Aug 13, 2020 (Therese Pettigrew) - Grab samples collected in 1984 from a pod of massive sulphide containing base metals graded 0.25% Cu, 2.68% Zn and 0.05 g/tonne Au over 1 meter. High-grade grab samples gave values up to 8.38% Zn, 16.0 g/tonne Ag and 0.05 g/tonne Au. The occurrence was located at a mafic volcanic-sedimentary contact (Assessment report 52N08SE0004).
Aug 13, 2020 (Bill Paterson) - Zn/Cu showing is associated with a magnetite iron formation within fine-grained metasediments. EM conductor was explained in drill intersections containing up to 40% pyrite - no significant assays were obtained.
