Ok so some quick back of envelope gross figures:
Plannned initial production of 5MT pa at 1.65% and a long term avg price of $1000 per tonne = $82.5 million dollars gross pa.
JORC resource of 400MT at 1.65% = $6.6 billion dollars gross
JORC proved and porbable reserve of 132MT = $2.178 billion extra in ground (potentially)

Huge numbers for a project whose resource should triple in size once further drilled and JORC'd down the track..
