Sep 24, 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.

Sep 24, 2016 (A Wilson) - The occurrence consists of a series of veins and lenses of quartz located in a sheared zone in altered mafic metavolcanic rocks near the contact with a feldspar porphyry sill.

Sep 24, 2016 (A Wilson) - Assays range from 0.01 oz./t Au over 30 inches to 24.00 oz./t Au over 60 inches. The quartz is described as sugary to coarsely crystalline and fractured. Some visible gold has been observed in the veins. The highest assay came from an area containing visible gold. The highest assay from the trenching done in 1986 returned 17.168 oz./t Au from a folded quartz vein. Calculated head grade from bulk sample #1 was 0.047 oz./t Au; and the head grade from bulk sample #2 was 0.028 oz./t Au.
