Five claims of the California group were staked in March 1949 to cover mineralization astride the Canadian Pacific Railway near Wynndel. A trial shipment of 8 tonnes was made to the Trail smelter in November of 1949 that assayed 122 grams per tonne silver, 5.5 per cent lead and 0.6 per cent zinc (Minister of Mines Annual Report 1949, page 194). No further description of the property is available, but by comparison to the Peggy vein one kilometre to the south along the railway, it is likely that the California showing consists of a quartz vein with galena and sphalerite in mica schist of the Middle Proterozoic Middle Aldridge Formation.
