Copper is still very resilient at 3.00 even after all the negative talk about China and a slowdown. If all that is true how come copper hadn't crashed down to at least 1.50-2.00 range or lower and even at those horrible prices SC is still profitable. And your telling me Teck doesn't want that ?

I agree. SC copper cost includes the sustaining cost as well too. Using Calandria as an example, their $1.60ish cost doesn't include that.
