Fitzroy Minerals Inc. (TSXV: FTZ, OTCQX: FTZFF, FSE: C3Y) has announced results from a helicopter-borne MobileMT airborne electromagnetic and magnetic survey over its Caballos Project in the Valparaiso Region, Chile. The survey, completed by Expert Geophysics Services Inc. (EGS), identified multiple conductivity and resistivity anomalies interpreted as consistent with porphyry-style hydrothermal systems and connected 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. A standout feature is a large circular strongly conductive feature approximately 5 km in diameter, interpreted as a porphyry-related hydrothermal system directly linked to copper-molybdenum-gold-rhenium mineralization identified by drilling at the Chincolco Prospect in 2025. Additionally, linear conductive anomalies connected to Chincolco mineralized drill hole intercepts suggest a potential southwards continuation for 2.5 kilometres.
Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, commented: “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 identified a prominent north-south conductive corridor extending approximately 14 km across the project area, spatially coincident with the mapped trace of the regional Pocuro Fault Zone. EGS interprets this as a major crustal-scale permeable structure, potentially a pathway for mineralizing magmatic fluids. Further north, resistivity patterns characteristic of hydrothermal breccia-associated porphyry systems were identified, comparable to those at El Teniente and La Huifa in Chile.
Fitzroy Minerals plans to follow up with a 3D inversion of key areas by EGS, a deep Induced Polarization (IP) survey in Q2 2026 to gain chargeability information, and integration of all datasets through AI-enhanced processing to refine drill targets. The company aims to fund non-dilutive exploration drilling with future cash flow from the Buen Retiro Heap Leach operation.
The company 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.
