Creating an easily updatable Mined Geology Model in Leapfrog Geo

I was asked the other day – can you filter the model for the mined / unmined material in Leapfrog. This got me thinking – the answer is yes but doing it once and only once is a lot of work to get a single result. If we flag a model as mined/unmined today, then tomorrow the result is wrong as we have mined some more. So I asked myself “Is there a way to create a mined model that is easily updated?” There is! It has been a while since I did a ‘how to’ post so I figured this might be a good topic to cover.

In Leapfrog Geo the terminology of the geology modelling process and workflow can easily impose a straitjacket on your thinking – create a geology model using erosion, deposition and intrusion surfaces. What you are in fact creating is a domain model using cutting, covering and slicing surfaces. Remove the geology straitjacket and you will see the domaining process can be used for anything. In this case we can use the cutting (erosion) and covering (deposition) surfaces to cut in a mined/unmined model. Then we can evaluate this model against the drilling, geology models and resource models to flag out the mined material.

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

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.

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.

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

By Antonio Celis

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.

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.
