The Black Jacket showing is located on the south western side of La Forme Creek, approximately 25 kilometres north of Revelstoke. The showings were discovered in 2008, during prospecting on the Allco-Redtop-Slide Project of Rich River Exploration Ltd. Over the next couple of years, a program of geochemical and geological surveys was completed.

Locally, a mineralized zone occurs in gneissic rocks of the Early Mississippian Clachnacudain gneissic package, south of the Standfast Creek fault. The mineralized zone is approximately two metres wide and consists of several 10 to 30 centimetre wide bands of massive galena, sphalerite, and arsenopyrite with minor chalcopyrite and possibly tetrahedrite. Also, several quartz veins mineralized with pyrrhotite and chalcopyrite occur in the vicinity.

In 2010, preliminary sampling of the showing returned up to 100 parts per billion gold and 1120 parts per million zinc (Assessment Report 32051).
