Fitzroy Minerals Inc. (TSXV: FTZ, OTCQB: FTZFF) announced on February 11, 2026, that Expert Geophysics Surveys Inc. has commenced a planned 750 line-kilometre mobile magnetotelluric (MobileMT) heliborne survey at the Caballos Copper Project in Valparaiso, Chile. The survey, which will cover the entire property within two days, is expected to yield interpreted results by March 2026.
MobileMT is a leading geophysical technology that aids in identifying subsurface geologic structures, alteration halos, and contrasting lithologies. The survey also incorporates complementary VLF-EM data, which provides near-surface electromagnetic information to enhance resolution of shallow features. Combining these methods is designed to identify deep-seated faults, lithological contacts, and structures controlling mineral systems from the surface to a depth of approximately 1 km to 2 km, depending on the conductivity distribution of the local geology.
Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, commented: 'We expect the MobileMT data will provide a three-dimensional image of the Caballos Project area, including under the younger volcanic rocks to the east. We hope the survey will assist us in tracing the outline of the mineralized breccias already intersected through drilling. Further, we hope the survey helps us to vector towards the origin of the mineralized breccias that themselves contain clasts of mineralized porphyry rocks. MobileMT is known for identifying areas of electrically conductive sulphides potentially linked to mineralized porphyry intrusive centres, and resistive bodies representative of intrusions.'
The Caballos Copper Project is part of Fitzroy Minerals' portfolio focused on copper assets in the Americas. The company also holds the Buen Retiro Copper Project near Copiapo, Chile, the Polimet Gold-Copper-Silver project in Valparaiso, Chile, the Taquetren Gold Project in Rio Negro, Argentina, and the Caribou Project in British Columbia, Canada.
