Capsule Geology

The Tor occurrence is located on the east slope of the Pelly Creek valley just north of the divide between Pelly and Bower creeks, about 25 kilometres west of the community of Ware.

Regionally, the showing is hosted within a northwest striking fault-bound sequence of Cambrian to Ordovician rocks. These rocks have been divided into a lower sequence, the Lower Cambrian Atan Group, and an upper sequence, the Cambrian to Ordovician Kechika Group. The Atan Group, in the Toodoggone map area, is composed of three units. From oldest to youngest these are: quartzite with minor pebble conglomerate; impure quartzite, shale, local sandstone, conglomerate; and limestone, siltstone and dolomite. The Kechika Group is composed of phyllitic limestone, calcareous shale, limestone and phyllite. Immediately east of the Tor showing is a tabular, northwest striking Eocene dacite dike.

The Tor showing area is underlain by phyllite, limestone, shale, quartzite and silicified limestone of the Kechika Group. The showing consists of a silicified limestone unit with radiation readings 8 to 10 times background radioactivity. The unit contains zircon and pyrite, and the radioactivity is likely due to hafnium. A spectrographic analysis of rock from this unit showed no radium, uranium or thorium. However, the spectrographic analysis does indicate zircon (Assessment Report 218).

Work History

In 1958, Totem Minerals Inc. completed a program of geological mapping and a 101.5 line-kilometre ground radiometric survey on the area as the Tor 1-9 claims.
