We regularly update this standard and undergo internal and externalassurance checks. Our operational TSFs have, or are developing, tailings responseplans and follow strict business resilience and communications protocols.                                                                                                                                                                                                                                                                                                                                                            |

The framework requires us to considerwhether sufficient water is available to supply both our operational demands and thedemands of other stakeholders within the broader catchment. We apply rigorous standardsand processes to ensure effective controls are in place at all sites. This includes our Groupwater quality protection and water management standard, and a standardised Group watermanagement control library which describes all controls identified to manage our waterrisks. Asset-specific climate change risk and resilience assessments further enablecontinued improvement of water risk management over time. |
| Damage to critical coastalinfrastructure(shipping berths, shiploaders, stackers/reclaimers,conveyors) resulting in operationaland supply chain disruptionlll                                               | Tropicalcyclone/storm,wind,storm surge                                        | Our coastal infrastructure is designed to withstand the wind loading and other impactsassociated with extreme events, including severe tropical cyclones. Establishedbusiness resilience management plans offer frameworks for response, continuity, andrecovery in the event of a natural catastrophe scenario, aiming to minimise damageand resume operations swiftly. Our engineering risk assessment program, includingasset-level critical risk assessments, considers natural catastrophe modelling andassociated risks, if appropriate.                                                                                                                                                                                                                         |
