We employ an integrated numerical modelling approach that combines operational experience with current best practices and innovative analytical techniques. Through numerical modelling, we provide engineering support for study-level projects, design assessments, and operational decisions. Our experts also use gravitational flow models to evaluate and optimise drawpoint extraction and reduce dilution.

By integrating the engineers responsible for numerical analysis early in our projects, we provide objective-driven modelling assessments that support robust engineering recommendations. This helps ensure that the methodology, inputs (such as material properties and stress), and expectations for modelling results are fully understood by all staff involved in a project.

Our use of advanced numerical models is based on extensive operational and consulting experience and understanding of analogue situations. We have carried out numerical analyses for projects at all stages from initial mine development through operations to mine closure.
