The Jansen property is located on the west flank of the Purcell Mountains along the east side of Kootenay Lake, on a steep west- facing slope transected by Jansen Creek, almost 2 kilometres due north of Kuskanook (Assessment Report 7845). The showings were probably worked in the early 1950s as the Cricket No. 2.
The claims are underlain by biotite hornblende granite to granodiorite of the middle Cretaceous Bayonne batholith and minor biotite quartz gneiss and schist that form roof pendants within the batholith. There are two principal quartz veins on the property, the lower at 1080 metres elevation and the upper at 1295 metres elevation. The upper vein is the largest, and is a rusty-weathering quartz vein that has been traced by an adit, trenching and blasting over a strike length of 138 metres. The vein averages 0.9 to 1.0 metres wide and strikes approximately east-west with a very flat dip of 5 to 15 degrees to the south. The hangingwall and footwall of the vein are in slightly sericite and chlorite altered granite and contain small slivers of quartz veinlets for up to 0.5 metre from the vein. Fracturing of the vein is pronounced in places but fault offsets were not observed.
Mineralization consists mainly of galena, pyrite, sphalerite, chalcopyrite and malachite with rare pyrrhotite and melanterite; the dominant sulphide, galena, is found as small isolated pods or stringers in the vein, mainly less than 5 per cent of the vein. Assays over widths of up to 1.2 metres are up to 2.1 per cent lead, 0.11 per cent zinc and 338 grams per tonne silver; all gold assays were nil. Silver assays average about 35 grams per tonne to 1 per cent combined lead plus zinc (Assessment Report 7845).
Magnetometer and VLF (very low frequency electromagnetic) surveys carried out on the property failed to show any anomalies (conductors) worthy of follow-up (Assessment Report 9316).
The adits on the property might be the documented 1951 and 1952 producers for the Cricket No. 2, which is the property near Kuskanook operated by E. Bainbridge. A 40-tonne shipment from the Mohawk No. 1 was also made in 1976.
