RE:RE:RE:NCU's CHARTNCU was late, because unlike all of those other stocks you mention, it wasn't actually producing commercial quantities of copper.
Now it is, with a clear path to much more production.
Agreed, lots of upside left here. Lots and lots.
As for the other copper producers, do your DD on metrics. Earnings and cash flow matter, don't just look at share price.
NG lays out in his posts the cash flow NCU will be making underground, than how much more an open pit could bring, which is WHY NCU has its upside.
Do the same with all mining stocks. There is no such thing as an NPV bank account, you can only deposit cash.
