Capsule Geology

The Sutlridge occurrence is located approximately 5.3 kilometres south of King Salmon Lake.

The Sutlridge showing is located at or near the contact of andesitic volcanic rock of the Lower Jurassic Takwahoni Formation (Laberge Group) and volcanic rock of the Upper Triassic Stuhini Group. High-level quartz-phyric, felsitic intrusive rocks of the Paleocene to Eocene Sloko-Hyder Plutonic Suite intrude the older strata.

The area of the Sutlridge showing was held by Brixton Metals Corporation in 2017 as part of their Thorn property, at which time they ran reconnaissance soil lines along the mountain ridges east and north of the Mag showing (104K 028) and south of the Sutl showing (104K 146). The soils were anomalous in gold, silver and copper along this part of the ridge, especially in the vicinity of the two rock samples taken. Rock sample S044601 was an outcrop grab of rusty, very altered volcanic breccia with 1 per cent pyrite that graded 0.06 grams per tonne gold, 12 grams per tonne silver and 0.06 per cent copper (Assessment Report 36829). Some crosscutting calcite veins were observed. The sample was described as being very hard.

See Sutl (104K 146) for local work history and Camp Creek Corridor (104K 116), Oban (104K 168) and Thorn (104K 031) for related geological and historical details of the Thorn Property.
