The Kaslo occurrence is located on Crown grant Lot 2432 at 1340 metres elevation above sea level, in the Slocan Mining Division. The claim is on Carpenter Creek, just east of Cody Creek.
Regionally, the area lies on the western margin of the Kootenay Arc, in allochthonous rocks of the Quesnel Terrane. In the vicinity of the occurrence, the Quesnel Terrane is dominated by the Upper Triassic Slocan Group, a thick sequence of deformed and metamorphosed shale, argillite, siltstone, quartzite and minor limestone. Rocks of the Slocan Group are tightly and disharmonically folded. Early minor folds are tight to isoclinal with moderate east plunging, southeast inclined axial planes and younger folds are open, southwest plunging with subhorizontal axial planes. The sedimentary sequence has been regionally metamorphosed to lower greenschist facies.
South of the occurrence, the Slocan Group has been intruded by the Middle Jurassic Nelson intrusions which comprise at least six texturally and compositionally distinct phases ranging from diorite to lamprophyre. The most dominant phase is a medium to coarse grained potassium feldspar porphyritic granite. Several feldspar porphyritic granodiorite dikes, apparently related to the Nelson intrusions, also cut the sedimentary sequence near the occurrence (Paper 1989-5).
The Kaslo property is underlain by argillite of the Slocan Group and several quartz porphyritic dikes which are probably related to the Nelson intrusions. Two narrow, north trending fissure veins have been explored on the Kaslo claim. The veins are 20 to 30 centimetres wide and about 75 metres apart. A short adit has been excavated on the western vein and a grab sample collected from the dump near the adit portal in 1971 assayed 78 grams per tonne silver (Property File - The Potential of Reco Silver Mines Ltd.). Although not mentioned specifically, the vein is probably similar to the vein found on the Chambers Crown grant (082FNW032) and probably contains mostly galena with minor sphalerite.
