| Each material topic above appears under either the environment, social or governance theme to which it primarily relates. However, there is crossover among ESG themes,meaning some material topics can be relevant to 2 or even all 3 themes. Accordingly, we work with themes and topics holistically, not in silos. |     |                              |     |                                           |     |                                     |     |                        |     |                              |     |                                 |                                  |                                       |     | Supply chaintransparency                |

Strategic report | Our approach to ESG

Reporting our performance Our materiality assessment records the threshold at which an issue or topic becomes important enough for us to report on externally. The importance of a topic is based on the significance of its impacts on, and risks and opportunities for, stakeholders. Our ESG materiality assessment considers our impacts externally and, conversely, the effect of external factors on our business. As an ICMM member, we commit to reporting on our ESG performance against the Global Reporting Initiative (GRI) standards and implementing the ICMM Performance Expectations (PEs). The ICMM Mining Principles framework focuses on the implementation of systems and practices related to a broad range of ESG areas. In 2022, we disclosed that we prioritised 26 of our 29 operating assets for validation within the 3-year cycle (2023-2025). There are now 30 operating assets and we have prioritised one additional asset for validation in 2025, thereby resulting in a total of 28 out of our 30 operating assets being prioritised for validation. Since 2022, we have been progressing the validations according to plan. In 2024, on-site third-party validations were completed for 12 of our priority operating and refining assets. The validation reports demonstrate a high level of alignment between the self-assessment and validation outcomes, with identification of relevant areas for improvement. Information for the 2023 and 2024 validation results is presented in the ICMM PE Summary tab in the 2024 Sustainability Fact Book . In 2024, we have also introduced a new tab
