Automating material tracking through the coarse ore stockpile.
The idea behind a coarse ore stockpile (COS) is to reduce material hardness and grade variations in the mill. There is enough material change to detect from the incoming and outgoing material given the relatively small size of most COSs. If we achieve a perfect, uniform blend, the problem would be solved.

Ore Stockpiling – Why are we doing this again?
1) Will the stockpile oxidize over time? If so how will this affect recovery? 2) What recovery factor should be used for fresh stockpile? Should it be the same as for run of mill ore? Most planners use the same number. 3) Is the stockpile grade tested or is is just a mathematical calculation at month end reconciliation?
