(TSXV: FTZ, OTCQX: FTZFF, FSE: C3Y) (“Fitzroy” or the “Company”) ispleased to provide an update on exploration progress at its BuenRetiro and Caballos copper projects (the “Copper Projects”) innorthern 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 mineralresource estimate ahead of a PFS. - A 2,800 kg bulk sample ready for heap leachmetallurgical test work at SGS Laboratories. - Fleet Space Technologies passive seismic survey tostart 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 BuenRetiro Project, drilling has identified a copper-sulphide mineralizedtrend extending for approximately 1 kilometre north of the historicalManto Negro Mine open pit, hosted within a volcanic sequence dominatedby andesitic rocks, interbedded with volcanic breccias and tuffs(Figure 1). - Figure 1. Long-section (looking east) and diamond drillhole results, Buen Retiro, Copiapó, Chile. - Click Image To View Full Size Results from drill holes 44 and 45 are shown in Table1. Drill hole BRT-DDH045 is particularly interesting as the first 100metres intersected a zone of stockwork intercalated with minorbreccias from the start of fresh rock at four metres. - Figure 2. Plan map with location of drill holes, BuenRetiro, Copiapó, Chile(UTM WGS 84 19S). - Click Image To View Full Size The drill hole then transitioned into aCandelaria-style stratiform system for a further 284 metres. Coppermineralization (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 30metres. Drill hole BRT-DDH044 intersected a series of low-gradeintersections, the best interval being 10 metres @ 0.30% Cu, from142 metres. Geophysics Fitzroy Minerals has contracted Fleet SpaceTechnologies to complete an Exosphere Ambient Noise Tomography (ANT) geophysical survey. The survey is likely to be carried out in twostages: an initial regional ANT survey (Phase 1) followed by atargeted infill survey (Phase 2), subject to results obtained in Phase1. The Phase 1 survey is about to start and aims to image thelarge-scale subsurface architecture of the Project area, includingbasement geometry, major structural corridors, and velocity contrastspotentially associated with IOCG mineral systems. Following completionand interpretation of the regional survey it might be beneficial toadvance to the Phase 2 infill survey, which would focus on refiningtargets and increasing resolution in areas of interest identified inPhase 1.

Phase 2drilling is scheduled for later in the year once the geophysical datais integrated into the Company’s geological model. Buen Retiro Core Sampling Procedures,Laboratory and QA/QC Buen Retiro drill core, in labelled and secured woodencore trays, is picked up from the drilling site by Company personneland transported by truck from the drill rig to the core processingfacility in Copiapó. Core lengths are checked,after which geotechnical logging is performed. Using an electric core cutting diamond blade saw,primary half core samples are collected from HQ- or NQ-sized drillcore with the remaining half-core stored in the original wooden coretrays at the rented core storage warehouse in Cuesta Cardones, southof Copiapó. A silica blank is inserted every 20 samples (~20 m); ablank is always inserted immediately after a section that containsnative copper. Pulp duplicates are randomly selected in proportion tothe number of samples from each drill hole and inserted into thesample stream along with high-, medium-, and low-grade copperstandards. Sample identifications are changed and coded by theCompany. The Quality Assurance (QA) and Quality Control (QC) samples prepared by the Company represent about 12% of the totalprimary core samples. The three certified copper standards (both oxideand sulphide), acquired from Chilean company Instituto Nacional deTecnología Estandarización y Metrología Ltda. (“INTEM”), haveinternational standard certification. The certified standards are usedto evaluate the accuracy (approximation versus true value) of thelaboratory analysis. Blanks are used to evaluate the quality of thelaboratory preparation and identify possible contamination. Pulpduplicates are used to test analytical accuracy (repeatability). Nosecondary laboratory (referee lab) samples were completed in thisround of drilling; however, the next stage and subsequent stages ofdrilling will put in place laboratory replicate procedures. Once prepared, the core samples are bagged, tagged, andtransported to the laboratory by the project team. At the laboratoryreception, the samples and their identification codes are verified andaccepted once the physical inventory matches the assay request form. The pulps and rejects of crushed samples are collectedfrom the ALS-Patagonia laboratory in Copiapó every 3 months. Therejects are stocked in closed drums, identified with the correspondingbatches and sample ranges, while the pulps are stocked in boxes and inshelves inside a container separated for this purpose. Both arelocated in the same Company warehouse facilities in Copiapó. A visual review of the QA/QC results from the standardsand blanks inserted by the Company and the laboratory’s internalQA/QC information was completed by the Company and no significantissues were identified.
