Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The only well documented occurrence of its type on Mount Jamie's ground, this 'vein' is a near-vertical mineralized shear zone that strikes S80 deg. E. This shear zone occurs in the contact area between felsic lava and biotitic intermediate pyroclastic rock to the north, and a very hornblende-rich (73% hornblende) mafic 'tuff' to the south. This zone has been traced in outcrop and trenches for 45 m. It carries pyrite and sphalerite (in places as streaks 1 cm wide), and minor amounts of sugary quartz. A similar shear has reported to carry arsenopyrite (Thomson, 1947) and unusually light-green chlorite was noted in this 'N. 3 vein'. DEPOSIT DESCRIPTION: This roughly east-west striking mineralized shear zone (at least 45 m long) has been reported to carry gold. The shear zone reportedly is 0.6 to 1.2 m wide (Honsberger 1936). GEOCHEMICAL DATA: Possible potassium enrichment and sodium depletion.

Dec 07, 2005 (K R Kettles) - This roughly east-west striking mineralized shear zone (at least 45 m long) has been reported to carry gold. The shear zone reportedly is 0.6 to 1.2 m wide (Honsberger 1936). Grab samples of 'massive sulphide' assayed as high as 0.25 oz/ton (8.571 g/tonne) Au.
Oct 30, 2020 (Therese Pettigrew) - DDH JF-85-31 returned up to 0.13 oz/t Au over 1 foot from 109.5-110.5’ from a quartz veinlet in a metasediment. DDH JF-85-32 returned up to 0.23 oz/t Au over 1 foot from 108.5-109.5’ from a quartz veinlet in a metasediment with pyrite, pyrrhotite, chalcopyrite, galena, and a speck of visible gold (Assessment report 20000004954).
Dec 07, 2005 (K R Kettles) - The intermediate pyroclastic rock is very biotitic. A pale green chlorite (or possibly fuchsite) occurs in the shear zone.
