Vaughn, Never IF NVB came on line and IF there was sufficient quantities (>150 mT) within 100-150m of surface and IF the prices recovered at least 50-65% from their present level......... Sorry can't even see it then. The economics are complex but I know for a fact that the NVB has far more of SVB type mineralization that is not even considered in any resource calculations. SO if it is not feasible there it will never be feasible at SVB......IMO. There are a few things to consider in terms of Ni and Cu. The ratio is an important indicator of several things...I never completely knew of all of them. I does vary within a system usually from 1:1 (Ni:Cu) to 1.8:1 I would assume that the Ni is therefore max'd out and these numbers represent the last sulfide in the system In the context that footwall mineralization (last precipitation) is always enriched in Cu. Represents the fluid/solid stability field of Cpy, or something along those lines. The rationale for the Ni or Ni tenor may be related to the fact that disseminated ores have a higher Ni content than massive ores, cet. par.. Thus the search for massive sulfide is a search for tonnage rather than grade. It is a case of two temporally separate magmatic events. One (disseminated) does not have to include the other (massive)! Minor massive sulfide accumulations as part of the primary sulfide event are common but rarely if ever economic. I still do not have a clear 3-D image of the geometry of the msv sulfides. I did try a while ago, but perhaps with the new info I may be more successful. Regards 1King
