In your opinion how has resource estimation or geostatistics changed over the last 10 years?
Resource estimation has changed over the past 10 years in a few areas. First, regulators and consumers of technical reports have driven improvements by demanding greater responsibility and accountability for the predictions. Also, industry and public both have a better understanding of resource confidence. For the practitioner, recent developments in software applications have provided toolkits that enable the assimilation of multiple data types and much more rapid analysis and modelling than previously. Improvements in computer hardware have also made it possible to tackle larger datasets and models.

Resource estimation will continue to change, with punctuated evolution from new applications like Leapfrog EDGE.

Geoestima’s Principal Consultant, Orlando Rojas, discusses his testing of Leapfrog EDGE

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.

Mastering new tools for today’s resource estimation challenges

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.

Leapfrog’s role in revealing and enhancing the value of the Bozshakol deposit

The Bozshakol mine, operated by KAZ Minerals in northern Kazakhstan was the largest greenfield development project in Kazakhstan when under construction and is among the largest newly developed copper deposits in the world. It will process around 30 million tonnes of copper per year.

In pursuit of their large scale, low cost goal KAZ Minerals are implementing the most modern technology to ensure the level of automation and efficiency is high.

Leapfrog is allowing us to produce geological models in a fraction of the time (about a week at most). Without Leapfrog I’d estimate to produce just the geological model would take about four months.” Ashley Brown, Head Resource Definition, KAZ Minerals

Leapfrog and the Integra Gold Rush Challenge

The 2015 Integra Gold Rush Challenge was a crowd-sourcing competition inviting participants to help uncover the next big gold discovery in Canada’s Val-d’Ors, Quebec. Crowdsourcing offers mining an alternative to traditional approaches as it harnesses the accumulated wisdom of a wide and diverse group of individuals.

Leapfrog was the official 3D modelling partner. With access to over six terabytes of digital mining and exploration data, it was a great opportunity to showcase our powerful FastRBF™ engine. Over 1,300 participants registered to use the free Leapfrog Gold Rush licences we provided, including all of the five finalists.
