Jun 16, 2020 (Therese Pettigrew) - A large number of porphyry dykes cross the property and are, almost without exception, carbonatized, pyritized and contain quartz, quartz-carbonate and/or quartz tourmaline veins. Veining and alteration are strongest in the vicinity of Troutfly Lake and tend to die out towards the west, although the intensity may vary along any particular dyke. The veins tend to cross-cut dykes approximately 025° and 160°, but may be stringer-type in multiple directions. At least three ages of veining are apparent: an early set of qu&rtz veins generally sub-parallel to foliation or cross-cutting at high angles; quartz tourmaline veins; and later quartz-carbonate-sulphide veins. Sulphides occur in the altered dykes as heavy disseminations (Assessment report 20000005237).

Jun 16, 2020 (Therese Pettigrew) - A sample from a trondhjemite dyke located at 30+00W/3+75N returned the highest values: 10 ppb gold and 86.5 ppm silver. The high silver value is due to galena in vein material. A porphyry dyke traced from 32+00W/0+50N to 18+00W/3+75N may be twenty meters wide and is the most altered dyke observed. Erratic values ran up to 50 ppb gold, 3.7 ppm silver, and 900 ppm tungsten (Assessment report 20000005237).
