I noticed as did some of you that I had made a big mistake in previous post. I understated the amount of revenue from Copper and Molydebdum - just a 1000X too small.
Thanks youngmoney for pointing out all the other ways that this mine can be improved.

Now assume that the metal recovering is only 86%
|
$ 4,814,119,866
|
|
|
|
|
It will take additional costs (processing) to extract the metals from the rock. I totally guessed at 10%

This gives an expected net revenue of

So under these assumptions, the NPV at 8% would go from $513 million to $2,221 million (much better than the $963 million stated earlier)
Also the NPV at 5% would go from $1,694 million to $4,122 million (previous post had it $2,334 million)
