Waste management


We work to minimise the impact of the waste our activities produce – and focus on the need to store waste safely.

Why this matters

By managing this waste responsibly, we can reduce impacts on the environment and people – and mitigate the risk of structural failure of our waste storage facilities.

Our approach

Most of the waste our activities generate is waste rock and residues from our production processes. We have systems in place to dispose of all our wastes responsibly.

Tailings, which is mineral waste from the processing of ores, are stored in specific storage facilities.  

Our tailings storage facilities are heavily regulated, and undergo regular inspections. 

Our assets monitor these facilities continuously to ensure their integrity and structural stability – and implement a catastrophic hazard protocol to minimise risk.

We reuse waste rock and other types of mineral waste as much as possible – such as in backfilling mines and building roads.
