Building the foundation for next-generation mining

In early 2020, South32 completed a US $30 million voluntary cleanup of mine waste left by a previous miner at the Hermosa project in the last century. This helped to:

  • Save taxpayers money.
  • Restore the natural environment.
  • Stop heavy metals from polluting local waterways.
