Implicit modelling is an amazing methodology. The capacity to rapidly build and update models combined with the possibility of testing multiple hypotheses reflects in a much more flexible and dynamic workflow that also saves time and money. A future where modellers and geologists just remember manual methods is not far away.

The vision of allowing geologists to focus on their data and interpretation, rather than on how to operate a software package is becoming a reality. It may actually yield the surprising result of less time in front of computers and more time in the field.

I feel the next stage is directly linking the model to the real world through augmented reality, and expanding the scope of real time data collection to adjust modelled boundaries and flag unexpected irregularities in Geology, not just topological position. This is critical for accurate and reactive planning to support real-time mining processes.

The need to drive costs down, improve efficiencies at the mine and better analyse risk in a mining project will necessitate and drive the future development of implicit modelling techniques. The dynamic nature of mining is best suited to the rapid evaluation of resources made possible by implicit modelling.

The future of implicit modelling is making it standard industry practice to generate multiple resource models that capture a range of interpretations and uncertainties. This will improve communication between geoscience and geostatistics and improve business decisions.

Implicit modelling is set to completely replace explicit methods within a few years. The real benefits of implicit modelling are still to be fully realised – rapid updating, incorporation into automated modelling workflows, practical assessment of uncertainty from various sources.

As implicit modelling becomes more and more accepted there will be significant improvements in workflow which will greatly improve validity. As the process becomes more understood and the software moves towards having greater control on domaining and sample selection we will likely see an introduction of implicit modelling derived grade models into the resource sphere.

In the wake of implicit modelling will be reconsiderations of common practices in the course of resource estimation. Significant improvements in the accuracy and prediction of models will surely follow as the result of more detailed and appropriate geologic models.

  • Jonathan Brown says:

    Even with very sophisticated satellites and other devices that dump huge amounts of data in to models we lack the ability to remove uncertainty from a surface event such as weather. Why do we think that we can achieve it underground?

  • James Harrington says:

    It’s not about removing uncertainty; it’s about characterizing uncertainty.
