The Kootenay Belle showing is located 18 kilometres from Kaslo, British Columbia, immediately south of the confluence of Twelve Mile Creek with the Kaslo River. The showing consists of the two old Crown Grants on old adits and surface workings, Kootenay Belle and Crown Point circa 1915.

Silver-lead-zinc mineralization occurs in the Triassic Slocan Group, locally consisting primarily of black fissile phyllites with interbedded limestone, calcareous phyllites and brown gritty quartzites. The general structural trend is 310 degrees, dipping generally southwesterly. Greenstones and ultramafic rocks of the Permian Kaslo Group unconformably underlie the Slocan Group to the east, also hosting silver-lead-zinc mineralization. Satellite stocks, dikes and sills are generally correlative with the Nelson batholith to the immediate south. Late stage lamprophyre dikes are also common. Limestone, limy quartzite, fissile and slaty argillite comprise hostrocks at this showing.

The Kootenay Belle workings consisted of two adits and surface opencuts exploring two small fissures. One fissure is coincident with bedding while the other crosscuts at 082 degrees dipping 50 degrees east. Quartz veins follow these fissures and are most prominent at the intersection of these two fissures. Mineralization was observed in outcrop above the adits, consisting of minor disseminated galena over 0.45 to 0.60 metre width. Elsewhere, galena and siderite were observed in oxidized outcrop replacing limy quartzite along bedding planes. No mineralization was noted in 38 metres of adit on the Crown Point.
