I looked at the metal prices and calculated using the same amount of material shown in the PFS with both prices. It's not just the price of metals it is the ratio of the different metals. That's why the price of molybdenum suddenly became important.
In the PFS there were 11.3 million pounds of molybdenum produced per year. So in the PFS that amounted to $372.9 million. In the FS it amounts to $165,432,000. That's a revenue loss of $207,468,000. (On top of that we don't have as much molybdenum in the FS, and I didn't even calculate that.)
Even if you calculate the value of all the other metals that increases in value with the FS, we are still short $51 million a year because of the huge hit we took on moly, and the weight it has on our numbers.
In the PFS Molybdenum represented 50% of our salable product.
