what si it worth?

I found the following on another forum (experts, what is your opinion about these figures? Do you agree?!):

"just a few facts here
ranger reserves
29m tonnes
resources
102m tonnes
Jabaluka
reserves
67m tonnes
ok
what is uranium price
$45
5m tonnes produced $50m last year (2010)
ie 1 tonne produced $10 profit
5m tonnes produced $276m in 2009
ie 1 tonne produced $50
29m tonnes
ranger's reserves are worth between $290m and $1,450m
the company has $412m on its current account
it has 102m tonnes as a resources
Jabaluka is worth zero for now
Market cap = $1.4 bn
What do you reckon ranger is worth?
we know there is zero debt
$412 on the current account
Ranger is probably worth about $800m (half the top price)
so that is $1,200m
only $200m to get to the market cap
the 102m tonnes of resource would cover that easily
what would that be worth?
at least $800 m
I reckon the stock is worth $2bn
ok $2bn / 190m shares = $10.53
hey this stock is worth at least $8.50!!!!
and what happens if it gets Jabaluka up and running
the mind boggles".
