The Kootenay King workings are located approximately 30 kilometres northeast of Kimberley on the east side of Lakit Mountain.

Regionally, the area is underlain by Proterozoic clastic Purcell metasediments intruded by syngenetic gabbro and diorite sills and dykes of the Moyie intrusions and later intrusions of felsic and lamprophyre suites.

The Kootenay King deposit is a stratiform lead-zinc deposit. Pyrite, galena and sphalerite occur as fine laminations at the top of a coarse sandstone unit (Kootenay King quartzite) within a buff weathering section of the Helikian Lower Aldridge Formation (Purcell Supergroup). The deposit lies within the eastern overturned flank of a major anticline. The Kootenay King quartzite has a hanging wall of black argillites and a footwall of brown siltstones. The anticlinal structure plunges gently to the north.

In 2012, Klondike Gold Corp. completed prospecting at the Kootenay King workings and the surrounding area. Highlights include rock sample SKKG-97, which assayed greater than 1 per cent lead and 66.8 grams per tonne silver, and rock sample MKKG-79, which assayed 0.57 per cent lead, 0.11 per cent zinc and 27.5 grams per tonne silver (Assessment Report 33471).
