Aug 16, 2019 (Therese Pettigrew) - On the northeastern shore of Agutua Arm, gold mineralization occurs in a set of en echelon, quartz-arsenopyrite-pyrite-chalcopyrite veins up to 25 cm wide within a 1-3 m wide, east-trending, quartz-Fe carbonate-chlorite bearing zone. The carbonate-bearing rock grades into massive, actinolite-rich, mafic volcanics over a distance of less than 25 cm. The vein set can be traced for 25 m along strike. Veins, which typically overlap in a right-handed sense, dip vertically and consist of massive quartz with minor disseminated pyrite, arsenopyrite and chalcopyrite, and localized pods of massive arsenopyrite and chalcopyrite. Minor (less than 5%) chalcopyrite and pyrite occur intergrown with arsenopyrite in the massive pods. Gold values are highest within the arsenopyrite pods (up to 43 ppm, 1.3 oz/ton). Quartz veins that are relatively barren of sulphides and the silicified wall rock both returned insignificant gold values (25 to 80 ppb) (Piroshco et al., 1989). The highest values reported by Pyrotex were 2.54 ounces/ton over 0.3 m for Au, 18.8 ounces/ton over 1.2 m for Ag, and 2.50% Cu over 1.2 m (Breaks and Bartlett, 1991). Samples collected by Moss Resources in 1985 returned results of 0.67 oz/t Au (23.0 g/t Au), 0.71 oz/t Ag (24.3 g/t Ag), and 2360 ppm Cu (Assessment report 53B14NE0028).
