According to preliminary evaluations AS MOQC makes it possible to sort waste rock, which results in 2-3% losses decrease, 5-6% dilution reduction and therefore about 1-3% mined ore grade increase.
Since it is very difficult to mine ore according to surveying rods(especially in the night time),it results in unnecessary ore losses and its dilution by the waste rock.
ISR does not bring waste rock and ore to the surface, and create waste rock dumps and tailings dams, so there is no dust dispersion from mine waste facilities.
In addition to this being a low cost method of extraction,there is relatively little surface disturbance and no tailings or waste rock are generated.
