Fitzroy Minerals Begins MobileMT Heliborne Survey at Caballos Copper Project
Vancouver, British Columbia — February 11, 2026 — Leads & Copy —
Fitzroy Minerals Inc. (TSXV: FTZ, OTCQX: FTZFF; FSE: C3Y) announced that Expert Geophysics Surveys Inc. has started a planned 750 line-kilometre mobile magnetotelluric (“MobileMT”) heliborne survey at the Caballos Copper Project in Valparaiso, Chile. The company expects interpreted results from the survey in March 2026.
The survey will cover the entirety of Fitzroy’s Caballos Copper Project within two days.
MobileMT is a geophysical technology that aids in the identification of subsurface geologic structures, alteration halos, and contrasting lithologies. Complementary VLF-EM data should yield increased resolution of shallow features.
Combining the methods should identify deep-seated faults, lithological contacts, and structures controlling mineral systems from surface to a depth of approximately 1 km to 2 km, dependent on the conductivity distribution of the local geology.
Merlin Marr-Johnson, President and CEO of the Company, said that the company expects the Mobile MT data will provide a three-dimensional image of the Caballos Project area, including under the younger volcanic rocks to the east. He hopes that the survey will assist in tracing the outline of the mineralized breccias already intersected through drilling. Further, Marr-Johnson said he hopes the survey helps 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, according to Marr-Johnson.
Fitzroy Minerals is focused on exploring and developing copper-focused mineral assets with substantial upside potential in the Americas. The Company’s current property portfolio includes the Buen Retiro Copper Project located near Copiapó, Chile, the Caballos Copper and Polimet Gold-Copper-Silver projects located in Valparaiso, Chile, the Taquetren Gold Project located in Rio Negro, Argentina, and the Caribou Project in British Columbia, Canada. Fitzroy Minerals’ shares are listed on the TSX Venture Exchange under the symbol FTZ and on the OTCQB under the symbol FTZFF.
