Fitzroy Minerals Inc. has reported substantial progress at its copper exploration projects in northern Chile, with drilling at the Buen Retiro project intersecting significant copper mineralization over hundreds of meters. The company's latest results from drill hole BRT-DDH045 show 384 meters at 0.22% copper from 4 meters depth, including a higher-grade section of 94 meters at 0.33% copper from 30 meters. These findings provide compelling evidence that Buen Retiro represents a major copper system, according to company leadership.
The importance of this discovery lies in its timing and location within the global copper industry. With discovery rates for new copper deposits declining worldwide, successful exploration in established mining jurisdictions like Chile becomes increasingly valuable. Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, emphasized that "in an industry with decreasing discovery rates Fitzroy aims to leverage potential future cash flow from the proposed Buen Retiro Heap Leach copper operation to fund the continued exploration for major copper deposits in Chile with minimal dilution." This strategy could provide a sustainable exploration funding model in a capital-intensive industry.
Beyond the drilling results, Buen Retiro's geographical advantages significantly enhance its development potential. 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. Its proximity to the coast provides access to a proposed desalination plant with a seawater extraction license, while its location near the mining center of Copiapo offers established mining services and a large labor pool. These infrastructure advantages could reduce development costs and timelines compared to more remote discoveries.
The company is advancing multiple work streams simultaneously. Infill drilling with two diamond drill rigs began in February, with approximately 160 meters of HQ diamond core being drilled daily. This program, anticipated to total approximately 6,000 meters, should be completed in April and will support a maiden mineral resource estimate ahead of a preliminary feasibility study. 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.

Geophysical surveys are also progressing. Fitzroy has contracted Fleet Space Technologies to complete an Exosphere Ambient Noise Tomography survey to image the large-scale subsurface architecture of the project area. This technology aims to identify basement geometry, major structural corridors, and velocity contrasts potentially associated with iron oxide copper-gold mineral systems. At the separate Caballos Copper Project, an airborne Mobile MagnetoTellurics survey has been completed, with data interpretation underway to guide Phase 2 drilling later this year.
The technical work follows rigorous quality assurance protocols. The company's sampling procedures include inserting silica blanks every 20 samples, using certified copper standards from Chilean company Instituto Nacional de Tecnologia Estandarizacion y Metrología Ltda., and implementing pulp duplicates to test analytical accuracy. Quality assurance and quality control samples represent about 12% of total primary core samples. Dr. Scott Jobin-Bevans, an independent qualified person as defined by NI 43-101, has reviewed and approved the technical information in the release.
For the copper market and mining industry, successful exploration in Chile maintains the country's position as the world's leading copper producer at a time when global demand for the metal continues to grow, driven by electrification and renewable energy infrastructure. The combination of promising geology, strategic location, and systematic exploration approach makes Fitzroy's progress noteworthy for investors and industry observers tracking copper supply development.
