COMPOSITING
Compositing of all the assay data was completed on 2.5 m downhole intervals
honouring the interpretation of the geological solids. A 2.5 m composite was
selected because it corresponds to approximately a third of the cell size to be used in
the modelling process.
The backstitching process was used in the compositing routine to ensure all captured
sample material was included. The backstitching routine adjusts the composite
lengths for each individual borehole in order to compensate for the last sample
interval. Composites were completed separately for the West Zone and East Zone.
Table 14.5 summarizes the statistics for the boreholes after capping and
compositing.
