Interesting calculation!! But what you have measured is a potential geological inventory. You should be careful not interpret these numbers as potential mineable reserves (ie don't use those tonnes to calculated potential future revenues)!! All pits have economic depths, and a maximum slope to the pit walls. The mineable reserves that the feasibility study comes up with will likely be much less than that. What sort of geological resources/mineable reserve factors where experienced at Diavik, Jwaneng, or elsewhere?

I knew we were in the ballpark Jesse..Re Jackleg's comment that we should not imply a resource tonnage .. I think a number of companies will use these types of calculations with some refinements for conical shapes determined by delination drilling.eg the SUF M1 pipe. The bulk sample results will provide the cts and $$ per tonne and the estimated values for the pipe are determined. Of note the M1 pipe is estimated at 600,000 tonnes graded at 341 ct/100tn and $142 ct. If we end up with 35 ct /100tn at $60 ct on K14... 75,000,000.3560 = 1.575 billion. Even if we are 30% out in our estimate..K14 ON IT"S OWN looks to have economic potential to say the least. Regards DJ
