The Vidette gold mine is located at the north end of Vidette Lake, in the Deadman Valley. The area is approximately 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. Crown-granted Lots 4744 and 4740 forfeited May 1992.

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 Vidette mine features several narrow north-northwest striking quartz veins which dip between 45 and 70 degrees northeast (Geological Survey of Canada Memoir 179). The veins average slightly less than 30 centimetres in width, however, where they were economic they averaged 38 centimetres in width. Mineralization consists of quartz and pyrite, with some chalcopyrite and rarely tellurides. The veins are commonly ribboned with graphite seams. Wallrocks are heavily altered to ankeritic carbonate and pyrite. Five vein systems have been developed at the mine: the Tenford, Bluff, Broken Ridge, 70 and Dexheimer. The strongest, the Tenford, was followed for 275 metres on the first level and made ore over a length of 150 metres (Assessment Report 11731).

The veins were known to prospectors as early as 1898. However, active development did not take place until 1931, and following 335 metres of underground exploration and development, the mine was put into production in 1933. Between 1933 and May 1939, underground development and exploration included 199 metres of three compartment inclined shaft, 289 metres of winzes, 4984 metres of drifts and crosscuts and 1478 metres of raises (Assessment Report 11731). The mine milled a total of 48,980 tonnes of ore, recovering 1449 kilograms of silver, 929 kilograms of gold, 43,825 kilograms of copper and 161 kilograms of lead. The Dexheimer vein, located at the soutwest side of the lake, was originally explored by two short adits. During 1939-40, a tunnel was driven under the lake from the main workings and a small amount of drifting and raising done on the zone. In 1983, Consolidated Paymaster Resources Limited completed three NQ diamond-drill holes totalling 1017 metres (Assessment Report 11731). In 1984, Tugold Resources Incorporated (Assessment Report 13453) completed a program of geophysical surveying (magnetometer and VLF-EM), soil geochemical surveying (203 samples) and geological evaluation. In 1995, Discovery Consultants (Assessment Report 24060) completed a program of soil geochemical surveying (35 samples), heavy mineral stream sediment analyses (3 samples) and lithogeochemistry (11 samples).

Probable reserves remaining in the old workings in the Bluff and Dexheimer veins were estimated to total 10,160 tonnes grading 19.1 grams per tonne gold and 29.8 grams per tonne silver (Assessment Report 13453). Production between 1933 and 1940 totalled 49,980 tonnes, from which 1449 kilograms of silver, 929 kilograms of gold and 43.8 tonnes of copper were recovered.
