Jan 30, 2015 (Therese Pettigrew) - The property is predominantly underlain by the Dome Stock, with the SE margin underlain by Balmer mafic volcanic rocks. The Dome Stock dominantly comprises porphyritic granodiorite which is texturally massive. Minor areas of the stock are quartz monzonite to granite in composition. The granodiorite is grey to pinkish grey and coarse-grained. In areas of intense shearing and adjacent to quartz veins and dykes, the granodiorite is commonly altered to a dark grey as a result of chloritization and silicification. The Balmer Assemblage is composed of mafic volcanic rocks, which are observed in the southeastern-most portion of the Buffalo Extension zone. There are two greenschist-facies mafic volcanic units present, a tholeiitic-komatiitic meta-volcanic unit and a sequence of calc-alkalic meta-volcanic rocks (2014 NI 43-101 report).

Jan 30, 2015 (Therese Pettigrew) - The Buffalo Extension Zone is located in the southern part of the East My-Ritt claim block and primarily comprises granodiorite of the Dome Stock. In the southeastern most corner of the claim block, mafic volcanic rocks of the Balmer Assemblage are present. The mineralization is contained in two separate groups in the Buffalo Extension Zone: disseminated throughout the granodiorite, and within quartz-tourmaline veins which are locally common in the granodiorite. Mineralization is restricted to the granodiorite, and is not observed in the Balmer mafic volcanic rocks (2014 NI 43-101 report). Assays from the Buffalo Extension range from 0.5 to 16.85 g/t Au, including the following results: DDH MM1016: 144.7-146.5 m: 15.7 g/t (visible gold) DDH MM1017: 155.5-156.5 m: 7.82 g/t (visible gold) DDH MM1146: 114.0-157.3 m: 0.685 g/t DDH MM1147: 178.5-202.5 m: 0.50 g/t DDH MM1148: 114.0-147.0 m: 2.34 g/t; 220.3-237.0 m: 0.68 g/t; 249.0-268.5 m: 1.35 g/t DDH MM1149: 96.0-102.0 m: 0.99 g/t; 149.8-156.0 m: 2.43 g/t DDH MM1150: 187.5-193.5 m: 1.77 g/t DDH MM1152: 237.0-249.0 m: 7.25 g/t incl. 241.2-246.0 m: 16.85 g/t DDH MM1154: 222.0-223.5 m: 8.70 g/t (Mega Precious Metals Sept 9, 2011 press release)
