Just talking to a driller a bit ago, they average 66m per 24 hour shift through pretty well any type of rock. This is with an NQ, around 2 1/4 inch core. I heard Lori say 4 inch core, maybe at the Calgary Meeting, but this was later on in the drilling where this bigger core size was used, to my knowledge. The bigger the core diameter, the better chances of getting better representaion of grades.The quartz does slow down drilling below this average, but with us it should have no effect at all, because our veins are narrow, except if we hit one of those "blow out" zones which is referred to in the recent Captol 88 release of our Chance F, where it states that quartz flooded some of the faults on Chance F. But, if we would have hit one of those areas, we should have heard about it in the drill releases, right? Another thing to slow down drilling is, if the rock is fractured a lot, causing plugging . But, Lori said the drilling went extremely well, so I don,t see where that could have been a factor in slowing down drilling as well.
IMO
