The Vid 27 occurrence is located on the east side of Vidette Lake, southeast of the Vidette mine (092P 086). The area is about 50 (air) kilometres north of Savona and is accessible on a good-quality gravel road which leads north from the Trans-Canada Highway approximately 7.4 kilometres west of Savona.

The Vidette Lake area is underlain by mafic volcanic rocks of the Upper Triassic Nicola Group exposed in a window eroded through flat-lying Miocene sedimentary rocks and plateau basalts of the Chilcotin Group. The uppermost Chilcotin Group strata comprise an extensive layer of plateau basalts of the Chasm Formation, underlain by volcanic ash and fluviatile and lacustrine sedimentary strata of the Deadman River Formation which occupy a northwest trending Miocene channel. The Nicola rocks are intruded by biotite-hornblende granodiorite plugs which are possibly related to the Triassic to Jurassic Thuya batholith. Nicola rocks are generally augite andesites commonly altered to chlorite-rich or calcareous greenstones, however contact metamorphism has developed garnet-diopside-actinolite skarn or tactite adjacent to the intrusive rocks.

The Vid 27 occurrence is located 1500 metres southeast of the Vidette mine (092P 086). Assessment Report 4257 (page 8) states that there are a large number of prospect pits, most of which are now sloughed in. However, pyrite and chalcopyrite were noted in several spots where bedrock is visible. On the boundary between Vid #27 and Vid #28, a small pit was cut on an 8 inch (20 centimetre) quartz-carbonate vein which carries abundant pyrite and minor chalcopyrite. A selected sample from the vein assayed 0.14 ounce per ton gold (4.8 grams per tonne), 0.26 ounce per ton silver (8.9 grams per tonne) and 0.35 per cent copper (Assessment Report 4257).

The first record of work (Geological Survey of Canada Memoir 179) was in the 1930s on the Shelley property (092P 088) when the property was explored by several pits and an adit. More recently the property has been covered by several soil geochemical and geophysical surveys (Assessment Reports 4257, 12021, 17810, 18492, 19136).
