Feb 06, 2007 (Mark Puumala) - Sage and Breaks (1982) report that this deposit consists of several lenticular bodies of peridotite and gabbro hosted within amphibolite (likely mafic metavolcanics). Patterson (1980) has further classified the intrusions as consisting of gabbro (80%), peridotite (10%), dunite (5%) and olivine gabbro (5%). The largest intrusion is reported by Sage and Breaks (1982) to have dimensions of approximately 600 m by 300 m, and is approximately 240 m thick. The reported grade of this intrusion is 0.45% Cu and 0.12% Ni (Sage and Breaks 1982). Mineralization is reported by Patterson (1980) to consist of primary disseminated sulphide, metamorphosed disseminated sulphide, breccia sulphides and oxidized sulphides. The sulphide content of the intrusion locally exceeds 5 %, with the mineralization consisting primarily of chalcopyrite and pyrrhotite with exsolved pentlandite. The sulphides are also indicated to be intergrown with magnetite and ilmentie (Patterson 1980). Breccia sulphides occur as narrow zones of sulphide containing angular rock fragments. Oxidized sulphides occur in close proximity to faults and near the top of the intrusions. Mason et al. 2001 report that the Kapkichi J deposit hosts reserves totaling 37 million tonnes grading 0.40% Cu and 0.12% Ni.
Jan 20, 2022 (Therese Pettigrew) - Sulphides in order of abundance are pyrrhotite, chalcopyrite, cubanite and pentlandite, magnetite, and a little pyrite. A lens approximately 610 m long x 305 m wide and up to 244 m thick is uniformly mineralized with grades of about 0.45% Cu and 0.129% Ni (Thunder Bay RGP files).
