1. VOXI Earth Modelling A quick introduction to Geosoft’s inversion solutions for Company X

2. Explorers choose Geosoft

3. “I felt like I had been taken from the Stone Age to the Space Age over a cup of coffee.” Robert Carrington President and CEO of Colombian Mines

4. Traditional geophysical exploration techniques provide a visual interpretation directly from the data. This works well for visualizing near-surface features. What’s the big deal about inversion? You need to use geophysical inversion to help see the subsurface picture by creating quantitative models.

6. Geosoft VOXI innovations Cloud computingAdvanced inversion developments Integrated collaboration

7. The VOXI cloud advantage Quick on-demand inversion processing from any laptop Secure encrypted transfer and no identifiable location data are sent Cloud processing does the heavy lifting and automatically adds processing power when required Save time - results are available in minutes, not days Productivity keep working away while running inversions Rapid iteration allows for a more scientific modelling approach

14. Customer story Using geophysical inversion modelling to deliver new targets in the Yukon

15. VOXI Customer story Exploration site

16. Unconstrained vs. IRI VOXI Customer story Unconstrained susceptibility inversion Geophysical model is overly smooth, crossing several geological boundaries. Iterative Reweighting Inversion (IRI) Geophysical model correlates to known geology

17. Realistic models VOXI Customer story Susceptibility inversion model constrained with drillhole data Iterative Reweighting Inversion (IRI) Geophysical model correlates to known geology

18. “The beauty of Geosoft VOXI is that as you learn about a property, you can add those measurable rock properties to the model and constrain it even further. It’s a very quick and efficient way to assess large tracts of ground given the right exploration target.” Mike McCuaig Geologist, Terralogic Exploration

19. Reduces exploration risk and improves decision-making Lightning-fast and intuitive More reliable representation of subsurface geology Integrated and collaborative Improved prospecting and drill targeting
