This presentation outlines the methodology and exploration value of structural modelling from airborne MobileMT data, emphasizing how broadband natural-field total-field electromagnetic measurements can be used to detect, resolve, and model mineralization-controlling conductive (or resistive) structures from shallow to deep levels. It highlights key technical advantages of MobileMT, including three-component total-field sensing, a broad frequency spectrum that improves depth resolution and frequency selection for inversion. The workflow presented extends from apparent conductivity and inverted resistivity grids through adaptive anomaly-axis detection and tracing, and database integration to the creation of 3D conductive-structure models. Case studies from the Athabasca region and other uranium-focused projects demonstrate that these models correlate well with geology and drilling, including graphite- and sulphide-bearing corridors associated with uranium mineralization, showing that MobileMT structural modelling can materially improve targeting and drill planning for structurally controlled deposits such as uranium, epithermal and orogenic gold, and IOCG systems.
