why cdu has to be a lt investment, page-19

Hi all,i must commend you b007 and fengshuey on pretty balanced appraisal of a share you dont own and have a few issues with. To you guys and Charlie etc i was just wondering if when they start pulling the stuff out of the ground, there is higher grades for whatever reasons, does the jorc get upgraded to reflect this or is it just a case of thats what the jorc said but this in what we have? Now i didnt explain that very well, but what i mean is if native is found and other grades higher at start do they extrapolate it out by way of jorc or do they say that it may well be there but not here in areas you havent dug up yet? Sorry for bad way of wording this question, but i hope one of you knows what im trying to say. Thanks
