07/26/2019 (T Pettigrew) - There are two small weak to moderate shear zones within the Ferraro Zone. Both of the shear zones are only present within the mafic metavolcanics and seem to dissipate within the gabbros. The northern shear zone has a strike of 102 degrees and a dip of 85 degrees dipping south. Towards the western edge of the trench the shear direction shifts to an 080 degree strike, and vertical dip. The southern shear zone has a strike of 098 degrees, and a dip of 75 degrees dipping south, and seems to be an extension of the quartz vein which sampled at 292 g/t Au. There are also three distinct fracture directions, mostly visible within the mafic metavolcanics, but also present in the gabbros. The three fracture directions are 001 degrees dipping 80 degrees to the east, 080 degrees dipping 82 to the south and 340 degrees dipping 77degrees to the east, the second of which seems to parallel some of the shear, and quartz veining.

07/26/2019 (T Pettigrew) - The Ferraro Zone trenched area is 35 m long. The zone strikes east-west and is characterized by a thin mineralized quartz vein. The gold mineralization is confined to smoky grey, sulphidized, weakly fractured quartz veins, and the immediate sulphidized wallrock. The quartz vein with strong gold mineralization is approximately 20 m in length, and less than 15 cm in width. The quartz vein crosses the mafic metavolcanic unit, and the gabbro unit. The sulphides mineralization consists of disseminated pyrite, pyrrhotite, and chalcopyrite both within the quartz vein, and the surrounding wallrock. There are several specs of visible gold in the vein, mostly localized to a section of the vein 25 cm long A sample from the quartz-tourmaline vein assayed 292 g/t Au with 35.4 g/t Ag and 3.24% Cu. Channel sample highlights include 37.18 g/t Au over 0.80 m including 196 g/t Au over 0.15 m (Assessment file 20000006338).
