Capsule Geology

The Tak (Scree) occurrence is located at an elevation of approximately 1900 metres on the northeast end of the informally named Goat Ridge, approximately 18 kilometres west of the northwest end of Germansen Lake.

The area lies at the contact between volcanic rocks of the Lower Jurassic Twin Creek Formation of the Middle Triassic-Lower Jurassic Takla Group, and probably Lower Jurassic dioritic and monzodioritic phases of the Upper Triassic to Lower Cretaceous Hogem Intrusive Complex. The contact is a complex hybrid zone of intrusive, subvolcanic, and volcanic rocks. Volcanic textures are difficult to discern due to contact metamorphism; many volcanic fragments occur as ghost outlines and clots of epidote suggesting resorption and metasomatic alteration with intrusive phases.

Locally, an augite porphyry hosts disseminated pyrite and chalcopyrite with malachite staining.

In 1990, a sample (10243) from the Scree zone yielded 0.25 gram per tonne gold, 6.2 grams per tonne silver and 0.659 per cent copper, whereas samples (10183 and 10193) of similarly mineralized augite porphyry and crystal tuff, taken east and northeast of the Scree zone, yielded 0.511 and 1.205 per cent copper, 18.2 and 11.4 grams per tonne silver with 0.347 and 1.450 grams per tonne gold, respectively (Assessment Report 20838).

In 1991, a grab sample (P91NL008) from the Scree zone yielded 0.934 per cent copper, 24.1 grams per tonne silver and 0.166 gram per tonne gold (Assessment Report 22192).

Work History

The area has been explored in conjunction with the nearby Tak (MINFILE 093N 067) occurrence and a complete exploration history can be found there.
