I don't think I've ever heard that the mill is capable of more than 5,500 tons of raw ore per day. I think they would be pleased with an average of 3,500 tons.
It is my understanding that 3,500 tons per day of raw ore should produce about 100-150 tons of concentrate.
The company has said that with the SX/EW they will produce about 160,000 pounds of copper per day.
Full capacity for con is 100 tons per day. 5000 tons of ore per day and mag is 1000 tons per day is my understanding. And the mill is not at full production/capacity right now; probably 1/2 except for mag.
