Managing Water Risk

Water is a vital input for our business and our host communities. Therefore, our water stewardship is of critical importance to our business and our stakeholders. Our approach is to ensure both an adequate supply of water for our operations and to protect (or improve) the supply and quality of water for our local communities.

 

This approach is underpinned by a set of ambitious internal targets to ensure responsible water use. Our targets include:

 

  • Recycle 75% of process water, by 2020. Improve water use efficiency to 1.4m3/tonne of ore milled, with freshwater use in our processing plant to be below
  • 0.5 m3/tonnes milled.
  • Monitor and ensure all water discharged
  • by our operations is returned to source at the same or better quality, including zero uncontrolled discharges.

 

The water our mines abstract is drawn from a combination of surface water (rivers and dams), groundwater and water from mine dewatering. The amount of freshwater we

can abstract is strictly limited by government issued permits, and we carefully monitor abstraction rates to ensure compliance with the permits. We take equal care with any water we discharge back into the environment, testing all water to be discharged for traces of 30 different chemicals prior to discharge.

 

Complementing the group’s targets we have in place, each operational mine has its own tailored water management plan, which takes into account the different catchment users needs, the specific climate, surface and ground water availability and quality, evapotranspiration rates of the site as well as permit allowances and details how water is to be managed. Every mine is different. For example, the Loulo, Gounkoto, Morila and Tongon mines are located in a tropical savanna zone, which is prone to water stress, while Kibali is located in a tropical wet climate zone and enjoys a long rainy season.
