The Bluebird showing is located about 2.5 kilometres southeast of Nakusp (Minister of Mines Annual Report 1927; GSC Open File 432).
The 1927 Annual Report states that a prospect tunnel was driven east for 88 metres on a faulted and "broken" quartz vein cutting "slate-schists". There is no information regarding the mineralogy of the vein other than "small pieces of ore have been encountered" (Minister of Mines Annual Report 1927). It is tabulated as number 239 in GSC Open File 464, where it is stated to contain silver, lead, zinc and copper.
GSC Bulletin 161 shows the area to be underlain by pelitic to silty phyllite and slate of the Triassic Slocan Group.
