Fitzroy Minerals Inc. (TSXV: FTZ, OTCQX: FTZFF, FSE: C3Y) announced results from a helicopter-borne MobileMT airborne electromagnetic and magnetic survey at its Caballos Project in the Valparaiso Region, Chile. The survey, conducted by Expert Geophysics Services Inc. (EGS), has identified multiple conductivity and resistivity anomalies interpreted as consistent with porphyry-style hydrothermal systems, directly linked to mineralization intersected in 2025 diamond drilling.
The survey covered 694 line-km over approximately 194 km², including a 200 m spacing infill over the Central Target area. Key findings include a large circular conductive feature about 5 km in diameter, interpreted as a porphyry-related hydrothermal system connected to copper-molybdenum-gold-rhenium mineralization at the Chincolco Prospect. Additionally, linear conductive anomalies extend up to 2.5 km south from Chincolco, suggesting potential for significant lateral continuity of mineralization.
Merlin Marr-Johnson, President and CEO, stated: “The MobileMT survey shows that Caballos hosts the type of plumbing architecture and conductive anomalies that are often associated with world-class mineral systems in Chile. The standout anomaly is a huge circular feature about five kilometres across that connects to the sulphide mineralization we intersected in drilling last year. There are also conductive anomalies that suggest the Chincolco sulphide mineralization might continue for several kilometres to the south, just below the surface.”
The survey also identified a prominent north-south conductive corridor extending 14 km along the Pocuro Fault Zone, interpreted as a major crustal-scale permeable structure and potential pathway for mineralizing fluids. Further north, resistivity patterns comparable to those at El Teniente and La Huifa in Chile suggest district-scale mineralizing potential.
Fitzroy plans follow-up with a ground Deep IP survey to gain chargeability information and improve target ranking ahead of drilling. The company aims to use future cash flow from its Buen Retiro Heap Leach operation to fund non-dilutive exploration drilling. EGS has been commissioned for 3D inversion of key areas, and the data will be integrated with geological and geochemical datasets for AI-enhanced processing to refine drill targets.
The MobileMT survey was completed by EGS using their proprietary broadband electromagnetic system designed to resolve deep crustal-scale conductive features. The results provide a robust geophysical framework for exploration targeting across the Caballos property.
Fitzroy Minerals also announced the grant of 5,770,000 stock options to directors, officers, and consultants, exercisable at $0.50 per share until April 29, 2031. The technical information in this release has been reviewed by Dr. Scott Jobin-Bevans, a Qualified Person as defined by NI 43-101.
For further details, refer to the company's news release dated January 13, 2026, regarding drill hole CAB-DDH004A, which intersected 176 m @ 0.31% Cu, 249 ppm Mo, 0.04 g/t Au (0.47% CuEq) from 156 metres. The Caballos Project represents a significant opportunity for Fitzroy Minerals to advance its copper-focused exploration in Chile.
