Throughput increase: Managing risk and challenges towards the end of mine life


A large hard rock opencast operation was nearing its end of life, yet needed to maintain volumes while reducing costs despite very challenging pit constraints

Our Approach:

  • MineLens was used as a tool to give mine management an overall sense of areas to improve
  • Highlighted improvement areas and practical steps
  • Expert visit critical to ensure technical complexities of pit was taken into account


  • Generated new ideas and “out of the box” thinking about mine performance and practices
  • MineLens report quoted for reference at site in future
  • Mine is currently facing management change - MineLens report is used by new mine manager as a good overview and action plan
  • Recommendations implemented with significant positive impact
  • Potential identified: increase annual ROM ore production by 11% and reduce maintenance cost by 51.4 Mn A$ and operating cost by 30.6 Mn A$
increase annual Run-Of-Mine (ROM) ore production
Mn A$ reduced maintenance cost
Mn A$ reduced operating cost
“MineLens provided unambiguous and practicable mining recommendations”
