The third SAG mill fresh feed, referred as "Secondary Crushing", simulated the size distribution generated from a crushing circuit configured with primary and secondary stages. In all but one test, there were four open pebble ports, which consisted of relatively large apertures (76 mm × 76 mm) located around the mill grate.

Different combinations of SAG mill ball charge and grate open area were tested until 2006. A higher load level was achieved after several changes in the grate design that prevented both liner and grate breakage. Upon resolution of issues related to the mill grate design the project achieved the target throughput of 41 kt/d.

AG mills crush the ore without the need for iron or steel grinding media. They are used when the ore is hard enough for the tumbling ore to grind itself. In SAG milling, ∼ m 3 of 13 cm diameter iron or steel balls are added into the mill per m 3 of ore (, 15 vol.% "steel") to assist grinding. SAG mills are much more common.
