The open-pit mining cycle includes drilling ore and waste rock, loading drill holes with explosives, blasting, ore loading and hauling to stockpiles for processing, waste rock loading and hauling to the waste rock storage pile. Occasionally, drilling and blasting ore is not required and can simply be removed by what is known as free digging.
