Geological inputs to LOM planning – Understanding and managing these intrinsic uncertainties

Geological inputs to LOM planning – Understanding and managing these intrinsic uncertainties

Geologists provide essential technical information during all stages of exploration, feasibility, development, mine operations, closure and rehabilitation. Much of this information is used by mining engineers, metallurgists, environmental staff, operations staff and mine management for LOM planning.

But, almost everything geologists deliver to these staff are estimates and interpretations rather than FACTS, so how do geologists convey the fundamental uncertainties associated with their estimates and interpretations to non-geologists?

This workshop is aimed at all mining professionals and managers and will review the sources of geological uncertainty that feed into mineral resource and ore reserve estimates, and resultant LOM planning decisions as projects progress from scoping studies, prefeasibility, final feasibility and operations.

Workshop modules include:

  • Geological inputs to LOM planning
  • Contributions to geological uncertainty
  • Risk assessment and management systems
  • Approaches for identifying, documenting, understanding and communicating geological uncertainty


Case studies emphasising the importance of assessing geological uncertainty linked to LOM planning (including mining, processing, waste disposal and transport) are used to emphasise the importance of effectively managing geological risk. Group interaction and exercises are also used to illustrate and reinforce workshop concepts.

Presenter bio – Mark Berry is a geologist with over 38 years of experience working for small, medium and large organisations in the minerals industry. His experience spans exploration, feasibility and development, mine operations, management, research and development, consulting and professional development. He has authored/co-authored a range of technical papers and workshops, including his paper titled “Geological uncertainty – a key challenge for effective life-of-mine planning”, to be published in the 2018 AusIMM LOM Handbook.
