VANCOUVER, British Columbia, June 01, 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, 60,000m of drilling, the largest in the history of the project, focusing on both infill and expansion of high-grade silver zones. To date, a total of 14,760.65 meters across 72 drill holes has been completed in 2026.

Highlights

Hole LM-26-341 south of Shaft 6 intercepted:

27.7 m of 166.45 g/t silver from 99.3 meters
- Including 2.3 m of 1,811 g/t silver from 107.2 meters
  - Including 0.5 m of 5,580 g/t silver from 108.5 meters and
2.0 m of 700 g/t silver from 149.0 meters

Hole LM-26-338 south of Shaft 6 intercepted:

17.5 m of 170.8 g/t silver from 105.5 meters
- Including 1.0 m of 1,150 g/t silver from 115.0 meters

These recent results demonstrate continuity of mineralized zones between previously reported ultra-high-grade silver intervals, including those reported in holes 289 and 305 (refer to New Releases, May 11, 2026 and March 18, 2026).

Chairman, CEO, Gary R. Thompson stated, “Langis continues to deliver kilogram per tonne plus silver results and meaningful grades over substantial widths. The second drill is now operating at Langis to meet our goal of 60,000 m this year as we advance toward a maiden mineral resource estimate.”

Discussion

Drill holes reported herein (Table 1, Figure 3) were designed to evaluate the continuity of mineralization between the ultra-high-grade silver intercepts previously reported from holes LM-26-289 and LM-26-305 in the Shaft 6 South area (Figure 5). The interval of 2.3 m grading 1,811 g/t silver within a broader interval of 27.7 m grading 166.45 g/t silver on hole LM-26-341 confirms this continuity, albeit with variable grades that are consistent with the vein-hosted nature of mineralization at Langis. As observed in Figures 1 and 2, silver mineralization in hole LM-26-341 is associated with sulphide + carbonate veins and visible centimetre-scale native silver, ± cobaltite. Collectively, to date, the results from the 2026 field campaign demonstrate that continuous high-grade silver mineralization persists within areas of historical mining (Figure 5).

About the Langis Project

The wholly owned Langis Silver Project located approximately 500 kilometers 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. Reported silver recoveries at Langis were 88% to 98%. Over 10km 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.

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 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.

Quality Assurance & Quality Control

Quality assurance and quality control protocols for drill core sampling were developed by Brixton. Core samples were mostly taken at 2m 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 9001:2008 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.
