Water stewardship

Water is an essential resource for our operations, as it is used intensively in both our mining and processing operations. We have a responsibility to effectively manage any interaction and minimise any impacts on water.

We recognise the importance of working together with communities to ensure greater stewardship of this precious resource and that access to clean, safe water is a basic human right.

Water Stewardship Strategy

Kenmare's Water Stewardship Strategy, approved by the Board of Directors, guides us in ensuring the access rights of others are not impacted by our operations, that water-related risks are managed, opportunities for increased water re-use are implemented and all Kenmare employees value water as a precious resource.

Kenmare’s water stewardship strategy continues to focus on five key areas of activity:
1. Watershed management – to secure water supply for current and future operations while protecting and enhancing other water uses. This is implemented through a site-wide water balance, environmental monitoring and surface water and groundwater modelling to measure the current and projected operational water demand and to characterise the surface water and ground water systems
2. Impact mitigation – to proactively mitigate environmental and social impacts associated with the abstraction, use and discharge of water and to enhance water use opportunities
3. Operational performance – the site-wide water balance is used to manage water as an asset, through improved performance and compliance with all commitments
4. External engagement – to collaborate and engage externally on water policy, management, and challenges in Mozambique to create shared value
5. Internal collaboration – to support coordination across all water management areas of the business.

An essential resource

Kenmare extracts water from a local aquifer. This water is used to assist in the mining, processing of the sand, tailings deposition, dust suppression and water and sanitation supplies. With chemical-free mining and processing operations, most of the water used at Moma is returned to the groundwater table, with the exception of evaporation. The aquifer also receives annual rainfall recharge.

Current groundwater withdrawal volumes are well within regulatory-approved withdrawal volumes and due to the nature of mineral sands production there are no discharges of waste water to the environment.

Low water stress

The World Resources Institute (WRI) AqueductTM tool maps water risks such as floods, droughts, and stress, using open-source, peer reviewed data. This tool indicates that the Moma Mine extracts 100% of its water requirements from an area of low baseline water stress and projections as far out as 2040 indicate a similar low water stress.

Kenmare is working to align our water reporting to the ICMM Guidelines on Water Reporting, which incorporate the Minerals Council of Australia Water Accounting Framework (WAF).
