RE:RE:RE:RE:EV/oz productionWith recoveris of >95% I can't see any real reason for Pretium to consider sorting as a necessity. If this process is applicable it may be useful to reduce the volume of rock being ground and there could be some cost reduction at the milling end but the area where the costs would be significantly reduced are at the stopes where you are dealing with the question as to whether to mine this low grade block or to pass.
From what I see in the pictures where this technology shines is at the secondary crushing stage and there may be some application but PVG will already have spent most of the money getting the rock into the mill.
If there was a bottleneck in the mill I can see where this could really help but at this stageI think that the effort being made to improve grade control underground will pay larger dividends.
This is an interesting technology and I appreciate the post.
