There would not be a diamond drill anywhere that did not have its share of speculators. The drillers themselves, wives, GFs , mates and if they are being billeted at the local pub or caravan park then its on for young and old. The results though at this stage are all visual and subject to interpretation. The drill core when taken out should be done with only the Geos on hand, the cores should then been sent off to a lab for evaluation. Some cores are cut on site giving a better visual prognosis , but experienced drillers will know if something is about from dust and chip samples coming from the hole during the drilling process. All this is out of the Companies control, especially with sats and mobiles phones in everyones pocket.
