Nov 21, 2014 (K R Kettles) - Intermediate and felsic volcanics underlie this showing, and strike roughly east-west and dip steeply north. A large trench has been put down across these rocks, exposing an iron formation containing much quartz, chlorite, and carbonate. A siliceous carbonate 'vein' is heavily mineralized (possibly a cherty bed) and contains disseminated sulphides along its margins.

Nov 21, 2014 (K R Kettles) - Within the iron formation a siliceous sulphide-rich zone is reported to carry gold over a 1.22 m width. The zone is heavily mineralized with gold, silver, nickel (Riley), minor pyrite, chalcopyrite, and sphalerite. Disseminated sulphides occur in the units on either side of this zone. In 1963 chip samples were assayed as follows : 0.06 oz/t Au, 2.76 oz/t Ag, 1.25% Cu over 1.22 m, also grab samples assayed: BEST: 0.07 oz/t Au, 7.64 oz/t Ag, 2.10% Cu, 0.08% NI. 2009 Trench and Grab samples taken. Trench assays: highest 0.414 ppm over 50 cm Au. Grab: highest sample 10.7 ppm Au and 2510 ppm Cu
Nov 21, 2014 (S Gosselin) - Heavy chalcopyrite and pyrite mineralization is exposed in a silicified carbonate vein approximately 1 foot thick. Finely disseminated chalcopyrite, pyrite, and minor sphalerite are present in the contiguous chloritic rock. The vein does not appear to extend along strike.
Oct 14, 2020 (Therese Pettigrew) - Samples collected by Halo in 2009 returned up to 2510 ppm Cu and 0.348 ppm Au (Assessment report 20000006127).
Dec 07, 2005 (K R Kettles) - The gold bearing mineralized zone in the iron formation is rich in quartz and carbonate. Chlorite is present.
