Abstract
The principal gold mineralization on the GOG-CGK property in Verneuil, Quebec is completely hosted within the Toussaint Shear Zone (TZS). The shear zone is parallel to sub-parallel to lithologic units and has a sharp footwall contact with diorite and a more gradational contact with gabbro hanging wall. The majority of the shear zone is hosted within an intermediate volcanogenic/crystal tuff unit but also extends into the gabbro. The maximum width of the shear zone is 27 metres.
Four mineralized horizons occur in the TZS of which two are sub-economic having values between 0.4 and 3 ppm Au. All of these horizons are parallel/sub-parallel to the lithological contacts. The two 'low gold horizons' outline the hanging- and footwall limits of the shear zone.
