Validating or improving geological models with magnetic field data is an important part of creating a unified 3D exploration model to guide drill planning. The benefit of the Magnetization Vector Inversion technique, now proven in the field, is its ability to produce results that are consistent with more geological environments than conventional susceptibility modelling.
Deposits may have become harder to find in recent decades, but by eliminating instrument noise, making 3D geophysical inversion an integral part of the exploration process and harnessing the unprecedented computing power of the cloud, Rio Tinto aims to see what is currently hidden.
From validating geology on grassroots project to finding new ore around existing mines, geophysical inversion is taking some of the risk out of high stakes mineral exploration. Recent technology developments have turned inversion into a fast and responsive tool that can be used at every stage to delineate targets with greater speed and accuracy.
Magnetization Vector Inversion (MVI) is a technique introduced by Geosoft to help eliminate erroneous assumptions about magnetization. After a year of application in mineral exploration, project examples confirm that MVI results provide a more reliable representation of subsurface geology.
One of the questions many organizations struggle with is 'where to start' with data management. This article identifies 3 key drivers that can be your first step towards improved exploration data management.
