Both the free milling and refractory ores will be processed through a standard crushing and milling circuit. From there, gold from the free milling ore will be recovered through the upgraded gravity CIL plant followed by production of gold doré bars. Refractory ore will be diverted after the milling process through the flotation circuit to

An additional secondary crushing circuit and two Verti mills were installed at the plant to further process the hard ore from Ridgeway Deeps. The secondary crushing circuit maintains high grades. The first Verti mill, which was installed in the ball mill circuit, has allowed for high throughput. The second mill is installed within the flotation circuit for regrinding works.

A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the disadvantage of not controlling the top size of feed to the ball-mill circuit. There have also been pioneer installations that have installed HPGRs as a second stage of pebble crushing.
