And 6.45 m of 667 g/t Silver, Including 3.19 m of 1,339 g/t Silver In Hole 412

And 9.00 m of 222 g/t Silver, Including 0.50 m of 1,605 g/t Silver In Hole 442

Brixton Metals Corporation (TSX-V: BBB) (OTCQX: BBBXF) is pleased to report silver results from 28 holes at its wholly owned Langis Silver Project, located in the historic silver mining camp of Cobalt, Ontario, Canada. These results come from several different areas of the project that the Company is actively exploring. So far in 2026, the Company has completed 39,937.55 m across 182 drill holes. The Company has added a third drill rig to the Langis program, targeting 9,000 metres per month. This accelerated drilling rate is needed to meet our near-term objective of establishing a maiden Mineral Resource Estimate at Langis.

Discussion

Shaft 6 South East (S6-SE)

New results from this recently discovered brownfield area (Table 1), with no mining works (see news release dated July 21, 2026), show mineralization extending to the south. Drilling to test the extension of this zone returned strong results in holes LM-26-421, LM-26-427 and LM-26-449, with hole LM-26-449 returning the main intercept of 23.50 m of 348.11 g/t silver from 203.00 m depth.

As observed in Figures 2 and 3, disseminated native silver accompanies the vein-hosted mineralization and native silver veinlets. Brixton interprets this as an upside to the traditional vein-focused exploration approach at Langis, as the disseminated silver appears to create broad shoulders of mineralization flanking the veins, which could significantly widen the mineralized envelopes.

Table 1. Selected assay intervals from drill holes in the Shaft 6 South East (S6-SE) zone.

No significant intercepts were returned from hole LM-26-425.
Note for all assay tables: All assay values are weighted averages. Reported intervals are drilling lengths, and the true widths of the mineralized intervals have not yet been determined. Reported intervals are length-weighted composites calculated at a 5 g/t Ag cut-off over contiguous samples, with limited internal dilution. A hole is reported as a significant intercept only where it contains a sub-interval exceeding 50 g/t Ag; otherwise, it is reported as no significant intercepts. Higher-grade “including” intervals reflect geological interpretation.

Shaft 6 East (S6-E)

Drilling in the Shaft 6 East (S6-E) area (Table 2) tested mineralization in this zone, with good results in holes LM-26-429 and LM-26-433; the latter returned 10.50 m of 85.74 g/t silver from 192.50 m depth. However, the Company has not yet established significant continuity of mineralization. While the mineralized intercepts warrant further exploration, the mineralization in S6-E is being intersected at greater depths, and the Company has therefore decided to move to shallower zones.

Table 2. Selected assay intervals from drill holes in the Shaft 6 East (S6-E) zone.

No significant intercepts were returned from holes LM-26-437, LM-26-439 and LM-26-445.

Shaft 6 (S6)

In the Shaft 6 (S6) area (Table 3), drilling also continues to return good results around historic stopes, including holes LM-26-426, LM-26-428 and LM-26-442, with hole LM-26-442 returning the main intercept of 9.00 m of 221.91 g/t silver from 119.00 m depth.

Table 3. Selected assay intervals from drill holes in the Shaft 6 (S6) zone.

No significant intercepts were returned from holes LM-26-430, LM-26-436, LM-26-438, LM-26-440, LM-26-444 and LM-26-446.

Shaft 6 West (S6-W)

Drilling in the Shaft 6 West (S6-W) area (Table 4) continues to confirm the good initial results reported in the news release dated September 2, 2026, with mineralization around the historic mine workings. Good results were returned in holes LM-26-412, LM-26-417, LM-26-420A and LM-26-424, with hole LM-26-412 returning the main intercept of 6.45 m of 666.95 g/t silver from 124.65 m depth.

Brixton is looking to potentially expand this mineralization at S6-W to demonstrate continuity, as the Company has been doing in the Shaft 6 South East (S6-SE) area.

No significant intercepts were returned from hole LM-26-422.

Shaded areas show where individual drill core samples from previous drilling returned ≥30 g/t Ag, projected to surface (Figures 4 & 6) or onto the section plane (Figure 5). They are a visual aid only. They are not a geological model, a mineral resource or a mineral reserve, and they do not imply continuity of mineralization between drill holes.

Drill holes between 5,270,680 m N and 5,270,910 m N are projected onto a vertical west–east plane along 5,270,795 m N. Only the holes in this release are labelled and drawn with their lithology: Huronian conglomerate, Keewatin mafic volcanics and Nipissing diabase. Composites are plotted at the interval mid-point and coloured by silver grade. Shaded areas show samples ≥30 g/t Ag from previous drilling within the same window. No vertical exaggeration. Projection: points up to 115 m from the section line appear together, so intercepts that look close on the section may be separated in three dimensions. Composites and shading: same definitions and limitations as Figure 4. Reported intercepts are core lengths; true widths are not yet known.

About the Langis Project

An Exploration Target of 1.0 to 2.0 million tonnes grading 400 to 800 g/t silver has been conceptualized for the project. Note: The potential quantity and grade of the Exploration Target are conceptual. Insufficient exploration has been completed to define a mineral resource, and there is no certainty that further exploration will result in the target being delineated as a mineral resource.

The wholly owned Langis Silver Project, located approximately 500 km north of Toronto, Ontario, Canada, includes a former producing mine and benefits from excellent infrastructure, including all-season road access, power, rail connections, and a refiner. Silver mineralization occurs as native silver and in steeply to moderately dipping veins, veinlets, disseminations, rosettes, and fracture infill, often associated with minerals such as calcite, hematite, pyrite, cobaltite, chalcopyrite, niccolite, and gold. Mineralization is hosted across three principal rock types: Archean Keewatin volcanic and metasedimentary rocks, Proterozoic Coleman Member sedimentary rocks of the Huronian Supergroup, and Proterozoic Nipissing diabase. The geological deposit model for the area is a continental-rift extensional depositional environment. The Langis Mine produced 10.4 million ounces of silver intermittently between 1908 and 1989 at a head grade of 20 to 25 opt, with reported recoveries of 88% to 98%. Previous operators developed over 10 km of underground workings; however, shafts and openings have been capped and sealed. Historically, reported silver mines in the Cobalt Camp have collectively produced over 445 million ounces of silver. We also understand, through personal communication with mine workers in the camp, that ultra-high-grade native silver collector pieces did not make it through the mills, suggesting that the camp’s actual silver production is significantly higher than the reported numbers. The historic production figures referenced above are sourced from third-party records and personal communications, have not been verified by Brixton or by the Qualified Person, and should not be relied upon.

Quality Assurance & Quality Control

Quality assurance and quality control protocols for drill core sampling were developed by Brixton. Core samples were mostly taken at 2.0 m intervals. High-grade intervals were taken at 0.50 m to 1.00 m intervals. Blanks, duplicates (lab pulp), and certified reference materials were inserted at a combined rate of up to 15%. Core samples were cut in half, bagged, zip-tied, and sent directly to the ALS Minerals preparation facility in Sudbury, Ontario. ALS Minerals Laboratories is registered to ISO 9001:2015 and ISO 17025 accreditations for laboratory procedures. Samples were analyzed at ALS Laboratory Facilities in North Vancouver, British Columbia, for gold by fire assay with an atomic absorption finish. Ag, Pb, Cu, and Zn, as well as 48 additional elements, were analyzed using a four-acid digestion with an ICP-MS finish. Overlimit silver samples were analyzed using fire assay and gravimetric finish, and/or fire assay and gravimetric finish on concentrates. The certified reference materials were acquired from CDN Resource Laboratories Ltd. of Langley, British Columbia, and the standards inserted varied with the type and abundance of mineralization observed in the primary sample. Blank material used consisted of non-mineralized siliceous landscaping rock. A copy of the QAQC protocols is available on the Company’s website.

Corporate Update

On October 1, 2026, Eldorado Gold Corporation gave notice of termination to Brixton for its Earn-in Agreement for the Atlin Goldfields Project.
