This prospect is located on the west flank of Raven Mountain, a northwest-trending ridge between Steven Creek and its southward flowing tributary, 18 kilometres east-northeast of Princeton.

Raven Mountain is underlain by a roof pendant of intermediate to mafic volcanics of the eastern facies of the Upper Triassic Nicola Group. This roof pendant continues northwest between Steven Creek and its tributary for 5 kilometres, within the northern margin of the Early Jurassic Bromley batholith.

The southern end of the pendant, in the vicinity of Raven Mountain, is comprised of andesite, with minor tuff and argillite. These rocks strike slightly west of north and are steeply dipping. The surrounding intrusives of the Bromley batholith consist of grey, coarse-grained, siliceous granite and granodiorite. The granite is oxidized, altered and mineralized with abundant magnetite along the western margin of the roof pendant.

Galena and sphalerite are exposed in a series of shafts, trenches and outcrops in an area extending north along the west side of Raven Mountain for up to 1400 metres. Other trenches to the west and east contain only pyrite. This mineralization is in part contained in quartz veins that are conformable to the enclosing volcanics and sediments. Samples assayed 1.4 to 6.9 grams per tonne gold and 103 to 1234 grams per tonne silver (Minister of Mines Annual Report 1934, page D23). A selected sample of quartz with stronger mineralization assayed 21 per cent lead and 5 per cent zinc (Minister of Mines Annual Report 1934, page D23).

The prospect was initially explored by a number of trenches, shafts and adits in 1934 and 1935. Adco Silver Mines Ltd. completed a magnetometer survey in 1970. Coynex Development Ltd. conducted additional magnetometer surveying, in conjunction with geological mapping, soil sampling and stripping in 1972.
