iron ore margins

i carry several iron ore companies
juch thought i'd share my past experiences

fmg is a great buy at the moment considering the upside
ago is in the same boat but much cheaper
brm same boat
srk same boat just not as advertised much
irm a hidden secret at the moment


company = resource = total shares = price
fmg = 3.5bt = 1.5 b = $2
ago = 2bt = 220 m = $1.15
brm = 1bt = 120 m = $.90c
srk = 1-2bt = 100 m = $.30c
irm = 1-2bt = 70 m = $.06c

this is just a rough comparison i would like to see who is going to make the biggest marginal increase
i'm sure this will be contraversial enough for now
