too many 'if's'

then the new Komunist president will tell to Bailey -
"Ah, what a nice mine. Now is mine".
and we lose our money.

However, this can not happen in Mexico I believe. Mexico is too close to USA, also MX is a "good country" - whatever that may means, I liked Venezuela too ;)

There are different risk, I think. At the moment Oil in Mexico is subsided (similar to Saudi Arabia). Minefinders and others, currently paying cents for gasoline and diesel. And everything in mine industry is running on oil, even electricity is generated with gasoline generators.

So, once MX runs out of oil, the minning costs will raise a lot in just 1 day. And defenetly this will hurt the share price.
