How Leapfrog Geo helped improve geological understanding and productivity at Edna May Gold Mine, Western Australia

In 2014, leading Australian gold miner, Evolution Mining, first introduced Leapfrog Geo to generate a geological model for the 2014 Mineral Resource Estimation, a major change compared to previously used explicit methods. Based on this success, Leapfrog Geo was then introduced to rapidly update the Grade Control (GC) block model.

Hans Andersen, Group Resource Geologist, Evolution Mining, says, “Using Leapfrog Geo we are able to model highly complex geology, giving improved representation of the various geological units. For the past 18 months Leapfrog Geo has also supplemented our grade control process enabling the dynamic updating of our GC block model. This has freed up significant modelling time and allows staff to concentrate on other high value geological activities.”

Take control of your geological modelling in 2018

Are you energised and excited about the projects underway in 2018? Are the tools you use for modelling helping you to achieve your goals? Are you happy to recommend them?

Recommending a solution to others is the number one proof of satisfaction. If you’re not happy to recommend your current solution, you’re not satisfied. Leapfrog’s 2017 annual survey revealed 95% of users surveyed would recommend Leapfrog to a friend or colleague.

Seriously satisfied

As you can see from the satisfaction scores below, the majority of Leapfrog users surveyed are ‘satisfied’, and a large proportion of those ‘satisfied’ users are ‘very satisfied’

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.

3D geological mapping: From 2D GIS maps to 3D modelling

By Antonio Celis

phot 1


Traditionally, geoscientists have translated their field data collection efforts into a digital version of a geological map, which is typically built using GIS software (e.g. ArcGIS). Consequently most companies will have large archives loaded with GIS information from their projects. With more companies now choosing to collect their field data using electronic devices it ultimately results in a large repository of GIS data.

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). “

Sula Iron & Gold Case Study – use of Leapfrog Geo’s movie function as a key marketing tool

Multi-commodity exploration company Sula Iron and Gold plc have used Leapfrog Geo’s movie function as a key marketing tool in the Ferensola Gold Project, Sierra Leone.

Using the movie function, Sula’s Non-Executive Technical Director, Howard Baker, has produced an impressive presentation to communicate target scale and to lift the project’s profile to the wider investment community.

Client Paper: Rockmass classification – different ways of interpreting a 3D Leapfrog Geo model

We are grateful to Davi Newton Pinheiro da Costa Gomes, Geologist Engineer – Rock Mechanic at AngloGold Ashanti, for producing this paper. The paper is provided in the original Portuguese as well as English  , and aims to show how the rockmass classification of the mine known as Orebody V was performed, as well as different ways of interpreting a 3D geotechnical model.

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.

Geotechnical data collection and presentation – It starts and ends with a vision

We’d like to share this article by Louie Human and Ben Jupp, Principal and Senior Consultants at SRK. The article gives some great advice on best practice approaches to Data Collection as the first step towards minimising uncertainty and input into the advanced technical assessment and design of a caving operation. The article goes on to stress the importance of using 3D visualisation tools such as Leapfrog in engineering, to make the understanding of the data in a spatial context possible.

The authors outline why combining robust data collection with software toolsets that visualise, interrogate and develop geotechnical models is so important and how these ultimately feed into the mine design and decision making process and impact on the safety and economics of recovery.

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.

Collar selection
