objective model to estimate qbl mc and sp

If resource is validated at 200 - 250 million tonnes of bauxite.

A simple model is:

Option 1: $1 bankable per tonne
Produces a MC of ~225 million or SP of ~28 times today's close or a SP of 78.4 cents.

Option 2: $5 bankable per tonne
Produces a MC of ~1125 million or SP of ~140 times today's close or a SP of $3.92.

It all comes down to how much resource is validated and how much bankable per tonne the big boys put on it at this stage.

Is this consistent with other peoples pricing models?

You can see why experts are touting this as the next FMG in their objective reports.
