i doesn't get dug out of the ground in one go it's spread over 20-30 years even cascabel has so far taken 6 years to get to this point it is
as i've said before it takes 10 years to go from discovery to production with a porphyry system i'ld expect cascabel to be in-production for 6-7 before the new discovery comes on line
RIO's mine in Indonesia having all sorts of security problems at the moment as well as increasing demand new supply has plenty of upside that's not including the gold element in it all as well
