The Hill 60 prospect lies in the Blue Ridge area, 1 kilometre northwest of the Voyaguere (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 to the immediate southwest include tuffaceous sediments, black slate, argillite and schist.
The Hill 60 prospect consists of a vein hosted in a parallel fault structure to the Nevermore vein (082KSW104). Galena and sphalerite and rare chalcopyrite comprise significant sulphides in a quartz-calcite-dolomite-siderite-mariposite vein. Pyrite is also present. Limonite, malachite and azurite occur locally as alteration of sulphides. Vein width varies from 20 to 87 centimetres over a strike length of 48 metres. The vein is exposed in old underground workings to the north where the true width of the vein is 1.25 metres. Bleaching and quartz-carbonate alteration is extensive along the footwall of the vein. Small veins also extend obliquely from the main vein. The weighted average of 16 channel samples taken at surface over an average width of 50.5 centimetres and a strike length of 48 metres is 6.31 per cent zinc, 8.78 per cent lead and 146.4 grams per tonne silver (Assessment Report 13246).
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.
