Partnering with industry leaders for success

Our vision is for an open ecosystem where data is shared securely between ioGAS™, IMDEXHUB-IQ™, and other leading geoscience and GIS software programs.

ioGAS™ is a leading exploratory data analysis software application developed specifically for the resources industry. Traditional methods to analyse results could take many hours and is always prone to human error, ioGAS™ in comparison can generate accurate results in a fraction of the time. Over the past decade a wide range of visual analytics and advanced quantitative tools have been developed to obtain a greater insight into the underlying structure of your data.

Leapfrog Live Link

IMDEX and SEEQUENT have combined to produce the ioGAS™-Leapfrog live link for rapid 3D visualisation of geochemical data in real-time. Geoscientific data can be analysed in ioGAS and then visualised and modelled in the 3D environment using Leapfrog Geo. Geochemistry parameters can be added as new attributes and transformed into 3D interpolants for enhancing geological models.

The ioGAS™ Link is sold and licensed as a separate add-on to the Leapfrog Geo software. The link will only run with an active licence of Leapfrog Geo, enabled for the ioGAS™ Link. You will also need Leapfrog Geo v1.3 or later and ioGAS™ v5.0 or later. For further information including how to obtain a trial version of the Leapfrog Geo software or to purchase the ioGAS™ Link please contact your local Leapfrog sales team.

Unlock the power of your geochemical data with ioGAS. A two day interactive workshop and delve into the world of geochemical data analysis. Includes:

  • Real-Life Case Studies: Immerse yourself in practical scenarios where you’ll explore lithogeochemical, alteration, and pathfinder trends using ioGAS workflows on data from real exploration projects.
  • Bold Machine Learning: Discover how ioGAS leverages cutting-edge Machine Learning techniques. Bid farewell to the black box — our goal is to empower you, not intimidate you!
  • Geochemistry Unleashed: We’re shining a spotlight on geochemistry! Prepare for a deep dive into this critical domain to enhance mineral exploration targeting and orebody knowledge.
  • Beyond the Basics: ioGAS isn’t just about data — it’s about value. Learn how to extract insights that drive better decisions on your project.


ioGAS Fundamentals

covers the basics of the ioGAS software through to more advanced workflows and is designed for new users, intermittent users who need a refresher and regular users who would like to gain a better understanding of what ioGAS can do for them. Topics covered include data validation/QC tools, univariate and multivariate plots, downhole and line plots, maps and images, plot enhancements, a rundown of the multiple export tools allowing you to move data and products seamlessly into other software, and the creation and use of classification diagrams. It is appropriate for geologists, geochemists, metallurgists and geoscience managers


ioGAS Advanced Workflows

covers advanced ioGAS functions and is designed for regular users who would like to develop their own interpretation routines and expand their geoscience data interpretation skillset. This course demonstrates the advanced techniques offered by ioGAS to model the behaviour of geochemical, lithological, alteration and geometallurgical data as well as interpretation of an integrated dataset; Combining lab-based geochemistry data with pXRF geochemistry, spectral mineralogy, structural geology and downhole geophysics data. The following topics will be covered in this Module: K-means clustering, principal components, discrimination projection and self-organising maps and prioritise exploration or domaining of targets from auto-outlier detection tools.
