CEO.CA Chairman's Briefing

VANCOUVER, British Columbia, Dec. 16, 2025 (GLOBE NEWSWIRE) -- Brixton Metals Corporation (TSX-V: BBB, OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce updated and complete assay results from the Trapper Gold Target at its wholly owned Thorn Project in northwestern British Columbia. This release includes multi-element results for all remaining holes from the 2025 campaign, as well as updated intervals for previously reported drill holes where only gold was disclosed. A total of 6272m was drilled at the Trapper Target from 30 holes this season. The Trapper gold zone remains open for expansion.

  • Including 3.00m of 28.83 g/t gold and 14.18 g/t silver from 223.00m depth
    
    
• Hole THN25-361 returned 23.50m of 3.33 g/t gold and 3.36 g/t silver from 92.00m depth
  
  
  • Including 0.50m of 112.00 g/t gold and 45.30 g/t silver from 112.00m depth

Chairman, CEO, Gary R. Thompson stated, “We are very pleased to deliver the multi-element assay results from the 2025 Trapper Gold Target campaign. These results not only confirm the continuity of high-grade gold mineralization but also demonstrate the presence of significant silver intervals across the target area. The updated data from previously reported drill holes, combined with new results from the remaining holes, further expand our understanding of the Trapper system and reinforce its potential for a large-scale mineralized system. We look forward to advancing exploration at Trapper and the broader Thorn Project as we continue to unlock value for our shareholders.”

Discussion – Trapper Gold Target

The 2025 campaign focused on expanding the known gold and silver mineralization within the central mineralized area and testing the continuity of mineralization, as observed in the 4 km-long, northwest-southeast-trending gold-in-soils anomaly (Figure 1). This strategic approach aimed to build on previous successes and further delineate the extent of high-grade gold zones at the Trapper Target (Figure 2).

The 2025 drill program successfully continued to demonstrate the significant gold and silver endowment of the Trapper Target. This year, a total of 6,272 meters were drilled across 30 holes, with the best intercepts represented by hole THN25-344, which returned 38.50 meters of 4.07 g/t gold and 6.71 g/t silver from 191.00 meters, and hole THN25-345, which returned 22.15 meters of 4.44 g/t gold and 3.45 g/t silver from 203.85 meters. These results reinforce the continuity and scale of high-grade mineralization at Trapper, supporting its potential for a large-scale mineralized system.

Gold mineralization at Trapper is structurally controlled, trending northwest-southeast and dipping moderately to the north in the main drilling area. Mineralization appears to favour the contact between the Cretaceous (85.2 ± 1.2 Ma) quartz diorite and Triassic lapilli tuffs, with broad gold intervals largely hosted along these faulted contacts. The gold is associated with silver and base metal veins containing pyrite, galena, sphalerite, and locally chalcopyrite and bornite.

The geochemical footprint for the Trapper Gold Target was expanded in 2021 to 4 km by 1.5 km, with a gold-in-soil signature strongly correlated to zinc and lead. Visible gold has been identified in both drill core and surface outcrops (Figure 3). Gold occurs in several environments: within base metal veins (sphalerite-galena-pyrite-chalcopyrite), quartz-stockwork, sulphosalt-pyrite veinlets, and, more rarely, disseminated in the diorite and feldspar porphyries.

Through a combination of oriented core drilling, surface mapping, geochemistry, and geophysics, Brixton aims to improve the predictability of gold-bearing zones and expand the mineralized footprint. The Trapper Target remains royalty-free, and ongoing work will focus on identifying new zones of gold-bearing mineralization under the footprint of the extensive geochemical anomaly. The zone remains open for expansion, and future exploration will target both known and newly interpreted structural corridors.

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 0.5m. 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 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. Overlimits 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.
