Hi Unicrumba. I do not believe those numbers and with the passage of time, I will be proved right. To do that, the mining rate would have to double. Do you agree? The mining contractor is battling to feed the current 150 ton per hour.
Secondly, the screening area for treatment of 0.5mm material needs to be 60 percent larger than for 1mm because of reduced screening efficiency. Next time you take a look at Bald Hills DMS you will notice those 4 screens. They represent more than a quarter of the cost of the entire plant and to enlarge them is impossible because the structures are custom built.
So don't expect 300 tph after a quick $15m spend! Happy to take a wager with anybody.
