The Blue Jay showing is located 3 kilometres north-northwest of Vernon.

In this area, west of the Okanagan Valley fault zone, volcanic and sedimentary rocks of the Devonian to Triassic Harper Ranch Group are unconformably overlain by Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. These units are intruded by Middle Jurassic granitic rocks. Patches of Eocene Penticton Group volcanic rocks overlie the older rocks.

A quartz vein in Nicola andesite flows, tuffs and breccias hosts gold, lead and copper mineralization. Disseminated pyrite, arsenopyrite, and minor galena, tetrahedrite and native gold are reported. The vein, 1.4 metres thick, is traceable for 30 metres. A two-centimetre graphitic clay fault gouge on the hangingwall contains higher gold values than the vein. Gold values from selected sampling were up to 140 grams per tonne (Assessment Report 4960).

By 1899, a 13-metre shaft and a 53-metre adit were completed. The claim was Crown-granted in 1898. Additional exploration was reported in 1934.
