worst case scenario...liquidation value

if Prom hill is worth about A$4 bn
Capital cost of the mine = $1.3bn
Profit = $3bn

why wouldn't someone pay $2bn for it?

OK take out the $1bn owed to banks

then you'd have $1bn for shareholders or about 30c

then you have got
martabe
golden grove
century
avebury
rosebery
sepon copper
sepon gold

all the other mines could probably be sold for $2bn (afterall $6bn has been invested in these for mining equipment etc)

all up shareholders could get about $1 share if the company were wound up, all debts paid and proceeds paid to shareholders.

lets take an even worse case scenario.

if say prom hill were sold for $1bn and the rest of the projects were sold for another $1bn, after banks were paid off then we (shareholders) could get 30c

so worse case scenario is 30c
