the only trouble with the statistics is that it is valid only after a certain number of holes and often in the hurly burly of the drill campaign and the fact the assays do not get back to you until 2-3weeks after drilling the actual hole - then by the time u start to get sig info - the program is 8-9tenths completed!!! - the industry calls it quality control but in reality it mainly happens after the fact - it is a area where what happened to EXU can happen anywhere by the way drilling campaigns and assay results turnarounds occur - rarely have i ever seen someone sit down half way through a campaign to point out any problems even if one was able to identify it at the time - it is actually a weakness in the way things are done!!
