Brixton Metals Corporation (TSX-V: BBB) (OTCQX: BBBXF) is pleased to announce the third batch of 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 8,282 metres across 43 drill holes has been completed in 2026 (Figure 8). This includes 9 holes previously reported (refer to News Release, March 10, 2026), 5 holes previously released (refer to News Release, March 18, 2026) and 4 holes for 649.80m reported herein.

Highlights

• Hole LM-26-290 intersected ultra high-grade silver returning 82,334 g/t silver or 8.23% or 2,647 troy ounces per tonne over 0.5m from 115.25m depth
  • Within 11.35m grading 4,560 g/t silver from 112.0m depth.

• Hole LM‑26‑292 intersected 18.6 m of 155.4 g/t silver from 106.4m depth
  • Including 1.0 m of 771.5 g/t silver from 111 .5m and
  • Including 1.2 m of 1,166 g/t silver from 116.8m
• Hole LM‑26‑291 returned 8.6 m of 96.7 g/t silver from 158.0m depth
  • Including 0.5m of 1,245 g/t silver from 162.2m

Chairman, CEO, Gary R. Thompson stated, “We are excited to report the third batch of drill results from the Langis 2026 drill program. These results are extraordinary and are among the most significant silver drilled intercepts known to the Company globally. Hole LM‑26‑290 has delivered an exceptional result, highlighted by 82,334 g/t silver from a 0.50m core length sample containing abundant native‑silver. This represents the highest‑grade single sample ever reported by the Company and, to our knowledge, one of the highest silver grades eve r reported globally. Importantly, this result demonstrates that despite historic mining at Langis, the mineral system continues to host outstanding high‑grade silver potential. These results clearly indicate that mineralization remains to be discovered and reinforce Langis as a truly unique primary silver project.”

Discussion

The initial drill holes of the 2026 program were designed to evaluate silver mineralization south of the Shaft 6 area (Figures 3 and 4). Previous exploration campaigns in this area identified silver mineralization predominantly hosted within vertical, dilatant zones and shear‑related veins, typically occurring as centimetre‑sc ale native silver veinlets, disseminations, rosettes and fracture infill. Several holes reported herein successfully intercepted silver mineralization (Table 1).

Hole LM‑26‑290 intersected two veins of massive native silver associated with cobalt‑ and nickel‑bearing minerals. These veins measured approximately 25 cm and 40 cm in width and returned 2,408 g/t silver and 82,334 g/t silver, respectively, over individual 0.5 m sample intervals (Figures 7). The 82,334 g/t silver result represents the highest‑grade silver assay reported from the Langis Project to date. Silver within these veins occurs predominantly as native silver closely associated with cobalt and nickel‑rich minerals (Figure 1). In the wider vein, native silver is concentrated within cobalt‑rich spheroidal minerals, as observed in micro‑XRF imagery (Figure 2). This style of mineralization demonstrates that the Langis system can host discrete veins of ultra-high-grade silver minera lization.

Drilling continues in the Langis Shaft 6 area, with the ongoing program focused on expanding and infilling known silver mineralization and further evaluating the controls on high‑grade vein development.

This cross-section displ ays only drill holes oriented subparallel to the section (90° ± 4° azimuth); drillholes with other orientations are omitted. Lithological contacts are interpretive and based on prior drilling. Historic drillhole assays are projected to a maximum of 20m from the section. Drilling of hole LM-26-290 was terminated upon intersecting a historic mine working at 123.35m depth. Assays for LM-26-289 are pending.

About the Langis Project

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 fra cture 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 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.

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 9001:2008 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 Re source 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.
