Trading statement in respect of the 12 months ended 30 June 2010

In terms of paragraph 3.4(b) of the Listings Requirements of the JSE Limited a listed company is required to publish a trading statement as soon as it is satisfied that a reasonable degree of certainty exists that the financial results for the period to be reported on next will differ by at least 20% from those of the previous corresponding period.

Notwithstanding achieving increased sales volumes across most commodities and good cost control results, ARM’s provisional headline earnings for the 12 months to 30 June 2010 (in comparison to the corresponding 12 months to 30 June 2009) have been negatively impacted by:

• lower average US Dollar commodity prices received especially for iron ore and manganese; and
• a 16% strengthening of the Rand against the US Dollar.

The provisional basic earnings for ARM are, in addition, lower than that of the previous year owing to the non-recurrence of the R557 million exceptional gain on the restructuring of TEAL Exploration & Mining Incorporated (�TEAL�) in the previous financial year.

Accordingly, ARM announces that it expects headline earnings per share for the 12 months ended 30 June 2010 to decrease to between 785 and 825 cents per share (F2009: 1 094 cents per share). Basic earnings per share for the 12 months ended 30 June 2010 are expected to decrease to between 830 and 875 cents per share (F2009: 1 355 cents per share).

The financial information on which this trading statement is based has not been reviewed or reported on by the external auditors of ARM.

The company’s full year results will be released on Monday 30 August 2010.
