Gold show ;I used to watch that show about gold miners . It was on just a few years ago . Anyways, one miner had an notion that they were letting the fine, fine gold get by due to their setup. Long story short, the fine gold was getting by and they ended up increasing production by 10 to 20% . Needless to say i have bought PHD in a pretty big way . If these guys were hauling in 6-10 oz per tonn i really don't think they were too concerned about a little grainy gold getting threw . Do you ??
