Fitzroy Minerals Inc. has initiated a 750 line-kilometre mobile magnetotelluric heliborne survey at its Caballos Copper Project in Valparaiso, Chile, conducted by Expert Geophysics Surveys Inc. The survey, scheduled to cover the entire project area within two days, will utilize MobileMT technology designed to identify subsurface geologic structures, alteration halos, and contrasting lithologies. Complementary VLF-EM data will provide near-surface electromagnetic information for enhanced resolution of shallow features, with interpreted results anticipated in March 2026.
Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, explained that the MobileMT data is expected to generate a three-dimensional image of the Caballos Project area, including regions beneath younger volcanic rocks to the east. 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. According to Marr-Johnson, MobileMT is recognized for detecting electrically conductive sulphides potentially associated with mineralized porphyry intrusive centers and resistive bodies representative of intrusions.
The combined geophysical methods are projected to identify deep-seated faults, lithological contacts, and structures controlling mineral systems from surface to depths of approximately 1 to 2 kilometers, depending on the conductivity distribution of the local geology. This survey represents a significant step in Fitzroy Minerals' exploration strategy, as detailed in the company's periodic filings available at https://www.sedarplus.ca.

The implications of this survey extend beyond immediate data collection, as successful identification of subsurface features could guide future drilling campaigns and resource estimation at the Caballos Project. In a region where copper demand continues to grow for renewable energy and electrification infrastructure, advanced exploration techniques like MobileMT offer a non-invasive means to de-risk early-stage projects. The ability to map structures up to 2 kilometers deep provides a competitive advantage in locating potential mineralization that might otherwise remain undetected using traditional methods.
Forward-looking statements in the release caution that actual results may differ due to factors including exploration risks, regulatory challenges, and market conditions, as outlined in the company's regulatory filings. The survey's March 2026 timeline aligns with Fitzroy Minerals' phased exploration approach, where geophysical data will inform subsequent decision-making. For investors and stakeholders, the deployment of this technology signals a methodical investment in understanding the project's geology before committing to more capital-intensive activities.
