Fitzroy Minerals Inc. has announced the results of a helicopter-borne MobileMT airborne electromagnetic and magnetic survey at its Caballos Project in Chile's Valparaíso Region. The survey, conducted by Expert Geophysics Services Inc. (EGS), identified multiple conductivity and resistivity anomalies consistent with porphyry-style hydrothermal systems, directly connected to copper-molybdenum-gold-rhenium mineralization intercepted 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 conductive anomaly approximately 5 km in diameter, interpreted as a porphyry-related hydrothermal system linked to mineralization at the Chincolco Prospect. Additionally, linear conductive anomalies connected to Chincolco drill intercepts suggest potential southward continuation for 2.5 kilometers.
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 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.” He added that the company will follow up with further integrated data processing and a ground Deep IP survey to improve target ranking ahead of drilling.
The survey also identified a prominent north-south conductive corridor extending approximately 14 km along the Pocuro Fault Zone, interpreted as a major crustal-scale permeable structure and potential pathway for mineralizing fluids. In the northern survey block, resistivity patterns characteristic of hydrothermal breccia-associated porphyry systems were observed, comparable to those at El Teniente and La Huifa deposits in Chile.
EGS has been commissioned to complete a 3D inversion of key areas, and a Deep IP survey is planned for Q2 2026 to gain chargeability information on sulphides and alteration mineralogy. The company aims to upgrade conductivity anomalies into ranked drill targets. Fitzroy Minerals also granted 5,770,000 stock options to directors, officers, and consultants at $0.50 per share until April 29, 2031.
Dr. Scott Jobin-Bevans, a Qualified Person as defined by NI 43-101, has reviewed and approved the technical information in this release. The company is focused on copper exploration in the Americas, with projects in Chile, Argentina, and Canada.
