A lot of commenters don't seem to have read the release. The diamond holes were bulk leached. that means the entire sample from each meter was leached. This gives a much closer estimate of the gold available, as it "sees" all the gold in the interval. So no splitting or introduced bias. That's why they say the RC is probably sampling low. 

"Samples were submitted to the laboratory as whole-metre intervals, where they werecrushed, pulverised and leached. "

It has the same repeat issues as alluvial gold. Notoriously difficult to sample. 

I'm guessing they won't try to get it past inferred, because the cost to get it to measured would be too high. It is not going to make or break the project, it's just icing, so they'll grade control it cheaply and put it through the plant early for easily recovered gold. Unless it turns out to be 5km long, then they might have to re-think.
