VANCOUVER, British Columbia, July 21, 2026 (ZM NEWSWIRE) — Brixton Metals Corporation (TSX-V: BBB, OTCQX: BBBXF) (the “Company” or “Brixton”) is pleased to report the discovery of ultra-high-grade silver in a new brownfields area called the Shaft 6 Southeast area (S6-SE) at its wholly owned Langis Silver Project, located in the historic silver mining camp of Cobalt, Ontario, Canada. These results come from the Company’s 2026 drill campaign, its largest drill program to date, which is targeting both infill and expansion of established high-grade silver zones, with a total of 24,016.90m completed across 105 drill holes so far this year. In parallel, the Company is progressing toward a maiden Mineral Resource Estimate (MRE) on the historic tailings; 261.35m of drilling have been completed, and samples have been shipped to the laboratory for assaying.

Highlights

• In the S6-SE area, hole LM-26-377 yielded 20.00m of 5,015 g/t silver from 165.00m depth
  • Including 14.00m of 7,150 g/t silver
  • Including 1.15m of 74,137 g/t silver
  • Including 0.65m of 89,125 g/t silver

• In the S6-SE area, hole LM-26-353 returned 13.00m of 287.8 g/t silver from 144.00m depth
  • Including 2.15m of 1,634 g/t silver
  • Including 0.55m of 4,320 g/t silver
• In the S6-SE area, hole LM-26-352 intersected 7.00m of 275.0 g/t silver from 148.00m depth
  • Including 0.50m of 2,620 g/t silver

Chairman and CEO, Gary R. Thompson stated, “We are super excited to have drilled more ultra-high-grade silver at Langis, especially in the Shaft 6 Southeast (S6-SE) area where no underground workings exist, effectively a new brownfields discovery. As far as we can find in publicly available data, hole 377 represents one of the highest reported silver intercepts globally. Hole 377 is located approximately 140m east of the previously reported hole 290 (Shaft 6 South), see Figure 1 below, which yielded 11.35m grading 4,560 g/t silver. Further drilling is ongoing in the S6-SE area, including between the two ultra-high-grade intercepts in holes 377 and 290 and what appears to be a south-east mineralized trend. We have a lot more holes that we plan to drill at Langis.”

Discussion

Hole LM-26-377, drilled in the Shaft 6 Southeast (S6-SE) area, returned 0.65m grading 89,125 g/t silver within 20.00m grading 5,015 g/t silver and is located approximately 140m east of previously reported hole LM-26-290, which returned 0.50m of 82,334 g/t silver within 11.35m grading 4,560 g/t silver (Figure 1). The S6-SE area has no known historic underground workings and has never been mined; these results support the presence of ultra-high-grade silver in this new discovery area. Silver mineralization at S6-SE has now been outlined over at least 100m along strike and remains open along strike, down-plunge, and laterally. Brixton’s 2026 exploration around the historic Shaft 6 area at Langis has outlined at least two zones of silver mineralization, Shaft 6 South (S6-S) and Shaft 6 Southeast (S6-SE), both of which have now returned ultra-high-grade silver (Figure 1). This news release presents results from both areas, as well as from Shaft 6 North (S6-N) (Figure 7).

Earlier drilling in the S6-SE area returned encouraging results, outlining continuous silver mineralization across several holes (refer to News Release, May 11, 2026), with silver occurring in both vein and disseminated styles. Hole LM-26-377 now confirms the potential for ultra-high-grade silver in this area, returning 0.65m grading 89,125 g/t silver within 20.00m grading 5,015 g/t silver (Table 1). These two ultra-high-grade results are separated by approximately 140m. Strong grades in S6-SE are not limited to a single hole; hole LM-26-353 intersected 0.55m of 4,320 g/t silver within 13.00m of 287.8 g/t silver (Table 2).

The ultra-high-grade intercept in hole 377 establishes clear similarities with the S6-S area, where ultra-high-grade silver mineralization was reported earlier in this year’s program (refer to News Release, March 25, 2026). A key difference, however, is mining history: unlike portions of S6-S that are impacted by historic mine workings, S6-SE has limited workings and no known historic stopes.

The two areas also share the same mineralization styles. In the Cobalt Camp and within the Langis property, silver has mostly been observed in veins; however, disseminated silver mineralization has also been observed in both the S6-S and S6-SE areas. The combination of high- and ultra-high-grade silver veins with disseminated silver is encouraging for the exploration program, as it extends mineralization beyond the veins. In both areas, silver mineralization is primarily hosted along the unconformity between the Keewatin Basalts and the Huronian Sediments, and is also observed within the Keewatin Basalts and the Nipissing Diabase (Figure 1).

In parallel with extending the known mineralized zones, Brixton is actively drilling other prospective targets. Although results from the Shaft 6 North area are not economically mineralized, several intercepts with anomalous silver show that silver mineralization continues north of the historic Shaft 6 (Table 3).

Follow-up drilling is advancing on three fronts. In the S6-S and S6-SE zones, drilling is stepping out along strike to test the continuity of the high-grade silver intervals and refine structural controls, and will also target a potential connection between the two zones. In parallel, exploratory drilling continues to test prospective targets across the property to outline new zones of mineralization. Finally, 261.35m of drilling have been completed in the Langis tailings areas and samples have been shipped to the laboratory for assaying and metallurgical testing and these results shall be released as they become available.

Table 1. Selected assay intervals from drill holes in the Shaft 6 Southeast (S6-SE) zone reported in this news release.

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 shown as “No significant intercepts.” Higher-grade “including” intervals reflect geological interpretation.

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%. Over 10 km of underground workings were developed by previous operators; 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 actual silver production from the camp is significantly higher than the reported numbers.

Quality Assurance & Quality Control

Quality assurance and quality control protocols for drill core sampling were developed by Brixton. Core samples were mostly taken at 1.5m intervals. High-grade intervals were taken at 0.50m to 1.00m intervals. Blank, duplicate (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. Overlimits for silver 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.
