Brixton Metals Drills 906 g/t Silver over 4.3 m, including 1,329 g/t Silver over 1.8 m, all within 23.7 m of 206.6 g/t Silver at its Langis Project And 4.95 m of 493 g/t silver, including 1,798 g/t silver over 1.0 m

VANCOUVER, British Columbia, June 16, 2026 (GLOBE NEWSWIRE) — Brixton Metals Corporation (TSX-V: BBB, OTCQX: BBBXF) (the “Company” or “Brixton”) is pleased to announce results from its ongoing exploration at the wholly owned Langis Silver Project, located in the historic silver mining camp of Cobalt, Ontario, Canada. The 2026 drill campaign marks a significant milestone, targeting both infill and expansion of established high-grade silver zones. To date, a total of 18,678.05 meters across 90 drill holes has been completed in 2026.

Highlights

• Hole LM-26-342 intersected 23.70 m of 206.6 g/t silver from 109.80 m depth in the Shaft 6 South (S6-S) area
  • Including 4.30 m of 905.6 g/t silver
  • Including 1.80 m of 1,329 g/t silver

• Hole LM-26-355 intersected 4.95 m of 492.8 g/t silver from 146.10 m depth in the Shaft 6 Southeast (S6-SE) area
  • Including 2.00 m of 977.2 g/t silver
  • Including 1.00 m of 1,798 g/t silver

• Hole LM-26-348 returned 2.00 m of 624.0 g/t silver from 147.70 m depth in the Shaft 6 Southeast (S6-SE) area

Chairman, CEO, Gary R. Thompson stated, “We are delighted to report additional high-grade silver drill results from the Langis 2026 drill program. Furthermore, it is also promising to observe disseminated silver mineralization, as it’s generally associated with large-scale, bulk-tonnage potential. The second drill is now operational to meet our goal of 60,000 meters of drilling at Langis this year as we advance toward a maiden resource estimate. We were told by locals in the area that Brixton’s program is the largest drill campaign of any company in the camp.”

Discussion

Brixton’s 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). The results in this news release relate to both the S6‑S and S6‑SE zones (Table 1).

In the S6-S zone, drilling continues to return high-grade intercepts, headlined by hole LM‑26‑342, which intersected 1.80 m of 1,329 g/t silver within 23.70 m of 206.6 g/t silver. These results build on the ultra-high-grade silver mineralization previously reported in this year’s program (refer to the News Release, March 25, 2026).

Similarly, the latest results from hole LM-26-355 extend the high-grade silver mineralization previously reported in the S6-SE area to the north (refer to News Release, May 11, 2026). Hole LM-26-355 returned 4.95 m grading 492.8 g/t silver, including 1.00 m of 1,798 g/t silver. Unlike portions of S6-S that are impacted by historic mine workings, S6-SE has limited mine workings and no known historic stopes.

Mineralization in the Cobalt Camp and within the Langis property has mostly been observed in veins. However, as shown in Figures 1 and 2, the results presented in this news release also indicate disseminated silver mineralization in 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 the S6-S and S6-SE areas, silver mineralization is primarily hosted along the unconformity between the Keewatin Basalts and the Huronian Sediments. However, in the S6-SE area, mineralization is also observed within the Keewatin Basalts and the Nipissing Diabase (Figure 5). Follow-up drilling will focus on stepping out along strike to test continuity of the high-grade silver intervals and refine structural controls.

Table 1. Selected assay intervals from Langis Shaft 6 drill holes included in this news release.

All assay values are weighted averages. Reported intervals are drilling length, and the true width of the mineralized intervals has 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 for the project has been identified in the range of 1.0 million to 2.0 million tonnes grading 400 g/t to 800 g/t silver. 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 kilometres north of Toronto, Ontario, Canada, includes a former producing mine and excellent infrastructure, including all-season road access, power, rail connections, and a refiner. Silver mineralization is found as native silver and within steeply to moderately dipping veins, veinlets, disseminations, rosettes, and fracture infill, often associated with minerals such as calcite, hematite, pyrite, cobaltite, chalcopyrite, niccolite, and silver. 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 ore deposit model for this area is a continental-rift extensional depositional environment. Intermittently from 1908 to 1989, the Langis Mine produced 10.4 million ounces of silver at a head grade of 777.5 g/t silver (25 opt). Reported silver recoveries at Langis were 88% to 98%. Over 10 km of underground workings were developed by previous operators; however, shafts and openings have been capped and sealed. Historically, silver mines in the Cobalt Camp have collectively produced over 445 million ounces of silver.

Quality Assurance & Quality Control

Quality assurance and quality control protocols for drill core sampling were developed by Brixton. Core samples were mostly taken at 1.5 m intervals. High-grade intervals were taken at 0.50 m to 1.00 m 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 9001:2008 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.
