Due to additional ball mill capacity being available under low tonnage conditions (, M4A material), the option of increasing the trommel screen aperture and sending coarser material to the ball mills should be considered. Due to the fineness of the M1 (high tonnage) SAG mill feed, this should have little impact on the ball mill circuits.
