Feb 16, 2011 (J Bongfelt) - 'Chalcopyrite, pyrite and pyrrhotite occur along fractures and between pillows in Early Precambrian basaltic flows.' (Kenora Historical File 52F/05NE00049/62, Green Bay - Document No. SMDR 000479)

Feb 16, 2011 (J Bongfelt) - 'North Shore Cu - trenching of the sulphide occurrence revealed Cpy-Py-Po mineralization between the fractures and pillow basalts. The two holes intersected mostly porphyritic granite and minor basalt; these holes may have been drilled down-dip a series of dykes. Only rusty, basaltic rubble was located by the author with traces of chalcopyrite located 500m east of Caviar Lake.' (Kenora AF 52F/05NE, JJ-1, Raoul, A. - 3.0 Economic Geology)

Nov 23, 2017 (Therese Pettigrew) - The mineralization can be broken down into two basic types: the mineralization in the pillowed basalts with copper values, and the mineralization in the basic intrusives with nickel and copper values. The most abundant sulphide in both cases is pyrrhotite, with minor amounts of pyrite and chalcopyrite. Pits 1 and 11 show the best nickel values, the sulphides being disseminated through a gabbroic rock. Some of the pillowed basalts have replacement pyrrhotite, chalcopyrite, and pyrite around the pillow edges, and also through the pillows (AFRI 52F05NE8181).
