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.

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 EDGE pre-release feedback

‘What a modeller geologist always wanted’

Leapfrog EDGE is a resource estimation solution that supports and advances industry practices to meet today’s challenges. Designed in collaboration with the industry, Leapfrog EDGE has undergone years of development and refinement in readiness for its market launch in November 2017.

Nearly 200 geologists with a variety of different backgrounds, experience and job roles used Leapfrog EDGE as part of a pre-release programme. This blog outlines the results of a recent survey on their experiences.

This feedback is based on Leapfrog EDGE 1.0. We expect the increased functionality in the recently released Leapfrog EDGE 2.0 to add even more value and solve additional issues experienced in resource estimation.

Seamless integration with geology

A key feature of the software, introduced to address a need identified in the early research, is the seamless integration of the resource estimation process with the geological model. Leapfrog EDGE delivers an integrated workflow and ensures the resource estimate has a strong geological foundation. Nearly 90% of those surveyed agreed that Leapfrog EDGE provided this integration and that it improved their confidence in the final result.

Robin Simpson, Principal Consultant (Resource Geology) at SRK Consulting, Russia, told us, “Leapfrog EDGE is a pleasure to use and it is convenient to be able to stay within Leapfrog for many of the tasks I previously had to export to other software. I like the convenience of being linked to the geology model and it is more efficient to update the resource model with fewer hassles importing and exporting files.”

Federico Mera, Resource Geologist at Lundin Gold, Ecuador, had a similar experience, “Leapfrog EDGE is what a modeller geologist always wanted. It simplifies steps and removes the annoying processes that deviate from the main goal of understanding the geology. I’ve used other software to model resources but I never feel entirely comfortable because I’m concerned about importing, exporting, re-importing and changing file formats.”

Leapfrog EDGE’s dynamic updating feature, first introduced in Leapfrog Geo, allows users to add data or revise their interpretations at any stage in the workflow and the changes automatically flow downstream and update. This simple but substantial step enhances how users can manage change as they continue to interpret geology and make use of the latest information.

This dynamic updating is cited as a key advantage by many including Graham Greenway, Group Resource Geologist at Lundin Mining, UK, who says, “One of the most frustrating steps in the resource estimation process is having to run and re-do multiple steps if new data is added. When you add new data to Leapfrog EDGE the process automatically reworks itself.”

A Three Letter Word that Sank a Thousand Mineral Projects

This post was written by Mike O’Brien, Geostatistician Seequent Expert Services (previously ARANZ Geo), based on his experiences working as a consultant on mineral projects

‘AND’ is a logic gate that sneaks up on mineral projects and destroys their value.

‘AND’ is a logical conjunction and, to grossly simplify, it implies the outcome of applying a series of factors in combination is only positive if each of the series of factors is positive. This logic gate controls a lot of things that we do. For example, (Exam passed by Jane) = (Jane goes to school) AND (Jane goes to exam venue) AND (Jane obtained pass mark). All three conditions have to happen for Jane to pass the exam.

The Open Mining Format

By Nicole Doucette

Imagine this: You’re a geologist at a mining company, and you’ve just finished updating your company’s geological model with new drilling results. You now need to pass this model to the mining engineers, so they can redesign a section of the mine. The mining engineers use a different software program than you do though, as it’s an industry standard to use different specialized programs for each part of the mining lifecycle.

However, your software programs are proprietary and not interoperable – meaning they don’t easily share information. They each have a unique file format. Your company has created a custom script to convert from one software to another, so you spend hours running the script and checking the data. You’re wary to run any new software updates, as it could change the file structure and render your script useless. You also have to meticulously check the file to make sure it’s converted correctly – because once the file was corrupted and haul trucks were sent to the wrong location, which was both dangerous and costly.

Instead of being able to focus on your work, you’re losing time every day converting and re-importing files for different programs. Since mining is iterative, you pass files back and forth with other geologists and engineers often. Every time they send you their data, they have to follow this same time-consuming process as well.

Leapfrog 4.0 – Unlocking the value of Structural Data

We’d like to share some of the feedback we’ve received so far from users who are benefiting from Leapfrog 4.0’s new structural modelling tools and workflows. We hope this blog gives you the opportunity to compare your experience with others, motivates you to dive into modelling your structural data yourself or just encourages you to experiment!’

Structural Geology

Leapfrog 4.0 is a major release that introduces an entirely new structural data workflow and tools to import and clean structural data, identify patterns and then incorporate this valuable structural knowledge into your models.

“ One thing I really like is the easy and intuitive nature of loading and choosing the data you want to work with.The speed at which you can get an overall trend-will help in determining the general shape of wireframes (it’s fast). “

Leapfrog Central: What does it mean for your organisation?

By Peter Joynt

In 2003, ARANZ Geo released the first version of Leapfrog. Leapfrog’s implicit modelling engine brought about a paradigm shift in the way geologists generate 3D interpretations. Organisations that have embraced this new technology have realised significant benefits by building dynamic implicit models in less time.

Now, in 2016, we are releasing Leapfrog Central, a model management system that will bring about another paradigm shift, to continuous modelling.

What is continuous modelling? Continuous modelling supports incremental changes to models as data becomes available, and because the development of the model is visible to the wider organisation, decisions can be made based on the latest data and the most current understanding.

Point selection in Leapfrog Geo 3.1

By Peter Joynt

As you may know, we have recently released Leapfrog Geo 3.1 – this new release adds 3D point selection, a relatively simple feature that unlocks a number of new workflows. I am going to show you a few of these workflows – and hopefully it helps identify others that will fit your unique problems.

The point selection tool works in a similar way to interval selection, which has been available in Geo for some time. Interval selection is extremely useful for reclassifying poorly logged intervals and picking vein and dyke segments out of large complex drillhole datasets in 3D. The workflow is based around a simple to use 3D paint brush tool which, when combined with in-scene slicing and query filters, lets you quickly select and re-classify segments. We have now adapted this tool to be used with points, and allowed the creation of new category selection columns on points. Below are three examples of ways point selection can be used in your projects.

 

Selection of collars

Have you ever worked with a large drillhole dataset that has multiple prospects but no column in the database that can be used to separate them? This is a situation where the point selection tool can be useful. You can easily select a subset of drillholes in 3D and assign them a category. On top of this, you can apply query filters to give you flexibility for modelling and visualisation. The selection itself can be carried out directly on the collar table in the Drillhole Data folder.
