Capsule Geology

The Torse (L.1279-1283) occurrence is located on a hill east of Snug Basin, a few hundred metres east of the creek mouth.

The area is underlain by a north trending band of Upper Triassic Vancouver Group, Quatsino Formation limestone in contact to the east with Lower Jurassic volcanics of the Bonanza Group. The strata is intruded by diorite and granodiorite of the Early to Middle Jurassic Island Intrusions.

At various elevations, along the contacts of crystalline limestone and hornblendic volcanic rock, there occurs several outcrops of pyrrhotite, iron pyrites and chalcopyrite. The deposits generally occur in a gangue made up of epidote-garnet, altered limestone and brecciated volcanic rock. The occurrences are lenticular in structure, with irregular boundaries, and vary considerably in extent.

There is reported to be at least two promising deposits, one at 170 metres elevation and the other at 410 metres elevation. These deposits have been exposed by open cuts and/or by shafts and tunnels. An average sample from the deposit found at the higher elevation, taken across 3.7 metres, assayed 0.8 per cent copper, 13.71 grams per tonne silver and a trace of gold (Minister of Mines Annual Report 1916).

In 2007 through 2012, Nahminto Resources completed a program of prospecting, geological mapping, geochemical sampling, a ground magnetometer survey and airborne geophysical surveys on the area as the TJM claims, apart of the Nahmint property.
