I agree Polylabel, the estimate is likely light. I was only quoting what was said on BNN (from what was posted here earlier). I think the drills have not defined the true size of DE1 yet, let alone 2/3 etc. I think the estimates are based on a read of the mags compared to what the drills have said to date in order to try to determine the shape/depth of DE1. Personally I think they are conservative and this thing is bigger and deeper than what has been thrown around so far.

I think we all have to keep in mind that rarely are these things smooth sided intrusions, either round or oval. They will have multiple dips, cracks, crevaces side bars and whatever. So when the rubber hits the road (or in this case the shovel hits the rock), there will be more tonnage than the estimates say.

JMHO
