sfr v cdu, page-15

thanks hoots for the refresher course, funnily enough since august 18 i had put all things jorc out of my head..So while im on an education path, do we than at cdu need to upgrade from measured to probable? Is it really that important or are these catergories more related to finance? Will these reserve catergories effect the granting of lease? Sorry for my ignorance but im starting to wonder whether bulk sampling is more important to some than others. Can you begin mining say the measured areas and just upgrade as you go along or does asx require more?? Now i am confused did we even need all the worry about the jorc??
