The Leadville or Star property is on the east side of Goat River, 6 kilometres north of Kitchener. Several exposures of veins have been found extending from the river bottom up the east slope to an elevation of 1370 metres.

The veins are described as being hosted in quartzites of the Aldridge Formation intruded by gabbro of the Moyie intrusions, both units belonging to the Purcell Supergroup of Middle Proterozoic age. Thinly bedded quartzites strike east-northeast and dip 20 degrees to the north. The veins, described variously as quartz-filled fissures and quartz-calcite veinlets, are up to 0.5 metre wide and cut the sedimentary rocks on the dip but are parallel in strike, in close proximity or in places within the gabbro sill. In 1925, the vein had been exposed over a continuous length of 23 metres, dipping 72 degrees to the south.

The veins are irregularly mineralized with galena and minor amounts of sphalerite, chalcopyrite and a little pyrite. Carbonate alteration of the wallrock, likely calcite, accompanies the vein in places and may account for the locally schistose character of the hostrock. Maximum assays from dump material are up to 720 grams per tonne silver, 61.1 per cent lead, 10.2 per cent zinc, 0.05 per cent copper and 1.4 grams per tonne gold (Minister of Mines Annual Report 1923, page 220).
