Sep 25, 2016 (A Wilson) - The Emily Bay Deformation Zone (EBDZ) is located on the west side of Dog Lake in southern Riggs Township. The EBDZ is a 500 m wide, east-northeast trending zone of intense ductile shearing and weakly to strongly strained rocks. The EBDZ can be traced up to 4 km to the southwest of Dog Lake but cannot be traced to the eastern side of Dog Lake. The EBDZ is localized within massive to pillowed mafic metavolcanic rocks that are deformed to chlorite-calcite and chlorite-iron carbonate schists within several discrete ductile shear zones. These shear zones are NE-trending and vary in width from 1 m to greater than 30 m. A second set of narrow, brittle to ductile, NW-trending shear zones is observed in the vicinity of this showing.

Dec 07, 2005 (A Wilson) - The showing consists of a narrow quartz vein within granodiorite. The vein terminates against a diabase dike. The vein has been interpreted to be a tensional vein.
