The Swan 6 occurrence is located at an elevation of approximately 1700 metres in the headwaters of a tributary of Saunders Creek, approximately 9.5 kilometres southwest of the west end of Toodoggone Lake.

The area lies within the Omineca-Cassiar Mountains at the southern end of the Toodoggone gold camp. It occurs within a Mesozoic volcanic arc assemblage that lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Neogene sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. Takla volcanics have been intruded by Lower Jurassic granodiorite to quartz monzonite of the Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calc-alkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults that define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high-angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The occurrence area is underlain by Toodoggone Formation volcanic rocks of the upper volcanic cycle. These consist of a heterogeneous mixture of green, grey and mauve lapilli ash and lesser block tuff, with lesser interspersed ash flows and lava flows and interbedded epiclastics of the Attycelley member; partly welded, crystal-rich dacitic ash flows of the conformably overlying Saunders member and andesitic volcanic rocks of the Metsantan member.

Locally, a propylitic-altered crystal tuff hosts chalcopyrite and malachite.

In 2006, a grab sample (6187) assayed 0.330 gram per tonne gold, 22.3 grams per tonne silver and 0.519 per cent copper, whereas a chip sample (6188) over 0.4 metre yielded 0.150 gram per tonne gold, 11.2 grams per tonne silver and 0.255 per cent copper (Assessment Report 28645).
