Water is a vital, shared resource that is integral to the lives and livelihoods of those communities surrounding QIT Madagascar Minerals (QMM) operations, and to the region’s long-term environmental stability. Access to clean drinking water is also a fundamental human right.
We take our responsibility to manage water very seriously.
Our water strategy provides an integrated approach to managing QMM’s current and future water-related challenges and objectives, across 3 pillars:
In April 2026, we published QMM’s 2025 Water Report, which covers monitoring between November 2024 and October 2025. Findings remain consistent with prior years: upstream and downstream river quality remains comparable, with most regulated metals falling below laboratory detection limits. The 2025 update also describes the peak flow channel (which obtained regulatory approval in September 2025) and the transition to the authorised release point to WMC605.
Water management requires continual evaluation and analysis to ensure that we avoid and mitigate potential impacts of our operations and implement leading practice. Together with our stakeholders, QMM is committed to continue developing solutions that work long-term.
We conduct an extensive monitoring program on water quality within the mine lease area and around Mandena, in compliance with regulatory requirements. We also conduct additional monitoring and sampling of groundwater, surface water, and marine water quality for the Port of Ehoala’s activities as part of this program.
In addition to QMM’s approved release point (previously WMC603; as of September 2025, WMC605), 2 sampling stations in the Mandromondromotra River have been selected to represent river quality data upstream and downstream of the approved release point. The map below shows the sampling station locations:
The communities where we operate are central to our water management strategy and sustainable mining vision. We are implementing a community-centred water engagement approach focused on:
