Understanding Whittle Optimisation: The Foundation of Modern Mine Planning
For investors new to mining terminology, Whittle optimisation represents a sophisticated mathematical approach to determining the most economically viable pit design. Furthermore, this process considers multiple variables including ore grade distribution throughout the deposit, mining costs including equipment, labour, and materials, processing costs and metallurgical recovery rates, metal prices and revenue projections, and geotechnical parameters such as wall slope angles.
The optimisation generates what mining engineers call the "ultimate pit shell" – essentially the boundary that maximises net present value whilst ensuring operational safety and efficiency. For Marmota investors, this process will provide the first comprehensive economic framework for Aurora Tank, establishing whether the impressive drill results translate into a commercially viable mining operation.
The Whittle software creates three-dimensional models that evaluate millions of potential mining scenarios, considering factors such as ore body geometry, grade continuity, and operational constraints. In addition, this mathematical modelling approach enables mining companies to identify the optimal extraction sequence that balances immediate cash generation with long-term resource preservation.
