The Standfast Wigwam Project
The Standfast Wigwam polymetallic project is located on the western side of the Selkirk Mountains. This area represents the northwestern limit of the Kootenay Arc, a narrow belt of deformed sedimentary and volcanic rocks that is part of the structural - metamorphic transition between the Shuswap Metamorphic Complex to the west and the Selkirk Mountain Fold and Thrust Belt to the east. Several small to medium size Zn-Pb-Ag deposits, some of which have been mined, as well as numerous showings are scattered along the length of the arc.
On the Standfast Wigwam property, 34 mineralised zinc-lead showings are reported to occur over a strike length of over 3 kilometres. These showings occur mostly as conformable sulphide rich lenses within fine-grained quartzite and silicified limestone of the Cambrian age Badshot Formation of the Lardeau Group. Mineralisation is contained within the thickened hinge zone of the Drimmie Creek syncline, a large recumbent isoclinal fold. The sulphides are mainly pyrrhotite with lesser pyrite, sphalerite and galena; they occur as disseminations and in lenses up to 60 centimetres thick.
