The Voyageure occurrence is located in the Blue Ridge area, 2 kilometres southeast of Mount Jardine and roughly 20 kilometres northwest of Kaslo, British Columbia.
The Voyageure occurrence consists of veins and veinlets of quartz-carbonate-sulfide ranging from 0.05 to 5 centimetres in thickness and coarsely crystalline, white, quartz veins without carbonate, displaying trace to 2 percent sulfides measuring up to 1.25 metres in thickness (Thomson, G. (2007-07-23): Compliance Report on the Emerald Property).
Silver-lead-zinc mineralization occurs in the Triassic Slocan Group, locally consisting primarily of black fissile phyllites with interbedded limestone, calcareous phyllites and brown gritty quartzites. The general structural trend is 310 degrees, dipping generally southwesterly. Greenstones and ultramafic rocks of the Permian Kaslo Group unconformably underlie the Slocan Group to the east, also hosting silver-lead-zinc mineralization. Satellite stocks, dikes and sills are generally correlative with the Nelson batholith to the immediate south. Late stage lamprophyre dikes are also common.
The past producer lies within the Kaslo Group. Three adits comprise workings at the Voyageure. Numerous quartz stringers and lenses are hosted in ankerite, carbonate, quartz and mariposite altered and sheared greenstone. Mineralization within quartz veins consists of sphalerite, galena and chalcopyrite. Pyrite is also present. Sphalerite has a resinous appearance akin to many other occurrences in the Kaslo Group.
In 1946, samples of galena were reported to contain 4.54 grams per tonne gold, 297.7 grams per tonne silver, 53.3 per cent lead and 6.4 per cent zinc. Samples of chalcopyrite were determined to contain 9.1 grams per tonne gold, 96.4 grams per tonne silver, 4 per cent lead and 0.5 per cent zinc (Minister of Mines Annual Report 1946, page 156). At this time surface stripping was found to be a more favourable mining method and in 1949 the first shipment was made to the Trail smelter. A total of 54 tonnes of crude ore yielded gross contents of 312 grams gold, 14,175 grams silver, 8036 kilograms lead and 6451 grams zinc (Minister of Mines Annual Report 1946, page 156).
In 2006, Rio Minerals Limited for Cavan Ventures Incorporated completed an exploration program consisting of grid surveys, soil and silt geochemical surveys, rock sampling, and geological mapping. Soil and silt geochemistry gave overlapping anomalies to historic findings at Emerald and Voyageur areas. Specifically, lead, copper, and antimony patterns at the Voyageur locality. Two general trends of single element anomalies were observed. The first, an arsenic anomaly of a broad N-S trending zone along the eastern edge of the grid. The second, a silver anomaly of a broad WNW trending zone. Anomalous gold found in soil and silt sampling correlates poorly with lode mineralization of the area, but instead defined a broad, contiguous, NNW trending zone between Emerald and Voyageur locations.
