A gossanous zone of copper-molybdenum mineralization is exposed in the headwaters of an unnamed creek, 2.5 kilometres southwest of the peak of Mount Louie, 3.8 kilometres east-southeast of Killam Bay. The Red Jacket showing is hosted in a roof pendant of metavolca- nics and metasediments of the Lower Cretaceous Gambier Group engulfed in diorite of Cretaceous age, within the Jurassic to Tertiary Coast Plutonic Complex A steeply dipping shear zone strikes northeast for 350 metres and varies up to 180 metres in width. The zone is mineralized with chalcopyrite, pyrite and pyrrhotite with minor molybdenite occurring as disseminations and as fracture-fillings paralleling the foliation of the host rock. A chip sample across 1.8 metres assayed trace of gold, 21 grams per tonne silver and 0.5 per cent copper (Minister of Mines Annual Report 1917, p. 284).
