The crushed ore is moved to the grinding feed stockpile using a front-end loader ("FEL"). The grinding circuit comprises a single 5.8 MW autogenous grinding ("AG") mill at 8.53 m diameter and 3.96m effective grinding length. The AG mill operates in closed circuit with a pebble crushing circuit and primary hydrocyclones.

This type of mill is only suited for those kind of ores which are of a fairly coarse nature, but once they are broken, they readily disintegrate into smaller sizes. Typically, this type of mill can produce a product with a fineness of less than 0.1 mm. Testing of materials is needed beforehand for determining the suitability of the ore for processing in an autogenous mill.
