Ann: West Kalkaroo Gold Drilling Results, page-9

"do you know if they've extensively tested the bedrock at west Kalkaroo? I understand that they would need a different drilling method to achieve this"

@Lotirish

Yes, the West Kalkaroo bedrock (which includes Partially oxidised, secondary sulphide ore zone - Chalcocite dominant with gold; and Primary sulphide ore zone - chalcopyrite dominant with gold and locally rich molybdenum) has been drilled via RC and DD drill holes. Some RC and DD drill holes at West Kalkaroo are shown in the photo below (from ASX Media Release dated 27 March 2017).





In addition, if you have time, Dr Giles explains all the drilling undertaken at West Kalkaroo in the following AIG video from calendar year 2013, at the 26 minute 18 second mark:
