each of the Rio Tinto Companies is deemed to beneficially own 558,528,911 Shares which represents 55.5 per cent of the Company’s outstanding Shares on a fully diluted basis.

Under the OT Bridge Funding Agreement, if the maximum principal amount of the agreement (US$225 million) were drawn down by the Company, and Rio Tinto were to have given notice of conversion of the total amount on June 28, 2013, Rio Tinto would have been entitled to acquire 47,545,691 Shares upon such conversion, representing 4.5 per cent of the then outstanding Shares. Prior to any conversion under the OT Bridge Funding Agreement, the Rio Tinto Companies are deemed to beneficially own 510,983,220 Shares, representing approximately 50.8 per cent of the outstanding Shares.

If Rio Tinto were fully to exercise the Series D Warrants (described in the amended Schedule 13D filed on April 20, 2012), Rio Tinto would acquire an additional 74,247,460 Shares. Following such issuance, Rio Tinto would beneficially own 632,776,371 Shares representing 56.1 per cent of the outstanding Shares.

Rio Tinto also has anti-dilution rights that permit it to acquire additional securities of the Company so as to maintain its proportional equity interest in the Company.

7

The percentage of Shares is based on 1,005,990,498 outstanding Shares as of June 27, 2013.

In addition, the Shares deemed beneficially owned by each of the Rio Tinto Companies with respect to which such person (i) has sole voting power, (ii) shares voting power, (iii) has sole dispositive power and (iv) shares dispositive power are listed in the responses to Items 7, 8, 9 and 10, respectively, of the cover page of this Schedule 13D relating to such person.

Except as disclosed in this Schedule 13D, none of the Rio Tinto Companies nor, to the best of their knowledge, any of the persons listed in Schedule A hereto, presently has the power to vote or to direct the vote or to dispose or direct the disposition of any other Shares which they may be deemed to beneficially own.

Under the OT Bridge Funding Agreement, the Rio Tinto Funding Company agreed to make available to the Company a convertible non-revolving term credit facility in an aggregate principal amount of up to US$225 million. Prior to an event of default thereunder, the outstanding principal amount will accrue interest at the one month LIBOR rate in effect immediately prior to the initial drawdown plus five per cent per year. The aggregate of all amounts outstanding, including principal, interest and fees (the “Loan Amount”), will be repayable on August 12, 2013 (the “Maturity Date”). The Bridge Financing Agreement will be used solely to fund expenditures in respect of the OT Project and interest and fees arising in respect of other financing arrangements by the Company relating to the OT Project.

At any time after the Maturity Date or upon the occurrence of an event of default (as defined in Section 17 of the OT Bridge Funding Agreement), Rio Tinto, through the Rio Tinto Funding Company, will have the right to convert all or part of the Loan Amount into Shares at a conversion price per Share equal to 85 per cent of the volume weighted average trading price of the Shares on the NYSE for the five consecutive trading days prior to the date on which the Rio Tinto Funding Company gave notice to the Company of the conversion. The aggregate number of Shares issuable on the exercise of the conversion right may not exceed 100,587,901, representing approximately 10 per cent of the outstanding Shares.
