You can buy for negative value

@toteman here you go:

Amn at 6c is a market cap of $23Million

see below but in summary:
Amn has 40% of Niobium Holdings which was valued at $32Million
Amn will have 27% of Tali Resources IPO which I expect to double i.e. at 40c this is value of $12Million for AMN
Amn has cash of $3Million
AMN has the Mackay Potash project which is worth whatever you feel like
so add that all up and it's easily +$50Million
i.e. more than double current share price

remember tax loss selling finishes monday and i then expect to see a significant re-rate to fair value i.e. not negative value which is where it is currently
