His boardroom interview in late september gives a reasonable explanation , these guys took a while to work through all the old data and thats where the found the mistakes, the drill holes are broad and not very deep (60M) and their geology work up has the copper much deeper.

so they took a while work through the data and get the rigs in place

lets remember that these assays have been bought up by trained geo guys , they dont have to wait for a lab to tell them whats in them they can test that very quickly themselves, they know exactly whats in them the reason they need the lab is for independance

with a head grade of 4% during the mine life its not a surprise that there is more left over that they guys with steam engines missed

so he had rigs drilling closer together trying to intersect the arial surveys anoms, if he hits his targets then he might have something real big to announce
