Brixton Metals Drills 22.15m of 4.44 g/t Gold Including 1.50m of 57.20 g/t Gold at the

Trapper Gold Target

VANCOUVER, British Columbia, October 15 , 2025 (GLOBE NEWSWIRE) - Brixton Metals

Corporation (TSX-V: BBB, OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce

additional drill results from the Trapper Gold Target from the 2025 season. A total of 6272m was

drilled at the Trapper Target from 30 holes this season. Assays are pending for the remaining 13

holes. The zone remains open for expansion.

Highlights

• Hole THN25-345 returned 22.15m of 4.44 g/t gold from 203.85m depth

o Including 1.50m of 57.20 g/t gold from 223.00m depth

• Hole THN25-342 returned 4.00m of 2.22 g/t gold from 210.00m depth

o Including 0.35m of 13.95 g/t gold from 212.35m depth

• Hole THN25-340 returned 30.85m of 1.47 g/t gold and 4.32 g/t silver from 61.65m depth

o Including 3.10m of 4.75 g/t gold and 16.01 g/t silver from 61.65m depth

o Including 6.00m of 4.24 g/t gold and 7.90 g/t silver from 80.00m depth

Chairman, CEO, Gary R. Thompson stated, “ We are thrilled to share another round of strong drill

results from the Trapper Gold Target, which continue to underscore the exceptional potential of this

emerging gold system. The intercept of 22.15 meters grading 4.44 g/t gold, including a high- grade

interval of 1.50 meters at 57.20 g/t gold, is particularly encouraging and speaks to the robust

mineralization we’re seeing at depth. These results, alongside other notable intercepts such as 30.85

meters of 1.47 g/t gold and 4.32 g/t silver, reinforce our confidence in the scale and continuity of the

Trapper zone. With assays still pending and the zone remaining open for expansion, we believe we

are only beginning to uncover the full extent of this exciting target.”

Discussion

Drill holes THN25-342 and THN25-345 were collared at the same location as THN25 -344 (see NR

07 Oct 2025. These holes were designed to infill and further delineate the trend of high- grade gold

mineralization previously intersected in hole THN22- 205 (Figure 1), which returned 64 metres

averaging 5.74 g/t gold. As demonstrated in this release, high- grade gold continues to be

encountered in this area.

Gold mineralization is hosted within Triassic lapilli tuff, which is intruded by a Cretaceous quartz

diorite and a feldspar porphyry dike of unknown age. The mineralization is associated with vein

assemblages containing pyrite, sphalerite, and galena (Figure 2). While all three lithologies host gold,

higher-grade intervals are preferentially located near the contacts between these units. Lower-grade

mineralization occurs between the reported intervals. Analytical results for silver and other elements

are pending from the laboratory.

Hole THN25-340 intersected gold and silver mineralization from shallow depths , associated with

feldspar porphyry dikes (Figure 3). This geological relationship, first recognized during the 2025

drilling campaign, has expanded the known footprint of gold mineralization eastward beyond

previously defined limits.

Quality Assurance & Quality Control

Quality assurance and quality control protocols for drill core sampling was developed by Brixton.

Core samples were mostly taken at 1.5m intervals. High-grade intervals were taken at 0.35 to 1.00m

intervals. Blank, duplicate (lab pulp) and certified reference materials were inserted at a combined

rate of 15%. Core samples were cut in half, bagged, zip- tied and sent directly to ALS Minerals

preparation facility in Whitehorse, Yukon or Langley, British Columbia depending on available lab

capacity. 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, whereas Ag, Pb, Cu and Zn

and 48 additional elements were analyzed using four acid digestion with an ICP -MS finish. Over

limits for gold were analyzed using fire assay and gravimetric finish. The standards, certified

reference materials, were acquired from CDN Resource Laboratories Ltd., of Langley, British

Columbia and the standards inserted varied depending on the type and abundance of mineralization

visually observed in the primary sample. Blank material used consisted of non-mineralized siliceous

landscaping rock. A copy of the QAQC protocols can be viewed at the Company’s website.
