I am not sure that Gabbros are actually all emplaced that deep. If they were then the gneiss would be conformable with the mineralization's emplacement horizon. Here the two planes are at 90 degrees. The gneiss would then have to have been formed by lateral pressure to make the ore plane normal to its bedding. My thinking is that when the gneiss was formed its erosional surface was established and the MS ore was emplaced upon that. Subsequently the Gabbro and other generations of magma overlayed the forming ore. Vents were gradually plugged by overlying melt, but before cooling was complete the vents created upward disseminating precipitation. Subsequent reburial and erosional exposure is a possibility after that. If you look at the NWI sections you will see that there is more than 120 metres of Gabbro and other mafic rock in some of the sections. The thin high grade section is not all that may make ore. I would guess that everything else that exceeds 1.2% combined Ni-Cu would be mined if the tonnage and high grade is sufficient to make averages above the Inco averages in a good nickel market. (1.2% Ni + other metals.) It would seem there is little to guess at to determine what those averages might be. The numbers may have to be crunched right down to the wire. We don't really know if we are losing or winning until a lot more data is in the pipeline. If we accept that 75 feet thick may make ore then we may have in this basinal type structure about 5 million tons of ore 1 km downplunge. It is mineable since the structure is thick and simple and sufficient grade, and importantly, will concentrate very well. Whether this is salable in this market is another issue. The satellites that may be found will enhance the potential considerably as they did at Raglan. This is the issue. Is this one of many? If it is, I may even give it some begrudging credit. Perhaps a site visit may be in order. EC<:-}
