Brixton Metals Corporation (TSX-V: BBB, OTCQB: BBBXF) is pleased to announce its first 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. Brixton is operating with one diamond drill and is gearing up to add a second drill before the end of July.

Highlights

• Shallow drilling was targeting northeast trending gold bearing feeder structures related to the Camp Creek Cu-Au-Ag-Mo porphyry system:
  • Hole THN25-318 cut 1.5m of 9.5 g/t gold, 13.8% copper, 771.5 g/t silver, 7.6% lead, 609.50 g/t tellurium, 7.1% zinc from 165.5m depth
  • Including 0.75m of 10.25 g/t gold, 13.50% copper, 825 g/t silver, >1% antimony, 419 g/t tellurium, 15.15% lead, 14.00% zinc
  • Including 0.75m of 8.80 g/t gold, 14.15 % copper, 718 g/t silver, 1.38% antimony, 800 g/t tellurium
  • Directly above and excluding the high-grade zone is a 19.5m interval that returned 0.43 g/t gold, 37.97 g/t silver, 0.55% copper from 146m depth (146-165.5m)

Chairman, CEO, Gary R. Thompson stated, “We are excited to have captured a gold rich polymetallic interval in hole 318. Our strategy this year at the Camp Creek Target was to drill for near surface gold mineralization along these northeast trending feeder structures, which has seen limited drilling since the deep porphyry discovery in Camp Creek. We believe that these feeder structures are related to the Camp Creek porphyry. While the drill has been moved to the Trapper Gold Target, more shallow drilling at the Camp Creek Target area is warranted.”

HQ size core samples were cut in half and sampled predominantly at 1.5m intervals with the exception of the high-grade that was sampled at 0.75m intervals for all reported holes in this release. Assay values are weighted averages. Reported intervals are drilling length and the true width of the mineralized intervals has not yet been determined.

Discussion

Holes THN25-315 and THN25-316 were drilled at an azimuth of 325 degrees and dip of -50 and -77 degrees, respectively, and the collar was located 123m to the southeast from hole THN24-307 (Figure 2). Hole THN24-307 intercepted a gold dominant zone of high-sulphidation mineralization (see news release, December 9, 2024).

Holes THN25-317, THN25-318 and THN25-319 were drilled at an azimuth of 295 degrees on the same pad with dips: -45, -65, -75, respectively, and the collar was located 202m northeast from hole THN25-315.

Quartz-sericite-pyrite alteration was pervasive in all of these reported holes within the diorite porphyry Z unit. Disseminated pyrite of 1-3% was identified in the groundmass and locally increases up to 6% with common veinlets of pyrite-sulphosalts up to 20cm and in the case of hole THN25-318 massive sulphide up to 1.5m wide. Localized zones of chlorite and potassic alteration was observed.

This newly identified northeast structural trend, the “Northside vein”, which is parallel to the Talisker zone (Figure 2), appears to have a minimum strike of 780m based on six collars-drill sites. Further drilling is required to define the limits of this new trend and to expand on the exceptional high-grade mineralization identified in hole THN25-318.

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 0.75m intervals. Blank, duplicate (lab pulp) and certified reference materials were inserted into the sample stream for at least every 20 drill core samples. 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.
