The Kalispell occurrence is located on Enterprise Creek, about 1 kilometre from its mouth on Slocan Lake. Silverton, British Columbia lies 10 kilometres to the north-northeast.

The Kalispell occurrence is covered by the Kalispell group, composed of the Kalispell (Lot 1011), Kalmar (Lot 1012) and Kaiser (Lot 1254) Reverted Crown grants.

The first production from the Kalispell occurred in 1896 and 1897. The workings consisted two adits, for a total of 76 metres. In 1974, McCormick Electric Ltd. carried out a program of diamond drilling and trenching. The property was owned by P. Leontowicz. No further production was recorded until 1975 when 36 tonnes of ore from the dump were shipped. In 1985 and 1986, exploration on the property included a geochemical soil survey and two diamond-drill holes, totalling 258 metres. The property was owned by Silver Hoarde Resources Inc.

The workings were driven along a shear and faulted zone in a small roof pendant of Lower Jurassic Rossland Group metasediments. Limy and quartzitic argillite comprise metasediments of the Rossland Group intersected in the main adit. The roof pendant is hosted in coarse grained potassium feldspar porphyritic granite of the Middle Jurassic Nelson batholith. The zone strikes 015 to 040 degrees and dips 50 to 60 degrees to the southeast. It is about 9 metres wide and walls are well defined. Hostrocks are well brecciated and cemented with milky quartz. Mineralization hosted in quartz cement includes galena, pyrargyrite, sphalerite and pyrite. Diamond drilling in 1986 confirmed the downward dip of the shear zone up to 61 metres, along a strike length of 61 metres. Sericitic, argillic and silicification alteration were observed.

Shipments of 10 and 5 tonnes were made in 1896 and 1897, respectively. In 1975, clean-up from the dump resulted in a shipment of 36 tonnes of ore. In total 123,447 grams silver, 323 kilograms lead and 143 kilograms zinc were recovered from 51 tonnes of ore.
