The Jake South occurrence is located approximately 14 kilometres northwest of Motase Peak and about 154 kilometres north of the town of Smithers.
The occurrence has regional and local geology similar to that of the Jake North occurrence (094D 061) located 8.5 kilometres north.
The local geology consists of interbedded mudstones, siltstones, sandstones, wackes and minor conglomerates of the Upper Jurassic to Lower Cretaceous Bowser Lake Group. These sediments are intruded by stocks of biotite-plagioclase porphyry and biotite-hornblende-plagioclase porphyry. The intrusions are possibly related to and contemporaneous with either the Eocene Kastberg Intrusions or the Late Cretaceous Bulkley Plutonic Suite (Assessment Report 16838).
Mineralization is divisible into two stages: a late hypogene stage, and an early hypogene stage. The early hypogene stage is characterized by white quartz veins in hornfelsed sediments. The veins are typically up to 1 centimetre thick and contain abundant pyrite with minor pyrrhotite and chalcopyrite. One sample assayed 0.128 per cent copper and 1.3 grams per tonne silver (Assessment Report 16838).
The late hypogene stage is characterized by grey quartz veins in hornfelsed sediments. The veins, typically 10 centimetres thick, may be vuggy or contain seams of sulphides. The veins are composed of wallrock fragments, arsenopyrite, pyrite, sphalerite, minor galena, chalcopyrite, greenockite and malachite. The veins occur in a zone of sheared and carbonate-altered rock. Late ankerite and calcite locally fill the vugs. In 1987, one of the best samples assayed 3.7 grams per tonne gold, 1.24 per cent lead, 2.5 per cent zinc and 25.2 grams per tonne silver (Assessment Report 16838).
In 1987, QPX Minerals Inc. conducted contour soil sampling (1147) with lesser stream sediment (178) and heavy mineral (9) sampling on their Jake claim group which covers the Jake North occurrence (094D 061) in the north, and the Jake South occurrence (094D 119) in the south. The occurrences are about 8.5 kilometres apart. Refer to Jake North for a detailed work history of the area.
