Merafe Resources Integrated Annual Report 2018

MERAFE RESOURCES INTEGRATED ANNUAL REPORT 2018 26 PERFORMANCE Incidents and compliance It is always the Venture’s aim to have no environmental incidents at its operations. It monitors, reports, investigates and remediates any incidents that occur and applies lessons learnt to prevent similar incidents in the future. Its operations are required to report any environmental high potential risk incidents ("HPRIs"), including near-misses, that could have resulted in a category 4 or 5 incident, even when the actual impact was less significant. Environmental incidents recorded at the Venture’s operations also include incidents that occur as the result of contractor activity. The Venture has had no environmental fines, penalties or prosecutions at its operations for the past nine years. The Venture achieved its goal of no category 4 or 5 incidents recorded in its operations in 2018 and no category 4 or 5 incidents have been recorded in the Venture’s operations for the past nine years. Natural capital (continued) For further information on land use, see the Resources and Reserves Statement in our online Integrated Annual Report for 2018.

NO x is formed as a secondary emission through the air pollution control equipment due to the presence of nitrogen in the air. Small process changes in terms of gas volume and temperature can result in step changes in NO x emissions. Despite the variance from 2017 to 2018, emissions at the Venture do not exceed any ambient standards for NO x . Product stewardship The Venture monitors and addresses the impacts and risks associated with the use of its products throughout their life cycles, including during stages outside of its control, such as use, recovery, recycling and disposal. It works with national and international industry associations, its customers and suppliers to understand the environmental health and safety risks of its products and to find ways to mitigate these risks. In terms of Registration, Evaluation and Authorisation and Restriction of Chemicals ("REACH"), all the products that the Venture exports to countries in the European Union have been pre-registered, with the relevant pre- registration certificates and numbers available. The Venture is also actively involved in REACH. No products produced by the Venture, or their packaging materials, were reclaimed during 2018. To ensure the quality of its products, the Venture aligns its systems with the requirements of ISO 9001:2008 and some of its smelters are certified. Its laboratories are ISO 17025 accredited, which ensures that the methods and equipment it uses are accurate. Waste management and effluent and biodiversity management The mineral waste produced by the Venture in 2018 was 4.3 million tonnes.
