Development Status: Prospect
Name: KASHUTL INLET, WOOD COVE
Limestone outcrops along the cliffs and on the west side of Kashutl Inlet, 4.5 kilometres south of the head of the inlet on the west coast of Vancouver Island.
The occurrence lies in a broad belt of Lower Jurassic Bonanza Group volcanics and sediments, up to 30 kilometres wide, that extends southeast from the north end of Vancouver Island for 180 kilometres. The belt is extensively faulted and occasionally intruded by masses of quartz diorite and granodiorite of the Early to Middle Jurassic Island Plutonic Suite.
The deposit is comprised of two beds of limestone separated by 30 to 45 metres of argillite that are overlain and underlain by volcanics consisting largely of amygdaloidal andesite and dacite. These rocks have been subjected to some low grade metamorphism by an intrusion just north of the deposit. The entire sequence strikes northeast and dips 30 to 60 degrees south. The upper (southern) bed is approximately 46 metres thick while the lower bed is approximately 61 metres thick.
The carbonate beds consists of massive, pearl grey to white, medium to coarse grained limestone (marble). Three samples comprised of chips taken at 4.6 metre intervals across accessible outcrops of the upper limestone bed assayed as follows in per cent (D.D. Campbell, 1973, page 7):
Sample K1 Length: 30m CaO: 55.06 CaCO3: 98.26 MgO: 0.30 Insol: 0.60 Al2O3: 0.36 Fe2O3: 0.34 Undetermined: 0.14
Sample K2 Length: 45m CaO: 54.92 CaCO3: 98.01 MgO: 0.20 Insol:1.01 Al2O3: 0.30 Fe2O3: 0.32 Undetermined: 0.16
Sample K3 Length: 60 m CaO: 54.83 CaCO3: 97.84 MgO: 0.30 Insol:1.20 Al2O3: 0.31 Fe2O3: 0.25 Undetermined:0.10
Probable (indicated) reserves are calculated at 7.6 million tonnes of limestone assuming a strike length of 180 metres for eachbed and a down dip extension of 150 metres (Industrial Mineral File -D.D. Campbell, 1973, pages 1, 8). The d
