Capsule Geology

The area of the Bing Skarn occurrence is underlain by Upper Paleozoic Stikine Assemblage volcanics and limestones. These are intruded by Triassic granodioritic or quartz dioritic stocks. A small Paleocene to Eocene pluton, related to the Sloko-Hyder Plutonic Suite, consisting of high-level quartz phyric, felsitic rock occurs in the area of the Bing prospect. Widespread disseminated and stockwork porphyry copper-molybdenum mineralization in zones of feldspar-silica alteration within diorite and granodiorite (Bing (104K 032)).

Limited mapping in a skarn mineralized area suggests a potential strike length of at least 500 metres; whether or not this is continuously mineralized is not known. Observed thicknesses of mineralized skarn in outcrop are up to 20 metres.

In 2007, Paget Resources collected nine samples from skarn and calcsilicate hosted mineralization that yielded promising assay results, averaging 2.09 per cent copper, 0.037 per cent molybdenum and 0.064 per cent zinc, with the molybdenum values heavily biased by a single sample of 0.28 per cent molybdenum. Although generally low, gold and silver values are a consistently contributor to the overall tenor of mineralization, averaging 0.14 gram per tonne gold and 28.2 grams per tonne silver (Assessment Report 29345).

Rocks were described as quartz flooded volcanic breccia with 5 per cent copper mineralization consisting of chalcopyrite, chalcocite and bornite. Another sample was of sedimentary rock, partly intruded by diorite with 10 per cent pyrite stringers associated with quartz stringers, k-feldspar alteration envelopes and 2 to 3 per cent magnetite.

In 2019, Brixton Metals Corporation expanded their Thorn property through staking and acquisition of several claims over their East Target area which contained seven mineral showings including Ant (104K 032), Bing (104K 035), East Ant Diorite (104K 152), Skarnface (104K 153), Bing Skarn (104K 166), Motherlode2 (104K 183) and Motherlode1 (104K 190).

In 2020 Brixton completed 3,025 metres of drilling within 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 (Press Release, Brixton Metals Corp., Dec.15, 2020). Brixton's East Target eastern copper-in-soil anomaly is about 3 kilometres east-west and 4 kilometres north-south. Like the East Target's western soil anomaly, the eastern soil anomaly has a minimum of 100 parts per million copper and contains a significant central area (elongate along a northwest-southeast axis) that is greater than or equal to 200 parts per million copper (see Figure 7, Press Release, Brixton Metals Corp., Dec.15, 2020). The Bing Skarn showing is located within the eastern soil anomaly (East Target) about 800 metres southeast of its northwest boundary.

Refer to Thorn (104K 031), Chivas (104K 180), East Outlaw (104K 083) and Oban (104K 168) for details of the work history on the greater Thorn property. Refer to Bing (104K 032) for details of a common property work history. See Motherlode1 (104K 190) for details of the western soil anomaly (East Target).
