Fitzroy Minerals Inc. has commenced a 750 line-kilometer mobile magnetotelluric (MobileMT) heliborne survey at its Caballos Copper Project in Valparaiso, Chile. The survey, conducted by Expert Geophysics Surveys Inc., is scheduled to cover the entire project area within two days, with interpreted results anticipated in March 2026. This initiative represents a significant step in the company's exploration strategy, utilizing advanced geophysical technology to gain a deeper understanding of the property's subsurface geology.
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 are expected to yield increased resolution of shallow features. The integrated approach aims to map deep-seated faults, lithological contacts, and structures controlling mineral systems from the surface to depths of approximately 1 to 2 kilometers, depending on the conductivity distribution of the local geology. This depth penetration is crucial for exploring buried mineral deposits that may not be visible at the surface.
Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, stated that the company expects the MobileMT data to provide a three-dimensional image of the Caballos Project area, including areas beneath younger volcanic rocks to the east. The survey is hoped to assist in tracing the outline of mineralized breccias already intersected through drilling and to vector toward the origin of these breccias, which contain clasts of mineralized porphyry rocks. Marr-Johnson noted that MobileMT is known for identifying areas of electrically conductive sulphides potentially linked to mineralized porphyry intrusive centres, as well as resistive bodies representative of intrusions.
The importance of this survey lies in its potential to de-risk and guide future exploration efforts at the Caballos Copper Project. By providing a detailed subsurface map, the data could help prioritize drill targets, potentially leading to more efficient and cost-effective exploration. In a global context where copper demand is rising due to its essential role in electrification and renewable energy infrastructure, successful exploration in jurisdictions like Chile—a major copper producer—could contribute to future supply.

The survey's outcomes, expected next month, will be closely watched by the mining industry as an example of modern geophysical application in copper exploration. While forward-looking statements involve risks and uncertainties, as detailed in the company's regulatory filings, the use of such technology underscores the evolving methods in mineral exploration aimed at discovering resources necessary for the global energy transition.
