Capsule Geology

The Germ occurrence is located approximately 2.5 kilometres northwest of the campsite where Paquette Creek enters Germansen Lake. The occurrence lies approximately 15 kilometres southwest of Germansen Landing.

This occurrence is hosted in the Upper Triassic Plughat Mountain Formation, part of the Middle Triassic to Lower Jurassic Takla Group. The Plughat Mountain Formation is a thick sequence of augite-bearing, mafic to intermediate(?), calc-alkaline to alkaline pyroclastic rocks, massive flows and lesser epiclastic rocks. In this area, the Plughat Mountain Formation is the upper volcanic sequence of the Takla Group. The lower, sediment-dominated sequence of rocks are part of the Middle to Upper Slate Creek Formation (Takla Group). To the northeast, the Takla Group is in fault contact (the Manson fault zone) with the Pennsylvanian to Permian Nina Creek Group. To the south, the Takla Group has been intruded by the Cretaceous Germansen Batholith, a multiphase granitic to granodiorite intrusion.

Mineralization consists of disseminated pyrite and chalcopyrite occurring within altered lapillistones of the Plughat Mountain Formation. The pyrite can make up to 5 per cent of the pale-grey silicified lapillistone. A grab sample analyzed 3.1 grams per tonne silver, 0.0208 per cent copper, 0.0220 per cent zinc and 0.0138 per cent lead (Assessment Report 20923). Rock sample 86226, taken in 1991, assayed 0.76 gram per tonne gold and 18.8 grams per tonne silver at the nearby PACQ showing (093N 086) (Assessment Report 21803).

Trace amounts of chalcopyrite are also found approximately 550 metres to the northeast of this showing. Pyrite also occurs with the chalcopyrite and these sulphides are found disseminated within altered volcanics.

Work History

In 1990, Rio Algom Exploration Inc. carried out a mapping program in search of the source of a regional magnetic high, which was determined to result from traces of magnetite in augite phyric flows. A geochemical survey was also completed on the GKO claim group; 11 rock samples and 14 silt samples were collected for assay.

In 1991, Golden Rule Resources Ltd. completed a reconnaissance geological program within the PACQ claim group. Three rock samples were collected and assayed.
