On this site, the most critical was the semi-autogenous grinding (SAG) mill, which runs 24/7 with a full load. At the moment, because the life of the mine is limited, they are running at full production, occasionally overloading the mill. When the mill stops, the production cannot be recovered, and it is the only mill on the site.
