Fitzroy Minerals Inc. has reported significant exploration progress at its Buen Retiro and Caballos copper projects in northern Chile, with drilling results indicating substantial copper mineralization that could position the company to address industry challenges. The announcement comes as global copper discovery rates decline while demand for the essential metal continues to grow across electrification and renewable energy sectors.
At the Buen Retiro project, diamond drill hole BRT-DDH045 intersected 384 meters grading 0.22% copper from 4 meters depth, including a higher-grade interval of 94 meters at 0.33% copper from 30 meters. According to Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, this intersection revealed copper in two distinct mineralizing styles on a large scale in the North area of the property. The hole is located three kilometers north-northeast of previously identified high-grade copper oxide mineralization in the Southwest area.
The company has initiated an infill drilling program with two diamond drill rigs operating since February, drilling approximately 160 meters of HQ diamond core daily. This program, anticipated to total approximately 6,000 meters, aims to support a maiden mineral resource estimate ahead of a preliminary feasibility study. Drill holes 46 through 60 have been completed with samples being processed for assay results.
A 2,800-kilogram bulk sample has been prepared for heap leach metallurgical test work at SGS Laboratories, with testing scheduled to begin in late March. The company plans to leverage potential future cash flow from a proposed Buen Retiro heap leach copper operation to fund continued exploration for major copper deposits in Chile with minimal dilution to shareholders.
The strategic location of Buen Retiro represents a significant advantage for potential development. The project sits at low elevation on a brown-fields site just four kilometers from the Pan-American Highway and associated high-voltage transmission lines. It is also close to the coast where a proposed desalination plant has a seawater extraction license and near the mining center of Copiapo with established mining services and labor pools.
Fitzroy Minerals has contracted Fleet Space Technologies to complete an Exosphere Ambient Noise Tomography geophysical survey to assist with litho-structural interpretation and support sulphide drill-targeting at depth. The Phase 1 survey is about to begin and aims to image the large-scale subsurface architecture of the project area.
Drilling has identified a copper-sulphide mineralized trend extending approximately one kilometer north of the historical Manto Negro Mine open pit. The mineralization is hosted within a volcanic sequence dominated by andesitic rocks interbedded with volcanic breccias and tuffs.

At the Caballos Copper Project, an airborne Mobile MagnetoTellurics geophysical survey has been completed with data interpretation ongoing. Phase 2 drilling is scheduled for later in the year once geophysical data is integrated into the company's geological model.
The company maintains rigorous quality assurance procedures, with approximately 12% of total primary core samples dedicated to quality control. Certified copper standards from Chilean company Instituto Nacional de Tecnologia Estandarizacion y Metrología Ltda. are used to evaluate laboratory analysis accuracy. Independent geological consultant Dr. Scott Jobin-Bevans has reviewed and approved the technical information in accordance with NI 43-101 standards.
These developments occur within a challenging exploration environment where major copper discoveries have become increasingly rare despite growing global demand. The combination of promising geological results, strategic location advantages, and systematic exploration approach positions Fitzroy Minerals to potentially contribute to future copper supply in a market where new discoveries are critical for meeting projected demand from electrification and renewable energy infrastructure development worldwide.
