The Shannon property is located near the headwaters of Shannon Creek, 22 kilometres southeast of Nakusp. Good access is available on logging roads from the east via Shannon Creek.

There is little known about the occurrence, however, the George Cross News Letter (number 148, 1970) and Assessment Report 2966 state that the showing is a sulphide-bearing vein carrying galena, sphalerite, chalcopyrite and tetrahedrite cutting porphyry near the contact with argillite. Drillhole SH-24 intersected 4.4 metres grading 147 grams per tonne silver, 2.67 per cent lead, 1.1 per cent zinc and 0.27 per cent copper (Assessment Report 2966).

A 1929 report by Charles Starr discusses the Commodore Group at the head of Shannon Creek. According to Starr the Commodore was worked around the turn of the century when a few tons of ore were packed out. Development on the Commodore is reported as 36 metres of drifts and crosscuts in the 'west' tunnel (within porphyritic granite) and a 6-metre tunnel eastward in barren slate. The average of 3 samples taken in the east tunnel area about 1 metre is 3.09 grams per tonne gold, 603.43 grams per tonne silver, 14.4 per cent lead and 13.8 per cent zinc (Starr, 1929 (Property File)). Starr does not mention any copper mineralization.

Geological Survey of Canada Bulletin 161 shows the area to be underlain by argillite, shale, siltstone and tuff of the Triassic Slocan Group. Augite basalt of the Lower Jurassic Elise Formation of the Rossland Group outcrops 1 kilometre north of the property. Biotite hornblende quartz monzonite of the Jurassic Ruby Range stock outcrops 2 kilometres south of the area.

Documentation of the past work on the property is poor. About 4.5 tonnes of ore was shipped to the mill at New Denver in 1935. In 1970, the adit was extended to about 21 metres, 640 tonnes of "material" (George Cross News Letter number 148, 1970) stockpiled and a VLF-EM survey completed. In 1983, 54 kilometres of airborne magnetic and VLF-EM surveying was completed on the west portion of the property by Western Geophysical Aero Data Ltd. (Assessment Report 11203).
