Mineralization Comments

Jul 26, 2019 (Therese Pettigrew) - Sample Q6051 collected by Sherritt Gordon staff in 1981 returned an assay of 1.45% Cu. Sample Q6035 returned an assay of 1.17% Cu. Sample Q6045 returned an assay of 0.07 oz/t Au (2.18 g/t Au) and 0.8 oz/t Ag (24.88 g/t Ag) (Assessment report 52N07SE0043). Falconbridge’s DDH 3 returned up to 0.23% Cu, 0.205% Zn, 0.13 oz/t Ag from a brecciated, chloritized and carbonatized andesite with quartz-calcite veins, 3% pyrrhotite and 2% chalcopyrite (Assessment report 20000005547). Sample 79240 collected in 2012 returned 0.322 ppm Au from a silicified andesite that was weakly carbonate altered and contained 7-8% pyrite in stringers and trace chalcopyrite and pyrrhotite disseminated throughout. 10% magnetite blebs were associated with sulphides.
