Oct 11, 2017 (R Tuomi) - Best assay: 16,373 ppm Cu from surface. Best assays from the 1984 program returned 1.64% Cu.
Oct 11, 2017 (Therese Pettigrew) - Trenches at Bruce Lake were described as having disseminated to streaky pyrrhotite (10%), chalcopyrite (5%), pyrite (5%), and bornite (1%) occurring within light grey to green, silicified, variably calcareous mafic to intermediate metavolcanic rocks. Interbeds of pyritic (5%) ankerite-sericite schist with local specularite and tourmaline were observed. Reconnaissance sampling yielded several low gold-silver and strong copper anomalies (to 34 ppb Au, 1.6 ppm Ag, and 16,373 ppm Cu) (AFRI 52F05SE0068).
