You are wrong. For that hole, 169.72 is the highest interval and it’s in saprolite, not fresh.
I assume you are looking at 216.16 in TERC-007 to justify your argument? For that interval I’d expect to see a discrete ‘something’ carrying a visible gold grain or two. ‘Something’ could be a discrete shear within the dolerite or a quartz vein related to the mineralisation event. I doubt that interval is geologically identical to sub 10gt dolerite and therefore not representative of the whole fresh domain.
