Including 6m of 6.17 g/t Gold, 221 g/t silver, 1.4% Copper and 0.27% Antimony from 63m depth

Brixton Metals Corporation (TSX-V: BBB) (OTCQB: BBBXF) is pleased to announce its second batch of drill results of the 2025 season from its wholly owned Thorn Project located in NW British Columbia, Canada. The Thorn Project is an underexplored copper-gold porphyry district with several large-scale exploration target areas identified.

Highlights

• Shallow drilling was successful in extending the Glenfiddich Zone mineralization 105m northeast and remains open along strike and down dip
• Hole THN25-322 returned 16m of 3.40 g/t gold, 96.08 g/t silver, 0.59% copper, 0.12% antimony from 61m depth
  • Including 9.55m of 5.22 g/t gold, 157.68 g/t silver, 0.97% copper, 0.19% antimony
  • Including 6.00m of 6.17 g/t gold, 221.20 g/t silver, 1.40% copper and 0.27% antimony
  • Including 3.00m of 8.16 g/t gold, 159.66 g/t silver, 0.73% copper, 0.17% antimony and 1.05% zinc from 66m depth

Chairman, CEO, Gary R. Thompson stated, “These 5 reported holes for a total of 600m at the Glenfiddich Zone were following up on surface rock grabs that returned 20 g/t gold and previous drilling. We believe that these feeder structures are related to the Camp Creek porphyry at depth. Based on these new high-grade results and the fact that the Glenfiddich Zone remains open, more shallow drilling in this area is warranted to define the limits of this gold-copper-silver-antimony mineralization.”

Discussion

The objective was to expand the northeast trending mineralization identified in previous drilling at the Glenfiddich Zone and to follow up on high gold values found in surface rock grab samples of quartz breccia material.

Holes THN25-320, THN25-321 and THN25-322 were collared from the same pad and drilled at an azimuth of 140 degrees with dips of -60, -75 and -80 degrees and to depths of 109m, 136m and 172m, respectively. The collar was located 51m to the northeast from hole THN11-49 (Figure 2). Hole THN11-49 intersected 24.04m of 0.89 g/t gold, 12.4 g/t silver, and 0.6% copper, including 5.04m of 2.35 g/t gold, 32.8 g/t silver and 0.15% copper.

Holes THN25-323, and THN25-324 were drilled from the same pad and were collared at an azimuth of 140 degrees on the same pad with dips: -50, and -70 to depths of 67m and 116m respectively and the collar was located 56m northeast from hole collar THN25-322.

These 5 holes extended the near surface Glenfiddich Zone by 105m to the northeast. Mineralization such as quartz-breccia-pyrite-sulphosalt-sphalerite-galena with trace bornite-covellite is hosted within a pervasively sericite-pyrite altered diorite porphyry Z unit.

The Glenfiddich Zone of mineralization now has a new strike length of 380m and has been drilled to a vertical depth of 30-80m. The zone remains open along strike and at depth with a strike estimate of 700m to 1000m and depth potential of 300-500m and with widths up to 50m.

Further drilling is planned before the end of the 2025 season on this target.

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 0.4 to 1m 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.
