The Snuffy prospect lies in the Blue Ridge area, 1 kilometre northwest of the Voyaguere occurrence (082KSW048) and some 17 kilometres northwest of Kaslo, British Columbia.
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.
This prospect lies immediately adjacent to the contact between lithologies of the Kaslo Group volcanics and unconformably overlying Slocan Group metasediments. At this prospect the Kaslo Group consists of greenstone, mainly andesite, serpentinite, dacite and gabbro. Slocan lithologies in the immediate vicinity include tuffaceous sediments, black slate, argillite and schist.
The vein comprising the Snuffy prospect is 15 centimetres wide over a discontinuous strike length of 10 metres, hosted in andesite breccia. The vein is conformable to the hostrock foliation, similar to the neighbouring Voyageure occurrence. The best assay value from samples of the vein was 165.9 grams per tonne silver and 3.5 per cent lead (Assessment Report 13264). The sample contained 2 per cent galena and 0.5 per cent pyrite.
In 1982, Red Diamond Mines Limited completed an exploration program including soil sampling, geological mapping, and a magnetometer survey of the Snuffy and Lobo claims. Anomalous gold, silver, and nickel values were found. Geochemical values of alteration zones on the properties correlated with mineralized zones immediately north of the claims.
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.
