$20 a share in three years seems like one of the BEST possible outcomes IF everything goes their way (see my previous, much maligned but accurate, posts detailing this).
If I had to handicap the price 3 yrs from now it I'd say:
bankruptcy: 45% less than current trading price but not bankrupt: 15% 3.5-5 bucks p/s: 20% 5-20 bucks: 15% 20+: 5%
that said- I like those odds, especially in this market. but let's keep things reasonable. claiming RIO has any interest in a company with no income and no operating mines seems rather speculative to me, and that's the sort of thing that needs to be reflected in discussions and in share price. is there a potential upside here? of course, but consider the VERY high liklihood of a downside. best of luck to all.
