Including 8.77m of 2.52 g/t Gold, 120.87 g/t Silver, 1.22% Copper and 1481 g/t Antimony

Brixton Metals Corporation (TSX-V: BBB) (OTCQB: BBBXF) is pleased to announce further drill results from its near surface program at Camp Creek area. These 2 holes are the balance of early 2025 season drilling in the Camp Creek area for a total of 2165m over 12 holes. Drilling continues at the Trapper Gold Target with 3408m over 15 holes (assays pending) and 1025m over 2 holes at the Catalyst Copper-Gold Porphyry Target (assays pending) to date.

Highlights from Camp Creek

• Shallow drilling was successful in extending gold-silver-copper-antimony mineralization in the Northside Vein to the northeast for an estimated total strike of 800m where it remains open
• Hole THN25-325 returned 1.40m of 7.11 g/t gold, 262 g/t silver, 0.76% copper and 1840 g/t antimony from 114.10m depth
• Hole THN25-325 returned 28.35m of 1.63 g/t gold, 76.79 g/t silver, 0.61% copper and 1002.41 g/t antimony from 158.65m depth
  • Including 8.77m of 2.52 g/t gold, 120.87 g/t silver, 1.22% copper
    and 1481.78 g/t antimony from 167.73m depth

Chairman, CEO, Gary R. Thompson stated, “Shallow drilling in Camp Creek continues to deliver strong assay results. Based on these new high-grade results and the fact that the Northside Vein and Glenfiddich Zone remain open, more shallow drilling in this area is warranted to firm up continuity and define the limits along strike and at depth of this near surface gold-silver-copper-antimony mineralization. Our near-term goal is to complete enough drilling in this area to establish a resource estimate.”

Discussion

The objective of hole THN25-325 was to expand the northeast trending mineralization identified in previous drilling at the Northside Vein. Meanwhile, hole THN25-326 was targeting Oban-like diatreme breccia under-cover to the northeast.

Holes THN25-325 and THN25-326 were collared from the same pad and drilled at an azimuth of 90 degrees and 46 degrees with dips of -55 and -60 degrees and to depths of 307.00m and 214.00m, respectively. The collar was located 271m to the northeast from hole THN25-318 (Figure 1).

Hole THN25-326 did not reach its target depth of 400m and returned no significant results.

The Northside Vein mineralization has a new strike length of ~800m and has been drilled sparsely along this strike. The zone remains open along strike and at depth having estimated widths up to 20m. Mineralization consists of semi-massive quartz-pyrite-sulphosalt breccia which is hosted within the PZ diorite porphyry unit, see Figures 2, 3, and 4. Further drilling is recommended 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.

Correction: In the Company’s news release dated July 22, 2025, drill hole THN25-315 from 92.50m depth was reported in error as 0.38 g/t Au, 4.44 g/t Ag over 24.50m ; the correct result is 0.34 g/t Au, 4.61 g/t Ag over 27.50m.
