The Vin occurrence is located at 1340 metres elevation above sea level on the south side of Glacier Creek, east of Duncan Lake in the Slocan Mining Division.

Regionally, the area lies within the Kootenay Arc near the margins of the Ancestral North American Terrane. The Kootenay Arc is a curving belt of highly deformed metasedimentary and metavolcanic rocks which includes the Upper Proterozoic Horsethief Creek Group, the Eocambrian Hamill Group, the Lower Cambrian Badshot Formation, and the lower Paleozoic Lardeau Group. The volcano-sedimentary sequence is intruded by numerous Ordovician, Devonian and Mississippian granitoid plutons. The rocks have undergone regional metamorphism to middle or upper greenschist facies (Paper 1993-1).

The Vin occurrence is in grey, massive, banded or flecked marble of the Lower Cambrian Badshot Formation which overlies the Hamill Group. The Badshot Formation is characterized by cliff-forming, white to medium grey, commonly laminated marble or dolomitic marble. The marble horizons are tens of metres thick and usually separated by grey, locally calcareous schist. The marble is overlain by a thick succession of fine grained, dark grey and green schists of the Index Formation (Lardeau Group).

Mineralization consists of disseminated pyrite, sphalerite and galena in siliceous dolomitic marble. The property has been explored with a series of trenches and seven diamond-drill holes totalling 575 metres.
