Can the 8 to 10 gm/tonne in Note B be compared to the gm meter values listed above in determining what an excellent underground grade is or are they completely different units of measure used for measuring different things and so using one to compare the other misleads people who know no better and in fact GGGThe prbly doesnt know the difference and neither do you. Being from Missoura where there are no gold mines. Hillbilly.
