RE: Missing GoldIt would be interesting to find out how much high grade dike they have been running through the mill last quarter.
While the dike rock can be multi oz ore, it has always been a problem for the roaster and recovery isn't very good.
First the dike isn't carbon based like the other ore and the gold is locked in silica. Not sure if there is an economical solution.
I find this subject pretty interesting and found several years back that Barrick had the same problem at a silver mine they own. This sight explains it better than I can

Could very well be what they are dealing with, again, just my opinion.
