GEOVIA Whittle ™



When exploration and mining companies need to evaluate the financial viability and the optimal mine strategy for a deposit, they turn to the industry leading strategic mine planning solution – GEOVIA Whittle™. Companies depend on Whittle to help them determine their investment strategy and to deliver robust mine plans that maximize profitability by taking into account real mining constraints.

GEOVIA Whittle delivers trusted results and is used in scoping, feasibility, life-of-mine scheduling, and in the ongoing re-evaluation of mine plans throughout the production phase. Because pit optimization alone is not enough to unlock the full economic potential of your operation, Whittle provides mine optimization, which enables significant increases in project value over and above pit optimization. With its 64-bit platform, Whittle handles large data sets designed to optimize and run big models. To aid with these ever increase larger datasets, in addition to Lerchs-Grossmann, Whittle also includes the Pseudoflow algorithm which is renowned for the speed in which it generates pit shells, even for these large datasets.

Accelerate from pit shells to practical pushbacks targeting NPV and mining width

GEOVIA Whittle ™

Create Strategic Mine Plans linking in Milawa’s Life of Mine Scheduling approach focused on NPV or material balance.

  • Determine best set of practical pushbacks or mining phases
  • Develop optimal and achievable life of mine schedules
  • Handle complex mining and processing constraints
  • Calculate NPV based on realistic schedules supporting up to 50 pushbacks

 *The Pushback Optimizer role also includes all of the benefits of the Pit Optimizer role.

Blend your way to a higher NPV

GEOVIA Whittle ™

Optimize blend considering the schedule and existing stockpiles to ensure these are optimized at the same time, driven by the overall objective of maximizing the Net Present Value (NPV) of the whole operation.

  • Blend optimization based on Whittle schedules or imported schedule
  • Bulk blend scenario analysis considering multiple products with different specifications, prices, blending costs and blending limits
  • Handle multiple coal specifications and constraints such as minimum BTU, max ash and sulphur
  • Perform extractive blend factoring in blending costs and constraints, such as process recovery, prices and selling costs while limits are applied to the extractive process
  • Handle multiple stockpiles, different cut-offs, time dependant recoveries, initial size and grade while utilizing Whittles scheduling engine to determine the optimal blend strategy

*The Blend Optimizer role also includes all of the benefits of the Pushback Optimizer role.

Get more from your operation with multi-mine optimizer

GEOVIA Whittle ™

Perform a single optimization over a complex collection of mines all while maintaining individual work constraints for each mine. Producing a more realistic overall schedule from the different areas all within the one optimization framework.

  • Run a single optimization over a whole mining complex
  • Apply individual work constraints for each mine within a complex
  • Define unique physical constraints for each mine, such as mining width
  • Modify mining rate per mine in different scenarios
  • View, report and analyze all or individual mines in one go

 *The Multi-mine Optimizer role also includes all of the benefits of the Pushback Optimizer role.

Unlock the hidden NPV

GEOVIA Whittle ™

Simultaneously optimize schedules, cut-offs, stockpiles and blend for the life of the operation. Find better outcomes compared to traditional methods resulting in higher Net Present Value (NPV) for the operation.

  • Increase NPV beyond multiple sequential optimization mechanisms
  • Simultaneously optimize the optimization mechanisms for cut-off, blending, stockpiling and sequencing to create the ultimate mine schedule
  • Make individual optimization mechanisms more accessible in a single step
  • Analyze and report using both standard Whittle outputs and advanced spreadsheet reporting
  • Handle 30 processing paths as well as capital or CAPEX optimization

*The Simultaneous Optimizer role also includes all of the benefits of the Pushback Optimizer role.


Whittle helped us extend our bench across the orebody and come up with new cash flows. We have increased our ore reserves by more than 1.2 million tonnes in six months, and we expect extra years of production from the Youga mine.
