The South Slocanny Granny occurrence is located on a northeast-facing slope, between the historical Duplex (L.3232) and Robber King (L.3626) Crown-granted claims and approximately 2.2 kilometres south of White Grouse Mountain.
Regionally, the area is underlain by siltstones, quartzites, dolomites and phyllites of the Proterozoic Aldridge, Creston and Kitchener formations of the Purcell Supergroup, intruded by a small quartz monzonite stock, possibly Cretaceous. Buff dolomites, white-grey quartzites and minor argillites of the Kitchener Formation have a northward strike and dip moderately to steeply west. The Lower Creston Formation consists mainly of laminated to thickly bedded argillites and siltites with minor fine-grained quartz wackes. The rocks are waxy green to olive in colour with tan-weathering surfaces, wavy bedding and abundant mudcracks. Rocks of the Upper Aldridge, underlying an area to the east, consist of a relatively homogeneous unit with occasional thin interbeds of light grey quartzite and laminated light and dark grey argillaceous quartzite. The intrusive stock consists of medium- to fine-grained massive biotite monzogranite. The sediments adjacent to the intrusion have been altered to produce concentric zones of biotite hornfels and siliceous siltstone.
Locally, a 0.3-metre quartz vein in limestone and dolomite hosts tetrahedrite and malachite.
Work in 2010 identified zones of quartz veining and alteration within a phyllitic shear, quartz-magnesite veins bearing base metals in a carbonate unit and zones of brecciation and quartz-sulphide veining and stockworks in brecciated quartzites adjacent to a greenstone dike within a fold closure. The breccia zone is reported to be greater than 15 metres in width.
Work History
The area has been explored in conjunction with the nearby Copper King (L.3835; MINFILE 082FNE065) occurrence and a complete exploration history of the area can be found there. A historical adit, likely dating to the late 1890s or early 1900s, is reported in the occurrence area.
In 1980, the area was prospected as part of the White Grouse property by Gerhardi Holdings Ltd.
In 1985, Lacana Mining prospected and sampled the area as the Whiskey Jack claim. A rock sample (JWR-002) assayed 0.50 per cent copper, 0.18 per cent antimony, 44.5 grams per tonne silver and 0.28 gram per tonne gold (Assessment Report 14125).
In 2006, Aeroquest Limited carried out an airborne geophysical survey on the area as the Storm King property, owned by Jasper Mining Corporation and held under option by Dynamic Exploration Limited. In total, 96.2 line-kilometres of electromagnetic, magnetic and radiometric surveys were flown over the property.
In 2010, Kootenay Gold Inc. conducted a minor program of prospecting and rock sampling and the area as the Slocanny Granny property. Fjordland Exploration Incorporated optioned the property later that year. Two rock samples (SK10-352 and Mk10-356) from the occurrence area yielded values of up to 1.51 per cent copper, greater than 0.20 per cent bismuth, 0.094 per cent antimony, 0.034 per cent tellurium, 50.6 grams per tonne silver and 0.16 grams per tonne gold (Assessment Report 32262).
In 2011, Fjordland Exploration completed a program of soil sampling on the South Slocanny Granny property.
