Notice

Rio Tinto has prepared this notice to clarify certain disclosures made by it in the context of the Annual Report on Form 20-F on page 11 filed with the Commission on March 2, 2017 relating to the payment of dividends to the Iranian Foreign Investments Company (IFIC) arising out of Rio Tinto’s Rössing Uranium Limited (Rössing) operations: 

To confirm, IFIC was not paid any portion of the dividends declared by Rössing in March and August 2016. Approximately US$13.6 million (representing IFIC’s portion of the dividends declared in 2016) was deposited into a restricted bank account in Namibia held in favour of IFIC since 2008. All dividends held in the restricted bank account in Namibia remain inaccessible to IFIC at this time.
