Fields and how they are used

You must enter a value in Field 1. This will be used for reporting tonnes for all fields. Cumulative grades for all fields written to the Output file are prefixed with the underscore character to differentiate them from non-cumulative grades.

If a block value does not meet any of the cutoff criteria, grades will not be calculated for other fields.

If a block has values for field 1 that are above one of the cutoffs, the volume of the block will be included in the total volume reported. If the same block does not have values for estimate fields 2 - 10 then the average grade for these fields will be reduced, as the missing grades will be regarded as being zero.
