08/13/2020 (T Pettigrew) - DDH BL96-3 drilled through an intensely altered felsic to intermediate volcanic followed by a mixture of quartz diorite, granodiorite, and narrow ash tuff horizons all of which contained fine disseminated magnetite. The alteration assemblage associated with the mineralization includes chlorite-biotite-sericite. The mineralization consisted of disseminated to weak stringers of pyrrhotite-pyrite with minor chalcopyrite from 284.2-292.8 m, between two unaltered mafic units. The most heavily mineralized interval returned an averaged assay of 0.32% Cu and 7.1 gpt Ag over 2.6 m. The best assays from this drillhole returned 15.6 ppm Ag, 565 ppb Au, 0.56% Cu, and 0.077% Zn (Assessment report 52K14NE0046).
08/13/2020 (B Paterson) - Grade 1979: DDH HO-36 @ 172.1 ft assays 0.24% Cu/15.9 ft; Grade 1986: DDH HO-38 @ 359.8 ft assays 9579 ppm Zn /4.4 ft. Grade 1996: DDH BL96-3 @ 291.4 m assays 0.56% Cu and 565 ppb Au. DDH BL96-3 mineralization consists of disseminated to weak stringers of pyrrhotite-pyrite with minor chalcopyrite and is associated with chlorite-biotite-sericite alteration.
