The SAG mill design is based on Outotec's proprietary grinding mill technology, developed over decades for maximum reliability and performance. The mill will be operated as a single stage SAG mill (primary and secondary duty combined) with very high throughput made possible by the use of Outotec's patented Turbo Pulp Lifter (TPL(TM)) Technology.

Ore is crushed in-pit, in three semi-mobile gyratory crushers. Overland conveyors feed two secondary crushers, and two mill trains each consisting of a 40 foot diameter 28 megawatt SAG mill twinned with a 44 foot length 22 megawatt Ball mill. The grinding mills are amongst the largest of their type currently operating in the world.
