Great read about EMH, page-19

Miro , May I then suggest you move on from the past , the minute you lose is the one you never get back . We have some extremely compelling numbers , which , I am sure are a lot more accurate than the back of envelope ones back in the scoping study two years ago . I recently spoke to Lepidico and questioned some of their figures , even currently I am not personally convinced that they are still reporting costs as accurately as you may think , their $350 per tonne ( " US$350/t was used for the PFS, based on a quoted supplier price, inclusive of feed preparation and shipment costs." )  is only based on one mine and is left over of existing mining operations it does not have the cost of any new mining to produce ore  . In effect they are left over tailings that have had the mining costs absorbed by other operations of the said company . Who then knows where the cost for them will be if they were to get access to new ore mined . Maybe that's why EMH has chosen the process route they have .
