Tracing Stocked Blocks
There are two common ways that mining software packages deal with stockpiles:
Reclaiming blocks according to an average grade for the entire stockpile.
Reclaiming blocks selectively in any required sequence such as FIFO, LIFO etc.
Both options are approximations and have their advantages and disadvantages.
How to trace blocks?
The user can analyze SimSched’s output in the files MinedBlocks or AllBlocks and report the periods in which a block has been mined and when it has been processed.
FIFO = First in, first out
LIFO = Last in, first out
