Introduction to Whittle for Polymetallic Pit Optimisation
Explore polymetallic pit optimisation by evaluating multiple metal values, operating costs, pit shells, pushback sequences, and mine schedule outputs.
This course introduces learners to the use of Whittle for preliminary open-pit optimisation of polymetallic deposits. Using a sample project containing multiple valuable elements, learners will explore how changes in mining costs, processing costs, metallurgical recovery, selling prices, and revenue factors influence the generation of nested pit shells. The course progresses from running an existing Whittle project and examining its outputs to modifying slope parameters, reviewing operational scenarios, and evaluating alternative pushback sequences. Learners will also examine schedule graphs and bench-level outputs to understand how mining tonnages, cash flows, NPV, internal rate of return (IRR), and life-of-mine indicators support strategic mine planning decisions.
