Sep 23, 2016 (A Wilson) - The Dog Lake Deformation Zone (DLDZ) is located in the central part of Riggs and West townships, where it is defined by a 1.5 to 2.0 km wide southeast-trending zone of moderately to strongly strained rocks. The DLDZ is characterized by both ductile and brittle-ductile shear zones which occur in two dominant orientations 90-100 degrees and 110-120 degrees. Shear zones at these orientations within the mafic to intermediate metavolcanic rocks are defined by 1 to 50 m of chlorite-calcite and, rarely, chlorite-iron carbonate schists. Shear zones within feldspar and quartz-feldspar-porphyry intrusions are defined by quartz-sericite schist. Narrow NE and NW trending brittle and brittle-ductile shear zones are also observed with the DLDZ.

Dec 07, 2005 (A Wilson) - The showing consists of veins and lenses of sugary quartz within a sheared quartz-feldspar porphyry.
