Large diameter drillingA slow day while we await news...
I haven't seen much here about the details and reasoning behind the abandonment of the large diameter drilling. So I thought I'd post this here - quote below taken from a post at ceo.ca. - apologies if I haven't followed the appropriate cross forum protocols, but I though this was interesting and wanted to allow those here some insight into Novo's reasoning, rather than just leaving it as a conspiracy theory.
Would a really big shop-vac have helped?

"Someone's recollection of what DL said at their annual meeting as to what went wrong with the 17.5 drilling (hotcopper poster "energytsars"): There was some discussion about getting JORC resources calculated and reported and the failure of the wide diameter drilling as a sampling system. DL and others said the problem was that the 17.5" drills reduced everything to chips and the nuggety gold was falling to the bottom of the shaft and no amount of air compressors was going to lift it all up in a manner that allowed accurate reporting of the depth of any set of chips."
