Fitzroy Minerals Inc. (TSXV: FTZ, OTCQX: FTZFF, FSE: C3Y) has released results from a helicopter-borne MobileMT airborne electromagnetic and magnetic survey at its Caballos Project in the Valparaiso Region of Chile. The survey identified multiple conductivity and resistivity anomalies interpreted to be consistent with porphyry-style hydrothermal systems and directly connected to copper-molybdenum-gold mineralization intersected in 2025 diamond drilling.
The survey covered approximately 194 km² with 694 line-km flown, including a 200 m spacing infill over the Central Target area. A standout feature is a large circular strongly conductive anomaly approximately 5 km in diameter, interpreted as a porphyry-related hydrothermal system connected to copper-molybdenum-gold-rhenium mineralization at the Chincolco Prospect. Linear conductive anomalies were also identified, extending up to 2.5 km southeast from mineralized drill hole intercepts, suggesting continuity of sulphide mineralization under 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. 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 plans to follow up with further integrated data-processing and a ground Deep IP survey ahead of drilling.
The survey was completed by Expert Geophysics Services Inc. (EGS) using the proprietary MobileMT broadband electromagnetic system. EGS interpreted the conductive zones as representing structurally controlled hydrothermal alteration and sulphide development consistent with a porphyry-related mineralizing environment. A prominent north-south conductive corridor extending 14 km spatially coincident with the Pocuro Fault Zone was also identified, interpreted as a major crustal-scale permeable structure and potential pathway for mineralizing fluids.
Additionally, resistivity patterns in the northern part of the survey block were compared to those at major deposits like El Teniente and La Huifa in Chile, supporting the interpretation of a district-scale mineralizing system. Fitzroy plans to complete a 3D inversion of key areas, integrate data through AI-enhanced processing, and conduct a Deep IP survey in Q2 2026 to upgrade conductivity anomalies into ranked drill targets.
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. The technical information in this release was reviewed and approved by Dr. Scott Jobin-Bevans (P.Geo., Ph.D., PMP), a Qualified Person under NI 43-101.
