Brixton Metals Makes Copper-Gold-Silver Porphyry Discovery at the Tempest Target on its Thorn Project
None
The most recent news, dated December 1, 2025, announces that Brixton Metals has made a new copper-gold-silver porphyry discovery at the Tempest Target on its flagship Thorn Project in British Columbia. This is the second significant porphyry discovery in the 2025 drill season, following the Catalyst discovery announced on October 30, 2025. The Tempest target is located approximately 2 km southwest of the Catalyst target within what the company calls the Camp Creek Corridor.
Results from the first-ever drill hole at Tempest (THN25-356) included several mineralized intervals, with highlights of 90 meters of 0.33% Copper Equivalent (CuEq) and 37.38 meters of 0.45% CuEq. Chairman and CEO Gary R. Thompson stated that intersecting two mineralized porphyry systems with the first drill holes at both targets is a "remarkable achievement" and reinforces the belief that the Thorn Project could host a large, multi-center mineralized system.
This news is materially positive. It successfully follows through on the company's stated exploration plan from May 2025 to drill-test new porphyry targets, including Tempest. The discovery of a second porphyry system in close proximity to the first (Catalyst) significantly enhances the district-scale potential of the Thorn Project. It validates the company's geological model and demonstrates that the Catalyst discovery was not an isolated event.
Looking at the progression of news: - Jan-May 2025: Brixton identified the Catalyst and Tempest targets through prospecting and announced plans to drill them. - Oct 30, 2025: Brixton announced the Catalyst porphyry discovery with a long intercept of 424m of low-grade mineralization from surface. This was a significant technical success. - Dec 1, 2025: The current news confirms a second, similar discovery at Tempest.
This consistent execution and exploration success is a major de-risking event. While the grades reported are low-grade (0.33% - 0.45% CuEq), this is typical for early-stage discovery drilling in large porphyry systems. The primary goal is to identify the system; delineating higher-grade zones comes later. The use of aggressive metal price assumptions (US$4.70/lb Cu, US$3100/oz Au) in the CuEq calculation should be noted, as it inflates the reported grade.
The discovery comes shortly after the company announced a large, up to $18 million financing on November 14, 2025. This latest drill success provides a strong rationale for the financing, as the funds will be essential to follow up on both the Catalyst and Tempest discoveries in the 2026 season. The financing itself, priced at or below the market, is highly dilutive, but this positive news helps to justify the need for capital. Overall, the discovery strengthens the investment thesis by increasing the project's scale and potential.
Brixton Metals Corporation is a junior mineral exploration company focused on advancing its portfolio of projects in North America. Its flagship asset is the wholly-owned Thorn Project, a large (2,863 sq. km) district-scale exploration property located in the Golden Triangle of northwestern British Columbia. The project is prospective for various deposit types, including: - Porphyry copper-gold-molybdenum (Camp Creek, Catalyst, Tempest targets) - High-grade epithermal gold-silver (Trapper and Outlaw targets) - High-sulphidation gold-silver-copper veins (Glenfiddich and Talisker zones)
The company also holds the Langis silver-cobalt project in Ontario and has optioned its Hog Heaven silver-gold project in Montana to Ivanhoe Electric Inc. The primary focus of capital and exploration is on the Thorn Project.
