Rio Tinto Share Savings Plan ("SSP")

The SSP is a savings-related share option plan which is open to employees around the world. Under the plan, participants in the US can save up to the US dollar equivalent of £250 per month for two years. At the end of the savings period participants may exercise an option over shares granted at a discount of up to 15 per cent to the market value at the time of grant.

Participants in the US plan must exercise their options within twenty-seven months from date of grant. In order to comply with the plan rules and US tax legislation the exercise date must fall between the maturity date (1 January 2013) and the end of the twenty-seven month period (4 January 2013). On this basis the exercise date for these options was fixed as 3 January 2013. The number of options to which participants are entitled is determined by the exercise price, the savings amount and the length of the savings contract.

Rio Tinto plc announces that, on 3 January 2013, Debra Valentine, a person discharging managerial responsibility (PDMR) of the Company, exercised options over ordinary shares, as detailed in the table below:
