Thank-you for your post Jack. I greatly appreciate your perspective, posts, and the info therein. Would that be $30.00 to $40.00 per tonne Canadian or US for the underground part estimate? Others have mentioned that much of the ore would lie in a permafrost section. How would that effect the operation in terms of thawing and freezing-refreezing crushing? I am also curious about the use of diesel powered equipment underground. I suppose that would neccessitate some powered ventilation. I suppose that propane powered equipment in confined spaces might create an explosion hazard. Bring on the fuel cells. If the Kimberlite is soft enough to crumble in your hand as some have suggested, could some type of large diameter boring device be used to bore and crush at the same time? Again, I suppose that moisture content and temperature would be a factor. I am not expecting the definitive final answer, just your perspective and thoughts based upon your experience.
