NMI
Name T, CAP, SOUTH CAPOOSE LAKE Mining Division Omineca
BCGS Map 093F024
Status Showing NTS Map 093F06W

Longitude 125º 16' 52'' Northing 5906928

Capsule Geology

The T occurrence is located west of Capoose Creek and approximately 2.5 kilometres south east of the south west end of Capoose Lake.

The region in which the T showing occurs is within the Intermontane Belt, underlain dominantly by Lower to Middle Jurassic volcanic and sedimentary rocks of the Hazelton Group. These assemblages are overlain by the Upper Cretaceous to Lower Tertiary Ootsa Lake Group and Miocene plateau basalt. Intruding Lower Jurassic rocks of the Hazelton Group in the northeastern part of the map sheet is a belt of granodiorite, diorite, and quartz diorite plutons of the Lower Jurassic Topley intrusive suite. Felsic plutons of probable Cretaceous age intrude both Lower and Middle Jurassic Hazelton strata.

The showing is underlain by a Lower Cretaceous (Upper Jurassic?) pluton, known informally as the Capoose Lake batholith. Mineralization consists of molybdenite in quartz veinlets and as disseminations in granodiorite.

Work History

In 1970, Rio Tinto Canadian Exploration Ltd. completed a soil sampling program, geological mapping and a 20.8 line-kilometre ground magnetic survey and 46.8 line-kilometres induced polarization survey on the area as the Cap and T claim groups. The following year, an induced polarization survey was completed on the Cap and T claim groups.
