The Sail (Storm) showing is located approximately 10 kilometres east-southeast of the northern end of Cry Lake, and about 65 kilometres east of the Stewart-Cassiar Highway (37). The nearest community is Dease Lake, located 80 kilometres southwest of the property.
The area is primarily underlain by strongly metamorphosed and deformed metasedimentary (quartz-biotite gneiss) and metavolcanic rocks (chlorite-feldspar gneiss) with minor interlayered felsic volcanic units, of the Precambrian to Devonian Rapid River Tectonite. These are intruded and/or tectonically interleaved with Devonian to Permian ultramafic bodies and intruded by granitic stocks and dikes of the Eocene Major Hart pluton.
The Storm showing comprises gossans with associated sulphide mineralization that occur along a specific stratigraphic unit, the contact between chlorite gneiss and a fine grained, cherty, biotite-rich quartzite about 25 metres thick. The quartzite structurally underlies the mineralized horizon. The quartzite contains abundant subhorizontal, isoclinal to open folds an average of 10 to 20 centimetres across. The stratigraphic sequence is likely overturned. The mineralized horizon is a garnet-biotite-quartz gneiss up to 6 metres thick that extends for 43 metres along a strike of 015 degrees at the main showing area. The mineralized horizon extends 250 metres along strike to the south where it is cut off by a steep fault trending 076 degrees. Numerous gossans are present around the perimeter of the cirque in which the showing is located; these may be expressions of mineralized horizons.
The host garnet-biotite-quartz gneiss contains subhedral to euhedral, red, spessartine garnets that average about 3 millimetres diameter. Syndepositional faulting may have occurred where the garnet-biotite-quartz gneiss is best mineralized. The mineralized gneiss here contains up to about 35 per cent pyrite, 3 per cent pyrrhotite and up to 2 per cent chalcopyrite within a steeply dipping band or fault shear 30 centimetres wide. The sulphides are very finely disseminated and faintly banded. Subrounded fault breccia (or lapilli?) fragments up to 3 centimetres across have locally been mineralized with very fine grained, disseminated pyrite within the steeply dipping band or shear. The mineralized horizon averages 1 to 5 per cent disseminated pyrite. Select samples BE2070 and BE2070A were collected from the best mineralized portion of the showing and yielded up to 0.25 per cent copper, 95 parts per million zinc, 50 parts per million lead and 1 gram per tonne silver (Assessment Report 25932).
In 1996, the Sail claims were staked by Westmin Resources Ltd. to follow-up on base metal anomalies generated during silt sampling surveys by Western Mines Limited (Westmin Resources Limited’s precursor company) in 1979 and the British Columbia Geological Survey in 1995. A number of rock and soil samples containing anomalous concentrations of gold and base metals were identified during 1996 exploration. In 1997, fieldwork comprised grid geochemical soil sampling on contour soil anomalies delineated during 1996. Mineralized float boulders containing massive sulphides were discovered; these boulders contain up to 15 per cent chalcopyrite and 65 to 80 per cent pyrrhotite within a silica-chlorite gangue. The bedrock source of the boulders was not determined in 1997 due to extremely steep topography in the apparent source area. In 1998, additional claim staking, grid geochemical soil sampling, geological mapping and rock sampling were completed to determine the source of the mineralized massive sulphide boulders and lead- and zinc-in-soil anomalies. Several mineralized showings were discovered as a result of this program (Beale (104I 133), Slot (104I 134), Vader/ South Vader (104I 135), Ice (104I 136) and Storm).
In 2013, Kaminak Gold Corporation conducted exploration on their Sail property which covers the Slot (104I 134), Vader/South Vader and Beale (104I 133) showings. The work consisted of a very minor amount of geochemical sampling on the Sail (Beale) showing to attempt to confirm showing samples. The property visit was conducted late in the year and snow cover limited the ability to properly identify a number of the showings mineralized rocks.
