Ore Stockpiling – Why are we doing this again?

1. Campaigning: For metallurgical reasons if there are some ore types that can cause process difficulties if mixed with other ores. The problematic ore might be stockpiled until sufficient inventory allows one to process that ore (i.e. campaign) through the mill. Such stockpiles will only grow as large as the operator allows them to grow.
