The Thorn Project is located within the Taku River Tlingit and Tahltan First Nations traditional territory. The wholly-owned 2,867 km2  Thorn Project is located in northwestern British Columbia (northern tip of the “Golden Triangle”), Canada, approximately 90 km northeast of Juneau, AK. The southwestern limit of the Thorn claim boundary is roughly 40 km from tide water.

Thorn is relatively accessible from Vancouver. A commercial flight to Whitehorse, Yukon departing in the morning allows for transfer to a fixed wing aircraft, which can land on the property airstrip by early afternoon. Access around the property is supported by helicopter from the well-established Thorn Camp.

The Thorn Project hosts a district-scale, Triassic to Eocene, volcano-plutonic complex and related sedimentary units with several styles of mineralization related to porphyry and epithermal environments.


Geological and geochemical work completed on the Thorn Project, has outlined several significant copper-gold porphyry targets across the property, in addition to epithermal mineralization and intrusion-related mineralization. Sulphide-bearing quartz and quartz-carbonate veins are common occurrences across the property, with widespread sericite and pyrite alteration. Copper mineralization is associated with chalcopyrite and lesser bornite and chalcocite. Gold mineralization occurs with pyrite, with a strong sphalerite and galena association at the Trapper Target, including rare occurrences of native gold.


Geology at the Thorn Property is defined by volcanic and sedimentary rocks of the Stikine tectonostratigraphic terrane, intruded by Triassic to Eocene volcanoplutonic rocks. In this region, the Stikine arc is composed of the Stuhini and Laberge Groups. The Stuhini Group is a Late Triassic island arc sequence comprised of massive submarine andesite and pillow basalts overlain by the Sinwa Formation, which are deep submarine clastic sedimentary rocks that shallow upwards, with increasing occurrences of limestone beds upwards. The Laberge Group is Early to Middle Jurassic in age and unconformably overlies the Stuhini Group. It is composed of 3-5 km of calcareous clastic sediments, including sandstone, conglomerate and shale. Multiple stages of subduction-related magmatism were emplaced at the Thorn Property during the Triassic, Jurassic, Cretaceous, and Eocene. At the Outlaw Zone, Jurassic-aged rhyodacite dykes are related to gold mineralization. The Golden Bear Mine gold mineralization is also Jurassic in age. The Camp Creek and Trapper mineralizing systems are Cretaceous in age. Zircon U-Pb Geochronology work at Metla indicates a Triassic-aged system.

Property History

The earliest known work on the Thorn property was carried-out by Cominco in 1952, followed by Kennco in 1959, and Chevron Minerals in the 1980’s. Brixton acquired the Thorn property in 2009 and began actively exploring in 2011. Since the original Thorn property acquisition, Brixton has continued to amalgamate claims within the region, which has produced a 2,867 km2 land package covering a district-scale, 80km Cu-Au-Ag-Mo porphyry trend. Over 315 holes have been collared on the property since 1952, totaling 74,500 meters. Brixton Metals has drilled over 58,000 meters since 2011. This work has been guided by approximately 29,000 soil samples, 9,300 rock samples and 9,300 stream sediment samples collected across the property.

Exploration Targets


Copper-gold-silver-molybdenum porphyry mineralization at the Camp Creek Target has been the focus of drilling by Brixton Metals since 2011. The target area is approximately 1.5km by 2km, and covers several different mineralized zones, including Oban, Talisker and Glenfiddich. The porphyry is blind and it wasn’t until 2019 that drilling was deep enough to connect with the veining system, starting at approximately 300m depth. Through the 2020 and 2022 exploration season, drill testing has pushed holes beyond 1,000m depths and Camp Creek is now encountering Cu-Au-Ag-Mo porphyry mineralization over 100’s of meters, including 967.71m of 0.25% Cu, 0.09g/t Au, 2.39 g/t Ag and 186 ppm Mo (0.38% CuEq*) in THN22-201, and 821.25m of 0.24% Cu, 0.10 g/t Au, 2.44 g/t Ag and 174 ppm Mo (0.38% CuEq*) in THN21-184. Brixton continues to test the extents of this porphyry system, at depth and towards the northwest, northeast and southeast.
