Brixton Metals Commences 2026 Thorn Project Exploration Program

Executive Summary

• Brixton Metals has commenced its fully funded 10,000-meter 2026 exploration drilling program at its wholly owned Thorn Project in northwestern British Columbia.
• Initial drilling has completed 249 meters across three holes, with an immediate focus on expanding the Camp Creek high-sulphidation and porphyry systems.
• The program targets multiple copper-gold porphyry systems (Catalyst, Tempest, Sentinel, and East Targets) and aims to support future mineral resource estimates through drilling, geophysics, and geo-metallurgical testing.

Key Details

• Program Scope: Fully funded 10,000-meter 2026 exploration drilling program at the Thorn Project.
• Location: ~90 km east-northeast of Juneau, Alaska, and ~120 km west of Dease Lake, British Columbia.
• Initial Progress: Drilling commenced June 1, 2026; 249 meters completed in three holes.
• Camp Creek Objectives: Expand the known near-surface high-sulphidation Cu-Au-Ag zone by drilling north and south; complete an updated mineral resource estimate for the Camp Creek porphyry; evaluate continuity, orientation, and controls of mineralized structures (Glenfiddich, Northside, Talisker vein systems, and Oban Breccia).
• Catalyst & Tempest Targets: Recently discovered Cu-Au porphyries showing intermittent mineralization from surface to depths exceeding 500 meters; 2025 IP survey delineates km-wide high-chargeability zones and a km-wide Cu-in-soils footprint within the "Camp Creek Corridor".
• Sentinel Target: Priority Cu porphyry target defined by a broad alteration footprint, porphyry-style stockwork veining, and surface rock sampling returning up to 1.54% Cu and 0.54% Mo.
• East Targets (Icy & Bing): Historical Newmont drilling (1965-1966) identified Cu-Mo mineralization; Bing shows Cu values ranging from 1,000 to 30,000 ppm in localized areas; Icy shows weak to moderate Cu-Mo mineralization with disseminated pyrite, chalcopyrite, and molybdenite near feldspar biotite porphyry dykes.
• Geophysical & Field Work: Ongoing 16-line-km magnetic survey and drone magnetic surveying (70% complete to date), plus mapping, soil geochemistry, and geo-metallurgical testing to refine drill targets and support resource updates.
• Qualified Person: Duncan McBean, VP Exploration, verified all technical data per NI 43-101.

Notable Quotes

• Gary R. Thompson, Chairman & CEO: “We are excited to kick off another exploration season at Thorn with an initial focus on Camp Creek, Catalyst, Tempest, Sentinel, and Trapper. This fully funded program is designed to advance several priority targets through drilling, geophysics, and fieldwork, while also supporting progress toward future mineral resource estimates at Camp Creek and Trapper.”
