The data supplied by Shore for this Resource Estimate consisted of 285 surface diamond core drillholes, 213 underground diamond core drillholes and 103 LDD holes (Figure 16.1), of which 96 LDD holes reported diamond sampling data. Seven LDD holes did not sample kimberlite due to drilling difficulties (e.g. hole collapse or deviation). Data were provided electronically by Shore. The following information was supplied:
diamond sample data in Access and Excel format files;
bulk density data in Excel format;
diamond drilling logs as Access and Excel format files;
geological wireframes as Gemcom format BT2 files; and
diamond valuation data.

P&E imported all collar, geology and LDD sample data into an Access format Gemcom database. LDD batch sample intervals were then back-tagged against the geological wireframes supplied by Shore and compared to the Shore geology logs. A small number of discrepancies were noted by P&E. The database had a very low rate of error overall and those discrepancies noted by P&E were resolved by Shore.
