SRK’s Peter Gleeson talks about Leapfrog EDGE, our new resource estimation solution that’s quick to master and saves time without compromising on quality.
Peter Gleeson, an expert with thirty years’ experience in resource estimation and mining geology tells us what he likes about Leapfrog EDGE, where he sees the future of resource estimation heading and why tools like EDGE will become so essential.
How has resource estimation or geostatistics changed over the last 10 years?
It’s become a lot more sophisticated. The market has moved from just using general mining packages to using niche packages that specialise in a specific area. Leapfrog EDGE combines many of the tools from these specialist packages into an all round estimation package. They have learnt from the mistakes of others and listened to what the resource geologists need. Examples of this include automatic Swath validation plots, automatic Boundary Analysis plots and improved ways of interpreting variography.
How do you think it will change over the next 10 years?
The industry needs more dynamic estimation models. A single static model for the life of mine is no longer good enough. Management want to test risk in a project or estimate. Only having one model that takes months to update is a barrier to this process. Leapfrog EDGE offers the opportunity to perform multiple realisations of an estimate in a relatively short time frame compared to other software.
What is one part of the resource estimation process that is often overlooked?
The geology. People put a lot of effort into geostatistics and they make fundamental mistakes as they don’t understand the geology. Combining the power of Leapfrog Geo with a fully integrated estimation workflow means the practitioner can give stronger emphasis to providing a robust geological model to underpin the estimate. Geostatistics will not save you if your geological domains are incorrect. Hence the acronym EDGE (Estimation, Domaining and Geostatistical Evaluation), with the emphasis on domaining. Working directly with Leapfrog Geo means resource domain models can often be updated in minutes as new data becomes available rather than days or weeks. Despite the improvements in efficiency of these new tools the fundamental input and understanding should be through good geology.
