Water is a critical resource, integral to nearly every aspect of copper production, from dewatering and mineral processing to tailings management and dust suppression.

Our approach to water stewardship reflects our commitment to responsible water management throughout the mining lifecycle. We take a catchment based approach to manage surface and groundwater through a stakeholder inclusive process. We encourage water use efficiency across our business considering local climatic conditions, water availability and potential climate change impacts.

Our Environment, Water and Biodiversity Group Standard sets minimum requirements for the responsible use and protection of water resources and includes requirements for the management of water inputs (sourced from groundwater and surface water) and outputs (including stormwater, discharge and aquifer recharge).

Assets are also required to meet regulatory obligations and permit conditions for water abstraction, dewatering and discharge. Where water-related risks extend beyond regulatory coverage, we require our Assets to apply additional risk mitigation controls.

Information about our water stewardship is available in our FY26 Sustainability Report on page 95.
