Directors’ responsibilities
The directors are responsible for the selection, preparation and presentation of the sustainability information, the identification of stakeholders and stakeholder requirements, material issues, for commitments with respect to sustainability performance, and establishing and maintaining appropriate performance management and internal control systems from which the reported information is derived, and for such internal control as the directors determine is necessary to enable the preparation of the report that is free from material misstatement, whether due to fraud or error.

• The GRI G3 Guidelines applied to the selected performance information
• The GRI G3 Guidelines for the B+ application level.

Our responsibility
Our responsibility is to express a limited assurance conclusion on the selected sustainability information based on our work performed. We conducted our engagement in accordance with International Standard on Assurance Engagements (ISAE) 3000, Assurance Engagements other than the Audits or Reviews of Historical Financial Information, issued by the International Auditing and Assurance Standards Board. That standard requires that we plan and perform our engagement to obtain limited assurance about whether the selected sustainability information is free from material misstatement.

Our procedures and the extent of our procedures depend on our judgement including the risks of material misstatement of the selected sustainability information. In making our risk assessments, we considered internal control relevant to Implats’ preparation of the report. In a limited assurance engagement, the evidence gathering procedures are less than where reasonable assurance is expressed. We believe the evidence we have obtained is sufficient and appropriate to provide a basis for our limited assurance conclusions.

• Interviewing management and senior executives at Group level to assess the application of the GRI G3 principles and to obtain an understanding of the general control environment relative to the reported sustainability information
• Obtaining an understanding of the processes and systems which generate, aggregate and monitor the selected sustainability information;
• Inspecting supporting documentation and performing analytical procedures;
• Visiting a risk based selection of four operation sites, including Rustenburg (mining, concentrating and smelting), Springs (refineries), Marula (mining and concentrating) and Zimplats (mining and concentrating).
• Conducting an application level check on the report to ensure all disclosure requirements of the GRI B+ application level have been adhered to.
• Evaluating whether the information presented in the report is consistent with our findings, overall knowledge and experience of sustainability management and performance at Implats.

1. On the selected performance information

Based on our work performed, nothing has come to our attention that causes us to believe that the selected sustainability information set out in 1 above for the year ended 30 June 2011 is not fairly stated, in all material respects, in accordance with the GRI G3 Guidelines.

2. On Implats’ self-declaration of a GRI B+ application level

Based on our work performed, nothing has come to our attention that causes us to believe that Implats’ self-declaration of a B+ application level is not fairly stated, in all material respects, on the basis of the GRI G3 Guidelines.

Limitation of liability
Our work has been undertaken to enable us to express a limited assurance conclusion on the selected sustainability information to the directors of Implats in accordance with the terms of our engagement, and for no other purpose. We do not accept or assume liability to any party other than Implats, for our work, for this report, or for the conclusion we have reached.
