Fitzroy Minerals Reports Strong Copper Intercepts at Buen Retiro Project, Advancing Toward Key Milestones
Fitzroy Minerals' latest drilling results and ongoing work at its Chilean copper project signal significant progress toward a maiden resource estimate and economic study, highlighting the project's potential to contribute to global copper supply.
Fitzroy Minerals Inc. has reported significant copper intercepts from its ongoing definition drilling program at the Buen Retiro Copper Project in Chile, marking a crucial step toward completing a maiden mineral resource estimate and initial economic study. The company's two-rig drilling operation continues to intersect substantial mineralization, with recent highlights including drill hole BRT-DDH048 returning 92.5 metres at 0.53% copper from 3.5 metres depth, including a higher-grade zone of 46.0 metres at 0.82% copper.
The drilling program, which has completed 32 holes totaling 5,143 metres in the southwest area of the project, aims to delineate Measured and Indicated Resources for inclusion in a planned Pre-Feasibility Study focusing on a heap leach operation. According to Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, the resource definition drilling is advancing quickly and has intersected many samples that exceed laboratory limits for exploration assay methods, indicating substantial copper presence in the system. The company anticipates completing definition drilling in May, after which rigs will be reallocated to exploration and geotechnical programs.
Beyond drilling, Fitzroy has initiated critical metallurgical test work at SGS Laboratories using a 2,900-kilogram representative sample. The test program will evaluate copper extraction kinetics, heap performance, acid consumption, and recovery potential across three defined geo-metallurgical domains: higher-grade oxide material, lower-grade oxide material, and mixed supergene transition material. This classification framework reflects both deposit geometry and expected metallurgical response from principal copper oxide mineral assemblages.
The company has also completed a regional passive seismic Ambient Noise Tomography geophysical survey across a 25-square-kilometer area using technology from Fleet Space Technologies. Data processing and interpretation are underway, with plans for a higher-resolution survey over priority targets once initial results are analyzed. This geophysical work represents what Marr-Johnson calls "a step forward in the hunt for a major sulphide discovery" at Buen Retiro.
The technical significance of these developments lies in their collective progress toward establishing Buen Retiro's economic viability. The consistent thickness of copper-mineralized packages—approximately 80-90 metres thick in the southwest area with a central higher-grade core—combined with systematic metallurgical testing and advanced geophysical surveying creates a comprehensive foundation for resource estimation. The company's stated strategy involves leveraging potential cash flow from a heap leach operation to fund continued exploration for major copper deposits in Chile with minimal shareholder dilution.
Quality assurance and quality control procedures remain rigorous throughout the exploration process. Core samples are analyzed at ALS-Patagonia laboratory, with approximately 12% of samples dedicated to QA/QC measures including certified copper standards from Chilean company Instituto Nacional de Tecnologia Estandarizacion y Metrologia Ltda. The technical information has been reviewed and approved by independent Qualified Person Dr. Scott Jobin-Bevans, who verified data including sampling, analytical, and test results.
As global copper demand continues to grow amid energy transition trends, successful development of projects like Buen Retiro could contribute to future supply. The project's location in Chile's established mining region of Copiapó, combined with its oxide-dominated mineralization suitable for heap leaching, positions it as a potentially lower-capital-intensity development opportunity compared to deeper sulphide deposits requiring conventional milling.
