Dec 07, 2005 (A Wilson) - The Hook Lake Shear is characterized by chlorite schist and chlorite breccia. Quartz veining, commonly mineralized with minor chalcopyrite is spatially associated with this structure. It can be traced from Speight Lake to Hook Lake. The shear bends from a trned of 100 to 118 in the east to bout 90 in the west.
