Last point first ...there IS no relevant data ! There is no...

Last point first ...there IS no relevant data !
There is no resource yet let alone a reserve and no details on mining costs !
Sorry Dolce but you can GUESS at figures but not even the experts at this stage
(and , no offense , i doubt you are ) can pinpoint figures the way you have and say that's the number !!
Or assume San Felipe geology and ore distribution are the same .

But yeah , I looked at San Felipe back when you mentioned ..(.no intention to look again)....in some detail at the time !
But here's the thing ....
Another marginal project that never got off the ground yet you are taking it as the template for Ospura !??
Why ?
What does that imply about Ospura !
Never got off the ground ...wasn't even worth doing a DFS on !
All the figures you quote re-SF are very dated too but thats not the main issue .
No mention of milling costs at Osp .
Recovery ?
Net smelter royalty .
C'mon.....
I've done my own figures (which I admit ARE guesses) and I come up a payback period of 4.5 years over a mine life of 7 and a very low NPV and that just doesn't cut it for me .
