For the first few years, the SAG mill charge was measured during scheduled downtime and the charging schedule updated accordingly. In late 2017, investigations of the comminution circuit concluded that the SAG mill was not consuming its maximum power draw capability when operating at a 14% to 16% ball charge and 68% to 74% critical speed.

Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
