Here are the calculations for the 620Mt target


QUOTE
"Back in December 2006 the company outlined a target (key word target ) deposit that was 4,000m's long 300m's wide and should be 150m's thick/deep based on RIO's Adacent Brockman deposit,

Now IF (Key word IF ) the whole area is mineralised we get a target thats 4,000x 300x 150x 3.5 (sg) = 630Mt's@60% Fe (note grade based on rock chip samples and RIO's adjacent project)

So Max Target = 630Mt's@60%Fe



Like I was saying this is the target whether they reach the whole amount is debatable, but what we do know is that they have sampled significant grades within their tennements and also they are smack bang in the middle of several billion plus deposits owned by RIO and FMG.

The likelyhood of a significant deposit is extremely high due to location


And here is an extract of JMS announcement back in december 2006
