The Switchback showing is located 2.8 kilometres west of Roundtop Mountain, on the west side of Cunningham Creek about 20 kilometres southeast of Barkerville. Access is via well maintained forest service and logging roads. The showing is about 190 metres east of the Canadian showing (093A 106).

The showing is near the north end of a belt of mineralized quartz veins, hosted by Downey succession quartzites and phyllites of the Upper Proterozoic-Paleozoic Snowshoe Group, that extends for 5.5 kilometres north-northwest from the past-producing Cariboo Hudson mine (093A 071). At the Switchback showing, several quartz veins and lenses, some mineralized with pyrite and galena, were documented through trenching and 2 short diamond-drill holes. Galena-bearing veins have yielded assays of up to 39.73 grams per tonne gold and 356.1 grams per tonne silver across 1 metre (Assessment Report 19793).

In 1989, Loki Gold Corporation conducted an exploration program on the ground now within the Golden Cariboo property. This included detailed geological mapping, soil sampling, trenching and sampling, followed by drilling on the Jewellery Shop, Hibernian and B-Zone polymetallic vein showings (093A 051) near the confluence of Craze Creek and Peter Gulch Creek. They also drilled the Switchback showing on the west side of Cunningham Creek.

During 2000 through 2008, Golden Cariboo Resources Ltd. completed programs of prospecting, geological mapping, geochemical (rock, soil, moss and stream sediment) sampling, ground magnetic and self potential surveys, trenching and 60 diamond drill holes, totalling 28,710.0 metres on the area as the Golden Cariboo property. A complete summary of exploration programs can be found at the Cariboo Hudson (MINFILE 093A 091) occurrence.

In 2004, a sample (166308) quartz vein with pyrite assayed 21.4 grams per tonne gold, greater than 30 grams per tonne silver and 0.134 per cent lead (Brown, J. (2009-01-28): Technical Report on the 2000-2008 Exploration Programs on the Golden Cariboo Project).
