The $US182M of HGZ material (11.65% Cu) is contained in 210,000 tones of ore.
The total cost, (including grade control and moving the lower grade ore aside and do some blasting), to dig this out of the ground and sit it on a pad is only about $US2M at most and quite possibly a fair bit less.
And it could all be completed in less than 3-6 months
Staggering
