Letšeng mitigates the impact mining activities have on the environment through responsible environmental management that includes biodiversity preservation and rehabilitation of disturbed land.
To ensure responsible end of life of mine land use and rehabilitation, Letšeng conducts rehabilitation trials utilising waste rock.
Sustainable water management is a key priority for Letšeng and the operation has implemented a comprehensive water management strategy that includes quality preservation and usage reduction measures.
The cornerstone of Letšeng’s safety management strategy is “My Brother’s Keeper”. Being a Brother’s Keeper means taking responsibility for all team members and ensuring that they work safely.

The pits which are currently just over 250m deep, have a total footprint of 110ha and have a planned final depth of 450m placing them among the deepest pits in the world.
At more than 3 000 metres above sea level, winters at Letšeng Mine are always a challenge with extreme temperatures, wind and snow.
