Thanks Scott!
I looked at the raw data available on the GNH web site, and indeed there were a lot more 1m samples with VG and high grade beyond 300 meters.
Specifically, from 333 to 339 meters (as noted in the press release) wich containted large amount of Visible Gold in the core.
Of course 335 to 336 meters had VG and a relatively low grade, so VG is no guanratee of a high Au concentration in that section.
333 334 19350 1.87 10800 1 334.87 VG 10800
334 335 19351 1.755 26400 26400
335 336 19352 1.605 817 1 335.2 VG 817
336 337 19353 1.845 3990 1 336.5 VG 3990
337 338 19354 2.27 1800 1 337.11 VG 1800
338 339 19355 1.93 17000 1 338 VG 17000
Of course, a sample size of n=1 doesn't make for a good statistical sample. :-)
