All good, wanted to be sure I didn't understand it incorrect and you were keen on something I wans't. It is also a fairly large difference in the recovery rate. 63% could be low or high also, the range is large and I don't know what samples they all tested and things of that nature. But as you noted the average grade seems to be higher than historical. Either way seems with the recovery rate, a small guess at the reserve size and using some of that info hoghead was looking at in regards to the acid cost, it would be possible to get some rough figures on what VD could potentially Yield.
