Fitzroy Minerals Initiates Advanced Geophysical Survey at Chilean Copper Project

Fitzroy Minerals Inc. has commenced a 750 line-kilometre mobile magnetotelluric heliborne survey at its Caballos Copper Project in Valparaiso, Chile. The survey, conducted by Expert Geophysics Surveys Inc., is expected to cover the entire project area within two days, with interpreted results anticipated in March 2026. This geophysical technology is designed to identify subsurface geologic structures, alteration halos, and contrasting lithologies that could indicate mineralized zones.

The MobileMT system will be complemented by VLF-EM data collection, which provides near-surface electromagnetic information to enhance resolution of shallow geological features. By combining these methods, the survey aims 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 comprehensive approach could significantly advance understanding of the project's subsurface architecture.

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, including areas beneath younger volcanic rocks to the east. The company hopes the survey will help trace the outline of mineralized breccias already intersected through drilling and vector toward the origin of these breccias, which contain clasts of mineralized porphyry rocks. MobileMT is particularly known for identifying electrically conductive sulphides potentially linked to mineralized porphyry intrusive centers, as well as resistive bodies representative of intrusions.

The importance of this survey lies in its potential to significantly enhance exploration efficiency and targeting at the Caballos Copper Project. By providing detailed subsurface imaging without extensive ground disturbance, the heliborne survey represents a cost-effective method for identifying promising exploration targets. The ability to map structures to depths of up to 2 kilometers could reveal previously unknown mineral systems and help prioritize future drilling campaigns.

This geophysical initiative comes at a time when global copper demand continues to grow, driven by electrification trends and renewable energy infrastructure development. Successful identification of mineralized structures at Caballos could position Fitzroy Minerals to potentially contribute to future copper supply. The survey represents a strategic investment in advanced exploration technology that could yield significant geological insights while minimizing environmental impact compared to traditional exploration methods.
