Geoestima’s Orlando Rojas, a senior resource consultant with over 25 years’ experience, shares his experience using Leapfrog EDGE on a strata-bound copper deposit during the rigorous pre-release programme.
Leapfrog EDGE is designed for today’s resource estimation challenges. How has resource estimation or geostatistics changed in the last 10 years?
I think the biggest change is that deposits have lower grades, which requires more accuracy from resource models and more parameters to predict the throughput and cash flows. We therefore need faster, and more versatile software, with traceable workflows.
Can you tell us about your experience using Leapfrog EDGE?
We have already completed a geological and resource model using only Leapfrog EDGE. It was a strata-bound copper deposit, we modelled the lithology and a mineralisation envelope. We performed estimations by ordinary kriging and inverse distance using two or three passes and then we compiled the results using the calculation tool. We approached the resource category using the data density function tool, which allows you to map data density within a search.
We conducted geological modelling, grade estimation and classification entirely in Leapfrog EDGE. The resulting mineral resources model built in Leapfrog EDGE conforms to all the industry-standard technical procedures. This confirms that this tool is a viable alternative for us.
The biggest benefit is that it delivers an intuitive workflow from geological modelling to resource estimation, with the added benefits of Leapfrog’s great visualisation and dynamic
updating capabilities. Leapfrog EDGE also allows you to save time exporting and importing files from different software.
