VANCOUVER, Brit ish 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 c amp 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

o Including 4.30 m of 905.6 g/t silver

o 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

o Including 2.00 m of 977.2 g/t silver

o 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, t he 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.
