The audit was undertaken in accordance with Regulation 34 and Appendix 7 of the National Environmental Management Act (Act 107 of 1998) (NEMA) Environmental Impact Assessment (EIA) Regulations, 2014 (as amended). The Retained Operations Consolidated EMPr includes the following operations: Waterval smelter; Acid Converting Process (ACP) facilities; Rustenburg Base Metal Refinery (RBMR); and Precious Metal Refinery (PMR). It is SRK’s understanding that the Frank Concentrator has been formally decommissioned under an Environmental Authorisation and that rehabilitation of this facility will take place in the near future in accordance with the environmental commitments contained in the authorisation document and EMP for this facility (not included within the ambit of this audit). With regards to the Western Limb Distribution Center (WLDC), it is assumed that the conditions contained within the Consolidated EMPR (included in Appendix C1) are applicable to this facility as no EMPR amendment/addendum since 2002 was issued directly to this facility. Audit results During the audit, the RPM personnel demonstrated a good understanding of the environmental management issues on site and the requirements of the Consolidated EMPR. Compliance achieved by the RPM operations largely related to the following: The combined efforts of and experienced and knowledgeable environmental team comprising of an environmental manager, two environmental coordinators and two environmental officers (who are each responsible for their particular operations) to ensuring compliance to the various environmental permits held by the retained operations Ongoing monitoring relating to surface water, groundwater and air quality parameters Ongoing engagement with relevant stakeholders Having an effective system to record and action incidents as they arise (Enablon) to ensure these are addressed as per an action plan which is generated per incident The audit results indicated that the non-compliances related to the following: Conditions within the EMPr which are either not practical, not relevant or not achievable which would need to be amended through an EMPr amendment process. It is the Auditor’s understanding that the EMPr amendment is planned for 2020/2021 Extension of various monitoring systems to encompass the effects of the Retained Operations on off-site receptors Several ongoing challenges around overflow of dams and resulting potential pollution to soils and water resources. Most of the non-compliances noted included conditions which are no longer applicable or practical for the RPM operations to implement. It is SRK’s understanding that the Consolidated EMPr will be amended in the near future (2020/2021) to either amend or remove these conditions.

In summary, the audit results indicated the following: The retained operations are largely compliant with the conditions contained within the EMPr. A higher level of compliance is attainable subject to the amendment of the EMPr; and Ongoing efforts by the environmental team will ensure that partial non-compliances are rated as compliant in the next audit.
