Fitzroy Minerals Inc. has announced results from a helicopter-borne MobileMT airborne electromagnetic and magnetic survey at its Caballos Copper Project in Chile's Valparaiso Region, identifying several large conductive anomalies interpreted to be consistent with porphyry-style hydrothermal systems. The survey, conducted by Expert Geophysics Services Inc. (EGS), covered 694 line-km over approximately 194 km², including a 200 m spacing infill over the Central Target area.
The standout feature is a large circular conductive anomaly approximately 5 km in diameter, interpreted as a porphyry-related hydrothermal system directly connected to copper-molybdenum-gold-rhenium mineralization intersected in 2025 drilling at the Chincolco Prospect. Additionally, linear conductive anomalies extending up to 2.5 km southeast from drill hole CAB-DDH004A suggest potential southward continuation of mineralization beneath thin volcanic cover.
Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, 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.” He noted that the company plans to follow up with further integrated data processing and a ground Deep IP survey to gain chargeability information and improve target ranking ahead of drilling.
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 potentially serving as a pathway for mineralizing fluids. Further north, resistivity patterns characteristic of hydrothermal breccia-associated porphyry systems were observed, comparable to those at major deposits like El Teniente and La Huifa.
Fitzroy Minerals will integrate the MobileMT data with geology, geochemistry, and drilling results to define priority drill targets. A 3D inversion of key areas has been commissioned, and a Deep IP survey is planned for Q2 2026 to upgrade conductivity anomalies into ranked drill targets. The company aims to fund non-dilutive exploration drilling through future cash flow from the Buen Retiro Heap Leach operation.
The qualified person for the technical information, Dr. Scott Jobin-Bevans (P.Geo., Ph.D., PMP), has reviewed and verified the data. The company also announced the grant of 5,770,000 stock options to directors, officers, and consultants at $0.50 per share, exercisable until April 29, 2031.
