Vancouver, British Columbia – TheNewswire - October 5, 2026 – Fitzroy Minerals Inc. (TSXV: FTZ, OTCQX: FTZFF, FSE: C3Y) (“Fitzroy” or the “Company”) is pleased to report further high-grade copper from drill core results and provide an update on development activities at its advanced Buen Retiro Copper Project, Copiapó, Chile (“Buen Retiro” or the “Project”).

Fitzroy has completed 22,697 metres of diamond drilling and 2,780 metres of RC drilling at Buen Retiro in 2026 as of September 30 and drilling continues with two diamond drill (“DD”) rigs and one reverse circulation (“RC”) drill rig. The current program is focused on defining Measured and Indicated Resources at Tenorita and Inferred Resources at Nativo, Ortúzar, and the extensions of Tenorita. This news release reports results from diamond drill holes BRT-DDH101 to BRT-DDH128 (Table 1).

In parallel with exploration, Fitzroy continues to advance multiple workstreams supporting a potential near-term heap-leach development at Buen Retiro. These include geotechnical studies, sterilization drilling, environmental baseline studies, metallurgy, mineral processing, and engineering. As exploration and technical work have progressed, the potential scale of the Project has increased and Fitzroy has expanded both its environmental baseline studies and the scope of the proposed Buen Retiro Heap Leach development program.

In Q4 2026, the statement of environmental impact (“DIA”), the application for an environmental permit will be submitted and a maiden Mineral Resource Estimate (“MRE”) and a Preliminary Economic Assessment (“PEA”) will be published. The PEA will incorporate Inferred Resources across the wider Project area. In Q2 2027, Fitzroy will publish a Pre-Feasibility Study (“PFS”) with an updated MRE and maiden Mineral Reserve Statement based on the central portion of Tenorita.  

Drilling Highlights from the Nativo Area, Buen Retiro:

• BRT-DDH110: 30.5 m @ 2.48% Cu from surface to end of hole and ended in mineralization. 

• BRT-DDH121: 18 m @ 2.50% Cu from 163 m, including 10 m @ 4.00% Cu from 163 metres. 

• BRT-DDH117: 166 m @ 0.37% Cu from 81 m, including 105 m @ 0.52% Cu from 92 m and 30 m @ 1.23% Cu from 144 metres. 

• BRT-DDH115: 43 m @ 0.83% Cu from 115 m, including 32 m @ 0.98% Cu from 121 metres. 

Project Highlights:

• DIA and environmental permit application to be submitted in Q4 2026.  

• Maiden MRE and a PEA that will encompass Tenorita, Nativo, and Ortuzar areas to be published in Q4 2026. 

• PFS planned for delivery in Q2 2027. 

Merlin Marr-Johnson, President and CEO of Fitzroy, commented: “Buen Retiro continues to improve as our understanding of the scale and potential of the Project grows. In just 24 months of fieldwork, we have defined a remarkably continuous body of leachable copper mineralization and we are advancing multiple avenues of study in parallel.

Thanks to the notable infrastructure advantages of the Project, we are confident that Buen Retiro has the potential to deliver the kind of low-capital-intensity, near-term copper production that the market urgently needs. At a time when many new copper projects require billions of dollars and a decade or more to reach production, Buen Retiro offers a very different proposition: a simple heap leach, in an established mining district, with the potential to produce copper cathode quickly and efficiently.

Significantly, the opportunity extends well beyond Tenorita. Recent drilling at Nativo continues to demonstrate the scale and quality of the broader mineralized system, including 30.5 metres at 2.48% Cu from surface in BRT-DDH110 and 166 metres at 0.37% Cu in BRT-DDH117, including 30 metres at 1.23% Cu.

We expect to demonstrate the significance of this broader opportunity through two important milestones in Q4: a maiden Mineral Resource Estimate and a Preliminary Economic Assessment. Together, these studies should begin to quantify what we believe makes Buen Retiro unusual: leachable copper mineralization, excellent infrastructure, low capital intensity and the potential for a rapid pathway to production.”

Drilling Overview

As of September 30, Fitzroy has completed 168 diamond drill holes for a total of 22,697 metres since the start of February 2026 (Figure 1). Drilling with three drill rigs at the Project is ongoing. Currently one DD rig is in the Ortúzar Area while the other DD rig and the RC rig are testing regional exploration targets. Fitzroy is likely to complete a further 4,000 m of drilling in 2026.

Geology Update

As drilling has progressed at Buen Retiro, three distinct geological domains have been identified, each of which has distinct geological and geostatistical characteristics. Copper mineralization at Tenorita strikes north-northwest and dips steeply to the east. Tenorita is remarkably consistent along strike and remains open to the southeast.

Mineralization at Nativo strikes north-south and is subvertical. Nativo merges with Tenorita to the south and continues north into the middle of the historical Manto Negro open pit. Copper mineralization at both Tenorita and Nativo is centred on ferric breccias, with a width of approximately 70 metres. Where the two trends merge, a third ferric breccia is present, and a wide zone of shallow copper mineralization is present. Most of the mineralization intersected in these two areas has been copper oxide and mixed (copper oxides and secondary, leachable sulphides), down to depths of 120-150 metres.

Ortúzar is geologically distinct from Tenorita and Nativo and displays greater variability and complexity. Ortúzar extends southwards as far as the middle of the historical Manto Negro open pit. The dominant mineralization at Ortúzar is disseminated ‘manto-style’ controlled by lithology, dipping at approximately 30o to the northwest. The mantos have a relatively shallow depth of oxidation (60-80 metres) and chalcopyrite becomes the dominant copper mineral down-dip. The north-south structure that characterizes the Nativo area appears to continue into the Ortúzar area, creating an oxidised portion of Ortúzar to the north and east of the historical Manto Negro open pit. Additionally, metasomatic copper mineralization (chalcopyrite) at the contact of dioritic intrusions has been identified.

Drilling Results and Core Assays

Of the 28 drill holes from BRT-DDH101 to BRT-DDH128, BRT-DDH101 is the only geotechnical drill hole and the others are exploration drill holes (Table 1).

Drilling continues to intersect copper mineralization, including high-grade zones beneath the historical Manto Negro open pit. BRT-DDH110 intersected 30.5 metres at 2.48% Cu from surface to the end of the hole and ended in mineralization; the hole ended prematurely due to technical issues.

Six drill holes (BRT-DDH 102, 104, 105, 107, 114, and 120) were completed in the Tenorita area. Southern infill hole BRT-DDH107 intersected 63 metres at 0.56% Cu from 63 metres, while BRT-DDH104, drilled at the northern end of the trend near the historical waste dump, intersected 80 metres at 0.33% Cu from 16 metres.

Eighteen drill holes (BRT-DDH 101, 103, 106, 108-113, 115, 117-118, 121-122, 124-126, and 128) were completed in the Nativo area. The best results were BRT-DDH110 (Table 1; Figure 2) and BRT-DDH117 which intersected 166 metres at 0.37% Cu from 81 metres, including 105 metres at 0.52% Cu from 92 metres and 30 metres at 1.23% Cu from 144 metres (Table 1; Figure 3). All intersections were made in oxide and mixed zones, hosting leachable mineralization.

Four drill holes (BRT-DDH 116, 119, 123, and 127) were completed in the Ortúzar area. The mineralization below 75 metres down-hole in these holes consisted predominantly of chalcopyrite. The best result was BRT-DDH127, which intersected 56 metres of oxides at 0.33% Cu from 8 metres, including 4 metres at 1.19% Cu from 33 metres before intersecting a number of sulphide intervals from depths of 113 metres to 295 metres (Table 1).

Buen Retiro Core Sampling Procedures, Laboratory and QA/QC

Buen Retiro HQ drill core, in labelled and secured wooden core trays, is picked up from the drilling site by Company personnel and transported by truck from the drill rig to the core processing facility in Copiapó. Core lengths are checked, after which geotechnical logging is performed.

HQ and NQ drill core is cut in half using a diamond saw, with one half submitted for analysis and the remaining half retained in the original core trays at the rented core storage warehouse in Cuesta Cardones, south of Copiapó.

Fitzroy is using two laboratories for its samples. Samples from the Tenorita area are sent to the ALS-Patagonia laboratory in Copiapó for sample preparation and the pulps are sent to ALS-Peru for assay. Samples from the Nativo and Tenorita areas are sent to the SGS laboratory in Copiapó for sample preparation and analysis.

A silica blank is inserted every 20 samples (approximately every 20 m); a blank is always inserted immediately after a section that contains native copper. Pulp duplicates are randomly selected in proportion to the number of samples from each drill hole and inserted into the sample stream along with high-, medium-, and low-grade copper standards. Sample identifications are changed and coded by the Company. At the same time, a coarse duplicate is prepared and sent to a secondary laboratory, (either SGS or ALS depending on which is the primary laboratory), for analysis using the same analytical method.

The Quality Assurance (QA) and Quality Control (QC) samples prepared by the Company represent about 12% of the total primary core samples. The three certified copper standards (both oxide and sulphide), acquired from Chilean company Instituto Nacional de Tecnología Estandarización y Metrología Ltda. (“INTEM”), have international standard certification. Certified reference materials are used to monitor analytical accuracy. Blanks are used to evaluate the quality of the laboratory preparation and identify possible contamination. Pulp and coarse-reject duplicates are used to monitor analytical precision. A secondary laboratory (either SGS or ALS depending on which is the primary laboratory) is used as a referee laboratory, as a check on replicating lab procedures.

Once prepared, the core samples are bagged, tagged, and transported to the laboratory by the project team. At the laboratory reception, the samples and their identification codes are verified and accepted once the physical inventory matches the assay request form.

The pulps and rejects of crushed samples are collected from the ALS-Patagonia laboratory in Copiapó, or from the SGS laboratory in Santiago every three months. The rejects are stocked in closed drums, identified with the corresponding batches and sample ranges, while the pulps are stocked in boxes and on shelves inside a container separated for this purpose. Rejects and pulps are located in the same Company warehouse facilities in Copiapó.

A visual review of the QA/QC results from the standards and blanks inserted by the Company and the laboratory’s internal QA/QC information was completed by the Company and no significant issues were identified.

The Company and Qualified Person are independent of the assay laboratories disclosed in this news release.
