Fitzroy Minerals Inc. has commenced a 750 line-kilometer mobile magnetotelluric heliborne survey at its Caballos Copper Project in Valparaiso, Chile. The survey, conducted by Expert Geophysics Surveys Inc., is scheduled for completion within two days, with interpreted results expected by March 2026. This geophysical investigation represents a significant step in mineral exploration, employing advanced technology to gather subsurface data that could reveal economically viable copper deposits.
The MobileMT technology is designed to identify subsurface geologic structures, alteration halos, and contrasting lithologies. When combined with complementary VLF-EM data, which provides near-surface electromagnetic information, the methods offer increased resolution of shallow features. Together, these techniques can identify deep-seated faults, lithological contacts, and structures controlling mineral systems from surface to depths of approximately 1 to 2 kilometers, depending on local geology conductivity. This comprehensive approach allows exploration beneath younger volcanic rocks that might otherwise obscure mineral targets.
Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, stated that the MobileMT data is expected to provide a three-dimensional image of the Caballos Project area. The survey aims to trace the outline of mineralized breccias already intersected through drilling and help vector toward the origin of these breccias, which contain clasts of mineralized porphyry rocks. MobileMT is particularly known for identifying areas of electrically conductive sulphides potentially linked to mineralized porphyry intrusive centers, and resistive bodies representative of intrusions.
The importance of this survey extends beyond Fitzroy Minerals' specific project. As global demand for copper continues to grow, driven by electrification and renewable energy infrastructure, efficient exploration methods become increasingly critical. The ability to accurately map subsurface structures to significant depths without extensive ground disturbance represents an advancement in mineral exploration technology. Successful identification of mineralized zones could lead to more targeted drilling programs, reducing environmental impact and exploration costs while increasing discovery efficiency.
For investors and industry observers, the survey results will provide important data points about the Caballos Project's potential.

This geophysical survey represents a methodical approach to mineral exploration that balances technological advancement with responsible resource development. The data gathered will inform future exploration decisions at the Caballos Project and contribute to the broader understanding of Chile's mineral potential. As copper remains essential for global infrastructure and clean energy transitions, efficient exploration methods like MobileMT surveys play a crucial role in identifying future resources while minimizing environmental disturbance through targeted investigation.
