Interesting stuff hey folks? It was easy for sceptics to kick James Darcel around as "he's no Geo", but how do you refute a guy like G.A. Harron?
Can't wait until those truth machines (drill rigs) and Micon get together and produce a revealing story for ISM!
"At its fullest development, massive sulphide mineralization up to 1.5 m thick (5% Ni) is overlain by up to 7m of net-textured sulphides (2-4% Ni), followed by up to 13 m of disseminated sulphides containing 0.3- 0.9% Ni (Green and Naldrett, 1981). PGE (Os, Ir, Ru, Rh, Pt, Pd) concentrations in the massive sulphide mineralization are in the order of 133-3220 ppb (Appendix 1). In the disseminated and net-textured mineralization, PGE (Os, Ir, Ru, Rh, Pt, Pd) concentrations range from 963 to 1956 ppb (Appendix 1). Sulphide minerals (pyrrhotite and pyrite) comprise about 60% of the volume in the net-textured sulphide mineralization. Overall dimensions of the net-textured and disseminated sulphide mineralization are unknown, as drill logs are not available for perusal. However, as illustrated in figures 8, 9, and 10 all three zones of mineralization are open to depth."
"The main Langmuir # 2 deposit also strikes northeast, dips steeply southeast and is approximately 400 m long and extends deeper than about 400 m. The economic mineralization occurs at the contact of overlying komatiitic rocks, and a footwall assemblage of felsic to intermediate volcanic rocks (Figure 11). In places sulphidic chert-magnetite iron formation forms the footwall. Massive sulphide mineralization up to 2.5 m thick is overlain by up to 12 m of net-textured mineralization followed by up to 28 m of disseminated sulphide mineralization. Mineralogy of the ore is an assemblage of pyrrhotite, pyrite, pentlandite, chalcopyrite, chromite and magnetite. Some millerite occurs within highly sheared ultramafic rocks. Previous operators milled 1,133,750 tonnes grading 1.45% Ni. Some assay data pertaining to the deposit is presented in Figure 12, and additional assay data from Green (1978) is presented on Appendix 1."
