20 years From production, guys.

Hence no income until 2014.

50MT = 100M per year. At least 1B for 20 years, it is also indexed to inflation, so not just $2 per tonne.

Under the terms of the new deal, Linc will be paid $500 million in cash by Adani Mining Pty Ltd, and $2 per tonne of royalty, indexed to inflation, for the first 20 years of production from the site.
Linc chief executive Peter Bond said it was expected Adani would begin producing thermal coal from the site from 2014
