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


The wholly-owned 2,600 square kilometres Thorn Project is located in northwestern British Columbia (northern tip of the “Golden Triangle”), Canada, approximately 90 km northeast of Juneau, AK. The southern limit of the Thorn claim boundary is roughly 50 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 aircrafts, which can land on the airstrip at the property by early afternoon. Access around the property is supported by helicopter from the well-established Thorn Camp.

Property History

The earliest known work on the Thorn property was carried out by Kennco in 1959 as part of a regional exploration program. Including work from Brixton since 2011, a total of 31,070 soils, 8,185 rocks and  1,203 stream sediment samples have been taken on the property. Geophysical work includes 65 line-kilometres of induced polarization, 9 line-kilometres of MT, 467 line-km of airborne EM, 80 square kilometres of airborne radiometrics and 200 square kilometres of airborne magnetics. 768 square kilometres of LIDAR surveys were completed and property-wide ASTER-SENTINAL 2 data was acquired. 40,000 m of diamond drilling to date among 220 drill holes. 

Exploration Targets

  • Mineralization at the Camp Creek is within a 2km by 1km area has been the main focus of drilling by Brixton Metals thus far. However, it was only in 2019 that drilling was deep enough to test the blind porphyry.  Deeper drilling in 2019 and 2020 encountered porphyry-style veining beginning at depths of roughly 300m-500m. THN20-181 returned 439m of mineralized porphyry Cu-Au-Ag-Mo. Further drilling is needed to determine the extent of this mineralization. The 2021 plan is to drill test the Camp Creek porphyry in several locations, starting with extending hole 181 to greater depths.
  • The Oban zone is a porphyry-related diatreme breccia where polymetallic (Au-Ag-Cu-Pb-Zn) mineralization is hosted in the breccia matrix. Subrounded clasts are composed mostly of quartz diorite porphyry, some of which contain mineralized porphyry-style veining. Hole 150 drill tested the diatreme to 829m depth where 554m was ~2 g/t AuEq.
  • The Glenfiddich zone consist of high-sulphidation veins and silica-flooded breccia hosting high Cu-Ag-Au. Intense silicification with vuggy texture is exposed on several outcrops at surface and is host to pyrite, tetrahedrite and enargite. Hole 121 drilled 10.6% Cu, 583 g/t Ag, 2.5 /gt Au over a true width of 1.1m
  • The Talisker zone is defined by a northeast striking high sulphidation vein corridor. It has strike length of 600 m and is open to the northeast. Disseminated and vein-hosted pyrite and sulphosalts with strong sericite alteration yield significant Au-Cu-Ag values. The best Talisker hole returned 49m of 2.2 g/t AuEq.
