Case Studies

Examples of strategic mine-planning decisions where disciplined optimisation changes the answer.

Holistic Mine Optimisation

This Case Study explores how mining, soil regeneration, agriculture, closure, and community value can be optimised together, using Holistic Present Value rather than mining NPV alone.

This Case Study covers truck and shovel fleet sizing, equipment matching, and annual fleet reviews, showing how this analysis helps operations maintain the right fleet scale as site conditions, costs, and productivity drivers change over time.

Mine Extension or Closure

This Case Study covers mine extensions, closure scenarios, and capital trade-off evaluation, showing how NPV-based assessment helps determine the options that best maximise whole-of-business value as reserves, mine scope, and project economics change over time.

Process Plant Expansion

This Case Study covers how processing plant expansions can be of substantial value to long life mine sites. It covers the right overarching objectives, expansion options and evaluation methods.

Integrated Multi-Mine Coal Optimisation

This Case Study covers coordinated Hunter Valley coal planning, showing how wash plant settings, pit choices, rail, port, equipment, and product strategy need to be optimised across multiple mines rather than isolated site plans.

Integrated Strategic Planning at EKATI

This Case Study covers how EKATI connected strategic intent, diamond resource value, development options, COMET schedules, risk scenarios, and annual planning into one value-driven planning system.

Operational Complexity in Open Pit Planning

This Case Study covers operational complexity in long-term open pit planning, using measurable indicators for bank advance, extraction rate, vertical phase spacing, and truck-ramp congestion.

Cash Flow Grades

This Case Study covers cash-flow grade ranking, showing why rocks with different throughput characteristics should be ranked by period value rather than grade, equivalent grade, or static net value alone.

Combined Open Pit and Underground Optimisation

This Case Study covers a combined open pit and underground strategic plan, showing how underground stopes, pit pushback value, stockpiles, processing capacity, and mine closure timing can be optimised together.
