The Westarg 1 showing is located roughly 35 kilometres east-southeast of Mount Ericksen, roughly 13 kilometres north-northwest of Tunjony Lake.

The Westarg 1 showing area is underlain by a Paleocene to Eocene batholith of the Sloko-Hyder Plutonic Suite composed of granite and alkali feldspar granite. The batholith intrudes Upper Triassic volcanic rocks of the Stuhini Group, Upper Paleozoic rocks of the Stikine Assemblage and Lower Jurassic sedimentary rock of the Takwahoni Formation, Laberge Group. A rock sample collected in 2020 graded 3.1 per cent copper; another rock sample collected about 650 metres to the southwest graded 2.6 per cent copper (Figure 5-15, Press Release, Brixton Metals Corp., Dec.15, 2020).

In 2020 Brixton Metals Corporation completed 3,025 metres of drilling in 16 core holes on the new Central Outlaw and West Outlaw zones on their Thorn property. A total of 1473 rock samples and 5588 soil samples were also collected throughout their expanded Thorn property including from the West Target area that contains the new Westarg showings and the BS-J (104K 029) and Park 13 104K 158) showings.
