The Wild Swan showing is located 1.5 kilometres northwest of the Highland Surprise (082KSW037), on the west side of Whitewater Creek. Kaslo lies some 27 kilometres to the southeast of the showing.

The main lithologies of the area are assigned to the Permian Kaslo Group, consisting of andesite flows and pyroclastics (greenstone), and tuffaceous sediments. Volcanics are extensively chlorite altered and schistose. Slates of the Triassic Slocan Group outcrop on the neighbouring Mayflower (Lot 4458) Reverted Crown grant (082KSW078). Sediments and volcanics have been locally intruded by diorite and feldspar porphyry dikes and sills. Serpentinite is the most extensive rock type exposed in this area, forming northwesterly trending bands with steep southwest dips and extending up to 750 metres in width. Talc and asbestos are common alteration minerals associated with this serpentinite unit. The contact between the serpentinite and surrounding lithologies is faulted. The surface trace of this fault can be traced for several kilometres. Underground this fault is marked by a heavy talc gouge.

During prospecting in 1975, northeast-trending fractures or joints were found to carry chalcopyrite with nearby veins hosting pyrite, chalcopyrite and some free gold, along the eastern boundary of the Wild Swan (Lot 2510) claim.
