Looking at the recent week where they poured 496oz.
3300t x grade x 90%/31.1035 = 496
i.e. grade = 5.19 g/t
The question is how profitable is the mine at that grade....
The increased throughput must have a lowering cost effect as will the efforts to crush or the like at the A1 site before hauling (less rock) back to the mill at Maldon....
Shame they don't include more numbers eg costs!
