Capsule Geology
The Nootka Marble deposit of re-crystallized limestone is located at the head of Hisnet Inlet, a north westward extension of Tlupana Inlet.
This occurrence is situated near the southeast end of a band of limestone of the Upper Triassic Quatsino Formation (Vancouver Group), extending
northwest from Tlupana Inlet to Tahsis Inlet. The band continues for more than 1600 metres eastward from Hisnet Inlet. The limestone in this
vicinity is more than 300 metres thick. Bedding strikes 060 to 080 degrees. A 3.5-kilometre wide stock of granodiorite of the Jurassic Island Intrusions
intrudes the limestone a kilometre southeast of the quarry site.
The deposit is comprised of medium to coarse grained, white to light grey limestone (marble), occasionally containing some dolomitic bands. At the
quarry site the limestone is intruded by basaltic dikes that make up to 55 per cent of the rock. Two samples of limestone from the quarry averaged
54.18% CaO, 0.78% MgO, 0.68% in-solubles, 0.028% Al2O3, 0.095% Fe2O3 and 0.013% sulphur (Canada Bureau of Mines Report 452, pages 167,
168, Samples 1424, 1425).
Another band of marbleized limestone, located immediately south of the deposit, was identified in 2011. It is 5 to 50 metres thick and exposed over
500 metres with a gentle north east dip. The average of 5 samples yielded 53.6 per cent CaO, 42.7 per cent LOI and 96.3 CaCO3 (Assessment Report
32853).
The deposit was originally quarried for marble by Nootka Quarries Ltd. between 1908 and 1909, but no production figures are available. Matrix
Marble & Stone produce Tlupana Blue and Vancouver Island White in the area. See also Tahsis Inlet (092E 070).
In 2010 and 2011, Rock-Con Resources completed programs of remote sensing (spectral analysis and synthetic aperture radar), geological mapping
and rock and silt sampling on the area immediately to the south east as the Tahsis property.
