Fitzroy Minerals Intersects 384 m @ 0.23% Cu from 4 m, including 94 m @ 0.33% Cu from 30 m, Buen Retiro Copper Project, Chile (TheNewswire) Vancouver, British Columbia – TheNewswire – March 20, 2026 – Fitzroy Minerals Inc. (TSXV: FTZ, OTCQX: FTZFF, FSE: C3Y) (“Fitzroy” or the “Company”) is pleased to provide an update on exploration progress at its Buen Retiro and Caballos copper projects (the “Copper Projects”) in northern Chile. Buen Retiro Highlights: Drill hole BRT-DDH045: 384 m @ 0.22% Cu from 4 m, including 94 m @ 0.33% Cu from 30 m. Infill drilling underway to allow for a maiden mineral resource estimate ahead of a PFS. A 2,800 kg bulk sample ready for heap leach metallurgical test work at SGS Laboratories. Fleet Space Technologies passive seismic survey to start soon. At the Caballos Copper Project, the airborne MobileMT geophysical survey is complete, with data currently being interpreted. Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, commented: “Drill hole 45 intersected copper in two distinct mineralizing styles on a large scale in the North area of the Buen Retiro property. It is also located three kilometres north-northeast of the high-grade copper oxide mineralization in the Southwest area. Combined with large, coincident geophysical anomalies, there is now compelling evidence that Buen Retiro is a major copper system. Crucially, Buen Retiro is at low elevation, on a brown-fields site four kilometres from the Pan-American Highway and associated high voltage transmission lines, close to the coast where a proposed desalination plant has a seawater extraction licence, and close to the mining centre of Copiapo with its mining services and large labour pool. 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.” Buen Retiro Cu-(Co) Project At Buen Retiro, results from diamond drill holes 44 and 45 from the Phase 1 program are reported in Table 1. Separately, infill drilling with two diamond drill rigs started in February and approximately 160 m of HQ diamond core is being drilled per day. Drill holes 46 through 60 have been completed and are being logged and cut, with samples sent for assay on an ongoing basis. Half core from the infill drill holes is being aggregated to comprise representative bulk samples defined on mineralogical characteristics and the target total weight of about 2,800 kg of mineralized material for metallurgical test work has been reached. Metallurgical tests for the Buen Retiro Heap Leach Project will be carried out by SGS Laboratories (“SGS”), starting in late March. Remaining half core is quartered, with one quarter being sent for assay and the last quarter being stored in core trays. The infill drilling program, anticipated to be approximately 6,000 m of drilling, should be completed in April. After the infill drilling is complete, one rig will focus on exploration drilling (NQ core), and the other drill rig will be released. A passive seismic, Ambient Noise Tomography (“ANT”) ground geophysical survey is about to start which will assist with the litho-structural interpretation, supporting sulphide drill-targeting at depth. The exploration drilling program will be a minimum of 8,000 m with flexibility to increase to 15,000 metres. Drilling Results As previously reported (news release January 13, 2026), in the North area of the Buen Retiro Project, drilling has identified a copper-sulphide mineralized trend extending for approximately 1 kilometre north of the historical Manto Negro Mine open pit, hosted within a volcanic sequence dominated by andesitic rocks, interbedded with volcanic breccias and tuffs (Figure 1).

Drill hole BRT-DDH045 is particularly interesting as the first 100 metres intersected a zone of stockwork intercalated with minor breccias from the start of fresh rock at four metres. Figure 2.

Copper mineralization (chalcopyrite) is very consistent throughout the hole, reflected in the results of 384 metres @ 0.23% Cu from four metres, including 94 metres @ 0.33% Cu from 30 metres. Drill hole BRT-DDH044 intersected a series of low-grade intersections, the best interval being 10 metres @ 0.30% Cu, from 142 metres. Geophysics Fitzroy Minerals has contracted Fleet Space Technologies to complete an Exosphere Ambient Noise Tomography (ANT) geophysical survey. The survey is likely to be carried out in two stages: an initial regional ANT survey (Phase 1) followed by a t
