Throughput increase: Managing risk and challenges towards the end of mine life
Challenge:
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
Results:
- 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$
11%
