cdu's mined copper reserves, page-20

"Cudeco haven't technically proved any of the deposit is viable to extract but so far they have viably extracted 700 000 tonne and eventually 30 million tonne all without proving it is viable. They have just about built a plant without a BFS, are mining without reserves, consistently "

Well, actually they haven't shown that any of the mining they have done is viable as they haven't released any numbers nor have they sold anything.
