I just finished catching up on the posts from yesterday and this morning. I want to add my thanks to all "Posters" for one of the best discussions and comments over the past days, on this and possibly all Boards.

Tonnage: I backtracked to this Tonnage subject because the question of density did not come up, or else I missed it in the various calculations. From my metric past, I recall that 1 cubic meter of water (volume) with a density of 1.0 equals 1 metric tonne (weight). Rock density is approximately 2.7. Does it follow that a volume of 32 million CM's of rock at a density up to 2.7 would equal up to 86 million tonnes in weight?

Question: I am not an expert in interpreting the recently published results; so to what extent do they negate the January GNH Presentation, if at all?

Again, my thanks to all.......Deke
