The Bluebird showing is located on the northeast side of Harris Creek about 5.6 kilometres southeast of its confluence with Bessette Creek and about 6.5 kilometres south of Lumby.

A series of shallow exploratory opencuts, probably from 1949, expose small quartz veins.

The area is underlain by sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group which have been intruded by granitic rocks of the Jurassic Nelson Intrusions. The Harper Ranch Group comprises tuffaceous mudstone, chert, limestone, sandstone and conglomerate.

The veins occur in both sedimentary and plutonic rocks. Most of the veins are less than 15 centimetres wide but locally some are up to 60 centimetres wide. The veins, which contain wallrock inclusions, strike northeast and are vertically dipping. The wallrock is reportedly "much altered and decomposed".

A sample of rusty quartz across 15 centimetres assayed 34.97 grams per tonne gold and 3.43 grams per tonne silver (Minister of Mines Annual Report 1949, page 137). Other samples assayed trace to 14.06 grams per tonne gold (Minister of Mines Annual Report 1949, page 137).
