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, addressing the needs of other water users and for the environment to be protected. Our Environment, Water and Biodiversity Group Standard sets minimum requirements for the responsible use and protection of water resources across all activities and includes requirements for the management of water inputs (bore water, reservoir supply and mine dewatering) 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, additional monitoring and controls are required to be implemented. We encourage water use efficiency across our business considering local climatic conditions, water availability and potential climate change impacts.

How we use water across our Assets

Our Assets depend on both surface and groundwater sources for the mining and processing of our copper concentrate. Across each Asset, we promote responsible water use through efficiency, reuse and recycling and aim to return unconsumed water back to the catchment at the same or better quality than when it was extracted.
